I suggest you to start from an existing solution and customize it to fit your needs, that's better than starting from scratch!
I was looking for the same thing and I fall on this open source solution, I hope it will help.
Frankly, I can't find a single reason to use MySQL rather than MSSQL. The issue before used to be cost but SQL Server 2005 Express is free and there are lots of web hosting companies which offer full hosting with sql server for less than $5.00 a month.
MSSQL is easier to use and has many features which do not exist in MySQL.
Determine the Windows Installation Date with WMIC
wmic os get installdate
Generator expressions are also possible:
target_link_libraries(
target_name
PUBLIC
libA
$<$<PLATFORM_ID:Windows>:wsock32>
PRIVATE
$<$<PLATFORM_ID:Linux>:libB>
libC
)
This will link libA, wsock32 & libC on Windows and link libA, libB & libC on Linux
As MDN Window.history() describes :
For top-level pages you can see the list of pages in the session history, accessible via the History object, in the browser's dropdowns next to the back and forward buttons.
For security reasons the History object doesn't allow the non-privileged code to access the URLs of other pages in the session history, but it does allow it to navigate the session history.
There is no way to clear the session history or to disable the back/forward navigation from unprivileged code. The closest available solution is the location.replace() method, which replaces the current item of the session history with the provided URL.
So there is no Javascript method to clear the session history, instead, if you want to block navigating back to a certain page, you can use the location.replace() method, and pass the page link as parameter, which will not push the page to the browser's session history list. For example, there are three pages:
a.html:
<!doctype html>
<html>
<head>
<title>a.html page</title>
<meta charset="utf-8">
</head>
<body>
<p>This is <code style="color:red">a.html</code> page ! Go to <a href="b.html">b.html</a> page !</p>
</body>
</html>
b.html:
<!doctype html>
<html>
<head>
<title>b.html page</title>
<meta charset="utf-8">
</head>
<body>
<p>This is <code style="color:red">b.html</code> page ! Go to <a id="jumper" href="c.html">c.html</a> page !</p>
<script type="text/javascript">
var jumper = document.getElementById("jumper");
jumper.onclick = function(event) {
var e = event || window.event ;
if(e.preventDefault) {
e.preventDefault();
} else {
e.returnValue = true ;
}
location.replace(this.href);
jumper = null;
}
</script>
</body>
c.html:
<!doctype html>
<html>
<head>
<title>c.html page</title>
<meta charset="utf-8">
</head>
<body>
<p>This is <code style="color:red">c.html</code> page</p>
</body>
</html>
With href link, we can navigate from a.html to b.html to c.html. In b.html, we use the location.replace(c.html)
method to navigate from b.html to c.html. Finally, we go to c.html*, and if we click the back button in the browser, we will jump to **a.html.
So this is it! Hope it helps.
sudo apt-get install php7.0-mysql
for php7.0 works well for me
Volatile and Atomic are two different concepts. Volatile ensures, that a certain, expected (memory) state is true across different threads, while Atomics ensure that operation on variables are performed atomically.
Take the following example of two threads in Java:
Thread A:
value = 1;
done = true;
Thread B:
if (done)
System.out.println(value);
Starting with value = 0
and done = false
the rule of threading tells us, that it is undefined whether or not Thread B will print value. Furthermore value is undefined at that point as well! To explain this you need to know a bit about Java memory management (which can be complex), in short: Threads may create local copies of variables, and the JVM can reorder code to optimize it, therefore there is no guarantee that the above code is run in exactly that order. Setting done to true and then setting value to 1 could be a possible outcome of the JIT optimizations.
volatile
only ensures, that at the moment of access of such a variable, the new value will be immediately visible to all other threads and the order of execution ensures, that the code is at the state you would expect it to be. So in case of the code above, defining done
as volatile will ensure that whenever Thread B checks the variable, it is either false, or true, and if it is true, then value
has been set to 1 as well.
As a side-effect of volatile, the value of such a variable is set thread-wide atomically (at a very minor cost of execution speed). This is however only important on 32-bit systems that i.E. use long (64-bit) variables (or similar), in most other cases setting/reading a variable is atomic anyways. But there is an important difference between an atomic access and an atomic operation. Volatile only ensures that the access is atomically, while Atomics ensure that the operation is atomically.
Take the following example:
i = i + 1;
No matter how you define i, a different Thread reading the value just when the above line is executed might get i, or i + 1, because the operation is not atomically. If the other thread sets i to a different value, in worst case i could be set back to whatever it was before by thread A, because it was just in the middle of calculating i + 1 based on the old value, and then set i again to that old value + 1. Explanation:
Assume i = 0
Thread A reads i, calculates i+1, which is 1
Thread B sets i to 1000 and returns
Thread A now sets i to the result of the operation, which is i = 1
Atomics like AtomicInteger ensure, that such operations happen atomically. So the above issue cannot happen, i would either be 1000 or 1001 once both threads are finished.
To add to @BrianBeech's answer, this is even more trimmed down in java 8:
jdbcTemplate.query("select string1,string2 from table where x=1", (ResultSet rs) -> {
HashMap<String,String> results = new HashMap<>();
while (rs.next()) {
results.put(rs.getString("string1"), rs.getString("string2"));
}
return results;
});
There is also the rather spiffy FileStream
, introduced in SQL Server 2008.
The event must be cancelable
. Adding an if
statement solves this issue.
if (e.cancelable) {
e.preventDefault();
}
In your code you should put it here:
if (this.isSwipe(swipeThreshold) && e.cancelable) {
e.preventDefault();
e.stopPropagation();
swiping = true;
}
The logic is not flawed. The statement
if x is y then x==y is also True
should never be read to mean
if x==y then x is y
It is a logical error on the part of the reader to assume that the converse of a logic statement is true. See http://en.wikipedia.org/wiki/Converse_(logic)
With the GnuWin32 tools I found the openssl.cnf under C:\gnuwin32\share
set OPENSSL_CONF=C:\gnuwin32\share\openssl.cnf
Simply \newpage
or \pagebreak
will work, e.g.
hello world
\newpage
```{r, echo=FALSE}
1+1
```
\pagebreak
```{r, echo=FALSE}
plot(1:10)
```
This solution assumes you are knitting PDF. For HTML, you can achieve a similar effect by adding a tag <P style="page-break-before: always">
. Note that you likely won't see a page break in your browser (HTMLs don't have pages per se), but the printing layout will have it.
Move doSomething
definition outside of its class declaration and after B
and also make add
accessible to A
by public
-ing it or friend
-ing it.
class B;
class A
{
void doSomething(B * b);
};
class B
{
public:
void add() {}
};
void A::doSomething(B * b)
{
b->add();
}
A faster way to
would be
:x
If you have opened multiple files you may need to do a
:xa
Use std::string
instead of char-arrays
std::string k ="abcde";
std::vector<std::string> v;
v.push_back(k);
Here's another way to do it. Some people will prefer this as the code is a bit cleaner. There are no %s
and a RESET
color to end the coloration.
#include <stdio.h>
#define RED "\x1B[31m"
#define GRN "\x1B[32m"
#define YEL "\x1B[33m"
#define BLU "\x1B[34m"
#define MAG "\x1B[35m"
#define CYN "\x1B[36m"
#define WHT "\x1B[37m"
#define RESET "\x1B[0m"
int main() {
printf(RED "red\n" RESET);
printf(GRN "green\n" RESET);
printf(YEL "yellow\n" RESET);
printf(BLU "blue\n" RESET);
printf(MAG "magenta\n" RESET);
printf(CYN "cyan\n" RESET);
printf(WHT "white\n" RESET);
return 0;
}
This program gives the following output:
This way, it's easy to do something like:
printf("This is " RED "red" RESET " and this is " BLU "blue" RESET "\n");
This line produces the following output:
According to High-performance Mysql book:
The only difference between the BLOB and TEXT families is that BLOB types store binary data with no collation or character set, but TEXT types have a character set and collation.
It's a new era and with Python 3.6.1 dictionaries now retain their order. These semantics aren't explicit because that would require BDFL approval. But Raymond Hettinger is the next best thing (and funnier) and he makes a pretty strong case that dictionaries will be ordered for a very long time.
So now it's easy to create slices of a dictionary:
test_dict = {
'first': 1,
'second': 2,
'third': 3,
'fourth': 4
}
list(test_dict.items())[:2]
Note: Dictonary insertion-order preservation is now official in Python 3.7.
import re
result=[x for x in re.split(',| ',your_string) if x!='']
this works fine for me.
If you can catch this in time and you don't have the ability to ROLLBACK
or use the transaction log, you can take a backup immediately and use a tool like Redgate's SQL Data Compare to generate a script to "restore" the affected data. This worked like a charm for me. :)
What exactly are you looking for when you mean multiline strings.
Are you looking for something like:
var str = "Some \
String \
Here";
Which would print as "Some String Here"?
If so, keep in mind that the above is valid Javascript, but this isn't:
var str = "Some \
String \
Here";
What's the difference? A space after the \
. Have fun debugging that.
PROTIP:
The RMI port are opened at arbitrary portnr's. If you have a firewall and don't want to open ports 1024-65535 (or use vpn) then you need to do the following.
You need to fix (as in having a known number) the RMI Registry and JMX/RMI Server ports. You do this by putting a jar-file (catalina-jmx-remote.jar it's in the extra's) in the lib-dir and configuring a special listener under server:
<Listener className="org.apache.catalina.mbeans.JmxRemoteLifecycleListener"
rmiRegistryPortPlatform="10001" rmiServerPortPlatform="10002" />
(And ofcourse the usual flags for activating JMX
-Dcom.sun.management.jmxremote \
-Dcom.sun.management.jmxremote.ssl=false \
-Dcom.sun.management.jmxremote.authenticate=false \
-Djava.rmi.server.hostname=<HOSTNAME> \
See: JMX Remote Lifecycle Listener at http://tomcat.apache.org/tomcat-6.0-doc/config/listeners.html
Then you can connect using this horrific URL:
service:jmx:rmi://<hostname>:10002/jndi/rmi://<hostname>:10001/jmxrmi
To avoid including a large framework, I think a simple homemade class can do the trick.
Example of class to handle named parameters:
public class NamedParamStatement {
public NamedParamStatement(Connection conn, String sql) throws SQLException {
int pos;
while((pos = sql.indexOf(":")) != -1) {
int end = sql.substring(pos).indexOf(" ");
if (end == -1)
end = sql.length();
else
end += pos;
fields.add(sql.substring(pos+1,end));
sql = sql.substring(0, pos) + "?" + sql.substring(end);
}
prepStmt = conn.prepareStatement(sql);
}
public PreparedStatement getPreparedStatement() {
return prepStmt;
}
public ResultSet executeQuery() throws SQLException {
return prepStmt.executeQuery();
}
public void close() throws SQLException {
prepStmt.close();
}
public void setInt(String name, int value) throws SQLException {
prepStmt.setInt(getIndex(name), value);
}
private int getIndex(String name) {
return fields.indexOf(name)+1;
}
private PreparedStatement prepStmt;
private List<String> fields = new ArrayList<String>();
}
Example of calling the class:
String sql;
sql = "SELECT id, Name, Age, TS FROM TestTable WHERE Age < :age OR id = :id";
NamedParamStatement stmt = new NamedParamStatement(conn, sql);
stmt.setInt("age", 35);
stmt.setInt("id", 2);
ResultSet rs = stmt.executeQuery();
Please note that the above simple example does not handle using named parameter twice. Nor does it handle using the : sign inside quotes.
You could create a List<Object>
, but you really don't want to do this. Mixed lists that abstract to Object are not very useful and are a potential source of bugs. In fact the fact that your code requires such a construct gives your code a bad code smell and suggests that its design may be off. Consider redesigning your program so you aren't forced to collect oranges with orangutans.
Instead -- do what G V recommends and I was about to recommend, create a custom class that holds both int and String and create an ArrayList of it. 1+ to his answer!
Simply put inside your script :
source FILE
Or
. FILE # POSIX compliant
$ LANG=C help source
source: source filename [arguments]
Execute commands from a file in the current shell.
Read and execute commands from FILENAME in the current shell. The
entries in $PATH are used to find the directory containing FILENAME.
If any ARGUMENTS are supplied, they become the positional parameters
when FILENAME is executed.
Exit Status:
Returns the status of the last command executed in FILENAME; fails if
FILENAME cannot be read.
grep '^[0-9]\{1,16\}' | wc -l
Gives the counts with exact match count with limit
This should do it:
for (var i = 0; i < bank_holidays.length; i++) {
if (bank_holidays[i] === '06/04/2012') {
alert('LOL');
}
}
You install as assemblies by using:
gacutil.exe
tool with the -i
option from the command line.%windir%\Assembly
(only up to .NET 3.5, CLR 2.0)You view the content of the GAC using:
gacutil.exe
tool with the -l
option.%windir%\assembly
using the Windows Explorer.Note that the (physical) GAC location has changed for .NET 4.0. It is no longer in %windir%\Assembly
, but now in %windir%\Microsoft.NET\assembly
. However, you should never write any code that depends on the physical location anyway, because given the tools available that is hardly necessary (some "cool" homegrown system diagnostics tools aside).
on duplicate key update, or insert ignore can be viable solutions with MySQL.
Example of on duplicate key update update based on mysql.com
INSERT INTO table (a,b,c) VALUES (1,2,3)
ON DUPLICATE KEY UPDATE c=c+1;
UPDATE table SET c=c+1 WHERE a=1;
Example of insert ignore based on mysql.com
INSERT [LOW_PRIORITY | DELAYED | HIGH_PRIORITY] [IGNORE]
[INTO] tbl_name [(col_name,...)]
{VALUES | VALUE} ({expr | DEFAULT},...),(...),...
[ ON DUPLICATE KEY UPDATE
col_name=expr
[, col_name=expr] ... ]
Or:
INSERT [LOW_PRIORITY | DELAYED | HIGH_PRIORITY] [IGNORE]
[INTO] tbl_name
SET col_name={expr | DEFAULT}, ...
[ ON DUPLICATE KEY UPDATE
col_name=expr
[, col_name=expr] ... ]
Or:
INSERT [LOW_PRIORITY | HIGH_PRIORITY] [IGNORE]
[INTO] tbl_name [(col_name,...)]
SELECT ...
[ ON DUPLICATE KEY UPDATE
col_name=expr
[, col_name=expr] ... ]
Here you get all available services and their status in your local machine.
ServiceController[] services = ServiceController.GetServices();
foreach(ServiceController service in services)
{
Console.WriteLine(service.ServiceName+"=="+ service.Status);
}
You can Compare your service with service.name property inside loop and you get status of your service. For details go with the http://msdn.microsoft.com/en-us/library/system.serviceprocess.servicecontroller.aspx also http://msdn.microsoft.com/en-us/library/microsoft.windows.design.servicemanager(v=vs.90).aspx
If you wrap your form elements in a form tag with a name attribute you can easily get the value using document.formName.radioGroupName.value.
<form name="myForm">
<input type="radio" id="genderm" name="gender" value="male" />
<label for="genderm">Male</label>
<input type="radio" id="genderf" name="gender" value="female" />
<label for="genderf">Female</label>
</form>
<script>
var selected = document.forms.myForm.gender.value;
</script>
As a one-liner into vim:
:set tabstop=4 shiftwidth=4
For permanent setup, add these lines to ~/.vimrc:
set tabstop=4
set shiftwidth=4
NOTE: Add set expandtab
if you prefer 4-spaces indentation, instead of a tab indentation.
Edit: Now compatible with MSVC, C++ and non-GNU compilers (see end).
The question was "most efficient way." The OP doesn't specify platform, he could be compiling for a RISC based ATMEL chip with 256 bytes of flash storage for his code.
For the record, and for those (like me), who appreciate the difference between "the easiest way" and the "most efficient way", and who enjoy learning...
static const long hextable[] = {

It requires no external libraries, and it should be blindingly fast. It handles uppercase, lowercase, invalid characters, odd-sized hex input (eg: 0xfff), and the maximum size is limited only by the compiler.
For non-GCC or C++ compilers or compilers that will not accept the fancy hextable declaration.
Replace the first statement with this (longer, but more conforming) version:
static const long hextable[] = {
-1,-1,-1,-1,-1,-1,-1,-1,-1,-1,-1,-1,-1,-1,-1,-1,-1,-1,-1,-1,-1,-1,-1,

For Swift 2, you should change it to the following:
func locationManager(manager: CLLocationManager, didUpdateLocations locations: [CLLocation]) {
let location = locations.last
let center = CLLocationCoordinate2D(latitude: location!.coordinate.latitude, longitude: location!.coordinate.longitude)
let region = MKCoordinateRegion(center: center, span: MKCoordinateSpan(latitudeDelta: 0.01, longitudeDelta: 0.01))
self.map.setRegion(region, animated: true)
}
For the timer part of your script i highly reccomend using:
echo.
echo Waiting For One Hour...
TIMEOUT /T 3600 /NOBREAK
echo.
echo (Put some Other Processes Here)
echo.
pause >nul
This script waits for 1 hour (3600 seconds) and then continues on with the script and the user cannot press any buttons to bypass the timer (besides CTRL+C).
You can use
Timeout /t 3600 /nobreak >nul
If you don't want to see a countdown on the screen.
Bash does not supports multidimensional array, but we can implement using Associate array. Here the indexes are the key to retrieve the value. Associate array is available in bash

You can handle loading the excel file content by writing Java code using Apache POI library (https://poi.apache.org/). The library is developed for working with MS office application data including Excel.
I have recently created the application based on the technology that will help you to load Excel files to the Postgres database. The application is available under http://www.abespalov.com/. The application is tested only for Windows, but should work for Linux as well.
The application automatically creates necessary tables with the same columns as in the Excel files and populate the tables with content. You can export several files in parallel. You can skip the step to convert the files into the CSV format. The application handles the xls and xlsx formats.
Overall application stages are :
{
fileExtension = FilenameUtils.getExtension(inputSheetFile.getName());
if (fileExtension.equalsIgnoreCase("xlsx")) {
workbook = createWorkbook(openOPCPackage(inputSheetFile));
} else {
workbook =
createWorkbook(openNPOIFSFileSystemPackage(inputSheetFile));
}
sheet = workbook.getSheetAt(0);
}
{
Iterator<Row> rowIterator = InitInputFilesImpl.sheet.rowIterator();
//skip a header
if (rowIterator.hasNext()) {
rowIterator.next();
}
while (rowIterator.hasNext()) {
Row row = (Row) rowIterator.next();
// inserting rows
}
}
Here you can find all Java code for the application created for exporting excel to Postgres (https://github.com/palych-piter/Excel2DB).
To access a single value you can use the method iat
that is much faster than iloc
:
df['Btime'].iat[0]
Output:

WORKAROUND:
The possible workaround is modify your project's platform from 'Any CPU' to 'X86' (in Project's Properties, Build/Platform's Target)
ROOTCAUSE
The VSS Interop is a managed assembly using 32-bit Framework and the dll contains a 32-bit COM object. If you run this COM dll in 64 bit environment, you will get the error message.
You can use the below code on your string and you will get the complete string without html part.
string title = "<b> Hulk Hogan's Celebrity Championship Wrestling <font color=\"#228b22\">[Proj # 206010]</font></b> (Reality Series, )".Replace(" ",string.Empty);
string s = Regex.Replace(title, "<.*?>", String.Empty);
An easy way which allows you to omit any parameters in any position, is taking advantage of nullable types as follows:
public void PrintValues(int? a = null, int? b = null, float? c = null, string s = "")
{
if(a.HasValue)
Console.Write(a);
else
Console.Write("-");
if(b.HasValue)
Console.Write(b);
else
Console.Write("-");
if(c.HasValue)
Console.Write(c);
else
Console.Write("-");
if(string.IsNullOrEmpty(s)) // Different check for strings
Console.Write(s);
else
Console.Write("-");
}
Strings are already nullable types so they don't need the ?.
Once you have this method, the following calls are all valid:
PrintValues (1, 2, 2.2f);
PrintValues (1, c: 1.2f);
PrintValues(b:100);
PrintValues (c: 1.2f, s: "hello");
PrintValues();
When you define a method that way you have the freedom to set just the parameters you want by naming them. See the following link for more information on named and optional parameters:
Highlight the cells, format cells, select Custom then select zero.
You need to start by understanding that the target of a symlink is a pathname. And it can be absolute or relative to the directory which contains the symlink
Assuming you have foo.conf in sites-available
Try
cd sites-enabled
sudo ln -s ../sites-available/foo.conf .
ls -l
Now you will have a symlink in sites-enabled called foo.conf which has a target ../sites-available/foo.conf
Just to be clear, the normal configuration for Apache is that the config files for potential sites live in sites-available and the symlinks for the enabled sites live in sites-enabled, pointing at targets in sites-available. That doesn't quite seem to be the case the way you describe your setup, but that is not your primary problem.
If you want a symlink to ALWAYS point at the same file, regardless of the where the symlink is located, then the target should be the full path.
ln -s /etc/apache2/sites-available/foo.conf mysimlink-whatever.conf
Here is (line 1 of) the output of my ls -l /etc/apache2/sites-enabled:
lrwxrwxrwx 1 root root 26 Jun 24 21:06 000-default -> ../sites-available/default
See how the target of the symlink is relative to the directory that contains the symlink (it starts with ".." meaning go up one directory).
Hardlinks are totally different because the target of a hardlink is not a directory entry but a filing system Inode.
You can also use numpy loadtxt like
from numpy import loadtxt
lines = loadtxt("filename.dat", comments="#", delimiter=",", unpack=False)
Also make sure that you don't declare it an array and then try to assign something else to the array like a string, float, integer. I had that problem. If you do some echos of output I was seeing what I wanted the first time, but not after another pass of the same code.

If you can live with 01 for January instead of 1, then try...
d = datetime.datetime.strptime("2013-1-25", '%Y-%m-%d')
print datetime.date.strftime(d, "%m/%d/%y")

In case you are using node.js (with express)
If you want to serve static files in node.js, you need to use a function. Add the following code to your js file:
app.use(express.static("public"));
Where app is:
const express = require("express");
const app = express();
Then create a folder called public in you project folder. (You could call it something else, this is just good practice but remember to change it from the function as well.)
Then in this file create another folder named css (and/or images file under css if you want to serve static images as well.) then add your css files to this folder.
After you add them change the stylesheet accordingly. For example if it was:
href="cssFileName.css"
and
src="imgName.png"
Make them:
href="css/cssFileName.css"
src="css/images/imgName.png"
That should work
use window.localStorage... like this
var refresh = $window.localStorage.getItem('refresh');
console.log(refresh);
if (refresh===null){
window.location.reload();
$window.localStorage.setItem('refresh', "1");
}
It's work for me

Thanks for help. This is the solution: I created the subview and i add a gesture to remove it
@IBAction func infoView(sender: UIButton) {
var testView: UIView = UIView(frame: CGRectMake(0, 0, 320, 568))
testView.backgroundColor = UIColor.blueColor()
testView.alpha = 0.5
testView.tag = 100
testView.userInteractionEnabled = true
self.view.addSubview(testView)
let aSelector : Selector = "removeSubview"
let tapGesture = UITapGestureRecognizer(target:self, action: aSelector)
testView.addGestureRecognizer(tapGesture)
}
func removeSubview(){
println("Start remove sibview")
if let viewWithTag = self.view.viewWithTag(100) {
viewWithTag.removeFromSuperview()
}else{
println("No!")
}
}
Update:
Swift 3+
@IBAction func infoView(sender: UIButton) {
let testView: UIView = UIView(frame: CGRect(x: 0, y: 0, width: 320, height: 568))
testView.backgroundColor = .blue
testView.alpha = 0.5
testView.tag = 100
testView.isUserInteractionEnabled = true
self.view.addSubview(testView)
let aSelector : Selector = #selector(GasMapViewController.removeSubview)
let tapGesture = UITapGestureRecognizer(target:self, action: aSelector)
testView.addGestureRecognizer(tapGesture)
}
func removeSubview(){
print("Start remove sibview")
if let viewWithTag = self.view.viewWithTag(100) {
viewWithTag.removeFromSuperview()
}else{
print("No!")
}
}
I had a similar problem. I wanted to know whether the server is connected to client or the client is connected to server. In such circumstances the return value of the recv function can come in handy. If the socket is not connected it will return 0 bytes. Thus using this I broke the loop and did not have to use any extra threads of functions. You might also use this same if experts feel this is the correct method.
In general the best way is to Change the table collation. However I have an old application and are not really able to estimate the outcome whether this has side effects. Therefore I tried somehow to convert the string into some other format that solved the collation problem.
What I found working is to do the string compare by converting the strings into a hexadecimal representation of it's characters. On the database this is done with HEX(column).
For PHP you may use this function:
public static function strToHex($string)
{
$hex = '';
for ($i=0; $i<strlen($string); $i++){
$ord = ord($string[$i]);
$hexCode = dechex($ord);
$hex .= substr('0'.$hexCode, -2);
}
return strToUpper($hex);
}
When doing the database query, your original UTF8 string must be converted first into an iso string (e.g. using utf8_decode()
in PHP) before using it in the DB. Because of the collation type the database cannot have UTF8 characters inside so the comparism should work event though this changes the original string (converting UTF8 characters that are not existend in the ISO charset result in a ? or these are removed entirely). Just make sure that when you write data into the database, that you use the same UTF8 to ISO conversion.
Use the spec parameter.
Instructions below.
Create a new javascript file in the same directory as index.html (/dist/)
Then insert spec
variable declaration:
var spec =
Then paste in the swagger.json file contents after. It does not have to be on the same line as the =
sign.
Example:
var spec =
{
"swagger": "2.0",
"info": {
"title": "I love Tex-Mex API",
"description": "You can barbecue it, boil it, broil it, bake it, sauté it. Dey's uh, Tex-Mex-kabobs, Tex-Mex creole, Tex-Mex gumbo. Pan fried, deep fried, stir-fried. There's pineapple Tex-Mex, lemon Tex-Mex, coconut Tex-Mex, pepper Tex-Mex, Tex-Mex soup, Tex-Mex stew, Tex-Mex salad, Tex-Mex and potatoes, Tex-Mex burger, Tex-Mex sandwich..",
"version": "1.0.0"
},
...
}
}
This is a two-step like Ciara.
Modify the /dist/index.html file to include the external spec.js
file.
<script src='spec.js' type="text/javascript"></script>
Example:
<!-- Some basic translations -->
<!-- <script src='lang/translator.js' type='text/javascript'></script> -->
<!-- <script src='lang/ru.js' type='text/javascript'></script> -->
<!-- <script src='lang/en.js' type='text/javascript'></script> -->
<!-- Original file pauses -->
<!-- Insert external modified swagger.json -->
<script src='spec.js' type="text/javascript"></script>
<!-- Original file resumes -->
<script type="text/javascript">
$(function () {
var url = window.location.search.match(/url=([^&]+)/);
if (url && url.length > 1) {
url = decodeURIComponent(url[1]);
} else {
url = "http://petstore.swagger.io/v2/swagger.json";
}
Modify the SwaggerUi instance to include the spec
parameter:
window.swaggerUi = new SwaggerUi({
url: url,
spec: spec,
dom_id: "swagger-ui-container",
You could do:
class myClass : ICloneable
{
public String test;
public object Clone()
{
return this.MemberwiseClone();
}
}
then you can do
myClass a = new myClass();
myClass b = (myClass)a.Clone();
N.B. MemberwiseClone()
Creates a shallow copy of the current System.Object.
I don't know why those commands are not working for you, but you can also try timeout
timeout <delay in seconds>
Look at java.lang.BigDecimal, may solve your problem.
http://docs.oracle.com/javase/7/docs/api/java/math/BigDecimal.html
What missing for me was I was using
import { Router, Route, browserHistory, IndexRoute } from 'react-router';
instead or correct answer should be :
import { BrowserRouter as Router, Route } from 'react-router-dom';
Ofcourse you need to add npm package react-router-dom:
npm install react-router-dom@next --save
System.IO.Path.GetTempPath()
is just a wrapper for a native call to GetTempPath(..)
in Kernel32.
Have a look at http://msdn.microsoft.com/en-us/library/aa364992(VS.85).aspx
Copied from that page:
The GetTempPath function checks for the existence of environment variables in the following order and uses the first path found:
- The path specified by the TMP environment variable.
- The path specified by the TEMP environment variable.
- The path specified by the USERPROFILE environment variable.
- The Windows directory.
It's not entirely clear to me whether "The Windows directory" means the temp directory under windows or the windows directory itself. Dumping temp files in the windows directory itself sounds like an undesirable case, but who knows.
So combining that page with your post I would guess that either one of the TMP, TEMP or USERPROFILE variables for your Administrator user points to the windows path, or else they're not set and it's taking a fallback to the windows temp path.
you should use go modules now, if you are not following How to write go code
With go module you don't have to put the code in the $GOPATH/src. it can live in any other location as well.
You can move the code to different directory like /employee, To make it work Just under employee directory initialise the go module
go mod init example.com/employee
$('#google').attr('onclick') + ""
However, Firebug shows that this returns a function 'onclick'. You can call the function later on using the following approach:
(new Function ($('#google').attr('onclick') + ';onclick();'))()
... or use a RegEx to strip the function
and get only the statements within it.
jQuery Ajax loader is not working well when you call two APIs simultaneously. To resolve this problem you have to call the APIs one by one using the isAsync
property in Ajax setting. You also need to make sure that there should not be any error in the setting. Otherwise, the loader will not work. E.g undefined content-type, data-type for POST/PUT/DELETE/GET call.
Use git clone
with the --depth
option set to 1
to create a shallow clone with a history truncated to the latest commit.
For example:
git clone --depth 1 https://github.com/user/repo.git
To also initialize and update any nested submodules, also pass --recurse-submodules
and to clone them shallowly, also pass --shallow-submodules
.
For example:
git clone --depth 1 --recurse-submodules --shallow-submodules https://github.com/user/repo.git
Use different format or pattern to get the information from the date
var myDate = new Date("2015-06-17 14:24:36");_x000D_
console.log(moment(myDate).format("YYYY-MM-DD HH:mm:ss"));_x000D_
console.log("Date: "+moment(myDate).format("YYYY-MM-DD"));_x000D_
console.log("Year: "+moment(myDate).format("YYYY"));_x000D_
console.log("Month: "+moment(myDate).format("MM"));_x000D_
console.log("Month: "+moment(myDate).format("MMMM"));_x000D_
console.log("Day: "+moment(myDate).format("DD"));_x000D_
console.log("Day: "+moment(myDate).format("dddd"));_x000D_

The actual problem of this error has nothing to do with file_get_content, the problem is the requested url if the url is not throwing content of the page and redirecting the request to some where else file_get_content says "Failed to open stream", just before file_get_contents check whether the url is working and not redirecting, here is the code:
function checkRedirect404($url) {
$ch = curl_init();
curl_setopt($ch, CURLOPT_HEADER, true);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_URL, $url);
$out = curl_exec($ch);
// line endings is the wonkiest piece of this whole thing
$out = str_replace("\r", "", $out);
// only look at the headers
$headers_end = strpos($out, "\n\n");
if( $headers_end !== false ) {
$out = substr($out, 0, $headers_end);
}
$headers = explode("\n", $out);
foreach($headers as $header) {
if( substr($header, 0, 10) == "Location: " ) {
$target = substr($header, 10);
//echo "Redirects: $target<br>";
return true;
}
}
return false;
}
you need just in scss varible
$input-btn-focus-width: .05rem !default;
This script below should put you on the right track perhaps?
You can keep this html the same (though I changed the method to POST):
<form method="POST" id="subscribeForm">
<fieldset id="cbgroup">
<div><input name="list" id="list0" type="checkbox" value="newsletter0" >zero</div>
<div><input name="list" id="list1" type="checkbox" value="newsletter1" >one</div>
<div><input name="list" id="list2" type="checkbox" value="newsletter2" >two</div>
</fieldset>
<input name="submit" type="submit" value="submit">
</form>
and this javascript validates
function onSubmit()
{
var fields = $("input[name='list']").serializeArray();
if (fields.length === 0)
{
alert('nothing selected');
// cancel submit
return false;
}
else
{
alert(fields.length + " items selected");
}
}
// register event on form, not submit button
$('#subscribeForm').submit(onSubmit)
and you can find a working example of it here
UPDATE (Oct 2012)
Additionally it should be noted that the checkboxes must have a "name" property, or else they will not be added to the array. Only having "id" will not work.
UPDATE (May 2013)
Moved the submit registration to javascript and registered the submit onto the form (as it should have been originally)
UPDATE (June 2016)
Changes == to ===
You should use getFullYear()
instead of getYear()
. getYear()
returns the actual year minus 1900 (and so is fairly useless).
Thus a date marking exactly one year from the present moment would be:
var oneYearFromNow = new Date();
oneYearFromNow.setFullYear(oneYearFromNow.getFullYear() + 1);
Note that the date will be adjusted if you do that on February 29.
Similarly, you can get a date that's a month from now via getMonth()
and setMonth()
. You don't have to worry about "rolling over" from the current year into the next year if you do it in December; the date will be adjusted automatically. Same goes for day-of-month via getDate()
and setDate()
.
I had the same problem that is really easy to make, but took me a while to see through.
I had copied the declaration to where I was using it and had left the 'self' argument there, but it took me ages to realise that.
I had
self.myFunction(self, a, b, c='123')
but it should have been
self.myFunction(a, b, c='123')
Crockford has done a lot to popularize good JavaScript techniques. His opinionated stance on key elements of the language have sparked many useful discussions. That said, there are far too many people that take each proclamation of "bad" or "harmful" as gospel, refusing to look beyond one man's opinion. It can be a bit frustrating at times.
Use of the functionality provided by the new
keyword has several advantages over building each object from scratch:
prototype
and use new
to stamp out new objects. Not only is this faster (no code needed for each and every method on the prototype), it avoids ballooning each object with separate properties for each method. On slower machines (or especially, slower JS interpreters) when many objects are being created this can mean a significant savings in time and memory.And yes, new
has one crucial disadvantage, ably described by other answers: if you forget to use it, your code will break without warning. Fortunately, that disadvantage is easily mitigated - simply add a bit of code to the function itself:
function foo()
{
// if user accidentally omits the new keyword, this will
// silently correct the problem...
if ( !(this instanceof foo) )
return new foo();
// constructor logic follows...
}
Now you can have the advantages of new
without having to worry about problems caused by accidentally misuse. You could even add an assertion to the check if the thought of broken code silently working bothers you. Or, as some commented, use the check to introduce a runtime exception:
if ( !(this instanceof arguments.callee) )
throw new Error("Constructor called as a function");
(Note that this snippet is able to avoid hard-coding the constructor function name, as unlike the previous example it has no need to actually instantiate the object - therefore, it can be copied into each target function without modification.)
John Resig goes into detail on this technique in his Simple "Class" Instantiation post, as well as including a means of building this behavior into your "classes" by default. Definitely worth a read... as is his upcoming book, Secrets of the JavaScript Ninja, which finds hidden gold in this and many other "harmful" features of the JavaScript language (the chapter on with
is especially enlightening for those of us who initially dismissed this much-maligned feature as a gimmick).
based on @mister_lucky answer use with jquery:
$('#unobtrusive').on('click',function (e) {
e.preventDefault(); //optional
//some code
});
Html Code:
<a id="unobtrusive" href="http://jquery.com">jquery</a>
Could you give some indication of what platforms you are writing for? This should weigh heavily on what is 'best'. You might find a super 'xml-foo' library that does not ship commonly on most systems by default .. while its great, the lack of the library might prevent (or at least) annoy users.
Mostly, I use libxml2 .. because its standard or easy to install on the platforms that I target.
As you see, 'best' is also determined by the library being available on your target platforms.
Import the Support Libraries, In your project's build.gradle file, add the following lines in the project's dependencies:
dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
compile 'com.android.support:design:22.2.0'
compile 'com.android.support:appcompat-v7:22.2.0'
}
Use following TextInputLayout in your UI Layout:
<android.support.design.widget.TextInputLayout
android:id="@+id/usernameWrapper"
android:layout_width="match_parent"
android:layout_height="wrap_content">
<EditText
android:id="@+id/username"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:inputType="textEmailAddress"
android:hint="Username"/>
</android.support.design.widget.TextInputLayout>
Than, call setHint on TextInputLayout just after setContentView call because, to animate the floating label, you just need to set a hint, using the setHint method.
final TextInputLayout usernameWrapper = (TextInputLayout) findViewById(R.id.usernameWrapper);
usernameWrapper.setHint("Username");
You can connect your XML schema to Microsoft Visual Studio's Intellisense. This option gives you both real-time validation AND autocomplete, which is just awesome.
I have this exact scenario running on my free copy of Microsoft Visual C++ 2010 Express.
If you want the file to be opened with the default application, I mean without specifying Acrobat or Reader, you can't open the file in the specified page.
On the other hand, if you are Ok with specifying Acrobat or Reader, keep reading:
You can do it without telling the full Acrobat path, like this:
Process myProcess = new Process();
myProcess.StartInfo.FileName = "acroRd32.exe"; //not the full application path
myProcess.StartInfo.Arguments = "/A \"page=2=OpenActions\" C:\\example.pdf";
myProcess.Start();
If you don't want the pdf to open with Reader but with Acrobat, chage the second line like this:
myProcess.StartInfo.FileName = "Acrobat.exe";
You can query the registry to identify the default application to open pdf files and then define FileName on your process's StartInfo accordingly.
Follow this question for details on doing that: Finding the default application for opening a particular file type on Windows
Try this sqlite table schema parser, I implemented the sqlite table parser for parsing the table definitions in PHP.
It returns the full definitions (unique, primary key, type, precision, not null, references, table constraints... etc)
Try imaskjs. It has Number, RegExp and other masks. Very simple to extend.
The subversion client itself is available on Windows. See here for certified binaries from CollabNet.
CollabNet Subversion Command-Line Client v1.6.9 (for Windows)
This installer only includes the command-line client and an auto-update component.
Even though I can't understand it's possible not to love Tortoise! :)
Note:
The above link is for newer products - you can find version 1.11.1 through 1.7.19 at Older Subversion Releases
Nick has the right answer, but I wanted to add you could also get the cell data without needing the class name
var Something = $(this).closest('tr').find('td:eq(1)').text();
:eq(#)
has a zero based index (link).
this is the easiest way that you could print the String by using array!!!
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
namespace arraypracticeforstring
{
class Program
{
static void Main(string[] args)
{
string[] arr = new string[3] { "Snehal", "Janki", "Thakkar" };
foreach (string item in arr)
{
Console.WriteLine(item.ToString());
}
Console.ReadLine();
}
}
}
Note: Don’t confuse RUN with CMD. RUN actually runs a command and commits the result; CMD does not execute anything at build time, but specifies the intended command for the image.

Many people will feel surprised maybe, but this question is incorrect. If you hear this question during an interview, you need to help the interviewer understand where the confusion is.
Let's start from the fact that there is no concrete pattern that is called just "Factory". There is pattern that is called "Abstract Factory", and there is pattern that is called "Factory Method".
So, what does "Factory" mean then? one of the following (all can be considered correct, depending on the scope of the reference):
And, unfortunately, many people use "Factory" to denote another kind of factory, that creates factory or factories (or their interfaces). Based on their theory:
Product implements IProduct, which is created by Factory, which implements IFactory, which is created by AbstractFactory.
To understand how silly this is, let's continue our equation:
AbstractFactory implements IAbstractFactory, which is created by... AbstractAbstractFactory???
I hope you see the point. Don't get confused, and please don't invent things that don't exist for reason.
-
P.S.: Factory for Products is AbstractFactory, and Factory for Abstract Factories would be just another example of AbstractFactory as well.
If you use numpy
, this is easy:
slice = arr[:2,:2]
or if you want the 0's,
slice = arr[0:2,0:2]
You'll get the same result.
*note that slice
is actually the name of a builtin-type. Generally, I would advise giving your object a different "name".
Another way, if you're working with lists of lists*:
slice = [arr[i][0:2] for i in range(0,2)]
(Note that the 0's here are unnecessary: [arr[i][:2] for i in range(2)]
would also work.).
What I did here is that I take each desired row 1 at a time (arr[i]
). I then slice the columns I want out of that row and add it to the list that I'm building.
If you naively try: arr[0:2]
You get the first 2 rows which if you then slice again arr[0:2][0:2]
, you're just slicing the first two rows over again.
*This actually works for numpy arrays too, but it will be slow compared to the "native" solution I posted above.
I also faced this issue, my pages getting 404. And then I added README.md on my repository, and the 404 was gone.
You can use int casting which allows the base specification.
int(b, 2) # Convert a binary string to a decimal int.
If you're using rails you can also use in_groups_of:
foo.in_groups_of(3)
For me it turned out to be an relative symbolic link (to the referenced project) that couldn't be used by grade. (I was referencing a library). Thats a pretty edgy edge-case but maybe it helps someone in the future.
I solved it by putting a absolute symbolic link.
Before ln -s ../library
after ln -s /the/full/path/to/the/library
As per your question, to solve this problem for Firefox and Opera using Aneesh Karthik C approach you need to add "float" right" attribute.
Check the example here. This CSS works in Firefox (26.0) , Opera (12.15), Chrome (32.0.1700) and Safari (7.0)
br {
content: " ";
float:right;
}
I hope this will answer your question!!

I think what you really want is an ArrayList or Vector. Arrays in Java are not like those in Javascript.
You could check whether the value of your selectOneMenu
component belongs to the list of subjects.
Namely:
public void subjectSelectionChanged() {
// Cancel if subject is manually written
if (!subjectList.contains(aktNachricht.subject)) { return; }
// Write your code here in case the user selected (or wrote) an item of the list
// ....
}
Supposedly subjectList
is a collection type, like ArrayList
. Of course here your code will run in case the user writes an item of your selectOneMenu
list.

git stash -u
Explanation: Stash local changes including untracked changes (-u
flag). The command saves your local modifications away and reverts the working directory to match the HEAD commit.
git stash pop
Explanation: The command will reapply the changes to the top of the current working tree state.
git stash drop
Explanation: The command will permanently remove the stashed entry
Take a look at Joda-Time (https://www.joda.org/joda-time/).
DateTimeFormatter parser = ISODateTimeFormat.date();
DateTime date = parser.parseDateTime(dateString);
String nextDay = parser.print(date.plusDays(1));
You had two options.
Option 1: simplest makefile = NO MAKEFILE.
Rename "a3driver.cpp" to "a3a.cpp", and then on the command line write:
nmake a3a.exe
And that's it. If you're using GNU Make, use "make" or "gmake" or whatever.
Option 2: a 2-line makefile.
a3a.exe: a3driver.obj
link /out:a3a.exe a3driver.obj
The <h:outputLink>
renders a fullworthy HTML <a>
element with the proper URL in the href
attribute which fires a bookmarkable GET request. It cannot directly invoke a managed bean action method.
<h:outputLink value="destination.xhtml">link text</h:outputLink>
The <h:commandLink>
renders a HTML <a>
element with an onclick
script which submits a (hidden) POST form and can invoke a managed bean action method. It's also required to be placed inside a <h:form>
.
<h:form>
<h:commandLink value="link text" action="destination" />
</h:form>
The ?faces-redirect=true
parameter on the <h:commandLink>
, which triggers a redirect after the POST (as per the Post-Redirect-Get pattern), only improves bookmarkability of the target page when the link is actually clicked (the URL won't be "one behind" anymore), but it doesn't change the href
of the <a>
element to be a fullworthy URL. It still remains #
.
<h:form>
<h:commandLink value="link text" action="destination?faces-redirect=true" />
</h:form>
Since JSF 2.0, there's also the <h:link>
which can take a view ID (a navigation case outcome) instead of an URL. It will generate a HTML <a>
element as well with the proper URL in href
.
<h:link value="link text" outcome="destination" />
So, if it's for pure and bookmarkable page-to-page navigation like the SO username link, then use <h:outputLink>
or <h:link>
. That's also better for SEO since bots usually doesn't cipher POST forms nor JS code. Also, UX will be improved as the pages are now bookmarkable and the URL is not "one behind" anymore.
When necessary, you can do the preprocessing job in the constructor or @PostConstruct
of a @RequestScoped
or @ViewScoped
@ManagedBean
which is attached to the destination page in question. You can make use of @ManagedProperty
or <f:viewParam>
to set GET parameters as bean properties.

I always supposed avg
is omitted from the builtins/stdlib because it is as simple as
sum(L)/len(L) # L is some list
and any caveats would be addressed in caller code for local usage already.
Notable caveats:
non-float result: in python2, 9/4 is 2. to resolve, use float(sum(L))/len(L)
or from __future__ import division
division by zero: the list may be empty. to resolve:
if not L:
raise WhateverYouWantError("foo")
avg = float(sum(L))/len(L)
Use:
<?php header('Location: another-php-file.php'); exit(); ?>
Or if you've already opened PHP tags, use this:
header('Location: another-php-file.php'); exit();
You can also redirect to external pages, e.g.:
header('Location: https://www.google.com'); exit();
Make sure you include exit()
or include die()

v-bind
and v-on
are two frequently used directives in vuejs html template.
So they provided a shorthand notation for the both of them as follows:
You can replace v-on:
with @
v-on:click='someFunction'
as:
@click='someFunction'
Another example:
v-on:keyup='someKeyUpFunction'
as:
@keyup='someKeyUpFunction'
Similarly, v-bind
with :
v-bind:href='var1'
Can be written as:
:href='var1'

First, {"value": .value} can be abbreviated to just {value}.
Second, the --argfile option (available in jq 1.4 and jq 1.5) may be of interest as it avoids having to use the --slurp option.
Putting these together, the two objects in the two files can be combined in the specified way as follows:
$ jq -n --argfile o1 file1 --argfile o2 file2 '$o1 * $o2 | {value}'
The '-n' flag tells jq not to read from stdin, since inputs are coming from the --argfile options here.
The jq manual deprecates --argfile
because its semantics are non-trivial: if the specified input file contains exactly one JSON entity, then that entity is read as is; otherwise, the items in the stream are wrapped in an array.
If you are uncomfortable using --argfile, there are several alternatives you may wish to consider. In doing so, be assured that using --slurpfile
does not incur the inefficiencies of the -s
command-line option when the latter is used with multiple files.
This is a late answer but hope this might help.
Scenario 1: You visited the site for first time and did not touch any field. The state of form is
ng-untouched and ng-pristine
Scenario 2: You are currently entering the values in a particular field in the form. Then the state is
ng-untouched and ng-dirty
Scenario 3: You are done with entering the values in the field and moved to next field
ng-touched and ng-dirty
Scenario 4: Say a form has a phone number field . You have entered the number but you have actually entered 9 digits but there are 10 digits required for a phone number.Then the state is ng-invalid
In short:
ng-untouched:When the form field has not been visited yet
ng-touched: When the form field is visited AND the field has lost focus
ng-pristine: The form field value is not changed
ng-dirty: The form field value is changed
ng-valid : When all validations of form fields are successful
ng-invalid: When all validations of form fields are not successful

In the course of developing an in-house address verification service at a German company I used to work for I've come across a number of ways to tackle this issue. I'll do my best to sum up my findings below:
Free, Open Source Software
Clearly, the first approach anyone would take is an open-source one (like openstreetmap.org), which is never a bad idea. But whether or not you can really put this to good and reliable use depends very much on how much you need to rely on the results.
Addresses are an incredibly variable thing. Verifying U.S. addresses is not an easy task, but bearable, but once you're going for Europe, especially the U.K. with their extensive Postal Code system, the open-source approach will simply lack data.
Web Services / APIs
Enterprise-Class Software
Money gets it done, obviously. But not every business or developer can spend ~$0.15 per address lookup (that's $150 for 1,000 API requests) - a very expensive business model the vast majority of address validation APIs have implemented.
What I ended up integrating: streetlayer API
Since I was not willing to take on the programmatic approach of verifying address data manually I finally came to the conclusion that I was in need of an API with a price tag that would not make my boss want to fire me and still deliver solid and reliable international verification results.
Long story short, I ended up integrating an API built by apilayer, called "streetlayer API". I was easily convinced by a simple JSON integration, surprisingly accurate validation results and their developer-friendly pricing. Also, 100 requests/month are entirely free.
Hope this helps!

If you use script to navigate to the page, use the open
method with the target _blank
to open a new window / tab:
<img src="..." alt="..." onclick="window.open('anotherpage.html', '_blank');" />
However, if you want search engines to find the page, you should just wrap the image in a regular link instead.
All DDL statements in Oracle PL/SQL should use Execute Immediate before the statement. Hence you should use:
execute immediate 'truncate table schema.tablename';
Using a
instead of w
should let you update the file instead of creating a new one/overwriting everything in the existing file.
See this answer for a difference in the modes.
It works for me:
<div class="text-center">
<ul class="pagination pagination-lg">
<li>
<a href="#" aria-label="Previous">
<span aria-hidden="true">«</span>
</a>
</li>
<li><a href="#">1</a></li>
<li><a href="#">2</a></li>
<li><a href="#">3</a></li>
<li><a href="#">4</a></li>
<li><a href="#">5</a></li>
<li>
<a href="#" aria-label="Next">
<span aria-hidden="true">»</span>
</a>
</li>
</ul>
Assuming alphanumeric words, you can use:
Search = ^([A-Za-z0-9]+)$
Replace = able:"\1"
Or, if you just want to highlight the lines and use "Replace All" & "In Selection" (with the same replace):
Search = ^(.+)$
^
points to the start of the line.
$
points to the end of the line.
\1
will be the source match within the parentheses.

If you go to your android-sdk/tools
folder I think you'll find a message :
The adb tool has moved to platform-tools/
If you don't see this directory in your SDK, launch the SDK and AVD Manager (execute the android tool) and install "Android SDK Platform-tools"
Please also update your PATH environment variable to include the platform-tools/ directory, so you can execute adb from any location.
So you should also add C:/android-sdk/platform-tools
to you environment path. Also after you modify the PATH
variable make sure that you start a new CommandPrompt
window.

If I remember correctly the XmlDocument.Load(string) method always assumes UTF-8, regardless of the XML encoding. You would have to create a StreamReader with the correct encoding and use that as the parameter.
xmlDoc.Load(new StreamReader(
File.Open("file.xml"),
Encoding.GetEncoding("iso-8859-15")));
I just stumbled across KB308061 from Microsoft. There's an interesting passage: Specify the encoding declaration in the XML declaration section of the XML document. For example, the following declaration indicates that the document is in UTF-16 Unicode encoding format:
<?xml version="1.0" encoding="UTF-16"?>
Note that this declaration only specifies the encoding format of an XML document and does not modify or control the actual encoding format of the data.

After searching a lot I find out that it is possible to create a new folder from the web interface, but it would require you to have at least one file within the folder when creating it.
When using the normal way of creating new files through the web interface, you can type in the folder into the file name to create the file within that new directory.
For example, if I would like to create the file filename.md
in a series of sub-folders, I can do this (taken from the GitHub blog):
OP asked for users connected to a particular database:
-- Who's currently connected to my_great_database?
SELECT * FROM pg_stat_activity
WHERE datname = 'my_great_database';
This gets you all sorts of juicy info (as others have mentioned) such as
usesysid
)usename
)appname
), if it bothers to set that variable -- psql
does :-)client_addr
)query

There is code and binaries available here for a console app that can export private keys marked as non-exportable, and it won't trigger antivirus apps like mimikatz will.
The code is based on a paper by the NCC Group.
will need to run the tool with the local system account, as it works by writing directly to memory used by Windows' lsass
process, in order to temporarily mark keys as exportable. This can be done using PsExec

You will not be able to find out the password he chose. However, you may create a new user or set a new password to the existing user.
Usually, you can login as the postgres user:
Open a Terminal and do sudo su postgres
.
Now, after entering your admin password, you are able to launch psql
and do
CREATE USER yourname WITH SUPERUSER PASSWORD 'yourpassword';
This creates a new admin user. If you want to list the existing users, you could also do
\du
to list all users and then
ALTER USER yourusername WITH PASSWORD 'yournewpass';
Try the following parameter:
-nc
,--no-clobber
: skip downloads that would download to existing files.
Sample usage:
wget -nc http://example.com/pic.png
For some reason, the above answer did not work for me; I did not return to the command prompt after running it as I expected with the trailing &. Instead, I simply tried with

I saw in getwindowtext (user32) on pinvoke.net that you can place a MarshalAs

I found a solution to solve this problem in Python.
go to c:\python27\ directory and rigtlcick python.exe and tab to compaitbility and select the admin privilege option and apply the changes. Now you issue the command it allows to create the socket connection.
One of the main differences between surfaceview and view is that to refresh the screen for a normal view we have to call invalidate method from the same thread where the view is defined. But even if we call invalidate, the refreshing does not happen immediately. It occurs only after the next arrival of the VSYNC signal. VSYNC signal is a kernel generated signal which happens every 16.6 ms or this is also known as 60 frame per second. So if we want more control over the refreshing of the screen (for example for very fast moving animation), we should not use normal view class.
On the other hand in case of surfaceview, we can refresh the screen as fast as we want and we can do it from a background thread. So refreshing of the surfaceview really does not depend upon VSYNC, and this is very useful if we want to do high speed animation. I have few training videos and example application which explain all these things nicely. Please have a look at the following training videos.
When you execute a method (i.e. function assigned to an object), inside it you can use this
variable to refer to this object, for example:
var obj = {_x000D_
someProperty: true,_x000D_
someMethod: function() {_x000D_
console.log(this.someProperty);_x000D_
}_x000D_
};_x000D_
obj.someMethod(); // logs true
_x000D_
If you assign a method from one object to another, its this
variable refers to the new object, for example:
var obj = {_x000D_
someProperty: true,_x000D_
someMethod: function() {_x000D_
console.log(this.someProperty);_x000D_
}_x000D_
};_x000D_
_x000D_
var anotherObj = {_x000D_
someProperty: false,_x000D_
someMethod: obj.someMethod_x000D_
};_x000D_
_x000D_
anotherObj.someMethod(); // logs false
_x000D_
The same thing happens when you assign requestAnimationFrame
method of window
to another object. Native functions, such as this, has build-in protection from executing it in other context.
There is a Function.prototype.call()
function, which allows you to call a function in another context. You just have to pass it (the object which will be used as context) as a first parameter to this method. For example alert.call({})
gives TypeError: Illegal invocation
. However, alert.call(window)
works fine, because now alert
is executed in its original scope.
If you use .call()
with your object like that:
support.animationFrame.call(window, function() {});
it works fine, because requestAnimationFrame
is executed in scope of window
instead of your object.
However, using .call()
every time you want to call this method, isn't very elegant solution. Instead, you can use Function.prototype.bind()
. It has similar effect to .call()
, but instead of calling the function, it creates a new function which will always be called in specified context. For example:
window.someProperty = true;_x000D_
var obj = {_x000D_
someProperty: false,_x000D_
someMethod: function() {_x000D_
console.log(this.someProperty);_x000D_
}_x000D_
};_x000D_
_x000D_
var someMethodInWindowContext = obj.someMethod.bind(window);_x000D_
someMethodInWindowContext(); // logs true
_x000D_
The only downside of Function.prototype.bind()
is that it's a part of ECMAScript 5, which is not supported in IE <= 8. Fortunately, there is a polyfill on MDN.
As you probably already figured out, you can use .bind()
to always execute requestAnimationFrame
in context of window
. Your code could look like this:
var support = {
animationFrame: (window.requestAnimationFrame ||
window.mozRequestAnimationFrame ||
window.webkitRequestAnimationFrame ||
window.msRequestAnimationFrame ||
window.oRequestAnimationFrame).bind(window)
};
Then you can simply use support.animationFrame(function() {});

[[]]*3

It's as if you'd said
a = []
listy = [a, a, a]
In other words, all three list references refer to the same list instance.
we solve this problem without using regex this query replace only exact match string.
update employee set
employee_firstname =
trim(REPLACE(concat(" ",employee_firstname," "),' jay ',' abc '))
Example:
emp_id employee_firstname
1 jay
2 jay ajay
3 jay
After executing query result:
emp_id employee_firstname
1 abc
2 abc ajay
3 abc
You have the syntax wrong; there is no need to place a period inside a double-quoted string. Instead, it should be more like
$query = mysql_query("SELECT * FROM table WHERE the_number LIKE '$prefix%'");
You can confirm this by printing out the string to see that it turns out identical to the first case.
Of course it's not a good idea to simply inject variables into the query string like this because of the danger of SQL injection. At the very least you should manually escape the contents of the variable with mysql_real_escape_string
, which would make it look perhaps like this:
$sql = sprintf("SELECT * FROM table WHERE the_number LIKE '%s%%'",
mysql_real_escape_string($prefix));
$query = mysql_query($sql);
Note that inside the first argument of sprintf
the percent sign needs to be doubled to end up appearing once in the result.

In this line ...
if (*message == "\0") {
... as you can see in the warning ...
warning: comparison between pointer and integer ('int' and 'char *')
... you are actually comparing an int

On a side note, if you'd like to compare strings you should use strcmp

Try getting Spring to inject it, assuming you're using Spring as a dependency-injection framework.
In your class, do something like this:
public void setSqlResource(Resource sqlResource) {
this.sqlResource = sqlResource;
}
And then in your application context file, in the bean definition, just set a property:
<bean id="someBean" class="...">
<property name="sqlResource" value="classpath:com/somecompany/sql/sql.txt" />
</bean>
And Spring should be clever enough to load up the file from the classpath and give it to your bean as a resource.
You could also look into PropertyPlaceholderConfigurer, and store all your SQL in property files and just inject each one separately where needed. There are lots of options.
Just to add to the other answers, I found that the simplest solution to achieve the rounded corners was to set the following as a background to your Edittext.
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android">
<solid android:color="@android:color/white"/>
<corners android:radius="8dp"/>
</shape>
Move the -h and specify that mydir is a directory
attrib /S /D /L -H mydir\*.*
//Get
var p = $("#elementId");
var offset = p.offset();
//set
$("#secondElementId").offset({ top: offset.top, left: offset.left});
Ok, finally found the solution.
Probably due to lack of experience with ReactJS and web development...
var Task = React.createClass({
render: function() {
var percentage = this.props.children + '%';
....
<div className="ui-progressbar-value ui-widget-header ui-corner-left" style={{width : percentage}}/>
...
I created the percentage variable outside in the render function.

finished with the virtualenv.
Check that your virtualenv includes django. a virtualenv by default
has no modules installed. you either have to install django in your
virtualenv (even if you have it in your machine already) or use
virtualenv --system-site-packages
when creating a virtualenv to
include system site packages in the virtualenv.
Add django to your path. open python, import django
, then run
django
to see django's path. then add it to your ~/.bashrc
(or
~/.zshrc
if you're using zsh
). more info in here
Install django-admin

Make the value of first item of selection box to blank.
So when every you post the FORM you get blank value and using this way you would know that user hasn't selected anything from dropdown.
<select name="user_role" required>
<option value="">-Select-</option>
<option value="User">User</option>
<option value="Admin">Admin</option>
</select>
trigger('submit') does not work.beacuse onSubmit method does not get fired. the following code works for me, call onSubmit method when using this code :
$("form").find(':submit').click();
my case was a little different - unintentionally I have changed owner of git repository (project.git directory in my case), changing owner back to the git user helped
AF_INET = Address Format, Internet = IP Addresses
PF_INET = Packet Format, Internet = IP, TCP/IP or UDP/IP
AF_INET is the address family that is used for the socket you're creating (in this case an Internet Protocol address). The Linux kernel, for example, supports 29 other address families such as UNIX sockets and IPX, and also communications with IRDA and Bluetooth (AF_IRDA and AF_BLUETOOTH, but it is doubtful you'll use these at such a low level).
For the most part sticking with AF_INET for socket programming over a network is the safest option.
Meaning, AF_INET refers to addresses from the internet, IP addresses specifically.
PF_INET refers to anything in the protocol, usually sockets/ports.

You are getting NullReferenceExeption
because of you are using the cmb.SelectedValue
which is null. the comboBox
doesn't know what is the value of your custom class ComboboxItem
, so either do:
ComboboxItem selectedCar = (ComboboxItem)comboBox2.SelectedItem;
int selecteVal = Convert.ToInt32(selectedCar.Value);
Or better of is use data binding like:
ComboboxItem item1 = new ComboboxItem();
item1.Text = "test";
item1.Value = "123";
ComboboxItem item2 = new ComboboxItem();
item2.Text = "test2";
item2.Value = "456";
List<ComboboxItem> items = new List<ComboboxItem> { item1, item2 };
this.comboBox1.DisplayMember = "Text";
this.comboBox1.ValueMember = "Value";
this.comboBox1.DataSource = items;
mod_log_forensic is what you want, but it may not be included/available with your Apache install by default.

To read the memory at given addresses you should take a look at x
x/x $esp
for hex x/d $esp
for signed x/u $esp
for unsigned etc. x uses the format syntax, you could also take a look at the current instruction via x/i $eip
etc.
Considering that the UrnMapping
class is mapped to the internal_uddi
table, I would suggest this:
@Repository
public interface UrnMappingRepository extends JpaRepository<UrnMapping, Long> {
@Query(value = "select iu from UrnMapping iu where iu.urn like %:text% or iu.contact like %:text%")
Page<UrnMapping> fullTextSearch(@Param("text") String text, Pageable pageable);
}
Please note that you might have to turn off native queries with dynamic requests.
Promises are an abstraction over statements that allow us to express ourselves synchronously with asynchronous code. They represent a execution of a one time task.
They also provide exception handling, just like normal code, you can return from a promise or you can throw.
What you'd want in synchronous code is:
try{
try{
var res = $http.getSync("url");
res = someProcessingOf(res);
} catch (e) {
console.log("Got an error!",e);
throw e; // rethrow to not marked as handled
}
// do more stuff with res
} catch (e){
// handle errors in processing or in error.
}
The promisified version is very similar:
$http.get("url").
then(someProcessingOf).
catch(function(e){
console.log("got an error in initial processing",e);
throw e; // rethrow to not marked as handled,
// in $q it's better to `return $q.reject(e)` here
}).then(function(res){
// do more stuff
}).catch(function(e){
// handle errors in processing or in error.
});
No, you will have to use OR
to combine your LIKE
statements:
SELECT
*
FROM
table
WHERE
column LIKE 'Text%' OR
column LIKE 'Link%' OR
column LIKE 'Hello%' OR
column LIKE '%World%'

Yes, for scalar values, a combination of implode and array_slice will do:
$bar = implode(array_slice($array, 0, 1));
$bin = implode(array_slice($array, 1, 1));
$ipsum = implode(array_slice($array, 2, 1));
Or mix it up with array_values
and list
(thanks @nikic) so that it works with all types of values:
list($bar) = array_values(array_slice($array, 0, 1));
In case if you have to apply your custom class you can use
@Html.TextBoxFor(m => m.Birthday, new Dictionary<string, object>() { {"readonly", "true"}, {"class", "commonField"} } )
Where are
commonField is CSS class
and Birthday could be string field that you probably can use to keep jQuery Datapicker
date :)
<script>
$(function () {
$("#Birthday").datepicker({
});
});
</script>
That's a real life example.
Actually one can always create an ordinary list of numpy arrays and convert it later.
In [1]: import numpy as np
In [2]: a = np.array([[1,2],[3,4]])
In [3]: b = np.array([[1,2],[3,4]])
In [4]: l = [a]
In [5]: l.append(b)
In [6]: l = np.array(l)
In [7]: l.shape
Out[7]: (2, 2, 2)
In [8]: l
Out[8]:
array([[[1, 2],
[3, 4]],
[[1, 2],
[3, 4]]])
Users who have one of the 3 countries
SELECT DISTINCT user_id
FROM table
WHERE ancestry IN('England','France','Germany')
Users who have all 3 countries
SELECT DISTINCT A.userID
FROM table A
INNER JOIN table B on A.user_id = B.user_id
INNER JOIN table C on A.user_id = C.user_id
WHERE A.ancestry = 'England'
AND B.ancestry = 'Germany'
AND C.ancestry = 'France'
range()
can only work with integers, but dividing with the /
operator always results in a float value:
>>> 450 / 10
45.0
>>> range(450 / 10)
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
TypeError: 'float' object cannot be interpreted as an integer
Make the value an integer again:
for i in range(int(c / 10)):
or use the //
floor division operator:
for i in range(c // 10):
touchstart or touchend are not good, because if you scroll the page, the device do stuff. So, if I want close a window with tap or click outside the element, and scroll the window, I've done:
$(document).on('touchstart', function() {
documentClick = true;
});
$(document).on('touchmove', function() {
documentClick = false;
});
$(document).on('click touchend', function(event) {
if (event.type == "click") documentClick = true;
if (documentClick){
doStuff();
}
});
I used the following:
delta = timedelta()
totalMinute, second = divmod(delta.seconds, 60)
hour, minute = divmod(totalMinute, 60)
print(f"{hour}h{minute:02}m{second:02}s")
You can create your own custom selector :hasValue
and then use that to find, filter, or test any other jQuery elements.
jQuery.expr[':'].hasValue = function(el,index,match) {
return el.value != "";
};
Then you can find elements like this:
var data = $("form input:hasValue").serialize();
Or test the current element with .is()
var elHasValue = $("#name").is(":hasValue");
jQuery.expr[':'].hasValue = function(el) {_x000D_
return el.value != "";_x000D_
};_x000D_
_x000D_
_x000D_
var data = $("form input:hasValue").serialize();_x000D_
console.log(data)_x000D_
_x000D_
_x000D_
var elHasValue = $("[name='LastName']").is(":hasValue");_x000D_
console.log(elHasValue)
_x000D_

You can't manipulate :after
, because it's not technically part of the DOM and therefore is inaccessible by any JavaScript. But you can add a new class with a new :after
specified.
CSS:
.pageMenu .active.changed:after {
/* this selector is more specific, so it takes precedence over the other :after */
border-top-width: 22px;
border-left-width: 22px;
border-right-width: 22px;
}
JS:
$('.pageMenu .active').toggleClass('changed');
UPDATE: while it's impossible to directly modify the :after
content, there are ways to read and/or override it using JavaScript. See "Manipulating CSS pseudo-elements using jQuery (e.g. :before and :after)" for a comprehensive list of techniques.
Create a git clone of that includes your Subversion trunk, tags, and branches with
git svn clone http://svn.example.com/project -T trunk -b branches -t tags
The --stdlayout
option is a nice shortcut if your Subversion repository uses the typical structure:
git svn clone http://svn.example.com/project --stdlayout
Make your git repository ignore everything the subversion repo does:
git svn show-ignore >> .git/info/exclude
You should now be able to see all the Subversion branches on the git side:
git branch -r
Say the name of the branch in Subversion is waldo
. On the git side, you'd run
git checkout -b waldo-svn remotes/waldo
The -svn suffix is to avoid warnings of the form
warning: refname 'waldo' is ambiguous.
To update the git branch waldo-svn
, run
git checkout waldo-svn git svn rebase
To add a Subversion branch to a trunk-only clone, modify your git repository's .git/config
to contain
[svn-remote "svn-mybranch"] url = http://svn.example.com/project/branches/mybranch fetch = :refs/remotes/mybranch
You'll need to develop the habit of running
git svn fetch --fetch-all
to update all of what git svn
thinks are separate remotes. At this point, you can create and track branches as above. For example, to create a git branch that corresponds to mybranch, run
git checkout -b mybranch-svn remotes/mybranch
For the branches from which you intend to git svn dcommit
, keep their histories linear!
You may also be interested in reading an answer to a related question.
If you're really desperate, do a dump of the repo (look at "svnadmin dump") and then grep through it. It's not pretty, but you can look around the search results to find the metadata that indicates the file and revision, then check it out for a better look.
Not a good solution, to be sure, but it is free :) SVN provides no feature for searching past checkins (or even past log files, AFAIK).
Apart from the security settings, I had to open some ports on both servers for the transaction to run. I had to open port 59640 but according to the following suggestion, port 135 has to be open. http://support.microsoft.com/kb/839279
Doxygen or Sandcastle help file builder are the primary tools that will extract XML documentation into HTML (and other forms) of external documentation.
Note that you can combine these documentation exporters with documentation generators - as you've discovered, Resharper has some rudimentary helpers, but there are also much more advanced tools to do this specific task, such as GhostDoc (for C#/VB code with XML documentation) or my addin Atomineer Pro Documentation (for C#, C++/CLI, C++, C, VB, Java, JavaScript, TypeScript, JScript, PHP, Unrealscript code containing XML, Doxygen, JavaDoc or Qt documentation).
I recently used this to read all the lines from a file:
alist = open('maze.txt').read().split()
or you can use this for that little bit of extra added safety:
with f as open('maze.txt'):
alist = f.read().split()
It doesn't work with whitespace in-between text in a single line, but it looks like your example file might not have whitespace splitting the values. It is a simple solution and it returns an accurate list of values, and does not add an empty string: ''
for every empty line, such as a newline at the end of the file.

For some people, the accepted answer is not working, I found this other answer and it is working for me: How can I pass a parameter to a setTimeout() callback?
var hello = "Hello World";
setTimeout(alert, 1000, hello);
'hello' is the parameter being passed, you can pass all the parameters after the timeout time. Thanks to @Fabio Phms for the answer.
It sounds like they are behind a web application firewall. Take a look at modsecurity and OWASP to see how those work.
In reality, what you are asking is how to do bot detection evasion. That is not what Selenium WebDriver is for. It is for testing your web application not hitting other web applications. It is possible, but basically, you'd have to look at what a WAF looks for in their rule set and specifically avoid it with selenium if you can. Even then, it might still not work because you don't know what WAF they are using.
You did the right first step, that is, faking the user agent. If that didn't work though, then a WAF is in place and you probably need to get more tricky.
Point taken from other answer. Make sure your user agent is actually being set correctly first. Maybe have it hit a local web server or sniff the traffic going out.

However, as others have mentioned, MySQL does not support this command. WITH was added in SQL:1999; the newest version of the SQL standard is SQL:2008. You can find some more information about databases that support SQL:1999's various features on Wikipedia.
MySQL has traditionally lagged a bit in support for the SQL standard, whereas commercial databases like Oracle, SQL Server (recently), and DB2 have followed them a bit more closely. PostgreSQL is typically pretty standards compliant as well.
You may want to look at MySQL's roadmap; I'm not completely sure when this feature might be supported, but it's great for creating readable roll-up queries.
The DataTable has a collection .Rows
of DataRow elements.
Each DataRow corresponds to one row in your database, and contains a collection of columns.
In order to access a single value, do something like this:
foreach(DataRow row in YourDataTable.Rows)
{
string name = row["name"].ToString();
string description = row["description"].ToString();
string icoFileName = row["iconFile"].ToString();
string installScript = row["installScript"].ToString();
}

I am using git push <remote-name> tag <tag-name>
to ensure that I am pushing a tag. I use it like: git push origin tag v1.0.1
. This pattern is based upon the documentation (man git-push
):

...
<refspec>...
...
tag <tag> means the same as refs/tags/<tag>:refs/tags/<tag>.
I suggest:
=not(isblank(A1))
which returns TRUE if A1 is populated and FALSE otherwise. Which compares with:
=isblank(A1)
which returns TRUE if A1 is empty and otherwise FALSE.

This is different than your stated algorithm of producing a parallel array with zero values, but it is a more Perly way of doing it...
If you must have a parallel array that is the same size as your first array with the elements initialized to 0, this statement will dynamically do it: @array=(0) x scalar(@other_array);
but really, you don't need to do that.

If you are not worried about an unbounded queue of Callable/Runnable tasks, you can use one of them. As suggested by bruno, I too prefer newFixedThreadPool
to newCachedThreadPool
over these two.
But ThreadPoolExecutor provides more flexible features compared to either newFixedThreadPool
or newCachedThreadPool
ThreadPoolExecutor(int corePoolSize, int maximumPoolSize, long keepAliveTime,
TimeUnit unit, BlockingQueue<Runnable> workQueue, ThreadFactory threadFactory,
RejectedExecutionHandler handler)
Advantages:
You have full control of BlockingQueue size. It's not un-bounded, unlike the earlier two options. I won't get an out of memory error due to a huge pile-up of pending Callable/Runnable tasks when there is unexpected turbulence in the system.
You can implement custom Rejection handling policy OR use one of the policies:
In the default ThreadPoolExecutor.AbortPolicy
, the handler throws a runtime RejectedExecutionException upon rejection.
In ThreadPoolExecutor.CallerRunsPolicy
, the thread that invokes execute itself runs the task. This provides a simple feedback control mechanism that will slow down the rate that new tasks are submitted.
In ThreadPoolExecutor.DiscardPolicy
, a task that cannot be executed is simply dropped.
In ThreadPoolExecutor.DiscardOldestPolicy
, if the executor is not shut down, the task at the head of the work queue is dropped, and then execution is retried (which can fail again, causing this to be repeated.)
You can implement a custom Thread factory for the below use cases:
