If performance is an issue, you should consider using StringTokenizer
instead of split
. StringTokenizer
is much much faster than split
, even though it is a "legacy" class (but not deprecated).
I imagine that there are not many browsers supporting extension. Indeed, I have been interested in this question for the last year and I only found Dolphin supporting add-ons and other cool features announced few days ago. I want to test it soon.
::
is used in static context, ie. when some method or property is declared as static:
class Math {
public static function sin($angle) {
return ...;
}
}
$result = Math::sin(123);
Also, the ::
operator (the Scope Resolution Operator, a.k.a Paamayim Nekudotayim) is used in dynamic context when you invoke a method/property of a parent class:
class Rectangle {
protected $x, $y;
public function __construct($x, $y) {
$this->x = $x;
$this->y = $y;
}
}
class Square extends Rectangle {
public function __construct($x) {
parent::__construct($x, $x);
}
}
->
is used in dynamic context, ie. when you deal with some instance of some class:
class Hello {
public function say() {
echo 'hello!';
}
}
$h = new Hello();
$h->say();
By the way: I don't think that using Symfony is a good idea when you don't have any OOP experience.
To achieve what you are looking for you can use the viewport-percentage length vw
.
Here is a quick example I made on jsfiddle.
HTML:
<div class="square">
<h1>This is a Square</h1>
</div>
CSS:
.square {
background: #000;
width: 50vw;
height: 50vw;
}
.square h1 {
color: #fff;
}
I am sure there are many other ways to do this but this way seemed the best to me.
This might be due to a security check. This thread might help you.
There are two suggestions: one with pushd and one with a registry change. I'd suggest to use the first one...
You can use this in a header file.
// setup session enviroment
ini_set('session.cookie_httponly',1);
ini_set('session.use_only_cookies',1);
This way all future session cookies will use httponly.
I suspect you haven't set up last_name
properly in the caller.
With the statement Worksheets(data_sheet).Range("C2").Value = ProcessString(last_name)
this will only work if last_name
is a string, i.e.
Dim last_name as String
appears in the caller somewhere.
The reason for this is that VBA passes in variables by reference by default which means that the data types have to match exactly between caller and callee.
1) Force ByVal -- Change your function to pass variable ByVal: Public Function ProcessString(ByVal input_string As String) As String
, or
2) Dim varname -- put Dim last_name As String
in the caller before you use it.
(1) works because for ByVal
, a copy of input_string is taken when passing to the function which will coerce it into the correct data type. It also leads to better program stability since the function cannot modify the variable in the caller.
If you need some es6 improvements not supported by Typescript, you can target es6 in your tsconfig and use Babel to convert your files in es5.
What I really don't understand with this kind of problem is that the html page I ran as a local file displayed perfectly in Chromium browser, but as soon as I uploaded it to my website, it produced this error.
Even stranger, it displayed perfectly in the Vivaldi browser whether displayed from the local or remote file.
Is this something to do with the way Chromium reads the character set? But why only with a remote file?
I fixed the problem by retyping the text in a simple text editor and making sure the single quote mark was the one I used.
You can try this:
<div ng-app="app">
<div ng-controller="AppCtrl">
<a my-dir ng-repeat="user in users" ng-click="fxn()">{{user.name}}</a>
</div>
</div>
<script>
var app = angular.module('app', []);
function AppCtrl($scope) {
$scope.users = [{ name: 'John', id: 1 }, { name: 'anonymous' }];
$scope.fxn = function () {
alert('It works');
};
}
app.directive("myDir", function ($compile) {
return {
scope: {ngClick: '='}
};
});
</script>
If the component is an EJB, then, there shouldn't be a problem injecting an EM.
But....In JBoss 5, the JAX-RS integration isn't great. If you have an EJB, you cannot use scanning and you must manually list in the context-param resteasy.jndi.resource. If you still have scanning on, Resteasy will scan for the resource class and register it as a vanilla JAX-RS service and handle the lifecycle.
This is probably the problem.
Don't put a name for target window when you use window.open("","NAME",....)
If you do it you can only open it once. Use _blank, etc instead of.
In Laravel 5.6, assuming the name of your subfolder' is Api
:
In your controller, you need these two lines:
namespace App\Http\Controllers\Api;
use App\Http\Controllers\Controller;
And in your route file api.php
, you need:
Route::resource('/myapi', 'Api\MyController');
You could just use glob
with recursive = true
, the pattern **
will match any files and zero or more directories, subdirectories and symbolic links to directories.
import glob, os
os.chdir("C:\\Users\\username\\Desktop\\MAIN_DIRECTORY")
for file in glob.glob("*/.csv", recursive = true):
print(file)
In NetBeans IDE 8.0 you can use a community contributed plugin https://github.com/tusharvjoshi/nbrunwithargs which will allow you to pass arguments while Run Project or Run Single File command.
For passing arguments to Run Project command either you have to set the arguments in the Project properties Run panel, or use the new command available after installing the plugin which says Run with Arguments
For passing command line arguments to a Java file having main method, just right click on the method and choose Run with Arguments command, of this plugin
UPDATE (24 mar 2014) This plugin is now available in NetBeans Plugin Portal that means it can be installed from Plugins dialog box from the available plugins shown from community contributed plugins, in NetBeans IDE 8.0
Foreach-object operation statement:

You can use a for loop with window.scrollTo and setTimeout to scroll smoothly with plain Javascript. To scroll to an element with my scrollToSmoothly
function: scrollToSmoothly(elem.offsetTop)
(assuming elem
is a DOM element). You can use this to scroll smoothly to any y-position in the document.
function scrollToSmoothly(pos, time){
/*Time is only applicable for scrolling upwards*/
/*Code written by hev1*/
/*pos is the y-position to scroll to (in pixels)*/
if(isNaN(pos)){
throw "Position must be a number";
}
if(pos<0){
throw "Position can not be negative";
}
var currentPos = window.scrollY||window.screenTop;
if(currentPos<pos){
var t = 10;
for(let i = currentPos; i <= pos; i+=10){
t+=10;
setTimeout(function(){
window.scrollTo(0, i);
}, t/2);
}
} else {
time = time || 2;
var i = currentPos;
var x;
x = setInterval(function(){
window.scrollTo(0, i);
i -= 10;
if(i<=pos){
clearInterval(x);
}
}, time);
}
}

don't return values and function
s don't have side effects.
Sometimes you want both side effect and return value.
This is easy to be done once you know that VBA passes arguments by default by reference so you can write your code in this way:
Sub getValue(retValue as Long)
...
retValue = 42
End SUb
Sub Main()
Dim retValue As Long
getValue retValue
...
End SUb
I was facing a problem like this, and had the idea of simply changing the innerHTML of the problematic object's children.
adiv.innerHTML = "<div...> the original html that js uses </div>";
Seems dirty, but it saved my life, as it works!
exec sp_lock
This query should give you existing locks.
exec sp_who SPID -- will give you some info
Having spids, you could check activity monitor(processes tab) to find out what processes are locking the tables ("details" for more info and "kill process" to kill it).
These two attributes are commonly confused:
android:gravity
sets the gravity of the content of the View it's
used on. android:layout_gravity
sets the gravity of the View or
Layout relative to its parent.So either put android:gravity="center"
on the parent or android:layout_gravity="center"
on the LinearLayout itself.
I have caught myself a number of times mixing them up and wondering why things weren't centering properly...

The Provider piece must be Provider=Microsoft.ACE.OLEDB.12.0
if your target database is ACCDB format. Provider=Microsoft.Jet.OLEDB.4.0
only works for the older MDB format.
You shouldn't even need Access installed if you're running 32 bit Windows. Jet 4 is included as part of the operating system. If you're using 64 bit Windows, Jet 4 is not included, but you still wouldn't need Access itself installed. You can install the Microsoft Access Database Engine 2010 Redistributable. Make sure to download the matching version (AccessDatabaseEngine.exe for 32 bit Windows, or AccessDatabaseEngine_x64.exe for 64 bit).
You can avoid the issue about which ADO version reference by using late binding, which doesn't require any reference.
Dim conn As Object
Set conn = CreateObject("ADODB.Connection")
Then assign your ConnectionString property to the conn object. Here is a quick example which runs from a code module in Excel 2003 and displays a message box with the row count for MyTable. It uses late binding for the ADO connection and recordset objects, so doesn't require setting a reference.
Public Sub foo()
Dim cn As Object
Dim rs As Object
Dim strSql As String
Dim strConnection As String
Set cn = CreateObject("ADODB.Connection")
strConnection = "Provider=Microsoft.Jet.OLEDB.4.0;" & _
"Data Source=C:\Access\webforums\whiteboard2003.mdb"
strSql = "SELECT Count(*) FROM MyTable;"
cn.Open strConnection
Set rs = cn.Execute(strSql)
MsgBox rs.fields(0) & " rows in MyTable"
rs.Close
Set rs = Nothing
cn.Close
Set cn = Nothing
End Sub
If this answer doesn't resolve the problem, edit your question to show us the full connection string you're trying to use and the exact error message you get in response for that connection string.
After some googling, I found the advice to do the following, and it worked:
SQL> startup mount
ORACLE Instance started
SQL> recover database
Media recovery complete
SQL> alter database open;

It entirely depends upon the Certificate Authority who issuing a certificate.
As far as Let's Encrypt CA, they wont issue TLS certificate on public IP address. https://community.letsencrypt.org/t/certificate-for-public-ip-without-domain-name/6082
To know your Certificate authority , you can execute following command and look for an entry marked below.
curl -v -u <username>:<password> "https://IPaddress/.."
What? From 2010 and nobody mentioned Ruby has a fine for /in loop (it's just nobody uses it):

Actually there are 3 places where gradle.properties
can be placed:
GRADLE_USER_HOME
environment variable, which if not set defaults to USER_HOME/.gradlemyProject2
in your case)myProject
)Gradle looks for gradle.properties
in all these places while giving precedence to properties definition based on the order above. So for example, for a property defined in gradle user home directory (#1) and the sub-project (#2) its value will be taken from gradle user home directory (#1).
You can find more details about it in gradle documentation here.
For newer Android platforms, one can execute a system utility screencap
in /system/bin
to get the screenshot without root permission.
You can try /system/bin/screencap -h
to see how to use it under adb or any shell.
By the way, I think this method is only good for single snapshot. If we want to capture multiple frames for screen play, it will be too slow. I don't know if there exists any other approach for a faster screen capture.
Try this. It uses the split
function which is a core part of javascript, nothing to do with jQuery.
var parts = html.split(":-"),
i, l
;
for (i = 0, l = parts.length; i < l; i += 2) {
$("#" + parts[i]).text(parts[i + 1]);
}
Here are 4 ways to insert data into a table.
Simple insertion when the table column sequence is known.
INSERT INTO Table1 VALUES (1,2,...)
Simple insertion into specified columns of the table.
INSERT INTO Table1(col2,col4) VALUES (1,2)
Bulk insertion when...
INSERT INTO Table1 {Column sequence} SELECT * FROM Table2
Bulk insertion of selected data into specified columns of Table2.
.
INSERT INTO Table1 (Column1,Column2 ....)
SELECT Column1,Column2...
FROM Table2
If you say window.location.reload(true)
the browser will skip the cache and reload the page from the server. window.location.reload(false)
will do the opposite.
Note: default
value for window.location.reload()
is false
import logging
# Only show warnings
logging.getLogger("urllib3").setLevel(logging.WARNING)
# Disable all child loggers of urllib3, e.g. urllib3.connectionpool
logging.getLogger("urllib3").propagate = False
It seems that Luiggi Mendoza
and joey rohan
both already answered this, but I think it can be clarified a little.
You can write it as a single if
statement:
if (inventory.contains("bread") && !inventory.contains("water")) {
// do something
}
In addition to Chris B's answer, if you need to use echo
anyway, still want to keep it simple and structured and don't want to spam the code with <?php stuff; ?>
's, you can use the syntax below.
For example you want to display the images of a gallery:
foreach($images as $image)
{
echo
'<li>',
'<a href="', site_url(), 'images/', $image['name'], '">',
'<img ',
'class="image" ',
'title="', $image['title'], '" ',
'src="', site_url(), 'images/thumbs/', $image['filename'], '" ',
'alt="', $image['description'], '"',
'>',
'</a>',
'</li>';
}
Echo takes multiple parameters so with good indenting it looks pretty good. Also using echo
with parameters is more effective than concatenating.
You can also do git push -u origin $(current_branch)
The following should work with the latest version of Apache common codec
byte[] decodedBytes = Base64.getDecoder().decode("YWJjZGVmZw==");
System.out.println(new String(decodedBytes));
and for encoding
byte[] encodedBytes = Base64.getEncoder().encode(decodedBytes);
System.out.println(new String(encodedBytes));
question is not clear, but what i understand you need to select a catagory that has name attribute and should have child author with value specified , correct me if i am worng
here is a xpath
//category[@name='Required value'][./author[contains(.,'Required value')]]
e.g
//category[@name='Sport'][./author[contains(.,'James Small')]]
I was facing the same problem under Windows7. The error message looks like that:
Fatal Python error: Py_Initialize: unable to load the file system codec ModuleNotFoundError: No module named 'encodings' Current thread 0x000011f4 (most recent call first):
I have installed python 2.7(uninstalled now), and I checked "Add Python to environment variables in Advanced Options" while installing python 3.6. It comes out that the Environment Variable "PYTHONHOME" and "PYTHONPATH" is still python2.7.
Finally I solved it by modify "PYTHONHOME" to python3.6 install path and remove variable "PYTHONPATH".
The quick possible answer: When you first successfully clone an empty git repository, the origin has no master branch. So the first time you have a commit to push you must do:
git push origin master
Which will create this new master branch for you. Little things like this are very confusing with git.
If this didn't fix your issue then it's probably a gitolite-related issue:
Your conf file looks strange. There should have been an example conf file that came with your gitolite. Mine looks like this:
repo phonegap
RW+ = myusername otherusername
repo gitolite-admin
RW+ = myusername
Please make sure you're setting your conf file correctly.
Gitolite actually replaces the gitolite user's account with a modified shell that doesn't accept interactive terminal sessions. You can see if gitolite is working by trying to ssh into your box using the gitolite user account. If it knows who you are it will say something like "Hi XYZ, you have access to the following repositories: X, Y, Z" and then close the connection. If it doesn't know you, it will just close the connection.
Lastly, after your first git push failed on your local machine you should never resort to creating the repo manually on the server. We need to know why your git push failed initially. You can cause yourself and gitolite more confusion when you don't use gitolite exclusively once you've set it up.
See this implementation from PEP318, implementing the singleton pattern with a decorator:

step-1) On Notepad++ Toolbar:
Plugins -> Plugin Manager -> Show Plugin Manager -> Available . Then select the Explorer. And click Install.
(Note: As in above comments some people like SherloXplorer. Pls, note that this requires .Net v2 )
step-2) Again on Notepad++ Toolbar:
Explorer->Explorer
Now you can view files with tree view.
Update: After adding Explorer, right click to edit a file in Notepad++ may stop working. To make it work again, restart Notepad++ afresh.
It will append \n

I had stumbled upon a similar issue recently. I am working in Visual Studio 2015 with Resharper Ultimate 2016.1.2. I was trying to add a new class to my code base while trying to reference a class from another assembly but Resharper would throw an error for that package.
With some help of a co-worker, I figured out that the referenced class existed in the global namespace and wasn't accessible from the new class since it was hidden by another entity of same name that existed in current namespace.
Adding a 'global::' keyword before the required namespace helped me to reference the class I was actually looking for. More details on this can be found on the page listed below:
just convert denominator to decimal before division e.g
select col1 / CONVERT(decimal(4,2), col2) from tbl1
It was asked about 4 years ago... but anyway, maybe the answer will be useful to someone here:
I do it like this in all the projects. First, I create a base class which contains a few helper methods like this:
public class BaseRepository
{
protected T QueryFirstOrDefault<T>(string sql, object parameters = null)
{
using (var connection = CreateConnection())
{
return connection.QueryFirstOrDefault<T>(sql, parameters);
}
}
protected List<T> Query<T>(string sql, object parameters = null)
{
using (var connection = CreateConnection())
{
return connection.Query<T>(sql, parameters).ToList();
}
}
protected int Execute(string sql, object parameters = null)
{
using (var connection = CreateConnection())
{
return connection.Execute(sql, parameters);
}
}
// Other Helpers...
private IDbConnection CreateConnection()
{
var connection = new SqlConnection(...);
// Properly initialize your connection here.
return connection;
}
}
And having such a base class I can easily create real repositories without any boilerplate code:
public class AccountsRepository : BaseRepository
{
public Account GetById(int id)
{
return QueryFirstOrDefault<Account>("SELECT * FROM Accounts WHERE Id = @Id", new { id });
}
public List<Account> GetAll()
{
return Query<Account>("SELECT * FROM Accounts ORDER BY Name");
}
// Other methods...
}
So all the code related to Dapper, SqlConnection-s and other database access stuff is located in one place (BaseRepository). All real repositories are clean and simple 1-line methods.
I hope it will help someone.
There is a package that converts it for you and returns the svg as a string to implement into your reactJS file.
The problem may be caused by the order of operation. If you modified the .gitignore first, then git rm --cached xxx,you may have to continue to encounter this problem.
Correct solution:
Order invariant!
The .gitignore reload after modification!
If you want to pre-subscribe to the same Observable which will be returned, just use
.do():
function getValueFromObservable() {
return this.store.do(
(data:any) => {
console.log("Line 1: " +data);
}
);
}
getValueFromObservable().subscribe(
(data:any) => {
console.log("Line 2: " +data)
}
);
I found this answer when I was getting a similar error for nodeName
after upgrading to Bootstrap 4. The issue was that the tabs didn't have the nav
and nav-tab
classes; adding those to the <ul>
element fixed the issue.
The problem is that you're displaying time()
, which is a UNIX timestamp based on GMT/UTC. That’s why it doesn’t change. date()
on the other hand, formats the time based on that timestamp.
A timestamp is the number of seconds since the Unix Epoch (January 1 1970 00:00:00 GMT).
echo date('Y-m-d H:i:s T', time()) . "<br>\n";
date_default_timezone_set('UTC');
echo date('Y-m-d H:i:s T', time()) . "<br>\n";
There are a few base64 encoders online to help you with this, this is probably the best I've seen:
http://www.greywyvern.com/code/php/binary2base64
As that page shows your main options for this are CSS:
div.image {
width:100px;
height:100px;
background-image:url(data:image/png;base64,iVBORwA<MoreBase64SringHere>);
}
Or the <img>
tag itself, like this:
<img alt="My Image" src="data:image/png;base64,iVBORwA<MoreBase64SringHere>" />
There are very good answers in this thread, but meanwhile many of them are outdated. Using git-filter-branch
is no longer recommended, because it is difficult to use and awfully slow on big repositories.
git-filter-repo
is much faster and simpler to use.
git-filter-repo
is a Python script, available at github: https://github.com/newren/git-filter-repo . When installed it looks like a regular git command and can be called by git filter-repo
.
You need only one file: the Python3 script git-filter-repo. Copy it to a path that is included in the PATH variable. On Windows you may have to change the first line of the script (refer INSTALL.md). You need Python3 installed installed on your system, but this is not a big deal.
First you can run
git filter-repo --analyze
This helps you to determine what to do next.
You can delete your DVD-rip file everywhere:
git filter-repo --invert-paths --path-match DVD-rip
Filter-repo is really fast. A task that took around 9 hours on my computer by filter-branch, was completed in 4 minutes by filter-repo. You can do many more nice things with filter-repo. Refer to the documentation for that.
Warning: Do this on a copy of your repository. Many actions of filter-repo cannot be undone. filter-repo will change the commit hashes of all modified commits (of course) and all their descendants down to the last commits!
If you are doing this simply because you want the Child to provide a re-usable trait to its parents, then you might consider doing that using render-props instead.
That technique actually turns the structure upside down. The Child
now wraps the parent, so I have renamed it to AlertTrait
below. I kept the name Parent
for continuity, although it is not really a parent now.
// Use it like this:
<AlertTrait renderComponent={Parent}/>
class AlertTrait extends Component {
// You will need to bind this function, if it uses 'this'
doAlert() {
alert('clicked');
}
render() {
return this.props.renderComponent({ doAlert: this.doAlert });
}
}
class Parent extends Component {
render() {
return (
<button onClick={this.props.doAlert}>Click</button>
);
}
}
In this case, the AlertTrait provides one or more traits which it passes down as props to whatever component it was given in its renderComponent
prop.
The Parent receives doAlert
as a prop, and can call it when needed.
(For clarity, I called the prop renderComponent
in the above example. But in the React docs linked above, they just call it render
.)
The Trait component can render stuff surrounding the Parent, in its render function, but it does not render anything inside the parent. Actually it could render things inside the Parent, if it passed another prop (e.g. renderChild
) to the parent, which the parent could then use during its render method.
This is somewhat different from what the OP asked for, but some people might end up here (like we did) because they wanted to create a reusable trait, and thought that a child component was a good way to do that.
I'm using this function
function isNull() {
for (var i = 0; i < arguments.length; i++) {
if (
typeof arguments[i] !== 'undefined'
&& arguments[i] !== undefined
&& arguments[i] != null
&& arguments[i] != NaN
&& arguments[i]
) return arguments[i];
}
}
test
console.log(isNull(null, null, undefined, 'Target'));

This raises the following import warning in python 3.6 and 3.7:
ImportWarning: can't resolve package from __spec__ or __package__, falling back on __name__ and __path__
If you with to ignore this warning (and maybe other ImportWarning

All these answers leaning towards LINQ are mainly talking about EASE of DEVELOPMENT which is more or less connected to poor quality of coding or laziness in coding. I am like that only.
Some advantages or Linq, I read here as , easy to test, easy to debug etc, but these are no where connected to Final output or end user. This is always going cause the trouble the end user on performance. Whats the point loading many things in memory and then applying filters on in using LINQ?
Again TypeSafety, is caution that "we are careful to avoid wrong typecasting" which again poor quality we are trying to improve by using linq. Even in that case, if anything in database changes, e.g. size of String column, then linq needs to be re-compiled and would not be typesafe without that .. I tried.
Although, we found is good, sweet, interesting etc while working with LINQ, it has shear disadvantage of making developer lazy :) and it is proved 1000 times that it is bad (may be worst) on performance compared to Stored Procs.
Stop being lazy. I am trying hard. :)
Answer corresponding to this by @Brad Parks Not sure about the MySQL version, but mine was 5.6, hence a little bit tweaking works:
I created a function debug_msg
which is function (not procedure) and returns text(no character limit) and then call the function as SELECT debug_msg
(params) AS my_res_set
, code as below:
CREATE DEFINER=`root`@`localhost` FUNCTION `debug_msg`(`enabled` INT(11), `msg` TEXT) RETURNS text CHARSET latin1
READS SQL DATA
BEGIN
IF enabled=1 THEN
return concat('** DEBUG:', "** ", msg);
END IF;
END
DELIMITER $$
CREATE DEFINER=`root`@`localhost` PROCEDURE `proc_func_call`(
IN RegionID VARCHAR(20),
IN RepCurrency INT(11),
IN MGID INT(11),
IN VNC VARCHAR(255)
)
BEGIN
SET @enabled = TRUE;
SET @mainQuery = "SELECT * FROM Users u";
SELECT `debug_msg`(@enabled, @mainQuery) AS `debug_msg1`;
SET @lastQuery = CONCAT(@mainQuery, " WHERE u.age>30);
SELECT `debug_msg`(@enabled, @lastQuery) AS `debug_msg2`;
END $$
DELIMITER
Where $GIT_DIR is the path to the folder to be searched (the git repo path), execute the following in terminal.
find $GIT_DIR -name *.git* -ok rm -Rf {} \;
This will recursively search for any directories or files containing ".git" in the file/directory name within the specified Git directory. This will include .git/ and .gitignore files and any other .git-like assets. The command is interactive and will ask before removing. To proceed with the deletion, simply enter y, then Enter.
If you don't have a common way to atomically update or insert (e.g., via a transaction) then you can fallback to another locking scheme. A 0-byte file, system mutex, named pipe, etc...

Since you want to pivot multiple columns of data, I would first suggest unpivoting the result
, score
and grade
columns so you don't have multiple columns but you will have multiple rows.
Depending on your version of SQL Server you can use the UNPIVOT function or CROSS APPLY. The syntax to unpivot the data will be similar to:
select ratio, col, value
from GRAND_TOTALS
cross apply
(
select 'result', cast(result as varchar(10)) union all
select 'score', cast(score as varchar(10)) union all
select 'grade', grade
) c(col, value)
See SQL Fiddle with Demo. Once the data has been unpivoted, then you can apply the PIVOT function:
select ratio = col,
[current ratio], [gearing ratio], [performance ratio], total
from
(
select ratio, col, value
from GRAND_TOTALS
cross apply
(
select 'result', cast(result as varchar(10)) union all
select 'score', cast(score as varchar(10)) union all
select 'grade', grade
) c(col, value)
) d
pivot
(
max(value)
for ratio in ([current ratio], [gearing ratio], [performance ratio], total)
) piv;
See SQL Fiddle with Demo. This will give you the result:
| RATIO | CURRENT RATIO | GEARING RATIO | PERFORMANCE RATIO | TOTAL |
|--------|---------------|---------------|-------------------|-----------|
| grade | Good | Good | Satisfactory | Good |
| result | 1.29400 | 0.33840 | 0.04270 | (null) |
| score | 60.00000 | 70.00000 | 50.00000 | 180.00000 |
Additionally you will want to use the Environment Variables for your paths if at all possible: http://en.wikipedia.org/wiki/Environment_variable#Default_Values_on_Microsoft_Windows

You don't need to wrap the iframe with an additional tag. Just make sure you increase the width and height of the iframe by the same amount you scale down the iframe.
e.g. to scale the iframe content to 80% :
#frame { /* Example size! */
height: 400px; /* original height */
width: 100%; /* original width */
}
#frame {
height: 500px; /* new height (400 * (1/0.8) ) */
width: 125%; /* new width (100 * (1/0.8) )*/
transform: scale(0.8);
transform-origin: 0 0;
}
Basically, to get the same size iframe you need to scale the dimensions.
None of these answers worked for me (tested in Safari 6.0) when trying to validate a date such as 2/31/2012, however, they work fine when trying any date greater than 31.
So I had to brute force a little. Assuming the date is in the format mm/dd/yyyy
. I am using @broox answer:
Date.prototype.valid = function() {
return isFinite(this);
}
function validStringDate(value){
var d = new Date(value);
return d.valid() && value.split('/')[0] == (d.getMonth()+1);
}
validStringDate("2/29/2012"); // true (leap year)
validStringDate("2/29/2013"); // false
validStringDate("2/30/2012"); // false
Just works:
const minute = Math.floor(( milliseconds % (1000 * 60 * 60)) / (1000 * 60));
const second = Math.floor((ms % (1000 * 60)) / 1000);

{
char *str = NULL;
char *old_json = NULL, *new_json = NULL;
va_list arg_ptr;
va_start(arg_ptr, format);
vasprintf(&str, format, arg_ptr);
// save old json
asprintf(&old_json, "%s", (*json == NULL ? "" : *json));
// calloc new json memory
new_json = (char *)calloc(strlen(old_json) + strlen(str) + 1, sizeof(char));
strcat(new_json, old_json);
strcat(new_json, str);
if (*json) free(*json);
*json = new_json;
free(old_json);
free(str);
return 0;
}
int main(int argc, char *argv[])
{
char *json = NULL;
str_append(&json, "name: %d, %d, %d", 1, 2, 3);
str_append(&json, "sex: %s", "male");
str_append(&json, "end");
str_append(&json, "");
str_append(&json, "{\"ret\":true}");
int i;
for (i = 0; i < 10; i++) {
str_append(&json, "id-%d", i);
}
printf("%s\n", json);
if (json) free(json);
return 0;
}
OFFICE 2013 INSTRUCTIONS:
(For Windows 7 (x64) | MS Office 32-Bit)
Option 1 | Check if ability already exists | 2 minutes
Option 2 | The "Monthview" Control doesn't currently exist | 5 minutes
Okay, either of these two steps should work for you if you have Office 2013 (32-Bit) on Windows 7 (x64). Some of the steps may be different if you have a different combo of Windows 7 & Office 2013.
The "Monthview" control will be your fully fleshed out 'DatePicker'. It comes equipped with its own properties and image. It works very well. Good luck.

But keep in mind, this doesn't work on some devices.
As for the workaround (without using non-portable -P
), you can temporary replace a new-line character with the different one and change it back, e.g.:
grep -o "_foo_" <(paste -sd_ file) | tr -d '_'
Basically it's looking for exact match _foo_
where _
means \n
(so __
= \n\n
). You don't have to translate it back by tr '_' '\n'
, as each pattern would be printed in the new line anyway, so removing _
is enough.
Again for completeness I'll add my most useful use-case for with
statements.
I do a lot of scientific computing and for some activities I need the Decimal
library for arbitrary precision calculations. Some part of my code I need high precision and for most other parts I need less precision.
I set my default precision to a low number and then use with
to get a more precise answer for some sections:
from decimal import localcontext
with localcontext() as ctx:
ctx.prec = 42 # Perform a high precision calculation
s = calculate_something()
s = +s # Round the final result back to the default precision
I use this a lot with the Hypergeometric Test which requires the division of large numbers resulting form factorials. When you do genomic scale calculations you have to be careful of round-off and overflow errors.

If you are creating new array then try this :
$arr = ['key' => 'value'];
And if array is already created then try this :
$arr['key'] = 'value';
If there's always a single CRLF, then:
myString = myString.Substring(0, myString.Length - 2);
If it may or may not have it, then:
Regex re = new Regex("\r\n$");
re.Replace(myString, "");
Both of these (by design), will remove at most a single CRLF. Cache the regex for performance.

(global-set-key (kbd "C-z") 'undo)
Just download the file, put it in your lisp-path and paste the above in your .emacs

I found an app for Mac OSX called ICOBundle that allows you to easily drop a selection of ico files in different sizes onto the ICOBundle.app, prompts you for a folder destination and file name, and it creates the multi-icon .ico file.
Now if it were only possible to mix-in an animated gif version into that one file it'd be a complete icon set, sadly not possible and requires a separate file and code snippet.
You are getting the error because range() only takes int values as parameters.
Try using int() to convert your inputs.

In ASP.Net you can use System.Web.HttpUtility
to safely encode the cookie value before writing to the cookie and convert it back to its original form on reading it out.
// Encode
HttpUtility.UrlEncode(cookieData);
// Decode
HttpUtility.UrlDecode(encodedCookieData);
This will stop ampersands and equals signs spliting a value into a bunch of name/value pairs as it is written to a cookie.
You should create custom helper for just changing string format except using controller call.
Ok here is my version of doing this. I noticed that you want your output to be 7
, which means you dont want to count special characters and numbers. So here is regex pattern:
re.findall("[a-zA-Z_]+", string)
Where [a-zA-Z_]
means it will match any character beetwen a-z
(lowercase) and A-Z
(upper case).
About spaces. If you want to remove all extra spaces, just do:
string = string.rstrip().lstrip() # Remove all extra spaces at the start and at the end of the string
while " " in string: # While there are 2 spaces beetwen words in our string...
string = string.replace(" ", " ") # ... replace them by one space!
If you are interested to detect simple IR light blob through haar cascade, it will be very odd to do. Because simple IR blob does not have enough features to be trained through opencv like other objects (face, eyes,nose etc). Because IR is just a simple light having only one feature of brightness in my point of view. But if you want to learn how to train a classifier following link will help you alot.
http://note.sonots.com/SciSoftware/haartraining.html
And if you just want to detect IR blob, then you have two more possibilities, one is you go for DIP algorithms to detect bright region and the other one which I recommend you is you can use an IR cam which just pass the IR blob and you can detect easily the IR blob by using opencv blob functiuons. If you think an IR cam is expansive, you can make simple webcam to an IR cam by removing IR blocker (if any) and add visible light blocker i.e negative film, floppy material or any other. You can check the following link to convert simple webcam to IR cam.

Use a regex: .
Match m = Regex.Match(text, @"(.+? .+?) ");
if (m.Success) {
do_something_with(m.Groups[1].Value);
}

<textarea cols="30" rows="4" name="update" id="update" maxlength="200" ></textarea>
<br />
<input name="submit_button" type="submit" value=" Update " id="update_button" class="update_button"/> <!-- notice added name="" -->
</form>
on your full page, you could have this
<?php
// check if the form was submitted
if ($_POST['submit_button']) {
// this means the submit button was clicked, and the form has refreshed the page
// to access the content in text area, you would do this
$a = $_POST['update'];
// now $a contains the data from the textarea, so you can do whatever with it
// this will echo the data on the page
echo $a;
}
else {
// form not submitted, so show the form
?>
<form method="post" action="<?php echo $_SERVER['PHP_SELF']; ?>"> <!-- notice the updated action -->

Besides all cited above, there are jQuery plugins that may help too:
for individual checkboxes:
for tree-like behavior checkboxes:
EDIT Both libraries uses the 'indeterminate' checkbox attribute, since this attribute in Html5 is just for styling (https://www.w3.org/TR/2011/WD-html5-20110113/number-state.html#checkbox-state), the null value is never sent to the server (checkboxes can only have two values).
To be able to submit this value to the server, I've create hidden counterpart fields which are populated on form submission using some javascript. On the server side, you'd need to check those counterpart fields instead of original checkboxes, of course.
I've used the first library (standalone checkboxes) where it's important to:
Hope that helps.
Try like this:
var clr = 'green';
var html = '<font color="' + clr + '">' + onlineff + ' </font>';
This being said, you should avoid using the <font>
tag. It is now deprecated. Use CSS to change the style (color) of a given element in your markup.
If you're stuck with pre-5.10, then the solutions provided above will not fully replicate the say
function. For example
sub say { print @_, "\n"; }
Will not work with invocations such as
say for @arr;
or
for (@arr) {
say;
}
... because the above function does not act on the implicit global $_
like print
and the real say
function.
To more closely replicate the perl 5.10+ say
you want this function
sub say {
if (@_) { print @_, "\n"; }
else { print $_, "\n"; }
}
Which now acts like this
my @arr = qw( alpha beta gamma );
say @arr;
# OUTPUT
# alphabetagamma
#
say for @arr;
# OUTPUT
# alpha
# beta
# gamma
#
The say
builtin in perl6 behaves a little differently. Invoking it with say @arr
or @arr.say
will not just concatenate the array items, but instead prints them separated with the list separator. To replicate this in perl5 you would do this
sub say {
if (@_) { print join($", @_) . "\n"; }
else { print $_ . "\n"; }
}
$"
is the global list separator variable, or if you're using English.pm
then is is $LIST_SEPARATOR
It will now act more like perl6, like so
say @arr;
# OUTPUT
# alpha beta gamma
#
Remove the function and check the output of:
var_dump(function_exists('parseDate'));
In which case, change the name of the function.
If you get false, you're including the file with that function twice, replace :
include
by
include_once
And replace :
require
by
require_once

Most likely your query failed, and the query call returned a boolean FALSE (or an error object of some sort), which you then try to use as if was a resultset object, causing the error. Try something like var_dump($result)
to see what you really got.
Check for errors after EVERY database query call. Even if the query itself is syntactically valid, there's far too many reasons for it to fail anyways - checking for errors every time will save you a lot of grief at some point.
try this
$ cmd='mysql AMORE -u root --password="password" -h localhost -e "select host from amoreconfig"'
$ eval $cmd
Please check: http://man7.org/linux/man-pages/man5/proc.5.html
address perms offset dev inode pathname
00400000-00452000 r-xp 00000000 08:02 173521 /usr/bin/dbus-daemon
The address field is the address space in the process that the mapping occupies.
The perms field is a set of permissions:
r = read
w = write
x = execute
s = shared
p = private (copy on write)
The offset field is the offset into the file/whatever;
dev is the device (major:minor);
inode is the inode on that device.0 indicates that no inode is associated with the memoryregion, as would be the case with BSS (uninitialized data).
The pathname field will usually be the file that is backing the mapping. For ELF files, you can easily coordinate with the offset field by looking at the Offset field in the ELF program headers (readelf -l).
Under Linux 2.0, there is no field giving pathname.
The following code works more or less as one would expect a type-switch that only looks at the actual type (e.g. what is returned by GetType()
).
public static void TestTypeSwitch()
{
var ts = new TypeSwitch()
.Case((int x) => Console.WriteLine("int"))
.Case((bool x) => Console.WriteLine("bool"))
.Case((string x) => Console.WriteLine("string"));
ts.Switch(42);
ts.Switch(false);
ts.Switch("hello");
}
Here is the machinery required to make it work.
public class TypeSwitch
{
Dictionary<Type, Action<object>> matches = new Dictionary<Type, Action<object>>();
public TypeSwitch Case<T>(Action<T> action) { matches.Add(typeof(T), (x) => action((T)x)); return this; }
public void Switch(object x) { matches[x.GetType()](x); }
}
You need the :not()
selector:
$('div[class^="first-"]:not(.first-bar)')
or, alternatively, the .not()
method:
$('div[class^="first-"]').not('.first-bar');
Not sure what kind of text box you are refering to. However, I'm not sure if you can do this in a text box on a user form.
A text box on a sheet you can though.
Sheets("Sheet1").Shapes("TextBox 1").TextFrame2.TextRange.Text = "R2=" & variable
Sheets("Sheet1").Shapes("TextBox 1").TextFrame2.TextRange.Characters(2, 1).Font.Superscript = msoTrue
And same thing for an excel cell
Sheets("Sheet1").Range("A1").Characters(2, 1).Font.Superscript = True
If this isn't what you're after you will need to provide more information in your question.
EDIT: posted this after the comment sorry
This answer is based on Yann's answer. It will set the aspect ratio for linear or log-log plots. I've used additional information from https://stackoverflow.com/a/16290035/2966723 to test if the axes are log-scale.
def forceAspect(ax,aspect=1):
#aspect is width/height
scale_str = ax.get_yaxis().get_scale()
xmin,xmax = ax.get_xlim()
ymin,ymax = ax.get_ylim()
if scale_str=='linear':
asp = abs((xmax-xmin)/(ymax-ymin))/aspect
elif scale_str=='log':
asp = abs((scipy.log(xmax)-scipy.log(xmin))/(scipy.log(ymax)-scipy.log(ymin)))/aspect
ax.set_aspect(asp)
Obviously you can use any version of log
you want, I've used scipy
, but numpy
or math
should be fine.
Employee Table
Name, DoB, Salary
Tomas , 2/10/1982, 300
Daniel , 3/11/1990, 400
Kwame , 2/10/1998, 520
The Comparable interface allows you to sort a list of objects eg Employees with reference to one primary field – for instance, you could sort by name or by salary with the CompareTo() method
emp1.getName().compareTo(emp2.getName())
A more flexible interface for such requirements is provided by the Comparator interface, whose only method is compare()
public interface Comparator<Employee> {
int compare(Employee obj1, Employee obj2);
}
Sample code
public class NameComparator implements Comparator<Employee> {
public int compare(Employee e1, Employee e2) {
// some conditions here
return e1.getName().compareTo(e2.getName()); // returns 1 since (T)omas > (D)an
return e1.getSalary().compareTo(e2.getSalary()); // returns -1 since 400 > 300
}
}
just create a new sheet with cells with linebreak, save it to csv then open it with an editor that can show the end of line characters (like notepad++). By doing that you will notice that a linebreak in a cell is coded with LF while a "real" end of line is code with CR LF. Voilà, now you know how to generate a "correct" csv file for excel.
This exception also happens if don't use transactions properly. In my case, I put transaction.Commit()
right after command.ExecuteReaderAsync()
, and did not wait to commit the transaction until reader.ReadAsync()
were called. The proper order:
We can't talk about virtual members without referring to polymorphism. In fact, a function, property, indexer or event in a base class marked as virtual will allow override from a derived class.
By default, members of a class are non-virtual and cannot be marked as that if static, abstract, private, or override modifiers.
Example Let's consider the ToString() method in System.Object. Because this method is a member of System.Object it's inherited in all classes and will provide the ToString() methods to all of them.
namespace VirtualMembersArticle
{
public class Company
{
public string Name { get; set; }
}
class Program
{
static void Main(string[] args)
{
Company company = new Company() { Name = "Microsoft" };
Console.WriteLine($"{company.ToString()}");
Console.ReadLine();
}
}
}
The output of the previous code is:
VirtualMembersArticle.Company
Let's consider that we want to change the standard behavior of the ToString() methods inherited from System.Object in our Company class. To achieve this goal it's enough to use the override keyword to declare another implementation of that method.
public class Company
{
...
public override string ToString()
{
return $"Name: {this.Name}";
}
}
Now, when a virtual method is invoked, the run-time will check for an overriding member in its derived class and will call it if present. The output of our application will then be:
Name: Microsoft
In fact, if you check the System.Object class you will find that the method is marked as virtual.
namespace System
{
[NullableContextAttribute(2)]
public class Object
{
....
public virtual string? ToString();
....
}
}
The code date.to_time.to_i
should work fine. The Rails console session below shows an example:
>> Date.new(2009,11,26).to_time
=> Thu Nov 26 00:00:00 -0800 2009
>> Date.new(2009,11,26).to_time.to_i
=> 1259222400
>> Time.at(1259222400)
=> Thu Nov 26 00:00:00 -0800 2009
Note that the intermediate DateTime object is in local time, so the timestamp might be a several hours off from what you expect. If you want to work in UTC time, you can use the DateTime's method "to_utc".
C:\tmp\text>dos2unix hello.txt helloUNIX.txt
Sed is even more widely available and can do this kind of thing also if dos2unix is not installed
C:\tmp\text>sed s/\r// hello.txt > helloUNIX.txt
You could also try tr:
cat hello.txt | tr -d \r > helloUNIX2.txt
Here are the results:

Based on what it looks like you're trying to do you could use this approach.
In your case, your functions would all live in the module foo. Then you could:
import foo
func_name = parse_commandline()
method_to_call = getattr(foo, func_name)
result = method_to_call()
Or more succinctly:
import foo
result = getattr(foo, parse_commandline())()
I thought I'd add that for Tomcat 7.x, <Context>
is not in the server.xml
, but in the context.xml
. Removing and re-adding the project did not seem to help my similar issue, which was a web.xml issue, which I found out by checking the context.xml
which had this line in the <Context>
section:
<WatchedResource>WEB-INF/web.xml</WatchedResource>
The solution in WARNING: Setting property 'source' to 'org.eclipse.jst.jee.server:appname' did not find a matching property brought me closer to my answer, as the change of publishing into a separate XML did resolve the error reported above for me, but unfortunately it generated a second error that I'm still investigating.
WARNING: [SetContextPropertiesRule]{Context} Setting property 'source' to 'org.eclipse.jst.jee.server:myproject' did not find a matching property.
I know this is an old thread, but I feel the need to post the proper answer. The actual answer to this question is that you need to create a new stacking context on the parent of the element with the pseudo element (and you actually have to give it a z-index, not just a position).
Like this:
#parent {
position: relative;
z-index: 1;
}
#pseudo-parent {
position: absolute;
/* no z-index allowed */
}
#pseudo-parent:after {
position: absolute;
top:0;
z-index: -1;
}
It has nothing to do with using :before or :after pseudo elements.
#parent { position: relative; z-index: 1; }_x000D_
#pseudo-parent { position: absolute; } /* no z-index required */_x000D_
#pseudo-parent:after { position: absolute; z-index: -1; }_x000D_
_x000D_
/* Example styling to illustrate */_x000D_
#pseudo-parent { background: #d1d1d1; }_x000D_
#pseudo-parent:after { margin-left: -3px; content: "M" }
_x000D_
<div id="parent">_x000D_
<div id="pseudo-parent">_x000D_
_x000D_
</div>_x000D_
</div>
_x000D_

An "unexpected T_VARIABLE
" means that there's a literal $variable
name, which doesn't fit into the current expression/statement structure.
It most commonly indicates a missing semicolon in the previous line. Variable assignments following a statement are a good indicator where to look:
?
func1()
$var = 1 + 2; # parse error in line +2
A frequent mishap are string concatenations with forgotten .
operator:
?
print "Here comes the value: " $value;
Btw, you should prefer string interpolation (basic variables in double quotes) whenever that helps readability. Which avoids these syntax issues.
String interpolation is a scripting language core feature. No shame in utilizing it. Ignore any micro-optimization advise about variable
.
concatenation being faster. It's not.
Of course the same issue can arise in other expressions, for instance arithmetic operations:
?
print 4 + 7 $var;
PHP can't guess here if the variable should have been added, subtracted or compared etc.
Same for syntax lists, like in array populations, where the parser also indicates an expected comma ,
for example:
?
$var = array("1" => $val, $val2, $val3 $val4);
Or functions parameter lists:
?
function myfunc($param1, $param2 $param3, $param4)
Equivalently do you see this with list
or global
statements, or when lacking a ;
semicolon in a for
loop.
This parser error also occurs in class declarations. You can only assign static constants, not expressions. Thus the parser complains about variables as assigned data:
class xyz { ?
var $value = $_GET["input"];
Unmatched }
closing curly braces can in particular lead here. If a method is terminated too early (use proper indentation!), then a stray variable is commonly misplaced into the class declaration body.
You can also never have a variable follow an identifier directly:
?
$this->myFunc$VAR();
Btw, this is a common example where the intention was to use variable variables perhaps. In this case a variable property lookup with $this->{"myFunc$VAR"}();
for example.
Take in mind that using variable variables should be the exception. Newcomers often try to use them too casually, even when arrays would be simpler and more appropriate.
Hasty typing may lead to forgotten opening or closing parenthesis
for if
and for
and foreach
statements:
?
foreach $array as $key) {
Solution: add the missing opening (
between statement and variable.
?
if ($var = pdo_query($sql) {
$result = …
The curly {
brace does not open the code block, without closing the if
expression with the )
closing parenthesis first.
?
else ($var >= 0)
Solution: Remove the conditions from else
or use elseif
.
?
function() use $var {}
Solution: Add brackets around $var
.
As mentioned in the reference answer on "Invisible stray Unicode" (such as a non-breaking space), you might also see this error for unsuspecting code like:
<?php
?
$var = new PDO(...);
It's rather prevalent in the start of files and for copy-and-pasted code. Check with a hexeditor, if your code does not visually appear to contain a syntax issue.
Another solution, it covered the problem I had with clicking descendants of the popover:
$(document).mouseup(function (e) {
// The target is not popover or popover descendants
if (!$(".popover").is(e.target) && 0 === $(".popover").has(e.target).length) {
$("[data-toggle=popover]").popover('hide');
}
});
ev
icon next to elements
Within the Firefox Developer Tools' Inspector panel lists all events bound to an element.
First select an element with Ctrl + Shift + C, e.g. Stack Overflow's upvote arrow.
Click on the ev
icon to the right of the element, and a dialogue opens:
Click on the pause sign ||
symbol for the event you want, and this opens the debugger on the line of the handler.
You can now place a breakpoint there as usual in the debugger, by clicking on the left margin of the line.
This is mentioned at: https://developer.mozilla.org/en-US/docs/Tools/Page_Inspector/How_to/Examine_event_listeners
Unfortunately, I couldn't find a way for this to play nicely with prettyfication, it just seems to open at the minified line: How to beautify Javascript and CSS in Firefox / Firebug?
Tested on Firefox 42.
This happens because in r6 it shows an error when you try to extend private styles.

Relative imports use a module's name attribute to determine that module's position in the package hierarchy. If the module's name does not contain any package information (e.g. it is set to 'main') then relative imports are resolved as if the module were a top level module, regardless of where the module is actually located on the file system.
Wrote a little python package to PyPi that might help viewers of this question. The package acts as workaround if one wishes to be able to run python files containing imports containing upper level packages from within a package / project without being directly in the importing file's directory. https://pypi.org/project/import-anywhere/
For those from 2018 and beyond, using npm version 5 or later: edit your package-lock.json
: remove the library from "requires"
section and add it under "dependencies".
For example, you want deglob
package to use glob
package version 3.2.11
instead of its current one. You open package-lock.json
and see:
"deglob": {
"version": "2.1.0",
"resolved": "https://registry.npmjs.org/deglob/-/deglob-2.1.0.tgz",
"integrity": "sha1-TUSr4W7zLHebSXK9FBqAMlApoUo=",
"requires": {
"find-root": "1.1.0",
"glob": "7.1.2",
"ignore": "3.3.5",
"pkg-config": "1.1.1",
"run-parallel": "1.1.6",
"uniq": "1.0.1"
}
},
Remove "glob": "7.1.2",
from "requires"
, add "dependencies"
with proper version:
"deglob": {
"version": "2.1.0",
"resolved": "https://registry.npmjs.org/deglob/-/deglob-2.1.0.tgz",
"integrity": "sha1-TUSr4W7zLHebSXK9FBqAMlApoUo=",
"requires": {
"find-root": "1.1.0",
"ignore": "3.3.5",
"pkg-config": "1.1.1",
"run-parallel": "1.1.6",
"uniq": "1.0.1"
},
"dependencies": {
"glob": {
"version": "3.2.11"
}
}
},
Now remove your node_modules
folder, run npm install
and it will add missing parts to the "dependencies"
section.
First of all, Applets are designed to be run from within the context of a browser (or applet viewer), they're not really designed to be added into other containers.
Technically, you can add a applet to a frame like any other component, but personally, I wouldn't. The applet is expecting a lot more information to be available to it in order to allow it to work fully.
Instead, I would move all of the "application" content to a separate component, like a JPanel
for example and simply move this between the applet or frame as required...
ps- You can use f.setLocationRelativeTo(null)
to center the window on the screen ;)
Updated
You need to go back to basics. Unless you absolutely must have one, avoid applets until you understand the basics of Swing, case in point...
Within the constructor of GalzyTable2
you are doing...
JApplet app = new JApplet(); add(app); app.init(); app.start();
...Why are you adding another applet to an applet??
Case in point...
Within the main
method, you are trying to add the instance of JFrame
to itself...
f.getContentPane().add(f, button2);
Instead, create yourself a class that extends from something like JPanel
, add your UI logical to this, using compound components if required.
Then, add this panel to whatever top level container you need.

Take the time to read through Creating a GUI with Swing and Laying components out in a container
"2014-01-01T23:28:56.782Z"
The date is represented in a standard and sortable format that represents a UTC time (indicated by the Z). ISO 8601 also supports time zones by replacing the Z with + or – value for the timezone offset:
"2014-02-01T09:28:56.321-10:00"
There are other variations of the timezone encoding in the ISO 8601 spec, but the –10:00 format is the only TZ format that current JSON parsers support. In general it’s best to use the UTC based format (Z) unless you have a specific need for figuring out the time zone in which the date was produced (possible only in server side generation).
NB:
var date = new Date();
console.log(date); // Wed Jan 01 2014 13:28:56 GMT-
1000 (Hawaiian Standard Time)
var json = JSON.stringify(date);
console.log(json); // "2014-01-01T23:28:56.782Z"
To tell you that's the preferred way even though JavaScript doesn't have a standard format for it
// JSON encoded date
var json = "\"2014-01-01T23:28:56.782Z\"";
var dateStr = JSON.parse(json);
console.log(dateStr); // 2014-01-01T23:28:56.782Z
We can use following code
textBox1.DataBindings.Add("Text", model, "Name", false, DataSourceUpdateMode.OnPropertyChanged);
Where
"Text"
– the property of textbox model
– the model object enter code here "Name"
– the value of model which to bind the textbox.You can add one li
element where you want to add divider
<ul>
<li> your content </li>
<li class="divider-vertical-second-menu"></li>
<li> NExt content </li>
<li class="divider-vertical-second-menu"></li>
<li> last item </li>
</ul>
In CSS you can Add following code.
.divider-vertical-second-menu{
height: 40px;
width: 1px;
margin: 0 5px;
overflow: hidden;
background-color: #DDD;
border-right: 2px solid #FFF;
}
This will increase you speed of execution as it will not load any image. just test it out.. :)
Another option:
def map = ['a':1, 'b':2, 'c':3]
map.each{
println it.key +" "+ it.value
}
Using Spring's SimpleJdbcTemplate, I got it when I tried to do this:
String sqlString = "select pwy_code from approver where university_id = '123'";
List<Map<String, Object>> rows = getSimpleJdbcTemplate().queryForList(sqlString, uniId);
I had an argument to queryForList that didn't correspond to a question mark in the SQL. The first line should have been:
String sqlString = "select pwy_code from approver where university_id = ?";
I think I've found it....from http://www-cs-students.stanford.edu/~blynn/gitmagic/ch02.html
Sometimes you just want to go back and forget about every change past a certain point because they're all wrong.
Start with:
$ git log
which shows you a list of recent commits, and their SHA1 hashes.
Next, type:
$ git reset --hard SHA1_HASH
to restore the state to a given commit and erase all newer commits from the record permanently.
Try this CSS:
body {
margin: 0;
padding: 0;
}
.logo {
float: left;
}
/* ~~ Top Navigation Bar ~~ */
#navigation-container {
width: 1200px;
margin: 0 auto;
height: 70px;
}
.navigation-bar {
background-color: #352d2f;
height: 70px;
width: 100%;
}
#navigation-container img {
float: left;
}
#navigation-container ul {
padding: 0px;
margin: 0px;
text-align: center;
display:inline-block;
}
#navigation-container li {
list-style-type: none;
padding: 0px;
height: 24px;
margin-top: 4px;
margin-bottom: 4px;
display: inline;
}
#navigation-container li a {
color: white;
font-size: 16px;
font-family: "Trebuchet MS", Arial, Helvetica, sans-serif;
text-decoration: none;
line-height: 70px;
padding: 5px 15px;
opacity: 0.7;
}
#menu {
float: right;
}
You should be able to build a string holding the binary data using something like:
data = "fef0babe"
bits = ""
for x in xrange(0, len(data), 2)
bits += chr(int(data[x:x+2], 16))
This is probably not the fastest way (many string appends), but quite simple using only core Python.
This is normal problem. In wich order and export function sometimes get turned off.
right click on project<properties< there u hav option build path < and there ORDER AND EXPORT< click right all the options....all the things are right back.
Look at this tutorial or this one, they are both pretty simple. If you are interested in an alternative this is how you do file I/O in C.
Some things to keep in mind, use single quotes '
when dealing with single characters, and double "
for strings. Also it is a bad habit to use global variables when not necessary.
Have fun!
How do I properly compare strings?
char input[40];
char check[40];
strcpy(input, "Hello"); // input assigned somehow
strcpy(check, "Hello"); // check assigned somehow
// insufficient
while (check != input)
// good
while (strcmp(check, input) != 0)
// or
while (strcmp(check, input))
Let us dig deeper to see why check != input
is not sufficient.
In C, string is a standard library specification.
A string is a contiguous sequence of characters terminated by and including the first null character.
C11 §7.1.1 1
input
above is not a string. input
is array 40 of char.
The contents of input
can become a string.
In most cases, when an array is used in an expression, it is converted to the address of its 1st element.
The below converts check
and input
to their respective addresses of the first element, then those addresses are compared.
check != input // Compare addresses, not the contents of what addresses reference
To compare strings, we need to use those addresses and then look at the data they point to.
strcmp()
does the job. §7.23.4.2
int strcmp(const char *s1, const char *s2);
The
strcmp
function compares the string pointed to bys1
to the string pointed to bys2
.The
strcmp
function returns an integer greater than, equal to, or less than zero, accordingly as the string pointed to bys1
is greater than, equal to, or less than the string pointed to bys2
.
Not only can code find if the strings are of the same data, but which one is greater/less when they differ.
The below is true when the string differ.
strcmp(check, input) != 0
For insight, see Creating my own strcmp()
function
I've just used Deferred in real code. In project jQuery Terminal I have function exec that call commands defined by user (like he was entering it and pressing enter), I've added Deferreds to the API and call exec with arrays. like this:
terminal.exec('command').then(function() {
terminal.echo('command finished');
});
or
terminal.exec(['command 1', 'command 2', 'command 3']).then(function() {
terminal.echo('all commands finished');
});
the commands can run async code, and exec need to call user code in order. My first api use pair of pause/resume calls and in new API I call those automatic when user return promise. So user code can just use
return $.get('/some/url');
or
var d = new $.Deferred();
setTimeout(function() {
d.resolve("Hello Deferred"); // resolve value will be echoed
}, 500);
return d.promise();
I use code like this:
exec: function(command, silent, deferred) {
var d;
if ($.isArray(command)) {
return $.when.apply($, $.map(command, function(command) {
return self.exec(command, silent);
}));
}
// both commands executed here (resume will call Term::exec)
if (paused) {
// delay command multiple time
d = deferred || new $.Deferred();
dalyed_commands.push([command, silent, d]);
return d.promise();
} else {
// commands may return promise from user code
// it will resolve exec promise when user promise
// is resolved
var ret = commands(command, silent, true, deferred);
if (!ret) {
if (deferred) {
deferred.resolve(self);
return deferred.promise();
} else {
d = new $.Deferred();
ret = d.promise();
ret.resolve();
}
}
return ret;
}
},
dalyed_commands is used in resume function that call exec again with all dalyed_commands.
and part of the commands function (I've stripped not related parts)
function commands(command, silent, exec, deferred) {
var position = lines.length-1;
// Call user interpreter function
var result = interpreter.interpreter(command, self);
// user code can return a promise
if (result != undefined) {
// new API - auto pause/resume when using promises
self.pause();
return $.when(result).then(function(result) {
// don't echo result if user echo something
if (result && position === lines.length-1) {
display_object(result);
}
// resolve promise from exec. This will fire
// code if used terminal::exec('command').then
if (deferred) {
deferred.resolve();
}
self.resume();
});
}
// this is old API
// if command call pause - wait until resume
if (paused) {
self.bind('resume.command', function() {
// exec with resume/pause in user code
if (deferred) {
deferred.resolve();
}
self.unbind('resume.command');
});
} else {
// this should not happen
if (deferred) {
deferred.resolve();
}
}
}
I was getting the same error in python 3.4.3 too and I tried using the solutions mentioned here and elsewhere with no success.
Microsoft makes a compiler available for Python 2.7 but it didn't do me much good since I am on 3.4.3.
Python since 3.3 has transitioned over to 2010 and you can download and install Visual C++ 2010 Express for free here: https://www.visualstudio.com/downloads/download-visual-studio-vs#d-2010-express
Here is the official blog post talking about the transition to 2010 for 3.3: http://blog.python.org/2012/05/recent-windows-changes-in-python-33.html
Because previous versions gave a different error for vcvarsall.bat I would double check the version you are using with "pip -V"
C:\Users\B>pip -V
pip 6.0.8 from C:\Python34\lib\site-packages (python 3.4)
As a side note, I too tried using the latest version of VC++ (2013) first but it required installing 2010 express.
From that point forward it should work for anyone using the 32 bit version, if you are on the 64 bit version you will then get the ValueError: ['path'] message because VC++ 2010 doesn't have a 64 bit compuler. For that you have to get the Microsoft SDK 7.1. I can't hyperlink the instruction for 64 bit because I am limited to 2 links per post but its at
Python PIP has issues with path for MS Visual Studio 2010 Express for 64-bit install on Windows 7
If you don't want to load the calendar twice and you don't have a version where defaultDate is implemented, do the following:
Change the following method:
function Calendar(element, options, eventSources) {
...
var date = new Date();
...
}
to:
function Calendar(element, options, eventSources) {
...
var date = options.defaultDate ? options.defaultDate : new Date();
...
}
In java, every numeric expression like:
anyPrimitive zas = 1;
anyPrimitive bar = 3;
?? x = zas + bar
x will always result to be at least an int, or a long if one of the addition elements was a long.
But there's are some quirks tough
byte a = 1; // 1 is an int, but it won't compile if you use a variable
a += 2; // the shortcut works even when 2 is an int
a++; // the post and pre increment operator work
use blank? http://api.rubyonrails.org/classes/Object.html#method-i-blank-3F
unless params[:one].blank? && params[:two].blank?
will return true if its empty or nil
also... that will not work if you are testing boolean values.. since
>> false.blank?
=> true
in that case you could use
unless params[:one].to_s.blank? && params[:two].to_s.blank?
html5rocks.com has a very good tutorial on this stuff, and this might be a little late, but I myself didn't know this existed. w3schools also has a way to do this using their new library called w3.js. The thing is, this requires the use of a web server and and HTTPRequest object. You can't actually load these locally and test them on your machine. What you can do though, is use polyfills provided on the html5rocks link at the top, or follow their tutorial. With a little JS magic, you can do something like this:
var link = document.createElement('link');
if('import' in link){
//Run import code
link.setAttribute('rel','import');
link.setAttribute('href',importPath);
document.getElementsByTagName('head')[0].appendChild(link);
//Create a phantom element to append the import document text to
link = document.querySelector('link[rel="import"]');
var docText = document.createElement('div');
docText.innerHTML = link.import;
element.appendChild(docText.cloneNode(true));
} else {
//Imports aren't supported, so call polyfill
importPolyfill(importPath);
}
This will make the link (Can change to be the wanted link element if already set), set the import (unless you already have it), and then append it. It will then from there take that and parse the file in HTML, and then append it to the desired element under a div. This can all be changed to fit your needs from the appending element to the link you are using. I hope this helped, it may irrelevant now if newer, faster ways have come out without using libraries and frameworks such as jQuery or W3.js.
UPDATE: This will throw an error saying that the local import has been blocked by CORS policy. Might need access to the deep web to be able to use this because of the properties of the deep web. (Meaning no practical use)
In addition to the other answers, you can use this less-known method to grab elements of a certain parent like so,
$('child', 'parent');
In your case, that would be
if ($(event.target, 'div#hello')[0]) console.log(`${event.target.tagName} is an offspring of div#hello`);
Note the use of commas between the child and parent and their separate quotation marks. If they were surrounded by the same quotes
$('child, parent');
you'd have an object containing both objects, regardless of whether they exist in their document trees.
Thanks - this is one of 2 links that com up if you google for php apache windows absolute path.
As a newbie to intermed PHP developer I didnt understand why absolute paths on apache windopws systems would be c:\xampp\htdocs (apache document root - XAMPP default) instead of /
thus if in http//localhost/myapp/subfolder1/subfolder2/myfile.php I wanted to include a file from http//localhost/myapp
I would need to specify it as: include("c:\xampp\htdocs\myapp\includeme.php") or include("../../includeme.php")
AND NOT include("/myapp/includeme.php")
If you are having trouble debugging the code in the Startup
class, I have also had this problem - or I thought I did. The code was firing but I believe it happens before the debugger has attached so you cannot set breakpoints on the code and see what is happening.
You can prove this by throwing an exception in the Configuration
method of the Startup
class.
use following method to convert bitmap to byte array:
ByteArrayOutputStream byteArrayOutputStream = new ByteArrayOutputStream();
bitmap.compress(Bitmap.CompressFormat.PNG, 100, byteArrayOutputStream);
byte[] byteArray = byteArrayOutputStream .toByteArray();
to encode base64 from byte array use following method
String encoded = Base64.encodeToString(byteArray, Base64.DEFAULT);
Okay, I figured this out.
You will need html2canvas and pdfmake. You do NOT need to do any injection in your app.js to either, just include in your script tags
On the div that you want to create the PDF of, add an ID name like below:
<div id="exportthis">
In your Angular controller use the id of the div in your call to html2canvas:
change the canvas to an image using toDataURL()
Then in your docDefinition for pdfmake assign the image to the content.
The completed code in your controller will look like this:
html2canvas(document.getElementById('exportthis'), {
onrendered: function (canvas) {
var data = canvas.toDataURL();
var docDefinition = {
content: [{
image: data,
width: 500,
}]
};
pdfMake.createPdf(docDefinition).download("Score_Details.pdf");
}
});
I hope this helps someone else. Happy coding!
You are trying to add an integer into an ArrayList
that takes an array of integers Integer[]
. It should be
ArrayList<Integer> list = new ArrayList<>();
or better
List<Integer> list = new ArrayList<>();
I use .hpp because I want the user to differentiate what headers are C++ headers, and what headers are C headers.
This can be important when your project is using both C and C++ modules: Like someone else explained before me, you should do it very carefully, and its starts by the "contract" you offer through the extension
(Or .hxx, or .hh, or whatever)
This header is for C++ only.
If you're in a C module, don't even try to include it. You won't like it, because no effort is done to make it C-friendly (too much would be lost, like function overloading, namespaces, etc. etc.).
This header can be included by both a C source, and a C++ source, directly or indirectly.
It can included directly, being protected by the __cplusplus
macro:
extern "C"
.For example:
#ifndef MY_HEADER_H
#define MY_HEADER_H
#ifdef __cplusplus
extern "C"
{
#endif
void myCFunction() ;
#ifdef __cplusplus
} // extern "C"
#endif
#endif // MY_HEADER_H
Or it could be included indirectly by the corresponding .hpp header enclosing it with the extern "C"
declaration.
For example:
#ifndef MY_HEADER_HPP
#define MY_HEADER_HPP
extern "C"
{
#include "my_header.h"
}
#endif // MY_HEADER_HPP
and:
#ifndef MY_HEADER_H
#define MY_HEADER_H
void myCFunction() ;
#endif // MY_HEADER_H

Try this, it’ll sort the list in-place in descending order (there’s no need to specify a key in this case):
Process
listB = [24, 13, -15, -36, 8, 22, 48, 25, 46, -9]
listC = sorted(listB, reverse=True) # listB remains untouched
print listC
output:
[48, 46, 25, 24, 22, 13, 8, -9, -15, -36]
here is the split function that u asked

I made an adaption of @tokland's answer combined with the knowledge from http://veithen.github.io/2014/11/16/sigterm-propagation.html when I noticed that trap
doesn't trigger if I'm running a foreground process (not backgrounded with &
):
#!/bin/bash
# killable-shell.sh: Kills itself and all children (the whole process group) when killed.
# Adapted from http://stackoverflow.com/a/2173421 and http://veithen.github.io/2014/11/16/sigterm-propagation.html
# Note: Does not work (and cannot work) when the shell itself is killed with SIGKILL, for then the trap is not triggered.
trap "trap - SIGTERM && echo 'Caught SIGTERM, sending SIGTERM to process group' && kill -- -$$" SIGINT SIGTERM EXIT
echo $@
"$@" &
PID=$!
wait $PID
trap - SIGINT SIGTERM EXIT
wait $PID
Example of it working:
$ bash killable-shell.sh sleep 100
sleep 100
^Z
[1] + 31568 suspended bash killable-shell.sh sleep 100
$ ps aux | grep "sleep"
niklas 31568 0.0 0.0 19640 1440 pts/18 T 01:30 0:00 bash killable-shell.sh sleep 100
niklas 31569 0.0 0.0 14404 616 pts/18 T 01:30 0:00 sleep 100
niklas 31605 0.0 0.0 18956 936 pts/18 S+ 01:30 0:00 grep --color=auto sleep
$ bg
[1] + 31568 continued bash killable-shell.sh sleep 100
$ kill 31568
Caught SIGTERM, sending SIGTERM to process group

$ ps aux | grep "sleep"
niklas 31717 0.0 0.0 18956 936 pts/18 S+ 01:31 0:00 grep --color=auto sleep
For bash, store your command like this:
command="ls | grep -c '^'"
Run your command like this:
echo $command | bash
char *charPtr = "test string";
cout << charPtr << endl;
string str = charPtr;
cout << str << endl;
Syntax:
SELECT <Expression>[Arithmetic_Operator]<expression>...
FROM [Table_Name]
WHERE [expression];
Apache Thrift is a cross-language RPC option developed at Facebook. Works over sockets, function signatures are defined in text files in a language-independent way.
I got it working with a call to something as simple as
function fb_login() {
FB.login( function() {}, { scope: 'email,public_profile' } );
}
I don't know if facebook will ever be able to block this circumvention, but for now I can use whatever HTML or image I want to call fb_login
and it works fine.
Reference: Facebook API Docs
To fully overload it you also need to implement the __setitem__
and __delitem__
methods.
edit
I almost forgot... if you want to completely emulate a list, you also need __getslice__, __setslice__ and __delslice__
.
There are all documented in http://docs.python.org/reference/datamodel.html
You can use the easier function preg_match instead, It's better and faster than all of the other ones.
$var = "<tag>Get this var</tag>";
preg_match("/<tag>(.*)<\/tag>/", $var , $new_var);
echo $new_var['1'];
Output: Get this var
GroupBy using in Hibernate

GRANT SELECT ON *.* TO 'user'@'localhost' IDENTIFIED BY 'password';

pandas.Series.astype
You can do something like this :
weather["Temp"] = weather.Temp.astype(float)
You can also use pd.to_numeric
that will convert the column from object to float
Example :
s = pd.Series(['apple', '1.0', '2', -3])
print(pd.to_numeric(s, errors='ignore'))
print("=========================")
print(pd.to_numeric(s, errors='coerce'))
Output:
0 apple
1 1.0
2 2
3 -3
=========================
dtype: object
0 NaN
1 1.0
2 2.0
3 -3.0
dtype: float64
In your case you can do something like this:
weather["Temp"] = pd.to_numeric(weather.Temp, errors='coerce')
convert_objects
Example is as follows
>> pd.Series([1,2,3,4,'.']).convert_objects(convert_numeric=True)
0 1
1 2
2 3
3 4
4 NaN
dtype: float64
You can use this as follows:
weather["Temp"] = weather.Temp.convert_objects(convert_numeric=True)
NaN
... so be careful while using it.Perhaps appending DateTime.Now.Ticks
instead, is a tiny bit faster since you won't be creating 3 strings and the ticks value will always be unique also.
Use @@ROWCOUNT:
SELECT * FROM service s WHERE s.service_id = ?;
IF @@ROWCOUNT > 0
-- do stuff here.....
According to SQL Server Books Online:
Returns the number of rows affected by the last statement. If the number of rows is more than 2 billion, use ROWCOUNT_BIG.
Assuming the name of the dataframe after reading the excel sheet is df
, take an empty list (e.g. dataList
), iterate through the dataframe row by row and append to your empty list like-
dataList = [] #empty list
for index, row in df.iterrows():
mylist = [row.cluster, row.load_date, row.budget, row.actual, row.fixed_price]
dataList.append(mylist)
Or,
dataList = [] #empty list
for row in df.itertuples():
mylist = [row.cluster, row.load_date, row.budget, row.actual, row.fixed_price]
dataList.append(mylist)
No, if you print the dataList
, you will get each rows as a list in the dataList
.
If you run "dir c:\
", the last line will give you the free disk space.
Edit:
Better solution: "fsutil volume diskfree c:
"
Use UUID function.
I don't know the source of your procedures in PHP that generates unique values. If it is library function they should guarantee that your value is really unique. Check in documentation. You should, hovewer, use this function all the time. If you, for example, use PHP function to generate unique value, and then you decide to use MySQL function, you can generate value that already exist. In this case putting UNIQUE INDEX on the column is also a good idea.
php_flag display_errors on
To turn the actual display of errors on.
To set the types of errors you are displaying, you will need to use:
php_value error_reporting <integer>
Combined with the integer values from this page: http://php.net/manual/en/errorfunc.constants.php
Note if you use -1 for your integer, it will show all errors, and be future proof when they add in new types of errors.
Use CSS:
<input type="text" class="bigText" name=" item" align="left" />
.bigText {
height:30px;
}
Dreamweaver is a poor testing tool. It is not a browser.
When you add an object to $stateProvider.state
that object is then passed with the state. So you can add additional properties which you can read later on when needed.
Example route configuration
$stateProvider
.state('public', {
abstract: true,
module: 'public'
})
.state('public.login', {
url: '/login',
module: 'public'
})
.state('tool', {
abstract: true,
module: 'private'
})
.state('tool.suggestions', {
url: '/suggestions',
module: 'private'
});
The $stateChangeStart
event gives you acces to the toState
and fromState
objects. These state objects will contain the configuration properties.
Example check for the custom module property
$rootScope.$on('$stateChangeStart', function(e, toState, toParams, fromState, fromParams) {
if (toState.module === 'private' && !$cookies.Session) {
// If logged out and transitioning to a logged in page:
e.preventDefault();
$state.go('public.login');
} else if (toState.module === 'public' && $cookies.Session) {
// If logged in and transitioning to a logged out page:
e.preventDefault();
$state.go('tool.suggestions');
};
});
I didn't change the logic of the cookies because I think that is out of scope for your question.
You can create a Helper to get you this to work more modular.
Value publicStates
myApp.value('publicStates', function(){
return {
module: 'public',
routes: [{
name: 'login',
config: {
url: '/login'
}
}]
};
});
Value privateStates
myApp.value('privateStates', function(){
return {
module: 'private',
routes: [{
name: 'suggestions',
config: {
url: '/suggestions'
}
}]
};
});
The Helper
myApp.provider('stateshelperConfig', function () {
this.config = {
// These are the properties we need to set
// $stateProvider: undefined
process: function (stateConfigs){
var module = stateConfigs.module;
$stateProvider = this.$stateProvider;
$stateProvider.state(module, {
abstract: true,
module: module
});
angular.forEach(stateConfigs, function (route){
route.config.module = module;
$stateProvider.state(module + route.name, route.config);
});
}
};
this.$get = function () {
return {
config: this.config
};
};
});
Now you can use the helper to add the state configuration to your state configuration.
myApp.config(['$stateProvider', '$urlRouterProvider',
'stateshelperConfigProvider', 'publicStates', 'privateStates',
function ($stateProvider, $urlRouterProvider, helper, publicStates, privateStates) {
helper.config.$stateProvider = $stateProvider;
helper.process(publicStates);
helper.process(privateStates);
}]);
This way you can abstract the repeated code, and come up with a more modular solution.
Note: the code above isn't tested
Your select count and select max should be from your table variable instead of the actual table
DECLARE @i int

Initially when i implemented a longClick and a click to perform two separate events the problem i face was that when i had a longclick , the application also performed the action to be performed for a simple click . The solution i realized was to change the return type of the longClick to true which is normally false by default . Change it and it works perfectly .
As for today (2011-04-05, updated 2017-11-29) you will need the lastest versions of:
After that, do a full install in a directory of your preference without spaces in the name. I suggest C:\GnuWin32
. Do not install it in the default (C:\Program Files (x86)\GnuWin32) because bison has problems with spaces in directory names, not to say parenthesis.
Also, consider installing Dev-CPP in the default directory (C:\Dev-Cpp
)
After that, set the PATH variable to include the bin directories of gcc
(in C:\Dev-Cpp\bin
) and flex\bison
(in C:\GnuWin32\bin
). To do that, copy this: ;C:\Dev-Cpp\bin;C:\GnuWin32\bin
and append it to the end of the PATH
variable, defined in the place show by this figure:
If the figure is not in good resolution, you can see a step-by-step here.
Open a prompt, cd to the directory where your ".l" and ".y" are, and compile them with:
flex hello.l
bison -dy hello.y
gcc lex.yy.c y.tab.c -o hello.exe
You will be able to run the program. I made the sources for a simple test (the infamous Hello World
):
%{
#include "y.tab.h"
int yyerror(char *errormsg);
%}
%%
("hi"|"oi")"\n" { return HI; }
("tchau"|"bye")"\n" { return BYE; }
. { yyerror("Unknown char"); }
%%
int main(void)
{
yyparse();
return 0;
}
int yywrap(void)
{
return 0;
}
int yyerror(char *errormsg)
{
fprintf(stderr, "%s\n", errormsg);
exit(1);
}
%{
#include <stdio.h>
#include <stdlib.h>
int yylex(void);
int yyerror(const char *s);
%}
%token HI BYE
%%
program:
hi bye
;
hi:
HI { printf("Hello World\n"); }
;
bye:
BYE { printf("Bye World\n"); exit(0); }
;
Edited: avoiding "warning: implicit definition of yyerror and yylex".

Happy hacking.
See this answer: Source
If timezone is not specified in postgresql.conf or as a server command-line option, the server attempts to use the value of the TZ environment variable as the default time zone. If TZ is not defined or is not any of the time zone names known to PostgreSQL, the server attempts to determine the operating system's default time zone by checking the behavior of the C library function localtime(). The default time zone is selected as the closest match among PostgreSQL's known time zones. (These rules are also used to choose the default value of log_timezone, if not specified.) source
This means that if you do not define a timezone, the server attempts to determine the operating system's default time zone by checking the behavior of the C library function localtime().
If timezone is not specified in postgresql.conf or as a server command-line option, the server attempts to use the value of the TZ environment variable as the default time zone.
It seems to have the System's timezone to be set is possible indeed.
Get the OS local time zone from the shell. In psql:
=> \! date +%Z
If you're only wanting the magnifing glass on hover then you can use
a:hover img { cursor: url(glass.cur); }
http://www.javascriptkit.com/dhtmltutors/csscursors.shtml
If you want it there permanently you should probably either have it included in the original thumnail, or add it using JavaScript rather than adding it to the HTML (this is purely style and shouldn't be in the content).
Let me know if you want help on the JavaScript side.
The accepted answer worked for me, but I needed to dig a little deeper to fix the problems with the back button.
What I noticed is that if I link to a page using <a ui-sref="page({x: 1})">
, then remove the query string using $location.search('x', null)
, I don't get an extra entry in my browser history, so the back button takes me back to where I started. Although I feel like this is wrong because I don't think that Angular should automatically remove this history entry for me, this is actually the desired behaviour for my particular use-case.
The problem is that if I link to the page using <a href="/page/?x=1">
instead, then remove the query string in the same way, I do get an extra entry in my browser history, so I have to click the back button twice to get back to where I started. This is inconsistent behaviour, but actually this seems more correct.
I can easily fix the problem with href
links by using $location.search('x', null).replace()
, but then this breaks the page when you land on it via a ui-sref
link, so this is no good.
After a lot of fiddling around, this is the fix I came up with:
In my app's run
function I added this:
$rootScope.$on('$locationChangeSuccess', function () {
$rootScope.locationPath = $location.path();
});
Then I use this code to remove the query string parameter:
$location.search('x', null);
if ($location.path() === $rootScope.locationPath) {
$location.replace();
}
Simplest and quickest way to find where all the time is going.
1. pip install snakeviz
2. python -m cProfile -o temp.dat <PROGRAM>.py
3. snakeviz temp.dat
Draws a pie chart in a browser. Biggest piece is the problem function. Very simple.
I've figured out a solution that worked for me...
If you have a list item (or div) containing only the link, and let's say this is for social links on your page to facebook, twitter, ect. and you're using a sprite image you can do this:
<li id="facebook"><a href="facebook.com"></a></li>
Make the "li"s background your button image
#facebook {
width:30px;
height:30px;
background:url(images/social) no-repeat 0px 0px;
}
Then make the link's background image the hover state of the button. Also add the opacity attribute to this and set it to 0.
#facebook a {
display:inline-block;
background:url(images/social) no-repeat 0px -30px;
opacity:0;
}
Now all you need is "opacity" under "a:hover" and set this to 1.
#facebook a:hover {
opacity:1;
}
Add the opacity transition attributes for each browser to "a" and "a:hover" so the the final css will look something like this:
#facebook {
width:30px;
height:30px;
background:url(images/social) no-repeat 0px 0px;
}
#facebook a {
display:inline-block;
background:url(images/social) no-repeat 0px -30px;
opacity:0;
-webkit-transition: opacity 200ms linear;
-moz-transition: opacity 200ms linear;
-o-transition: opacity 200ms linear;
-ms-transition: opacity 200ms linear;
transition: opacity 200ms linear;
}
#facebook a:hover {
opacity:1;
-webkit-transition: opacity 200ms linear;
-moz-transition: opacity 200ms linear;
-o-transition: opacity 200ms linear;
-ms-transition: opacity 200ms linear;
transition: opacity 200ms linear;
}
If I explained it correctly that should let you have a fading background image button, hope it helps at least!
In addition to using an map-like object, there has been an actual Map
object for some time now, which is available in TypeScript when compiling to ES6, or when using a polyfill with the ES6 type-definitions:
let people = new Map<string, Person>();
It supports the same functionality as Object
, and more, with a slightly different syntax:
// Adding an item (a key-value pair):
people.set("John", { firstName: "John", lastName: "Doe" });
// Checking for the presence of a key:
people.has("John"); // true
// Retrieving a value by a key:
people.get("John").lastName; // "Doe"
// Deleting an item by a key:
people.delete("John");
This alone has several advantages over using a map-like object, such as:
Object
(no, Object
does not support numbers, it converts them to strings)--noImplicitAny
, as a Map
always has a key type and a value type, whereas an object might not have an index-signatureObject
Additionally, a Map
object provides a more powerful and elegant API for common tasks, most of which are not available through simple Object
s without hacking together helper functions (although some of these require a full ES6 iterator/iterable polyfill for ES5 targets or below):
// Iterate over Map entries:
people.forEach((person, key) => ...);
// Clear the Map:
people.clear();
// Get Map size:
people.size;
// Extract keys into array (in insertion order):
let keys = Array.from(people.keys());
// Extract values into array (in insertion order):
let values = Array.from(people.values());
