There are two properties in a TabControl control that manages which tab page is selected.
SelectedIndex which offer the possibility to select it by index (an integer starting from 0 to the number of tabs you have minus one).
SelectedTab which offer the possibility to selected the tab object itself to select.
Setting either of these property will change the currently displayed tab.
Alternatively you can also use the Select method. It comes in three flavour, one where you pass the index of the tab, another the TabPage object itself and the last one a string representing the tab's name.
To check if a specific tab page is the currently selected page of a tab control is easy; just use the SelectedTab property of the tab control:
if (tabControl1.SelectedTab == someTabPage)
{
// Do stuff here...
}
This is more useful if the code is executed based on some event other than the tab page being selected (in which case SelectedIndexChanged would be a better choice).
For example I have an application that uses a timer to regularly poll stuff over TCP/IP connection, but to avoid unnecessary TCP/IP traffic I only poll things that update GUI controls in the currently selected tab page.
This is an old question, but someone may benefit from my addition. I needed a TabControl that would show hidden tabs successively (after an action was performed on the current tab). So, I made a quick class to inherit from and called HideSuccessive() on Load:
public class RevealingTabControl : TabControl
{
private Action _showNextRequested = delegate { };
public void HideSuccessive()
{
var tabPages = this.TabPages.Cast<TabPage>().Skip(1);
var queue = new ConcurrentQueue<TabPage>(tabPages);
tabPages.ToList().ForEach(t => t.Parent = null);
_showNextRequested = () =>
{
if (queue.TryDequeue(out TabPage tabPage))
tabPage.Parent = this;
};
}
public void ShowNext() => _showNextRequested();
}
public static Action<Func<TabPage, bool>> GetTabHider(this TabControl container) {
if (container == null) throw new ArgumentNullException("container");
var orderedCache = new List<TabPage>();
var orderedEnumerator = container.TabPages.GetEnumerator();
while (orderedEnumerator.MoveNext()) {
var current = orderedEnumerator.Current as TabPage;
if (current != null) {
orderedCache.Add(current);
}
}
return (Func<TabPage, bool> where) => {
if (where == null) throw new ArgumentNullException("where");
container.TabPages.Clear();
foreach (TabPage page in orderedCache) {
if (where(page)) {
container.TabPages.Add(page);
}
}
};
}
Used like this:
var showOnly = this.TabContainer1.GetTabHider();
showOnly((tab) => tab.Text != "tabPage1");
Original ordering is retained by retaining a reference to the anonymous function instance.
+1 for microsoft :-) .
I managed to do it this way:
(it assumes you have a Next
button that displays the next TabPage - tabSteps
is the name of the Tab control)
At start up, save all the tabpages in a proper list.
When user presses Next
button, remove all the TabPages in the tab control, then add that with the proper index:
int step = -1;
List<TabPage> savedTabPages;
private void FMain_Load(object sender, EventArgs e) {
// save all tabpages in the list
savedTabPages = new List<TabPage>();
foreach (TabPage tp in tabSteps.TabPages) {
savedTabPages.Add(tp);
}
SelectNextStep();
}
private void SelectNextStep() {
step++;
// remove all tabs
for (int i = tabSteps.TabPages.Count - 1; i >= 0 ; i--) {
tabSteps.TabPages.Remove(tabSteps.TabPages[i]);
}
// add required tab
tabSteps.TabPages.Add(savedTabPages[step]);
}
private void btnNext_Click(object sender, EventArgs e) {
SelectNextStep();
}
Update
public class TabControlHelper {
private TabControl tc;
private List<TabPage> pages;
public TabControlHelper(TabControl tabControl) {
tc = tabControl;
pages = new List<TabPage>();
foreach (TabPage p in tc.TabPages) {
pages.Add(p);
}
}
public void HideAllPages() {
foreach(TabPage p in pages) {
tc.TabPages.Remove(p);
}
}
public void ShowAllPages() {
foreach (TabPage p in pages) {
tc.TabPages.Add(p);
}
}
public void HidePage(TabPage tp) {
tc.TabPages.Remove(tp);
}
public void ShowPage(TabPage tp) {
tc.TabPages.Add(tp);
}
}
If you're using the MVVM pattern then it is inconvenient (and breaks the pattern) to use the event handler. Instead, you can bind each individual TabItem's Selector.IsSelected
property to a dependency property in your viewmodel and then handle the PropertyChanged
event handler. That way you know exactly which tab was selected/deselected based on the PropertyName
and you have a special handler for each tab.
Example: MainView.xaml
<TabControl>
<TabItem Header="My tab 1" Selector.IsSelected="{Binding IsMyTab1Selected}"> ... </TabItem>
<TabItem Header="My tab 2" Selector.IsSelected="{Binding IsMyTab2Selected}"> ... </TabItem>
</TabControl>
Example: MainViewModel.cs
public bool IsMyTab1Selected {
get { return (bool)GetValue(IsMyTab1SelectedProperty); }
set { SetValue(IsMyTab1SelectedProperty, value); }
}
public static readonly DependencyProperty IsMyTab1SelectedProperty =
DependencyProperty.Register("IsMyTab1Selected", typeof(bool), typeof(MainViewModel), new PropertyMetadata(true, new PropertyChangedCallback(MyPropertyChanged)));
public bool IsMyTab2Selected {
get { return (bool)GetValue(IsMyTab2SelectedProperty); }
set { SetValue(IsMyTab2SelectedProperty, value); }
}
public static readonly DependencyProperty IsMyTab2SelectedProperty =
DependencyProperty.Register("IsMyTab2Selected", typeof(bool), typeof(MainViewModel), new PropertyMetadata(false, new PropertyChangedCallback(MyPropertyChanged)));
private void MyPropertyChanged(DependencyObject d, DependencyPropertyChangedEventArgs e) {
if (e.Property.Name == "IsMyTab1Selected") {
// stuff to do
} else if (e.Property.Name == "IsMyTab2Selected") {
// stuff to do
}
}
If your MainViewModel
is INotifyPropertyChanged
rather than DependencyObject
, then use this instead:
Example: MainViewModel.cs
public event PropertyChangedEventHandler PropertyChanged;
protected virtual void OnPropertyChanged(string propertyName) {
PropertyChanged?.Invoke(this, new PropertyChangedEventArgs(propertyName));
}
public MainViewModel() {
PropertyChanged += handlePropertyChanged;
}
public bool IsMyTab1Selected {
get { return _IsMyTab1Selected ; }
set {
if (value != _IsMyTab1Selected ) {
_IsMyTab1Selected = value;
OnPropertyChanged("IsMyTab1Selected ");
}
}
}
private bool _IsMyTab1Selected = false;
public bool IsMyTab2Selected {
get { return _IsMyTab2Selected ; }
set {
if (value != _IsMyTab2Selected ) {
_IsMyTab2Selected = value;
OnPropertyChanged("IsMyTab2Selected ");
}
}
}
private bool _IsMyTab2Selected = false;
private void handlePropertyChanged(object sender, PropertyChangedEventArgs e) {
if (e.PropertyName == "IsMyTab1Selected") {
// stuff to do
} else if (e.PropertyName == "IsMyTab2Selected") {
// stuff to do
}
}
While searching for a way to round tabs, I found Carlo's answer and it did help but I needed a bit more. Here is what I put together, based on his work. This was done with MS Visual Studio 2015.

Screenshot:
I would write the Item names in the summay.. so by hovering over the function helloworld() the text will say hello = Item1 and world = Item2
helloworld("Hi1,Hi2");
/// <summary>
/// Return hello = Item1 and world Item2
/// </summary>
/// <param name="input">string to split</param>
/// <returns></returns>
private static Tuple<bool, bool> helloworld(string input)
{
bool hello = false;
bool world = false;
foreach (var hw in input.Split(','))
{
switch (hw)
{
case "Hi1":
hello= true;
break;
case "Hi2":
world= true;
break;
}
}
return new Tuple<bool, bool>(hello, world);
}
Heres a Swift version:
// MARK: Gesture Extensions
extension UIView {
func addTapGesture(#tapNumber: Int, target: AnyObject, action: Selector) {
let tap = UITapGestureRecognizer (target: target, action: action)
tap.numberOfTapsRequired = tapNumber
addGestureRecognizer(tap)
userInteractionEnabled = true
}
func addTapGesture(#tapNumber: Int, action: ((UITapGestureRecognizer)->())?) {
let tap = BlockTap (tapCount: tapNumber, fingerCount: 1, action: action)
addGestureRecognizer(tap)
userInteractionEnabled = true
}
}
Or
help(list.append)
if you're generally poking around.
You are passing floats to a classifier which expects categorical values as the target vector. If you convert it to int
it will be accepted as input (although it will be questionable if that's the right way to do it).
It would be better to convert your training scores by using scikit's labelEncoder
function.
The same is true for your DecisionTree and KNeighbors qualifier.
from sklearn import preprocessing
from sklearn import utils
lab_enc = preprocessing.LabelEncoder()
encoded = lab_enc.fit_transform(trainingScores)
>>> array([1, 3, 2, 0], dtype=int64)
print(utils.multiclass.type_of_target(trainingScores))
>>> continuous
print(utils.multiclass.type_of_target(trainingScores.astype('int')))
>>> multiclass
print(utils.multiclass.type_of_target(encoded))
>>> multiclass
Another way is to use the -t
switch to ssh
:
ssh -t user@server "sudo script"
See man ssh
:
-t Force pseudo-tty allocation. This can be used to execute arbi-
trary screen-based programs on a remote machine, which can be
very useful, e.g., when implementing menu services. Multiple -t
options force tty allocation, even if ssh has no local tty.
Docker Compose has been updated. They now have a version 2 file format.
Version 2 files are supported by Compose 1.6.0+ and require a Docker Engine of version 1.10.0+.
They now support the networking feature of Docker which when run sets up a default network called myapp_default
From their documentation your file would look something like the below:
version: '2'
services:
web:
build: .
ports:
- "8000:8000"
fpm:
image: phpfpm
nginx
image: nginx
As these containers are automatically added to the default myapp_default network they would be able to talk to each other. You would then have in the Nginx config:
fastcgi_pass fpm:9000;
Also as mentioned by @treeface in the comments remember to ensure PHP-FPM is listening on port 9000, this can be done by editing /etc/php5/fpm/pool.d/www.conf
where you will need listen = 9000
.
I have kept the below here for those using older version of Docker/Docker compose and would like the information.
I kept stumbling upon this question on google when trying to find an answer to this question but it was not quite what I was looking for due to the Q/A emphasis on docker-compose (which at the time of writing only has experimental support for docker networking features). So here is my take on what I have learnt.
Docker has recently deprecated its link feature in favour of its networks feature
Therefore using the Docker Networks feature you can link containers by following these steps. For full explanations on options read up on the docs linked previously.
First create your network
docker network create --driver bridge mynetwork
Next run your PHP-FPM container ensuring you open up port 9000 and assign to your new network (mynetwork
).
docker run -d -p 9000 --net mynetwork --name php-fpm php:fpm
The important bit here is the --name php-fpm
at the end of the command which is the name, we will need this later.
Next run your Nginx container again assign to the network you created.
docker run --net mynetwork --name nginx -d -p 80:80 nginx:latest
For the PHP and Nginx containers you can also add in --volumes-from
commands etc as required.
Now comes the Nginx configuration. Which should look something similar to this:
server {
listen 80;
server_name localhost;
root /path/to/my/webroot;
index index.html index.htm index.php;
location / {
try_files $uri $uri/ /index.php?$query_string;
}
location ~ \.php$ {
fastcgi_split_path_info ^(.+\.php)(/.+)$;
fastcgi_pass php-fpm:9000;
fastcgi_index index.php;
include fastcgi_params;
}
}
Notice the fastcgi_pass php-fpm:9000;
in the location block. Thats saying contact container php-fpm
on port 9000
. When you add containers to a Docker bridge network they all automatically get a hosts file update which puts in their container name against their IP address. So when Nginx sees that it will know to contact the PHP-FPM container you named php-fpm
earlier and assigned to your mynetwork
Docker network.
You can add that Nginx config either during the build process of your Docker container or afterwards its up to you.
The problem is how you've attached the listener:
<input type="checkbox" ... onchange="doalert(this.id)">
Inline listeners are effectively wrapped in a function which is called with the element as this. That function then calls the doalert function, but doesn't set its this so it will default to the global object (window in a browser).
Since the window object doesn't have a checked property, this.checked
always resolves to false.
If you want this within doalert to be the element, attach the listener using addEventListener:
window.onload = function() {
var input = document.querySelector('#g01-01');
if (input) {
input.addEventListener('change', doalert, false);
}
}
Or if you wish to use an inline listener:
<input type="checkbox" ... onchange="doalert.call(this, this.id)">
First use pkill
or kill -9 <pid>
to kill the process.
Then use following userdel
command to delete user,
userdel -f cafe_fixer
According to userdel
man page:
-f, --force
This option forces the removal of the user account, even if the user is still logged in. It also forces userdel to remove the user's home directory and mail spool, even if another user uses the same home directory or if the mail spool is not owned by the specified user. If USERGROUPS_ENAB is defined to yes in /etc/login.defs and if a group exists with the same name as the deleted user, then this group will be removed, even if it is still the primary group of another user.
Edit 1: (by @Ajedi32)
Note: This option (i.e. --force
) is dangerous and may leave your system in an inconsistent state.
Edit 2: (by @socketpair)
In spite of the description about some files, this key allows removing the user while it is in use. Don't forget to chdir /
before, because this command will also remove home directory.
This feature is built into jqGrid.
setup your grid function as follows.
$('#myGrid').jqGrid({
...
colNames: ['Manager', 'Name', 'HiddenSalary'],
colModel: [
{ name: 'Manager', editable: true },
{ name: 'Price', editable: true },
{ name: 'HiddenSalary', hidden: true , editable: true,
editrules: {edithidden:true}
}
],
...
};
There are other editrules that can be applied but this basic setup would hide the manager's salary in the grid view but would allow editing when the edit form was displayed.
We had the same problem for accepting monetary values for Euro, since <input type="number" />
can't display Euro decimal and comma format.
We came up with a solution, to use <input type="number" />
for user input. After user types in the value, we format it and display as a Euro format by just switching to <input type="text" />
. This is a Javascript solution though, cuz you need a condition to decide between "user is typing" and "display to user" modes.
Here the link with Visuals to our solution: Input field type "Currency" problem solved
Hope this helps in some way!
There are multiple options available for generating HTML reports for Selenium WebDriver scripts.
1. Use the JUNIT TestWatcher class for creating your own Selenium HTML reports
The TestWatcher JUNIT class allows overriding the failed() and succeeded() JUNIT methods that are called automatically when JUNIT tests fail or pass.
The TestWatcher JUNIT class allows overriding the following methods:
failed() method is invoked when a test fails
finished() method is invoked when a test method finishes (whether passing or failing)
skipped() method is invoked when a test is skipped due to a failed assumption.
starting() method is invoked when a test is about to start
succeeded() method is invoked when a test succeeds
See below sample code for this case:
import static org.junit.Assert.assertTrue;
import org.junit.Test;
public class TestClass2 extends WatchManClassConsole {
@Test public void testScript1() {
assertTrue(1 < 2); >
}
@Test public void testScript2() {
assertTrue(1 > 2);
}
@Test public void testScript3() {
assertTrue(1 < 2);
}
@Test public void testScript4() {
assertTrue(1 > 2);
}
}
import org.junit.Rule;
import org.junit.rules.TestRule;
import org.junit.rules.TestWatcher;
import org.junit.runner.Description;
import org.junit.runners.model.Statement;
public class WatchManClassConsole {
@Rule public TestRule watchman = new TestWatcher() {
@Override public Statement apply(Statement base, Description description) {
return super.apply(base, description);
}
@Override protected void succeeded(Description description) {
System.out.println(description.getDisplayName() + " " + "success!");
}
@Override protected void failed(Throwable e, Description description) {
System.out.println(description.getDisplayName() + " " + e.getClass().getSimpleName());
}
};
}
2. Use the Allure Reporting framework
Allure framework can help with generating HTML reports for your Selenium WebDriver projects.
The reporting framework is very flexible and it works with many programming languages and unit testing frameworks.
You can read everything about it at http://allure.qatools.ru/.
You will need the following dependencies and plugins to be added to your pom.xml file
See more details including code samples on this article: http://test-able.blogspot.com/2015/10/create-selenium-html-reports-with-allure-framework.html
When to use extends and super
Wildcards are most useful in method parameters. They allow for the necessary flexibility in method interfaces.
People are often confused when to use extends and when to use super bounds. The rule of thumb is the get-put principle. If you get something from a parametrized container, use extends.
int totalFuel(List<? extends Vehicle> list) {
int total = 0;
for(Vehicle v : list) {
total += v.getFuel();
}
return total;}
The method totalFuel gets Vehicles from the list, asks them about how much fuel they have, and computes the total. If you put objects into a parameterized container, use super.
int totalValue(Valuer<? super Vehicle> valuer) {
int total = 0;
for(Vehicle v : vehicles) {
total += valuer.evaluate(v);
}
return total;}
The method totalValue puts Vehicles into the Valuer. It's useful to know that extends bound is much more common than super.
What I have learned from every answer and visiting the blog is
what is the cross axis and main axis
flex-direction: row
flex-direction: column
Now align-content and align-items
align-content is for the row, it works if the container has (more than one row) Properties of align-content
.container {
align-content: flex-start | flex-end | center | space-between | space-around | space-evenly | stretch | start | end | baseline | first baseline | last baseline + ... safe | unsafe;
}
align-items is for the items in row Properties of align-items
.container {
align-items: stretch | flex-start | flex-end | center | baseline | first baseline | last baseline | start | end | self-start | self-end + ... safe | unsafe;
}

If running Windows 10:
path
If on older Windows:
Show Desktop.
Right Click My Computer shortcut in the desktop.
Click Properties.
You should see a section of control Panel - Control Panel\System and Security\System.
Click Advanced System Settings on the Left menu.
Click Enviornment Variables towards the bottom of the System Properties window.
Select PATH in the user variables list.
Append your PHP Path (C:\myfolder\php) to your PATH variable, separated from the already existing string by a semi colon.
Click OK
Open your "cmd"
Type PATH, press enter
Make sure that you see your PHP folder among the list.
That should work.
Note: Make sure that your PHP folder has the php.exe. It should have the file type CLI. If you do not have the php.exe, go ahead and check the installation guidelines at - http://www.php.net/manual/en/install.windows.manual.php - and download the installation file from there.
I just got this and solved it locally on my mac. For some reason the javascript file in question had bad permissions. I noticed when I looked at it in firebug I was getting a 403. I hope that helps anyone.
That's compiled code, you'll need to use a decompiler like JAD: http://www.kpdus.com/jad.html
func callForMenuView() {
if(!isOpen)
{
isOpen = true
let menuVC : MenuViewController = self.storyboard!.instantiateViewController(withIdentifier: "menu") as! MenuViewController
self.view.addSubview(menuVC.view)
self.addChildViewController(menuVC)
menuVC.view.layoutIfNeeded()
menuVC.view.frame=CGRect(x: 0 - UIScreen.main.bounds.size.width, y: 0, width: UIScreen.main.bounds.size.width-90, height: UIScreen.main.bounds.size.height);
UIView.animate(withDuration: 0.3, animations: { () -> Void in
menuVC.view.frame=CGRect(x: 0, y: 0, width: UIScreen.main.bounds.size.width-90, height: UIScreen.main.bounds.size.height);
}, completion:nil)
}else if(isOpen)
{
isOpen = false
let viewMenuBack : UIView = view.subviews.last!
UIView.animate(withDuration: 0.3, animations: { () -> Void in
var frameMenu : CGRect = viewMenuBack.frame
frameMenu.origin.x = -1 * UIScreen.main.bounds.size.width
viewMenuBack.frame = frameMenu
viewMenuBack.layoutIfNeeded()
viewMenuBack.backgroundColor = UIColor.clear
}, completion: { (finished) -> Void in
viewMenuBack.removeFromSuperview()
})
}
search property of type URLSearchParams in RequestOptions class is deprecated in angular 4. Instead, you should use params property of type URLSearchParams.
the other way to exchange data from php to javascript or vice versa is by using cookies, you can save cookies in php and read by your javascript, for this you don't have to use forms or ajax
As others have mentioned the Lint warning is because of the potential memory leak. You can avoid the Lint warning by passing a Handler.Callback
when constructing Handler
(i.e. you don't subclass Handler
and there is no Handler
non-static inner class):
Handler mIncomingHandler = new Handler(new Handler.Callback() {
@Override
public boolean handleMessage(Message msg) {
// todo
return true;
}
});
As I understand it, this will not avoid the potential memory leak. Message
objects hold a reference to the mIncomingHandler
object which holds a reference the Handler.Callback
object which holds a reference to the Service
object. As long as there are messages in the Looper
message queue, the Service
will not be GC. However, it won't be a serious issue unless you have long delay messages in the message queue.
Open SVG using any text editor and remove width
and height
attributes from the root node.
Before
<svg width="12px" height="20px" viewBox="0 0 12 20" ...
After
<svg viewBox="0 0 12 20" ...
Now the image will always fill all the available space and will scale using CSS width
and height
. It will not stretch though so it will only grow to available space.
This solution will change the git file permissions from 100755 to 100644 and push changes back to the bitbucket remote repo.
Take a look at your repo's file permissions: git ls-files --stage
If 100755 and you want 100644
Then run this command: git ls-files --stage | sed 's/\t/ /g' | cut -d' ' -f4 | xargs git update-index --chmod=-x
Now check your repo's file permissions again: git ls-files --stage
Now commit your changes:
git status
git commit -m "restored proper file permissions"
git push
Follwing the below steps you well get package.json file.
npm --version
npm install express
npm init -y

EDIT: commented the R=301
parts because, as explained in a comment:
Be careful with that
R=301
! Having it there makes many browsers cache the .htaccess-file indefinitely: It somehow becomes irreversible if you can't clear the browser-cache on all machines that opened it. When testing, better go with simpleR

After you've completed your tests, you can use R=301

The simplest solution:
POSIX is:
POSIX (pronounced /'p?z?ks/) or "Portable Operating System Interface [for Unix]"1 is the name of a family of related standards specified by the IEEE to define the application programming interface (API), along with shell and utilities interfaces for software compatible with variants of the Unix operating system, although the standard can apply to any operating system.
Basically it was a set of measures to ease the pain of development and usage of different flavours of UNIX by having a (mostly) common API and utilities. Limited POSIX compliance also extended to various versions of Windows.
I was having this issue while running a SpringBoot project (Maven)
In my POM file I changed the java version from 11 to 8 and it worked:
<properties>
<java.version>8</java.version> //The default was 11
</properties>
Make sure to Load maven changes
else the change won't reflect.
How about
[@"7" intValue];
Additionally if you want an NSNumber
you could do
NSNumberFormatter *numberFormatter = [[NSNumberFormatter alloc] init];
[numberFormatter numberFromString:@"7"];
If you were to do the following:
<li class="active-item" ng-repeat="item in mc.pageData.items | filter: { itemTypeId: 2, itemStatus: 1 } | orderBy : 'listIndex'"
id="{{item.id}}">
<span class="item-title">{{preference.itemTitle}}</span>
</li>
...you would not only get items of itemTypeId 2 and itemStatus 1, but you would also get items with itemType 20, 22, 202, 123 and itemStatus 10, 11, 101, 123. This is because the filter: {...} syntax works like a string contains query.
However, if you were to add the : true condition, it would do filter by exact match:
<li class="active-item" ng-repeat="item in mc.pageData.items | filter: { itemTypeId: 2, itemStatus: 1 } : true | orderBy : 'listIndex'"
id="{{item.id}}">
<span class="item-title">{{preference.itemTitle}}</span>
</li>
other = s or "some default value"
Ok, it must be clarified how the or
operator works. It is a boolean operator, so it works in a boolean context. If the values are not boolean, they are converted to boolean for the purposes of the operator.
Note that the or
operator does not return only True
or False
. Instead, it returns the first operand if the first operand evaluates to true, and it returns the second operand if the first operand evaluates to false.
In this case, the expression x or y
returns x
if it is True
or evaluates to true when converted to boolean. Otherwise, it returns y
. For most cases, this will serve for the very same purpose of C?'s null-coalescing operator, but keep in mind:
42 or "something" # returns 42
0 or "something" # returns "something"
None or "something" # returns "something"
False or "something" # returns "something"
"" or "something" # returns "something"
If you use your variable s
to hold something that is either a reference to the instance of a class or None
(as long as your class does not define members __nonzero__()
and __len__()
), it is secure to use the same semantics as the null-coalescing operator.
In fact, it may even be useful to have this side-effect of Python. Since you know what values evaluates to false, you can use this to trigger the default value without using None
specifically (an error object, for example).
In some languages this behavior is referred to as the Elvis operator.
Create a file named .gitignore
in your project's directory. Ignore directories by entering the directory name into the file (with a slash appended):
dir_to_ignore/

I also had this question. tabPage.Visible is not implemented as stated earlier, which was a great help (+1). I found you can override the control and this will work. A bit of necroposting, but I thought to post my solution here for others...
[System.ComponentModel.DesignerCategory("Code")]
public class MyTabPage : TabPage
{
private TabControl _parent;
private bool _isVisible;
private int _index;
public new bool Visible
{
get { return _isVisible; }
set
{
if (_parent == null) _parent = this.Parent as TabControl;
if (_parent == null) return;
if (_index < 0) _index = _parent.TabPages.IndexOf(this);
if (value && !_parent.TabPages.Contains(this))
{
if (_index > 0) _parent.TabPages.Insert(_index, this);
else _parent.TabPages.Add(this);
}
else if (!value && _parent.TabPages.Contains(this)) _parent.TabPages.Remove(this);
_isVisible = value;
base.Visible = value;
}
}
protected override void InitLayout()
{
base.InitLayout();
_parent = Parent as TabControl;
}
}

Here is another neat trick to define enum using X Macro:
#include <iostream>
#define WEEK_DAYS \
X(MON, "Monday", true) \
X(TUE, "Tuesday", true) \
X(WED, "Wednesday", true) \
X(THU, "Thursday", true) \
X(FRI, "Friday", true) \
X(SAT, "Saturday", false) \
X(SUN, "Sunday", false)
#define X(day, name, workday) day,
enum WeekDay : size_t
{
WEEK_DAYS
};
#undef X
#define X(day, name, workday) name,
char const *weekday_name[] =
{
WEEK_DAYS
};
#undef X
#define X(day, name, workday) workday,
bool weekday_workday[]
{
WEEK_DAYS
};
#undef X
int main()
{
std::cout << "Enum value: " << WeekDay::THU << std::endl;
std::cout << "Name string: " << weekday_name[WeekDay::THU] << std::endl;
std::cout << std::boolalpha << "Work day: " << weekday_workday[WeekDay::THU] << std::endl;
WeekDay wd = SUN;
std::cout << "Enum value: " << wd << std::endl;
std::cout << "Name string: " << weekday_name[wd] << std::endl;
std::cout << std::boolalpha << "Work day: " << weekday_workday[wd] << std::endl;
return 0;
}

Outputs:
Enum value: 3
Name string: Thursday
Work day: true
Enum value: 6
Name string: Sunday
Work day: false
Apart from the question whether class decorators are the right solution to your problem:
In Python 2.6 and higher, there are class decorators with the @-syntax, so you can write:
@addID
class Foo:
pass
In older versions, you can do it another way:
class Foo:
pass
Foo = addID(Foo)
Note however that this works the same as for function decorators, and that the decorator should return the new (or modified original) class, which is not what you're doing in the example. The addID decorator would look like this:
def addID(original_class):
orig_init = original_class.__init__
# Make copy of original __init__, so we can call it without recursion
def __init__(self, id, *args, **kws):
self.__id = id
self.getId = getId
orig_init(self, *args, **kws) # Call the original __init__
original_class.__init__ = __init__ # Set the class' __init__ to the new one
return original_class
You could then use the appropriate syntax for your Python version as described above.
But I agree with others that inheritance is better suited if you want to override __init__
.
String s = "ABC[This is to extract]";
System.out.println(s);
int startIndex = s.indexOf('[');
System.out.println("indexOf([) = " + startIndex);
int endIndex = s.indexOf(']');
System.out.println("indexOf(]) = " + endIndex);
System.out.println(s.substring(startIndex + 1, endIndex));
First
EXEC sp_fkeys 'Table', 'Schema'
Then use NimbleText to play with your results
The final keyword is used to declare constants.
final int FILE_TYPE = 3;
The finally keyword is used in a try catch statement to specify a block of code to execute regardless of thrown exceptions.
try
{
//stuff
}
catch(Exception e)
{
//do stuff
}
finally
{
//this is always run
}
And finally (haha), finalize im not entirely sure is a keyword, but there is a finalize() function in the Object class.
You can clean up a zombie process by killing its parent process with the following command:
kill -HUP $(ps -A -ostat,ppid | awk '{/[zZ]/{ print $2 }')
Documented couple of design issues with this in a comment above. Short story, in Oracle, you need to limit the results manually when you have large tables and/or tables with same column names (and you don't want to explicit type them all out and rename them all). Easy solution is to figure out your breakpoint and limit that in your query. Or you could also do this in the inner query if you don't have the conflicting column names constraint. E.g.
WHERE m_api_log.created_date BETWEEN TO_DATE('10/23/2015 05:00', 'MM/DD/YYYY HH24:MI')
AND TO_DATE('10/30/2015 23:59', 'MM/DD/YYYY HH24:MI')
will cut down the results substantially. Then you can ORDER BY or even do the outer query to limit rows.
Also, I think TOAD has a feature to limit rows; but, not sure that does limiting within the actual query on Oracle. Not sure.
Combining the answers above, you can implement something that works like the gem colorize without needing another dependency.
class String
# colorization
def colorize(color_code)
"\e[#{color_code}m#{self}\e[0m"
end
def red
colorize(31)
end
def green
colorize(32)
end
def yellow
colorize(33)
end
def blue
colorize(34)
end
def pink
colorize(35)
end
def light_blue
colorize(36)
end
end
Override annotation is used to take advantage of the compiler, for checking whether you actually are overriding a method from parent class. It is used to notify if you make any mistake like mistake of misspelling a method name, mistake of not correctly matching the parameters
I believe you can use a case statement in a where clause, here is how I do it:
Select
ProductID
OrderNo,
OrderType,
OrderLineNo
From Order_Detail
Where ProductID in (
Select Case when (@Varibale1 != '')
then (Select ProductID from Product P Where .......)
Else (Select ProductID from Product)
End as ProductID
)
This method has worked for me time and again. try it!
You should be referencing Selected
not ids.Contains
as the last line.
I just realized this is a formatting issue, from the OP. Regardless you should be referencing the value in Selected. I recommend adding some Console.WriteLine calls to see exactly what is being printed out on each line and also what each value is.
After your update: ids is an empty list, how is this not throwing a NullReferenceException? As it was never initialized in that code block
99% of the time I would use XMLHttpRequest or fetch for something like this. However, there's an alternative solution which doesn't require javascript...
You could include a hidden iframe on your page and set the target attribute of your form to point to that iframe.
<style>
.hide { position:absolute; top:-1px; left:-1px; width:1px; height:1px; }
</style>
<iframe name="hiddenFrame" class="hide"></iframe>
<form action="receiver.pl" method="post" target="hiddenFrame">
<input name="signed" type="checkbox">
<input value="Save" type="submit">
</form>
There are very few scenarios where I would choose this route. Generally handling it with javascript is better because, with javascript you can...
As of Python 3.1, string.translate
and string.maketrans
no longer exist. However, these methods can be used with bytes
instead.
Thus, an up-to-date solution directly inspired from Paul Rubel's one, is:
rot13 = bytes.maketrans(
b"abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ",
b"nopqrstuvwxyzabcdefghijklmNOPQRSTUVWXYZABCDEFGHIJKLM")
b'Hello world!'.translate(rot13)
Conversion from string
to bytes
and vice-versa can be done with the encode
and decode
built-in functions.
According to HTML living standard specification, the load
event is
Fired at the Window when the document has finished loading; fired at an element containing a resource (e.g. img, embed) when its resource has finished loading
I.e. load

object.

You should be denoting the call by reference in the function definition, not the actual call. Since PHP started showing the deprecation errors in version 5.3, I would say it would be a good idea to rewrite the code.
There is no reference sign on a function call - only on function definitions. Function definitions alone are enough to correctly pass the argument by reference. As of PHP 5.3.0, you will get a warning saying that "call-time pass-by-reference" is deprecated when you use
&
infoo(&$a);
.
For example, instead of using:
// Wrong way!
myFunc(&$arg); # Deprecated pass-by-reference argument
function myFunc($arg) { }
Use:
// Right way!
myFunc($var); # pass-by-value argument
function myFunc(&$arg) { }
Setup https://docs.djangoproject.com/en/dev/topics/logging/ and then these error's will echo where you point them. By default they tend to go off in the weeds so I always start off with a good logging setup before anything else.

try {

result = $.parseJSON(JSONstring);
// if plain js
result = JSON.parse(JSONstring);
}
catch(e) {

The route.snapshot provides the initial value of the route parameter map. You can access the parameters directly without subscribing or adding observable operators. It's much simpler to write and read:
Quote from the Angular Docs
To break it down for you, here is how to do it with the new router:
this.router.navigate(['/login'], { queryParams: { token:'1234'} });
And then in the login component (notice the new .snapshot
added):
constructor(private route: ActivatedRoute) {}
ngOnInit() {
this.sessionId = this.route.snapshot.queryParams['token']
}
For me the issue was I had configured another folder under "Run configurations" which had a class without the latest changes. Once I got it removed referred to the correct bin folder, it started working. Hope it helps someone.
Storing yyyy-mm-dd
in MySql Date format you must do the following:
const newDate = new Date( yourDate.getTime() + Math.abs(yourDate.getTimezoneOffset()*60000) );
console.log(newDate.toJSON().slice(0, 10)); // yyyy-mm-dd
Since version 5.6.3 Gradle documentation provides simple rules of thumb to identify whether an old compile
dependency (or a new one) should be replaced with an implementation
or an api
dependency:
- Prefer the
implementation
configuration overapi
when possibleThis keeps the dependencies off of the consumer’s compilation classpath. In addition, the consumers will immediately fail to compile if any implementation types accidentally leak into the public API.
So when should you use the
api
configuration? An API dependency is one that contains at least one type that is exposed in the library binary interface, often referred to as its ABI (Application Binary Interface). This includes, but is not limited to:
- types used in super classes or interfaces
- types used in public method parameters, including generic parameter types (where public is something that is visible to compilers. I.e. , public, protected and package private members in the Java world)
- types used in public fields
- public annotation types
By contrast, any type that is used in the following list is irrelevant to the ABI, and therefore should be declared as an
implementation
dependency:
- types exclusively used in method bodies
- types exclusively used in private members
- types exclusively found in internal classes (future versions of Gradle will let you declare which packages belong to the public API)

Look for the little icon on the very right-hand side of the toolbar that starts with the text "Show output from:" in it. It looks like a small window with a carriage return icon. When you hover over it Visual Studio should display "Toggle Word Wrap" near your mouse pointer.

You now have learned something that was so painfully obvious I feel embarrassed for not knowing this long ago and thus have chosen to pay my dues and share my answer with others so they don't suffer the same agony I have.
Seriously, this is really useful for those with small screens. I have a small Lilliput USB monitor that is good for small tool windows, Skype IM, etc. It works great for putting the output window on, except that it sucks having to always sideways scroll. After just putting up with sideways scroll for months I finally decided to see if I could make it word wrap. The answer was so easy but the amount of time/effort it saves is tremendous.

Here's an example to determine whether a given number is even or odd,
import java.util.Scanner;
public class EvenOdd
{
public static void main(String[] args)
{
int a;
System.out.println("Please enter a number to check even or odd:");
Scanner sc = new Scanner(System.in);
a = sc.nextInt();
if(a % 2 == 0)
{
System.out.println("Entered number is an even number");
}
else
{
System.out.println("Entered number is an odd number");

Well, there are many ways to determine the same. Refer this resource for more examples to find the given number is even or odd.

I copy here the content of a post on my blog
The solution I propose is very simple and easy to implement. Although, it has reached the score of 131040. Several benchmarks of the algorithm performances are presented.
Heuristic scoring algorithm
The assumption on which my algorithm is based is rather simple: if you want to achieve higher score, the board must be kept as tidy as possible. In particular, the optimal setup is given by a linear and monotonic decreasing order of the tile values. This intuition will give you also the upper bound for a tile value: where n is the number of tile on the board.
(There's a possibility to reach the 131072 tile if the 4-tile is randomly generated instead of the 2-tile when needed)
Two possible ways of organizing the board are shown in the following images:
To enforce the ordination of the tiles in a monotonic decreasing order, the score si computed as the sum of the linearized values on the board multiplied by the values of a geometric sequence with common ratio r<1 .
Several linear path could be evaluated at once, the final score will be the maximum score of any path.
Decision rule
The decision rule implemented is not quite smart, the code in Python is presented here:
@staticmethod
def nextMove(board,recursion_depth=3):
m,s = AI.nextMoveRecur(board,recursion_depth,recursion_depth)
return m
@staticmethod
def nextMoveRecur(board,depth,maxDepth,base=0.9):
bestScore = -1.
bestMove = 0
for m in range(1,5):
if(board.validMove(m)):
newBoard = copy.deepcopy(board)
newBoard.move(m,add_tile=True)
score = AI.evaluate(newBoard)
if depth != 0:
my_m,my_s = AI.nextMoveRecur(newBoard,depth-1,maxDepth)
score += my_s*pow(base,maxDepth-depth+1)
if(score > bestScore):
bestMove = m
bestScore = score
return (bestMove,bestScore);
An implementation of the minmax or the Expectiminimax will surely improve the algorithm. Obviously a more sophisticated decision rule will slow down the algorithm and it will require some time to be implemented.I will try a minimax implementation in the near future. (stay tuned)
In case of T2, four tests in ten generate the 4096 tile with an average score of 42000
The code can be found on GiHub at the following link: https://github.com/Nicola17/term2048-AI It is based on term2048 and it's written in Python. I will implement a more efficient version in C++ as soon as possible.
One additional thing I would like to mention that some of the answers may have missed is the downside to having both ETags
and Expires/Cache-control
in your headers.
Depending on your needs it may just add extra bytes in your headers which may increase packets which means more TCP overhead. Again, you should see if the overhead of having both things in your headers is necessary or will it just add extra weight in your requests which reduces performance.
You can read more about it on this excellent blog post by Kyle Simpson: http://calendar.perfplanet.com/2010/bloated-request-response-headers/

set "Package=%Server%\%MSI%\%MSI%.msi"
if not exist "%Package%" (
echo.
echo The entered folder/MSI file does not exist ^(typing mistake^).
echo.
setlocal EnableDelayedExpansion
set /P "Retry=Try again [Y/N]: "
if /I "!Retry!"=="Y" endlocal & goto select
endlocal
goto :EOF
)
echo.
echo Selected installation: %MSI%
echo.
echo.

echo Is This Correct?
echo.
echo.
echo 0: ABORT INSTALL
echo 1: YES
echo 2: NO, RE-SELECT
echo.
set /p "choice=Select YES, NO or ABORT? [0,1,2]: "
if [%choice%]==[0] goto :EOF
if [%choice%]==[1] goto yes

echo Running %MSI% installation ...
start "Install MSI" /wait "%SystemRoot%\system32\msiexec.exe" /i /quiet "%Package%"
The characters listed on last page output on entering in a command prompt window either help cmd
or cmd /?
have special meanings in batch files. Here are used parentheses and square brackets also in strings where those characters should be interpreted literally. Therefore it is necessary to either enclose the string in double quotes or escape those characters with character ^
as it can be seen in code above, otherwise command line interpreter exits batch execution because of a syntax error.
And it is not possible to call a file with extension MSI. A *.msi file is not an executable. On double clicking on a MSI file, Windows looks in registry which application is associated with this file extension for opening action. And the application to use is msiexec
with the command line option /i
to install the application inside MSI package.
Run msiexec.exe /?
to get in a GUI window the available options or look at Msiexec (command-line options).
I have added already /quiet
additionally to required option /i
for a silent installation.
In batch code above command start
is used with option /wait
to start Windows application msiexec.exe
and hold execution of batch file until installation finished (or aborted).
Many people call this a Protocol Relative URL.

}
However, an alternative would be to put the input
inside a div

git clone
is how you get a local copy of an existing repository to work on. It's usually only used once for a given repository, unless you want to have multiple working copies of it around. (Or want to get a clean copy after messing up your local one...)
git pull
(or git fetch
+ git merge
) is how you update that local copy with new commits from the remote repository. If you are collaborating with others, it is a command that you will run frequently.
As your first example shows, it is possible to emulate git clone
with an assortment of other git commands, but it's not really the case that git pull
is doing "basically the same thing" as git clone
(or vice-versa).
Suppose your dataframe is as follows:
>>> df
A B C ID
0 1 3 2 p
1 4 3 2 q
2 4 0 9 r
set_index
to set ID
columns as the dataframe index. df.set_index("ID", drop=True, inplace=True)
orient=index
parameter to have the index as dictionary keys. dictionary = df.to_dict(orient="index")
The results will be as follows:
>>> dictionary
{'q': {'A': 4, 'B': 3, 'D': 2}, 'p': {'A': 1, 'B': 3, 'D': 2}, 'r': {'A': 4, 'B': 0, 'D': 9}}
column_order= ["A", "B", "C"] # Determine your preferred order of columns
d = {} # Initialize the new dictionary as an empty dictionary
for k in dictionary:
d[k] = [dictionary[k][column_name] for column_name in column_order]
&&
works by stringing-together multiple selectors like-so:
<div class="class1 class2"></div>
div.class1.class2
{
/* foo */
}
Another example:
<input type="radio" class="class1" />
input[type="radio"].class1
{
/* foo */
}
||
works by separating multiple selectors with commas like-so:
<div class="class1"></div>
<div class="class2"></div>
div.class1,
div.class2
{
/* foo */
}
Also, if your service is sending an object instead of an array add isArray:false to its declaration.
'query': {method: 'GET', isArray: false }
In your project settings.py file,set ALLOWED_HOSTS like this :
ALLOWED_HOSTS = ['62.63.141.41', 'namjoosadr.com']
and then restart your apache. in ubuntu:
/etc/init.d/apache2 restart
Here is a partial answer that shows the directory names.
ls -mR * | sed -n 's/://p'
Explanation:
ls -mR *
lists the full directory names ending in a ':', then lists the files in that directory separately
sed -n 's/://p'
finds lines that end in a colon, strip off the colon and print the line
By iterating over the list of directories, we should be able to find the directories as well. Still workin on it. It is a challenge to get the wildcards through xargs.
You can use plt.subplots_adjust to change the spacing between the subplots Link
subplots_adjust(left=None, bottom=None, right=None, top=None, wspace=None, hspace=None)
left = 0.125 # the left side of the subplots of the figure
right = 0.9 # the right side of the subplots of the figure
bottom = 0.1 # the bottom of the subplots of the figure
top = 0.9 # the top of the subplots of the figure
wspace = 0.2 # the amount of width reserved for blank space between subplots
hspace = 0.2 # the amount of height reserved for white space between subplots
Well, after searching around and cobbling together various points from around StackOverflow (gee, I love this place already), most of the problems were already past this stage. I did manage to work out an answer to my problem though.
How to create a resource:
In my case, I want to create an icon. It's a similar process, no matter what type of data you want to add as a resource though.
How to use a resource:
Great, so we have our new resource and we're itching to have those lovely changing icons... How do we do that? Well, lucky us, C# makes this exceedingly easy.
There is a static class called Properties.Resources
that gives you access to all your resources, so my code ended up being as simple as:
paused = !paused;
if (paused)
notifyIcon.Icon = Properties.Resources.RedIcon;
else
notifyIcon.Icon = Properties.Resources.GreenIcon;
Done! Finished! Everything is simple when you know how, isn't it?
Increase the value of xdebug.max_nesting_level
in your php.ini
If you use the nextLine() method immediately following the nextInt() method, nextInt() reads integer tokens; because of this, the last newline character for that line of integer input is still queued in the input buffer and the next nextLine() will be reading the remainder of the integer line (which is empty). So we read can read the empty space to another string might work. Check below code.
import java.util.Scanner;
public class Solution {
public static void main(String[] args) {
Scanner scan = new Scanner(System.in);
int i = scan.nextInt();
Double d = scan.nextDouble();
String f = scan.nextLine();
String s = scan.nextLine();
// Write your code here.
System.out.println("String: " + s);
System.out.println("Double: " + d);
System.out.println("Int: " + i);
}
}
Ternary, conditional; tomato, tomatoh. What it's really valuable for is variable initialization. If (like me) you're fond of initializing variables where they are defined, the conditional ternary operator (for it is both) permits you to do that in cases where there is conditionality about its value. Particularly notable in final fields, but useful elsewhere, too.
e.g.:
public class Foo {
final double value;
public Foo(boolean positive, double value) {
this.value = positive ? value : -value;
}
}
Without that operator - by whatever name - you would have to make the field non-final or write a function simply to initialize it. Actually, that's not right - it can still be initialized using if/else, at least in Java. But I find this cleaner.
I want to add that sometimes android studio loses track of the resources file and can't build on launch. If the above answers are to no avail, try

If you want to keep your CustomView
and its xib
independent of File's Owner
, then follow these steps
File's Owner
field empty.xib
file of your CustomView
and set its Custom Class
as CustomView
(name of your custom view class)IBOutlet
in .h
file of your custom view..xib
file of your custom view, click on view and go in Connection Inspector
. Here you will all your IBOutlets which you define in .h
filein .m
file of your CustomView
class, override the init
method as follow
-(CustomView *) init{
CustomView *result = nil;
NSArray* elements = [[NSBundle mainBundle] loadNibNamed: NSStringFromClass([self class]) owner:self options: nil];
for (id anObject in elements)
{
if ([anObject isKindOfClass:[self class]])
{
result = anObject;
break;
}
}
return result;
}
Now when you want to load your CustomView
, use the following line of code
[[CustomView alloc] init];
If you just wanted to check whether flash is enabled, this should be enough.
function testFlash() {
var support = false;
//IE only
if("ActiveXObject" in window) {
try{
support = !!(new ActiveXObject("ShockwaveFlash.ShockwaveFlash"));
}catch(e){
support = false;
}
//W3C, better support in legacy browser
} else {
support = !!navigator.mimeTypes['application/x-shockwave-flash'];
}
return support;
}
Note: avoid checking enabledPlugin, some mobile browser has tap-to-enable flash plugin, and will trigger false negative.
PDFminer gave me perhaps one line [page 1 of 7...] on every page of a pdf file I tried with it.
The best answer I have so far is pdftoipe, or the c++ code it's based on Xpdf.
see my question for what the output of pdftoipe looks like.
I don't think using _ or m_ to indicate member variables is bad in Java or any other language. It my opinion it improves readability of your code because it allows you to look at a snippet and quickly identify out all of the member variables from locals.
You can also achieve this by forcing users to prepend instance variables with "this" but I find this slighly draconian. In many ways it violates DRY because it's an instance variable, why qualify it twice.
My own personal style is to use m_ instead of _. The reason being that there are also global and static variables. The advantage to m_/_ is it distinguishes a variables scope. So you can't reuse _ for global or static and instead I choose g_ and s_ respectively.
This query will list all of the tables in all of the databases and schemas (uncomment the line(s) in the WHERE
clause to filter for specific databases, schemas, or tables), with the privileges shown in order so that it's easy to see if a specific privilege is granted or not:
SELECT grantee
,table_catalog
,table_schema
,table_name
,string_agg(privilege_type, ', ' ORDER BY privilege_type) AS privileges
FROM information_schema.role_table_grants
WHERE grantee != 'postgres'
-- and table_catalog = 'somedatabase' /* uncomment line to filter database */
-- and table_schema = 'someschema' /* uncomment line to filter schema */
-- and table_name = 'sometable' /* uncomment line to filter table */
GROUP BY 1, 2, 3, 4;
Sample output:
grantee |table_catalog |table_schema |table_name |privileges |
--------|----------------|--------------|---------------|---------------|
PUBLIC |adventure_works |pg_catalog |pg_sequence |SELECT |
PUBLIC |adventure_works |pg_catalog |pg_sequences |SELECT |
PUBLIC |adventure_works |pg_catalog |pg_settings |SELECT, UPDATE |

I had this problem in Microsoft Visual Studio 2008 and the solution is easy. when you run your project please set in "Debug" mode not "Release". The another people solution can be useful.

This works for rounding to N digits (if you just want to truncate to N digits remove the Math.round call and use the Math.trunc one):
function roundN(value, digits) {
var tenToN = 10 ** digits;
return /*Math.trunc*/(Math.round(value * tenToN)) / tenToN;
}
Had to resort to such logic at Java in the past when I was authoring data manipulation E-Slate components. That is since I had found out that adding 0.1 many times to 0 you'd end up with some unexpectedly long decimal part (this is due to floating point arithmetics).
A user comment at Format number to always show 2 decimal places calls this technique scaling.
Some mention there are cases that don't round as expected and at http://www.jacklmoore.com/notes/rounding-in-javascript/ this is suggested instead:
function round(value, decimals) {
return Number(Math.round(value+'e'+decimals)+'e-'+decimals);
}
As a representative of HiQPdf Software I believe the best solution is HiQPdf HTML to PDF converter for .NET. It contains the most advanced HTML5, CSS3, SVG and JavaScript rendering engine on market. There is also a free version of the HTML to PDF library which you can use to produce for free up to 3 PDF pages. The minimal C# code to produce a PDF as a byte[] from a HTML page is:
HtmlToPdf htmlToPdfConverter = new HtmlToPdf();
// set PDF page size, orientation and margins
htmlToPdfConverter.Document.PageSize = PdfPageSize.A4;
htmlToPdfConverter.Document.PageOrientation = PdfPageOrientation.Portrait;
htmlToPdfConverter.Document.Margins = new PdfMargins(0);
// convert HTML to PDF
byte[] pdfBuffer = htmlToPdfConverter.ConvertUrlToMemory(url);
You can find more detailed examples both for ASP.NET and MVC in HiQPdf HTML to PDF Converter examples repository.
Try this
var fd = new FormData();
fd.append('fname', 'test.wav');
fd.append('data', soundBlob);
$.ajax({
type: 'POST',
url: '/upload.php',
data: fd,
processData: false,
contentType: false
}).done(function(data) {
console.log(data);
});
You need to use the FormData API and set the jQuery.ajax
's processData
and contentType
to false
.
And just in case, if you want to find the coordinates of 'nan' for all the columns instead (supposing they are all numericals), here you go:
df = pd.DataFrame([[0,1,3,4,np.nan,2],[3,5,6,np.nan,3,3]])
df
0 1 2 3 4 5
0 0 1 3 4.0 NaN 2
1 3 5 6 NaN 3.0 3
np.where(np.asanyarray(np.isnan(df)))
(array([0, 1]), array([4, 3]))
In my case the answer is pretty simple. Please check carefully the hardcoded url port: it is 8080. For some reason the value has changed to: for example 3030.
Just refresh the port in your ajax url string to the appropriate one.
conn = new WebSocket('ws://localhost:3030'); //should solve the issue
The reason eval
and exec
are so dangerous is that the default compile
function will generate bytecode for any valid python expression, and the default eval
or exec
will execute any valid python bytecode. All the answers to date have focused on restricting the bytecode that can be generated (by sanitizing input) or building your own domain-specific-language using the AST.
Instead, you can easily create a simple eval
function that is incapable of doing anything nefarious and can easily have runtime checks on memory or time used. Of course, if it is simple math, than there is a shortcut.
c = compile(stringExp, 'userinput', 'eval')
if c.co_code[0]==b'd' and c.co_code[3]==b'S':
return c.co_consts[ord(c.co_code[1])+ord(c.co_code[2])*256]
The way this works is simple, any constant mathematic expression is safely evaluated during compilation and stored as a constant. The code object returned by compile consists of d
, which is the bytecode for LOAD_CONST
, followed by the number of the constant to load (usually the last one in the list), followed by S
, which is the bytecode for RETURN_VALUE
. If this shortcut doesn't work, it means that the user input isn't a constant expression (contains a variable or function call or similar).
This also opens the door to some more sophisticated input formats. For example:
stringExp = "1 + cos(2)"
This requires actually evaluating the bytecode, which is still quite simple. Python bytecode is a stack oriented language, so everything is a simple matter of TOS=stack.pop(); op(TOS); stack.put(TOS)
or similar. The key is to only implement the opcodes that are safe (loading/storing values, math operations, returning values) and not unsafe ones (attribute lookup). If you want the user to be able to call functions (the whole reason not to use the shortcut above), simple make your implementation of CALL_FUNCTION
only allow functions in a 'safe' list.
from dis import opmap
from Queue import LifoQueue
from math import sin,cos
import operator
globs = {'sin':sin, 'cos':cos}
safe = globs.values()
stack = LifoQueue()
class BINARY(object):
def __init__(self, operator):
self.op=operator
def __call__(self, context):
stack.put(self.op(stack.get(),stack.get()))
class UNARY(object):
def __init__(self, operator):
self.op=operator
def __call__(self, context):
stack.put(self.op(stack.get()))
def CALL_FUNCTION(context, arg):
argc = arg[0]+arg[1]*256
args = [stack.get() for i in range(argc)]
func = stack.get()
if func not in safe:
raise TypeError("Function %r now allowed"%func)
stack.put(func(*args))
def LOAD_CONST(context, arg):
cons = arg[0]+arg[1]*256
stack.put(context['code'].co_consts[cons])
def LOAD_NAME(context, arg):
name_num = arg[0]+arg[1]*256
name = context['code'].co_names[name_num]
if name in context['locals']:
stack.put(context['locals'][name])
else:
stack.put(context['globals'][name])
def RETURN_VALUE(context):
return stack.get()
opfuncs = {
opmap['BINARY_ADD']: BINARY(operator.add),
opmap['UNARY_INVERT']: UNARY(operator.invert),
opmap['CALL_FUNCTION']: CALL_FUNCTION,
opmap['LOAD_CONST']: LOAD_CONST,
opmap['LOAD_NAME']: LOAD_NAME
opmap['RETURN_VALUE']: RETURN_VALUE,
}
def VMeval(c):
context = dict(locals={}, globals=globs, code=c)
bci = iter(c.co_code)
for bytecode in bci:
func = opfuncs[ord(bytecode)]
if func.func_code.co_argcount==1:
ret = func(context)
else:
args = ord(bci.next()), ord(bci.next())
ret = func(context, args)
if ret:
return ret
def evaluate(expr):
return VMeval(compile(expr, 'userinput', 'eval'))
Obviously, the real version of this would be a bit longer (there are 119 opcodes, 24 of which are math related). Adding STORE_FAST
and a couple others would allow for input like 'x=5;return x+x
or similar, trivially easily. It can even be used to execute user-created functions, so long as the user created functions are themselves executed via VMeval (don't make them callable!!! or they could get used as a callback somewhere). Handling loops requires support for the goto
bytecodes, which means changing from a for
iterator to while
and maintaining a pointer to the current instruction, but isn't too hard. For resistance to DOS, the main loop should check how much time has passed since the start of the calculation, and certain operators should deny input over some reasonable limit (BINARY_POWER
being the most obvious).
While this approach is somewhat longer than a simple grammar parser for simple expressions (see above about just grabbing the compiled constant), it extends easily to more complicated input, and doesn't require dealing with grammar (compile
take anything arbitrarily complicated and reduces it to a sequence of simple instructions).
Having just encountered this on Arch Linux 4.13.3, I solved the issue by simply reinstalling semver

pacman -S semver
My app, DropDMG, is an easy way to create disk images with background pictures, icon layouts, custom volume icons, and software license agreements. It can be controlled from a build system via the "dropdmg" command-line tool or AppleScript. If desired, the picture and license RTF files can be stored under your version control system.
You can just go for String

If you are using AngularJS, and you are using Angular Bootstrap : https://angular-ui.github.io/bootstrap/
You can do this so nice like this :
HTML:
<nav id="header-navbar" class="navbar navbar-default" ng-class="{'navbar-fixed-top':scrollDown}" role="navigation" scroll-nav>
<div class="container-fluid top-header">
<!--- Rest of code --->
</div>
</nav>
CSS: (Note here I use padding as bigger nav to shrink without padding you can modify as you want)
nav.navbar {
-webkit-transition: all 0.4s ease;
transition: all 0.4s ease;
background-color: white;
margin-bottom: 0;
padding: 25px;
}
.navbar-fixed-top {
padding: 0;
}
And then add your directive
Directive: (Note you may need to change this.pageYOffset >= 50
from 50 to more or less to fulfill your needs)
angular.module('app')
.directive('scrollNav', function ($window) {
return function(scope, element, attrs) {
angular.element($window).bind("scroll", function() {
if (this.pageYOffset >= 50) {
scope.scrollDown = true;
} else {
scope.scrollDown = false;
}
scope.$apply();
});
};
});
This will do the job nicely, animated and cool way.

With a Microsoft compiler[1], static variables that are not int
-like can also be defined in a header file, but outside of the class declaration, using the Microsoft specific __declspec(selectany)
.
class A
{
static B b;
}
__declspec(selectany) A::b;
Note that I'm not saying this is good, I just say it can be done.
[1] These days, more compilers than MSC support __declspec(selectany)
- at least gcc and clang. Maybe even more.
If you're like me and tried a few of these methods and are stuck at the point that you have the control in the toolbox and can draw it on the form but it disappears from the form and puts it down in the components, then simply edit the designer and add the following in the appropriate area of InitializeComponent() to make it visible:
this.Controls.Add(this.reportViewer1);
or
[ContainerControl].Controls.Add(this.reportViewer1);
You'll also need to make adjustments to the location and size manually after you've added the control.
Not a great answer for sure, but if you're stuck and just need to get work done for now until you have more time to figure it out, it should help.

You have not given us your representation of a polygon. So I am choosing (more like suggesting) one for you :)
Represent each polygon as one big convex polygon, and a list of smaller convex polygons which need to be 'subtracted' from that big convex polygon.
Now given two polygons in that representation, you can compute the intersection as:
Compute intersection of the big convex polygons to form the big polygon of the intersection. Then 'subtract' the intersections of all the smaller ones of both to get a list of subracted polygons.
You get a new polygon following the same representation.
Since convex polygon intersection is easy, this intersection finding should be easy too.
This seems like it should work, but I haven't given it more deeper thought as regards to correctness/time/space complexity.
You can try this:
$c = array_map(function () {
return array_sum(func_get_args());
},$a, $b);
and finally:
print_r($c);
You can use CSS:
p.capitalize {text-transform:capitalize;}

There are good resources out there if you know what to search for. Try "Contract First" and WCF. or "WSDL First" and WCF.
Here is a selection:
The below regex will help to validate hh:mm format
^([0-1][0-9]|2[0-3]):[0-5][0-9]$
Yes:
df -k .
for the current directory.
df -k /some/dir
if you want to check a specific directory.
You might also want to check out the stat(1)

L = [np.random.randn(5,4,2,5,1,2) for i in range(10)]
# Stack them using axis=0.
M = np.stack(L)
M.shape # == (10,5,4,2,5,1,2)
np.all(M == L) # == True
M = np.stack(L, axis=1)
M.shape # == (5,10,4,2,5,1,2)
np.all(M == L) # == False (Don't Panic)
# This are all true
np.all(M[:,0,:] == L[0]) # == True
all(np.all(M[:,i,:] == L[i]) for i in range(10)) # == True

Try changing the perspective to JavaEE and then check.
You have to use the SelectMany
extension method or its equivalent syntax in pure LINQ.

from user in model.users
where user.surname == "surname"
select new { user, model }).ToList();
The code below reads for any text files available in the directory which contains the script we are running. Then it opens every text file and stores the words of the text line into a list. After store the words we print each word line by line
import os, fnmatch
listOfFiles = os.listdir('.')
pattern = "*.txt"
store = []
for entry in listOfFiles:
if fnmatch.fnmatch(entry, pattern):
_fileName = open(entry,"r")
if _fileName.mode == "r":
content = _fileName.read()

for i in contentList:

store.append(i)
for i in store:
print(i)
Adding to Tim's answer:
#search:placeholder-shown {
// show background image, I like svg
// when using svg, do not use HEX for colour; you can use rbg/a instead
// also notice the single quotes
background-image url('data:image/svg+xml; utf8, <svg>... <g fill="grey"...</svg>')
// other background props
}
#search:not(:placeholder-shown) { background-image: none;}
You must have the definition of class B
before you use the class. How else would the compiler otherwise know that there exists such a function as B::add
?
Either define class B
before class A
, or move the body of A::doSomething
to after class B
have been defined, like
class B;
class A
{
B* b;
void doSomething();
};
class B
{
A* a;
void add() {}
};
void A::doSomething()
{
b->add();
}

Both do the same on all browsers, AFAIK. Checked on Chrome and Firefox, both append display:none

The best and most intuitive way is to use serialEvent()

I've built a small library a while back that handles message reception, but never had time to opensource it. This library receives \n terminated lines that represent a command and arbitrary payload, space-separated. You can tweak it to use your own protocol easily.
First of all, a library, SerialReciever.h:
#ifndef __SERIAL_RECEIVER_H__
#define __SERIAL_RECEIVER_H__
class IncomingCommand {
private:
static boolean hasPayload;
public:
static String command;
static String payload;
static boolean isReady;
static void reset() {
isReady = false;
hasPayload = false;
command = "";
payload = "";
}
static boolean append(char c) {
if (c == '\n') {
isReady = true;
return true;
}
if (c == ' ' && !hasPayload) {
hasPayload = true;
return false;
}
if (hasPayload)
payload += c;
else
command += c;
return false;
}
};
boolean IncomingCommand::isReady = false;
boolean IncomingCommand::hasPayload = false;
String IncomingCommand::command = false;
String IncomingCommand::payload = false;
#endif // #ifndef __SERIAL_RECEIVER_H__
To use it, in your project do this:
#include <SerialReceiver.h>
void setup() {
Serial.begin(115200);
IncomingCommand::reset();
}
void serialEvent() {
while (Serial.available()) {
char inChar = (char)Serial.read();
if (IncomingCommand::append(inChar))
return;
}
}
To use the received commands:
void loop() {
if (!IncomingCommand::isReady) {
delay(10);
return;
}
executeCommand(IncomingCommand::command, IncomingCommand::payload); // I use registry pattern to handle commands, but you are free to do whatever suits your project better.
IncomingCommand::reset();
The MultiCell
is used for print text with multiple lines. It has the same atributes of Cell
except for ln
and link
.
$pdf->MultiCell( 200, 40, $reportSubtitle, 1);
What multiCell does is to spread the given text into multiple cells, this means that the second parameter defines the height of each line (individual cell) and not the height of all cells (collectively).
MultiCell(float w, float h, string txt [, mixed border [, string align [, boolean fill]]])

I changed scrollable div to be with absolute position, and everything works for me
div.sidebar {

top: 30px;
padding: 20px;
bottom: 30%;
}

In my case I was using different port. Default is 5432. I was using 5433. This worked for me:
$ psql -f update_table.sql -d db_name -U db_user_name -h 127.0.0.1 -p 5433
Quoting from wikipedia:
A pointer references a location in memory, and obtaining the value at the location a pointer refers to is known as dereferencing the pointer.
Dereferencing is done by applying the unary *
operator on the pointer.
int x = 5;
int * p; // pointer declaration
p = &x; // pointer assignment
*p = 7; // pointer dereferencing, example 1
int y = *p; // pointer dereferencing, example 2
"Dereferencing a NULL pointer" means performing *p
when the p
is NULL
If you are pressed by performance issuses, have a look at GMPY
It is a memory protection concept. In this compiler creates extra copy to modify data in child and this updated data not reflect in parents data.
Yes, std::vector<T>::push_back()
creates a copy of the argument and stores it in the vector. If you want to store pointers to objects in your vector, create a std::vector<whatever*>
instead of std::vector<whatever>
.
However, you need to make sure that the objects referenced by the pointers remain valid while the vector holds a reference to them (smart pointers utilizing the RAII idiom solve the problem).
Actually, there appears to now be a simple way. The following code works in TypeScript 1.5:
function sayName({ first, last = 'Smith' }: {first: string; last?: string }): void {
const name = first + ' ' + last;
console.log(name);
}
sayName({ first: 'Bob' });
The trick is to first put in brackets what keys you want to pick from the argument object, with key=value
for any defaults. Follow that with the :
and a type declaration.
This is a little different than what you were trying to do, because instead of having an intact params
object, you have instead have dereferenced variables.
If you want to make it optional to pass anything to the function, add a ?
for all keys in the type, and add a default of ={}
after the type declaration:
function sayName({first='Bob',last='Smith'}: {first?: string; last?: string}={}){
var name = first + " " + last;
alert(name);
}
sayName();

There does seem to be a lack of information on the subject. I recently implemented this system, and I found a really good GDC Powerpoint that explained the details that are often left behind quite well. That document is here: Theory and Practice of Game Object Component Architecture
In addition to that Powerpoint, there are some good resources and various blogs. PurplePwny has a good discussion and links to some other resources. Ugly Baby Studios has a bit of a discussion around the idea of how components interact with each other. Good luck!

for index in a:
This will cause index
to take on the values of the elements of a
, so using them as indices is not what you want. In Python, we iterate over a container by actually iterating over it.
"But wait", you say, "For each of those elements of a
, I need to work with the corresponding element of m
. How am I supposed to do that without indices?"
Simple. We transform a
and m
into a list of pairs (element from a, element from m), and iterate over the pairs. Which is easy to do - just use the built-in library function zip
, as follows:
for a_element, m_element in zip(a, m):
s[a_element] = m_element
To make it work the way you were trying to do it, you would have to get a list of indices to iterate over. This is doable: we can use range(len(a))
for example. But don't do that! That's not how we do things in Python. Actually directly iterating over what you want to iterate over is a beautiful, mind-liberating idea.
what about operator.itemgetter
Not really relevant here. The purpose of operator.itemgetter
is to turn the act of indexing into something, into a function-like thing (what we call "a callable"), so that it can be used as a callback (for example, a 'key' for sorting or min/max operations). If we used it here, we'd have to re-call it every time through the loop to create a new itemgetter, just so that we could immediately use it once and throw it away. In context, that's just busy-work.
Check if there is any zombie process using "top" command.
docker ps | grep <<container name>>
Get the container id.
ps -ef | grep <<container id>>
ps -ef|grep defunct | grep java
And kill the container by Parent PID .
>>> locals()['foo']
{}
>>> globals()['foo']
{}
If you wanted to write your own function, it could be done such that you could check for a variable defined in locals then check globals. If nothing is found you could compare on id() to see if the variable points to the same location in memory.
If your variable is in a class, you could use className.dict.keys() or vars(self) to see if your variable has been defined.
Yes, according to RFC 3696 apostrophes are valid as long as they come before the @ symbol.
You may already find your answer because it was some time ago you asked. But I tried to do something similar when coding ror. I wanted to run "rails server" in a new cmd window so I don't have to open a new cmd and then find my path again.
What I found out was to use the K switch like this:
start cmd /k echo Hello, World!
start before "cmd" will open the application in a new window and "/K" will execute "echo Hello, World!" after the new cmd is up.
You can also use the /C switch for something similar.
start cmd /C pause
This will then execute "pause" but close the window when the command is done. In this case after you pressed a button. I found this useful for "rails server", then when I shutdown my dev server I don't have to close the window after.
Use the following in your batch file:
start cmd.exe /c "more-batch-commands-here"
or
start cmd.exe /k "more-batch-commands-here"
/c Carries out the command specified by string and then terminates
/k Carries out the command specified by string but remains
The /c
and /k
options controls what happens once your command finishes running. With /c
the terminal window will close automatically, leaving your desktop clean. With /k
the terminal window will remain open. It's a good option if you want to run more commands manually afterwards.
Consult the cmd.exe documentation using cmd /?
for more details.
The proper formatting of the command string becomes more complicated when using arguments with spaces. See the examples below. Note the nested double quotes in some examples.
Run a program and pass a filename parameter:
CMD /c write.exe c:\docs\sample.txt
Run a program and pass a filename which contains whitespace:
CMD /c write.exe "c:\sample documents\sample.txt"
Spaces in program path:
CMD /c ""c:\Program Files\Microsoft Office\Office\Winword.exe""
Spaces in program path + parameters:
CMD /c ""c:\Program Files\demo.cmd"" Parameter1 Param2
CMD /k ""c:\batch files\demo.cmd" "Parameter 1 with space" "Parameter2 with space""
Launch demo1 and demo2:
CMD /c ""c:\Program Files\demo1.cmd" & "c:\Program Files\demo2.cmd""

In my case for EF 6+, instead of using this in the Immediate Window to find the query string:
var sql = ((System.Data.Entity.Core.Objects.ObjectQuery)query).ToTraceString();
I ended up having to use this to get the generated SQL command:
var sql = ((System.Data.Entity.Infrastructure.DbQuery<<>f__AnonymousType3<string,string,string,short,string>>)query).ToString();
Of course your anonymous type signature might be different.
HTH.
To index on any criteria, you can so something like the following:
In [1]: from numpy import *
In [2]: x = arange(125).reshape((5,5,5))
In [3]: y = indices(x.shape)
In [4]: locs = y[:,x >= 120] # put whatever you want in place of x >= 120
In [5]: pts = hsplit(locs, len(locs[0]))
In [6]: for pt in pts:
.....: print(', '.join(str(p[0]) for p in pt))
4, 4, 0
4, 4, 1
4, 4, 2
4, 4, 3
4, 4, 4
And here's a quick function to do what list.index() does, except doesn't raise an exception if it's not found. Beware -- this is probably very slow on large arrays. You can probably monkey patch this on to arrays if you'd rather use it as a method.
def ndindex(ndarray, item):
if len(ndarray.shape) == 1:
try:
return [ndarray.tolist().index(item)]
except:
pass
else:
for i, subarray in enumerate(ndarray):
try:
return [i] + ndindex(subarray, item)
except:
pass
In [1]: ndindex(x, 103)
Out[1]: [4, 0, 3]
As pointed in Vlad's answer, you are running out of free color slots. One way to get around that would be to cache the colors: whenever you try a RGB combination, the routine should first check if the combination is in the cache; if it is in the cache, then it should use that one instead of creating a new one from scratch; new colors would then only be created if they're not yet in cache.
Here's the implementation I use; it uses XSSF plus Guava's LoadingCache and is geared towards generationg XSSF colors from CSS rgb(r, g, b)
declarations, but it should be relatively trivial to adapt it to HSSF:
private final LoadingCache<String, XSSFColor> colorsFromCSS = CacheBuilder.newBuilder()
.build(new CacheLoader<String, XSSFColor>() {
private final Pattern RGB = Pattern.compile("rgb\\(\\s*(\\d+)\\s*, \\s*(\\d+)\\s*,\\s*(\\d+)\\s*\\)");
@Override
public XSSFColor load(String style) throws Exception {
Matcher mat = RGB.matcher(style);
if (!mat.find()) {
throw new IllegalStateException("Couldn't read CSS color: " + style);
}
return new XSSFColor(new java.awt.Color(
Integer.parseInt(mat.group(1)),
Integer.parseInt(mat.group(2)),
Integer.parseInt(mat.group(3))));
}
});
Perhaps someone else could post a HSSF equivalent? ;)
You need to find the selected option:
$(this).find(':selected').data('id')
or
$(this).find(':selected').attr('data-id')
although the first method is preferred.
WordPad will open any text file no matter the size. However, it has limited capabilities as compared to a text editor.
You could use this CMD in your Dockerfile
:
CMD exec /bin/bash -c "trap : TERM INT; sleep infinity & wait"
This will keep your container alive until it is told to stop. Using trap and wait will make your container react immediately to a stop request. Without trap/wait stopping will take a few seconds.
For busybox based images (used in alpine based images) sleep does not know about the infinity argument. This workaround gives you the same immediate response to a docker stop
like in the above example:
CMD exec /bin/sh -c "trap : TERM INT; sleep 9999999999d & wait"
This is an option:
dbContext.Entry(entity).State = EntityState.Detached;
it work for me
Use these following commands, this will solve the error:
sudo apt-get install postgresql
then fire:
sudo apt-get install python-psycopg2
and last:
sudo apt-get install libpq-dev
You could also do
var x = $('#element').height(); // or any changing value
$('selector').css({'top' : x + 'px'});
OR
You can use directly
$('#element').css( "height" )
The difference between .css( "height" )
and .height()
is that the latter returns a unit-less pixel value (for example, 400
) while the former returns a value with units intact (for example, 400px
). The .height() method is recommended when an element's height needs to be used in a mathematical calculation. jquery doc
:-) Once I found myself in the same situation, there was no jQuery plugin matching my requeriments, so I spend some time developing my own one: colResizable
colResizable is a free jQuery plugin to resize table columns dragging them manually. It is compatible with both mouse and touch devices and has some nice features such as layout persistence after page refresh or postback. It works with both percentage and pixel-based table layouts.
It is tiny in size (colResizable 1.0 is only 2kb) and it is fully compatible with all major browsers (IE7+, Firefox, Chrome and Opera).
colResizable was developed since no other similar plugin with the below listed features was found:
colResizable is the most polished plugin to resize table columns out there. It has plenty of customization possibilities and it is also compatible with touch devices. But probably the most interesting feature which is making colResizable the greatest choice is that it is compatible with both pixel-based and fluid percentage table layouts. But, what does it mean?
If the width of a table is set to, lets say 90%, and the column widths are modified using colResizable, when the browser is resized columns widths are resized proportionally. While other plugins does behave odd, colResizable does its job just as expected.
colResizable is also compatible with table max-width attribute: if the sum of all columns exceed the table's max-width, they are automatically fixed and updated.
Another great advantage compared with other plugins is that it is compatible with page refresh, postbacks and even partial postbacks if the table is located inside of an updatePanel. It is compatible with all major browsers (IE7+, Firefox, Chrome and Opera), while other plugins fail with old IE versions.
$("#sample").colResizable({
liveDrag:true
});

Be sure to return it to default when you are done
Application.AutomationSecurity = msoAutomationSecurityLow
A reminder that the .SaveAs
function contains all optional arguments.I recommend removing CreatBackup:= False
as it is not necessary.
The most interesting way I think is to create an object of the workbook and access the .SaveAs
property that way. I have not tested it but you are never using Workbooks.Open
rendering Application.AutomationSecurity
inapplicable. Possibly saving resources and time as well.
That said I was able to execute the following without any notifications on Excel 2013 windows 10.

You could use my JavaScript hash table implementation, jshashtable. It allows any object to be used as a key, not just strings.
I have used the following before:
var my_form = $('#form-id');
var data = {};
$('input:not([type=checkbox]), input[type=checkbox]:selected, select, textarea', my_form).each(
function() {
var name = $(this).attr('name');
var val = $(this).val();
if (!data.hasOwnProperty(name)) {
data[name] = new Array;
}
data[name].push(val);
}
);
This is just written from memory, so might contain mistakes, but this should make an object called data
that contains the values for all your inputs.
Note that you have to deal with checkboxes in a special way, to avoid getting the values of unchecked checkboxes. The same is probably true of radio inputs.
Also note using arrays for storing the values, as for one input name, you might have values from several inputs (checkboxes in particular).
If your keys are dynamic I would suggest deserializing directly into a DataTable:
class SampleData
{
[JsonProperty(PropertyName = "items")]
public System.Data.DataTable Items { get; set; }
}
public void DerializeTable()
{
const string json = @"{items:["
+ @"{""Name"":""AAA"",""Age"":""22"",""Job"":""PPP""},"
+ @"{""Name"":""BBB"",""Age"":""25"",""Job"":""QQQ""},"
+ @"{""Name"":""CCC"",""Age"":""38"",""Job"":""RRR""}]}";
var sampleData = JsonConvert.DeserializeObject<SampleData>(json);
var table = sampleData.Items;
// write tab delimited table without knowing column names
var line = string.Empty;
foreach (DataColumn column in table.Columns)
line += column.ColumnName + "\t";
Console.WriteLine(line);
foreach (DataRow row in table.Rows)
{
line = string.Empty;
foreach (DataColumn column in table.Columns)
line += row[column] + "\t";
Console.WriteLine(line);
}
// Name Age Job
// AAA 22 PPP
// BBB 25 QQQ
// CCC 38 RRR
}
You can determine the DataTable column names and types dynamically once deserialized.
If you already have material-icons working in your web project, just need to update your reference in the html file and the used class for icons:
html reference:
Before
<link href="https://fonts.googleapis.com/icon?family=Material+Icons" rel="stylesheet" />
After
<link href="https://fonts.googleapis.com/css?family=Material+Icons|Material+Icons+Outlined|Material+Icons+Two+Tone|Material+Icons+Round|Material+Icons+Sharp"
rel="stylesheet" />
material icons class:
After that just check wich className are you using:
Before:
<i className="material-icons">weekend</i>
After:
<i className="material-icons-outlined">weekend</i>
that works for me... Pura vida!

Simply we can do this:

For those looking for an example of how to pass the OAuth2 authorization (access token) in the header (as opposed to using a request or body parameter), here is how it's done:
Authorization: Bearer 0b79bab50daca910b000d4f1a2b675d604257e42
This may not be as slick as a one-liner, but I use it to perform date manipulation mainly for reports:
DECLARE @Date datetime
SET @Date = GETDATE()
-- Set all time components to zero
SET @Date = DATEADD(ms, -DATEPART(ms, @Date), @Date) -- milliseconds = 0
SET @Date = DATEADD(ss, -DATEPART(ss, @Date), @Date) -- seconds = 0
SET @Date = DATEADD(mi, -DATEPART(mi, @Date), @Date) -- minutes = 0
SET @Date = DATEADD(hh, -DATEPART(hh, @Date), @Date) -- hours = 0
-- Extra manipulation for month and year
SET @Date = DATEADD(dd, -DATEPART(dd, @Date) + 1, @Date) -- day = 1
SET @Date = DATEADD(mm, -DATEPART(mm, @Date) + 1, @Date) -- month = 1
I use this to get hourly, daily, monthly, and yearly dates used for reporting and performance indicators, etc.
It's not necessary to use nested form groups and a custom ErrorStateMatcher for confirm password validation. These steps were added to facilitate coordination between the password fields, but you can do that without all the overhead.
Here is an example:
this.registrationForm = this.fb.group({
username: ['', Validators.required],
email: ['', [Validators.required, Validators.email]],
password1: ['', [Validators.required, (control) => this.validatePasswords(control, 'password1') ] ],
password2: ['', [Validators.required, (control) => this.validatePasswords(control, 'password2') ] ]
});
Note that we are passing additional context to the validatePasswords method (whether the source is password1 or password2).
validatePasswords(control: AbstractControl, name: string) {
if (this.registrationForm === undefined || this.password1.value === '' || this.password2.value === '') {
return null;
} else if (this.password1.value === this.password2.value) {
if (name === 'password1' && this.password2.hasError('passwordMismatch')) {
this.password1.setErrors(null);
this.password2.updateValueAndValidity();
} else if (name === 'password2' && this.password1.hasError('passwordMismatch')) {
this.password2.setErrors(null);
this.password1.updateValueAndValidity();
}
return null;
} else {
return {'passwordMismatch': { value: 'The provided passwords do not match'}};
}
Note here that when the passwords match, we coordinate with the other password field to have its validation updated. This will clear any stale password mismatch errors.
And for completeness sake, here are the getters that define this.password1
and this.password2
.
get password1(): AbstractControl {
return this.registrationForm.get('password1');
}
get password2(): AbstractControl {
return this.registrationForm.get('password2');
}

Use empty
(it checks both nullness and emptiness) and group the nested ternary expression by parentheses (EL is in certain implementations/versions namely somewhat problematic with nested ternary expressions). Thus, so:
styleClass="#{empty obj.validationErrorMap ? ' ' :
(obj.validationErrorMap.contains('key') ? 'highlight_field' : 'highlight_row')}"
If still in vain (I would then check JBoss EL configs), use the "normal" EL approach:
styleClass="#{empty obj.validationErrorMap ? ' ' :
(obj.validationErrorMap['key'] ne null ? 'highlight_field' : 'highlight_row')}"
Update: as per the comments, the Map
turns out to actually be a List
(please work on your naming conventions). To check if a List
contains an item the "normal" EL way, use JSTL fn:contains
(although not explicitly documented, it works for List
as well).
styleClass="#{empty obj.validationErrorMap ? ' ' :
(fn:contains(obj.validationErrorMap, 'key') ? 'highlight_field' : 'highlight_row')}"
I have tried almost all the answers and some of them almost worked for me but none of these answers work perfectly. So here is my solution. For this solution, you will need to add onclick
attribute in the HTML body tag. So if you can not modify the HTML file then this solution won't work for you.
Step 1: add onclick
attribute in the HTML body tag like this:
<body onclick="ok.performClick(this.value);">
<h1>This is heading 1</h1>
<p>This is para 1</p>
</body>
Step 2: implement addJavascriptInterface
in your app to handle click listener:
webView.addJavascriptInterface(new Object() {
@JavascriptInterface
public void performClick(String string) {
handler.sendEmptyMessageDelayed(CLICK_ON_WEBVIEW, 0);
}
}, "ok");
Step 3: We can not perform any action on main thread from performClick
method so need to add Handler
class:
private final Handler handler = new Handler(this); // class-level variable
private static final int CLICK_ON_WEBVIEW = 1; // class-level variable
implement Handler.Callback
to your class and the override handleMessage
@Override
public boolean handleMessage(Message message) {
if (message.what == CLICK_ON_WEBVIEW) {
Toast.makeText(getActivity(), "WebView clicked", Toast.LENGTH_SHORT).show();
return true;
}
return false;
}
I think list comprehension is one of the cleanest ways that doesn't need any additional imports:
>>> d={"foo": 1, "bar": 2, "baz": 3}
>>> a = [d.get(k) for k in ["foo", "bar", "baz"]]
>>> a
[1, 2, 3]
Of if you want the values as individual variables then use multiple-assignment:
>>> a,b,c = [d.get(k) for k in ["foo", "bar", "baz"]]
>>> a,b,c
(1, 2, 3)

There are many questions about REST auth patterns here on SO. These are the most relevant for your question:
Basically you need to choose between using API keys (least secure as the key may be discovered by an unauthorized user), an app key and token combo (medium), or a full OAuth implementation (most secure).
Here is the example:
document.getElementsByTagName("html").foo="bar"
Here is another example how to set custom attributes into body tag element:
document.getElementsByTagName('body')[0].dataset.attr1 = "foo";
document.getElementsByTagName('body')[0].dataset.attr2 = "bar";
Then read the attribute by:
attr1 = document.getElementsByTagName('body')[0].dataset.attr1
attr2 = document.getElementsByTagName('body')[0].dataset.attr2
You can test above code in Console in DevTools, e.g.
You are single quoting your SQL statement which is making the variables text instead of variables.
$sql = "SELECT *
FROM $usertable
WHERE PartNumber = $partid";
You can use strtok()
char string[]= "abc/qwe/jkh";
char *array[10];
int i=0;
array[i] = strtok(string,"/");
while(array[i]!=NULL)
{
array[++i] = strtok(NULL,"/");
}
Use REN
Command
Ren
is for rename
ren ( where the file is located ) ( the new name )
example
ren C:\Users\&username%\Desktop\aaa.txt bbb.txt
it will change aaa.txt to bbb.txt
Your code will be :
ren (file located)AAA_a001.jpg a001.AAA.jpg
ren (file located)BBB_a002.jpg a002.BBB.jpg
ren (file located)CCC_a003.jpg a003.CCC.jpg
and so on
IT WILL NOT WORK IF THERE IS SPACES!
Hope it helps :D
This one worked for me
getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_ADJUST_NOTHING);
I could do this with a custom attribute as follows.
[AuthorizeUser(AccessLevel = "Create")]
public ActionResult CreateNewInvoice()
{
//...
return View();
}
Custom Attribute class as follows.
public class AuthorizeUserAttribute : AuthorizeAttribute
{
// Custom property
public string AccessLevel { get; set; }
protected override bool AuthorizeCore(HttpContextBase httpContext)
{
var isAuthorized = base.AuthorizeCore(httpContext);
if (!isAuthorized)
{
return false;
}
string privilegeLevels = string.Join("", GetUserRights(httpContext.User.Identity.Name.ToString())); // Call another method to get rights of the user from DB
return privilegeLevels.Contains(this.AccessLevel);
}
}
You can redirect an unauthorised user in your custom AuthorisationAttribute
by overriding the HandleUnauthorizedRequest
method:
protected override void HandleUnauthorizedRequest(AuthorizationContext filterContext)
{
filterContext.Result = new RedirectToRouteResult(
new RouteValueDictionary(
new
{
controller = "Error",
action = "Unauthorised"
})
);
}

if (!$("#myTextArea").val()) {
// textarea is empty
}
You can also use $.trim
to make sure the element doesn't contain only white-space:
if (!$.trim($("#myTextArea").val())) {
// textarea is empty or contains only white-space
}
Up until jQuery 1.11.1, you could use the following URLs to get the latest version of jQuery:
For example:
<script src="https://code.jquery.com/jquery-latest.min.js"></script>
However, since jQuery 1.11.1, both jQuery and Google stopped updating these URL's; they will forever be fixed at 1.11.1. There is no supported alternative URL to use. For an explanation of why this is the case, see this blog post; Don't use jquery-latest.js.
Both hosts support https
as well as http
, so change the protocol as you see fit (or use a protocol relative URI)

This is an old post but...
You can reference the working directory (the folder the .html file is located in) with ./
, and the directory above that with ../
Example directory structure:
/html/public/
- index.html
- script2.js
- js/
- script.js
To load script.js from inside index.html:
<script type="text/javascript" src="./js/script.js">
This goes to the current working directory (location of index.html) and then to the js folder, and then finds the script.
You could also specify ../
to go one directory above the working directory, to load things from there. But that is unusual.
Some limited flexibility is available if your using the Afterglow Theme.

Typographically, the correct glyph to use in sentence punctuation is the quote mark, both single (including for apostrophes) and double quotes. The straight-looking mark that we often see on the web is called a prime, which also comes in single and double varieties and has limited uses, mostly for measurements.
This article explains how to use them correctly.
The question is quite old so I feel like I need to give a more up to date response to this question.

Specify the ax
argument to matplotlib.pyplot.colorbar()
, e.g.
import numpy as np
import matplotlib.pyplot as plt
fig, ax = plt.subplots(2, 2)
for i in range(2):
for j in range(2):
data = np.array([[i, j], [i+0.5, j+0.5]])
im = ax[i, j].imshow(data)
plt.colorbar(im, ax=ax[i, j])
plt.show()
DateFormat formatter = new SimpleDateFormat("dd/MM/yyyy");
formatter.setLenient(false);
try {
Date date= formatter.parse("02/03/2010");
} catch (ParseException e) {
//If input date is in different format or invalid.
}
formatter.setLenient(false) will enforce strict matching.
If you are using Joda-Time -
private boolean isValidDate(String dateOfBirth) {
boolean valid = true;
try {
DateTimeFormatter formatter = DateTimeFormat.forPattern("dd/MM/yyyy");
DateTime dob = formatter.parseDateTime(dateOfBirth);
} catch (Exception e) {
valid = false;
}
return valid;
}
You won't get real HTML rendering to <canvas>
per se currently, because canvas context does not have functions to render HTML elements.
There are some emulations:
html2canvas project http://html2canvas.hertzen.com/index.html (basically a HTML renderer attempt built on Javascript + canvas)
HTML to SVG to <canvas>
might be possible depending on your use case:
https://github.com/miohtama/Krusovice/blob/master/src/tools/html2svg2canvas.js
Also if you are using Firefox you can hack some extended permissions and then render a DOM window to <canvas>
This is the method I used, with a server-side include, e.g. <!--#include file="emailObfuscator.include" -->
where emailObfuscator.include
contains the following:
<!-- // http://lists.evolt.org/archive/Week-of-Mon-20040202/154813.html -->
<script type="text/javascript">
function gen_mail_to_link(lhs,rhs,subject) {
document.write("<a href=\"mailto");
document.write(":" + lhs + "@");
document.write(rhs + "?subject=" + subject + "\">" + lhs + "@" + rhs + "<\/a>");
}
</script>
To include an address, I use JavaScript:
<script type="text/javascript">
gen_mail_to_link('john.doe','example.com','Feedback about your site...');
</script>
<noscript>
<em>Email address protected by JavaScript. Activate JavaScript to see the email.</em>
</noscript>
Because I have been getting email via Gmail since 2005, spam is pretty much a non-issue. So, I can't speak of how effective this method is. You might want to read this study (although it's old) that produced this graph:
In my case, I was impatient and ended up misinterpreting the log.
In fact, the real problem was the communication between nginx and uwsgi, and not between the browser and nginx. If I had loaded the site in my browser and had waited long enough I would have gotten a "504 - Bad Gateway". But it took so long, that I kept trying stuff, and then refresh in the browser. So I never waited long enough to see the 504 error. When refreshing in the browser, that is when the previous request is closed, and Nginx writes that in the log as 499.
Here I will assume that the reader knows as little as I did when I started playing around.
My setup was a reverse proxy, the nginx server, and an application server, the uWSGI server behind it. All requests from the client would go to the nginx server, then forwarded to the uWSGI server, and then response was sent the same way back. I think this is how everyone uses nginx/uwsgi and are supposed to use it.
My nginx worked as it should, but something was wrong with the uwsgi server. There are two ways (maybe more) in which the uwsgi server can fail to respond to the nginx server.
1) uWSGI says, "I'm processing, just wait and you will soon get a response". nginx has a certain period of time, that it is willing to wait, fx 20 seconds. After that, it will respond to the client, with a 504 error.
2) uWSGI is dead, or uWSGi dies while nginx is waiting for it. nginx sees that right away and in that case, it returns a 499 error.
I was testing my setup by making requests in the client (browser). In the browser nothing happened, it just kept hanging. After maybe 10 seconds (less than the timeout) I concluded that something was not right (which was true), and closed the uWSGI server from the command line. Then I would go to the uWSGI settings, try something new, and then restart the uWSGI server. The moment I closed the uWSGI server, the nginx server would return a 499 error.
So I kept debugging with the 499 erroe, which means googling for the 499 error. But if I had waited long enough, I would have gotten the 504 error. If I had gotten the 504 error, I would have been able to understand the problem better, and then be able to debug.
So the conclusion is, that the problem was with uWGSI, which kept hanging ("Wait a little longer, just a little longer, then I will have an answer for you...").
How I fixed that problem, I don't remember. I guess it could be caused by a lot of things.
I wouldn't recommend you to extend native prototypes. Instead, you can use a library like new-list; https://github.com/azer/new-list
It creates a native JavaScript array and lets you subscribe to any change. It batches the updates and gives you the final diff;
List = require('new-list')
todo = List('Buy milk', 'Take shower')
todo.pop()
todo.push('Cook Dinner')
todo.splice(0, 1, 'Buy Milk And Bread')
todo.subscribe(function(update){ // or todo.subscribe.once
update.add
// => { 0: 'Buy Milk And Bread', 1: 'Cook Dinner' }
update.remove
// => [0, 1]
})
