I was also trying to achieve this. From above codes, what I understood was that you can call getch() function multiple times in order to get both bytes getting from the function. So the ord() function is not necessary if you are just looking to use with byte objects.
while True :
if m.kbhit() :
k = m.getch()
if b'\r' == k :
break
elif k == b'\x08'or k == b'\x1b':
# b'\x08' => BACKSPACE
# b'\x1b' => ESC
pass
elif k == b'\xe0' or k == b'\x00':
k = m.getch()
if k in [b'H',b'M',b'K',b'P',b'S',b'\x08']:
# b'H' => UP ARROW
# b'M' => RIGHT ARROW
# b'K' => LEFT ARROW
# b'P' => DOWN ARROW
# b'S' => DELETE
pass
else:
print(k.decode(),end='')
else:
print(k.decode(),end='')
This code will work print any key until enter key is pressed in CMD or IDE (I was using VS CODE) You can customize inside the if for specific keys if needed
I had a similar issue when calling the WPF window out of WinForms.
var wpfwindow = new ScreenBoardWPF.IzbiraProjekti();
ElementHost.EnableModelessKeyboardInterop(wpfwindow);
wpfwindow.Show();
However, showing window as a dialog, it worked
var wpfwindow = new ScreenBoardWPF.IzbiraProjekti();
ElementHost.EnableModelessKeyboardInterop(wpfwindow);
wpfwindow.ShowDialog();
Hope this helps.
You should use tabIndex attribute to be able to listen onKeyDown
event on a div in React. Setting tabIndex="0"
should fire your handler.
I like to use this snippet, its very useful for writing game input scripts
var keyMap = [];
window.addEventListener('keydown', (e)=>{
if(!keyMap.includes(e.keyCode)){
keyMap.push(e.keyCode);
}
})
window.addEventListener('keyup', (e)=>{
if(keyMap.includes(e.keyCode)){
keyMap.splice(keyMap.indexOf(e.keyCode), 1);
}
})
function key(x){
return (keyMap.includes(x));
}
function checkGameKeys(){
if(key(32)){
// Space Key
}
if(key(37)){
// Left Arrow Key
}
if(key(39)){
// Right Arrow Key
}
if(key(38)){
// Up Arrow Key
}
if(key(40)){
// Down Arrow Key
}
if(key(65)){
// A Key
}
if(key(68)){
// D Key
}
if(key(87)){
// W Key
}
if(key(83)){
// S Key
}
}

If you add e.SuppressKeyPress = true;
as shown in the answer in this link you will suppress the annoying ding sound that occurs.
I am a little late to the party but here is my part
$(document).on('keydown', function ( e ) {
// You may replace `c` with whatever key you want
if ((e.metaKey || e.ctrlKey) && ( String.fromCharCode(e.which).toLowerCase() === 'c') ) {
console.log( "You pressed CTRL + C" );
}
});
There is a package that can do this which creates a UI within the django admin site: https://github.com/RealGeeks/django-modelclone
pip install django-modelclone
Add "modelclone" to INSTALLED_APPS and import it within admin.py.
Then, whenever you want to make a model clonable, you just replace "admin.ModelAdmin" in the given admin model class "modelclone.ClonableModelAdmin". This results in a "Duplicate" button appearing within the instance details page for that given model.
A simpler way
git add . -A
git commit -m "Deleted some files..."
git push origin master
-A Update the index not only where the working tree has a file matching but also where the index already has an entry. This adds, modifies, and removes index entries to match the working tree. Taken from (http://git-scm.com/docs/git-add)
I might be a little late to the party but any of these two might work for you:
String str;
String path = "C:/Users/...the path..../iin.txt"; // you can input also..i created this way :P
BufferedReader br = new BufferedReader(new InputStreamReader(System.in));
PrintWriter pw = new PrintWriter(new FileWriter(path, true));
try
{
while(true)
{
System.out.println("Enter the text : ");
str = br.readLine();
if(str.equalsIgnoreCase("exit"))
break;
else
pw.println(str);
}
}
catch (Exception e)
{
//oh noes!
}
finally
{
pw.close();
}
this will do what you intend for..
In my case, the problem was that I had different dimensions compared to normal one. I had 48x48 px
whereas it was expecting 32x32 px
and my extension was png so I had to change it to ico
ln -s . someProject
If you have someDirectory/someProjectDir and two files, file1.py and file2.py, and file1.py tries to import with this line
from someProjectDir import file2
It won't work, even if you have designated the someProjectDir as a source directory, and even if it shows in preferences, project, project structure menu as a content root. The only way it will work is by linking the project as show above (unix command, works in mac, not sure of use or syntax for Windows). There seems some mechanism where Pycharm does this automatically either in checkout from version control or adding as context root, since the soft link was created by Pycharm in a dependent project. Hence, just copying the same, although the weird replication of directory is annoying and necessity is perplexing. Also in the dependency where auto created, it doesn't show as new directory under version control. Perhaps comparison of .idea files will reveal more.
You have wrong database design and you should take a time to read something about database normalization (wikipedia / stackoverflow).
I assume your table looks somewhat like this
TABLE
================================
| group_id | user_ids | name |
--------------------------------
| 1 | 1,4,6 | group1 |
--------------------------------
| 2 | 4,5,1 | group2 |
so in your table of user groups, each row represents one group and in user_ids
column you have set of user ids assigned to that group.
Normalized version of this table would look like this
GROUP
=====================
| id | name |
---------------------
| 1 | group1 |
---------------------
| 2 | group2 |
GROUP_USER_ASSIGNMENT
======================
| group_id | user_id |
----------------------
| 1 | 1 |
----------------------
| 1 | 4 |
----------------------
| 1 | 6 |
----------------------
| 2 | 4 |
----------------------
| ...
Then you can easily select all users with assigned group, or all users in group, or all groups of user, or whatever you can think of. Also, your sql query will work:
/* Your query to select assignments */
SELECT * FROM `group_user_assignment` WHERE user_id IN (1,2,3,4);
/* Select only some users */
SELECT * FROM `group_user_assignment` t1
JOIN `group` t2 ON t2.id = t1.group_id
WHERE user_id IN (1,4);
/* Select all groups of user */
SELECT * FROM `group_user_assignment` t1
JOIN `group` t2 ON t2.id = t1.group_id
WHERE t1.`user_id` = 1;
/* Select all users of group */
SELECT * FROM `group_user_assignment` t1
JOIN `group` t2 ON t2.id = t1.group_id
WHERE t1.`group_id` = 1;
/* Count number of groups user is in */
SELECT COUNT(*) AS `groups_count` FROM `group_user_assignment` WHERE `user_id` = 1;
/* Count number of users in group */
SELECT COUNT(*) AS `users_count` FROM `group_user_assignment` WHERE `group_id` = 1;
This way it will be also easier to update database, when you would like to add new assignment, you just simply insert new row in group_user_assignment
, when you want to remove assignment you just delete row in group_user_assignment
.
In your database design, to update assignments, you would have to get your assignment set from database, process it and update and then write back to database.
Here is sqlFiddle to play with.
As already mentioned, they are the same, but I use either the one or the other depending on the language in which the corresponding framework was written.
For everything related to Objective-C, I use nil. For example:
- (BOOL)doSomethingWithObjectsInArray:(NSArray *)anArray {
if (anArray == nil) return NO;
// process elements
...
}
However, when checking validity of data models from a C-framework (like AddressBook framework and CoreFoundation), I use NULL. For example:
- (BOOL)showABUnknownPersonVCForABRecordRef:(ABRecordRef)aRecord {
if (aRecord == NULL) return NO;
// set-up the ABUnknownPersonViewController and display it on screen
..
}
This way, I have subtle clues in my code if I'm dealing with Obj-C or C based code.
I am note sure, what you are expecting. Have a look at this fiddle, this might help you.
You HTML should have the class navbar-fixed-top

If you can use CSS and are willing to use the deprecated align
attribute, a styled fieldset/legend will work:
<style type="text/css">
fieldset {
border-width: 1px 0 0 0;
}
</style>
<fieldset>
<legend align="center">First Section</legend>
Section 1 Stuff
</fieldset>
<fieldset>
<legend align="center">Second Section</legend>
Section 2 Stuff
</fieldset>
The intended purpose of a fieldset is to logically group form fields. As willoler pointed out, a text-align: center
style for will not work for legend
elements. align="center"
is deprecated HTML but it should center the text properly in all browsers.
My solution is a mix of several answers here.
I checked the build server, and Windows7/NET4.0 SDK was already installed, so I did find the path:
C:\Program Files (x86)\MSBuild\Microsoft\VisualStudio\v9.0\WebApplications\Microsoft.WebApplication.targets`
However, on this line:
<Import Project="$(MSBuildExtensionsPath)\Microsoft\VisualStudio\v9.0\WebApplications\Microsoft.WebApplication.targets" />
$(MSBuildExtensionsPath) expands to C:\Program Files\MSBuild which does not have the path.
Therefore what I did was to create a symlink, using this command:
mklink /J "C:\Program Files\MSBuild\Microsoft\VisualStudio" "C:\Program Files (x86)\MSBuild\Microsoft\VisualStudio"
This way the $(MSBuildExtensionsPath) expands to a valid path, and no changes are needed in the app itself, only in the build server (perhaps one could create the symlink every build, to make sure this step is not lost and is "documented").

I believe those who study typography would tell you that 66 characters per a line is supposed to be the most readable width for length. Even so, if you need to debug a machine remotely over an ssh session, most terminals default to 80 characters, 79 just fits, trying to work with anything wider becomes a real pain in such a case. You would also be suprised by the number of developers using vim + screen as a day to day environment.

Check out the ideas at Mu Dynamics Research Labs - Blog Archive. I found this earlier this year - I forget the exact context where I came across it - and have adapted it into this code. We can debate the merits of adding an E at the front; it is applicable to the specific problem addressed, but not part of a general solution. I stashed this away in my 'vignettes' folder - where I keep interesting scraps of code in case I want them later. I'm embarrassed to say that I didn't keep a note of where this idea came from at the time.

"e:\\directory\\-"
You can use text-align: center; line-height: 65px;
CSS
.loginBtn {
background:url(images/loginBtn-center.jpg) repeat-x;
width:175px;
height:65px;
margin:20px auto;
border-radius:10px;
-webkit-border-radius:10px;
box-shadow:0 1px 2px #5e5d5b;
text-align: center; <--------- Here
line-height: 65px; <--------- Here
}
You can use contains
(this works with an arbitrary sequence):
df.filter($"foo".contains("bar"))
like
(SQL like with SQL simple regular expression whith _
matching an arbitrary character and %
matching an arbitrary sequence):
df.filter($"foo".like("bar"))
or rlike
(like with Java regular expressions):
df.filter($"foo".rlike("bar"))
depending on your requirements. LIKE
and RLIKE
should work with SQL expressions as well.

Edit the Application Class as Follows
class FTApplication: MultiDexApplication() {
override fun attachBaseContext(base: Context?) {
super.attachBaseContext(base)
MultiDex.install(this)
}
init {
instance = this
}
val mFTActivityLifecycleCallbacks = FTActivityLifecycleCallbacks()
override fun onCreate() {
super.onCreate()
registerActivityLifecycleCallbacks(mFTActivityLifecycleCallbacks)
}
companion object {
private var instance: FTApplication? = null
fun currentActivity(): Activity? {
return instance!!.mFTActivityLifecycleCallbacks.currentActivity
}
}
}
Create the ActivityLifecycleCallbacks class
class FTActivityLifecycleCallbacks: Application.ActivityLifecycleCallbacks {
var currentActivity: Activity? = null
override fun onActivityPaused(activity: Activity?) {
currentActivity = activity
}
override fun onActivityResumed(activity: Activity?) {
currentActivity = activity

override fun onActivityStarted(activity: Activity?) {
currentActivity = activity
}
override fun onActivityDestroyed(activity: Activity?) {

override fun onActivitySaveInstanceState(activity: Activity?, outState: Bundle?) {
}
override fun onActivityStopped(activity: Activity?) {
}
override fun onActivityCreated(activity: Activity?, savedInstanceState: Bundle?) {
currentActivity = activity

Here are the instructions for Windows users on connecting to a RPi by using just an Ethernet cable and a DHCP server. There is no need for a cross over cable, as the RPi can handle it. I have a blog post that documents this with pictures here which may be easier to follow.
Downloads
Download the DHCP Server for Windows (download link is here). Unzip the zip file and open the dhcpwiz application, which will configure the DHCP server.
DHCP Server Configuration
Hit next on the first screen.
On the second screen, look for a "Local Area Connection" row and verify its IP address is 0.0.0.0
and its status is enabled
. Connect the Ethernet cable from the RPi to your laptop, and turn on the Pi. Hit refresh on this screen until the IP address changes to 169.254.*.*
. If it is anything else then you should alter your network settings for the Local Area Connection (make sure it is not a static IP/DNS). Click on this Local Area Connection row and hit next.
Check HTTP (Web Server)
. This makes it much more easy to locate the RPi's IP address. Hit Next.
Take the defaults and hit Next until you get to the Writing the INI file
screen. Check Overwrite existing file
and hit the Write INI file
button. Then hit Next.
On the final screen, check Run DHCP server immediately
and hit `Finish.
DHCP Server and Obtaining the IP Address of your Raspberry PI
This launches the actual DHCP server, using the configuration you just created in the previous wizard. Click the Continue as tray app
button, and the DHCP server will be minimized to your system tray.
Anywhere from 1 second to 5 minutes from now you will see an alert on the system tray with your laptop and your RPi's new IP address. This alert is really quick and you will probably miss it. Normally your RPi's IP is 169.254.0.2
, but it could be *.01
or even something else. It is easier to access the DHCP server's web UI at http://localhost/dhcpstatus.xml. This will list the hostname as "raspberrypi" with its IP address.
Now you can putty or remote desktop into your RPi, and configure its wireless settings or whatever you want to do.
Trouble shooting
This can be somewhat finicky. I've had my connection appear to drop and have been unable to SSH back in using the IP address. Normally, I can restart the Pi and get the IP address again. Sometimes I have to restart both the RPi and the DHCP server. Sometimes I have to do this multiple times. At one point when I wasn't getting a connection for 15 minutes, I copied all of the files in the dhcpsrv2.5.1 folder to a new folder and tried again; it immediately worked.
"^" For the begining of the line "$" for the end of it. Eg.:
var re = /^abc$/;
Would match "abc" but not "1abc" or "abc1". You can learn more at https://developer.mozilla.org/en-US/docs/Web/JavaScript/Guide/Regular_Expressions
You can do this after you validate your data.

data = myform.cleaned_data

I want to add another solution: In my case, I need to use a Enum group in a drop down button list items. So they might have space, i.e. more user friendly descriptions needed:
public enum CancelReasonsEnum
{
[Description("In rush")]
InRush,
[Description("Need more coffee")]
NeedMoreCoffee,
[Description("Call me back in 5 minutes!")]
In5Minutes
}
In a helper class (HelperMethods) I created the following method:
public static List<string> GetListOfDescription<T>() where T : struct
{
Type t = typeof(T);
return !t.IsEnum ? null : Enum.GetValues(t).Cast<Enum>().Select(x => x.GetDescription()).ToList();
}
When you call this helper you will get the list of item descriptions.
List<string> items = HelperMethods.GetListOfDescription<CancelReasonEnum>();
ADDITION: In any case, if you want to implement this method you need :GetDescription extension for enum. This is what I use.
public static string GetDescription(this Enum value)
{
Type type = value.GetType();
string name = Enum.GetName(type, value);
if (name != null)
{
FieldInfo field = type.GetField(name);
if (field != null)
{
DescriptionAttribute attr =Attribute.GetCustomAttribute(field,typeof(DescriptionAttribute)) as DescriptionAttribute;
if (attr != null)
{
return attr.Description;
}
}
}
return null;
/* how to use
MyEnum x = MyEnum.NeedMoreCoffee;
string description = x.GetDescription();
*/
}
In the first case you are declaring "int a" as a local variable(as declared inside a method) and local varible do not get default value.
But instance variable are given default value both for static and non-static.
Default value for instance variable:
int = 0
float,double = 0.0
reference variable = null
char = 0 (space character)
boolean = false
$full_path = WP_PLUGIN_URL . '/'. str_replace( basename( __FILE__ ), "", plugin_basename(__FILE__) );
This link may help: http://codex.wordpress.org/Determining_Plugin_and_Content_Directories.
In this case, one of the easiest and best approach is to first cast it to list
and then use where
or select
.
result = result.ToList().where(p => date >= p.DOB);
You can get this type of error if you add third party libraries in your project that require native frameworks not included in your project.
You need to look inside the .h and .m files of your newly added library and see what frameworks it requires, then include those frameworks in your project (Target > Build Phases > Link Binary With Libraries).

Declaring the field as 'final' will ensure that the field is a constant and cannot change. The difference comes in the usage of 'static' keyword.
Declaring a field as static means that it is associated with the type and not with the instances. i.e. only one copy of the field will be present for all the objects and not individual copy for each object. Due to this, the static fields can be accessed through the class name.
As you can see, your requirement that the field should be constant is achieved in both cases (declaring the field as 'final' and as 'static final').
Similar question is private final static attribute vs private final attribute

You have your storyboard set up to expect an outlet called tableView
but the actual outlet name is myTableView
.
If you delete the connection in the storyboard and reconnect to the right variable name, it should fix the problem.
The way that the language manages lexical scope creates issues with including both goto
and continue
. For example,
local a=0
repeat
if f() then
a=1 --change outer a
end
local a=f() -- inner a
until a==0 -- test inner a
The declaration of local a
inside the loop body masks the outer variable named a
, and the scope of that local extends across the condition of the until
statement so the condition is testing the innermost a
.
If continue
existed, it would have to be restricted semantically to be only valid after all of the variables used in the condition have come into scope. This is a difficult condition to document to the user and enforce in the compiler. Various proposals around this issue have been discussed, including the simple answer of disallowing continue
with the repeat ... until
style of loop. So far, none have had a sufficiently compelling use case to get them included in the language.
The work around is generally to invert the condition that would cause a continue
to be executed, and collect the rest of the loop body under that condition. So, the following loop
-- not valid Lua 5.1 (or 5.2)
for k,v in pairs(t) do
if isstring(k) then continue end
-- do something to t[k] when k is not a string
end
could be written
-- valid Lua 5.1 (or 5.2)
for k,v in pairs(t) do
if not isstring(k) then
-- do something to t[k] when k is not a string
end
end
It is clear enough, and usually not a burden unless you have a series of elaborate culls that control the loop operation.
You can also affect differente DOM elements using :target pseudo class. If an element is the destination of an anchor target it will get the :target pseudo element.
<style>
p { color:black; }
p:target { color:red; }
</style>
<a href="#elem">Click me</a>
<p id="elem">And I will change</p>
Here is a fiddle : https://jsfiddle.net/k86b81jv/
I would choose Sequelize because of it's excellent documentation. It's just a honest opinion (I never really used MySQL with Node that much).
This is such a common problem, especially in GUI applications, that I'm surprised there isn't a BCL class to do this out of the box. Here's how I do it.
public static class ReflectiveEnumerator
{
static ReflectiveEnumerator() { }
public static IEnumerable<T> GetEnumerableOfType<T>(params object[] constructorArgs) where T : class, IComparable<T>
{
List<T> objects = new List<T>();
foreach (Type type in
Assembly.GetAssembly(typeof(T)).GetTypes()
.Where(myType => myType.IsClass && !myType.IsAbstract && myType.IsSubclassOf(typeof(T))))
{
objects.Add((T)Activator.CreateInstance(type, constructorArgs));
}
objects.Sort();
return objects;
}
}
A few notes:
Assembly.GetAssembly(typeof(T))
because your base class might be in a different assembly. type.IsClass
and !type.IsAbstract
because it'll throw an exception if you try to instantiate an interface or abstract class.IComparable
so that they can be sorted.I have done with below single git command:
git clone [url] -b [branch-name] --single-branch
Consider this to get a fully unique jar file:
I always use the ISO 8601 format (e.g. 2008-10-31T15:07:38.6875000-05:00
) -- date.ToString("o")
. It is the XSD date format as well. That is the preferred format and a Standard Date and Time Format string, although you can use a manual format string if necessary if you don't want the 'T' between the date and time: date.ToString("yyyy-MM-dd HH:mm:ss");
EDIT: If you are using a generated class from an XSD or Web Service, you can just assign the DateTime instance directly to the class property. If you are writing XML text, then use the above.
Services are singletons, and it is not logical for a scope to be injected in service (which is case indeed, you cannot inject scope in service). You can pass scope as a parameter, but that is also a bad design choice, because you would have scope being edited in multiple places, making it hard for debugging. Code for dealing with scope variables should go in controller, and service calls go to the service.

// Use relative path for Unix systems
File f = new File(path);
f.getParentFile().mkdirs();
f.createNewFile();

Though I upvoted the answer marked as correct. I wanted to touch on a few things for anyone stumbling upon this.
In general, if you're filtering specifically on Date values alone. Microsoft recommends using the language neutral format of ymd
or y-m-d
.
Note that the form '2007-02-12' is considered language-neutral only for the data types DATE, DATETIME2, and DATETIMEOFFSET.
To do a date comparison using the aforementioned approach is simple. Consider the following, contrived example.
--112 is ISO format 'YYYYMMDD'
declare @filterDate char(8) = CONVERT(char(8), GETDATE(), 112)
select
*
from
Sales.Orders
where
CONVERT(char(8), OrderDate, 112) = @filterDate
In a perfect world, performing any manipulation to the filtered column should be avoided because this can prevent SQL Server from using indexes efficiently. That said, if the data you're storing is only ever concerned with the date and not time, consider storing as DATETIME
with midnight as the time. Because:
When SQL Server converts the literal to the filtered column’s type, it assumes midnight when a time part isn’t indicated. If you want such a filter to return all rows from the specified date, you need to ensure that you store all values with midnight as the time.
Thus, assuming you are only concerned with date, and store your data as such. The above query can be simplified to:
--112 is ISO format 'YYYYMMDD'
declare @filterDate char(8) = CONVERT(char(8), GETDATE(), 112)
select
*
from
Sales.Orders
where
OrderDate = @filterDate
Method 1 : Using jQuery Ajax Get call (partial page update).
Suitable for when you need to retrieve jSon data from database.
Controller's Action Method
[HttpGet]
public ActionResult Foo(string id)
{
var person = Something.GetPersonByID(id);
return Json(person, JsonRequestBehavior.AllowGet);
}
Jquery GET
function getPerson(id) {
$.ajax({
url: '@Url.Action("Foo", "SomeController")',
type: 'GET',
dataType: 'json',
// we set cache: false because GET requests are often cached by browsers
// IE is particularly aggressive in that respect
cache: false,
data: { id: id },
success: function(person) {
$('#FirstName').val(person.FirstName);
$('#LastName').val(person.LastName);
}
});
}
Person class
public class Person
{
public string FirstName { get; set; }
public string LastName { get; set; }
}
Method 2 : Using jQuery Ajax Post call (partial page update).
Suitable for when you need to do partial page post data into database.
Post method is also same like above just replace [HttpPost]
on Action method and type as post
for jquery method.

Method 4 : As a Form Get scenario (full page update).
Suitable for when you need to Get data from database
Get method also same like above just replace [HttpGet]
on Action method and FormMethod.Get
for View's form method.
I hope this will help to you.
2 more solutions I had luck with when neither tab close + reopening the page in another tab nor closing all tabs in Chrome (and the browser) then restarting it didn't work:
1) I fixed it on my machine by closing the tab, force-closing Chrome, & restarting the browser without restoring tabs (Note: on a computer running CentOS Linux).
2) My boss (also on CentOS) had the same issue (alerts are a big part of my company's Javascript debugging process for numerous reasons e.g. legacy), but my 1st method didn't work for him. However, I managed to fix it for him with the following process:
a) Make an empty text file called FixChrome.sh, and paste in the following bash script:
#! /bin/bash
cd ~/.config/google-chrome/Default //adjust for your Chrome install location
rm Preferences
rm 'Current Session'
rm 'Current Tabs'
rm 'Last Session'
rm 'Last Tabs'
b) close Chrome, then open Terminal and run the script (bash FixChrome.sh).
It worked for him. Downside is that you lose all tabs from your current & previous session, but it's worth it if this matters to you.
Try
document.head.innerHTML += '<meta http-equiv="X-UA-..." content="IE=edge">'
_x000D_
git log -n1 --format="Last committed item in this release was by %an, `git log -n1 --format=%at | awk '{print strftime("%y%m%d%H%M",$1)}'`, message: %s (%h) [%d]"
Since I needed this as well, I'll go into more detail on how to do this.
Note: I assume you used the standard template form for generating your UIPageViewController
structure - which has both the modelViewController
and dataViewController
created when you invoke it. If you don't understand what I wrote - go back and create a new project that uses the UIPageViewController
as it's basis. You'll understand then.
So, needing to flip to a particular page involves setting up the various pieces of the method listed above. For this exercise, I'm assuming that it's a landscape view with two views showing. Also, I implemented this as an IBAction so that it could be done from a button press or what not - it's just as easy to make it selector call and pass in the items needed.
So, for this example you need the two view controllers that will be displayed - and optionally, whether you're going forward in the book or backwards.
Note that I merely hard-coded where to go to pages 4 & 5 and use a forward slip. From here you can see that all you need to do is pass in the variables that will help you get these items...
-(IBAction) flipToPage:(id)sender {
// Grab the viewControllers at position 4 & 5 - note, your model is responsible for providing these.
// Technically, you could have them pre-made and passed in as an array containing the two items...
DataViewController *firstViewController = [self.modelController viewControllerAtIndex:4 storyboard:self.storyboard];
DataViewController *secondViewController = [self.modelController viewControllerAtIndex:5 storyboard:self.storyboard];
// Set up the array that holds these guys...
NSArray *viewControllers = nil;
viewControllers = [NSArray arrayWithObjects:firstViewController, secondViewController, nil];
// Now, tell the pageViewContoller to accept these guys and do the forward turn of the page.
// Again, forward is subjective - you could go backward. Animation is optional but it's
// a nice effect for your audience.
[self.pageViewController setViewControllers:viewControllers direction:UIPageViewControllerNavigationDirectionForward animated:YES completion:NULL];
// Voila' - c'est fin!
}
I got this error when I put a space before a comma in the parameters when calling a function.
eg, I used:
myfunction(parameter1: parameter1 , parameter2: parameter2)
Whereas it should have been:
myfunction(parameter1: parameter1, parameter2: parameter2)
Deleting the space got rid of the error message
Try an OUTER APPLY
SELECT
C.Content_ID,
C.Content_Title,
C.Content_DatePublished,
M.Media_Id
FROM
tbl_Contents C
OUTER APPLY
(
SELECT TOP 1 *
FROM tbl_Media M
WHERE M.Content_Id = C.Content_Id
) m
ORDER BY
C.Content_DatePublished ASC
Alternatively, you could GROUP BY
the results
SELECT
C.Content_ID,
C.Content_Title,
C.Content_DatePublished,
M.Media_Id
FROM
tbl_Contents C
LEFT OUTER JOIN tbl_Media M ON M.Content_Id = C.Content_Id
GROUP BY
C.Content_ID,
C.Content_Title,
C.Content_DatePublished,
M.Media_Id
ORDER BY
C.Content_DatePublished ASC
The OUTER APPLY
selects a single row (or none) that matches each row from the left table.
The GROUP BY
performs the entire join, but then collapses the final result rows on the provided columns.
I am a Python beginner, but an experienced programmer. I have Python 3.5, so I can just use the comma, but this is nonetheless an interesting programming exercise. Consider the case of an unsigned integer. The most readable Python program for adding thousands separators appears to be:
def add_commas(instr):
out = [instr[0]]
for i in range(1, len(instr)):
if (len(instr) - i) % 3 == 0:
out.append(',')
out.append(instr[i])
return ''.join(out)
It is also possible to use a list comprehension:
add_commas(instr):
rng = reversed(range(1, len(instr) + (len(instr) - 1)//3 + 1))
out = [',' if j%4 == 0 else instr[-(j - j//4)] for j in rng]
return ''.join(out)
This is shorter, and could be a one liner, but you will have to do some mental gymnastics to understand why it works. In both cases we get:
for i in range(1, 11):
instr = '1234567890'[:i]
print(instr, add_commas(instr))
1 1
12 12
123 123
1234 1,234
12345 12,345
123456 123,456
1234567 1,234,567
12345678 12,345,678
123456789 123,456,789
1234567890 1,234,567,890
The first version is the more sensible choice, if you want the program to be understood.
An alternative - which may work for you depending on what you're trying to do - is to have the HTML in place and then use the CSS to show or hide it depending on the class of a parent element.
OR
Use jQuery append()
There's a property for that:
a.m_title {
text-transform: capitalize;
}
If your links can contain multiple words and you only want the first letter of the first word to be uppercase, use :first-letter
with a different transform instead (although it doesn't really matter). Note that in order for :first-letter
to work your a
elements need to be block containers (which can be display: block
, display: inline-block
, or any of a variety of other combinations of one or more properties):
a.m_title {
display: block;
}
a.m_title:first-letter {
text-transform: uppercase;
}
Abstract Method:
If an abstract method is defined in a class, then the class should declare as an abstract class.
An abstract method should contain only method definition, should not Contain the method body/implementation.
An abstract method must be over ride in the derived class.
Virtual Method:
Example:
public abstract class baseclass
{
public abstract decimal getarea(decimal Radius);
public virtual decimal interestpermonth(decimal amount)
{
return amount*12/100;
}
public virtual decimal totalamount(decimal Amount,decimal principleAmount)
{
return Amount + principleAmount;
}
}
public class derivedclass:baseclass
{
public override decimal getarea(decimal Radius)
{
return 2 * (22 / 7) * Radius;
}
public override decimal interestpermonth(decimal amount)
{
return amount * 14 / 100;
}
}
None of the above worked for me but I came up with this and it worked:
function toggleChevron(el) {
if ($(el).find('i').hasClass('icon-chevron-left'))
$(el).find('.icon-chevron-left').removeClass("icon-chevron-left").addClass("icon-chevron-down");
else
$(el).find('.icon-chevron-down').removeClass("icon-chevron-down").addClass("icon-chevron-left");
}
HTML implementation:
<div class="accordion" id="accordion-send">
<div class="accordion-group">
<div class="accordion-heading" onClick="toggleChevron(this)">
<a class="accordion-toggle" data-toggle="collapse" data-parent="#accordion-send" href="#collapse-refund">
<i class="icon icon-chevron-right"></i> Send notice
</a>
...
New to Python 3.2 is functools.lru_cache
. By default, it only caches the 128 most recently used calls, but you can set the maxsize
to None
to indicate that the cache should never expire:
import functools
@functools.lru_cache(maxsize=None)
def fib(num):
if num < 2:
return num
else:
return fib(num-1) + fib(num-2)
This function by itself is very slow, try fib(36)
and you will have to wait about ten seconds.
Adding lru_cache
annotation ensures that if the function has been called recently for a particular value, it will not recompute that value, but use a cached previous result. In this case, it leads to a tremendous speed improvement, while the code is not cluttered with the details of caching.

Not sure if this will help, but I usually pull the command prompt up by going into "Synchronization" tab in Team Explorer and clicking on "Actions"
When the command prompt opens it is in the directory of the project.
This works for me:
if(!driver.findElements(By.xpath("//*[@id='submit']")).isEmpty()){
//THEN CLICK ON THE SUBMIT BUTTON
}else{
//DO SOMETHING ELSE AS SUBMIT BUTTON IS NOT THERE
}
You need to save the PID of the background process at the time you start it:
foo &
FOO_PID=$!
# do other stuff
kill $FOO_PID
You cannot use job control, since that is an interactive feature and tied to a controlling terminal. A script will not necessarily have a terminal attached at all so job control will not necessarily be available.
I had referenced this article and many others and did not find a clear cut concise response to help. I am offering my discovery, arrived at with some references from this thread, in the following:
Spring-Boot version: 1.3.5.RELEASE
Spring-Core version: 4.2.6.RELEASE
Dependency Management: Brixton.SR1
The following is the pertinent yaml excerpt:
tools:
toolList:
-
name: jira
matchUrl: http://someJiraUrl
-
name: bamboo
matchUrl: http://someBambooUrl
I created a Tools.class:
@Component
@ConfigurationProperties(prefix = "tools")
public class Tools{
private List<Tool> toolList = new ArrayList<>();
public Tools(){
//empty ctor
}
public List<Tool> getToolList(){
return toolList;
}
public void setToolList(List<Tool> tools){
this.toolList = tools;
}
}
I created a Tool.class:
@Component
public class Tool{
private String name;
private String matchUrl;
public Tool(){
//empty ctor
}
public String getName(){
return name;
}
public void setName(String name){
this.name= name;
}
public String getMatchUrl(){
return matchUrl;
}
public void setMatchUrl(String matchUrl){
this.matchUrl= matchUrl;
}
@Override
public String toString(){
StringBuffer sb = new StringBuffer();
String ls = System.lineSeparator();
sb.append(ls);
sb.append("name: " + name);
sb.append(ls);
sb.append("matchUrl: " + matchUrl);
sb.append(ls);
}
}
I used this combination in another class through @Autowired
@Component
public class SomeOtherClass{
private Logger logger = LoggerFactory.getLogger(SomeOtherClass.class);
@Autowired
private Tools tools;
/* excluded non-related code */
@PostConstruct
private void init(){
List<Tool> toolList = tools.getToolList();
if(toolList.size() > 0){
for(Tool t: toolList){
logger.info(t.toString());
}
}else{
logger.info("*****----- tool size is zero -----*****");
}
}
/* excluded non-related code */
}
And in my logs the name and matching url's were logged. This was developed on another machine and thus I had to retype all of the above so please forgive me in advance if I inadvertently mistyped.
I hope this consolidation comment is helpful to many and I thank the previous contributors to this thread!
New, improved answer to an old, frequently asked question...
Double quote ("

In XML textual content:
<NoEscapeNeeded>He said, "Don't quote me."</NoEscapeNeeded>
In XML attributes delimited by single quotes ('
):
<NoEscapeNeeded name='Pete "Maverick" Mitchell'/>
Note: switching to single quotes ('
) also requires no escaping:
<NoEscapeNeeded name="Pete 'Maverick' Mitchell"/>
Double quote ("

In XML attributes delimited by double quotes:
<EscapeNeeded name="Pete "Maverick" Mitchell"/>
Double quote ("

in XML only in very limited contexts.
Wildcards (asterisks) ARE NOT allowed in the subdomain part.

Here's what's actually happening localhost means that you want to open htdocs. First it will search for any file named index.php or index.html. If one of those exist it will open the file. If neither of those exist then it will open all folder/file inside htdocs directory which is what you want.
So, the simplest solution is to rename index.php or index.html to index2.php etc.
The player_api will be deprecated on Jun 25, 2015. For play youtube videos there is a new api IFRAME_API

<script>
// 2. This code loads the IFrame Player API code asynchronously.
var tag = document.createElement('script');
tag.src = "https://www.youtube.com/iframe_api";
var firstScriptTag = document.getElementsByTagName('script')[0];
firstScriptTag.parentNode.insertBefore(tag, firstScriptTag);
// 3. This function creates an <iframe> (and YouTube player)

});
}
// 4. The API will call this function when the video player is ready.
function onPlayerReady(event) {

%lld
is the standard C99 way, but that doesn't work on the compiler that I'm using (mingw32-gcc v4.6.0). The way to do it on this compiler is: %I64d
So try this:
if(e%n==0)printf("%15I64d -> %1.16I64d\n",e, 4*pi);
and
scanf("%I64d", &n);
The only way I know of for doing this in a completely portable way is to use the defines in <inttypes.h>
.
In your case, it would look like this:
scanf("%"SCNd64"", &n);
//...
if(e%n==0)printf("%15"PRId64" -> %1.16"PRId64"\n",e, 4*pi);
It really is very ugly... but at least it is portable.
This can be done with a CSS hack (see the other answers), but it can also be done very easily with JavaScript.
Set the div's width to (for example) 50%, use JavaScript to check its width, and then set the height accordingly. Here's a code example using jQuery:
$(function() {_x000D_
var div = $('#dynamicheight');_x000D_
var width = div.width();_x000D_
_x000D_
div.css('height', width);_x000D_
});
_x000D_
#dynamicheight_x000D_
{_x000D_
width: 50%;_x000D_
_x000D_
/* Just for looks: */_x000D_
background-color: cornflowerblue;_x000D_
margin: 25px;_x000D_
}
_x000D_
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>_x000D_
_x000D_
<div id="dynamicheight"></div>
_x000D_
If you want the box to scale with the browser window on resize, move the code to a function and call it on the window resize event. Here's a demonstration of that too (view example full screen and resize browser window):
$(window).ready(updateHeight);_x000D_
$(window).resize(updateHeight);_x000D_
_x000D_
function updateHeight()_x000D_
{_x000D_
var div = $('#dynamicheight');_x000D_
var width = div.width();_x000D_
_x000D_
div.css('height', width);_x000D_
}
_x000D_
#dynamicheight_x000D_
{_x000D_
width: 50%;_x000D_
_x000D_
/* Just for looks: */_x000D_
background-color: cornflowerblue;_x000D_
margin: 25px;_x000D_
}
_x000D_
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>_x000D_
_x000D_
<div id="dynamicheight"></div>

typedef
is useful for redefining the name of an existing variable type. It provides short & meaningful way to call a datatype.
e.g:
typedef unsigned long int TWOWORDS;
here, the type unsigned long int is redefined to be of the type TWOWORDS. Thus, we can now declare variables of type unsigned long int by writing,
TWOWORDS var1, var2;
instead of
unsigned long int var1, var2;
To reference a package and remove various "keys", try this
db['name1.name2.name3.Properties'].remove([
{
"key" : "name_key1"
},
{
"key" : "name_key2"
},
{
"key" : "name_key3"
}
)]
What about 1.1E10, +1, -0, etc? Parsing all possible numbers is trickier than many people think. If you want to include as many numbers are possible you should use the to_number function in a PL/SQL function. From http://www.oracle-developer.net/content/utilities/is_number.sql:
CREATE OR REPLACE FUNCTION is_number (str_in IN VARCHAR2) RETURN NUMBER IS
n NUMBER;
BEGIN
n := TO_NUMBER(str_in);
RETURN 1;
EXCEPTION
WHEN VALUE_ERROR THEN
RETURN 0;
END;

For classes that you create (ie. are not part of the Android) its possible to avoid the crash completely.
Any class that implements finalize()
has some unavoidable probability of crashing as explained by @oba. So instead of using finalizers to perform cleanup, use a PhantomReferenceQueue
.
For an example check out the implementation in React Native: https://github.com/facebook/react-native/blob/master/ReactAndroid/src/main/java/com/facebook/jni/DestructorThread.java
(I'm not completely happy with the answers so far, so here is my attempt...)
I think that Kevin Wright's comment ("You can make a Promise and it's up to you to keep it. When someone else makes you a promise you must wait to see if they honour it in the Future") summarizes it pretty well, but some explanation can be useful.
Futures and promises are pretty similar concepts, the difference is that a future is a read-only container for a result that does not yet exist, while a promise can be written (normally only once). The Java 8 CompletableFuture and the Guava SettableFuture can be thought of as promises, because their value can be set ("completed"), but they also implement the Future interface, therefore there is no difference for the client.
The result of the future will be set by "someone else" - by the result of an asynchronous computation. Note how FutureTask - a classic future - must be initialized with a Callable or Runnable, there is no no-argument constructor, and both Future and FutureTask are read-only from the outside (the set methods of FutureTask are protected). The value will be set to the result of the computation from the inside.
On the other hand, the result of a promise can be set by "you" (or in fact by anybody) anytime because it has a public setter method. Both CompletableFuture and SettableFuture can be created without any task, and their value can be set at any time. You send a promise to the client code, and fulfill it later as you wish.
Note that CompletableFuture is not a "pure" promise, it can be initialized with a task just like FutureTask, and its most useful feature is the unrelated chaining of processing steps.
Also note that a promise does not have to be a subtype of future and it does not have to be the same object. In Scala a Future object is created by an asynchronous computation or by a different Promise object. In C++ the situation is similar: the promise object is used by the producer and the future object by the consumer. The advantage of this separation is that the client cannot set the value of the future.
Both Spring and EJB 3.1 have an AsyncResult class, which is similar to the Scala/C++ promises. AsyncResult does implement Future but this is not the real future: asynchronous methods in Spring/EJB return a different, read-only Future object through some background magic, and this second "real" future can be used by the client to access the result.
I needed to iterate through the end of an array and didn't want to copy the array. My approach was to make an Iterable over the array.
public static Iterable<String> sliceArray(final String[] array,
final int start) {
return new Iterable<String>() {
String[] values = array;
int posn = start;
@Override
public Iterator<String> iterator() {
return new Iterator<String>() {
@Override
public boolean hasNext() {
return posn < values.length;
}
@Override
public String next() {
return values[posn++];
}
@Override
public void remove() {
throw new UnsupportedOperationException("No remove");
}
};
}
};
}
When you do new Promise((resolve)...
the type inferred was Promise<{}>
because you should have used new Promise<number>((resolve)
.
It is interesting that this issue was only highlighted when the async
keyword was added. I would recommend reporting this issue to the TS team on GitHub.
There are many ways you can get around this issue. All the following functions have the same behavior:
const whatever1 = () => {
return new Promise<number>((resolve) => {
resolve(4);
});
};
const whatever2 = async () => {
return new Promise<number>((resolve) => {
resolve(4);
});
};
const whatever3 = async () => {
return await new Promise<number>((resolve) => {
resolve(4);
});
};
const whatever4 = async () => {
return Promise.resolve(4);
};
const whatever5 = async () => {
return await Promise.resolve(4);
};
const whatever6 = async () => Promise.resolve(4);
const whatever7 = async () => await Promise.resolve(4);
In your IDE you will be able to see that the inferred type for all these functions is () => Promise<number>
.
This works perfectly fine with me :)
Path.GetFileName(path.TrimEnd('\\')
I solve this problem by always using the [h]
option on floats (such as figures) so that they (mostly) go where I place them. Then when I look at the final draft, I adjust the location of the float by moving it in the LaTeX source. Usually that means moving it around the paragraph where it is referenced. Sometimes I need to add a page break at an appropriate spot.
I've found that the default placement of floats is reasonable in LaTeX, but manual adjustments are almost always needed to get things like this just right. (And sometimes it isn't possible for everything to be perfect when there are lots of floats and footnotes.)
The manual for the memoir
class has some good information about how LaTeX places floats and some advice for manipulating the algorithm.
By default Vagrant uses a generated private key to login, you can try this:
ssh -l ubuntu -p 2222 -i .vagrant/machines/default/virtualbox/private_key 127.0.0.1
After thinking this through carefully, I think this is the best way. It lets you step off in the middle easily without using break
, which I think is important, and it requires minimal computation, so I think it's the fastest. It also doesn't require that li
be a list or tuple. It could be any iterator.
from itertools import cycle
li = [0, 1, 2, 3]
running = True
licycle = cycle(li)
# Prime the pump
nextelem = next(licycle)
while running:
thiselem, nextelem = nextelem, next(licycle)
I'm leaving the other solutions here for posterity.
All of that fancy iterator stuff has its place, but not here. Use the % operator.
li = [0, 1, 2, 3]
running = True
while running:
for idx, elem in enumerate(li):
thiselem = elem
nextelem = li[(idx + 1) % len(li)]
Now, if you intend to infinitely cycle through a list, then just do this:
li = [0, 1, 2, 3]
running = True
idx = 0
while running:
thiselem = li[idx]
idx = (idx + 1) % len(li)
nextelem = li[idx]
I think that's easier to understand than the other solution involving tee
, and probably faster too. If you're sure the list won't change size, you can squirrel away a copy of len(li)
and use that.
This also lets you easily step off the ferris wheel in the middle instead of having to wait for the bucket to come down to the bottom again. The other solutions (including yours) require you check running
in the middle of the for
loop and then break
.
Here:
Note: Calling a lifecycle method from another one is not a good practice. In below example I tried to achieve that your onNewIntent will be always called irrespective of your Activity type.
OnNewIntent() always get called for singleTop/Task activities except for the first time when activity is created. At that time onCreate is called providing to solution for few queries asked on this thread.
You can invoke onNewIntent always by putting it into onCreate method like
@Override
public void onCreate(Bundle savedState){
super.onCreate(savedState);
onNewIntent(getIntent());
}
@Override
protected void onNewIntent(Intent intent) {
super.onNewIntent(intent);
//code
}
If any other solution is in the debug mode then first stop them all and after that restart the visual studio. It worked for me.
I just wanna add this, when you access the position of the array like
arg[n]
is the same as
*(arg + n)
than means an offset of n starting from de arg address.
so arg[0]
will be *arg
To clear things up a little, since some of the answers are providing incorrect information:
The jQuery .css() method allows the use of either DOM or CSS notation in many cases. So, both backgroundColor
and background-color
will get the job done.
Additionally, when you call .css()
with arguments you have two choices as to what the arguments can be. They can either be 2 comma separated strings representing a css property and its value, or it can be a Javascript object containing one or more key value pairs of CSS properties and values.
In conclusion the only thing wrong with your code is a missing }
. The line should read:
$("#myParagraph").css({"backgroundColor":"black","color":"white"});
You cannot leave the curly brackets out, but you may leave the quotes out from around backgroundColor
and color
. If you use background-color
you must put quotes around it because of the hyphen.
In general, it's a good habit to quote your Javascript objects, since problems can arise if you do not quote an existing keyword.
A final note is that about the jQuery .ready() method
$(handler);
is synonymous with:
$(document).ready(handler);
as well as with a third not recommended form.
This means that $(init)
is completely correct, since init
is the handler in that instance. So, init
will be fired when the DOM is constructed.
I suspect the condition you are looking for is DUP_VAL_ON_INDEX

By comparing the solution below with the one that uses cumsum of numpy, This one takes almost half the time. This is because it does not need to go through the entire array to do the cumsum and then do all the subtraction. Moreover, the cumsum can be "dangerous" if the array is huge and the number are huge (possible overflow). Of course, also here the danger exists but at least are summed together only the essential numbers.
def moving_average(array_numbers, n):
if n > len(array_numbers):
return []
temp_sum = sum(array_numbers[:n])
averages = [temp_sum / float(n)]
for first_index, item in enumerate(array_numbers[n:]):
temp_sum += item - array_numbers[first_index]
averages.append(temp_sum / float(n))
return averages

taskkill /F /PID
But it won't work for me
then I tried taskkill -PID <processorid> -F
Example:- taskkill -PID 33192 -F
Here 33192 is the processorid and it works
Existing answers did a great job at explaining the what of this reverse()
function in Django.
However, I'd hoped that my answer shed a different light at the why: why use reverse()
in place of other more straightforward, arguably more pythonic approaches in template-view binding, and what are some legitimate reasons for the popularity of this "redirect via reverse()
pattern" in Django routing logic.
One key benefit is the reverse construction of a url, as others have mentioned. Just like how you would use {% url "profile" profile.id %}
to generate the url from your app's url configuration file: e.g. path('<int:profile.id>/profile', views.profile, name="profile")
.
But as the OP have noted, the use of reverse()
is also commonly combined with the use of HttpResponseRedirect
. But why?
I am not quite sure what this is but it is used together with HttpResponseRedirect. How and when is this reverse() supposed to be used?
Consider the following views.py
:
from django.http import HttpResponseRedirect
from django.urls import reverse
def vote(request, question_id):
question = get_object_or_404(Question, pk=question_id)
try:
selected = question.choice_set.get(pk=request.POST['choice'])
except KeyError:
# handle exception
pass
else:
selected.votes += 1
selected.save()
return HttpResponseRedirect(reverse('polls:polls-results',
args=(question.id)
))
And our minimal urls.py
:
from django.urls import path
from . import views
app_name = 'polls'
urlpatterns = [
path('<int:question_id>/results/', views.results, name='polls-results'),
path('<int:question_id>/vote/', views.vote, name='polls-vote')
]
In the vote()
function, the code in our else
block uses reverse
along with HttpResponseRedirect
in the following pattern:
HttpResponseRedirect(reverse('polls:polls-results',
args=(question.id)
This first and foremost, means we don't have to hardcode the URL (consistent with the DRY principle) but more crucially, reverse()
provides an elegant way to construct URL strings by handling values unpacked from the arguments (args=(question.id)
is handled by URLConfig). Supposed question
has an attribute id
which contains the value 5
, the URL constructed from the reverse()
would then be:
'/polls/5/results/'
In normal template-view binding code, we use HttpResponse()
or render()
as they typically involve less abstraction: one view function returning one template:
def index(request):
return render(request, 'polls/index.html')
But in many legitimate cases of redirection, we typically care about constructing the URL from a list of parameters. These include cases such as:
POST
requestMost of these involve some form of redirection, and a URL constructed through a set of parameters. Hope this adds to the already helpful thread of answers!
where T: class
literally means that T has to be a class
. It can be any reference type. Now whenever any code calls your DoThis<T>()
method it must provide a class to replace T. For example if I were to call your DoThis<T>()
method then I will have to call it like following:
DoThis<MyClass>();
If your metthod is like like the following:
public IList<T> DoThis<T>() where T : class
{
T variablename = new T();
// other uses of T as a type
}
Then where ever T appears in your method, it will be replaced by MyClass. So the final method that the compiler calls , will look like the following:
public IList<MyClass> DoThis<MyClass>()
{
MyClass variablename= new MyClass();
//other uses of MyClass as a type
// all occurences of T will similarly be replace by MyClass
}
SqlDependency doesn't watch the database it watches the SqlCommand you specify so if you are trying to lets say insert values into the database in 1 project and capture that event in another project it won't work because the event was from the SqlCommand from the 1º project not the database because when you create an SqlDependency you link it to a SqlCommand and only when that command from that project is used does it create a Change event.
I think it will be better, just serialize your form by jquery and cheers...
<form id="ajxForm">
<!-- input elments here -->
<textarea id="ck-editor" name="ck-editor" required></textarea>
<input name="text" id="text" type="text" required>
<form>
and In javascript section
CKEDITOR.replace('ck-editor', {
extraPlugins: 'sourcedialog',
removePlugins: 'sourcearea'
});
$("form#ajxForm").submit(function(e) {
e.preventDefault();
var data = $(this).serialize();
if (data != '') {
$.ajax({
url: 'post.php',
cache: false,
type: 'POST',
data: data,
success: function(e) {
setTimeout(function() {
alert(e);
}, 6500);
}
});
}
return;
});
The simplest way is using libraries like google-http-java-client but if you want parse the JSON response by yourself you can do that in a multiple ways, you can use org.json, json-simple, Gson, minimal-json, jackson-mapper-asl (from 1.x)... etc
A set of simple examples:
Using Gson:
import java.io.IOException;
import org.apache.http.HttpResponse;
import org.apache.http.client.methods.HttpPost;
import org.apache.http.entity.StringEntity;
import org.apache.http.impl.client.CloseableHttpClient;
import org.apache.http.impl.client.HttpClientBuilder;
import org.apache.http.util.EntityUtils;
public class Gson {
public static void main(String[] args) {
}
public HttpResponse http(String url, String body) {
try (CloseableHttpClient httpClient = HttpClientBuilder.create().build()) {
HttpPost request = new HttpPost(url);
StringEntity params = new StringEntity(body);
request.addHeader("content-type", "application/json");
request.setEntity(params);
HttpResponse result = httpClient.execute(request);
String json = EntityUtils.toString(result.getEntity(), "UTF-8");
com.google.gson.Gson gson = new com.google.gson.Gson();
Response respuesta = gson.fromJson(json, Response.class);
System.out.println(respuesta.getExample());
System.out.println(respuesta.getFr());
} catch (IOException ex) {
}
return null;
}
public class Response{
private String example;
private String fr;
public String getExample() {
return example;
}
public void setExample(String example) {
this.example = example;
}
public String getFr() {
return fr;
}
public void setFr(String fr) {
this.fr = fr;
}
}
}
Using json-simple:
import java.io.IOException;
import org.apache.http.HttpResponse;
import org.apache.http.client.methods.HttpPost;
import org.apache.http.entity.StringEntity;
import org.apache.http.impl.client.CloseableHttpClient;
import org.apache.http.impl.client.HttpClientBuilder;
import org.apache.http.util.EntityUtils;
import org.json.simple.JSONArray;
import org.json.simple.JSONObject;
import org.json.simple.parser.JSONParser;
public class JsonSimple {
public static void main(String[] args) {
}
public HttpResponse http(String url, String body) {
try (CloseableHttpClient httpClient = HttpClientBuilder.create().build()) {
HttpPost request = new HttpPost(url);
StringEntity params = new StringEntity(body);
request.addHeader("content-type", "application/json");
request.setEntity(params);
HttpResponse result = httpClient.execute(request);
String json = EntityUtils.toString(result.getEntity(), "UTF-8");
try {
JSONParser parser = new JSONParser();
Object resultObject = parser.parse(json);
if (resultObject instanceof JSONArray) {
JSONArray array=(JSONArray)resultObject;
for (Object object : array) {
JSONObject obj =(JSONObject)object;
System.out.println(obj.get("example"));
System.out.println(obj.get("fr"));
}
}else if (resultObject instanceof JSONObject) {
JSONObject obj =(JSONObject)resultObject;
System.out.println(obj.get("example"));
System.out.println(obj.get("fr"));
}
} catch (Exception e) {
// TODO: handle exception
}
} catch (IOException ex) {
}
return null;
}
}
etc...
In all these scenarios outerScopeVar
is modified or assigned a value asynchronously or happening in a later time(waiting or listening for some event to occur),for which the current execution will not wait.So all these cases current execution flow results in outerScopeVar = undefined
Let's discuss each examples(I marked the portion which is called asynchronously or delayed for some events to occur):
1.
Here we register an eventlistner which will be executed upon that particular event.Here loading of image.Then the current execution continuous with next lines img.src = 'lolcat.png';
and alert(outerScopeVar);
meanwhile the event may not occur. i.e, funtion img.onload
wait for the referred image to load, asynchrously. This will happen all the folowing example- the event may differ.
2.
Here the timeout event plays the role, which will invoke the handler after the specified time. Here it is 0
, but still it registers an asynchronous event it will be added to the last position of the Event Queue
for execution, which makes the guaranteed delay.
3.
4.
Node can be consider as a king of asynchronous coding.Here the marked function is registered as a callback handler which will be executed after reading the specified file.
5.
Obvious promise (something will be done in future) is asynchronous. see What are the differences between Deferred, Promise and Future in JavaScript?

I am not familiar with JXL and but we use POI. POI is well maintained and can handle both the binary .xls format and the new xml based format that was introduced in Office 2007.
CSV files are not excel files, they are text based files, so these libraries don't read them. You will need to parse out a CSV file yourself. I am not aware of any CSV file libraries, but I haven't looked either.
For people who searched for php multidimensional array get values
and actually want to solve problem comes from getting one column value from a 2 dimensinal array (like me!), here's a much elegant way than using foreach
, which is array_column
For example, if I only want to get hotel_name
from the below array, and form to another array:
$hotels = [
[
'hotel_name' => 'Hotel A',
'info' => 'Hotel A Info',
],
[
'hotel_name' => 'Hotel B',
'info' => 'Hotel B Info',
]
];
I can do this using array_column
:
$hotel_name = array_column($hotels, 'hotel_name');
print_r($hotel_name); // Which will give me ['Hotel A', 'Hotel B']
For the actual answer for this question, it can also be beautified by array_column
and call_user_func_array('array_merge', $twoDimensionalArray);
Let's make the data in PHP:
$hotels = [
[
'hotel_name' => 'Hotel A',
'info' => 'Hotel A Info',
'rooms' => [
[
'room_name' => 'Luxury Room',
'bed' => 2,
'boards' => [
'board_id' => 1,
'price' => 200
]
],
[
'room_name' => 'Non Luxy Room',
'bed' => 4,
'boards' => [
'board_id' => 2,
'price' => 150
]
],
]
],
[
'hotel_name' => 'Hotel B',
'info' => 'Hotel B Info',
'rooms' => [
[
'room_name' => 'Luxury Room',
'bed' => 2,
'boards' => [
'board_id' => 3,
'price' => 900
]
],
[
'room_name' => 'Non Luxy Room',
'bed' => 4,
'boards' => [
'board_id' => 4,
'price' => 300
]
],
]
]
];
And here's the calculation:
$rooms = array_column($hotels, 'rooms');
$rooms = call_user_func_array('array_merge', $rooms);
$boards = array_column($rooms, 'boards');
foreach($boards as $board){
$board_id = $board['board_id'];
$price = $board['price'];
echo "Board ID is: ".$board_id." and price is: ".$price . "<br/>";
}
Which will give you the following result:
Board ID is: 1 and price is: 200
Board ID is: 2 and price is: 150
Board ID is: 3 and price is: 900
Board ID is: 4 and price is: 300
return false;
at the end of the onclick handler will do the job. However, it's be better to simply add type="button"
to the <button>
- that way it behaves properly even without any JavaScript.
You can use:
<asp:textbox id="textBox1" style="text-align:center"></asp:textbox>
Or this:
textbox.Style["text-align"] = "center"; //right, left

struct foo fun() {
struct foo fooObj;
...
return fooObj;
}
Option 2
: You can pass one of the two via pointer and make changes to the actual parameter through the pointer and return the other as usual:
int fun(char **param) {
int bar;
...
strcpy(*param,"....");
return bar;
}
or
char* fun(int *param) {
char *str = /* malloc suitably.*/
...
strcpy(str,"....");
*param = /* some value */
return str;
}
Option 3
: Similar to the option 2. You can pass both via pointer and return nothing from the function:
void fun(char **param1,int *param2) {
strcpy(*param1,"....");
*param2 = /* some calculated value */
}
If your query has any JOINs, Mysql Workbench will not allow you to alter the table, even if your results are all from a single table.
For example, the following query
SELECT u.* FROM users u JOIN passwords p ON u.id=p.user_id WHERE p.password IS NULL;
will not allow you to edit the results or add rows, even though the results are limited to one table. You must specifically do something like:
SELECT * FROM users WHERE id=1012;
and then you can edit the row and add rows to the table.
for superclasses with many members I would suggest you to use @Delegate
@Data
public class A {
@Delegate public class AInner{
private final int x;
private final int y;
}
}
@Data
@EqualsAndHashCode(callSuper = true)
public class B extends A {
private final int z;
public B(A.AInner a, int z) {
super(a);
this.z = z;
}
}

No jQuery needed! Just use the substring method:
var gorge = name.substring(4);
Or if the text you want to remove isn't static:
var name = 'nameGorge';
var toRemove = 'name';
var gorge = name.replace(toRemove,'');
As a suggestion, you also can use the QChar::digitValue()
to obtain the numeric value of the digit. For example:
for (int var = 0; var < myString.length(); ++var) {
bool ok;
if (myString.at(var).isDigit()){
int digit = myString.at(var).digitValue();
//DO SOMETHING HERE WITH THE DIGIT
}
}
Here's a quick way to do it, won't require anything besides sys
.. though functionality is limited:
flag = "--flag" in sys.argv[1:]
[1:]
is in case if the full file name is --flag
The C standard does not allow void pointer arithmetic. However, GNU C is allowed by considering the size of void is 1
.
C11 standard §6.2.5
Paragraph - 19
The
void
type comprises an empty set of values; it is an incomplete object type that cannot be completed.
Following program is working fine in GCC compiler.
#include<stdio.h>
int main()
{
int arr[2] = {1, 2};
void *ptr = &arr;
ptr = ptr + sizeof(int);
printf("%d\n", *(int *)ptr);
return 0;
}
May be other compilers generate an error.

You've used integers in the expression 7/10, and integer 7 divided by integer 10 is zero.
What you're expecting is floating point division. Any of the following would evaluate the way you expected:
7.0 / 10
7 / 10.0
7.0 / 10.0
7 / (double) 10
One method that uses less math/theory is to sample 2, 5, 7, or 10 data points at a time and determine those which are outliers. A less accurate measure of an outlier than a Kalman Filter is to to use the following algorithm to take all pair wise distances between points and throw out the one that is furthest from the the others. Typically those values are replaced with the value closest to the outlying value you are replacing
For example
Smoothing at five sample points A, B, C, D, E
ATOTAL = SUM of distances AB AC AD AE
BTOTAL = SUM of distances AB BC BD BE
CTOTAL = SUM of distances AC BC CD CE
DTOTAL = SUM of distances DA DB DC DE
ETOTAL = SUM of distances EA EB EC DE
If BTOTAL is largest you would replace point B with D if BD = min { AB, BC, BD, BE }
This smoothing determines outliers and can be augmented by using the midpoint of BD instead of point D to smooth the positional line. Your mileage may vary and more mathematically rigorous solutions exist.
According to the Javadoc of Scanner, it closes the stream when you call it's close method. Generally speaking, the code that creates a resource is also responsible for closing it. System.in was not instantiated by by your code, but by the VM. So in this case it's safe to not close the Scanner, ignore the warning and add a comment why you ignore it. The VM will take care of closing it if needed.
(Offtopic: instead of "amount", the word "number" would be more appropriate to use for a number of players. English is not my native language (I'm Dutch) and I used to make exactly the same mistake.)
Here is an illustration of your first import cycle problem.
project/controllers/account
^ \
/ \
/ \
/ \/
project/components/mux <--- project/controllers/base
As you can see with my bad ASCII chart is that you are creating an import cycle when project/components/mux
imports project/controllers/account
. Since Go does not support circular dependencies you get the import cycle not allowed
error during compile time.
I found that the accepted answer and the similar ones to it had some flaws. Mainly that it's repeatedly adding that mouseleave listener to the element.
I've combined their solution with some custom code to achieve the functionality in question without memory leaks or listener bloat.
var getPopoverTimeout = function ($el) {
return $el.data('timeout');
}
$element.popover({
trigger: "manual",
html: true,
content: ...,
title: ...,
container: $element
}).on("mouseenter", function () {
var $this = $(this);
if (!$this.find('.popover').length) {
$this.popover("show");
} else if (getPopoverTimeout($element)) {
clearTimeout(getPopoverTimeout($element));
}
}).on("mouseleave", function () {
var $this = $(this);
$element.data('timeout', setTimeout(function () {
if (!$(".popover:hover").length) {
$this.popover("hide")
}
}, 250));
});
Which provides a nice 'hover-intent' like solution so that it doesn't flash in and out.
You can also pass events down into child components with something like this:
<CustomComponent
@keyup.enter="handleKeyUp"
/>
...
<template>
<div>
<input
type="text"
v-on="$listeners"
>
</div>
</template>
<script>
export default {
name: 'CustomComponent',
mounted() {
console.log('listeners', this.$listeners)
},
}
</script>
That works well if you have a pass-through component and want the listeners to go onto a specific element.
.m2/repository
and delete the conflicting filesmvn -U clean install
You are dropping it, then creating it, then trying to create it again by using SELECT INTO
. Change to:
DROP TABLE #TMPGUARDIAN
CREATE TABLE #TMPGUARDIAN(
LAST_NAME NVARCHAR(30),
FRST_NAME NVARCHAR(30))
INSERT INTO #TMPGUARDIAN
SELECT LAST_NAME,FRST_NAME
FROM TBL_PEOPLE
In MS SQL Server you can create a table without a CREATE TABLE
statement by using SELECT INTO
Since the early release of Java 8, you could try something like:
Collection<T> collection = ...;
Stream<T> stream = collection.stream().filter(...);
For example, if you had a list of integers and you wanted to filter the numbers that are > 10 and then print out those numbers to the console, you could do something like:
List<Integer> numbers = Arrays.asList(12, 74, 5, 8, 16);
numbers.stream().filter(n -> n > 10).forEach(System.out::println);
Looks like you are missing a leading slash. Perhaps try:
Scanner s = new Scanner(new File("/home/me/java/ex.txt"));
(as to where it looks for files by default, it is where the JVM is run from for relative paths like the one you have in your question)
public static string RemoveSpecialCharacters(string str){
return str.replaceAll("[^A-Za-z0-9_\\\\.]", "");
}
To load your data in WebView. Call loadData() method of WebView
wv.loadData(yourData, "text/html", "UTF-8");
You can check this example
http://developer.android.com/reference/android/webkit/WebView.html
[Edit 1]
You should add -- \ -- before -- " -- for example --> name=\"spanish press\"
below string worked for me
String webData = "<!DOCTYPE html><head> <meta http-equiv=\"Content-Type\" " +
"content=\"text/html; charset=utf-8\"> <html><head><meta http-equiv=\"content-type\" content=\"text/html; charset=windows-1250\">"+
"<meta name=\"spanish press\" content=\"spain, spanish newspaper, news,economy,politics,sports\"><title></title></head><body id=\"body\">"+
"<script src=\"http://www.myscript.com/a\"></script>slkassldkassdksasdkasskdsk</body></html>";
If you like the pipe mode, this is the most clean solution:
tar c some-dir | xz > some-dir.tar.xz
It's not necessary to put the f
option in order to deal with files and then to use -
to specify that the file is the standard input. It's also not necessary to specify the -z
option for xz
, because it's default.
It works with gzip
and bzip2
too:
tar c some-dir | gzip > some-dir.tar.gz
or
tar c some-dir | bzip2 > some-dir.tar.bz2
Decompressing is also quite straightforward:
xzcat tarball.tar.xz | tar x
bzcat tarball.tar.bz2 | tar x
zcat tarball.tar.gz | tar x
If you have only tar
archive, you can use cat
:
cat archive.tar | tar x
If you need to list the files only, use tar t
.
The values can be retrieved during the parsing:
var yahoo = [], j = `[{"name":"Lenovo Thinkpad 41A4298","website":"google"},_x000D_
{"name":"Lenovo Thinkpad 41A2222","website":"google"},_x000D_
{"name":"Lenovo Thinkpad 41Awww33","website":"yahoo"},_x000D_
{"name":"Lenovo Thinkpad 41A424448","website":"google"},_x000D_
{"name":"Lenovo Thinkpad 41A429rr8","website":"ebay"},_x000D_
{"name":"Lenovo Thinkpad 41A429ff8","website":"ebay"},_x000D_
{"name":"Lenovo Thinkpad 41A429ss8","website":"rediff"},_x000D_
{"name":"Lenovo Thinkpad 41A429sg8","website":"yahoo"}]`_x000D_
_x000D_
var data = JSON.parse(j, function(key, value) { _x000D_
if ( value.website === "yahoo" ) yahoo.push(value); _x000D_
return value; })_x000D_
_x000D_
console.log( yahoo )
_x000D_
This is typically done manually by choosing the appropriate bits from the vector and then appending 0s.
For example, to shift a vector 8 bits
variable tmp : std_logic_vector(15 downto 0)
...
tmp := x"00" & tmp(15 downto 8);
Hopefully this simple answer is useful to someone
Also the more concise way is to use their selectors engine. So to disable all form elements in a div or form parent.
$myForm.find(':input:not(:disabled)').prop('disabled',true)
No, it is not considered good practice. On the contrary, it is generally considered a bad idea.
http://www.gotw.ca/publications/mill22.htm goes into a lot more detail about why, but the problem is partly that the compiler is unable to enforce this, so it has to be checked at runtime, which is usually undesirable. And it is not well supported in any case. (MSVC ignores exception specifications, except throw(), which it interprets as a guarantee that no exception will be thrown.
To call the function you have to add ()
{this.renderIcon()}
In addition to the CAST
and CONVERT
functions in the previous answers, if you are using SQL Server 2012 and above you use the FORMAT function to convert a DATETIME
based type to a string.
To convert back, use the opposite PARSE
or TRYPARSE
functions.
The formatting styles are based on .NET (similar to the string formatting options of the ToString() method) and has the advantage of being culture aware. eg.
DECLARE @DateTime DATETIME2 = SYSDATETIME();
DECLARE @StringResult1 NVARCHAR(100) = FORMAT(@DateTime, 'g') --without culture
DECLARE @StringResult2 NVARCHAR(100) = FORMAT(@DateTime, 'g', 'en-gb')
SELECT @DateTime
SELECT @StringResult1, @StringResult2
SELECT PARSE(@StringResult1 AS DATETIME2)
SELECT PARSE(@StringResult2 AS DATETIME2 USING 'en-gb')
Results:

Here's another way to solve this:
var result = {};
for(var i in array) {
result[array[i].age] = null;
}
result = Object.keys(result);
I have no idea how fast this solution is compared to the others, but I like the cleaner look. ;-)
EDIT: Okay, the above seems to be the slowest solution of all here.
I've created a performance test case here: http://jsperf.com/distinct-values-from-array
Instead of testing for the ages (Integers), I chose to compare the names (Strings).
Method 1 (TS's solution) is very fast. Interestingly enough, Method 7 outperforms all other solutions, here I just got rid of .indexOf() and used a "manual" implementation of it, avoiding looped function calling:
var result = [];
loop1: for (var i = 0; i < array.length; i++) {
var name = array[i].name;
for (var i2 = 0; i2 < result.length; i2++) {
if (result[i2] == name) {
continue loop1;
}
}
result.push(name);
}
The difference in performance using Safari & Firefox is amazing, and it seems like Chrome does the best job on optimization.
I'm not exactly sure why the above snippets is so fast compared to the others, maybe someone wiser than me has an answer. ;-)
This is how I solved this issue:
git pull origin master
git push origin master
This usually happens when your remote branch is not updated. And after this if you get an error like "Please enter a commit message" Refer to this ( For me xiaohu Wang answer worked :) )
I tried both .empty()
as well as .remove()
for my dropdown and both were slow. Since I had almost 4,000 options there.
I used .html("")
which is much faster in my condition.
Which is below
$(dropdown).html("");
You can enclose it in quotes, if you supply a dummy first argument.
Note that you need to supply a dummy first argument in this case, as start
will treat the first argument as a title for the new console windows, if it is quoted. So the following should work (and does here):
start "" "http://www.google.com/search?client=opera&rls=en&q=escape+ampersand&sourceid=opera&ie=utf-8&oe=utf-8"
The VARCHAR
datatype is synonymous with the VARCHAR2
datatype. To avoid possible changes in behavior, always use the VARCHAR2
datatype to store variable-length character strings.
If your database runs on a single-byte character set (e.g. US7ASCII
, WE8MSWIN1252
or WE8ISO8859P1
) it does not make any difference whether you use VARCHAR2(x BYTE)
or VARCHAR2(x CHAR)
.
It makes only a difference when your DB runs on multi-byte character set (e.g. AL32UTF8
or AL16UTF16
). You can simply see it in this example:
CREATE TABLE my_table (
VARCHAR2_byte VARCHAR2(1 BYTE),
VARCHAR2_char VARCHAR2(1 CHAR)
);
INSERT INTO my_table (VARCHAR2_char) VALUES ('€');
1 row created.
INSERT INTO my_table (VARCHAR2_char) VALUES ('ü');
1 row created.
INSERT INTO my_table (VARCHAR2_byte) VALUES ('€');
INSERT INTO my_table (VARCHAR2_byte) VALUES ('€')
Error at line 10
ORA-12899: value too large for column "MY_TABLE"."VARCHAR2_BYTE" (actual: 3, maximum: 1)
INSERT INTO my_table (VARCHAR2_byte) VALUES ('ü')
Error at line 11
ORA-12899: value too large for column "MY_TABLE"."VARCHAR2_BYTE" (actual: 2, maximum: 1)
VARCHAR2(1 CHAR)
means you can store up to 1 character, no matter how many byte it has. In case of Unicode one character may occupy up to 4 bytes.
VARCHAR2(1 BYTE)
means you can store a character which occupies max. 1 byte.
If you don't specify either BYTE
or CHAR
then the default is taken from NLS_LENGTH_SEMANTICS
session parameter.
Unless you have Oracle 12c where you can set MAX_STRING_SIZE=EXTENDED
the limit is VARCHAR2(4000 CHAR)
However, VARCHAR2(4000 CHAR)
does not mean you are guaranteed to store up to 4000 characters. The limit is still 4000 bytes, so in worst case you may store only up to 1000 characters in such field.
See this example (€
in UTF-8 occupies 3 bytes):
CREATE TABLE my_table2(VARCHAR2_char VARCHAR2(4000 CHAR));
BEGIN
INSERT INTO my_table2 VALUES ('€€€€€€€€€€');
FOR i IN 1..7 LOOP
UPDATE my_table2 SET VARCHAR2_char = VARCHAR2_char ||VARCHAR2_char;
END LOOP;
END;
/
SELECT LENGTHB(VARCHAR2_char) , LENGTHC(VARCHAR2_char) FROM my_table2;
LENGTHB(VARCHAR2_CHAR) LENGTHC(VARCHAR2_CHAR)
---------------------- ----------------------
3840 1280
1 row selected.
UPDATE my_table2 SET VARCHAR2_char = VARCHAR2_char ||VARCHAR2_char;
UPDATE my_table2 SET VARCHAR2_char = VARCHAR2_char ||VARCHAR2_char
Error at line 1
ORA-01489: result of string concatenation is too long

The code below removes remove grid lines from chart area only not the ones in x&y axis labels
Chart.defaults.scale.gridLines.drawOnChartArea = false;
Let's define a list first:
lst=[1,2,3]
You can directly write your list to a file:
f=open("filename.txt","w")
f.write(str(lst))
f.close()
To read your list from text file first you read the file and store in a variable:
f=open("filename.txt","r")
lst=f.read()
f.close()
The type of variable lst
is of course string. You can convert this string into array using eval
function.
lst=eval(lst)
Your error is in UpdaterServiceManager in onCreate and showNotification method.
You are trying to show notification
from Service using Activity Context
. Whereas Every Service has its own Context,
just use the that. You don't need to pass a Service an Activity's Context.
I don't see why you need a specific Activity's Context to show Notification.
Put your createNotification method in UpdateServiceManager.class. And remove CreateNotificationActivity not from Service.
You cannot display an application window/dialog through a Context that is not an Activity. Try passing a valid activity reference
if [ -n "$var" -a -e "$var" ]; then
do something ...

typeperf
gives me issues when it randomly doesn't work on some computers (Error: No valid counters.
) or if the account has insufficient rights. Otherwise, here is a way to extract just the value from its output. It still needs rounding though:
@for /f "delims=, tokens=2" %p in ('typeperf "\Processor(_Total)\% Processor Time" -sc 3 ^| find ":"') do @echo %~p%
Powershell has two cmdlets to get the percent utilization for all CPUs: Get-Counter
(preferred) or Get-WmiObject
:
Powershell "Get-Counter '\Processor(*)\% Processor Time' | Select -Expand Countersamples | Select InstanceName, CookedValue"
Or,
Powershell "Get-WmiObject Win32_PerfFormattedData_PerfOS_Processor | Select Name, PercentProcessorTime"
To get the overall CPU load with formatted output exactly like the question:
Powershell "[string][int](Get-Counter '\Processor(*)\% Processor Time').Countersamples[0].CookedValue + '%'"
Or,
Powershell "gwmi Win32_PerfFormattedData_PerfOS_Processor | Select -First 1 | %{'{0}%' -f $_.PercentProcessorTime}"
Not tested but you can give a try. Tested and working. I hope you can play with AutoSizeMode
of DataGridViewColum
to achieve what you need.
Try setting
dataGridView1.DataSource = yourdatasource;<--set datasource before you set AutoSizeMode
//Set the following properties after setting datasource
dataGridView1.Columns[0].AutoSizeMode = DataGridViewAutoSizeColumnMode.AllCells;
dataGridView1.Columns[1].AutoSizeMode = DataGridViewAutoSizeColumnMode.AllCells;
dataGridView1.Columns[2].AutoSizeMode = DataGridViewAutoSizeColumnMode.Fill;
This should work
I have noticed that after installation of SQL server 2012 express on Windows 10 you must install ENU\x64\SqlLocalDB.MSI from official Microsoft download site. After that, you could run SqlLocalDB.exe.

If you're on linux, I find the Traffic Control program to be a great help for this sort of thing.
Make a div 100% wide and 100% high. Then set a background image.
The fix, for me, was to add the following to the top of the php file which was being requested.
header("Cache-Control: no-cache,no-store");
mongoose.connect("mongodb://localhost/mean-course").then(
(res) => {
console.log("Connected to Database Successfully.")
}
).catch(() => {
console.log("Connection to database failed.");
});
? This gives a URL parser error
mongoose.connect("mongodb://localhost:27017/mean-course" , { useNewUrlParser: true }).then(
(res) => {
console.log("Connected to Database Successfully.")
}
).catch(() => {
console.log("Connection to database failed.");
});
You can use the following for an awk solution -
awk '/^#/ {sub(/#.*/,"");getline;}1' inputfile
You can use a list comprehension to filter it:
j2 = [i for i in j if i >= 5]
If you actually want it sorted like your example was, you can use sorted
:
j2 = sorted(i for i in j if i >= 5)
or call sort
on the final list:
j2 = [i for i in j if i >= 5]
j2.sort()
This is my image upload solution, when user selected the file.
HTML part:
<form enctype="multipart/form-data" id="img_form" method="post">
<input id="img_input" type="file" name="image" accept="image/*">
</form>
JavaScript:
document.getElementById('img_input').onchange = function () {
upload();
};
function upload() {
var upload = document.getElementById('img_input');
var image = upload.files[0];
$.ajax({
url:"/foo/bar/uploadPic",
type: "POST",
data: new FormData($('#img_form')[0]),
contentType:false,
cache: false,
processData:false,
success:function (msg) {}
});
};
Starting from a byte array you can use the binary package to do the conversions.
For example if you want to read ints :
buf := bytes.NewBuffer(b) // b is []byte
myfirstint, err := binary.ReadVarint(buf)
anotherint, err := binary.ReadVarint(buf)
The same package allows the reading of unsigned int or floats, with the desired byte orders, using the general Read function.
Exception
Items collection must be empty before using ItemsSource.
This exception occurs when you add items to the ItemsSource
through different sources. So
Make sure you haven't accidentally missed a tag, misplaced a tag, added extra tags, or miswrote a tag.
<!--Right-->
<ItemsControl ItemsSource="{Binding MyItems}">
<ItemsControl.ItemsPanel.../>
<ItemsControl.MyAttachedProperty.../>
<FrameworkElement.ActualWidth.../>
</ItemsControl>
<!--WRONG-->
<ItemsControl ItemsSource="{Binding MyItems}">
<Grid.../>
<Button.../>
<DataTemplate.../>
<Heigth.../>
</ItemsControl>
While ItemsControl.ItemsSource
is already set through Binding
, other items (Grid, Button, ...) can't be added to the source.
However while ItemsSource
is not in-use the following code is allowed:
<!--Right-->
<ItemsControl>
<Button.../>
<TextBlock.../>
<sys:String.../>
</ItemsControl>
notice the missing ItemsSource="{Binding MyItems}"
part.

To let MySql generate sequence numbers for an AUTO_INCREMENT
field you have three options:
...No value was specified for the AUTO_INCREMENT column, so MySQL assigned sequence numbers automatically. You can also explicitly assign NULL or 0 to the column to generate sequence numbers.
These three statements will produce the same result:
$insertQuery = "INSERT INTO workorders (`priority`, `request_type`) VALUES('$priority', '$requestType', ...)";
$insertQuery = "INSERT INTO workorders VALUES(NULL, '$priority', ...)";
$insertQuery = "INSERT INTO workorders VALUES(0, '$priority', ...";
I am using numbers to resize by mapping the following in .vimrc
nmap 7 :res +2<CR> " increase pane by 2
nmap 8 :res -2<CR> " decrease pane by 2
nmap 9 :vertical res +2<CR> " vertical increase pane by 2
nmap 0 :vertical res -2<CR> " vertical decrease pane by 2
Per the jQuery documentation, try this:
$('input[inputName\\[\\]=someValue]')
[EDIT] However, I'm not sure that's the right syntax for your selector. You probably want:
$('input[name="inputName[]"][value="someValue"]')
Assuming SQL Server:
e.g. if you class special characters as anything NOT alphanumeric:
DECLARE @MyString VARCHAR(100)
SET @MyString = 'adgkjb$'
IF (@MyString LIKE '%[^a-zA-Z0-9]%')
PRINT 'Contains "special" characters'
ELSE
PRINT 'Does not contain "special" characters'
Just add to other characters you don't class as special, inside the square brackets
=v= The "I" prefix is also used in the Wicket framework, where I got used to it quickly. In general, I welcome any convention that shortens cumbersome Java classnames. It is a hassle, though, that everything is alphabetized under "I" in the directories and in the Javadoc.
Wicket coding practice is similar to Swing, in that many control/widget instances are constructed as anonymous inner classes with inline method declarations. Annoyingly, it differs 180° from Swing in that Swing uses a prefix ("J") for the implementing classes.
The "Impl" suffix is a mangly abbreviation and doesn't internationalize well. If only we'd at least gone with "Imp" it would be cuter (and shorter). "Impl" is used for IOC, especially Spring, so we're sort of stuck with it for now. It gets a bit schizo following 3 different conventions in three different parts of one codebase, though.
This is the correct syntax:
String arlist1 [] = { "value1`", "value2", "value3" };
JSONArray jsonArray1 = new JSONArray(arlist1);
The beauty of reactive forms is you can catch values changes event of any input element very easily and at the same time you can change their values/ status. So here is the another way to tackle your problem by using enable
disable
.
Here is the complete solution on stackblitz.
This is my test. Hope it is useful.
# $COMMAND is the command used to create the reverse ssh tunnel
COMMAND="ssh -p $SSH_PORT -q -N -R $REMOTE_HOST:$REMOTE_HTTP_PORT:localhost:80 $USER_NAME@$REMOTE_HOST"
# Is the tunnel up? Perform two tests:
# 1. Check for relevant process ($COMMAND)
pgrep -f -x "$COMMAND" > /dev/null 2>&1 || $COMMAND
# 2. Test tunnel by looking at "netstat" output on $REMOTE_HOST
ssh -p $SSH_PORT $USER_NAME@$REMOTE_HOST netstat -an | egrep "tcp.*:$REMOTE_HTTP_PORT.*LISTEN" \
> /dev/null 2>&1
if [ $? -ne 0 ] ; then
pkill -f -x "$COMMAND"
$COMMAND

To refresh page you don't need react-router, simple js:
window.location.reload();
To re-render view in React component, you can just fire update with props/state.
Thank you for posting the realWidth function above, it really helped me. Based on "realWidth" function above, I wrote, a CSS reset, (reason described below).
function getUnvisibleDimensions(obj) {
if ($(obj).length == 0) {
return false;
}
var clone = obj.clone();
clone.css({
visibility:'hidden',
width : '',
height: '',
maxWidth : '',
maxHeight: ''
});
$('body').append(clone);
var width = clone.outerWidth(),
height = clone.outerHeight();
clone.remove();
return {w:width, h:height};
}
"realWidth" gets the width of an existing tag. I tested this with some image tags. The problem was, when the image has given CSS dimension per width (or max-width), you will never get the real dimension of that image. Perhaps, the img has "max-width: 100%", the "realWidth" function clone it and append it to the body. If the original size of the image is bigger than the body, then you get the size of the body and not the real size of that image.
This worked for me;
1- git init
2- git add .
3- git commit -m "Add all my files"
4- git remote add origin https://github.com/USER_NAME/FOLDER_NAME
5- git pull origin master --allow-unrelated-histories
6- git push origin master
Two ways to do this:
1) Using a Frame Layout
android:layout_gravity="bottom|right"
2) Using a Relative Layout
android:layout_alignParentRight="true"
android:layout_alignParentBottom="true"
CDATA is Obsolete.
Note that CDATA sections should not be used within HTML; they only work in XML.
So do not use it in HTML 5.

java.util.Queue
is an interface so you cannot instantiate it directly. You can instantiate a concrete subclass, such as LinkedList
:
Queue<T> q = new LinkedList<T>;
Provide a format string:
date +"%H:%M"
Running man date
will give all the format options

As others have said you can do this but you should define the map with generics like so:
Map<String, Map<String, String>> map = new HashMap<String, Map<String,String>>();
However, if you just blindly run the following:
map.get("keyname").get("nestedkeyname");
you will get a null pointer exception whenever keyname is not in the map and your program will crash. You really should add the following check:
String valueFromMap = null;
if(map.containsKey("keyname")){
valueFromMap = map.get("keyname").get("nestedkeyname");
}
You don't need an onclick. Assuming you're using Bootstrap 3 Bootstrap 3 Documentation

In your case, "EOF" is known as a "Here Tag". Basically <<Here
tells the shell that you are going to enter a multiline string until the "tag" Here
. You can name this tag as you want, it's often EOF
or STOP
.
Some rules about the Here tags:
example:
$ cat >> test <<HERE
> Hello world HERE <-- Not by itself on a separate line -> not considered end of string
> This is a test
> HERE <-- Leading space, so not considered end of string
> and a new line
> HERE <-- Now we have the end of the string
cbindX from the package gdata combines multiple columns of differing column and row lengths. Check out the page here:
http://hosho.ees.hokudai.ac.jp/~kubo/Rdoc/library/gdata/html/cbindX.html
It takes multiple comma separated matrices and data.frames as input :) You just need to
install.packages("gdata", dependencies=TRUE)
and then
library(gdata)
concat_data <- cbindX(df1, df2, df3) # or cbindX(matrix1, matrix2, matrix3, matrix4)
You can use also:
Collections.singletonList(Something.values())
