That's because your dat1
and dat2
variables are just strings.
You should parse them to get a Date
object, for that format I always use the following function:
// parse a date in yyyy-mm-dd format
function parseDate(input) {
var parts = input.match(/(\d+)/g);
// new Date(year, month [, date [, hours[, minutes[, seconds[, ms]]]]])
return new Date(parts[0], parts[1]-1, parts[2]); // months are 0-based
}
I use this function because the Date.parse(string)
(or new Date(string)
) method is implementation dependent, and the yyyy-MM-dd format will work on modern browser but not on IE, so I prefer doing it manually.
Annoyingly Javascript's date.getSeconds()
et al will not pad the result with zeros 11:0:0
instead of 11:00:00
.
So I like to use
date.toLocaleTimestring()
Which renders 11:00:00 AM
. Just beware when using the extra options, some browsers don't support them (Safari)
an additional note:
if you have already added a remote ($git remote add origin ... ) and need to change that particular remote then do a remote remove first ($ git remote rm origin), before re-adding the new and improved repo URL (where "origin" was the name for the remote repo).
so to use the original example :
$ git remote add origin https://github.com/WEMP/project-slideshow.git
$ git remote rm origin
$ git remote add origin https://[email protected]/WEMP/project-slideshow.git
A key difference between __getattr__
and __getattribute__
is that __getattr__
is only invoked if the attribute wasn't found the usual ways. It's good for implementing a fallback for missing attributes, and is probably the one of two you want.
__getattribute__
is invoked before looking at the actual attributes on the object, and so can be tricky to implement correctly. You can end up in infinite recursions very easily.
New-style classes derive from object
, old-style classes are those in Python 2.x with no explicit base class. But the distinction between old-style and new-style classes is not the important one when choosing between __getattr__
and __getattribute__
.
You almost certainly want __getattr__
.
What I do is have a static class with the following code in my project:
#region Dataset -> Immediate Window
public static void printTbl(DataSet myDataset)
{
printTbl(myDataset.Tables[0]);
}
public static void printTbl(DataTable mytable)
{
for (int i = 0; i < mytable.Columns.Count; i++)
{
Debug.Write(mytable.Columns[i].ToString() + " | ");
}
Debug.Write(Environment.NewLine + "=======" + Environment.NewLine);
for (int rrr = 0; rrr < mytable.Rows.Count; rrr++)
{
for (int ccc = 0; ccc < mytable.Columns.Count; ccc++)
{
Debug.Write(mytable.Rows[rrr][ccc] + " | ");
}
Debug.Write(Environment.NewLine);
}
}
public static void ResponsePrintTbl(DataTable mytable)
{
for (int i = 0; i < mytable.Columns.Count; i++)
{
HttpContext.Current.Response.Write(mytable.Columns[i].ToString() + " | ");
}
HttpContext.Current.Response.Write("<BR>" + "=======" + "<BR>");
for (int rrr = 0; rrr < mytable.Rows.Count; rrr++)
{
for (int ccc = 0; ccc < mytable.Columns.Count; ccc++)
{
HttpContext.Current.Response.Write(mytable.Rows[rrr][ccc] + " | ");
}
HttpContext.Current.Response.Write("<BR>");
}
}
public static void printTblRow(DataSet myDataset, int RowNum)
{
printTblRow(myDataset.Tables[0], RowNum);
}
public static void printTblRow(DataTable mytable, int RowNum)
{
for (int ccc = 0; ccc < mytable.Columns.Count; ccc++)
{
Debug.Write(mytable.Columns[ccc].ToString() + " : ");
Debug.Write(mytable.Rows[RowNum][ccc]);
Debug.Write(Environment.NewLine);
}
}
#endregion
I then I will call one of the above functions in the immediate window and the results will appear there as well. For example if I want to see the contents of a variable 'myDataset' I will call printTbl(myDataset). After hitting enter, the results will be printed to the immediate window
in Swift 5
For those who don't want to use colored background to beat the selected state
Simply you can beat the problem by using #Selector & if statement to change the UIButton colors for each state individually easily
For Example:
override func viewDidLoad() {
super.viewDidLoad()
self.myButtonOutlet.backgroundColor = UIColor.white //to reset the button color to its original color ( optionally )
}
@IBOutlet weak var myButtonOutlet: UIButton!{
didSet{ // Button selector and image here
self.myButtonOutlet.setImage(UIImage(systemName: ""), for: UIControl.State.normal)
self.myButtonOutlet.setImage(UIImage(systemName: "checkmark"), for: UIControl.State.selected)
self.myButtonOutlet.addTarget(self, action: #selector(tappedButton), for: UIControl.Event.touchUpInside)
}
}
@objc func tappedButton() { // Colors selection is here
if self.myButtonOutlet.isSelected == true {
self.myButtonOutlet.isSelected = false
self.myButtonOutlet.backgroundColor = UIColor.white
} else {
self.myButtonOutlet.isSelected = true
self.myButtonOutlet.backgroundColor = UIColor.black
self.myButtonOutlet.tintColor00 = UIColor.white
}
}
It is not possible to assign values to an array all at once after initialization. The best alternative would be to use a loop.
for(i=0;i<N;i++)
{
array[i] = i;
}
You can hard code and assign values like --array[0] = 1
and so on.
Memcpy can also be used if you have the data stored in an array already.
Good answers so far, I want to only add that you could check the type of a node using nodeType
:
yourElement.nodeType
This will give you an integer: (taken from here)
| Value | Constant | Description | |
|-------|----------------------------------|---------------------------------------------------------------|--|
| 1 | Node.ELEMENT_NODE | An Element node such as <p> or <div>. | |
| 2 | Node.ATTRIBUTE_NODE | An Attribute of an Element. The element attributes | |
| | | are no longer implementing the Node interface in | |
| | | DOM4 specification. | |
| 3 | Node.TEXT_NODE | The actual Text of Element or Attr. | |
| 4 | Node.CDATA_SECTION_NODE | A CDATASection. | |
| 5 | Node.ENTITY_REFERENCE_NODE | An XML Entity Reference node. Removed in DOM4 specification. | |
| 6 | Node.ENTITY_NODE | An XML <!ENTITY ...> node. Removed in DOM4 specification. | |
| 7 | Node.PROCESSING_INSTRUCTION_NODE | A ProcessingInstruction of an XML document | |
| | | such as <?xml-stylesheet ... ?> declaration. | |
| 8 | Node.COMMENT_NODE | A Comment node. | |
| 9 | Node.DOCUMENT_NODE | A Document node. | |
| 10 | Node.DOCUMENT_TYPE_NODE | A DocumentType node e.g. <!DOCTYPE html> for HTML5 documents. | |
| 11 | Node.DOCUMENT_FRAGMENT_NODE | A DocumentFragment node. | |
| 12 | Node.NOTATION_NODE | An XML <!NOTATION ...> node. Removed in DOM4 specification. | |
Note that according to Mozilla:
The following constants have been deprecated and should not be used anymore: Node.ATTRIBUTE_NODE, Node.ENTITY_REFERENCE_NODE, Node.ENTITY_NODE, Node.NOTATION_NODE
This seems to work as well

In Ubuntu eclipse -clean -refresh
worked for me for Eclipse 3.8.1
Today, 2020 year, I've solved this problem with Xcode 11.7, Xcode 12.0 and Xcode 12.1 following these steps:
If it's messed up then the "When using this certificate" is set to "Always Trust" along with the blue +
Problem should have gone away. If that didn't work then go back to Keychain and just double check and see if there are any other Apple certificates that are set to Always Trust and repeat the process.
The name of the hook script is not so scary if you manage decipher it: it's pre revision property change hook. In short, the purpose of pre-revprop-change
hook script is to control changes of unversioned (revision) properties and to send notifications (e.g. to send an email when revision property is changed).
There are 2 types of properties in Subversion:
svn:needs-lock
and svn:mime-type
) that can be set on files and directories,svn:log
and svn:date
) that are set on repository revisions.Versioned properties have history and can be manipulated by ordinary users who have Read / Write access to a repository. On the other hand, unversioned properties do not have any history and serve mostly maintenance purpose. For example, if you commit a revision it immediately gets svn:date
with UTC time of your commit, svn:author
with your username and svn:log
with your commit log message (if you specified any).
As I already specified, the purpose of pre-revprop-change
hook script is to control changes of revision properties. You don't want everyone who has access to a repository to be able to modify all revision properties, so changing revision properties is forbidden by default. To allow users to change properties, you have to create pre-revprop-change
hook.
The simplest hook can contain just one line: exit 0
. It will allow any authenticated user to change any revision property and it should not be used in real environment. On Windows, you can use batch script or PowerShell-based script to implement some logic within pre-revprop-change
hook.
This PowerShell script allows to change svn:log
property only and denies empty log messages.
# Store hook arguments into variables with mnemonic names
$repos = $args[0]
$rev = $args[1]
$user = $args[2]
$propname = $args[3]
$action = $args[4]
# Only allow changes to svn:log. The author, date and other revision
# properties cannot be changed
if ($propname -ne "svn:log")
{
[Console]::Error.WriteLine("Only changes to 'svn:log' revision properties are allowed.")
exit 1
}
# Only allow modifications to svn:log (no addition/overwrite or deletion)
if ($action -ne "M")
{
[Console]::Error.WriteLine("Only modifications to 'svn:log' revision properties are allowed.")
exit 2
}
# Read from the standard input while the first non-white-space characters
$datalines = ($input | where {$_.trim() -ne ""})
if ($datalines.length -lt 25)
{
# Log message is empty. Show the error.
[Console]::Error.WriteLine("Empty 'svn:log' properties are not allowed.")
exit 3
}
exit 0
This batch script allows only "svnmgr" user to change revision properties:
IF "%3" == "svnmgr" (goto :label1) else (echo "Only the svnmgr user may change revision properties" >&2 )
exit 1
goto :eof
:label1
exit 0
I take it you can modify MyScript.ps1
. Then try to change it like so:
$(
Here is your current script
) *>&1 > output.txt
I just tried this with PowerShell 3. You can use all the redirect options as in Nathan Hartley's answer.
You can also do this.
//find the index of the CompanyName column
int columnIndex = thisReader.GetOrdinal("CompanyName");
//Get the value of the column. Will throw if the value is null.
string companyName = thisReader.GetString(columnIndex);
@missingfaktor 's answer is indeed correct but a bit over-complicated. Code is more verbose (at least for continuous intervals) then it could be, and requires overloads/casts and/or parameterization for long, float, Integer etc
if (num < 1)
System.Out.Println("invalid case: " + num); // you should verify that anyway
else if (num <= 5)
System.Out.Println("1 to 5");
else if (num <= 10)
System.Out.Println("6 to 10");
else if (num <= 42)
System.Out.Println("11 to 42");
else
System.Out.Println("43 to +infinity");

If you can base-64 encode your bytes, you could try using the result as your image source. In your model you might add something like:
public string ImageSource
{
get
{
string mimeType = /* Get mime type somehow (e.g. "image/png") */;
string base64 = Convert.ToBase64String(yourImageBytes);
return string.Format("data:{0};base64,{1}", mimeType, base64);
}
}
And in your view:
<img ... src="@Model.ImageSource" />
Here's a simple, pure-Python implementation. It should be used when performance is not critical (included for future Googlers).
import string
allowed = set(string.ascii_lowercase + string.digits + '.')
def check(test_str):
set(test_str) <= allowed
Regarding performance, iteration will probably be the fastest method. Regexes have to iterate through a state machine, and the set equality solution has to build a temporary set. However, the difference is unlikely to matter much. If performance of this function is very important, write it as a C extension module with a switch statement (which will be compiled to a jump table).
Here's a C implementation, which uses if statements due to space constraints. If you absolutely need the tiny bit of extra speed, write out the switch-case. In my tests, it performs very well (2 seconds vs 9 seconds in benchmarks against the regex).
#define PY_SSIZE_T_CLEAN
#include <Python.h>
static PyObject *check(PyObject *self, PyObject *args)
{
const char *s;
Py_ssize_t count, ii;
char c;
if (0 == PyArg_ParseTuple (args, "s#", &s, &count)) {
return NULL;
}
for (ii = 0; ii < count; ii++) {
c = s[ii];
if ((c < '0' && c != '.') || c > 'z') {
Py_RETURN_FALSE;
}
if (c > '9' && c < 'a') {
Py_RETURN_FALSE;
}
}
Py_RETURN_TRUE;
}
PyDoc_STRVAR (DOC, "Fast stringcheck");
static PyMethodDef PROCEDURES[] = {
{"check", (PyCFunction) (check), METH_VARARGS, NULL},
{NULL, NULL}
};
PyMODINIT_FUNC
initstringcheck (void) {
Py_InitModule3 ("stringcheck", PROCEDURES, DOC);
}
Include it in your setup.py:
from distutils.core import setup, Extension
ext_modules = [
Extension ('stringcheck', ['stringcheck.c']),
],
Use as:
>>> from stringcheck import check
>>> check("abc")
True
>>> check("ABC")
False
This is more an add-on to the best answer above (GZip Compression can be enabled directly through IIS) which is correct if your running IIS on Windows desktop however...
If your running IIS on Windows Server, this content compression feature is found in a different place to desktop Windows (not in programs and features in Control Panel). First open "Server Manager" then click Manage -> "Add Roles & Features" then keep clicking NEXT (make sure you select the correct server when you see the list of servers if your managing multiple servers from this instance) until you get to SERVER ROLES, scroll down to and open "Web Server (IIS)..." then "Web Server" then "Performance" then tick "Dynamic Content Compression" then click INSTALL. I tested this on Server 2016 Standard so there may be slight differences if your on an earlier version of Server.
Then follow the instructions from Testing - Check if GZIP Compression is Enabled
The other answers are correct, but if you are trying to make a list of functions, each with a different parameter, that can be executed later, the following code will do that:
import functools
a = [functools.partial(lambda x: x*x, x) for x in range(10)]
b = []
for i in a:
b.append(i())
In [26]: b
Out[26]: [0, 1, 4, 9, 16, 25, 36, 49, 64, 81]
While the example is contrived, I found it useful when I wanted a list of functions that each print something different, i.e.
import functools
a = [functools.partial(lambda x: print(x), x) for x in range(10)]
for i in a:
i()
Marshal.Copy works but is rather slow. Faster is to copy the bytes in a for loop. Even faster is to cast the byte array to a ulong array, copy as much ulong as fits in the byte array, then copy the possible remaining 7 bytes (the trail that is not 8 bytes aligned). Fastest is to pin the byte array in a fixed statement as proposed above in Tyalis' answer.
It seems the docs/tool have been updated and you can now add the image
tag to your script. This was successful for me.
Example:
version: '2'
services:
baggins.api.rest:
image: my.image.name:rc2
build:
context: ../..
dockerfile: app/Docker/Dockerfile.release
ports:
...
There are multiple ways you can remove/filter the null values from a column in DataFrame.
Lets create a simple DataFrame with below code:
date = ['2016-03-27','2016-03-28','2016-03-29', None, '2016-03-30','2016-03-31']
df = spark.createDataFrame(date, StringType())
Now you can try one of the below approach to filter out the null values.
# Approach - 1
df.filter("value is not null").show()
# Approach - 2
df.filter(col("value").isNotNull()).show()
# Approach - 3
df.filter(df["value"].isNotNull()).show()
# Approach - 4
df.filter(df.value.isNotNull()).show()
# Approach - 5
df.na.drop(subset=["value"]).show()
# Approach - 6
df.dropna(subset=["value"]).show()
# Note: You can also use where function instead of a filter.
You can also check the section "Working with NULL Values" on my blog for more information.
I hope it helps.
I just ran a page of side by sides comparisons and unless something has changed recently, I could see no better downsizing (scaling) using canvas vs. simple css. I tested in FF6 Mac OSX 10.7. Still slightly soft vs. the original.
I did however stumble upon something that did make a huge difference and that was using image filters in browsers that support canvas. You can actually manipulate images much like you can in Photoshop with blur, sharpen, saturation, ripple, grayscale, etc.
I then found an awesome jQuery plug-in which makes application of these filters a snap: http://codecanyon.net/item/jsmanipulate-jquery-image-manipulation-plugin/428234
I simply apply the sharpen filter right after resizing the image which should give you the desired effect. I didn't even have to use a canvas element.
I would also like to recommend vscode extension Peep, which allows you to toggle hide on the excluded files in your projects settings.json.
Hit F1 for vscode command line (command palette), then
ext install [enter] peep [enter]
You can bind "extension.peepToggle" to a key like Ctrl+Shift+P (same as F1 by default) for easy toggling. Hit Ctrl+K Ctrl+S for key bindings, enter peep
, select Peep Toggle and add your binding.
Try the freeware iOS Console. Just download, launch, connect your device -- et voila!

I am very much thankful to Darin Rousseau for helping me.
I use the free file searching program Everything, search for *.sql files across my C: drive, and then sort by Last Modified, and then browse by the date I think it was probably last executed.
It usually brings up loads of autorecovery files from a variety of locations. And you don't have to worry where the latest version of SSMS/VS is saving the backup files this version.
Inspired by DanSalmo's comment, here is a solution that is concise, elegant, and at the same time is one of the fastest solutions.
good, bad = [], []
for item in my_list:
good.append(item) if item in set(goodvals) else bad.append(item)
Tip: Turning goodval
into a set gives us an easy 40% speed boost.
If you have the need for maximum speed, we take the fastest answer and turbocharge it by turning good_list into a set. That gives us a 45% speed boost, and we end up with a solution that is more than 5.5x as fast as the slowest solution, even while it remains readable.
good_list_set = set(good_list) # 45% faster than a tuple.
good, bad = [], []
for item in my_origin_list:
if item in good_list_set:
good.append(item)
else:
bad.append(item)
A little shorter:
good_list_set = set(good_list) # 45% faster than a tuple.
good, bad = [], []
for item in my_origin_list:
out = good if item in good_list_set else bad
out.append(item)
Elegance can be somewhat subjective, but some of the Rube Goldberg style solutions that are cute and ingenious are quite concerning and should not be used in production code in any language, let alone python which is elegant at heart.

This is in fact the best example ever for Image Zoom and Pan in android,

You can also use the element selectors:
mat-header-cell:nth-child(1), mat-cell:nth-child(1) {
flex: 0 0 64px;
}
But jymdman's answer is the most recommended way to go in most cases.
System.IO.StreamReader myFile =
new System.IO.StreamReader("c:\\test.txt");
string myString = myFile.ReadToEnd();
You just have to double up on the single quotes...
insert into Person (First, Last)
values ('Joe', 'O''Brien')
@Adrian's answer is perfectly suitable, I just wanted to share another way of achieving the same result:
select nvl(a.id, b.id)
from a full outer join b on a.id = b.id
order by b.id;
_MSC_VER

The version number above of course refers to the major version of your Visual studio you see in the about box, not to the year in the name. A thorough list can be found here. Starting recently, Visual Studio will start updating its ranges monotonically, meaning you should check ranges, rather than exact compiler values.
cl.exe /?
will give a hint of the used version, e.g.:

A trick I learned from this PR if you don't want to define it as a static final variable but want to save a bit of overhead and guarantee thread safe.
private static final ThreadLocal<ObjectMapper> om = new ThreadLocal<ObjectMapper>() {
@Override
protected ObjectMapper initialValue() {
ObjectMapper objectMapper = new ObjectMapper();
objectMapper.configure(DeserializationFeature.FAIL_ON_UNKNOWN_PROPERTIES, false);
return objectMapper;
}
};
public static ObjectMapper getObjectMapper() {
return om.get();
}

In this case, if you really want to use ReadToEnd
method in MemoryStream
in an easy way, you can use this Extension Method to achieve this:
public static class SetExtensions
{
public static string ReadToEnd(this MemoryStream BASE)
{
BASE.Position = 0;
StreamReader R = new StreamReader(BASE);
return R.ReadToEnd();
}
}
And you can use this method in this way:
using (MemoryStream m = new MemoryStream())
{
//for example i want to serialize an object into MemoryStream
//I want to use XmlSeralizer
XmlSerializer xs = new XmlSerializer(_yourVariable.GetType());
xs.Serialize(m, _yourVariable);
//the easy way to use ReadToEnd method in MemoryStream
MessageBox.Show(m.ReadToEnd());
}
Having run both queries on a SQL Server 2012 instance, I can confirm the first query was fastest in my case.
The query with the LIKE
keyword showed a clustered index scan.
The CONTAINS
also had a clustered index scan with additional operators for the full text match and a merge join.
It turns out that it was shrinking and growing correctly, providing the desired behaviour all along; except that in all current browsers flexbox wasn't accounting for the vertical scrollbar! Which is why the content appears to be getting cut off.
You can see here, which is the original code I was using before I added the fixed widths, that it looks like the column isn't growing to accomodate the text:
http://jsfiddle.net/2w157dyL/1/
However if you make the content in that column wider, you'll see that it always cuts it off by the same amount, which is the width of the scrollbar.
So the fix is very, very simple - add enough right padding to account for the scrollbar:
http://jsfiddle.net/2w157dyL/2/
main > section {_x000D_
overflow-y: auto;_x000D_
padding-right: 2em;_x000D_
}
_x000D_
It was when I was trying some things suggested by Michael_B (specifically adding a padding buffer) that I discovered this, thanks so much!
Edit: I see that he also posted a fiddle which does the same thing - again, thanks so much for all your help
This is a nice way to do it:
Double d = 0.5;
float f = d.floatValue();
if you have d as a primitive type just add one line:
double d = 0.5;
Double D = Double.valueOf(d);
float f = D.floatValue();
I hit this question looking for how to run batch scripts during user logon on a standalone windows server (workgroup not in domain). I found the answer in using group policy.
cmd /k mybatchfile.cmd
if you want the command window to stay (on desktop) after batch script have finished.Use the following code:
if(processing == success) {
header("Location:filename");
exit();
}
And you are good to go.
You can use the bindParam
or bindValue
methods to help prepare your statement.
It makes things more clear on first sight instead of doing $check->execute(array(':name' => $name));
Especially if you are binding multiple values/variables.
Check the clear, easy to read example below:
$q = $db->prepare("SELECT id FROM table WHERE forename = :forename and surname = :surname LIMIT 1");
$q->bindValue(':forename', 'Joe');
$q->bindValue(':surname', 'Bloggs');
$q->execute();
if ($q->rowCount() > 0){
$check = $q->fetch(PDO::FETCH_ASSOC);
$row_id = $check['id'];
// do something
}
If you are expecting multiple rows remove the LIMIT 1
and change the fetch method into fetchAll
:
$q = $db->prepare("SELECT id FROM table WHERE forename = :forename and surname = :surname");// removed limit 1
$q->bindValue(':forename', 'Joe');
$q->bindValue(':surname', 'Bloggs');
$q->execute();
if ($q->rowCount() > 0){
$check = $q->fetchAll(PDO::FETCH_ASSOC);
//$check will now hold an array of returned rows.
//let's say we need the second result, i.e. index of 1
$row_id = $check[1]['id'];
// do something
}
Go through http://nodejs.org/api/fs.html
One important thing - you can use sync functions also. (It will work like C program)
Unfortunately, threads do exist. A thread is something tangible. You can kill one, and the others will still be running. You can spawn new threads.... although each thread is not it's own process, they are running separately inside the process. On multi-core machines, 2 threads could run at the same time.

System.out.println(s.length());
Update for Xcode (Version 9.1). Please follow below steps for refreshing Provisioning profiles
Using Xcode Organizer
In short, you can navigate to MobileDevice/Provisioning Profiles/ folder path and delete all profiles and then Archive. Now you can see there are new profiles for you. Cheers :)
@JasonH hope it will help you.
There is restriction on using --jars
: if you want to specify a directory for location of jar/xml
file, it doesn't allow directory expansions. This means if you need to specify absolute path for each jar.
If you specify --driver-class-path
and you are executing in yarn cluster mode, then driver class doesn't get updated. We can verify if class path is updated or not under spark ui or spark history server under tab environment.
Option which worked for me to pass jars which contain directory expansions and which worked in yarn cluster mode was --conf
option. It's better to pass driver and executor class paths as --conf
, which adds them to spark session object itself and those paths are reflected on Spark Configuration. But Please make sure to put jars on the same path across the cluster.

J2EE traditionally referred to products and standards released by Sun. For example if you were developing a standard J2EE web application, you would be using EJBs, Java Server Faces, and running in an application server that supports the J2EE standard. However since there is such a huge open source plethora of libraries and products that do the same jobs as well as (and many will argue better) then these Sun offerings, the day to day meaning of J2EE has migrated into referring to these as well (For instance a Spring/Tomcat/Hibernate solution) in many minds.
This is a great book in my opinion that discusses the 'open source' approach to J2EE http://www.theserverside.com/tt/articles/article.tss?l=J2EEWithoutEJB_BookReview
Another alternative is to use DATE()
function on the left hand operand as shown below
SELECT users.* FROM users WHERE DATE(created_at) BETWEEN '2011-12-01' AND '2011-12-06'
May be it will helpful:
<Border BorderBrush="Black" BorderThickness="1" HorizontalAlignment="Left" Height="160" Margin="10,55,0,0" VerticalAlignment="Top" Width="492"/>
I am using TypeScript version 3.6
and I can do like this:
let templateStr = 'This is an {0} for {1} purpose';
const finalStr = templateStr.format('example', 'format'); // This is an example for format purpose
<%= f.submit nil, :class => 'btn btn-primary' %>
Yields something like:
It's possible that you're creating your controls on the wrong thread. Consider the following documentation from MSDN:
This means that InvokeRequired can return false if Invoke is not required (the call occurs on the same thread), or if the control was created on a different thread but the control's handle has not yet been created.
In the case where the control's handle has not yet been created, you should not simply call properties, methods, or events on the control. This might cause the control's handle to be created on the background thread, isolating the control on a thread without a message pump and making the application unstable.
You can protect against this case by also checking the value of IsHandleCreated when InvokeRequired returns false on a background thread. If the control handle has not yet been created, you must wait until it has been created before calling Invoke or BeginInvoke. Typically, this happens only if a background thread is created in the constructor of the primary form for the application (as in Application.Run(new MainForm()), before the form has been shown or Application.Run has been called.
Let's see what this means for you. (This would be easier to reason about if we saw your implementation of SafeInvoke also)
Assuming your implementation is identical to the referenced one with the exception of the check against IsHandleCreated, let's follow the logic:
public static void SafeInvoke(this Control uiElement, Action updater, bool forceSynchronous)
{
if (uiElement == null)
{
throw new ArgumentNullException("uiElement");
}
if (uiElement.InvokeRequired)
{
if (forceSynchronous)
{
uiElement.Invoke((Action)delegate { SafeInvoke(uiElement, updater, forceSynchronous); });
}
else
{
uiElement.BeginInvoke((Action)delegate { SafeInvoke(uiElement, updater, forceSynchronous); });
}
}
else
{
if (uiElement.IsDisposed)
{
throw new ObjectDisposedException("Control is already disposed.");
}
updater();
}
}
Consider the case where we're calling SafeInvoke
from the non-gui thread for a control whose handle has not been created.
uiElement
is not null, so we check uiElement.InvokeRequired
. Per the MSDN docs (bolded) InvokeRequired
will return false
because, even though it was created on a different thread, the handle hasn't been created! This sends us to the else
condition where we check IsDisposed
or immediately proceed to call the submitted action... from the background thread!
At this point, all bets are off re: that control because its handle has been created on a thread that doesn't have a message pump for it, as mentioned in the second paragraph. Perhaps this is the case you're encountering?
Try this
var theCheckboxes = $(".pricing-levels-3 input[type='checkbox']");
theCheckboxes.click(function()
{
if (theCheckboxes.filter(":checked").length > 3)
$(this).removeAttr("checked");
});
A query's projection can only have one instance of a given name. As your WHERE clause shows, you have several tables with a column called ID. Because you are selecting *
your projection will have several columns called ID. Or it would have were it not for the compiler hurling ORA-00918.
The solution is quite simple: you will have to expand the projection to explicitly select named columns. Then you can either leave out the duplicate columns, retaining just (say) COACHES.ID or use column aliases: coaches.id as COACHES_ID
.
Perhaps that strikes you as a lot of typing, but it is the only way. If it is any comfort, SELECT *
is regarded as bad practice in production code: explicitly named columns are much safer.
A simpler way to think about it, perhaps: when main returns, your process will not exit if there are non-daemon threads still running.
A bit of advice: Clean shutdown is easy to get wrong when threads and synchronization are involved - if you can avoid it, do so. Use daemon threads whenever possible.

The simple answer is to turn off async
. But that's the wrong thing to do. The correct answer is to re-think how you write the rest of your code.
Instead of writing this:
function functABC(){
$.ajax({
url: 'myPage.php',
data: {id: id},
success: function(data) {
return data;
}
});
}
function foo () {
var response = functABC();
some_result = bar(response);
// and other stuff and
return some_result;
}
You should write it like this:
function functABC(callback){
$.ajax({
url: 'myPage.php',
data: {id: id},
success: callback
});
}
function foo (callback) {
functABC(function(data){
var response = data;
some_result = bar(response);
// and other stuff and
callback(some_result);
})
}
That is, instead of returning result, pass in code of what needs to be done as callbacks. As I've shown, callbacks can be nested to as many levels as you have function calls.
A quick explanation of why I say it's wrong to turn off async:
Turning off async will freeze the browser while waiting for the ajax call. The user cannot click on anything, cannot scroll and in the worst case, if the user is low on memory, sometimes when the user drags the window off the screen and drags it in again he will see empty spaces because the browser is frozen and cannot redraw. For single threaded browsers like IE7 it's even worse: all websites freeze! Users who experience this may think you site is buggy. If you really don't want to do it asynchronously then just do your processing in the back end and refresh the whole page. It would at least feel not buggy.
This is possible due to type erasure. You will find that
List<TestA> x = new ArrayList<TestA>();
List<TestB> y = new ArrayList<TestB>();
x.getClass().equals(y.getClass()); // true
Internally both lists are of type List<Object>
. For that reason you can't cast one to the other - there is nothing to cast.
If your problem is only with function overloading (you need to check if 'parameters' parameter is 'parameters' and not 'callback'), i would recommend you don't bother about argument type and
use this approach. The idea is simple - use literal objects to combine your parameters:
function getData(id, opt){
var data = voodooMagic(id, opt.parameters);
if (opt.callback!=undefined)
opt.callback.call(data);
return data;
}
getData(5, {parameters: "1,2,3", callback:
function(){for (i=0;i<=1;i--)alert("FAIL!");}
});
If you want to show just numbers without characters, put this line of code inside your XML file android:inputType="number"
. The output:
If you want to show a number keyboard that also shows characters, put android:inputType="phone"
on your XML. The output (with characters):
And if you want to show a number keyboard that masks your input just like a password, put android:inputType="numberpassword"
. The output:
I'm really sorry if I only post the links of the screenshot, I want to do research on how to do really post images here but it might consume my time so here it is. I hope my post can help other people. Yes, my answer is duplicate with other answers posted here but to save other people's time that they might need to run their code before seeing the output, my post might save you some time.
Use Tkinter there are a ton of tutorials online for this. basically, you can create events. Here is a link to a great site! This makes it easy to capture clicks. Also, if you are trying to make a game, Tkinter also has a GUI. Although, I wouldn't recommend Python for games at all, it could be a fun experiment. Good Luck!
Maybe I'm missing something, but a lot of these answers seem overly complicated. You should be able to just set the columns within a single list:
Column to the front:
df = df[ ['Mid'] + [ col for col in df.columns if col != 'Mid' ] ]
Or if instead, you want to move it to the back:
df = df[ [ col for col in df.columns if col != 'Mid' ] + ['Mid'] ]
Or if you wanted to move more than one column:
cols_to_move = ['Mid', 'Zsore']
df = df[ cols_to_move + [ col for col in df.columns if col not in cols_to_move ] ]
I have this problem when update android studio from 3.2 to 3.3 and test every answers that i none of them was working. at the end i enabled Maven repository and its work.
If you want to stick to grep:
grep -A1 'blah' logfile | grep -v "blah"
or alternatively with sed:
sed -n '/blah/{n;p;}' logfile
ITNOA
You can use C++ function for doing this.
std::string repeat(const std::string& input, size_t num)
{
std::ostringstream os;
std::fill_n(std::ostream_iterator<std::string>(os), num, input);
return os.str();
}
For hosted repositories you can since svn version 1.7 use svnrdump
, which is analogous to svnadmin dump
for local repositories. This article provides a nice walk-through, which essentially boils down to:
svnrdump dump /URL/to/remote/repository > myRepository.dump
After you have downloaded the dump file you can import it locally
svnadmin load /path/to/local/repository < myRepository.dump
or upload it to the host of your choice.
I ended up with upstart, which works fine.
func replace(input: String, start: Int,lenght: Int, newChar: Character) -> String {
var chars = Array(input.characters)
for i in start...lenght {
guard i < input.characters.count else{

}
chars[i] = newChar
}
return String(chars)
}
I tried ComboBox1_KeyPress but it allows to delete the character & you can also use copy paste command. My DropDownStyle is set to DropDownList but still no use. So I did below step to avoid combobox text editing.
Below code handles delete & backspace key. And also disables combination with control key (e.g. ctr+C or ctr+X)
Private Sub CmbxInType_KeyDown(sender As Object, e As KeyEventArgs) Handles CmbxInType.KeyDown
If e.KeyCode = Keys.Delete Or e.KeyCode = Keys.Back Then
e.SuppressKeyPress = True
End If
If Not (e.Control AndAlso e.KeyCode = Keys.C) Then
e.SuppressKeyPress = True
End If
End Sub
In form load use below line to disable right click on combobox control to avoid cut/paste via mouse click.
CmbxInType.ContextMenu = new ContextMenu()
For displaying short, formatted text that doesn't need to be editable, Core Text is the way to go. There are several open-source projects for labels that use NSAttributedString
and Core Text for rendering. See CoreTextAttributedLabel or OHAttributedLabel for example.
Modern browsers have built-in javascript functions for Base64 encoding btoa() and decoding atob(). More info about support in older browser versions: https://caniuse.com/?search=atob
However, be aware that atob
and btoa
functions work only for ASCII charset.
If you need Base64 functions for UTF-8 charset, you can do it with:
function base64_encode(s) {
return btoa(unescape(encodeURIComponent(s)));
}
function base64_decode(s) {
return decodeURIComponent(escape(atob(s)));
}
$serverIP = $_SERVER["SERVER_ADDR"];
echo "Server IP is: <b>{$serverIP}</b>";
If you really want a vba solution you can loop through a range like this:
Sub Check()
Dim dat As Variant
Dim rng As Range
Dim i As Long
Set rng = Range("A1:A100")
dat = rng
For i = LBound(dat, 1) To UBound(dat, 1)
If dat(i, 1) <> "" Then
rng(i, 2).Value = "My Text"
End If
Next
End Sub
*EDIT*
Instead of using varients you can just loop through the range like this:
Sub Check()
Dim rng As Range
Dim i As Long
'Set the range in column A you want to loop through
Set rng = Range("A1:A100")
For Each cell In rng
'test if cell is empty
If cell.Value <> "" Then
'write to adjacent cell
cell.Offset(0, 1).Value = "My Text"
End If
Next
End Sub
This is due to the fact that cv2 uses the type "uint8" from numpy. Therefore, you should define the type when creating the array.
Something like the following:
import numpy
import cv2
b = numpy.zeros([5,5,3], dtype=numpy.uint8)
b[:,:,0] = numpy.ones([5,5])*64
b[:,:,1] = numpy.ones([5,5])*128
b[:,:,2] = numpy.ones([5,5])*192
Here's a more portable version (just for fun, it is not necessary in your case):
#!/usr/bin/env python
# -*- coding: utf-8 -*-
from subprocess import Popen, PIPE, STDOUT
try:
from subprocess import DEVNULL # py3k
except ImportError:
import os
DEVNULL = open(os.devnull, 'wb')
text = u"René Descartes"
p = Popen(['espeak', '-b', '1'], stdin=PIPE, stdout=DEVNULL, stderr=STDOUT)
p.communicate(text.encode('utf-8'))
assert p.returncode == 0 # use appropriate for your program error handling here
for i in ...:
for j in ...:
for k in ...:
if something:
# continue loop i
In a general case, when you have multiple levels of looping and break
does not work for you (because you want to continue one of the upper loops, not the one right above the current one), you can do one of the following
def inner():
for j in ...:
for k in ...:
if something:
return
for i in ...:
inner()
The disadvantage is that you may need to pass to that new function some variables, which were previously in scope. You can either just pass them as parameters, make them instance variables on an object (create a new object just for this function, if it makes sense), or global variables, singletons, whatever (ehm, ehm).
Or you can define inner
as a nested function and let it just capture what it needs (may be slower?)
for i in ...:
def inner():
for j in ...:
for k in ...:
if something:
return
inner()
Philosophically, this is what exceptions are for, breaking the program flow through the structured programming building blocks (if, for, while) when necessary.
The advantage is that you don't have to break the single piece of code into multiple parts. This is good if it is some kind of computation that you are designing while writing it in Python. Introducing abstractions at this early point may slow you down.
Bad thing with this approach is that interpreter/compiler authors usually assume that exceptions are exceptional and optimize for them accordingly.
class ContinueI(Exception):
pass
continue_i = ContinueI()
for i in ...:
try:
for j in ...:
for k in ...:
if something:
raise continue_i
except ContinueI:
continue
Create a special exception class for this, so that you don't risk accidentally silencing some other exception.
I am sure there are still other solutions.
I was also lost around getMeasuredWidth()
and getMeasuredHeight()
getHeight()
and getWidth()
for a long time.......... later i found onSizeChanged()
method to be REALLY helpful.
New Blog Post: how to get width and height dimensions of a customView (extends View) in Android http://syedrakibalhasan.blogspot.com/2011/02/how-to-get-width-and-height-dimensions.html
Like so:
//New Request
HttpLoggingInterceptor logging = new HttpLoggingInterceptor();
logging.setLevel(HttpLoggingInterceptor.Level.BASIC);
final OkHttpClient client = new OkHttpClient.Builder()
.addInterceptor(logging)
.connectTimeout(30, TimeUnit.SECONDS)
.readTimeout(30, TimeUnit.SECONDS)
.writeTimeout(30, TimeUnit.SECONDS)
.build();
SELECT *
FROM reservations
WHERE arrival >= '2012-01-01'
AND arrival < '2013-01-01'
;
BTW if the distribution of values indicates that an index scan will not be the worth (for example if all the values are in 2012), the optimiser could still choose a full table scan. YMMV. Explain is your friend.
It is very simple.. Here you go !!
import gzip
#path_to_file_to_be_extracted
ip = sample.gzip
#output file to be filled
op = open("output_file","w")
with gzip.open(ip,"rb") as ip_byte:
op.write(ip_byte.read().decode("utf-8")
wf.close()
Simple Solution:
JsonElement element = new JsonParser().parse(new InputStreamReader(inputStream));
JSONObject jsonObject = new JSONObject(element.getAsJsonObject().toString());
It is kind of a workaround but works like a charm. Just add <option value="" style="display: none"></option>
as a filler. Like in:
<select size="4" ng-model="feed.config" ng-options="template.value as template.name for template in feed.configs">
<option value="" style="display: none"></option>
</select>
Use CURRENT_TIMESTAMP (or GETDATE() on archaic versions of SQL Server).
If you could not set your application autostart you can try to paste this code to manifest
<requestedExecutionLevel level="asInvoker" uiAccess="false" />
or delete manifest I had found it in my application
I'll just comment you can get a lot of mileage out of table
when trying to "fake" a dictionary also, e.g.
> x <- c("a","a","b","b","b","c")
> (t <- table(x))
x
a b c
2 3 1
> names(t)
[1] "a" "b" "c"
> o <- order(as.numeric(t))
> names(t[o])
[1] "c" "a" "b"
etc.
Actually you can do it.
Although, someone should note that repeating the CASE
statements are not bad as it seems. SQL Server's query optimizer is smart enough to not execute the CASE
twice so that you won't get any performance hit because of that.
Additionally, someone might use the following logic to not repeat the CASE (if it suits you..)
INSERT INTO dbo.T1
(
Col1,
Col2,
Col3
)
SELECT
1,
SUBSTRING(MyCase.MergedColumns, 0, CHARINDEX('%', MyCase.MergedColumns)),
SUBSTRING(MyCase.MergedColumns, CHARINDEX('%', MyCase.MergedColumns) + 1, LEN(MyCase.MergedColumns) - CHARINDEX('%', MyCase.MergedColumns))
FROM
dbo.T1 t
LEFT OUTER JOIN
(
SELECT CASE WHEN 1 = 1 THEN '2%3' END MergedColumns
) AS MyCase ON 1 = 1
This will insert the values (1, 2, 3) for each record in the table T1
. This uses a delimiter '%'
to split the merged columns. You can write your own split function depending on your needs (e.g. for handling null records or using complex delimiter for varchar
fields etc.). But the main logic is that you should join the CASE
statement and select from the result set of the join with using a split logic.
There is another code that's works for me (jQuery).

use px for precise placement of graphical elements. use em for measurements having to do positioning and spacing around text elements like line-height etc. px is pixel accurate, em can change dynamically with the font in use
Some times you can get the Exception which is given below
Caused by: java.lang.IllegalStateException: You need to use a Theme.AppCompat theme (or descendant) with this activity.
So for resolving you can use simple solution
add theme of you activity in manifest as dialog for appCompact.
android:theme="@style/Theme.AppCompat.Dialog"
It can be helpful for somebody.
You can try some positioning tricks. You can put the input in a div with position: relative
and a fixed height, then on the input have position: absolute; left: 0; right: 0;
, and any padding you like.
My frustration in being unable to get a plugin for Notepad++ to work came from not realizing that the DLL for the plugin had to be installed directly in the C:\Program Files (x86)\Notepad++\plugins directory, and NOT into a subfolder below that, named for the plugin.
I was misled because every OTHER plugin that comes with the clean installation of Notepad++ IS installed in its own subfolder under \plugins.
\plugins
+ DSpellCheck
+ MIME Tools
+ Converter (etc.)
I tried that with the plugin I was attempting to install (autosave), and just couldn't get it to work. But then thanks to an answer from Steve Chambers above, I tried putting the DLL directly into the \plugins folder and PRESTO! It Works.
Hope this helps save someone else similar frustrations!
As simple as that. Ctrl+F10, then N, to Show or hide line numbers.

I use brew and the prefix was already set to be:
$ npm config get prefix
/Users/[user]/.node
I did notice that the bin and lib folder were owned by root, which prevented the usual non sudo install, so I re-owned them to the user
$ cd /Users/[user]/.node
$ chown -R [user]:[group] lib
$ chown -R [user]:[group] bin
Then I just added the path to my .bash_profile which is located at /Users/[user]
PATH=$PATH:~/.node/bin
Based on Vikas answer but with a slight modification: The Uri is received by parameter:
private void showPhoto(Uri photoUri){
Intent intent = new Intent();
intent.setAction(Intent.ACTION_VIEW);
intent.setDataAndType(photoUri, "image/*");
startActivity(intent);
}
Simply just use an ImageButton.
Elasticsearch supports this now out of the box:

Logger log = Logger.getLogger("myApp");
log.setLevel(Level.ALL);
log.info("initializing - trying to load configuration file ...");
//Properties preferences = new Properties();
try {
//FileInputStream configFile = new //FileInputStream("/path/to/app.properties");
//preferences.load(configFile);
InputStream configFile = myApp.class.getResourceAsStream("app.properties");
LogManager.getLogManager().readConfiguration(configFile);
} catch (IOException ex)
{
System.out.println("WARNING: Could not open configuration file");
System.out.println("WARNING: Logging not configured (console output only)");
}
log.info("starting myApp");
this is working..:) you have to pass InputStream in readConfiguration().
for testing purposes only you could Go to your facebook developer dashboard. create your app then in the top left corner open the apps dropdown menu and click create test app take the app ID and use instead.

I had a similar problem using Flask, but I did not have to resort to JSON. I just passed a list letters = ['a','b','c']
with render_template('show_entries.html', letters=letters)
, and set
var letters = {{ letters|safe }}
in my javascript code. Jinja2 replaced {{ letters }}
with ['a','b','c']
, which javascript interpreted as an array of strings.
The easiest solution I found is to just rename the php folder version as such:
That way only two of them will be read by MAMP. Done!
$("html, body").scrollTop($(element).offset().top); // <-- Also integer can be used
A bit too late, but this solution is nice and neat
const arr = [[1,2,3],[4,5,6],[7,8,9,10]]
for (let i of arr) {
for (let j of i) {
console.log(j) //Should log numbers from 1 to 10
}
}
Or in your case:
const arr = [[1,2,3],[4,5,6],[7,8,9]]
for (let [d1, d2, d3] of arr) {
console.log(`${d1}, ${d2}, ${d3}`) //Should return numbers from 1 to 9
}
Note: for ... of
loop is standardised in ES6, so only use this if you have an ES5 Javascript Complier (such as Babel)
Another note: There are alternatives, but they have some subtle differences and behaviours, such as forEach()
, for...in
, for...of
and traditional for()
. It depends on your case to decide which one to use. (ES6 also has .map()
, .filter()
, .find()
, .reduce()
)
The other solutions will work fine on initial page load, but calling $timeout from the controller is the only way to ensure that your function is called when the model changes. Here is a working fiddle that uses $timeout. For your example it would be:
.controller('myC', function ($scope, $timeout) {
$scope.$watch("ta", function (newValue, oldValue) {
$timeout(function () {
test();
});
});
ngRepeat will only evaluate a directive when the row content is new, so if you remove items from your list, onFinishRender will not fire. For example, try entering filter values in these fiddles emit.
A great real-world example of where lazy loading comes in handy is with ORM's (Object Relation Mappers) such as Entity Framework and NHibernate.
Say you have an entity Customer which has properties for Name, PhoneNumber, and Orders. Name and PhoneNumber are regular strings but Orders is a navigation property that returns a list of every order the customer ever made.
You often might want to go through all your customer's and get their name and phone number to call them. This is a very quick and simple task, but imagine if each time you created a customer it automatically went and did a complex join to return thousands of orders. The worst part is that you aren't even going to use the orders so it is a complete waste of resources!
This is the perfect place for lazy loading because if the Order property is lazy it will not go fetch all the customer's order unless you actually need them. You can enumerate the Customer objects getting only their Name and Phone Number while the Order property is patiently sleeping, ready for when you need it.
Expanding upon Gustavo Lima's answer. The same thing can be done without creating an entirely new list. The values in the list can be replaced with the differentials as the FOR
loop progresses.
def f_ClosestVal(v_List, v_Number):
"""Takes an unsorted LIST of INTs and RETURNS INDEX of value closest to an INT"""
for _index, i in enumerate(v_List):
v_List[_index] = abs(v_Number - i)
return v_List.index(min(v_List))
myList = [1, 88, 44, 4, 4, -2, 3]
v_Num = 5
print(f_ClosestVal(myList, v_Num)) ## Gives "3," the index of the first "4" in the list.
Add this to your external style sheet (preferred):
a {text-decoration:none;}
Or add this to the <head>
of your HTML document:
<style type="text/css">
a {text-decoration:none;}
</style>
Or add it to the a
element itself (not recommended):
<!-- Add [ style="text-decoration:none;"] -->
<a href="http://example.com" style="text-decoration:none;">Text</a>
//Element[@attribute1="abc" and @attribute2="xyz" and .="Data"]
The reason why I add this answer is that I want to explain the relationship of .
and text()
.
The first thing is when using []
, there are only two types of data:
[number]
to select a node from node-set[bool]
to filter a node-set from node-setIn this case, the value is evaluated to boolean by function boolean()
, and there is a rule:
Filters are always evaluated with respect to a context.
When you need to compare text()
or .
with a string "Data"
, it first uses string()
function to transform those to string type, than gets a boolean result.
There are two important rule about string()
:
The string()
function converts a node-set to a string by returning the string value of the first node in the node-set, which in some instances may yield unexpected results.
text()
is relative path that return a node-set contains all the text node of current node(context node), like ["Data"]
.
When it is evaluated by string(["Data"])
, it will return the first node of node-set, so you get "Data" only when there is only one text node in the node-set.
If you want the string()
function to concatenate all child text, you must then pass a single node instead of a node-set.
For example, we get a node-set ['a', 'b']
, you can pass there parent node to string(parent)
, this will return 'ab'
, and of cause string(.)
in you case will return an concatenated string "Data"
.
Both way will get same result only when there is a text node.
When you first read the body, you have to store it so once you're done with it, you can set a new io.ReadCloser
as the request body constructed from the original data. So when you advance in the chain, the next handler can read the same body.
One option is to read the whole body using ioutil.ReadAll()
, which gives you the body as a byte slice.
You may use bytes.NewBuffer()
to obtain an io.Reader
from a byte slice.
The last missing piece is to make the io.Reader
an io.ReadCloser
, because bytes.Buffer
does not have a Close()
method. For this you may use ioutil.NopCloser()
which wraps an io.Reader
, and returns an io.ReadCloser
, whose added Close()
method will be a no-op (does nothing).
Note that you may even modify the contents of the byte slice you use to create the "new" body. You have full control over it.
Care must be taken though, as there might be other HTTP fields like content-length and checksums which may become invalid if you modify only the data. If subsequent handlers check those, you would also need to modify those too!
If you also want to read the response body, then you have to wrap the http.ResponseWriter
you get, and pass the wrapper on the chain. This wrapper may cache the data sent out, which you can inspect either after, on on-the-fly (as the subsequent handlers write to it).
Here's a simple ResponseWriter
wrapper, which just caches the data, so it'll be available after the subsequent handler returns:
type MyResponseWriter struct {
http.ResponseWriter
buf *bytes.Buffer
}
func (mrw *MyResponseWriter) Write(p []byte) (int, error) {
return mrw.buf.Write(p)
}
Note that MyResponseWriter.Write()
just writes the data to a buffer. You may also choose to inspect it on-the-fly (in the Write()
method) and write the data immediately to the wrapped / embedded ResponseWriter
. You may even modify the data. You have full control.
Care must be taken again though, as the subsequent handlers may also send HTTP response headers related to the response data –such as length or checksums– which may also become invalid if you alter the response data.
Putting the pieces together, here's a full working example:
func loginmw(handler http.Handler) http.Handler {
return http.HandlerFunc(func(w http.ResponseWriter, r *http.Request) {
body, err := ioutil.ReadAll(r.Body)
if err != nil {
log.Printf("Error reading body: %v", err)
http.Error(w, "can't read body", http.StatusBadRequest)
return
}
// Work / inspect body. You may even modify it!
// And now set a new body, which will simulate the same data we read:
r.Body = ioutil.NopCloser(bytes.NewBuffer(body))
// Create a response wrapper:
mrw := &MyResponseWriter{
ResponseWriter: w,
buf: &bytes.Buffer{},
}
// Call next handler, passing the response wrapper:
handler.ServeHTTP(mrw, r)
// Now inspect response, and finally send it out:
// (You can also modify it before sending it out!)
if _, err := io.Copy(w, mrw.buf); err != nil {
log.Printf("Failed to send out response: %v", err)
}
})
}
This font is not standard on all devices. It is installed by default on some Macs, but rarely on PCs and mobile devices.
To use this font on all devices, use a @font-face declaration in your CSS to link to it on your domain if you wish to use it.
@font-face { font-family: Delicious; src: url('Delicious-Roman.otf'); }
@font-face { font-family: Delicious; font-weight: bold; src: url('Delicious-Bold.otf'); }
Taken from css3.info
I'll try and break it down (example from documention)
/*
* The cellForRowAtIndexPath takes for argument the tableView (so if the same object
* is delegate for several tableViews it can identify which one is asking for a cell),
* and an indexPath which determines which row and section the cell is returned for.
*/
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
/*
* This is an important bit, it asks the table view if it has any available cells
* already created which it is not using (if they are offScreen), so that it can
* reuse them (saving the time of alloc/init/load from xib a new cell ).
* The identifier is there to differentiate between different types of cells
* (you can display different types of cells in the same table view)
*/
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:@"MyIdentifier"];
/*
* If the cell is nil it means no cell was available for reuse and that we should
* create a new one.
*/
if (cell == nil) {
/*
* Actually create a new cell (with an identifier so that it can be dequeued).
*/
cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:@"MyIdentifier"] autorelease];
cell.selectionStyle = UITableViewCellSelectionStyleNone;
}
/*
* Now that we have a cell we can configure it to display the data corresponding to
* this row/section
*/
NSDictionary *item = (NSDictionary *)[self.content objectAtIndex:indexPath.row];
cell.textLabel.text = [item objectForKey:@"mainTitleKey"];
cell.detailTextLabel.text = [item objectForKey:@"secondaryTitleKey"];
NSString *path = [[NSBundle mainBundle] pathForResource:[item objectForKey:@"imageKey"] ofType:@"png"];
UIImage *theImage = [UIImage imageWithContentsOfFile:path];
cell.imageView.image = theImage;
/* Now that the cell is configured we return it to the table view so that it can display it */
return cell;
}
This is a DataSource
method so it will be called on whichever object has declared itself as the DataSource
of the UITableView
. It is called when the table view actually needs to display the cell onscreen, based on the number of rows and sections (which you specify in other DataSource methods).
I think the easiest way is to write a function to update your chart including the chart.update()
method. Check out this simple example I wrote in jsfiddle for a Bar Chart.

Hope this helps.
This is the initial database of the data source when you connect.
Edited for clarity:
If you have multiple databases in your SQL Server instance and you don't want to use the default database, you need some way to specify which one you are going to use.
Last column in your input file must have some data in it (be it space or char, but not null). I guess, 1st record contains null after last ',' which sqlldr won't recognize unless specifically asked to recognize nulls using TRAILING NULLCOLS option. Alternatively, if you don't want to use TRAILING NULLCOLS, you will have to take care of those NULLs before you pass the file to sqlldr. Hope this helps
Web Development Helper is very good.
The IE Dev Toolbar is often helpful, but unfortunately doesn't do script debugging
The following code does what is required
function doTest() {
SpreadsheetApp.getActiveSheet().getRange('F2').setValue('Hello');
}
I forgot to select Microsoft Office Developer Tools for installation initially. In my case Visual Studio Professional 2013 and also 2015.
string[] result = new string[table.Columns.Count];
DataRow dr = table.Rows[0];
for (int i = 0; i < dr.ItemArray.Length; i++)
{
result[i] = dr[i].ToString();
}
foreach (string str in result)
Console.WriteLine(str);
In awk, FNR
refers to the record number (typically the line number) in the current file and NR
refers to the total record number. The operator ==
is a comparison operator, which returns true when the two surrounding operands are equal.
This means that the condition NR==FNR
is only true for the first file, as FNR
resets back to 1 for the first line of each file but NR
keeps on increasing.
This pattern is typically used to perform actions on only the first file. The next
inside the block means any further commands are skipped, so they are only run on files other than the first.
The condition FNR==NR
compares the same two operands as NR==FNR
, so it behaves in the same way.
If your variable data1$c

Finding duplicate addresses is much more complex than it seems, especially if you require accuracy. A MySQL query is not enough in this case...
I work at SmartyStreets, where we do address validation and de-duplication and other stuff, and I've seen a lot of diverse challenges with similar problems.
There are several third-party services which will flag duplicates in a list for you. Doing this solely with a MySQL subquery will not account for differences in address formats and standards. The USPS (for US address) has certain guidelines to make these standard, but only a handful of vendors are certified to perform such operations.
So, I would recommend the best answer for you is to export the table into a CSV file, for instance, and submit it to a capable list processor. One such is LiveAddress which will have it done for you in a few seconds to a few minutes automatically. It will flag duplicate rows with a new field called "Duplicate" and a value of Y
in it.
After doing it both ways for a few projects my stance is that composer.lock
should not be committed as part of the project.
composer.lock
is build metadata which is not part of the project. The state of dependencies should be controlled through how you're versioning them (either manually or as part of your automated build process) and not arbitrarily by the last developer to update them and commit the lock file.
If you are concerned about your dependencies changing between composer updates then you have a lack of confidence in your versioning scheme. Versions (1.0, 1.1, 1.2, etc) should be immutable and you should avoid "dev-" and "X.*" wildcards outside of initial feature development.
Committing the lock file is a regression for your dependency management system as the dependency version has now gone back to being implicitly defined.
Also, your project should never have to be rebuilt or have its dependencies reacquired in each environment, especially prod. Your deliverable (tar, zip, phar, a directory, etc) should be immutable and promoted through environments without changing.
Tomcat is an application container that is also a web server. An application container can run web-applications (have "application" scope). It is not considered Some people do not consider it a full application server as it is lacking in some aspects such as user management and the like, but getting better all the time..
In your template, you have access to all the variables that are members of the current $scope
. So, tobedone
should be $scope.tobedone
, and then you can display it with {{tobedone}}
, or [[tobedone]]
in your case.
Another version of the function without error handling. This time it is not case sensitive and a little bit more efficient.

The rowSums function (as Greg mentions) will do what you want, but you are mixing subsetting techniques in your answer, do not use "$" when using "[]", your code should look something more like:
data$new <- rowSums( data[,43:167] )
If you want to use a function other than sum, then look at ?apply for applying general functions accross rows or columns.

move does not make sense for a hashmap since its a dictionary with a hashcode for bucketing based on key and then a linked list for colliding hashcodes resolved via equals. Use a TreeMap for sorted maps and then pass in a custom comparator.
Here's how I fixed it:
nltk.download()
.The download graphic window opened and all the packages got installed.I don't see any margin

margin-left: 0;

}
I always use the min and max macros for ints. I'm not sure why anyone would use fmin or fmax for integer values.
The big gotcha with min and max is that they're not functions, even if they look like them. If you do something like:
min (10, BigExpensiveFunctionCall())
That function call may get called twice depending on the implementation of the macro. As such, its best practice in my org to never call min or max with things that aren't a literal or variable.
The easiest and least confusing solution:
a = raw_input("Enter a: ")
b = raw_input("Enter b: ")
print "a + b as strings: %s" % a + b
a = int(a)
b = int(b)
c = a + b
print "a + b as integers: %d" % c

Use the Diff utility and extract only the lines starting with < in the output
You'll have more flexibility if you turn the values in your filter object into arrays:
var filter = {address: ['England'], name: ['Mark'] };
That way you can filter for things like "England" or "Scotland", meaning that results may include records for England, and for Scotland:
var filter = {address: ['England', 'Scotland'], name: ['Mark'] };
With that setup, your filtering function can be:
const applyFilter = (data, filter) => data.filter(obj =>
Object.entries(filter).every(([prop, find]) => find.includes(obj[prop]))
);
// demo
var users = [{name: 'John',email: '[email protected]',age: 25,address: 'USA'},{name: 'Tom',email: '[email protected]',age: 35,address: 'England'},{name: 'Mark',email: '[email protected]',age: 28,address: 'England'}];var filter = {address: ['England'], name: ['Mark'] };
var filter = {address: ['England'], name: ['Mark'] };
console.log(applyFilter(users, filter));

Suppose you have the following code:
import java.util.Map;
import java.util.concurrent.ConcurrentHashMap;
public class Test {
public static void main(String[] s) {
Map<String, Boolean> whoLetDogsOut = new ConcurrentHashMap<>();
whoLetDogsOut.computeIfAbsent("snoop", k -> f(k));
whoLetDogsOut.computeIfAbsent("snoop", k -> f(k));
}
static boolean f(String s) {
System.out.println("creating a value for \""+s+'"');
return s.isEmpty();
}
}
Then you will see the message creating a value for "snoop"
exactly once as on the second invocation of computeIfAbsent
there is already a value for that key. The k
in the lambda expression k -> f(k)
is just a placeolder (parameter) for the key which the map will pass to your lambda for computing the value. So in the example the key is passed to the function invocation.
Alternatively you could write: whoLetDogsOut.computeIfAbsent("snoop", k -> k.isEmpty());
to achieve the same result without a helper method (but you won’t see the debugging output then). And even simpler, as it is a simple delegation to an existing method you could write: whoLetDogsOut.computeIfAbsent("snoop", String::isEmpty);
This delegation does not need any parameters to be written.
To be closer to the example in your question, you could write it as whoLetDogsOut.computeIfAbsent("snoop", key -> tryToLetOut(key));
(it doesn’t matter whether you name the parameter k
or key
). Or write it as whoLetDogsOut.computeIfAbsent("snoop", MyClass::tryToLetOut);
if tryToLetOut
is static
or whoLetDogsOut.computeIfAbsent("snoop", this::tryToLetOut);
if tryToLetOut
is an instance method.
Here is the code
$str = substr($str, 1);

A useful extension is to collect the results in a Dictionary
for fast lookup (e.g. in a loop):
var resultDict = _dbContext.Projects

.Select(g => new { country = g.Key, count = g.Count() })
.ToDictionary(k => k.country, i => i.count);

x[~numpy.isnan(x)]
works. But it will throw an error if the numpy dtype is not a native data type, for example if it is object. In that case you can use pandas.
x[~pandas.isna(x)] or x[~pandas.isnull(x)]
I have found that using ._getexif
doesn't work in higher python versions, moreover, it is a protected class and one should avoid using it if possible.
After digging around the debugger this is what I found to be the best way to get the EXIF data for an image:
from PIL import Image
def get_exif(path):
return Image.open(path).info['parsed_exif']
This returns a dictionary of all the EXIF data of an image.
Note: For Python3.x use Pillow instead of PIL
Yes. I don't have any examples that I've done personally available right now. I'll post later when I find some. Basically you'll use reflection to load the assembly and then to pull whatever types you need for it.
In the meantime, this link should get you started:
Other than writings conditionals depending on what $SHELL/$TERM is set to, no. What's wrong with using Perl? It's pretty ubiquitous (I can't think of a single UNIX variant that doesn't have it), and it'll spare you the trouble.
Indeed. The thing is that the 2008 R2 version is very tricky. The JTDs driver seems to work on some cases. In a certain server, the jTDS worked fine for an 2008 R2 instance. In another server, though, I had to use Microsoft's JBDC driver sqljdbc4.jar. But then, it would only work after setting the JRE environment to 1.6(or higher).
I used 1.5 for the other server, so I waisted a lot of time on this.
Tricky issue.

In addition to the registers being used for mass operations, they are useful for their property of being preserved through a function call (call-preserved) in 32-bit calling convention. The ESI, EDI, EBX, EBP, ESP are call-preserved whereas EAX, ECX and EDX are not call-preserved. Call-preserved registers are respected by C library function and their values persist through the C library function calls.
Jeff Duntemann in his assembly language book has an example assembly code for printing the command line arguments. The code uses esi and edi to store counters as they will be unchanged by the C library function printf. For other registers like eax, ecx, edx, there is no guarantee of them not being used by the C library functions.
https://www.amazon.com/Assembly-Language-Step-Step-Programming/dp/0470497025
See section 12.8 How C sees Command-Line Arguments.
Note that 64-bit calling conventions are different from 32-bit calling conventions, and I am not sure if these registers are call-preserved or not.
I created my own functions which work really nicely:
def writeDict(dict, filename, sep):
with open(filename, "a") as f:
for i in dict.keys():
f.write(i + " " + sep.join([str(x) for x in dict[i]]) + "\n")
It will store the keyname first, followed by all values. Note that in this case my dict contains integers so that's why it converts to int
. This is most likely the part you need to change for your situation.
def readDict(filename, sep):
with open(filename, "r") as f:
dict = {}
for line in f:
values = line.split(sep)
dict[values[0]] = {int(x) for x in values[1:len(values)]}
return(dict)
Suppose df is a pandas DataFrame then to get number of non-null values and data types of all column at once use:
df.info()
You can use the extension method below:
public static string GetStringBetween(this string token, string first, string second)
{
if (!token.Contains(first)) return "";
var afterFirst = token.Split(new[] { first }, StringSplitOptions.None)[1];
if (!afterFirst.Contains(second)) return "";
var result = afterFirst.Split(new[] { second }, StringSplitOptions.None)[0];
return result;
}
Usage is:
var token = "super exemple of string key : text I want to keep - end of my string";
var keyValue = token.GetStringBetween("key : ", " - ");
The filter function wasn't working for me at all; maybe the more recent version of jquery doesn't perform as the version used in above code. Regardless; I used:
var black = $('.black');
var white = $('.white');
The selector will find every element classed under black or white. Button functions stay as stated above:
$('#showBlackButton').click(function() {
black.show();
white.hide();
});
$('#showWhiteButton').click(function() {
white.show();
black.hide();
});
To expand on the answer I came here to get a better understanding so I wrote this that can explain it and helped me too.
It has the setlocal DisableDelayedExpansion
in there so you can locally set this as you wish between the setlocal EnableDelayedExpansion
and it.
@echo off

for /f "tokens=*" %%A in ("Some Thing") do (
setlocal EnableDelayedExpansion
set z=%%A
echo !z! Echoing the assigned variable in setlocal scope.
echo %%A Echoing the variable in local scope.
setlocal DisableDelayedExpansion
echo !z! &rem !z! Neither of these now work, which makes sense.
echo %z% &rem ECHO is off. Neither of these now work, which makes sense.
echo %%A Echoing the variable in its local scope, will always work.

Regexes are fundamentally bad at parsing HTML (see Can you provide some examples of why it is hard to parse XML and HTML with a regex? for why). What you need is an HTML parser. See Can you provide an example of parsing HTML with your favorite parser? for examples using a variety of parsers.
In particular you will want to look at the Python answers: BeautifulSoup, HTMLParser, and lxml.
I had this need once and created a small library for, which maintains the CSS documents
https://github.com/terotests/css
With that you can state
css().bind("TD:hover", {
"background" : "00ff00"
});
It uses the techniques mentioned above and also tries to take care of the cross-browser issues. If there for some reason exists an old browser like IE9 it will limit the number of STYLE tags, because the older IE browser had this strange limit for number of STYLE tags available on the page.
Also, it limits the traffic to the tags by updating tags only periodically. There is also a limited support for creating animation classes.
This should work. You may save the following in a batch file:
TASKKILL /F /IM chrome.exe
start chrome.exe --args --disable-web-security
pause
String names[] = new String[]{"Avinash","Amol","John","Peter"};
java.util.List<String> namesList = Arrays.asList(names);
or
String names[] = new String[]{"Avinash","Amol","John","Peter"};
java.util.List<String> temp = Arrays.asList(names);
Above Statement adds the wrapper on the input array. So the methods like add & remove will not be applicable on list reference object 'namesList'.
If you try to add an element in the existing array/list then you will get "Exception in thread "main" java.lang.UnsupportedOperationException".
The above operation is readonly or viewonly.
We can not perform add or remove operation in list object.
But
String names[] = new String[]{"Avinash","Amol","John","Peter"};
java.util.ArrayList<String> list1 = new ArrayList<>(Arrays.asList(names));
or
String names[] = new String[]{"Avinash","Amol","John","Peter"};
java.util.List<String> listObject = Arrays.asList(names);
java.util.ArrayList<String> list1 = new ArrayList<>(listObject);
In above statement you have created a concrete instance of an ArrayList class and passed a list as a parameter.
In this case method add & remove will work properly as both methods are from ArrayList class so here we won't get any UnSupportedOperationException.
Changes made in Arraylist object (method add or remove an element in/from an arraylist) will get not reflect in to original java.util.List object.
String names[] = new String[] {
"Avinash",
"Amol",
"John",
"Peter"
};
java.util.List < String > listObject = Arrays.asList(names);
java.util.ArrayList < String > list1 = new ArrayList < > (listObject);
for (String string: list1) {
System.out.print(" " + string);
}
list1.add("Alex"); //Added without any exception
list1.remove("Avinash"); //Added without any exception will not make any changes in original list in this case temp object.
for (String string: list1) {
System.out.print(" " + string);
}
String existingNames[] = new String[] {
"Avinash",
"Amol",
"John",
"Peter"
};
java.util.List < String > namesList = Arrays.asList(names);
namesList.add("Bob"); // UnsupportedOperationException occur
namesList.remove("Avinash"); //UnsupportedOperationException

Error Code: 1005 -- there is a wrong primary key reference in your code
Usually it's due to a referenced foreign key field that does not exist. It might be you have a typo mistake, or check case it should be same, or there's a field-type mismatch. Foreign key-linked fields must match definitions exactly.
Some known causes may be:
INT(10)
the key field needs to be INT(10)

The postition:absolute;
tag positions the element relative to it's immediate parent.
I noticed that even in the examples, there isn't room for scrolling, and when i tried it out, it didn't work.
Therefore, to pull off the facebook floating menu, the position:fixed;
tag should be used instead. It displaces/keeps the element at the given/specified location, and the rest of the page can scroll smoothly - even with the responsive ones.
Please see CSS postion attribute documentation when you can :)
That is taking the parameter by reference. So in the first case you are taking a pointer parameter by reference so whatever modification you do to the value of the pointer is reflected outside the function. Second is the simlilar to first one with the only difference being that it is a double pointer. See this example:
void pass_by_value(int* p)
{
//Allocate memory for int and store the address in p
p = new int;
}
void pass_by_reference(int*& p)
{
p = new int;
}
int main()
{
int* p1 = NULL;
int* p2 = NULL;
pass_by_value(p1); //p1 will still be NULL after this call
pass_by_reference(p2); //p2 's value is changed to point to the newly allocate memory
return 0;
}

The approved solution doesn't work in my case, so my solution is the following one:
''' The column name in the example case is "Unnamed: 7"
but it works with any other name ("Unnamed: 0" for example). '''
df.rename({"Unnamed: 7":"a"}, axis="columns", inplace=True)
# Then, drop the column as usual.
df.drop(["a"], axis=1, inplace=True)

The accented Latin range \u00C0-\u017F
was not quite enough for my database of names, so I extended the regex to
[a-zA-Z\u00C0-\u024F]
[a-zA-Z\u00C0-\u024F\u1E00-\u1EFF] // includes even more Latin chars
I added these code blocks (\u00C0-\u024F
includes three adjacent blocks at once):
\u00C0-\u00FF
Latin-1 Supplement\u0100-\u017F
Latin Extended-A\u0180-\u024F
Latin Extended-B\u1E00-\u1EFF
Latin Extended AdditionalNote that \u00C0-\u00FF
is actually only a part of Latin-1 Supplement. It skips unprintable control signals and all symbols except for the awkwardly-placed multiply × \u00D7
and divide ÷ \u00F7
.
[a-zA-Z\u00C0-\u00D6\u00D8-\u00F6\u00F8-\u024F] // exclude ×÷
If you need more code points, you can find more ranges on Wikipedia's List of Unicode characters. For example, you could also add Latin Extended-C, D, and E, but I left them out because only historians seem interested in them now, and the D and E sets don't even render correctly in my browser.
The original regex stopping at \u017F
borked on the name "?enol". According to FontSpace's Unicode Analyzer, that first character is \u0218
, LATIN CAPITAL LETTER S WITH COMMA BELOW. (Yeah, it's usually spelled with a cedilla-S \u015E
, "Senol." But I'm not flying to Turkey to go tell him, "You're spelling your name wrong!")

To add more examples to Chuck's answer:
With parameter:
case a
when 1
puts "Single value"
when 2, 3
puts "One of comma-separated values"
when 4..6
puts "One of 4, 5, 6"
when 7...9
puts "One of 7, 8, but not 9"
else
puts "Any other thing"
end
Without parameter:
case
when b < 3
puts "Little than 3"
when b == 3
puts "Equal to 3"
when (1..10) === b
puts "Something in closed range of [1..10]"
end
Please, be aware of "How to write a switch statement in Ruby" that kikito warns about.
You can additionally implement IDataErrorInfo
as follows in the view model. If you implement IDataErrorInfo
, you can do the validation in that instead of the setter of a particular property, then whenever there is a error, return an error message so that the text box which has the error gets a red box around it, indicating an error.
class ViewModel : INotifyPropertyChanged, IDataErrorInfo
{
private string m_Name = "Type Here";
public ViewModel()
{
}
public string Name
{
get
{
return m_Name;
}
set
{
if (m_Name != value)
{
m_Name = value;
OnPropertyChanged("Name");
}
}
}
public event PropertyChangedEventHandler PropertyChanged;
protected void OnPropertyChanged(string propertyName)
{
if (PropertyChanged != null)
{
PropertyChanged(this, new PropertyChangedEventArgs(propertyName));
}
}
public string Error
{
get { return "...."; }
}
/// <summary>
/// Will be called for each and every property when ever its value is changed
/// </summary>
/// <param name="columnName">Name of the property whose value is changed</param>
/// <returns></returns>
public string this[string columnName]
{
get
{
return Validate(columnName);
}
}
private string Validate(string propertyName)
{
// Return error message if there is error on else return empty or null string
string validationMessage = string.Empty;
switch (propertyName)
{
case "Name": // property name
// TODO: Check validiation condition
validationMessage = "Error";
break;
}
return validationMessage;
}
}
And you have to set ValidatesOnDataErrors=True
in the XAML in order to invoke the methods of IDataErrorInfo
as follows:
<TextBox Text="{Binding Name, UpdateSourceTrigger=PropertyChanged, ValidatesOnDataErrors=True}" />
I have had the same error recently. I have checked the folder Log of my Server instance.
x:\Program Files\Microsoft SQL Server\MSSQL11.MSSQLSERVER\MSSQL\Log\
and I have found this errors in logs
Starting up database 'master'.
Error: 17204, Severity: 16, State: 1.
FCB::Open failed: Could not open file

SQL Server shutdown has been initiated
So for me it was an easy fix. I just added proper access rights to this files to the sql server service account. I hope it will help
Since you're transferring data in xml, you could also (un)marshal directly from/to pojos.
There's an example (and more info) in the jersey user guide, which I copy here:
POJO with JAXB annotations:
@XmlRootElement
public class Planet {
public int id;
public String name;
public double radius;
}
Resource:
@Path("planet")
public class Resource {
@GET
@Produces(MediaType.APPLICATION_XML)
public Planet getPlanet() {
Planet p = new Planet();
p.id = 1;
p.name = "Earth";
p.radius = 1.0;
return p;
}
@POST
@Consumes(MediaType.APPLICATION_XML)
public void setPlanet(Planet p) {
System.out.println("setPlanet " + p.name);
}
}
The xml that gets produced/consumed:
<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<planet>
<id>1</id>
<name>Earth</name>
<radius>1.0</radius>
</planet>
Something like this should work
var text = $('#toptitle').text();
if (text == 'Profil'){
$('#toptitle').text('New Word');
}
sDom: "Tfrtip" or via a callback:
"fnHeaderCallback": function(){
$('#YOURTABLENAME-table_length').hide();
}
You can implement your OTF
font using @font-face like:
@font-face {
font-family: GraublauWeb;
src: url("path/GraublauWeb.otf") format("opentype");
}
@font-face {
font-family: GraublauWeb;
font-weight: bold;
src: url("path/GraublauWebBold.otf") format("opentype");
}
// Edit: OTF now works in most browsers, see comments
However if you want to support a wide variety of browsers i would recommend you to switch to WOFF
and TTF
font types. WOFF
type is implemented by every major desktop browser, while the TTF
type is a fallback for older Safari, Android and iOS browsers. If your font is a free font, you could convert your font using for example a transfonter.
@font-face {
font-family: GraublauWeb;
src: url("path/GraublauWebBold.woff") format("woff"), url("path/GraublauWebBold.ttf") format("truetype");
}
If you want to support nearly every browser that is still out there (not necessary anymore IMHO), you should add some more font-types like:
@font-face {
font-family: GraublauWeb;
src: url("webfont.eot"); /* IE9 Compat Modes */
src: url("webfont.eot?#iefix") format("embedded-opentype"), /* IE6-IE8 */
url("webfont.woff") format("woff"), /* Modern Browsers */
url("webfont.ttf") format("truetype"), /* Safari, Android, iOS */
url("webfont.svg#svgFontName") format("svg"); /* Legacy iOS */
}
You can read more about why all these types are implemented and their hacks here. To get a detailed view of which file-types are supported by which browsers, see:
hope this helps
You can also use defaultdict to address this situation. It goes something like this:
from collections import defaultdict
#initialises the dictionary with values as list
aTargetDictionary = defaultdict(list)
for aKey in aSourceDictionary:
aTargetDictionary[aKey].append(aSourceDictionary[aKey])
dir()
is the simple way. See here:
DataTable
's Select
method only supports simple filtering expressions like {field} = {value}
. It does not support complex expressions, let alone SQL/Linq statements.
You can, however, use Linq extension methods to extract a collection of DataRow
s then create a new DataTable
.
dt = dt.AsEnumerable()
.GroupBy(r => new {Col1 = r["Col1"], Col2 = r["Col2"]})
.Select(g => g.OrderBy(r => r["PK"]).First())
.CopyToDataTable();
This is quite late but might help some others. I do what you want to do by adding two git hooks to my repository.
.git/hooks/pre-commit:
#!/bin/bash
#
# A hook script called by "git commit" with no arguments. The hook should
# exit with non-zero status after issuing an appropriate message if it wants
# to stop the commit.
SELF_DIR=`git rev-parse --show-toplevel`
DATABASE=$SELF_DIR/.permissions
# Clear the permissions database file
> $DATABASE
echo -n "Backing-up permissions..."
IFS_OLD=$IFS; IFS=$'\n'
for FILE in `git ls-files --full-name`
do
# Save the permissions of all the files in the index
echo $FILE";"`stat -c "%a;%U;%G" $FILE` >> $DATABASE
done
for DIRECTORY in `git ls-files --full-name | xargs -n 1 dirname | uniq`
do
# Save the permissions of all the directories in the index
echo $DIRECTORY";"`stat -c "%a;%U;%G" $DIRECTORY` >> $DATABASE
done
IFS=$IFS_OLD
# Add the permissions database file to the index
git add $DATABASE -f
echo "OK"
.git/hooks/post-checkout:
#!/bin/bash
SELF_DIR=`git rev-parse --show-toplevel`
DATABASE=$SELF_DIR/.permissions
echo -n "Restoring permissions..."
IFS_OLD=$IFS; IFS=$'\n'
while read -r LINE || [[ -n "$LINE" ]];
do
ITEM=`echo $LINE | cut -d ";" -f 1`
PERMISSIONS=`echo $LINE | cut -d ";" -f 2`
USER=`echo $LINE | cut -d ";" -f 3`
GROUP=`echo $LINE | cut -d ";" -f 4`
# Set the file/directory permissions
chmod $PERMISSIONS $ITEM
# Set the file/directory owner and groups
chown $USER:$GROUP $ITEM
done < $DATABASE
IFS=$IFS_OLD
echo "OK"
exit 0
The first hook is called when you "commit" and will read the ownership and permissions for all the files in the repository and store them in a file in the root of the repository called .permissions and then add the .permissions file to the commit.
The second hook is called when you "checkout" and will go through the list of files in the .permissions file and restore the ownership and permissions of those files.
I found solution. The call:
-(void) someMethod{
UIButton * but;
but.tag = 1;//some id button that you choice
[but addTarget:self action:@selector(buttonPressed:) forControlEvents:UIControlEventTouchUpInside];
}
And here the method called:
-(void) buttonPressed : (id) sender{
UIButton *clicked = (UIButton *) sender;
NSLog(@"%d",clicked.tag);//Here you know which button has pressed
}
