I'm not sure I understand the question correctly, but if you want to prevent people from writing in the input field you can use the disabled
attribute.
<input disabled="disabled" id="price_from" value="price from ">
In my case, I am using a tiny .exe that reloads the referenced DLLs via Reflection. So I just do these steps which saves my day:
From project properties on solution explorer, at build tab, I choose target platfrom x86
str = "aaaaabbbb"
newstr = str[-4:]
This can be achieved using dplyr package, which is available in CRAN. The simple way to achieve this:
dplyr
package. library(dplyr)
df<- select(filter(dat,name=='tom'| name=='Lynn'), c('days','name))
Explanation:
So, once we’ve downloaded dplyr, we create a new data frame by using two different functions from this package:
filter: the first argument is the data frame; the second argument is the condition by which we want it subsetted. The result is the entire data frame with only the rows we wanted. select: the first argument is the data frame; the second argument is the names of the columns we want selected from it. We don’t have to use the names() function, and we don’t even have to use quotation marks. We simply list the column names as objects.
I just wanted to add this version because this is such a useful thread and I think this is a very simple implementation. I have used this multiple times in various types if multithreaded application:
Task.Factory.StartNew(() =>
{
DoLongRunningWork();
Application.Current.Dispatcher.BeginInvoke(DispatcherPriority.Normal, new Action(() =>
{ txt.Text = "Complete"; }));
});
And if you want to avoid the restart of the application, you can move out the appSettings
section:
<appSettings configSource="Config\appSettings.config"/>
to a separate file. And in combination with ConfigurationSaveMode.Minimal
var config = System.Web.Configuration.WebConfigurationManager.OpenWebConfiguration("~");
config.Save(ConfigurationSaveMode.Minimal);
you can continue to use the appSettings
section as the store for various settings without causing application restarts and without the need to use a file with a different format than the normal appSettings section.
Try this and it will work like a charm. I was having the same error but this approach did the trick for me:
ssh USER@REMOTE "cat file"|xclip -i
I followed Alohci's recommendation of looping in reverse because it's a live nodeList
. Here's what I did for those who are curious...
var activeObjects = documents.getElementsByClassName('active'); // a live nodeList
//Use a reverse-loop because the array is an active NodeList
while(activeObjects.length > 0) {
var lastElem = activePaths[activePaths.length-1]; //select the last element
//Remove the 'active' class from the element.
//This will automatically update the nodeList's length too.
var className = lastElem.getAttribute('class').replace('active','');
lastElem.setAttribute('class', className);
}
Here is an example of SIGSEGV.
root@pierr-desktop:/opt/playGround# cat test.c
int main()
{
int * p ;
* p = 0x1234;
return 0 ;
}
root@pierr-desktop:/opt/playGround# g++ -o test test.c
root@pierr-desktop:/opt/playGround# ./test
Segmentation fault
And here is the detail.
How to handle it?
Avoid it as much as possible in the first place.
Program defensively: use assert(), check for NULL pointer , check for buffer overflow.
Use static analysis tools to examine your code.
compile your code with -Werror -Wall.
Has somebody review your code.
When that actually happened.
Examine you code carefully.
Check what you have changed since the last time you code run successfully without crash.
Hopefully, gdb will give you a call stack so that you know where the crash happened.
EDIT : sorry for a rush. It should be *p = 0x1234;
instead of p = 0x1234

If you have several figures or subplots that you want to modify, it can be helpful to use the matplotlib context manager to change the color, instead of changing each one individually. The context manager allows you to temporarily change the rc parameters only for the immediately following indented code, but does not affect the global rc parameters.
This snippet yields two figures, the first one with modified colors for the axis, ticks and ticklabels, and the second one with the default rc parameters.
import matplotlib.pyplot as plt
with plt.rc_context({'axes.edgecolor':'orange', 'xtick.color':'red', 'ytick.color':'green', 'figure.facecolor':'white'}):
# Temporary rc parameters in effect
fig, (ax1, ax2) = plt.subplots(1,2)
ax1.plot(range(10))
ax2.plot(range(10))
# Back to default rc parameters
fig, ax = plt.subplots()
ax.plot(range(10))
You can type plt.rcParams
to view all available rc parameters, and use list comprehension to search for keywords:
# Search for all parameters containing the word 'color'
[(param, value) for param, value in plt.rcParams.items() if 'color' in param]
here is a good solution to use CDN and offline scripts
I use this code in every application I build, so you can use this in any app.
Included Scripts:
STEP1:
put this code in config/main.php
'params'=>array(
'cdn'=>true, // or false
...
STEP2:
create resoreses folder in root app folder and put your script there
res/
--js
--css
--img
--lib
--style
..
STEP3:
put this code in components/controller.php
public function registerDefaults()
{
$cs = Yii::app()->clientScript;

}
STEP4:
call the functions like this in //layouts/main.php
Yii::app()->getController()->registerDefaults();
Yii::app()->getController()->registerFontAwesome();
Yii::app()->getController()->registerGoogleAnalytics();
I agree with szajmon. The only problem with his and Quentin's answers is cross-browser compatibility.
HTML:
<div class="g">
<div>bla</div>
</div>
CSS:
.g {
background-image: -webkit-linear-gradient(300deg, white, black, white); /* webkit browsers (Chrome & Safari) */
background-image: -moz-linear-gradient(300deg, white, black, white); /* Mozilla browsers (Firefox) */
filter: progid:DXImageTransform.Microsoft.gradient(startColorstr='#ffffff', endColorstr='#000000', gradientType='1'); /* Internet Explorer */
background-image: -o-linear-gradient(300deg,rgb(255,255,255),rgb(0,0,0) 50%,rgb(255,255,255) 100%); /* Opera */
}
.g > div { background: #fff; }
\b in regular expressions match word boundaries (i.e. the location between the first word character and non-word character):
$ echo "bar embarassment" | sed "s/\bbar\b/no bar/g"
no bar embarassment
I have had major issues with ajax + jQuery v3 getting both the response status code and data from JSON APIs. jQuery.ajax only decodes JSON data if the status is a successful one, and it also swaps around the ordering of the callback parameters depending on the status code. Ugghhh.
The best way to combat this is to call the .always
chain method and do a bit of cleaning up. Here is my code.
$.ajax({
...
}).always(function(data, textStatus, xhr) {
var responseCode = null;
if (textStatus === "error") {
// data variable is actually xhr
responseCode = data.status;
if (data.responseText) {
try {
data = JSON.parse(data.responseText);
} catch (e) {
// Ignore
}
}
} else {
responseCode = xhr.status;
}
console.log("Response code", responseCode);
console.log("JSON Data", data);
});
Just a basic example:
RelativeLayout.LayoutParams params = new RelativeLayout.LayoutParams(RelativeLayout.LayoutParams.WRAP_CONTENT, RelativeLayout.LayoutParams.WRAP_CONTENT);
params.addRule(RelativeLayout.ALIGN_PARENT_LEFT, RelativeLayout.TRUE);
Button button1;
button1.setLayoutParams(params);
params = new RelativeLayout.LayoutParams(RelativeLayout.LayoutParams.WRAP_CONTENT, RelativeLayout.LayoutParams.WRAP_CONTENT);
params.addRule(RelativeLayout.RIGHT_OF, button1.getId());
Button button2;
button2.setLayoutParams(params);
As you can see, this is what you have to do:
RelativeLayout.LayoutParams
object.addRule(int)
or addRule(int, int)
to set the rules. The first method is used to add rules that don't require values.This is my personal solution, based on the information here (this thread):
var Divs = new Array();
var Elemns = document.getElementsByClassName("divisao");
try {
Divs = Elemns.prototype.slice.call(Elemns);
} catch(e) {
Divs = $A(Elemns);
}
Where $A was described by Gareth Davis in his post:
function $A(iterable) {
if (!iterable) return [];
if ('toArray' in Object(iterable)) return iterable.toArray();
var length = iterable.length || 0, results = new Array(length);
while (length--) results[length] = iterable[length];
return results;
}
If browser supports the best way, ok, otherwise will use the cross browser.
Or by direct string access:
$string[strlen($string)-1];
Note that this doesn't work for multibyte strings. If you need to work with multibyte string, consider using the mb_*
string family of functions.
As of PHP 7.1.0 negative numeric indices are also supported, e.g just $string[-1];
what about changing the position: relative on your #content #text div to position: absolute
#content #text {
position:absolute;
width:950px;
height:215px;
color:red;
}
then you can use the css properties left and top to position within the #content div
"
git fetch
" (hence "git pull
" as well) learned to check "fetch.prune
" and "remote.*.prune
" configuration variables and to behave as if the "--prune
" command line option was given.
That means that, if you set remote.origin.prune to true:
git config remote.origin.prune true
Any git fetch
or git pull
will automatically prune.
Note: Git 2.12 (Q1 2017) will fix a bug related to this configuration, which would make git remote rename
misbehave.
See "How do I rename a git remote?".
See more at commit 737c5a9:
Without "
git fetch --prune
", remote-tracking branches for a branch the other side already has removed will stay forever.
Some people want to always run "git fetch --prune
".To accommodate users who want to either prune always or when fetching from a particular remote, add two new configuration variables "
fetch.prune
" and "remote.<name>.prune
":
- "
fetch.prune
" allows to enable prune for all fetch operations.- "
remote.<name>.prune
" allows to change the behaviour per remote.The latter will naturally override the former, and the
--[no-]prune
option from the command line will override the configured default.Since
--prune
is a potentially destructive operation (Git doesn't keep reflogs for deleted references yet), we don't want to prune without users consent, so this configuration will not be on by default.
in C++ expression a % b
returns remainder of division of a by b (if they are positive. For negative numbers sign of result is implementation defined). For example:
5 % 2 = 1
13 % 5 = 3
With this knowledge we can try to understand your code. Condition count % 6 == 5
means that newline will be written when remainder of division count by 6 is five. How often does that happen? Exactly 6 lines apart (excercise : write numbers 1..30 and underline the ones that satisfy this condition), starting at 6-th line (count = 5).
To get desired behaviour from your code, you should change condition to count % 5 == 4
, what will give you newline every 5 lines, starting at 5-th line (count = 4).
You are checking Parent
properties for null in your delegate. The same should work with lambda expressions too.
List<AnalysisObject> analysisObjects = analysisObjectRepository
.FindAll()
.Where(x =>
(x.ID == packageId) ||
(x.Parent != null &&
(x.Parent.ID == packageId ||
(x.Parent.Parent != null && x.Parent.Parent.ID == packageId)))
.ToList();
Use git clone
with the --depth
option set to 1
to create a shallow clone with a history truncated to the latest commit.
For example:
git clone --depth 1 https://github.com/user/repo.git
To also initialize and update any nested submodules, also pass --recurse-submodules
and to clone them shallowly, also pass --shallow-submodules
.
For example:
git clone --depth 1 --recurse-submodules --shallow-submodules https://github.com/user/repo.git
When I pass a little complex DOM query to $._data like this: $._data($('#outerWrap .innerWrap ul li:last a'), 'events')
it throws undefined in the browser console.
So I had to use $._data on the parent div: $._data($('#outerWrap')[0], 'events')
to see the events for the a tags. Here is a JSFiddle for the same: http://jsfiddle.net/giri_jeedigunta/MLcpT/4/
It is simple. The first thing that you have to understand the design of the Python interpreter. It doesn't allocate memory for all the variables basically if any two or more variable has the same value it just map to that value.
let's go to the code example,
In [6]: a = 10
In [7]: id(a)
Out[7]: 10914656
In [8]: b = 10
In [9]: id(b)
Out[9]: 10914656
In [10]: c = 11
In [11]: id(c)
Out[11]: 10914688
In [12]: d = 21
In [13]: id(d)
Out[13]: 10915008
In [14]: e = 11
In [15]: id(e)
Out[15]: 10914688
In [16]: e = 21
In [17]: id(e)
Out[17]: 10915008
In [18]: e is d
Out[18]: True
In [19]: e = 30
In [20]: id(e)
Out[20]: 10915296
From the above output, variables a and b shares the same memory, c and d has different memory when I create a new variable e and store a value (11) which is already present in the variable c so it mapped to that memory location and doesn't create a new memory when I change the value present in the variable e to 21 which is already present in the variable d so now variables d and e share the same memory location. At last, I change the value in the variable e to 30 which is not stored in any other variable so it creates a new memory for e.
so any variable which is having same value shares the memory.
Not for list and dictionary objects
let's come to your question.
when multiple keys have same value then all shares same memory so the thing that you expect is already there in python.
you can simply use it like this
In [49]: dictionary = {
...: 'k1':1,
...: 'k2':1,
...: 'k3':2,
...: 'k4':2}
...:
...:
In [50]: id(dictionary['k1'])
Out[50]: 10914368
In [51]: id(dictionary['k2'])
Out[51]: 10914368
In [52]: id(dictionary['k3'])
Out[52]: 10914400
In [53]: id(dictionary['k4'])
Out[53]: 10914400
From the above output, the key k1 and k2 mapped to the same address which means value one stored only once in the memory which is multiple key single value dictionary this is the thing you want. :P
just use this attribute
[System.Web.Http.HttpGet]
not need this line of code:
[System.Web.Http.AcceptVerbs("GET", "POST")]
Don't post them to your site.
Otherwise it is not possible.
You can use either this in the onCreate() method of the activity
this.getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_STATE_ALWAYS_HIDDEN);
or paste this code in the Activity tags in AndroidManifest.xml
android:windowSoftInputMode="stateVisible"
Log.WriteLine("Value of CompanyName column:" + thisReader["CompanyName"]);

How do you run PowerShell built-in scripts inside of your scripts?
How do you use built-in scripts like
Get-Location
pwd
ls
dir
split-path
::etc...
Those are ran by your computer, automatically checking the path of the script.
Similarly, I can run my custom scripts by just putting the name of the script in the script-block
::sid.ps1 is a PS script I made to find the SID of any user
::it takes one argument, that argument would be the username
echo $(sid.ps1 jowers)
(returns something like)> S-X-X-XXXXXXXX-XXXXXXXXXX-XXX-XXXX
$(sid.ps1 jowers).Replace("S","X")
(returns same as above but with X instead of S)
Go on to the powershell command line and type
> $profile
This will return the path to a file that our PowerShell command line will execute every time you open the app.
It will look like this
C:\Users\jowers\OneDrive\Documents\WindowsPowerShell\Microsoft.PowerShellISE_profile.ps1
Go to Documents and see if you already have a WindowsPowerShell directory. I didn't, so
> cd \Users\jowers\Documents
> mkdir WindowsPowerShell
> cd WindowsPowerShell
> type file > Microsoft.PowerShellISE_profile.ps1
We've now created the script that will launch every time we open the PowerShell App.
The reason we did that was so that we could add our own folder that holds all of our custom scripts. Let's create that folder and I'll name it "Bin" after the directories that Mac/Linux hold its scripts in.
> mkdir \Users\jowers\Bin
Now we want that directory to be added to our $env:path
variable every time we open the app so go back to the WindowsPowerShell
Directory and
> start Microsoft.PowerShellISE_profile.ps1
Then add this
$env:path += ";\Users\jowers\Bin"
Now the shell will automatically find your commands, as long as you save your scripts in that "Bin" directory.
Relaunch the powershell and it should be one of the first scripts that execute.
Run this on the command line after reloading to see your new directory in your path variable:
> $env:Path
Now we can call our scripts from the command line or from within another script as simply as this:
$(customScript.ps1 arg1 arg2 ...)
As you see we must call them with the .ps1
extension until we make aliases for them. If we want to get fancy.
If double quotes does not work , try including the string within square brackets.
For eg:
SELECT "Business Name","Other Name" FROM your_Table
can be changed as
SELECT [Business Name],[Other Name] FROM your_Table
You can add it programmatically or in the markup, but if you add it programmatically, rather than Add
the item, you should Insert
it as position zero so that it is the first item:
ddlColor.DataSource = from p in db.ProductTypes
where p.ProductID == pID
orderby p.Color
select new { p.Color };
ddlColor.DataTextField = "Color";
ddlColor.DataBind();
ddlColor.Items.Insert(0, new ListItem("Select Color", "");
The default item is expected to be the first item in the list. If you just Add
it, it will be on the bottom and will not be selected by default.
You can use ClientScript.RegisterStartUpScript to inject javascript into the page on Page_Load.
Here's a link to MSDN reference: http://msdn.microsoft.com/en-us/library/asz8zsxy.aspx
Here's the code in Page_Load:
List<string> tempString = new List<string>();
tempString.Add("Hello");
tempString.Add("World");
StringBuilder sb = new StringBuilder();
sb.Append("<script>");
sb.Append("var testArray = new Array;");
foreach(string str in tempString)
{
sb.Append("testArray.push('" + str + "');");
}
sb.Append("</script>");
ClientScript.RegisterStartupScript(this.GetType(), "TestArrayScript", sb.ToString());
Notes: Use StringBuilder to build the script string as it will probably be long.
And here's the Javascript that checks for the injected array "testArray" before you can work with it:
if (testArray)
{
// do something with testArray
}
There's 2 problems here:
Some consider this intrusive for C# to inject Javascript
We'll have to declare the array at a global context
If you can't live with that, another way would be to have the C# code save the Array into View State, then have the JavaScript use PageMethods (or web services) to call back to the server to get that View State object as an array. But I think that may be overkill for something like this.
I can answer this question only for Ubuntu users:
The root directory of docker can be found when you run the command docker info
Docker directory will be given in this line: "Docker Root Dir: /var/lib/docker
"
About the docker images, they are stored inside the docker directory:
/var/lib/docker/aufs/diff/
Remember these things are not same in all version of docker. Currently, I am using 1.12.3.
I know I am quite late to answer this but I have come up with a different answer:
val rdd = sc.textFile("/home/training/mydata/file.txt")
val text = rdd.map(lines=lines.split(",")).map(arrays=>(ararys(0),arrays(1))).toDF("id","name").show
I use this solution:
It's a bit more concise since I use: ng-repeat="obj in objects | filter : paginate"
to filter the rows. Also made it working with $resource:
SELECT SUBSTR(thatColumn, 1, 1) As NewColumn from student

I'm not sure if I understand your question, but I'll take a stab at it:
td {
border: 1px solid #000;
}
tr td:last-child {

white-space: nowrap;
}
_x000D_
<table style="width: 100%;">

<td class="block">this should stretch</td>
<td class="block">this should be the content width</td>

For Windows Forms you can control cursor position (and selection) with txtbox.SelectionStart
and txtbox.SelectionLength
properties. If you want to set caret to end try this:

I have done for
private void addOrRemoveProperty(View view, int property, boolean flag){
RelativeLayout.LayoutParams layoutParams = (RelativeLayout.LayoutParams) view.getLayoutParams();
if(flag){
layoutParams.addRule(property);
}else {
layoutParams.removeRule(property);
}
view.setLayoutParams(layoutParams);
}
How to call method:
centerInParent - true
addOrRemoveProperty(mView, RelativeLayout.CENTER_IN_PARENT, true);
centerInParent - false
addOrRemoveProperty(mView, RelativeLayout.CENTER_IN_PARENT, false);
centerHorizontal - true
addOrRemoveProperty(mView, RelativeLayout.CENTER_HORIZONTAL, true);
centerHorizontal - false
addOrRemoveProperty(mView, RelativeLayout.CENTER_HORIZONTAL, false);
centerVertical - true
addOrRemoveProperty(mView, RelativeLayout.CENTER_VERTICAL, true);
centerVertical - false
addOrRemoveProperty(mView, RelativeLayout.CENTER_VERTICAL, false);
Hope this would help you.
Socks4 is a very simple protocol to implement. You listen for the initial connection, connect to the host/port that was requested by the client, send the success code to the client then forward the outgoing and incoming streams across sockets.
If you go with HTTP you'll have to read and possibly set/remove some HTTP headers so that's a little more work.
If I remember correctly, SSL will work across HTTP and Socks proxies. For a HTTP proxy you implement the CONNECT verb, which works much like the socks4 as described above, then the client opens the SSL connection across the proxied tcp stream.
Here is my technique I'd like to share. Works well so long as your clr property types are sql equivalent types eg. bool -> bit, long -> bigint, string -> nchar/char/varchar/nvarchar, decimal -> money
public void SaveTransaction(Transaction transaction)

foreach (var prop in transaction.GetType().GetProperties(BindingFlags.Public | BindingFlags.Instance))
cmd.Parameters.AddWithValue("@" + prop.Name, prop.GetValue(transaction, null));
con.Open();

How about just using str_replace
function, if you just want to "Add Classes":
<?php
echo str_replace( '<li class="', '<li class="myclass ',
wp_nav_menu(
array(
'theme_location' => 'main_menu',
'container' => false,
'items_wrap' => '<ul>%3$s</ul>',
'depth' => 1,
'echo' => false
)
)
);
?>
Tough it is a quick fix for one-level menus or the menus that you want to add Classes to all of <li>
elements and is not recommended for more complex menus
Is there any equivalent for the truststore? How can I view the trusted certificates?
Yes there is.The exact same command since keystore and truststore differ only in what they store i.e. private key or signed public key (certificate)
No other difference
What I can think of is to stretch either width or height and let it resize in ratio-aspect. There will be some white space on the sides. Something like how a Wide screen displays a resolution of 1024x768.
You can list the tags on remote repository with ls-remote
, and then check if it's there. Supposing the remote reference name is origin
in the following.
git ls-remote --tags origin
And you can list tags local with tag
.
git tag
You can compare the results manually or in script.

The best solution is just not to use anonymous classes.
public class Test
{
class DummyInterfaceImplementor : IDummyInterface
{
public string A { get; set; }
public string B { get; set; }
}
public void WillThisWork()
{
var source = new DummySource[0];
var values = from value in source
select new DummyInterfaceImplementor()
{
A = value.A,
B = value.C + "_" + value.D
};
DoSomethingWithDummyInterface(values.Cast<IDummyInterface>());
}
public void DoSomethingWithDummyInterface(IEnumerable<IDummyInterface> values)
{
foreach (var value in values)
{
Console.WriteLine("A = '{0}', B = '{1}'", value.A, value.B);
}
}
}
Note that you need to cast the result of the query to the type of the interface. There might be a better way to do it, but I couldn't find it.
Exceptions bubble up the stack. If a caller calls a method that throws a checked exception, like IOException, it must also either catch the exception, or itself throw it.
In the case of the first block:
filecontent()
{
setGUI();
setRegister();
showfile();
setTitle("FileData");
setVisible(true);
setSize(300, 300);
/*
addWindowListener(new WindowAdapter()
{
public void windowClosing(WindowEvent we)
{
System.exit(0);
}
});
*/
}
You would have to include a try catch block:
filecontent()
{
setGUI();
setRegister();
try {
showfile();
}
catch (IOException e) {
// Do something here
}
setTitle("FileData");
setVisible(true);
setSize(300, 300);
/*
addWindowListener(new WindowAdapter()
{
public void windowClosing(WindowEvent we)
{
System.exit(0);
}
});
*/
}
In the case of the second:
public void actionPerformed(ActionEvent ae)
{
if (ae.getSource() == submit)
{
showfile();
}
}
You cannot throw IOException from this method as its signature is determined by the interface, so you must catch the exception within:
public void actionPerformed(ActionEvent ae)
{
if(ae.getSource()==submit)
{
try {
showfile();
}
catch (IOException e) {
// Do something here
}
}
}
Remember, the showFile() method is throwing the exception; that's what the "throws" keyword indicates that the method may throw that exception. If the showFile() method is throwing, then whatever code calls that method must catch, or themselves throw the exception explicitly by including the same throws IOException addition to the method signature, if it's permitted.
If the method is overriding a method signature defined in an interface or superclass that does not also declare that the method may throw that exception, you cannot declare it to throw an exception.
I ran into this issue with a Grails install.
The problem was my JAVA_HOME was c:\sun\jdk\
and my PATH has %JAVA_HOME%bin
I changed it to: JAVA_HOME= "c:\sun\jdk" and PATH="%JAVA_HOME%\bin"
It worked after that.
A general purpose way is to coerce the collation to DATABASE_DEFAULT. This removes hardcoding the collation name which could change.
It's also useful for temp table and table variables, and where you may not know the server collation (eg you are a vendor placing your system on the customer's server)
select
sone_field collate DATABASE_DEFAULT
from
table_1
inner join
table_2 on table_1.field collate DATABASE_DEFAULT = table_2.field

Dupx
Dupx is a simple *nix utility to redirect standard output/input/error of an already running process.
Motivation
I've often found myself in a situation where a process I started on a remote system via SSH takes much longer than I had anticipated. I need to break the SSH connection, but if I do so, the process will die if it tries to write something on stdout/error of a broken pipe. I wish I could suspend the process with ^Z and then do a
bg %1 >/tmp/stdout 2>/tmp/stderr
Unfortunately this will not work (in shells I know).
I was getting the following message:
Could not open/create prefs root node Software\JavaSoft\Prefs at root 0x80000002
and it was gone after creating one of these registry keys, mine is 64 bit so I tried only that.
32 bit Windows
HKEY_LOCAL_MACHINE\Software\JavaSoft\Prefs
64 bit Windows
HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\JavaSoft\Prefs
I solved this with Access options.
Go to the Office Button --> Access Options --> Trust Center --> Trust Center Settings Button --> Message Bar
In the right hand pane I selected the radio button "Show the message bar in all applications when content has been blocked."
Closed Access, reopened the database and got the warning for blocked content again.
Things to Make sure
Download Oracle Client from Download From here
Paste it in C:\instantclient_12_1
Easiest solution is to create the column using the correct data type: DATE
For example:
Create table:
create table test_date (mydate date);
Insert row:
insert into test_date values (to_date('01-01-2011','dd-mm-yyyy'));
To get the month and year, do as follows:
select to_char(mydate, 'MM-YYYY') from test_date;
Your result will be as follows: 01-2011
Another cool function to use is "EXTRACT"
select extract(year from mydate) from test_date;
This will return: 2011
chmod +w <directory>
or chmod a+w <directory>
- Write permission for user, group and others
chmod u+w <directory>
- Write permission for user
chmod g+w <directory>
- Write permission for group
chmod o+w <directory>
- Write permission for others
For that, you can use default difflib in python
from difflib import SequenceMatcher
def similar(a, b):
return SequenceMatcher(None, a, b).ratio()
then call similar() as
similar(string1, string2)
it will return compare as ,ratio >= threshold to get match result
Most of the given solutions using the mouseup
or contextmenu
events fire every time the right mouse button goes up, but they don't check wether it was down before.
If you are looking for a true right click event, which only fires when the mouse button has been pressed and released within the same element, then you should use the auxclick
event. Since this fires for every none-primary mouse button you should also filter other events by checking the button
property.
window.addEventListener("auxclick", (event) => {
if (event.button === 2) alert("Right click");
});
_x000D_
You can also create your own right click event by adding the following code to the start of your JavaScript:
{
const rightClickEvent = new CustomEvent('rightclick', { bubbles: true });
window.addEventListener("auxclick", (event) => {
if (event.button === 2) {
event.target.dispatchEvent(rightClickEvent);
}
});
}
You can then listen for right click events via the addEventListener
method like so:
your_element.addEventListener("rightclick", your_function);
Read more about the auxclick
event on MDN.
Or you can try using git revert http://www.kernel.org/pub/software/scm/git/docs/git-revert.html. I think something like git revert HEAD~1 -m 1
will revert your last commit (if it's still the last commit).

I had the same issue... Installing the EF from Package Manager Console worked for me
the command was: Install-Package EntityFramework
Thanks,Bruno for giving me heads up on Common Name and Subject Alternative Name. As we figured out certificate was generated with CN with DNS name of network and asked for regeneration of new certificate with Subject Alternative Name entry i.e. san=ip:10.0.0.1. which is the actual solution.
But, we managed to find out a workaround with which we can able to run on development phase. Just add a static block in the class from which we are making ssl connection.
static {
HttpsURLConnection.setDefaultHostnameVerifier(new HostnameVerifier()
{
public boolean verify(String hostname, SSLSession session)
{
// ip address of the service URL(like.23.28.244.244)
if (hostname.equals("23.28.244.244"))
return true;
return false;
}
});
}
If you happen to be using Java 8, there is a much slicker way of achieving the same result:
static {
HttpsURLConnection.setDefaultHostnameVerifier((hostname, session) -> hostname.equals("127.0.0.1"));
}
chmod +x openfire
worked for me. It adds execution permission to the openfire folder.
I found the solution:
function onClick(e) {alert(this.getLatLng());}
used the method getLatLng() of the marker
I wrote extension method
public static string ToMatrixString<T>(this T[,] matrix, string delimiter = "\t")
{
var s = new StringBuilder();
for (var i = 0; i < matrix.GetLength(0); i++)
{
for (var j = 0; j < matrix.GetLength(1); j++)
{
s.Append(matrix[i, j]).Append(delimiter);
}
s.AppendLine();
}
return s.ToString();
}
To use just call the method
results.ToMatrixString();
This is not an elegant solution, but what does seem to work is saving to XLSX and then importing it back. The other solutions on this page did not work for me, unsure why.

Can you get round this by calling System.load() programmatically to load your native library? This method (unlike System.loadLibrary()) allows you to specify an absolute path.
You need only to write:
GRANT DBA TO NewDBA;
Because this already makes the user a DB Administrator
In my project I usually use an external function that "filters" data retrieved with mysql_fetch_assoc
.
You can rename fields in your table so that is intuitive to understand which data type is stored.
For example, you can add a special suffix to each numeric field:
if userid
is an INT(11)
you can rename it userid_i
or if it is an UNSIGNED INT(11)
you can rename userid_u
.
At this point, you can write a simple PHP function that receive as input the associative array (retrieved with mysql_fetch_assoc
), and apply casting to the "value" stored with those special "keys".
First, you need to obtain the public certificate from the server you're trying to connect to. That can be done in a variety of ways, such as contacting the server admin and asking for it, using OpenSSL to download it, or, since this appears to be an HTTP server, connecting to it with any browser, viewing the page's security info, and saving a copy of the certificate. (Google should be able to tell you exactly what to do for your specific browser.)
Now that you have the certificate saved in a file, you need to add it to your JVM's trust store. At $JAVA_HOME/jre/lib/security/
for JREs or $JAVA_HOME/lib/security
for JDKs, there's a file named cacerts
, which comes with Java and contains the public certificates of the well-known Certifying Authorities. To import the new cert, run keytool as a user who has permission to write to cacerts:
keytool -import -file <the cert file> -alias <some meaningful name> -keystore <path to cacerts file>
It will most likely ask you for a password. The default password as shipped with Java is changeit
. Almost nobody changes it. After you complete these relatively simple steps, you'll be communicating securely and with the assurance that you're talking to the right server and only the right server (as long as they don't lose their private key).
I'd suggest a different approach to this question. Maybe it's not the most efficient one, but I think it's the easiest to apply and requires very little code. Writing the next code in your first activity (log in activity, in my case) won't let the user go back to previously launched activities after logging out.
@Override
public void onBackPressed() {
// disable going back to the MainActivity
moveTaskToBack(true);
}
I'm assuming that LoginActivity is finished just after the user logs in, so that he can't go back to it later by pressing the back button. Instead, the user must press a log out button inside the app in order to log out properly. What this log out button would implement is a simple intent as follows:
Intent intent = new Intent(this, LoginActivity.class);
startActivity(intent);
finish();
All suggestions are welcome.
If you are using it with Hibernate, you'll have to explicitly define the annotation CascadeType.DELETE_ORPHAN
, which can be used in conjunction with JPA CascadeType.ALL
.
If you don't plan to use Hibernate, you'll have to explicitly first delete the child elements and then delete the main record to avoid any orphan records.

The best way is to copy all the files and folders inside a directory on your local file system by: docker cp [OPTIONS] CONTAINER:SRC_PATH DEST_PATH
SRC_PATH
is on container
DEST_PATH

Then do docker-compose down
attach a volume to the same DEST_PATH
and run Docker containers by using docker-compose up -d
Add volume by following in docker-compose.yml
volumes:

The postscript()
device allows creation of EPS, but only if you change some of the default values. Read ?postscript
for the details.
Here is an example:
postscript("foo.eps", horizontal = FALSE, onefile = FALSE, paper = "special")
plot(1:10)
dev.off()
One way to do this is to pull your field into the rows section of the pivot table from the Filter section. Then group the values that you want to keep into a group, using the group option on the menu. After that is completed, drag your field back into the Filters section. The grouping will remain and you can check or uncheck one box to remove lots of values.
Yes there is:
ARRAY=()
ARRAY+=('foo')
ARRAY+=('bar')
In the context where an assignment statement is assigning a value to a shell variable or array index (see Arrays), the ‘+=’ operator can be used to append to or add to the variable's previous value.
Use the Key
keyword in your select will work, like below.
product.Select(m => new {Key m.CategoryId, Key m.CategoryName}).Distinct();
I realize this is bringing up an old thread but figured it might help some people. I generally code in VB.NET when working with .NET so Key
may translate differently into C#.
Whenever you print any instance of your class, the default
toString
implementation of Object
class is called, which returns the representation that you are getting.
It contains two parts: - Type
and Hashcode
So, in student.Student@82701e that you get as output ->
student.Student
is the Type
, and82701e
is the HashCode
So, you need to override a toString
method in your Student
class to get required String representation
: -
@Override
public String toString() {
return "Student No: " + this.getStudentNo() +
", Student Name: " + this.getStudentName();
}
So, when from your main
class, you print your ArrayList
, it will invoke the toString
method for each instance, that you overrided
rather than the one in Object
class: -
List<Student> students = new ArrayList();
// You can directly print your ArrayList
System.out.println(students);
// Or, iterate through it to print each instance
for(Student student: students) {
System.out.println(student); // Will invoke overrided `toString()` method
}
In both the above cases, the toString
method overrided in Student
class will be invoked and appropriate representation of each instance will be printed.
You can use {!! $text !!} for render HTML code in Laravel
{!! $text !!}
If you use
{{ $text }}
It will not render HTML code and print as a string.
One of my favorite parts about registers is using them as macros!
Let's say you are dealing with a tab-delimited value file as such:
ID Df %Dev Lambda
1 0 0.000000 0.313682
2 1 0.023113 0.304332
3 1 0.044869 0.295261
4 1 0.065347 0.286460
5 1 0.084623 0.277922
6 1 0.102767 0.269638
7 1 0.119845 0.261601
Now you decide that you need to add a percentage sign at the end of the %Dev field (starting from 2nd line). We'll make a simple macro in the (arbitrarily selected) m
register as follows:
Press: qm
: To start recording macro under m
register.
EE
: Go to the end of the 3rd column.
a
: Insert mode to append to the end of this column.
%
: Type the percent sign we want to add.
<ESC>
: Get back into command mode.
j0
: Go to beginning of next line.
q
: Stop recording macro
We can now just type @m
to run this macro on the current line. Furthermore, we can type @@
to repeat, or 100@m
to do this 100 times! Life's looking pretty good.
At this point you should be saying, "But what does this have to do with registers?"
Excellent point. Let's investigate what is in the contents of the m
register by typing "mp
. We then get the following:
EEa%<ESC>j0
At first this looks like you accidentally opened a binary file in notepad, but upon second glance, it's the exact sequence of characters in our macro!
You are a curious person, so let's do something interesting and edit this line of text to insert a !
instead of boring old %
.
EEa!<ESC>j0
Then let's yank this into the n
register by typing B"nyE
. Then, just for kicks, let's run the n
macro on a line of our data using @n
....
It added a !
.
Essentially, running a macro is like pressing the exact sequence of keys in that macro's register. If that isn't a cool register trick, I'll eat my hat.
The syntax you're after is possible with a little helper function that converts a Runnable
into Action<Void, Void>
(you can place it in Action
for example):
public static Action<Void, Void> action(Runnable runnable) {
return (v) -> {
runnable.run();
return null;
};
}
// Somewhere else in your code
Action<Void, Void> action = action(() -> System.out.println("foo"));

$var ??= '';
PHP 7.0+; with the null coalescing operator
$var = $var ?? '';

or
!isset($var) && $var = '';
Use this
if let navVCsCount = navigationController?.viewControllers.count {
navigationController?.viewControllers.removeSubrange(Range(2..<navVCsCount - 1))
}
It will take care of ViewControllers of navigationController. viewControllers and also a navigationItems stacked in navigationBar.
Note: Be sure to call it at least after viewDidAppear
You can use following:
angular.element(domElement).scope()
to get the current scope for the element
angular.element(domElement).injector()
to get the current app injector
angular.element(domElement).controller()
to get a hold of the ng-controller instance.
Hope that might help
I dont think you need to use jQuery at all, just simple JavaScript...
Save the date as a string:
dte = fecha.value;//2014-01-06
Split the string to get the day, month & year values...
dteSplit = dte.split("-");
yr = dteSplit[0][2] + dteSplit[0][3]; //special yr format, take last 2 digits
month = dteSplit[1];
day = dteSplit[2];
Rejoin into final date string:
finalDate = month+"-"+day+"-"+year
An one-liner that works with alternative libraries to jQuery:
$('p').filter((i, p) => $(p).text().trim() === "hello").css('font-weight', 'bold');
And this is the equivalent to a jQuery's a:contains("pattern")
selector:
var res = $('a').filter((i, a) => $(a).text().match(/pattern/));
Push down the whole button. I suggest this it is looking nice in button.
#button:active {
position: relative;
top: 1px;
}
if you only want to push text increase top-padding and decrease bottom padding. You can also use line-height.
In c# you can simply say:
if (myObj is Car) {
}
In the terminal, you are running the node application and it is running your script. That is a very different execution environment than directly running your script in the browser. While the Javascript language is largely the same (both V8 if you're running the Chrome browser), the rest of the execution environment such as libraries available are not the same.
node.js is a server-side Javascript execution environment that combines the V8 Javascript engine with a bunch of server-side libraries. require()
is one such feature that node.js adds to the environment. So, when you run node in the terminal, you are running an environment that contains require()
.
require()
is not a feature that is built into the browser. That is a specific feature of node.js, not of a browser. So, when you try to have the browser run your script, it does not have require()
.
There are ways to run some forms of node.js code in a browser (but not all). For example, you can get browser substitutes for require()
that work similarly (though not identically).
But, you won't be running a web server in your browser as that is not something the browser has the capability to do.
You may be interested in browserify which lets you use node-style modules in a browser using require()
statements.

Most likely you're looking for the ToCharArray() method. However, you will need to do slightly more work if a string[]
is required, as you noted in your post.
string str = "this is a test.";
char[] charArray = str.ToCharArray();
string[] strArray = str.Select(x => x.ToString()).ToArray();
Edit: If you're worried about the conciseness of the conversion, I suggest you make it into an extension method.
public static class StringExtensions
{
public static string[] ToStringArray(this string s)
{
if (string.IsNullOrEmpty(s))
return null;
return s.Select(x => x.ToString()).ToArray();
}
}
iList.SelectMany(x => x).ToArray()
Not a solution / workaround but perhaps an answer to the question 'what could be the problem':
Gitlab and the 'jetbrains built in ssh library' do not work well together. The library wants to use SHA1 based key exchange algorithm where gitlab (default) only allows SHA2 based key exchange algorithm's.
This was reported for at least TeamCity (https://youtrack.jetbrains.com/issue/TW-47704).
The fact that it also might be the cause for your pull/push problem in IntelliJ, and also my push-problem in PhpStorm is based on the ASSUMPTION jetbrains use the same 'built in library' for all their software.
Not yet, but the New NIO (JSR 203) will have support for these common operations.
In the meantime, there are a few things to keep in mind.
File.renameTo generally works only on the same file system volume. I think of this as the equivalent to a "mv" command. Use it if you can, but for general copy and move support, you'll need to have a fallback.
When a rename doesn't work you will need to actually copy the file (deleting the original with File.delete if it's a "move" operation). To do this with the greatest efficiency, use the FileChannel.transferTo or FileChannel.transferFrom methods. The implementation is platform specific, but in general, when copying from one file to another, implementations avoid transporting data back and forth between kernel and user space, yielding a big boost in efficiency.
Using pretty much the same approach as used by Burnash, for the final result you can use ...
=regexextract(A1,"[0-9]+")+A2
where A1 houses the string with text and number and A2 houses the date of interest
You need a bit more information so that the browser knows what you want. For instance, the children of the container need to be told "how" to flex.
I've added #wrapper > * { flex: 1; margin: auto; }
to your CSS and changed inline-flex
to flex
, and you can see how the elements now space themselves out evenly on the page.
You are getting Floating point exception because Number % i
, when i
is 0
:
int Is_Prime( int Number ){
int i ;
for( i = 0 ; i < Number / 2 ; i++ ){
if( Number % i != 0 ) return -1 ;
}
return Number ;
}
Just start the loop at i = 2
. Since i = 1
in Number % i
it always be equal to zero, since Number is a int.
With different domains, it is not possible to call methods or access the iframe's content document directly.
You have to use cross-document messaging.
For example in the top window:
myIframe.contentWindow.postMessage('hello', '*');
and in the iframe:
window.onmessage = function(e){
if (e.data == 'hello') {
alert('It works!');
}
};
If you are posting message from iframe to parent window
window.top.postMessage('hello', '*')
If your file is in the different package structure and you want to call it from a different package, then you can call it in that fashion:
Let's say you have following package structure in your python project:
in - com.my.func.DifferentFunction
python file you have some function, like:
def add(arg1, arg2):
return arg1 + arg2
def sub(arg1, arg2) :
return arg1 - arg2
def mul(arg1, arg2) :
return arg1 * arg2
And you want to call different functions from Example3.py
, then following way you can do it:
Define import statement in Example3.py
- file for import all function
from com.my.func.DifferentFunction import *
or define each function name which you want to import
from com.my.func.DifferentFunction import add, sub, mul
Then in Example3.py
you can call function for execute:
num1 = 20
num2 = 10
print("\n add : ", add(num1,num2))
print("\n sub : ", sub(num1,num2))
print("\n mul : ", mul(num1,num2))
Output:
add : 30
sub : 10
mul : 200
There is an object serialization module, with the serialize function you can serialize any object.
Here is my example:
private List<int> m_machinePorts = new List<int>();
public List<int> machinePorts
{
get { return m_machinePorts; }
}
Init()
{
// Custom function to get available ethernet ports
List<int> localEnetPorts = _Globals.GetAvailableEthernetPorts();
// Custome function to get available serial ports
List<int> localPorts = _Globals.GetAvailableSerialPorts();
// Build Available port list
m_machinePorts.AddRange(localEnetPorts);
m_machinePorts.AddRange(localPorts);
}
Assertions are a systematic way to check that the internal state of a program is as the programmer expected, with the goal of catching bugs. See the example below.
>>> number = input('Enter a positive number:')
Enter a positive number:-1
>>> assert (number > 0), 'Only positive numbers are allowed!'
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
AssertionError: Only positive numbers are allowed!
>>>
For a line-by-line delta measurement, try gnonom.
It is a command line utility, a bit like moreutils's ts, to prepend timestamp information to the standard output of another command. Useful for long-running processes where you'd like a historical record of what's taking so long.
Piping anything to gnomon will prepend a timestamp to each line, indicating how long that line was the last line in the buffer--that is, how long it took the next line to appear. By default, gnomon will display the seconds elapsed between each line, but that is configurable.
That tool is part of the setuptools (now called Distribute) package. Install Distribute. Of course you'll have to fetch that one manually.

The method you're using to read the http body response returns a byte slice:
func ReadAll(r io.Reader) ([]byte, error)
You can convert []byte
to a string by using
body, err := ioutil.ReadAll(resp.Body)
bodyString := string(body)
A log of your commands may be available in your shell history.
history
If seeing the list of executed commands fly by isn't for you, export the list into a file.
history > path/to/file
You can restrict the exported dump to only show commands with "git" in them by piping it with grep
history | grep "git " > path/to/file
The history may contain lines formatted as such
518 git status -s
519 git commit -am "injects sriracha to all toppings, as required"
Using the number you can re-execute the command with an exclamation mark
$ !518
git status -s
You can try this:
$(".myclass").mouseover(function() {
$(this).find(" > div").css("background-color","red");
}).mouseout(function() {
$(this).find(" > div").css("background-color","transparent");
});
As everyone noticed: you can't. But you can create a obj and assign every var you declare to that obj. That way you can easily check out your vars:
var v = {}; //put everything here
var f = function(a, b){//do something
}; v.f = f; //make's easy to debug
var a = [1,2,3];
v.a = a;
var x = 'x';
v.x = x; //so on...
console.log(v); //it's all there
For those that haven't found a working solution above, I believe I have a working one. My specific use case was that I wanted to scroll to the bottom of a specific div - in my case a chatbox - whenever a new message was added to the array.
const container = this.$el.querySelector('#messagesCardContent');
this.$nextTick(() => {
// DOM updated
container.scrollTop = container.scrollHeight;
});
I have to use nextTick as we need to wait for the dom to update from the data change before doing the scroll!
I just put the above code in a watcher for the messages array, like so:
messages: {
handler() {
// this scrolls the messages to the bottom on loading data
const container = this.$el.querySelector('#messagesCard');
this.$nextTick(() => {
// DOM updated
container.scrollTop = container.scrollHeight;
});
},
deep: true,
},
Luke's description of the function results in these scenarios seems to be right on. I only wish to understand the root cause and the PowerShell product team would do something about the behavior. It seems to be quite common and has cost me too much debugging time.
To get around this issue I've been using global variables rather than returning and using the value from the function call.
Here's another question on the use of global variables: Setting a global PowerShell variable from a function where the global variable name is a variable passed to the function
You can do this a couple of ways.
Via the "Solution Explorer"
Via the "Package Manager Console"
Install-Package Newtonsoft.Json
For more info on how to use the "Package Manager Console" check out the nuget docs.
I found another issue, for some reason if the extensions are cached in the local AppData folder, the XNA extensions never get loaded.
You need to remove the files extensionSdks.en-US.cache
and extensions.en-US.cache
from the %LocalAppData%\Microsoft\VisualStudio\11.0\Extensions
folder. These files are rebuilt the next time you launch
If you need access to the Visual Studio startup log to debug what's happening, run devenv.exe /log
command from the C:\Program Files (x86)\Microsoft Visual Studio 11.0\Common7\IDE
directory (assuming you are on a 64 bit machine). The log file generated is located here:
%AppData%\Microsoft\VisualStudio\11.0\ActivityLog.xml
There's a native DOM API that achieves this out of the box — getBoundingClientRect
:
document.querySelector("#whatever").getBoundingClientRect().right
From another perspective, files that both unicode and ascii encodings fail to read because they have a byte 0xc0
in them, seem to get read by iso-8859-1 properly. The caveat is that the file shouldn't have unicode characters in it of course.
I want to give an example which others haven't mentioned
* can also unpack a generator
An example from Python3 Document
x = [1, 2, 3]
y = [4, 5, 6]
unzip_x, unzip_y = zip(*zip(x, y))
unzip_x will be [1, 2, 3], unzip_y will be [4, 5, 6]
The zip() receives multiple iretable args, and return a generator.
zip(*zip(x,y)) -> zip((1, 4), (2, 5), (3, 6))
You want:
dir > a.txt 2>&1
The syntax 2>&1
will redirect 2
(stderr) to 1
(stdout). You can also hide messages by redirecting to NUL

In project.json add a dependency to:
"Microsoft.AspNetCore.HttpOverrides": "1.0.0"
In Startup.cs
, in the Configure()
method add:
app.UseForwardedHeaders(new ForwardedHeadersOptions
{
ForwardedHeaders = ForwardedHeaders.XForwardedFor |
ForwardedHeaders.XForwardedProto
});
And, of course:
using Microsoft.AspNetCore.HttpOverrides;
Then, I could get the ip by using:
Request.HttpContext.Connection.RemoteIpAddress
In my case, when debugging in VS I got always IpV6 localhost, but when deployed on an IIS I got always the remote IP.
Some useful links: How do I get client IP address in ASP.NET CORE? and RemoteIpAddress is always null
The ::1
is maybe because of:
Connections termination at IIS, which then forwards to Kestrel, the v.next web server, so connections to the web server are indeed from localhost. (https://stackoverflow.com/a/35442401/5326387)
this may be a simpler approach:
(DesiredFigure).get_figure().savefig('figure_name.png')
i.e.
dfcorr.hist(bins=50).get_figure().savefig('correlation_histogram.png')
I guess I misunderstood what was being asked. Re-re-reading, it looks like Tim's answer is what you want. Let me just add this, however: if you want to catch an exception from open
, then open
has to be wrapped in a try
. If the call to open
is in the header of a with
, then the with
has to be in a try
to catch the exception. There's no way around that.
So the answer is either: "Tim's way" or "No, you're doing it correctly.".
Previous unhelpful answer to which all the comments refer:
import os
if os.path.exists(fName):
with open(fName, 'rb') as f:
try:
# do stuff
except : # whatever reader errors you care about
# handle error
Your JFrame default close action can be set to "DISPOSE_ON_CLOSE
" instead of EXIT_ON_CLOSE
(why people keep using EXIT_ON_CLOSE is beyond me).
If you have any undisposed windows or non-daemon threads, your application will not terminate. This should be considered a error (and solving it with System.exit is a very bad idea).
The most common culprits are java.util.Timer and a custom Thread you've created. Both should be set to daemon or must be explicitly killed.
If you want to check for all active frames, you can use Frame.getFrames()
. If all Windows/Frames are disposed of, then use a debugger to check for any non-daemon threads that are still running.
$eval
and $parse
don't evaluate JavaScript; they evaluate AngularJS expressions. The linked documentation explains the differences between expressions and JavaScript.
Q: What exactly is $eval doing? Why does it need its own mini parsing language?
From the docs:
Expressions are JavaScript-like code snippets that are usually placed in bindings such as {{ expression }}. Expressions are processed by $parse service.
It's a JavaScript-like mini-language that limits what you can run (e.g. no control flow statements, excepting the ternary operator) as well as adds some AngularJS goodness (e.g. filters).
Q: Why isn't plain old javascript "eval" being used?
Because it's not actually evaluating JavaScript. As the docs say:
If ... you do want to run arbitrary JavaScript code, you should make it a controller method and call the method. If you want to eval() an angular expression from JavaScript, use the $eval() method.
The docs linked to above have a lot more information.
Yes, you can use GT for free. See the post with explanation. And look at repo on GitHub.

As you say, there are some important differences between ToUpper and ToLower, and only one is dependably accurate when you're trying to do case insensitive equality checks.
Ideally, the best way to do a case-insensitive equality check would be:
String.Equals(row.Name, "test", StringComparison.OrdinalIgnoreCase)
NOTE, HOWEVER that this does not work in this case! Therefore we are stuck with ToUpper
or ToLower
.
Note the OrdinalIgnoreCase to make it security-safe. But exactly the type of case (in)sensitive check you use depends on what your purposes is. But in general use Equals for equality checks and Compare when you're sorting, and then pick the right StringComparison for the job.
Michael Kaplan (a recognized authority on culture and character handling such as this) has relevant posts on ToUpper vs. ToLower:
He says "String.ToUpper – Use ToUpper rather than ToLower, and specify InvariantCulture in order to pick up OS casing rules"
You can use this to solve your problem:
private async void btn_Go_Click(object sender, RoutedEventArgs e)
{
HttpClient webClient = new HttpClient();
Uri uri = new Uri("http://www.school-link.net/webservice/get_student/?id=" + txtVCode.Text);
HttpResponseMessage response = await webClient.GetAsync(uri);
var jsonString = await response.Content.ReadAsStringAsync();
var _Data = JsonConvert.DeserializeObject <List<Student>>(jsonString);
foreach (Student Student in _Data)
{
tb1.Text = Student.student_name;
}
}
You can create a a method and pass paramters to it and get the json as a response.
private JSONObject jsonResult(String Name,int id, String curriculum) throws JSONException {
JSONObject json = null;
json = new JSONObject("{\"" + "Name" + "\":" + "\"" + Name+ "\""
+ "," + "\"" + "Id" + "\":" + id + "," + "\"" + "Curriculum"
+ "\":" + "\"" + curriculum+ "\"" + "}");
return json;
}
I hope this will help you.
If you're using jackson, better to convert directly to ObjectNode.
//not including SerializationFeatures for brevity
static final ObjectMapper mapper = new ObjectMapper();
//pass it your payload
public static ObjectNode convObjToONode(Object o) {
StringWriter stringify = new StringWriter();
ObjectNode objToONode = null;
try {
mapper.writeValue(stringify, o);
objToONode = (ObjectNode) mapper.readTree(stringify.toString());
} catch (IOException e) {
e.printStackTrace();
}
System.out.println(objToONode);
return objToONode;
}
"How do I create an initial database ?"
You created a database when you installed XE. At some point the installation process prompted you to enter a password for the SYSTEM account. Use that to connect to the XE database using the SQL commandline on the application menu.
The XE documentation is online and pretty helpful. Find it here.
It's worth mentioning that 11g XE has several limitations, one of which is only one database per server. So using the pre-installed database is the sensible option.
It sounds like you are going to be storing the value that input field contains after the form is submitted, which means you are using a scripting language. I would use it instead of JavaScript as most scripting languages have better time/date formatting options. In PHP you could do something like this:
<input id="date" name="date" value="<?php echo date("M j, Y - g:i"); ?>"/>
Which would fill the field with "Jun 16, 2009 - 8:58"
You get the same exception when you pass the incorrect Entity object to the CrudRepository in the repository class.
public interface XYZRepository extends CrudRepository<IncorrectEntityClass, Long>
I would just do this in C++ with a text file and extract the tokens. Why? I am not a linux terminal expert like the others.
To set it up I would do this in Linux..
ffmpeg -i 2>&1 | grep "" > mytext.txt
and then run some C++ app to get the data needed. Maybe extract all the important values and reformat it for further processing by using tokens. I will just have to work on my own solution and people will just make fun of me because I am a linux newbie and I do not like scripting too much.
Note: This is an answer useful for Python's ElementTree standard library without using hardcoded namespaces.
To extract namespace's prefixes and URI from XML data you can use ElementTree.iterparse
function, parsing only namespace start events (start-ns):
>>> from io import StringIO
>>> from xml.etree import ElementTree
>>> my_schema = u'''<rdf:RDF xml:base="http://dbpedia.org/ontology/"
... xmlns:rdf="http://www.w3.org/1999/02/22-rdf-syntax-ns#"
... xmlns:owl="http://www.w3.org/2002/07/owl#"
... xmlns:xsd="http://www.w3.org/2001/XMLSchema#"
... xmlns:rdfs="http://www.w3.org/2000/01/rdf-schema#"
... xmlns="http://dbpedia.org/ontology/">
...
... <owl:Class rdf:about="http://dbpedia.org/ontology/BasketballLeague">
... <rdfs:label xml:lang="en">basketball league</rdfs:label>
... <rdfs:comment xml:lang="en">
... a group of sports teams that compete against each other
... in Basketball
... </rdfs:comment>
... </owl:Class>
...
... </rdf:RDF>'''
>>> my_namespaces = dict([
... node for _, node in ElementTree.iterparse(
... StringIO(my_schema), events=['start-ns']
... )
... ])
>>> from pprint import pprint
>>> pprint(my_namespaces)
{'': 'http://dbpedia.org/ontology/',
'owl': 'http://www.w3.org/2002/07/owl#',
'rdf': 'http://www.w3.org/1999/02/22-rdf-syntax-ns#',
'rdfs': 'http://www.w3.org/2000/01/rdf-schema#',
'xsd': 'http://www.w3.org/2001/XMLSchema#'}
Then the dictionary can be passed as argument to the search functions:
root.findall('owl:Class', my_namespaces)
You can use produces to indicate the type of the response you are sending from the controller. This "produces" keyword will be most useful in ajax request and was very helpful in my project
@RequestMapping(value = "/aURLMapping.htm", method = RequestMethod.GET, produces = "text/html; charset=utf-8")
public @ResponseBody String getMobileData() {
}
A specification (blueprint) about how to make an OS compatible with late UNIX OS (may God bless him!). This is why macOS and GNU/Linux have very similar terminal command lines, GUI's, libraries, etc. Because they both were designed according to POSIX blueprint.
POSIX does not tell engineers and programmers how to code but what to code.
Since Docker 1.5 you can now expose a range of ports to other linked containers using:
The Dockerfile EXPOSE command:
EXPOSE 7000-8000
or The Docker run command:
docker run --expose=7000-8000
Or instead you can publish a range of ports to the host machine via Docker run command:
docker run -p 7000-8000:7000-8000
I tried everything and what worked best for my solution was to always have the vertical scrollbar show, and then add some negative margin to hide it.
This worked for IE11, FF60.9 and Chrome 80
body {
-ms-overflow-style: none; /** IE11 */
overflow-y: scroll;
overflow-x: hidden;
margin-right: -20px;
}
Depending on your usage pattern, you might just like to use only. We use the TDD style; it looks like this:
test.only('Date part of valid Partition Key', function (done) {
//...
}
Only this test will run from all the files/suites.
For me WORKSPACE was a valid property of the pipeline itself. So when I handed over this
to a Groovy method as parameter context
from the pipeline script itself, I was able to access the correct value using "... ${context.WORKSPACE} ..."

A more modern version:
function arraysEqual(a, b) {
a = Array.isArray(a) ? a : [];
b = Array.isArray(b) ? b : [];
return a.length === b.length && a.every((el, ix) => el === b[ix]);
}
Coercing non-array arguments to empty arrays stops a.every()
from exploding.
If you just want to see if the arrays have the same set of elements then you can use Array.includes()
:
function arraysContainSame(a, b) {
a = Array.isArray(a) ? a : [];
b = Array.isArray(b) ? b : [];
return a.length === b.length && a.every(el => b.includes(el));
}

new Map([
["1", ["test"]],
["2", ["test2"]]

Put this .gitignore
into the folder, then git add .gitignore
.
*
*/
!.gitignore
The *
line tells git to ignore all files in the folder, but !.gitignore
tells git to still include the .gitignore
file. This way, your local repository and any other clones of the repository all get both the empty folder and the .gitignore
it needs.
Edit: May be obvious but also add */
to the .gitignore
to also ignore subfolders.
In the above given code

One thing in combination of PHP and Javsacript is you can not assign javascript value to PHP value. You can assign PHP value to javascript variable.

Here is the latest documentation:
I found that HotSpot lists all the VM arguments in the management bean except for -client and -server. Thus, if you infer the -client/-server argument from the VM name and add this to the runtime management bean's list, you get the full list of arguments.
Here's the SSCCE:
import java.util.*;
import java.lang.management.ManagementFactory;
class main {
public static void main(final String[] args) {
System.out.println(fullVMArguments());
}
static String fullVMArguments() {
String name = javaVmName();
return (contains(name, "Server") ? "-server "
: contains(name, "Client") ? "-client " : "")
+ joinWithSpace(vmArguments());
}
static List<String> vmArguments() {
return ManagementFactory.getRuntimeMXBean().getInputArguments();
}
static boolean contains(String s, String b) {
return s != null && s.indexOf(b) >= 0;
}
static String javaVmName() {
return System.getProperty("java.vm.name");
}
static String joinWithSpace(Collection<String> c) {
return join(" ", c);
}
public static String join(String glue, Iterable<String> strings) {
if (strings == null) return "";
StringBuilder buf = new StringBuilder();
Iterator<String> i = strings.iterator();
if (i.hasNext()) {
buf.append(i.next());
while (i.hasNext())
buf.append(glue).append(i.next());
}
return buf.toString();
}
}
Could be made shorter if you want the arguments in a List<String>
.
Final note: We might also want to extend this to handle the rare case of having spaces within command line arguments.
Mike Nereson has this to say on his blog at:
http://blog.codehangover.com/load-multiple-contexts-into-spring/
There are a couple of ways to do this.
1. web.xml contextConfigLocation
Your first option is to load them all into your Web application context via the ContextConfigLocation element. You’re already going to have your primary applicationContext here, assuming you’re writing a web application. All you need to do is put some white space between the declaration of the next context.
<context-param> <param-name> contextConfigLocation </param-name> <param-value> applicationContext1.xml applicationContext2.xml </param-value> </context-param> <listener> <listener-class> org.springframework.web.context.ContextLoaderListener </listener-class> </listener>
The above uses carriage returns. Alternatively, yo could just put in a space.
<context-param> <param-name> contextConfigLocation </param-name> <param-value> applicationContext1.xml applicationContext2.xml </param-value> </context-param> <listener> <listener-class> org.springframework.web.context.ContextLoaderListener </listener-class> </listener>
2. applicationContext.xml import resource
Your other option is to just add your primary applicationContext.xml to the web.xml and then use import statements in that primary context.
In
applicationContext.xml
you might have…<!-- hibernate configuration and mappings --> <import resource="applicationContext-hibernate.xml"/> <!-- ldap --> <import resource="applicationContext-ldap.xml"/> <!-- aspects --> <import resource="applicationContext-aspects.xml"/>
Which strategy should you use?
1. I always prefer to load up via web.xml.
Because , this allows me to keep all contexts isolated from each other. With tests, we can load just the contexts that we need to run those tests. This makes development more modular too as components stay
loosely coupled
, so that in the future I can extract a package or vertical layer and move it to its own module.2. If you are loading contexts into a
non-web application
, I would use theimport
resource.
from s in db.Services
join sa in db.ServiceAssignments on s.Id equals sa.ServiceId
where sa.LocationId == 1
select s
Where db
is your DbContext
. Generated query will look like (sample for EF6):
SELECT [Extent1].[Id] AS [Id]
-- other fields from Services table
FROM [dbo].[Services] AS [Extent1]
INNER JOIN [dbo].[ServiceAssignments] AS [Extent2]
ON [Extent1].[Id] = [Extent2].[ServiceId]
WHERE [Extent2].[LocationId] = 1
If you want to refer to names from the header rather than column numbers, you can use something like this:
fname <- "test.csv"
headset <- read.csv(fname, header = TRUE, nrows = 10)
classes <- sapply(headset, class)
classes[names(classes) %in% c("time")] <- "character"
dataset <- read.csv(fname, header = TRUE, colClasses = classes)
Through discourse it's clear that the problem lies in using VS2010 to write the query, as it uses the canonical CONCAT()
function which is limited to 2 parameters. There's probably a way to change that, but I'm not aware of it.
An alternative:
SELECT '1'+'2'+'3'
This approach requires non-string values to be cast/converted to strings, as well as NULL
handling via ISNULL()
or COALESCE()
:
SELECT ISNULL(CAST(Col1 AS VARCHAR(50)),'')
+ COALESCE(CONVERT(VARCHAR(50),Col2),'')
What you're looking for is:
if($variable === NULL) {...}
Note the ===
.
When use ==
, as you did, PHP treats NULL, false, 0, the empty string, and empty arrays as equal.
In new Smarty it is:
<pre>
{var_dump($variable)}
</pre>
Can also invoke oShell.Exec in order to be able to read STDIN/STDOUT/STDERR responses. Perfect for error checking which it seems you're doing with your sanity .BAT.
It allows servlets to have multiple servlet mappings:
<servlet>
<servlet-name>Servlet1</servlet-name>
<servlet-path>foo.Servlet</servlet-path>
</servlet>
<servlet-mapping>
<servlet-name>Servlet1</servlet-name>
<url-pattern>/enroll</url-pattern>
</servlet-mapping>
<servlet-mapping>
<servlet-name>Servlet1</servlet-name>
<url-pattern>/pay</url-pattern>
</servlet-mapping>
<servlet-mapping>
<servlet-name>Servlet1</servlet-name>
<url-pattern>/bill</url-pattern>
</servlet-mapping>
It allows filters to be mapped on the particular servlet:
<filter-mapping>
<filter-name>Filter1</filter-name>
<servlet-name>Servlet1</servlet-name>
</filter-mapping>
Your proposal would support neither of them. Note that the web.xml
is read and parsed only once during application's startup, not on every HTTP request as you seem to think.
Since Servlet 3.0, there's the @WebServlet
annotation which minimizes this boilerplate:
@WebServlet("/enroll")
public class Servlet1 extends HttpServlet {
This sounds more like you want a tooltip for the link selected. There are many jQuery tooltips, try out jQuery qTip. It has a lot of options and is easy to change the styles.
Otherwise if you want to do this yourself you can use the jQuery .position()
. More info about .position()
is on http://api.jquery.com/position/
$("#element").position();
will return the current position of an element relative to the offset parent.
There is also the jQuery .offset(); which will return the position relative to the document.
At the beginning of stored procedure one should put SET XACT_ABORT ON to instruct Sql Server to automatically rollback transaction in case of error. If ommited or set to OFF one needs to test @@ERROR after each statement or use TRY ... CATCH rollback block.
What happens if you try the following?
Instead of your double REPLACE
statement, try:
REPLACE(IFNULL(ts.description, ''),'\r\n', '\n')
Also, I think it should be LINES TERMINATED BY '\r\n'
instead of just '\n'
You can use JavaScript Timing Events to call function after certain interval of time:
This shows the alert box after 3 seconds:
setInterval(function(){alert("Hello")},3000);
You can use two method of time event in javascript.i.e.
setInterval()
: executes a function, over and over again, at
specified time intervalssetTimeout()
: executes a function, once, after waiting a
specified number of millisecondsUsing Subversion with either the Apache module or svnserve. I've been able to perform operations as multiple users using --username
.
Each time you invoke a Subversion command as a 'new' user, your $HOME/.subversion/auth/<authentication-method>/
directory will have a new entry cached for that user (assuming you are able to authenticate with the correct password or authentication method for the server you are contacting as that particular user).
Vim mailing list says (re-formatted for better readability):
To change two vertically split windows to horizonally split
Ctrl-w t Ctrl-w K
Horizontally to vertically:
Ctrl-w t Ctrl-w H
Explanations:
Ctrl-w t makes the first (topleft) window current
Ctrl-w K moves the current window to full-width at the very top
Ctrl-w H moves the current window to full-height at far left
Note that the t is lowercase, and the K and H are uppercase.
Also, with only two windows, it seems like you can drop the Ctrl-w t part because if you're already in one of only two windows, what's the point of making it current?
A better way, use getParent()
from File
Class..
String a="/root/sdcard/Pictures/img0001.jpg"; // A valid file path
File file = new File(a);
String getDirectoryPath = file.getParent(); // Only return path if physical file exist else return null
http://developer.android.com/reference/java/io/File.html#getParent%28%29
Generally speaking:
all
and any
are functions that take some iterable and return True
, if
all()
, no values in the iterable are falsy;any()
, at least one value is truthy.A value x
is falsy iff bool(x) == False
.
A value x
is truthy iff bool(x) == True
.
Any non-booleans in the iterable will be fine — bool(x)
will coerce any x
according to these rules: 0
, 0.0
, None
, []
, ()
, []
, set()
, and other empty collections will yield False
, anything else True
. The docstring for bool
uses the terms 'true'/'false' for 'truthy'/'falsy', and True
/False
for the concrete boolean values.
In your specific code samples:
You misunderstood a little bit how these functions work. Hence, the following does something completely not what you thought:
if any(foobars) == big_foobar:
...because any(foobars)
would first be evaluated to either True
or False
, and then that boolean value would be compared to big_foobar
, which generally always gives you False
(unless big_foobar
coincidentally happened to be the same boolean value).
Note: the iterable can be a list, but it can also be a generator/generator expression (˜ lazily evaluated/generated list) or any other iterator.
What you want instead is:
if any(x == big_foobar for x in foobars):
which basically first constructs an iterable that yields a sequence of booleans—for each item in foobars
, it compares the item to big_foobar
and emits the resulting boolean into the resulting sequence:
tmp = (x == big_foobar for x in foobars)
then any
walks over all items in tmp
and returns True
as soon as it finds the first truthy element. It's as if you did the following:
In [1]: foobars = ['big', 'small', 'medium', 'nice', 'ugly']
In [2]: big_foobar = 'big'
In [3]: any(['big' == big_foobar, 'small' == big_foobar, 'medium' == big_foobar, 'nice' == big_foobar, 'ugly' == big_foobar])
Out[3]: True
Note: As DSM pointed out, any(x == y for x in xs)
is equivalent to y in xs
but the latter is more readable, quicker to write and runs faster.
Some examples:
In [1]: any(x > 5 for x in range(4))
Out[1]: False
In [2]: all(isinstance(x, int) for x in range(10))
Out[2]: True
In [3]: any(x == 'Erik' for x in ['Erik', 'John', 'Jane', 'Jim'])
Out[3]: True
In [4]: all([True, True, True, False, True])
Out[4]: False

Use ChartNew.js instead of Chart.js
...
So, I have re-worked Chart.js. Most of the changes, are associated to requests in "GitHub" issues of Chart.js.
And here is a sample http://jsbin.com/lakiyu/2/edit
var newopts = {
inGraphDataShow: true,
inGraphDataRadiusPosition: 2,
inGraphDataFontColor: 'white'
}
var pieData = [
{
value: 30,
color: "#F38630",
},
{
value: 30,
color: "#F34353",
},
{
value: 30,
color: "#F34353",
}
]
var pieCtx = document.getElementById('pieChart').getContext('2d');
new Chart(pieCtx).Pie(pieData, newopts);
It even provides a GUI editor http://charts.livegap.com/
So sweet.
Steps to debug:-
In case you face any issue in kubernetes, first step is to check if kubernetes self applications are running fine or not.
Command to check:- kubectl get pods -n kube-system
If you see any pod is crashing, check it's logs
if getting NotReady
state error, verify network pod logs.
if not able to resolve with above, follow below steps:-
kubectl get nodes
# Check which node is not in ready state
kubectl describe node nodename
#nodename which is not in readystate
ssh to that node
execute systemctl status kubelet
# Make sure kubelet is running
systemctl status docker
# Make sure docker service is running
journalctl -u kubelet
# To Check logs in depth
Most probably you will get to know about error here, After fixing it reset kubelet with below commands:-
systemctl daemon-reload
systemctl restart kubelet
In case you still didn't get the root cause, check below things:-
Make sure your node has enough space and memory. Check for /var
directory space especially.
command to check: -df
-kh
, free -m
Verify cpu utilization with top command. and make sure any process is not taking an unexpected memory.
In 12c, here's the new way:
select bla
from bla
where bla
order by finaldate desc
fetch first 1 rows only;
How nice is that!
I would use javascript for this.
var txtFile = new XMLHttpRequest();
txtFile.open("GET", "http://my.remote.url/myremotefile.txt", true);
txtFile.onreadystatechange = function() {
if (txtFile.readyState === 4 && txtFile.status == 200) {
allText = txtFile.responseText;
}
document.getElementById('your div id').innerHTML = allText;
This is just a code sample, would need tweaking for all browsers, etc.
Or you can write your own extension method:
static partial class Extensions
{
public static T WhereMax<T, U>(this IEnumerable<T> items, Func<T, U> selector)
{
if (!items.Any())
{
throw new InvalidOperationException("Empty input sequence");
}
var comparer = Comparer<U>.Default;
T maxItem = items.First();
U maxValue = selector(maxItem);
foreach (T item in items.Skip(1))
{
// Get the value of the item and compare it to the current max.
U value = selector(item);
if (comparer.Compare(value, maxValue) > 0)
{
maxValue = value;
maxItem = item;
}
}
return maxItem;
}
}
vim +21490go script.py
From the command line will open the file and take you to position 21490
in the buffer.
Triggering it from the command line like this allows you to automate a script to parse the exception message and open the file to the problem position.
Excerpt from man vim
:
+{command} -c {command}
{command}
will be executed after the first file has been read.{command}
is interpreted as an Ex command. If the{command}
contains spaces it must be enclosed in double quotes (this depends on the shell that is used).
I am not sure if this has to be explicitly enabled anywhere..but for this to work in the first place you need to include the javadoc jar files with the related jars in your project. Then when you do a Cntrl+Space it shows autocomplete and javadocs.
I use MinGW tool set which provides mingw32-make
build tool, if you have it in your PATH
system variables, in Windows Command Prompt just go into the directory containing the files and type this command:
mingw32-make -f Makefile.win
and it's done.
I know this is old but this answer came up in search results. For the next guy - the proposed and accepted answer works, however the code initially submitted in the question is lower-level than it needs to be. Nobody got time for that.

Have you looked into ControlsFx Popover control.
import org.controlsfx.control.PopOver;
import org.controlsfx.control.PopOver.ArrowLocation;
private PopOver item;
final Scene scene = addItemButton.getScene();
final Point2D windowCoord = new Point2D(scene.getWindow()
.getX(), scene.getWindow().getY());
final Point2D sceneCoord = new Point2D(scene.getX(), scene.
getY());
final Point2D nodeCoord = addItemButton.localToScene(0.0,
0.0);
final double clickX = Math.round(windowCoord.getX()
+ sceneCoord.getY() + nodeCoord.getX());
final double clickY = Math.round(windowCoord.getY()
+ sceneCoord.getY() + nodeCoord.getY());
item.setContentNode(addItemScreen);
item.setArrowLocation(ArrowLocation.BOTTOM_LEFT);
item.setCornerRadius(4);
item.setDetachedTitle("Add New Item");
item.show(addItemButton.getParent(), clickX, clickY);
This is only an example but a PopOver sounds like it could accomplish what you want. Check out the documentation for more info.
Important note: ControlsFX will only work on JavaFX 8.0 b118 or later.
>>> x = 2.51
>>> x*100
250.99999999999997
the floating point numbers are inaccurate. in this case, it is 250.99999999999999, which is really close to 251, but int() truncates the decimal part, in this case 250.
you should take a look at the Decimal module or maybe if you have to do a lot of calculation at the mpmath library http://code.google.com/p/mpmath/ :),
You could spare yourself the transformations, you could use CSS3 Transitions to flip <div>
's and <ol>
's and any HTML tag you want. Here are some demos with source code explain to see and learn: http://www.webdesignerwall.com/trends/47-amazing-css3-animation-demos/
Best thing is to memorize balance equation in natural way.
Amount / Whole = Percentage / 100
usually You have one variable missing, in this case it is Amount
Amount / 10000 = 35.8 / 100
then you have high school math (proportion) to multiple outer from both sides and inner from both sides.
Amount * 100 = 358 000
Amount = 3580
It works the same in all languages and on paper. JavaScript is no exception.
function calc()
{
if (document.getElementById('xxx').checked)
{
document.getElementById('totalCost').value = 10;
} else {
calculate();
}
}

The error is caused because ElementTree did not expect to find non-ASCII strings set the XML when trying to write it out. You should use Unicode strings for non-ASCII instead. Unicode strings can be made either by using the u
prefix on strings, i.e. u'€'
or by decoding a string with mystr.decode('utf-8')
using the appropriate encoding.
The best practice is to decode all text data as it's read, rather than decoding mid-program. The io
module provides an open()
method which decodes text data to Unicode strings as it's read.
ElementTree will be much happier with Unicodes and will properly encode it correctly when using the ET.write()
method.
Also, for best compatibility and readability, ensure that ET encodes to UTF-8 during write()
and adds the relevant header.
Presuming your input file is UTF-8 encoded (0xC2
is common UTF-8 lead byte), putting everything together, and using the with
statement, your code should look like:
with io.open('myText.txt', "r", encoding='utf-8') as f:
data = f.read()
root = ET.Element("add")
doc = ET.SubElement(root, "doc")
field = ET.SubElement(doc, "field")
field.set("name", "text")
field.text = data
tree = ET.ElementTree(root)
tree.write("output.xml", encoding='utf-8', xml_declaration=True)
Output:
<?xml version='1.0' encoding='utf-8'?>
<add><doc><field name="text">data€</field></doc></add>
With help from the accepted answer here and the accepted answer above, I have used:
$ sed 's/^ *//; s/ *$//; /^$/d; /^\s*$/d' file.txt > output.txt
`s/^ *//` => left trim
`s/ *$//` => right trim
`/^$/d` => remove empty line
`/^\s*$/d` => delete lines which may contain white space
This covers all the bases and works perfectly for my needs. Kudos to the original posters @Kent and @kev
This will occur in SQL Server as well if you don't run all of the statements at once. If you are highlighting a set of statements and executing the following:
DECLARE @LoopVar INT
SET @LoopVar = (SELECT COUNT(*) FROM SomeTable)
And then try to highlight another set of statements such as:
PRINT 'LoopVar is: ' + CONVERT(NVARCHAR(255), @LoopVar)
You will receive this error.
You cannot insert data because you have a quota of 0 on the tablespace. To fix this, run
ALTER USER <user> quota unlimited on <tablespace name>;
or
ALTER USER <user> quota 100M on <tablespace name>;
as a DBA user (depending on how much space you need / want to grant).
Expanding on Tony's answer, and also answering Dhaval Ptl's question, to get the true accordion effect and only allow one row to be expanded at a time, an event handler for show.bs.collapse can be added like so:
$('.collapse').on('show.bs.collapse', function () {
$('.collapse.in').collapse('hide');
});
I modified his example to do this here: http://jsfiddle.net/QLfMU/116/
Because your question is phrased regarding your error message and not whatever your function is trying to accomplish, I will address the error.
-
is the 'binary operator' your error is referencing, and either CurrentDay
or MA
(or both) are non-numeric.
A binary operation is a calculation that takes two values (operands) and produces another value (see wikipedia for more). +
is one such operator: "1 + 1" takes two operands (1 and 1) and produces another value (2). Note that the produced value isn't necessarily different from the operands (e.g., 1 + 0 = 1).
R only knows how to apply +
(and other binary operators, such as -
) to numeric arguments:
> 1 + 1
[1] 2
> 1 + 'one'
Error in 1 + "one" : non-numeric argument to binary operator
When you see that error message, it means that you are (or the function you're calling is) trying to perform a binary operation with something that isn't a number.
EDIT:
Your error lies in the use of [
instead of [[
. Because Day
is a list, subsetting with [
will return a list, not a numeric vector. [[
, however, returns an object of the class of the item contained in the list:
> Day <- Transaction(1, 2)["b"]
> class(Day)
[1] "list"
> Day + 1
Error in Day + 1 : non-numeric argument to binary operator
> Day2 <- Transaction(1, 2)[["b"]]
> class(Day2)
[1] "numeric"
> Day2 + 1
[1] 3
Transaction
, as you've defined it, returns a list of two vectors. Above, Day
is a list contain one vector. Day2
, however, is simply a vector.
The code I use for all browser gradients:

background: -webkit-gradient(linear, left top, left bottom, from(#0A284B), to(#135887));
background: -webkit-linear-gradient(#0A284B, #135887);
background: -moz-linear-gradient(top, #0A284B, #135887);

filter: progid:DXImageTransform.Microsoft.gradient(startColorstr='#0A284B', endColorstr='#135887');
zoom: 1;
You will need to specify a height or zoom: 1
to apply hasLayout
to the element for this to work in IE.
Update:
Here is a LESS Mixin (CSS) version for all you LESS users out there:

It seems that the latest function for this in windows 7 is robocopy.
Usage example:
robocopy <source> <destination> /e /xf <file to exclude> <another file>
/e copies subdirectories including empty ones, /xf excludes certain files from being copied.
