C:\ProgramData\Oracle\Java
and delete that directory and all files contained within. You can do this from the command line using rmdir /S C:\ProgramData\Oracle\Java
rmdir /S C:\ProgramData\Oracle
Now install JDK and set the path.
Run the program.You won't find the same problem anymore.
I was debugging an SSL issue today which resulted in the same write:errno=104
error. Eventually I found out that the reason for this behaviour was that the server required SNI (servername
TLS extensions) to work correctly. Supplying the -servername
option to openssl made it connect successfully:
openssl s_client -connect domain.tld:443 -servername domain.tld
Hope this helps.
Just download fart (find and replace text) from here
use it in CMD (for ease of use I add fart folder to my path variable)
here is an example:
fart -r "C:\myfolder\*.*" findSTR replaceSTR
this command will search in C:\myfolder and all sub-folders and replace findSTR with replaceSTR
-r means process sub-folders recursively.
fart is really fast and easy
@echo off
setlocal enableextensions disabledelayedexpansion
set "search=%1"
set "replace=%2"
set "textFile=Input.txt"
for /f "delims=" %%i in ('type "%textFile%" ^& break ^> "%textFile%" ') do (
set "line=%%i"
setlocal enabledelayedexpansion
>>"%textFile%" echo(!line:%search%=%replace%!
endlocal
)
for /f
will read all the data (generated by the type
comamnd) before starting to process it. In the subprocess started to execute the type
, we include a redirection overwritting the file (so it is emptied). Once the do
clause starts to execute (the content of the file is in memory to be processed) the output is appended to the file.
I don't know what the .tex extension on your file means. If we are saying that it is any file with any extension you have several methods of reading it.
I have to assume you are using windows because you have mentioned notepad++.
Use notepad++. Right click on the file and choose "edit with notepad++"
Use notepad Change the filename extension to .txt and double click the file.
Use command prompt. Open the folder that your file is in. Hold down shift and right click. (not on the file, but in the folder that the file is in.) Choose "open command window here" from the command prompt type: "type filename.tex"
If these don't work, I would need more detail as to how they are not working. Errors that you may be getting or what you may expect to be in the file might help.
Besides the session cookie (which is kind of standard), I don't want to use extra cookies.
I found a solution which works for me when building a Single Page Web Application (SPA), with many AJAX requests. Note: I am using server side Java and client side JQuery, but no magic things so I think this principle can be implemented in all popular programming languages.
My solution without extra cookies is simple:
Store the CSRF token which is returned by the server after a succesful login in a global variable (if you want to use web storage instead of a global thats fine of course). Instruct JQuery to supply a X-CSRF-TOKEN header in each AJAX call.
The main "index" page contains this JavaScript snippet:
// Intialize global variable CSRF_TOKEN to empty sting.
// This variable is set after a succesful login
window.CSRF_TOKEN = '';
// the supplied callback to .ajaxSend() is called before an Ajax request is sent
$( document ).ajaxSend( function( event, jqXHR ) {
jqXHR.setRequestHeader('X-CSRF-TOKEN', window.CSRF_TOKEN);
});
On successul login, create a random (and long enough) CSRF token, store this in the server side session and return it to the client. Filter certain (sensitive) incoming requests by comparing the X-CSRF-TOKEN header value to the value stored in the session: these should match.
Sensitive AJAX calls (POST form-data and GET JSON-data), and the server side filter catching them, are under a /dataservice/* path. Login requests must not hit the filter, so these are on another path. Requests for HTML, CSS, JS and image resources are also not on the /dataservice/* path, thus not filtered. These contain nothing secret and can do no harm, so this is fine.
@WebFilter(urlPatterns = {"/dataservice/*"})
...
String sessionCSRFToken = req.getSession().getAttribute("CSRFToken") != null ? (String) req.getSession().getAttribute("CSRFToken") : null;
if (sessionCSRFToken == null || req.getHeader("X-CSRF-TOKEN") == null || !req.getHeader("X-CSRF-TOKEN").equals(sessionCSRFToken)) {
resp.sendError(401);
} else
chain.doFilter(request, response);
}

Why not put the following in your .cshrc
(or .bashrc
, or whatever your default shell is):
alias mydoc 'cd "/cygdrive/c/Users/my dir/Documents"'
First time you do this, you have to do
source .cshrc
to update the shell with this new alias, then you can type
mydoc
anytime you want to cd
to your directory.
Laziness is the mother of invention...

I was having similar issue and I think if we simply ignore the ssl
verification will work like charm as it worked for me. So connecting to server with https
scheme but directing them not to verify the certificate.
Using requests
. Just mention verify=False
instead of None
requests.post(url, data=payload, headers=headers, verify=False)
Hoping this will work for those who needs :).
just use printf
instead of
repo forall -c '....$variable'
use printf to replace the variable token with the expanded variable.
For example:
template='.... %s'
repo forall -c $(printf "${template}" "${variable}")
Retrieve nuget.exe
from https://www.nuget.org/downloads
. Copy it to a local folder and add that folder to the PATH
environment variable.
This is will make nuget available globally, from any project.
If You want your upper axis to be a function of the lower axis tick-values you can do as below. Please note: sometimes get_xticks()
will have a ticks outside of the visible range, which you have to allow for when converting.
import matplotlib.pyplot as plt
fig, ax1 = plt.subplots()
ax1 = fig.add_subplot(111)
ax1.plot(range(5), range(5))
ax1.grid(True)
ax2 = ax1.twiny()
ax2.set_xticks( ax1.get_xticks() )
ax2.set_xbound(ax1.get_xbound())
ax2.set_xticklabels([x * 2 for x in ax1.get_xticks()])
title = ax1.set_title("Upper x-axis ticks are lower x-axis ticks doubled!")
title.set_y(1.1)
fig.subplots_adjust(top=0.85)
fig.savefig("1.png")

Try downloading "Java Cryptography Extension (JCE) Unlimited Strength Jurisdiction Policy Files" from the Java download site and replacing the files in your JRE.
This worked for me and I didn't even need to use BouncyCastle - the standard Sun JCE was able to connect to the server.
PS. I got the same error (ArrayIndexOutOfBoundsException: 64) when I tried using BouncyCastle before changing the policy files, so it seems our situation is very similar.
A real problem often exists because any variables set inside will not be exported when that batch file finishes. So its not possible to export, which caused us issues. As a result, I just set the registry to ALWAYS used delayed expansion (I don't know why it's not the default, could be speed or legacy compatibility issue.)
Aside from the ones you mention, I only use frequently when diffing the following:
:diffupdate
:diffu
-> recalculate the diff, useful when after making several changes vim's isn't showing minimal changes anymore. Note that it only works if the files have been modified inside vimdiff. Otherwise, use:
:e
to reload the files if they have been modified outside of vimdiff. :set noscrollbind
-> temporarily disable simultaneous scrolling on both buffers, reenable by :set scrollbind
and scrolling.Most of what you asked for is folding: vim user manual's chapter on folding. Outside of diffs I sometime use:
zo
-> open fold.zc
-> close fold.But you'll probably be better served by:
zr
-> reducing folding level.zm
-> one more folding level, please.or even:
zR
-> Reduce completely the folding, I said!.zM
-> fold Most!.The other thing you asked for, use n lines of folding, can be found at the vim reference manual section on options, via the section on diff:
set diffopt=<TAB>
, then update or add context:n
.You should also take a look at the user manual section on diff.
I had this same problem, because my line of code was:
txtTotalInvoice.setText(var1.divide(var2).doubleValue() + "");
I change to this, reading previous Answer, because I was not writing decimal precision:
txtTotalInvoice.setText(var1.divide(var2,4, RoundingMode.HALF_UP).doubleValue() + "");
4 is Decimal Precison
AND RoundingMode are Enum constants, you could choose any of this
UP, DOWN, CEILING, FLOOR, HALF_DOWN, HALF_EVEN, HALF_UP
In this Case HALF_UP, will have this result:
2.4 = 2
2.5 = 3
2.7 = 3
You can check the RoundingMode

Brace expansion doesn't work, but *
, ?
and []
do. If you set shopt -s extglob
then you can also use extended pattern matching:
?()
- zero or one occurrences of pattern*()
- zero or more occurrences of pattern+()
- one or more occurrences of pattern@()
- one occurrence of pattern!()
- anything except the patternHere's an example:
shopt -s extglob
for arg in apple be cd meet o mississippi
do
# call functions based on arguments
case "$arg" in
a* ) foo;; # matches anything starting with "a"
b? ) bar;; # matches any two-character string starting with "b"
c[de] ) baz;; # matches "cd" or "ce"
me?(e)t ) qux;; # matches "met" or "meet"
@(a|e|i|o|u) ) fuzz;; # matches one vowel
m+(iss)?(ippi) ) fizz;; # matches "miss" or "mississippi" or others
* ) bazinga;; # catchall, matches anything not matched above

Just add <div>
tag inside <td>
or <th>
define width inside <div>
.
This will help you. Nothing else works.
eg.
<td><div style="width: 50px" >...............</div></td>
Use a colon:
: ${A:=hello}
The colon is a null command that does nothing and ignores its arguments. It is built into bash so a new process is not created.
In general, one doesn't expand out log(a + b)
; you just deal with it as is. That said, there are occasionally circumstances where it makes sense to use the following identity:
log(a + b) = log(a * (1 + b/a)) = log a + log(1 + b/a)
(In fact, this identity is often used when implementing log
in math libraries).
I had the same problem. Don't remember where I found it on the web, but here is what I did:
Click "Start button"
in the search box, enter "Turn windows features on or off"
in the features window, Click: "Internet Information Services"
Click: "World Wide Web Services"
Click: "Application Development Features"
Check (enable) the features. I checked all but CGI.
IIS - this configuration section cannot be used at this path (configuration locking?)
I have the same problem with mysqli. My solution is https://www.php.net/manual/en/mysqli.configuration.php

check for this by calling the library jquery after the noconflict.js or that this calling more than once jquery library after the noconflict.js
Update: Per konrad.kruczynski's answer, the following is true for versions of .NET up to and including 4.0.
You can use the MethodImplAttribute class to prevent a method from being inlined...
[MethodImpl(MethodImplOptions.NoInlining)]
void SomeMethod()
{
// ...
}
...but there is no way to do the opposite and force it to be inlined.
Reloading existing classes with existing data is likely to break things.
You can load new code into new class loaders relatively easily:
ClassLoader loader = URLClassLoader.newInstance(
new URL[] { yourURL },
getClass().getClassLoader()
);
Class<?> clazz = Class.forName("mypackage.MyClass", true, loader);
Class<? extends Runnable> runClass = clazz.asSubclass(Runnable.class);
// Avoid Class.newInstance, for it is evil.
Constructor<? extends Runnable> ctor = runClass.getConstructor();
Runnable doRun = ctor.newInstance();
doRun.run();
Class loaders no longer used can be garbage collected (unless there is a memory leak, as is often the case with using ThreadLocal, JDBC drivers, java.beans
, etc).
If you want to keep the object data, then I suggest a persistence mechanism such as Serialisation, or whatever you are used to.
Of course debugging systems can do fancier things, but are more hacky and less reliable.
It is possible to add new classes into a class loader. For instance, using URLClassLoader.addURL
. However, if a class fails to load (because, say, you haven't added it), then it will never load in that class loader instance.
Here is why the original expression didn't work.
From man bash:
Brace expansion is performed before any other expansions, and any characters special to other expansions are preserved in the result. It is strictly textual. Bash does not apply any syntactic interpretation to the context of the expansion or the text between the braces.
So, brace expansion is something done early as a purely textual macro operation, before parameter expansion.
Shells are highly optimized hybrids between macro processors and more formal programming languages. In order to optimize the typical use cases, the language is made rather more complex and some limitations are accepted.
Recommendation
I would suggest sticking with Posix1 features. This means using for i in <list>; do
, if the list is already known, otherwise, use while
or seq
, as in:
#!/bin/sh
limit=4
i=1; while [ $i -le $limit ]; do
echo $i
i=$(($i + 1))
done
# Or -----------------------
for i in $(seq 1 $limit); do
echo $i
done
Create a file called "SetFile.bat" that contains the following line with no carriage return at the end of it...
set FileContents=
Then in your batch file do something like this...
@echo off
copy SetFile.bat + %1 $tmp$.bat > nul
call $tmp$.bat
del $tmp$.bat
%1 is the name of your input file and %FileContents% will contain the contents of the input file after the call. This will only work on a one line file though (i.e. a file containing no carriage returns). You could strip out/replace carriage returns from the file before calling the %tmp%.bat if needed.
I went through the solutions on the internet. Mostly solutions didn't work in the project I'm working on. Following solutions work fine for me.
Using onScrollChangeListener (works on API 23):

if(scrollY==0){
//top detected
}
if(bottom==0){
//bottom detected
}
}
});
}
using scrollChangeListener on TreeObserver
scrollView.getViewTreeObserver().addOnScrollChangedListener(new ViewTreeObserver.OnScrollChangedListener() {
@Override
public void onScrollChanged() {
int bottom = (scrollView.getChildAt(scrollView.getChildCount() - 1)).getHeight()-scrollView.getHeight()-scrollView.getScrollY();
if(scrollView.getScrollY()==0){
//top detected
}
if(bottom==0) {
//bottom detected
}
}
});
Hope this solution helps :)
The direct way of doing this is to create triggers on tables. Set some conditions or mapping methods. When update or delete occurs, it will insert into 'change' table automatically.
But the biggest part is what if we got lots columns and lots of table. We have to type every column's name of every table. Obviously, It's waste of time.
To handle this more gorgeously, we can create some procedures or functions to retrieve name of columns.
We can also use 3rd-part tool simply to do this. Here, I write a java program Mysql Tracker
Here's a list of things that are worth checking:
Is Suhosin installed?

ini_set('memory_limit', '512'); // DIDN'T WORK
ini_set('memory_limit', '512MB'); // DIDN'T WORK
ini_set('memory_limit', '512M'); // OK - 512MB
ini_set('memory_limit', 512000000); // OK - 512MB

I think you are using the 64-bit version of the tool to install a 32-bit application. I've also faced this issue today and used this Framework path to cater .
C:\Windows\Microsoft.NET\Framework\v4.0.30319
and it should install your 32-bit application just fine.
Since strings are objects and since all objects in Java are always stored only in the heap space, all strings are stored in the heap space. However, Java keeps strings created without using the new keyword in a special area of the heap space, which is called "string pool". Java keeps the strings created using the new keyword in the regular heap space.
The purpose of the string pool is to maintain a set of unique strings. Any time you create a new string without using the new keyword, Java checks whether the same string already exists in the string pool. If it does, Java returns a reference to the same String object and if it does not, Java creates a new String object in the string pool and returns its reference. So, for example, if you use the string "hello" twice in your code as shown below, you will get a reference to the same string. We can actually test this theory out by comparing two different reference variables using the == operator as shown in the following code:
String str1 = "hello";
String str2 = "hello";
System.out.println(str1 == str2); //prints true
String str3 = new String("hello");
String str4 = new String("hello");
System.out.println(str1 == str3); //prints false
System.out.println(str3 == str4); //prints false
== operator is simply checks whether two references point to the same object or not and returns true if they do. In the above code, str2 gets the reference to the same String object which was created earlier. However, str3 and str4 get references to two entirely different String objects. That is why str1 == str2 returns true but str1 == str3 and str3 == str4 return false . In fact, when you do new String("hello"); two String objects are created instead of just one if this is the first time the string "hello" is used in the anywhere in program - one in the string pool because of the use of a quoted string, and one in the regular heap space because of the use of new keyword.
String pooling is Java's way of saving program memory by avoiding the creation of multiple String objects containing the same value. It is possible to get a string from the string pool for a string created using the new keyword by using String's intern method. It is called "interning" of string objects. For example,
String str1 = "hello";
String str2 = new String("hello");
String str3 = str2.intern(); //get an interned string obj
System.out.println(str1 == str2); //prints false
System.out.println(str1 == str3); //prints true
After trying almost every post on this thread and reading through apple developer forums I found only one solution worked for me.
I am building a universal framework that is consumed in a swift app. I was unable to build to the Simulator without architecture errors.
In my Framework project I have a Universal Framework task in my build phases, if this is the case for you
xcodebuild
task inside the build phase:
EXCLUDED_ARCHS="arm64"
Next you have to change the following project Build Settings
:
VALID_ARCHS
user defined settingONLY_ACTIVE_ARCH
to YES
****** If you are developing a framework and have a demo app as well, this setting has to be turned on in both projects.
I had a horizontal scrolling collection view (I use collection view in Tableview) and I too faced problems withcell reuse, whenever I select one item and scroll towards right, some other cells in the next visible set gets select automatically. Trying to solve this using any custom cell properties like "selected", highlighted etc didnt help me so I came up with the below solution and this worked for me.
Step1:
Create a variable in the collectionView to store the selected index, here I have used a class level variable called selectedIndex
- (UICollectionViewCell *)collectionView:(UICollectionView *)collectionView cellForItemAtIndexPath:(NSIndexPath *)indexPath
{
MyCVCell *cell = (MyCVCell*)[collectionView dequeueReusableCellWithReuseIdentifier:@"MyCVCell" forIndexPath:indexPath];
// When scrolling happens, set the selection status only if the index matches the selected Index
if (selectedIndex == indexPath.row) {
cell.layer.borderWidth = 1.0;
cell.layer.borderColor = [[UIColor redColor] CGColor];
}
else
{
// Turn off the selection
cell.layer.borderWidth = 0.0;
}
return cell;
}
- (void)collectionView:(UICollectionView *)collectionView didSelectItemAtIndexPath:(NSIndexPath *)indexPath

If you only need a current value and above options don't work, you can use it this way.
$('#input').on('change', () => {
const current = document.getElementById('input').value;
}
You need to use linecolor instead of lc, like:
set style line 1 lt 1 lw 3 pt 3 linecolor rgb "red"
"help set style line" gives you more info.
In addition to Tim's answer, which is very appropriate to your specific example, it's worth mentioning collections.defaultdict
, which lets you do stuff like this:
>>> d = defaultdict(int)
>>> d[0] += 1
>>> d
{0: 1}
>>> d[4] += 1
>>> d
{0: 1, 4: 1}
For mapping [1, 2, 3, 4]
as in your example, it's a fish out of water. But depending on the reason you asked the question, this may end up being a more appropriate technique.

Hope this helps :)
The unset
array_search
has some pretty terrible side effects because it can accidentally strip the first element off your array regardless of the value:
// bad side effects
$a = [0,1,2,3,4,5];
unset($a[array_search(3, $a)]);
unset($a[array_search(6, $a)]);
$this->log_json($a);
// result: [1,2,4,5]
// what? where is 0?
// it was removed because false is interpreted as 0
// goodness
$b = [0,1,2,3,4,5];
$b = array_diff($b, [3,6]);
$this->log_json($b);
// result: [0,1,2,4,5]
If you know that the value is guaranteed to be in the array, go for it, but I think the array_diff
is far safer. (I'm using php7)
TL;DR: All well written web sites (/apps) must emit the header X-XSS-Protection: 0
and just forget about this feature. If you want to have extra security that better user agents can provide, use a strict Content-Security-Policy
header.
Long answer:
HTTP header X-XSS-Protection
is one of those things that Microsoft introduced in Internet Explorer 8.0 (MSIE 8) that was supposed to improve security of incorrectly written web sites.
The idea is to apply some kind of heuristics to try to detect reflection XSS attack and automatically neuter the attack.
The problematic part of this is "heuristics" and "neutering". The heuristics causes false positives and neutering cannot be safely done because it causes side-effects that can be used to implement XSS attacks and DoS attacks on perfectly safe web sites.
The bad part is that if a web site does not emit the header X-XSS-Protection
then the browser will behave as if the header X-XSS-Protection: 1
had been emitted. The worst part is that this value is the least-safe value of all possible values for this header!
For a given secure web site (that is, the site does not have reflected XSS vulnerabilities) this "XSS protection" feature allows following attacks:
X-XSS-Protection: 1
allows attacker to selectively block parts of JavaScript and keep rest of the scripts running. This is possible because the heuristics of this feature are simply "if value of any GET parameter is found in the scripting part of the page source, the script will be automatically modified in user agent dependant way". In practice, the attacker can e.g. add parameter disablexss=<script src="framebuster.js"
and the browser will automatically remove the string <script src="framebuster.js"
from the actual page source. Note that the rest of the page continues run and the attacker just removed this part of page security. In practice, any JS in the page source can be modified. For some cases, a page without XSS vulnerability having reflected content can be used to run selected JavaScript on page due the neutering incorrectly turning plain text data into executable JavaScript code. (That is, turn textual data within a normal DOM text node into content of <script>
tag and execute it!)
X-XSS-Protection: 1; mode=block
allows attacker to leak data from the page source by using the behavior of the page as side-channel. For example, if the page contains JavaScript code along the lines of var csrf_secret="521231347843"
, the attacker simply adds an extra parameter e.g. leak=var%20csrf_secret="3
and if the page is NOT blocked, the 3
was incorrect first digit. The attacker tries again, this time leak=var%20csrf_secret="5
and the page loading will be aborted. This allows the attacker to know that the first digit of the secret is 5
. The attacker then continues to guess the next digit. This allows easily brute-forcing of CSRF secrets or any other secret value in the <script>
source.
In the end, if your site is full of XSS reflection attacks, using the default value of 1
will reduce the attack surface a little bit. However, if your site is secure and you don't emit X-XSS-Protection: 0
, your site will be vulnerable with any browser that supports this feature. If you want defense in depth support from browsers against yet-unknown XSS vulnerabilities on your site, use a strict Content-Security-Policy
header and keep sending 0
for this mis-feature. That doesn't open your site to any known vulnerabilities.
Currently this feature is enabled by default in MSIE, Safari and Google Chrome. This used to be enabled in Edge but Microsoft already removed this mis-feature from Edge. Mozilla Firefox never implemented this.

Definitely this gives good solution,
ResultSet rs = stmt.execute("SQL QUERY");
// With the above statement you will not have a null ResultSet 'rs'.
// In case, if any exception occurs then next line of code won't execute.
// So, no problem if I won't check rs as null.
if (rs.next()) {
do {
// Logic to retrieve the data from the resultset.
// eg: rs.getString("abc");
} while(rs.next());
} else {
// No data
}
Before doing a force deletion i would first do some checks. 1- node state: get the node name where your node is running, you can see this with the following command:
"kubectl -n YOUR_NAMESPACE describe pod YOUR_PODNAME"
Under the "Node" label you will see the node name. With that you can do:
kubectl describe node NODE_NAME
Check the "conditions" field if you see anything strange. If this is fine then you can move to the step, redo:
"kubectl -n YOUR_NAMESPACE describe pod YOUR_PODNAME"
Check the reason why it is hanging, you can find this under the "Events" section. I say this because you might need to take preliminary actions before force deleting the pod, force deleting the pod only deletes the pod itself not the underlying resource (a stuck docker container for example).
sudo mv /filename /etc/init.d/
sudo chmod +x /etc/init.d/filename
sudo update-rc.d filename defaults
Script should now start on boot. Note that this method also works with both hard links and symbolic links (ln
).
At this point in the boot process PATH isn't set yet, so it is critical that absolute paths are used throughout. BUT, as pointed out in the comments by Steve HHH, explicitly declaring the full file path (/etc/init.d/filename
) for the update-rc.d command is not valid in most versions of Linux. Per the manpage for update-rc.d, the second parameter is a script located in /etc/init.d/*
. Updated above code to reflect this.
Also as pointed out in the comments (by Charles Brandt), /filename
must be an init style script. A good template was also provided - https://github.com/fhd/init-script-template.
Another link to another article just to avoid possible link rot (although it would be saddening if GitHub died) - http://www.linux.com/learn/tutorials/442412-managing-linux-daemons-with-init-scripts
As pointed out in the comments (by Russell Yan), This works only on default mode of update-rc.d.
According to manual of update-rc.d, it can run on two modes, "the machines using the legacy mode will have a file /etc/init.d/.legacy-bootordering
", in which case you have to pass sequence and runlevel configuration through command line arguments.
The equivalent argument set for the above example is
sudo update-rc.d filename start 20 2 3 4 5 . stop 20 0 1 6 .
I had this problem with a ComboBox displaying a list of colors ( List<Brush> ).
Selecting a color was possible but it wasnt displayed when the selection closed (although the property was changed!)
The fix was overwriting the Equals(object obj) method for the type selected in the ComboBox (Brush), which wasnt simple because Brush is sealed. So i wrote a class EqualityBrush containing a Brush and implementing Equals:
public class EqualityBrush
{
public SolidColorBrush Brush { get; set; }
public override bool Equals(object o)
{
if (o is EqualityBrush)
{
SolidColorBrush b = ((EqualityBrush)o).Brush;
return b.Color.R == this.Brush.Color.R && b.Color.G == this.Brush.Color.G && b.Color.B == this.Brush.Color.B;
}
else
return false;
}
}
Using a List of my new EqualityBrush class instead of normal Brush class fixed the problem!
My Combobox XAML looks like this:
<ComboBox ItemsSource="{Binding BuerkertBrushes}" SelectedItem="{Binding Brush, Mode=TwoWay}" Width="40">
<ComboBox.Resources>
<DataTemplate DataType="{x:Type tree:EqualityBrush}">
<Rectangle Width="20" Height="12" Fill="{Binding Brush}"/>
</DataTemplate>
</ComboBox.Resources>
</ComboBox>
Remember that my "Brush"-Property in the ViewModel now has to be of Type EqualityBrush!
Yes, %d
means decimal, but it means decimal number system, not decimal point.
Further, as a complement to the former post, you can also control the number of decimal points to show. Try this,
System.out.printf("%.2f %.1f",d,f); // prints 1.20 1.2
For more please refer to the API docs.
As I have found and wrote in another topic - this applies to angular < 7 (not sure how it is in 7+)
Just for the future
we need to observe that [(ngModel)]="hero.name"
is just a short-cut that can be de-sugared to: [ngModel]="hero.name" (ngModelChange)="hero.name = $event"
.
So if we de-sugar code we would end up with:
<select (ngModelChange)="onModelChange()" [ngModel]="hero.name" (ngModelChange)="hero.name = $event">
or
<[ngModel]="hero.name" (ngModelChange)="hero.name = $event" select (ngModelChange)="onModelChange()">
If you inspect the above code you will notice that we end up with 2 ngModelChange
events and those need to be executed in some order.
Summing up: If you place ngModelChange
before ngModel
, you get the $event
as the new value, but your model object still holds previous value.
If you place it after ngModel
, the model will already have the new value.
Another workaround is just to set the li
item to flex
or inline-flex
. Depending on the circumstances that may suit you better. In case you have a real icon / image placed in the HTML the default flex position is on the central horizontal line.
A simple solution would be to configure static http headers needed for all calls in the bean configuration of the RestTemplate:
@Configuration
public class RestTemplateConfig {
@Bean
public RestTemplate getRestTemplate(@Value("${did-service.bearer-token}") String bearerToken) {
RestTemplate restTemplate = new RestTemplate();
restTemplate.getInterceptors().add((request, body, clientHttpRequestExecution) -> {
HttpHeaders headers = request.getHeaders();
if (!headers.containsKey("Authorization")) {
String token = bearerToken.toLowerCase().startsWith("bearer") ? bearerToken : "Bearer " + bearerToken;
request.getHeaders().add("Authorization", token);
}
return clientHttpRequestExecution.execute(request, body);
});
return restTemplate;
}
}

This answer will show you that how to work in asp.net with razor, and to control multiple submit button event. Lets for example we have two button, one button will redirect us to "PageA.cshtml" and other will redirect us to "PageB.cshtml".
@{
if (IsPost)
{
if(Request["btn"].Equals("button_A"))
{
Response.Redirect("PageA.cshtml");
}
if(Request["btn"].Equals("button_B"))
{
Response.Redirect("PageB.cshtml");
}
}
}
<form method="post">
<input type="submit" value="button_A" name="btn"/>;
<input type="submit" value="button_B" name="btn"/>;
</form>
Here's a macro that allows you to shuffle selected cells in a column:
Option Explicit
Sub ShuffleSelectedCells()
'Do nothing if selecting only one cell
If Selection.Cells.Count = 1 Then Exit Sub
'Save selected cells to array
Dim CellData() As Variant
CellData = Selection.Value
'Shuffle the array
ShuffleArrayInPlace CellData
'Output array to spreadsheet
Selection.Value = CellData
End Sub
Sub ShuffleArrayInPlace(InArray() As Variant)
''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''
' ShuffleArrayInPlace
' This shuffles InArray to random order, randomized in place.
' Source: http://www.cpearson.com/excel/ShuffleArray.aspx
' Modified by Tom Doan to work with Selection.Value two-dimensional arrays.
''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''
Dim J As Long, _
N As Long, _
Temp As Variant
'Randomize
For N = LBound(InArray) To UBound(InArray)
J = CLng(((UBound(InArray) - N) * Rnd) + N)
If J <> N Then
Temp = InArray(N, 1)
InArray(N, 1) = InArray(J, 1)
InArray(J, 1) = Temp
End If
Next N
End Sub
You can read the comments to see what the macro is doing. Here's how to install the macro:
Now you can assign the "ShuffleSelectedCells" macro to an icon or hotkey to quickly randomize your selected rows (keep in mind that you can only select one column of rows).
They're pretty much the same - the only difference is that a variable you pass as an out
parameter doesn't need to be initialized but passing it as a ref
parameter it has to be set to something.
int x;
Foo(out x); // OK
int y;
Foo(ref y); // Error: y should be initialized before calling the method
Ref
parameters are for data that might be modified, out
parameters are for data that's an additional output for the function (eg int.TryParse
) that are already using the return value for something.
Use getopt()
, or perhaps getopt_long()
.
int iflag = 0;
enum { WORD_MODE, LINE_MODE } op_mode = WORD_MODE; // Default set
int opt;
while ((opt = getopt(argc, argv, "ilw") != -1)
{
switch (opt)
{
case 'i':
iflag = 1;
break;
case 'l':
op_mode = LINE_MODE;
break;
case 'w':
op_mode = WORD_MODE;
break;
default:
fprintf(stderr, "Usage: %s [-ilw] [file ...]\n", argv[0]);
exit(EXIT_FAILURE);
}
}
/* Process file names or stdin */
if (optind >= argc)
process(stdin, "(standard input)", op_mode);
else
{
int i;
for (i = optind; i < argc; i++)
{
FILE *fp = fopen(argv[i], "r");
if (fp == 0)
fprintf(stderr, "%s: failed to open %s (%d %s)\n",
argv[0], argv[i], errno, strerror(errno));
else
{
process(fp, argv[i], op_mode);
fclose(fp);
}
}
}
Note that you need to determine which headers to include (I make it 4 that are required), and the way I wrote the op_mode
type means you have a problem in the function process()
- you can't access the enumeration down there. It's best to move the enumeration outside the function; you might even make op_mode
a file-scope variable without external linkage (a fancy way of saying static
) to avoid passing it to the function. This code does not handle -
as a synonym for standard input, another exercise for the reader. Note that getopt()
automatically takes care of --
to mark the end of options for you.
I've not run any version of the typing above past a compiler; there could be mistakes in it.
For extra credit, write a (library) function:
int filter(int argc, char **argv, int idx, int (*function)(FILE *fp, const char *fn));
which encapsulates the logic for processing file name options after the getopt()
loop. It should handle -
as standard input. Note that using this would indicate that op_mode
should be a static file scope variable. The filter()
function takes argc
, argv
, optind
and a pointer to the processing function. It should return 0 (EXIT_SUCCESS) if it was able to open all the files and all invocations of the function reported 0, otherwise 1 (or EXIT_FAILURE). Having such a function simplifies writing Unix-style 'filter' programs that read files specified on the command line or standard input.
Try to change Tomcat version, in my case tomcat "8.0.41" and "8.5.8" didn't work. But "8.5.37" worked fine.
armhf
stands for "arm hard float", and is the name given to a debian port for arm processors (armv7+) that have hardware floating point support.
On the beaglebone black, for example:
:~$ dpkg --print-architecture
armhf
Although other commands (such as uname -a
or arch
) will just show armv7l
:~$ cat /proc/cpuinfo
processor : 0
model name : ARMv7 Processor rev 2 (v7l)
BogoMIPS : 995.32
Features : half thumb fastmult vfp edsp thumbee neon vfpv3 tls
...
The vfpv3
listed under Features
is what refers to the floating point support.
Incidentally, armhf
, if your processor supports it, basically supersedes Raspbian, which if I understand correctly was mainly a rebuild of armhf
with work arounds to deal with the lack of floating point support on the original raspberry pi's. Nowdays, of course, there's a whole ecosystem build up around Raspbian, so they're probably not going to abandon it. However, this is partly why the beaglebone runs straight debian, and that's ok even if you're used to Raspbian, unless you want some of the special included non-free software such as Mathematica.

Hopefully this is self explanatory enough. Use the comments in the code to help understand what is happening. Pass a single cell to this function. The value of that cell will be the base file name. If the cell contains "AwesomeData" then we will try and create a file in the current users desktop called AwesomeData.pdf. If that already exists then try AwesomeData2.pdf and so on. In your code you could just replace the lines filename = Application.....
with filename = GetFileName(Range("A1"))
Function GetFileName(rngNamedCell As Range) As String
Dim strSaveDirectory As String: strSaveDirectory = ""
Dim strFileName As String: strFileName = ""
Dim strTestPath As String: strTestPath = ""
Dim strFileBaseName As String: strFileBaseName = ""
Dim strFilePath As String: strFilePath = ""
Dim intFileCounterIndex As Integer: intFileCounterIndex = 1
' Get the users desktop directory.
strSaveDirectory = Environ("USERPROFILE") & "\Desktop\"
Debug.Print "Saving to: " & strSaveDirectory
' Base file name
strFileBaseName = Trim(rngNamedCell.Value)
Debug.Print "File Name will contain: " & strFileBaseName
' Loop until we find a free file number
Do
If intFileCounterIndex > 1 Then
' Build test path base on current counter exists.
strTestPath = strSaveDirectory & strFileBaseName & Trim(Str(intFileCounterIndex)) & ".pdf"
Else
' Build test path base just on base name to see if it exists.
strTestPath = strSaveDirectory & strFileBaseName & ".pdf"
End If
If (Dir(strTestPath) = "") Then
' This file path does not currently exist. Use that.
strFileName = strTestPath
Else
' Increase the counter as we have not found a free file yet.
intFileCounterIndex = intFileCounterIndex + 1
End If
Loop Until strFileName <> ""
' Found useable filename
Debug.Print "Free file name: " & strFileName
GetFileName = strFileName
End Function
The debug lines will help you figure out what is happening if you need to step through the code. Remove them as you see fit. I went a little crazy with the variables but it was to make this as clear as possible.
In Action
My cell O1 contained the string "FileName" without the quotes. Used this sub to call my function and it saved a file.

Where is your code located in reference to everything else? Perhaps you need to make a module if you have not already and move your existing code into there.
In my case, I had a sequence with the same name.
Try this:
<tr ng-repeat="player in players | filter:{id: player_id, name:player_name} | filter:ageFilter">
$scope.ageFilter = function (player) {
return (player.age > $scope.min_age && player.age < $scope.max_age);
}
I figured it out. Basically it's an async issue. You can't just submit and expect to render the subsequent page immediately. You have to wait until the onLoad event for the next page is triggered. My code is below:
var page = new WebPage(), testindex = 0, loadInProgress = false;
page.onConsoleMessage = function(msg) {
console.log(msg);
};
page.onLoadStarted = function() {
loadInProgress = true;
console.log("load started");
};
page.onLoadFinished = function() {
loadInProgress = false;
console.log("load finished");
};
var steps = [
function() {
//Load Login Page
page.open("https://website.com/theformpage/");
},
function() {
//Enter Credentials
page.evaluate(function() {
var arr = document.getElementsByClassName("login-form");
var i;
for (i=0; i < arr.length; i++) {
if (arr[i].getAttribute('method') == "POST") {
arr[i].elements["email"].value="mylogin";
arr[i].elements["password"].value="mypassword";
return;
}
}
});
},
function() {
//Login
page.evaluate(function() {
var arr = document.getElementsByClassName("login-form");
var i;
for (i=0; i < arr.length; i++) {
if (arr[i].getAttribute('method') == "POST") {
arr[i].submit();
return;
}
}
});
},
function() {
// Output content of page to stdout after form has been submitted
page.evaluate(function() {
console.log(document.querySelectorAll('html')[0].outerHTML);
});
}
];
interval = setInterval(function() {
if (!loadInProgress && typeof steps[testindex] == "function") {
console.log("step " + (testindex + 1));
steps[testindex]();
testindex++;
}
if (typeof steps[testindex] != "function") {
console.log("test complete!");
phantom.exit();
}
}, 50);

As I knowit, encapsulation is hiding data of classes in themselves, and only making it accessible via setters / getters, if they must be accessed from the outer world.
Abstraction is the class design for itself.
Means, how You create Your class tree, which methods are general ones, which are inherited, which can be overridden,which attributes are only on private level, or on protected, how Do You build up Your class inheritance tree, Do You use final classes, abtract classes, interface-implementation.
Abstraction is more placed the oo-design phase, while encapsulation also enrolls into developmnent-phase.
Be careful with the "Range(...)" without first qualifying a Worksheet because it will use the currently Active worksheet to make the copy from. It's best to fully qualify both sheets. Please give this a shot (please change "Sheet1" with the copy worksheet):

You can use this function to query for any element on the page, regardless of if it is nested inside of an iframe (or many iframes):
function querySelectorAllInIframes(selector) {
let elements = [];
const recurse = (contentWindow = window) => {
const iframes = contentWindow.document.body.querySelectorAll('iframe');
iframes.forEach(iframe => recurse(iframe.contentWindow));
elements = elements.concat(contentWindow.document.body.querySelectorAll(selector));
}
recurse();
return elements;
};
querySelectorAllInIframes('#elementToBeFound');
Note: Keep in mind that each of the iframes on the page will need to be of the same-origin, or this function will throw an error.

Use mktemp -d
. It creates a temporary directory with a random name and makes sure that file doesn't already exist. You need to remember to delete the directory after using it though.
PROBLEM RESOLVED
In my case the problem was that I do the ajax call (with $.ajax, $.get or $.getJSON methods from jQuery) with full path in the url param:
But the correct way is to pass the value of url as:
url: "site/cgi-bin/serverApp.php"
Some browser don't conflict and make no distiction between one text or another, but in Firefox 3.6 for Mac OS take this full path as "cross site scripting"... another thing, in the same browser there is a distinction between:
http://mydomain.com/site/index.html
And put
http://www.mydomain.com/site/index.html
In fact it is the correct point view, but most implementations make no distinction, so the solution was to remove all the text that specify the full path to the script in the methods that do the ajax request AND.... remove any BASE tag in the index.html file
base href="http://mydomain.com/" <--- bad idea, remove it!
If you don't remove it, this version of browser for this system may take your ajax request like if it is a cross site request!
I have the same problem but only on the Mac OS machine. The problem is that Firefox treat the ajax response as an "cross site" call, in any other machine/browser it works fine. I didn't found any help about this (I think that is a firefox implementation issue), but I'm going to prove the next code at the server side:
header('Content-type: application/json');
to ensure that browser get the data as "json data" ...
This works for me.

To add to josh's answer,
you may make the alias(es) persistent with the following steps,
DOSKEY
commands.HKEY_CURRENT_USER\Software\Microsoft\Command Processor
Add String Value entry with the name AutoRun
and the full path of your .bat/.cmd file.
For example, %USERPROFILE%\alias.cmd
, replacing the initial segment of the path with %USERPROFILE%
is useful for syncing among multiple machines.
This way, every time cmd is run, the aliases are loaded.
For Windows 10, add the entry to HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Command Processor
instead.
For completeness, here is a template to illustrate the kind of aliases one may find useful.
@echo off
:: Temporary system path at cmd startup
set PATH=%PATH%;"C:\Program Files\Sublime Text 2\"
:: Add to path by command
DOSKEY add_python26=set PATH=%PATH%;"C:\Python26\"
DOSKEY add_python33=set PATH=%PATH%;"C:\Python33\"
:: Commands
DOSKEY ls=dir /B
DOSKEY sublime=sublime_text $*
::sublime_text.exe is name of the executable. By adding a temporary entry to system path, we don't have to write the whole directory anymore.
DOSKEY gsp="C:\Program Files (x86)\Sketchpad5\GSP505en.exe"
DOSKEY alias=notepad %USERPROFILE%\Dropbox\alias.cmd
:: Common directories
DOSKEY dropbox=cd "%USERPROFILE%\Dropbox\$*"
DOSKEY research=cd %USERPROFILE%\Dropbox\Research\
$*
syntax works after a directory string as well as an executable which takes in arguments. So in the above example, the user-defined command dropbox research
points to the same directory as research
.alias.cmd
file. See alias
above. If you are in a cmd session, enter cmd
to restart cmd and reload the alias.cmd
file.When I searched the internet for an answer to the question, somehow the discussions were either focused on persistence only or on some usage of DOSKEY only. I hope someone will benefit from these two aspects being together here!
Here's a .reg
file to help you install the alias.cmd
. It's set now as an example to a dropbox folder as suggested above.
Windows Registry Editor Version 5.00
[HKEY_CURRENT_USER\Software\Microsoft\Command Processor]
"AutoRun"="%USERPROFILE%\\alias.cmd"
For single-user applications, the above will do. Nevertheless, there are situations where it is necessary to check whether alias.cmd
exists first in the registry key. See example below.
In a C:\Users\Public\init.cmd
file hosting potentially cross-user configurations:
@ECHO OFF
REM Add other configurations as needed
IF EXIST "%USERPROFILE%\alias.cmd" ( CALL "%USERPROFILE%\alias.cmd" )
The registry key should be updated correspondly to C:\Users\Public\init.cmd
or, using the .reg
file:
Windows Registry Editor Version 5.00
[HKEY_CURRENT_USER\Software\Microsoft\Command Processor]
"AutoRun"="C:\\Users\\Public\\init.cmd"
Setting the CurrentCell
and then calling BeginEdit(true)
works well for me.
The following code shows an eventHandler for the KeyDown
event that sets a cell to be editable.
My example only implements one of the required key press overrides but in theory the others should work the same. (and I'm always setting the [0][0] cell to be editable but any other cell should work)
private void dataGridView1_KeyDown(object sender, KeyEventArgs e)
{
if (e.KeyCode == Keys.Tab && dataGridView1.CurrentCell.ColumnIndex == 1)
{
e.Handled = true;
DataGridViewCell cell = dataGridView1.Rows[0].Cells[0];
dataGridView1.CurrentCell = cell;
dataGridView1.BeginEdit(true);
}
}
If you haven't found it previously, the DataGridView FAQ is a great resource, written by the program manager for the DataGridView control, which covers most of what you could want to do with the control.
add this to ~/.bashrc:
function mkfile() {
mkdir -p "$1" && touch "$1"/"$2"
}
save and then to make it available without a reboot or logout execute: $ source ~/.bashrc
or you can just do:
$ mkdir folder && touch $_/file.txt
note that $_ = folder
How about something like this, which is O(n^2)
for(each ele in the sorted array)
{
ele = arr[i] - YOUR_NUMBER;
let front be the pointer to the front of the array;
let rear be the pointer to the rear element of the array.;
// till front is not greater than rear.
while(front <= rear)
{
if(*front + *rear == ele)
{
print "Found triplet "<<*front<<","<<*rear<<","<<ele<<endl;
break;
}
else
{
// sum is > ele, so we need to decrease the sum by decrementing rear pointer.
if((*front + *rear) > ele)
decrement rear pointer.
// sum is < ele, so we need to increase the sum by incrementing the front pointer.
else
increment front pointer.
}
}
This finds if sum of 3 elements is exactly equal to your number. If you want closest, you can modify it to remember the smallest delta(difference between your number of current triplet) and at the end print the triplet corresponding to smallest delta.
I consider that the most Pythonic way is to use a list comprehension instead of map
and filter
. The reason is that list comprehensions are clearer than map
and filter
.
In [1]: odd_cubes = [x ** 3 for x in range(10) if x % 2 == 1] # using a list comprehension
In [2]: odd_cubes_alt = list(map(lambda x: x ** 3, filter(lambda x: x % 2 == 1, range(10)))) # using map and filter
In [3]: odd_cubes == odd_cubes_alt
Out[3]: True
As you an see, a comprehension does not require extra lambda
expressions as map
needs. Furthermore, a comprehension also allows filtering easily, while map
requires filter
to allow filtering.
You should use the current sys
catalog views (if you're on SQL Server 2005 or newer - the sysobjects
views are deprecated and should be avoided) - check out the extensive MSDN SQL Server Books Online documentation on catalog views here.
There are quite a few views you might be interested in:
sys.default_constraints
for default constraints on columnssys.check_constraints
for check constraints on columnssys.key_constraints
for key constraints (e.g. primary keys)sys.foreign_keys
for foreign key relationsand a lot more - check it out!
You can query and join those views to get the info needed - e.g. this will list the tables, columns and all default constraints defined on them:
SELECT
TableName = t.Name,
ColumnName = c.Name,
dc.Name,
dc.definition
FROM sys.tables t
INNER JOIN sys.default_constraints dc ON t.object_id = dc.parent_object_id
INNER JOIN sys.columns c ON dc.parent_object_id = c.object_id AND c.column_id = dc.parent_column_id
ORDER BY t.Name
printf() doesn't directly support that. Instead you have to make your own function.
Something like:
while (n) {
if (n & 1)
printf("1");
else
printf("0");
n >>= 1;
}
printf("\n");
Depends a lot on your definition of what a "character" is. If "rune equals a character " is OK for your task (generally it isn't) then the answer by VonC is perfect for you. Otherwise, it should be probably noted, that there are few situations where the number of runes in a Unicode string is an interesting value. And even in those situations it's better, if possible, to infer the count while "traversing" the string as the runes are processed to avoid doubling the UTF-8 decode effort.
If you are adding integers, as you say in your question, this will add 50 (from 1 to 50):
for (int x = 1; x <= 50; x++)
{
list.Items.Add(x);
}
You do not need to set DisplayMember and ValueMember unless you are adding objects that have specific properties that you want to display to the user. In your example:
listbox1.Items.Add(new { clan = "Foo", sifOsoba = 1234 });
So, the answers here are all a bit incomplete. The use of a '%20' to encode a space in URLs is explicitly defined in RFC3986, which defines how a URI is built. There is no mention in this specification of using a '+' for encoding spaces - if you go solely by this specification, a space must be encoded as '%20'.
The mention of using '+' for encoding spaces comes from the various incarnations of the HTML specification - specifically in the section describing content type 'application/x-www-form-urlencoded'. This is used for posting form data.
Now, the HTML 2.0 Specification (RFC1866) explicitly said, in section 8.2.2, that the Query part of a GET request's URL string should be encoded as 'application/x-www-form-urlencoded'. This, in theory, suggests that it's legal to use a '+' in the URL in the query string (after the '?').
But... does it really? Remember, HTML is itself a content specification, and URLs with query strings can be used with content other than HTML. Further, while the later versions of the HTML spec continue to define '+' as legal in 'application/x-www-form-urlencoded' content, they completely omit the part saying that GET request query strings are defined as that type. There is, in fact, no mention whatsoever about the query string encoding in anything after the HTML 2.0 spec.
Which leaves us with the question - is it valid? Certainly there's a LOT of legacy code which supports '+' in query strings, and a lot of code which generates it as well. So odds are good you won't break if you use '+'. (And, in fact, I did all the research on this recently because I discovered a major site which failed to accept '%20' in a GET query as a space. They actually failed to decode ANY percent encoded character. So the service you're using may be relevant as well.)
But from a pure reading of the specifications, without the language from the HTML 2.0 specification carried over into later versions, URLs are covered entirely by RFC3986, which means spaces ought to be converted to '%20'. And definitely that should be the case if you are requesting anything other than an HTML document.
https://github.com/IdentityModel/IdentityModel adds extensions to HttpClient
to acquire tokens using different flows and the documentation is great too. It's very handy because you don't have to think how to implement it yourself. I'm not aware if any official MS implementation exists.

In case it helps someone else, I was able to convert to an array by doing something like this,
JSONObject jsonObject = (JSONObject)new JSONParser().parse(jsonString);
((JSONArray) jsonObject).toArray()
...or you should be able to get the length
((JSONArray) myJsonArray).toArray().length
As MrFancypants mentioned in the comments, if you are using Jupyter (which you should, since it currently supersedes the older IPython Notebook project), things are a little different. For one, there are no profiles any more.
After installing Jupyter, first check your ~/.jupyter folder to see its content. If no config files were migrated from the default IPython profile (as they weren't in my case), create a new one for Jupyter Notebook:
jupyter notebook --generate-config
This generates ~/.jupyter/jupyter_notebook_config.py file with some helpfully commented possible options. To set the default directory add:
c.NotebookApp.notebook_dir = u'/absolute/path/to/notebook/directory'
As I switch between Linux and OS X, I wanted to use a path relative to my home folder (as they differ – /Users/username and /home/username), so I set something like:
import os
c.NotebookApp.notebook_dir = os.path.expanduser('~/Dropbox/dev/notebook')
Now, whenever I run jupyter notebook
, it opens my desired notebook folder. I also version the whole ~/.jupyter folder in my dotfiles repository that I deploy to every new work machine.
As an aside, you can still use the --notebook-dir
command line option, so maybe a simple alias would suit your needs better.
jupyter notebook --notebook-dir=/absolute/path/to/notebook/directory
You can simply use (char) System.in.read();
casting to char
is necessary to convert int
to char
You can do this in one line, using the conditional operator and the fact that you can cast null
to a nullable type (two lines, if you don't have a pre-existing int you can reuse for the output of TryParse
):
Pre C#7:
int tempVal;
int? val = Int32.TryParse(stringVal, out tempVal) ? Int32.Parse(stringVal) : (int?)null;
With C#7's updated syntax that allows you to declare an output variable in the method call, this gets even simpler.
int? val = Int32.TryParse(stringVal, out var tempVal) ? tempVal : (int?)null;
I'm making a guess, but if you want an actual handshake to occur, you have to let android know of your certificate. If you want to just accept no matter what, then use this pseudo-code to get what you need with the Apache HTTP Client:
SchemeRegistry schemeRegistry = new SchemeRegistry ();
schemeRegistry.register (new Scheme ("http",
PlainSocketFactory.getSocketFactory (), 80));
schemeRegistry.register (new Scheme ("https",
new CustomSSLSocketFactory (), 443));
ThreadSafeClientConnManager cm = new ThreadSafeClientConnManager (
params, schemeRegistry);
return new DefaultHttpClient (cm, params);
CustomSSLSocketFactory:
public class CustomSSLSocketFactory extends org.apache.http.conn.ssl.SSLSocketFactory
{
private SSLSocketFactory FACTORY = HttpsURLConnection.getDefaultSSLSocketFactory ();
public CustomSSLSocketFactory ()
{
super(null);
try
{
SSLContext context = SSLContext.getInstance ("TLS");
TrustManager[] tm = new TrustManager[] { new FullX509TrustManager () };
context.init (null, tm, new SecureRandom ());
FACTORY = context.getSocketFactory ();
}
catch (Exception e)
{
e.printStackTrace();
}
}
public Socket createSocket() throws IOException
{
return FACTORY.createSocket();
}
// TODO: add other methods like createSocket() and getDefaultCipherSuites().
// Hint: they all just make a call to member FACTORY
}
FullX509TrustManager is a class that implements javax.net.ssl.X509TrustManager, yet none of the methods actually perform any work, get a sample here.
Good Luck!
From version 2.13.0
of Dart Code, emulators can be launched directly from within Code but This feature relies on support from the Flutter tools which means it will only show emulators when using a very recent Flutter SDK. Flutter’s master channel already has this change, but it may take a little longer to filter through to the dev and beta channels.
I tested this feature and worked very well on flutter version 0.5.6-pre.61 (master channel)

size_t
and int
are not interchangeable. For instance on 64-bit Linux size_t
is 64-bit in size (i.e. sizeof(void*)
) but int
is 32-bit.
Also note that size_t
is unsigned. If you need signed version then there is ssize_t
on some platforms and it would be more relevant to your example.
As a general rule I would suggest using int
for most general cases and only use size_t
/ssize_t
when there is a specific need for it (with mmap()
for example).
That's all. You can see progression of build in left below corner.
print "Number of lines: $nids\n";
print "Content: $ids\n";
How did Perl complain? print $ids
should work, though you probably want a newline at the end, either explicitly with print
as above or implicitly by using say
or -l/$\.
If you want to interpolate a variable in a string and have something immediately after it that would looks like part of the variable but isn't, enclose the variable name in {}
:
print "foo${ids}bar";

A comment about Will's answer, you might want to replace HttpContext.Current.Response.End();
with HttpContext.Current.ApplicationInstance.CompleteRequest();
The reason is that Response.End()
throws a System.Threading.ThreadAbortException
. It aborts a thread. If you have an exception logger, it will be littered with ThreadAbortExceptions, which in this case is expected behavior.
Intuitively, sending a CSV file to the browser should not raise an exception.

edit (not by the author): There is a comprehensive list of IoC frameworks available at https://github.com/quozd/awesome-dotnet/blob/master/README.md#ioc:
Original answer follows.
I suppose I might be being a bit picky here but it's important to note that DI (Dependency Injection) is a programming pattern and is facilitated by, but does not require, an IoC (Inversion of Control) framework. IoC frameworks just make DI much easier and they provide a host of other benefits over and above DI.
That being said, I'm sure that's what you were asking. About IoC Frameworks; I used to use Spring.Net and CastleWindsor a lot, but the real pain in the behind was all that pesky XML config you had to write! They're pretty much all moving this way now, so I have been using StructureMap for the last year or so, and since it has moved to a fluent config using strongly typed generics and a registry, my pain barrier in using IoC has dropped to below zero! I get an absolute kick out of knowing now that my IoC config is checked at compile-time (for the most part) and I have had nothing but joy with StructureMap and its speed. I won't say that the others were slow at runtime, but they were more difficult for me to setup and frustration often won the day.
Update
I've been using Ninject on my latest project and it has been an absolute pleasure to use. Words fail me a bit here, but (as we say in the UK) this framework is 'the Dogs'. I would highly recommend it for any green fields projects where you want to be up and running quickly. I got all I needed from a fantastic set of Ninject screencasts by Justin Etheredge. I can't see that retro-fitting Ninject into existing code being a problem at all, but then the same could be said of StructureMap in my experience. It'll be a tough choice going forward between those two, but I'd rather have competition than stagnation and there's a decent amount of healthy competition out there.
Other IoC screencasts can also be found here on Dimecasts.
What if you don't want to commit every commit that you make in Git, to the SVN repository? What if you just want to selectively send commits up the pipe? Well, I have a better solution.
I keep one local Git repository where all I ever do is fetch and merge from SVN. That way I can make sure I'm including all the same changes as SVN, but I keep my commit history separate from the SVN entirely.
Then I keep a separate SVN local working copy that is in a separate folder. That's the one I make commits back to SVN from, and I simply use the SVN command line utility for that.
When I'm ready to commit my local Git repository's state to SVN, I simply copy the whole mess of files over into the local SVN working copy and commit it from there using SVN rather than Git.
This way I never have to do any rebasing, because rebasing is like freebasing.

let canvasBox = ReactDOM.findDOMNode(this.refs.canvasBox);
let width = canvasBox.clientWidth;
let height = canvasBox.clientHeight;
let charts = ReactDOM.findDOMNode(this.refs.charts);
let ctx = charts.getContext('2d');

ctx.canvas.height = height;
this.myChart = new Chart(ctx);
One issue that I've come across is that to have a scrollbar a n element needs a height to be specified (and not as a %).
The trick is to nest another set of divs within each column, and set the column parent's display to flex with flex-direction: column.
<style>
html, body {
height: 100%;
margin: 0;
padding: 0;
}

overflow-y: hidden;
overflow-x: hidden;

}
.base-container {
display: flex;
flex: 1;
flex-direction: column;
width: 100%;
height: 100%;
overflow-y: hidden;
align-items: stretch;
}
.title {
flex: 0 0 50px;
color: black;
}
.container {
flex: 1 1 auto;
display: flex;
flex-direction: column;
}
.container .header {
flex: 0 0 50px;
background-color: red;
}
.container .body {
flex: 1 1 auto;
display: flex;
flex-direction: row;
}
.container .body .left {
display: flex;
flex-direction: column;

}
.container .body .main .content.noscrollbar {
overflow-y: hidden;
}
.container .body .main {

In C++, the ability to create a protected abstract virtual base pure virtual private destructor.
This is a pure virtual private destructor that is inherited from a protected abstract virtual base.
IOW, a destructor that can only be called by members or friends of the class (private), and which is assigned a 0 (pure virtual) in the base class (abstract base) that declares it, and which will be defined later/overriden in a derived class that shares the multiple-inherited base (virtual base) in a protected way.
I would suggest:
function onChange(field){
field.old=field.recent;
field.recent=field.value;
//we have available old value here;
}
First off, run
npm init
...will ask you a few questions (read this first) about your project/package and then generate a package.json file for you.
Then, once you have a package.json file, use
npm install <pkg> --save
or
npm install <pkg> --save-dev
...to install a dependency and automatically append it to your package.json
's dependencies
list.
(Note: You may need to manually tweak the version ranges for your dependencies.)

Yes, in order for the z-index
to work, you'll need to give the element a position: absolute
or a position: relative
property.
You have to go up the nodes of the elements to check if at the level of the common parent the first descendants have a defined z-index.
All other descendants can never be in the foreground if at the base there is a lower definite z-index
.
In this snippet example, div1-2-1
has a z-index
of 1000 but is nevertheless under the div1-1-1
which has a z-index of 3.
This is because div1-1 has a z-index greater than div1-2.

I think the main complaints about sqlite scaling is:
You can clone the module directly in to your local project.
Start terminal. cd in to your project and then:
npm install https://github.com/repo/npm_module.git --save
Just a hint... think twice before using "transform: rotate()", or even "-ms-transform :rotate()" (IE9) with mobiles!
I've been knocking hard to the wall for days. I have a 'kinetic' system going on, that slides images and, on top of it, a command area. I did "transform" on an arrow button so it simulates pointing up and down... I've reviewd the 1.000 plus code lines for ages!!! ;-)
All ok, once I removed transform:rotate from the CSS. It's a bit (not to use bad words) tricky the way IE handles it, comparing to other borwsers.
Great answer @Spudley! Thanks for writing it!

savefig
specifies the DPI for the saved figure (The default is 100 if it's not specified in your .matplotlibrc, have a look at the dpi
kwarg to savefig
). It doesn't inheret it from the DPI of the original figure.
The DPI affects the relative size of the text and width of the stroke on lines, etc. If you want things to look identical, then pass fig.dpi
to fig.savefig
.
E.g.
import matplotlib.pyplot as plt
fig = plt.figure()
plt.plot(range(10))
fig.savefig('temp.png', dpi=fig.dpi)
Add
background-size:100% 100%;
to your css underneath background-image.
You can also specify exact dimensions, i.e.:
background-size: 30px 40px;

Depending on what you are doing, it could make sense to define a decorator
, or perhaps use functools.partial
.
You are getting arithmetic overflow. this means you are trying to make a conversion impossible to be made. This error is thrown when you try to make a conversion and the destiny data type is not enough to convert the origin data. For example:
If you try to convert 100.52 to decimal(4,2) you will get this error. The number 100.52 requires 5 positions and 2 of them are decimal.
Try to change the decimal precision to something like 16,2 or higher. Try with few records first then use it to all your select.
Run Visual Studio as Administrator and put your SQL SERVER authentication login (who has the permission to create a DB) and password in the connection string, it worked for me
This is an old question but it has a high view count, so I think some new information should be added: In the mean time a lot has changed, and you can now also use Microsoft's own .NET Core on linux. It's also available in ARM builds, 32 and 64 bit.
You can use negated character classes to exclude certain characters: for example [^abcde]
will match anything but a,b,c,d,e characters.
Instead of specifying all the characters literally, you can use shorthands inside character classes: [\w]
(lowercase) will match any "word character" (letter, numbers and underscore), [\W]
(uppercase) will match anything but word characters; similarly, [\d]
will match the 0-9 digits while [\D]
matches anything but the 0-9 digits, and so on.
If you use PHP you can take a look at the regex character classes documentation.
Simpler with the aggregate function string_agg()
(Postgres 9.0 or later):
SELECT movie, string_agg(actor, ', ') AS actor_list
FROM tbl
GROUP BY 1;
The 1
in GROUP BY 1
is a positional reference and a shortcut for GROUP BY movie
in this case.
string_agg()
expects data type text
as input. Other types need to be cast explicitly (actor::text
) - unless an implicit cast to text
is defined - which is the case for all other character types (varchar
, character
, "char"
), and some other types.
As isapir commented, you can add an ORDER BY
clause in the aggregate call to get a sorted list - should you need that. Like:
SELECT movie, string_agg(actor, ', ' ORDER BY actor) AS actor_list
FROM tbl
GROUP BY 1;
But it's typically faster to sort rows in a subquery. See:
<?xml version="1.0" encoding="UTF-8"?>

<Appenders>
<Console name="Console" target="SYSTEM_OUT">
<PatternLayout pattern="%d{HH:mm:ss.SSS} [%t] %-5level %logger{36} - %msg%n" />

Notes:
Logger logger = LogManager.getLogger();
to initialize your loggerWith Java 8 you can simply convert your list to a stream allowing you to write:
import java.util.List;
import java.util.stream.Collectors;
List<Sample> list = new ArrayList<Sample>();
List<Sample> result = list.stream()
.filter(a -> Objects.equals(a.value3, "three"))
.collect(Collectors.toList());
Note that
a -> Objects.equals(a.value3, "three")
is a lambda expressionresult
is a List
with a Sample
typelist.parallelStream()
instead of list.stream()
(read this)If you can't use Java 8, you can use Apache Commons library and write:
import org.apache.commons.collections.CollectionUtils;
import org.apache.commons.collections.Predicate;
Collection result = CollectionUtils.select(list, new Predicate() {
public boolean evaluate(Object a) {
return Objects.equals(((Sample) a).value3, "three");
}
});
// If you need the results as a typed array:
Sample[] resultTyped = (Sample[]) result.toArray(new Sample[result.size()]);
Note that:
Object
to Sample
at each iterationSample[]
, you need extra code (as shown in my sample)Bonus: A nice blog article talking about how to find element in list.
SQl Management Studio data import looks at the first few rows to determine source data specs..

If you don't want to jQuery, here's the vanilla JavaScript:
///Mute
var video = document.getElementById("your-video-id");
video.muted= true;
//Unmute
var video = document.getElementById("your-video-id");
video.muted= false;
It will work for audio too, just put the element's id and it will work (and change the var name if you want, to 'media' or something suited for both audio/video as you like).
The thing on the right of <-
is a formula
object. It is often used to denote a statistical model, where the thing on the left of the ~
is the response and the things on the right of the ~
are the explanatory variables. So in English you'd say something like "Species depends on Sepal Length, Sepal Width, Petal Length and Petal Width".
The myFormula <-
part of that line stores the formula in an object called myFormula
so you can use it in other parts of your R code.
Other common uses of formula objects in R
The lattice
package uses them to specify the variables to plot.
The ggplot2
package uses them to specify panels for plotting.
The dplyr
package uses them for non-standard evaulation.
I would suggest a more lightweight approach for traversing the complete responder chain without having to add a category on UIView:
@implementation MyUIViewSubclass
- (UIViewController *)viewController {
UIResponder *responder = self;
while (![responder isKindOfClass:[UIViewController class]]) {
responder = [responder nextResponder];
if (nil == responder) {
break;
}
}
return (UIViewController *)responder;
}
@end
Here is one way of getting the design that you want.
Start with the following HTML:
<div class="container">
<div class="row-fluid">
<div class="span12">
<div class="nav">nav area</div>
<div class="bg-image">
<img src="http://unplugged.ee/wp-content/uploads/2013/03/frank2.jpg">
<h1>This is centered text.</h1>
</div>
<div class="main">main area</div>
</div>
</div>
</div>
Note that the background image is now part of the regular flow of the document.
Apply the following CSS:
.bg-image {
position: relative;
}
.bg-image img {
display: block;
width: 100%;
max-width: 1200px; /* corresponds to max height of 450px */
margin: 0 auto;
}
.bg-image h1 {
position: absolute;
text-align: center;
bottom: 0;
left: 0;
right: 0;
color: white;
}
.nav, .main {
background-color: #f6f6f6;
text-align: center;
}
The image is set an regular flow content with a width of 100%, so it will adjust itself responsively to the width of the parent container. However, you want the height to be no more than 450px, which corresponds to the image width of 1200px, so set the maximum width of the image to 1200px. You can keep the image centered by using display: block
and margin: 0 auto
.
The text is painted over the image by using absolute positioning. In the simplest case, I stretch the h1
element to be the full width of the parent and use text-align: center
to center the text. Use the top or bottom offsets to place the text where it is needed.
If your banner images are going to vary in aspect ratio, you will need to adjust the maximum width value for .bg-image img
dynamically using jQuery/Javascript, but otherwise, this approach has a lot to offer.
See demo at: http://jsfiddle.net/audetwebdesign/EGgaN/
scale(..)
works a bit differently. You can use bufferedImage.getScaledInstance(..)
I found some trick for your problem! Here you can see it: Habrahabr -- Redesigning Qt Creator by your hands (russian lang.)
According to that article, that trick is kind of not so dirty, but "hack" (probably it wouldn't harm your system, but it can leave some artifacts on your interface).
You don't need to patch something (there is possibility, but I don't recommend).
Main idea is to use stylesheet like this stylesheet.css:
// on Linux
qtcreator -stylesheet='.qt-stylesheet.css'
// on Windows
[pathToQt]\QtCreator\bin\qtcreator.exe -stylesheet [pathToStyleSheet]
To get such effect:
To customize by your needs, you may need to read documentation: Qt Style Sheets Reference, Qt Style Sheets Examples and so on.
This wiki page is dedicated to custom Qt Creator styling.
P.S. If you'll got better stylesheet, share it, I'll be happy! :)
UPD (10.12.2014): Hopefully, now we can close this topic. Thanks, Simon G., Things have changed once again. Users may use custom themes since QtCreator 3.3. So hacky stylesheets are no longer needed.
Everyone can take a look at todays update: Qt 5.4 released. There you can find information that Qt 5.4, also comes with a brand new version of Qt Creator 3.3. Just take a look at official video at Youtube.
So, to apply dark theme you need go to "Tools" -> "Options" -> "Environment" -> "General" tab, and there you need to change "Theme".
See more information about its configuring here: Configuring Qt Creator.
An example of an associated full GC also shows the collectors used for the old and permanent generations:
3.757: [Full GC [PSYoungGen: 2672K->0K(35584K)]
[ParOldGen: 3225K->5735K(43712K)] 5898K->5735K(79296K)
[PSPermGen: 13533K->13516K(27584K)], 0.0860402 secs]
Finally, breaking down one line of your example log output:
8109.128: [GC [PSYoungGen: 109884K->14201K(139904K)] 691015K->595332K(1119040K), 0.0454530 secs]
When the shape is not regular or the elements have different data types, the dtype
argument passed to np.array only can be object
.
import numpy as np
# arr1 = np.array([[10, 20.], [30], [40]], dtype=np.float32) # error
arr2 = np.array([[10, 20.], [30], [40]]) # OK, and the dtype is object
arr3 = np.array([[10, 20.], 'hello']) # OK, and the dtype is also object

There is a React module called react-client-session
that makes storing client side session data very easy. The git repo is here.
This is implemented in a similar way as the closure approach in my other answer, however it also supports persistence using 3 different persistence stores. The default store is memory(not persistent).
After installing, just set the desired store type where you mount the root component ...
import ReactSession from 'react-client-session';
ReactSession.setStoreType("localStorage");
... and set/get key value pairs from anywhere in your app:
import ReactSession from 'react-client-session';
ReactSession.set("username", "Bob");
ReactSession.get("username"); // Returns "Bob"
import java.util.ArrayList;
import java.util.List;
class ArrLst{
public static void main(String args[]){
List l=new ArrayList();
l.add(10);
l.add(11);
l.add(12);
l.add(13);
l.add(14);
l.forEach((a)->System.out.println(a));
}
}
I have encountered such a problem when grouping object, i always resolved them by a simple way: perform a custom filter using a java.util.Set to remove duplicate object with whatever attribute of your choice as bellow
Set<String> uniqueNames = new HashSet<>();
Map<String, String> phoneBook = people
.stream()
.filter(person -> person != null && !uniqueNames.add(person.getName()))
.collect(toMap(Person::getName, Person::getAddress));
Hope this helps anyone having the same problem !
In my case, it happened after installing Microsoft Web Matrix. Uninstalling this trash along with "Microsoft Web Deploy" fixed the issue.

This is the best and easiest code:
public class test

String jsonString = "{\"stat\": { \"sdr\": \"aa:bb:cc:dd:ee:ff\", \"rcv\": \"aa:bb:cc:dd:ee:ff\", \"time\": \"UTC in millis\", \"type\": 1, \"subt\": 1, \"argv\": [{\"type\": 1, \"val\":\"stackoverflow\"}]}}";
JSONObject jsonObject = new JSONObject(jsonString);
JSONObject newJSON = jsonObject.getJSONObject("stat");
System.out.println(newJSON.toString());
jsonObject = new JSONObject(newJSON.toString());
System.out.println(jsonObject.getString("rcv"));
System.out.println(jsonObject.getJSONArray("argv"));
}
}
The library definition of the json files are given here. And it is not same libraries as posted here, i.e. posted by you. What you had posted was simple json library I have used this library.
You can download the zip. And then create a package
in your project with org.json as name. and paste all the downloaded codes there, and have fun.
I feel this to be the best and the most easiest JSON Decoding.

node-byline uses streams, so i would prefer that one for your huge files.
for your date-conversions i would use moment.js.
for maximising your throughput you could think about using a software-cluster. there are some nice-modules which wrap the node-native cluster-module quite well. i like cluster-master from isaacs. e.g. you could create a cluster of x workers which all compute a file.
for benchmarking splits vs regexes use benchmark.js. i havent tested it until now. benchmark.js is available as a node-module

Here's the general idea:
Get child items in the .NET Framework directory that are containers whose names match the pattern v number dot number. Sort them by descending name, take the first object, and return its name property.
Here's the script:
(Get-ChildItem -Path $Env:windir\Microsoft.NET\Framework | Where-Object {$_.PSIsContainer -eq $true } | Where-Object {$_.Name -match 'v\d\.\d'} | Sort-Object -Property Name -Descending | Select-Object -First 1).Name
Disclaimer: I first wrote this and then stumbled upon this question. I thought this solution wasn't yet posted, and saw that tlwhitec did post a similar answer. Still I'm posting this because I hope it's a useful and thorough explanation.
Short answer:
This seems quite a portable solution, as it works on quite some shells (see comment).
This way you can get a real newline into a variable.
The benefit of this solution is that you don't have to use newlines in your source code, so you can indent your code any way you want, and the solution still works. This makes it robust. It's also portable.
# Robust way to put a real newline in a variable (bash, dash, ksh, zsh; indentation-resistant).
nl="$(printf '\nq')"
nl=${nl%q}
Longer answer:
Explanation of the above solution:
The newline would normally lost due to command substitution, but to prevent that, we add a 'q' and remove it afterwards. (The reason for the double quotes is explained further below.)
We can prove that the variable contains an actual newline character (0x0A):
printf '%s' "$nl" | hexdump -C
00000000 0a |.|
00000001
(Note that the '%s'
was needed, otherwise printf will translate a literal '\n'
string into an actual 0x0A character, meaning we would prove nothing.)
Of course, instead of the solution proposed in this answer, one could use this as well (but...):
nl='
'
... but that's less robust and can be easily damaged by accidentally indenting the code, or by forgetting to dedent it afterwards, which makes it inconvenient to use in (indented) functions, whereas the earlier solution is robust.
Now, as for the double quotes:
The reason for the double quotes "
surrounding the command substitution as in nl="$(printf '\nq')"
is that you can then even prefix the variable assignment with the local
keyword or builtin (such as in functions), and it will still work on all shells, whereas otherwise the dash
shell would have trouble, in the sense that dash would otherwise lose the 'q' and you'd end up with an empty 'nl' variable (again, due to command substitution).
That issue is better illustrated with another example:
dash_trouble_example() {
e=$(echo hello world) # Not using 'local'.
echo "$e" # Fine. Outputs 'hello world' in all shells.
local e=$(echo hello world) # But now, when using 'local' without double quotes ...:
echo "$e" # ... oops, outputs just 'hello' in dash,
# ... but 'hello world' in bash and zsh.
local f="$(echo hello world)" # Finally, using 'local' and surrounding with double quotes.
echo "$f" # Solved. Outputs 'hello world' in dash, zsh, and bash.
# So back to our newline example, if we want to use 'local', we need
# double quotes to surround the command substitution:
# (If we didn't use double quotes here, then in dash the 'nl' variable
# would be empty.)
local nl="$(printf '\nq')"
nl=${nl%q}
}
Practical example of the above solution:
# Parsing lines in a for loop by setting IFS to a real newline character:
nl="$(printf '\nq')"
nl=${nl%q}
IFS=$nl
for i in $(printf '%b' 'this is line 1\nthis is line 2'); do
echo "i=$i"
done
# Desired output:
# i=this is line 1
# i=this is line 2
# Exercise:
# Try running this example without the IFS=$nl assignment, and predict the outcome.
Inspired by Simon Mattes' answer, I needed to satisfy IHttpActionResult required return type of ResponseMessageResult. Also using nashawn's JsonContent, I ended up with...
return new System.Web.Http.Results.ResponseMessageResult(
new System.Net.Http.HttpResponseMessage(System.Net.HttpStatusCode.OK)
{
Content = new JsonContent(JsonConvert.SerializeObject(contact, Formatting.Indented))
});
See nashawn's answer for JsonContent.
This is Stack Overflow so I assume you want code:
All following code assumes that you want to create a symbolic link named /tmp/link
that links to /tmp/realfile
.
CAUTION: Although this code checks for errors, it does NOT check if /tmp/realfile
actually exists ! This is because a dead link is still valid and depending on your code you might (rarely) want to create the link before the real file.
#!/bin/sh
ln -s /tmp/realfile /tmp/link
Real simple, just like you would do it on the command line (which is the shell). All error handling is done by the shell interpreter. This code assumes that you have a working shell interpreter at /bin/sh
.
If needed you could still implement your own error handling by using the $?
variable which will only be set to 0 if the link was successfully created.
#include <unistd.h>
#include <stdio.h>
int main () {
if( symlink("/tmp/realfile", "/tmp/link") != 0 )
perror("Can't create the symlink");
}
symlink
only returns 0 when the link can be created. In other cases I'm using perror
to tell more about the problem.
#!/usr/bin/perl
if( symlink("/tmp/realfile", "/tmp/link") != 1) {
print STDERR "Can't create the symlink: $!\n"
}
This code assumes you have a perl 5 interpreter at /usr/bin/perl
. symlink
only returns 1 if the link can be created. In other cases I'm printing the failure reason to the standard error output.
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);
}
The error "Cannot read property 'map' of undefined"
will be encountered if there is an error in the "this.props.data"
or there is no props.data array.
Better put condition to check the the array like
if(this.props.data){
this.props.data.map(........)
.....
}
Is this the kind of thing you want? You might want to extend it to get more info out of the sys tables.
use master DECLARE @name VARCHAR(50) -- database name DECLARE db_cursor CURSOR FOR select name from sys.databases OPEN db_cursor FETCH NEXT FROM db_cursor INTO @name WHILE @@FETCH_STATUS = 0 BEGIN print @name exec('USE ' + @name + '; select rp.name, mp.name from sys.database_role_members drm join sys.database_principals rp on (drm.role_principal_id = rp.principal_id) join sys.database_principals mp on (drm.member_principal_id = mp.principal_id)') FETCH NEXT FROM db_cursor INTO @name END CLOSE db_cursor DEALLOCATE db_cursor
The safest way is to rely on the browser TextNode to correctly escape content. Here's an example:
function stripHTML(dirtyString) {_x000D_
var container = document.createElement('div');_x000D_
var text = document.createTextNode(dirtyString);_x000D_
container.appendChild(text);_x000D_
return container.innerHTML; // innerHTML will be a xss safe string_x000D_
}_x000D_
_x000D_
document.write( stripHTML('<p>some <span>content</span></p>') );_x000D_
document.write( stripHTML('<script><p>some <span>content</span></p>') );
_x000D_
The thing to remember here is that the browser escape the special characters of TextNodes when we access the html strings (innerHTML
, outerHTML
). By comparison, accessing text values (innerText
, textContent
) will yield raw strings, meaning they're unsafe and could contains XSS.
If you use jQuery, then using .text()
is safe and backward compatible. See the other answers to this question.
The simplest way in pure JavaScript if you work with browsers <= Internet Explorer 8 is:
string.replace(/(<([^>]+)>)/ig,"");
But there's some issue with parsing HTML with regex so this won't provide very good security. Also, this only takes care of HTML characters, so it is not totally xss-safe.
POD classes are Plain-Old data classes that have only data members and nothing else. There are a few questions on stackoverflow about the same. Find one here.
Also, you can have functions as members of structs in C++ but not in C. You need to have pointers to functions as members in structs in C.
Using the Excel Text import wizard to import it if it is a text file, like a CSV file, is another option and can be done based on which row number to which row numbers you specify. See: This link
Select
Count(Distinct user_id) As countUsers
, Count(site_id) As countVisits
, site_id As site
From cp_visits
Where ts >= DATE_SUB(NOW(), INTERVAL 1 DAY)
Group By site_id
DateTime.Today.ToString("MM/dd/yy")
Look at the docs for custom date and time format strings for more info.
(Oh, and I hope this app isn't destined for other cultures. That format could really confuse a lot of people... I've never understood the whole month/day/year thing, to be honest. It just seems weird to go "middle/low/high" in terms of scale like that.)
If you need to distribute your .jar file and make it runnable at other people's Windows computers, you can make a simple .bat file like this in the command prompt:
java -jar MyJavaTool.jar
and place the .bat file in the same directory as your .jar file.
I always put my scripts in the header. My reasons:
Assuming you are on Python 3, you can use this syntax
inputs = list(map(str,input().split()))
if you want to access individual element you can do it like that
m, n = map(str,input().split())
I think you need a body for the getAppContext()
method:
public static Context getAppContext()
return MyApplication.context;
TextView tv = new TextView(this);
tv.setText(String.valueOf(number));
or
tv.setText(""+number);
Comparing non-primitives (aka Objects) in Java with ==
compares their reference instead of their values. Long
is a class and thus Long
values are Objects.
The problem is that the Java Developers wanted people to use Long
like they used long
to provide compatibility, which led to the concept of autoboxing, which is essentially the feature, that long
-values will be changed to Long
-Objects and vice versa as needed. The behaviour of autoboxing is not exactly predictable all the time though, as it is not completely specified.
So to be safe and to have predictable results always use .equals()
to compare objects and do not rely on autoboxing in this case:
Long num1 = 127, num2 = 127;
if(num1.equals(num2)) { iWillBeExecutedAlways(); }
The best thing you can do is leave out the action attribute altogether. If you leave it out, the form will be submitted to the document's address, i.e. the same page.
It is also possible to leave it empty, and any browser implementing HTML's form submission algorithm will treat it as equivalent to the document's address, which it does mainly because that's how browsers currently work:
8.
Let action be the submitter element's action.
9.
If action is the empty string, let action be the document's address.Note: This step is a willful violation of RFC 3986, which would require base URL processing here. This violation is motivated by a desire for compatibility with legacy content. [RFC3986]
This definitely works in all current browsers, but may not work as expected in some older browsers ("browsers do weird things with an empty action="" attribute"), which is why the spec strongly discourages authors from leaving it empty:
The
action
andformaction
content attributes, if specified, must have a value that is a valid non-empty URL potentially surrounded by spaces.

The built-in iter function does specifically that:
for x in iter(YOUR_FN, TERM_VAL):
...
E.g. (tested in Py2 and 3):
class Easy:
X = 0
@classmethod
def com(cls):
cls.X += 1
return cls.X
for x in iter(Easy.com, 10):
print(">>>", x)
If you want to give a condition to terminate instead of a value, you always can set an equality, and require that equality to be True
.
JQuery is looking for a json type result, but because the redirect is processed automatically, it will receive the generated html source of your login.htm
page.
One idea is to let the the browser know that it should redirect by adding a redirect
variable to to the resulting object and checking for it in JQuery:
$(document).ready(function(){
jQuery.ajax({
type: "GET",
url: "populateData.htm",
dataType:"json",
data:"userId=SampleUser",
success:function(response){
if (response.redirect) {
window.location.href = response.redirect;
}
else {
// Process the expected results...
}
},
error: function(xhr, textStatus, errorThrown) {
alert('Error! Status = ' + xhr.status);
}
});
});
You could also add a Header Variable to your response and let your browser decide where to redirect. In Java, instead of redirecting, do response.setHeader("REQUIRES_AUTH", "1")
and in JQuery you do on success(!):
//....
success:function(response){
if (response.getResponseHeader('REQUIRES_AUTH') === '1'){
window.location.href = 'login.htm';
}
else {
// Process the expected results...
}
}
//....
Hope that helps.
My answer is heavily inspired by this thread which shouldn't left any questions in case you still have some problems.
If using @worldofjr answer in jQuery you are getting error:
e.relatedTarget.data is not a function
you should use:
$('#myModal').on('show.bs.modal', function (e) {
var loadurl = $(e.relatedTarget).data('load-url');
$(this).find('.modal-body').load(loadurl);
});
Not that e.relatedTarget
if wrapped by $(..)
I was getting the error in latest Bootstrap 3 and after using this method it's working without any problem.
To avoid the error
Cannot find class in classpath: (name of testcase file)
you need to hold Runner class and Test class in one place. I mean src and test folders.
When I worked on Mac OS X in the lab I was able to get the terminal colors from using Terminal (rather than X11) and then editing the profile (from the Mac menu bar). The interface is a bit odd on the colors, but you have to set the modified theme as default.
Further settings worked by editing .bashrc
.
For use in command line:
for /f "tokens=5" %a in ('netstat -aon ^| find ":8080" ^| find "LISTENING"') do taskkill /f /pid %a
For use in bat-file:
for /f "tokens=5" %%a in ('netstat -aon ^| find ":8080" ^| find "LISTENING"') do taskkill /f /pid %%a
let indexPathRow:Int = 0
let indexPosition = IndexPath(row: indexPathRow, section: 0)
tableView.reloadRows(at: [indexPosition], with: .none)
Most easy and clean solution to avoid this is adding onclick="return false;"
to a
tag.
<ul class="nav nav-tabs">
<li class="active">
<a href="#home" onclick="return false;">Home</a>
</li>
<li>
<a href="#ApprovalDetails" onclick="return false;">Approval Details</a>
</li>
</ul>
"cursor:no-drop;"
just makes cursor look disabled, but is clickable, Url gets appending with href target for ex page.apsx#Home
"disabled"
class to <li>
AND removing href

Facebook uses what's called the Open Graph Protocol to decide what things to display when you share a link. The OGP looks at your page and tries to decide what content to show. We can lend a hand and actually tell Facebook what to take from our page.
The way we do that is with og:meta
tags.
The tags look something like this -
<meta property="og:title" content="Stuffed Cookies" />
<meta property="og:image" content="http://fbwerks.com:8000/zhen/cookie.jpg" />
<meta property="og:description" content="The Turducken of Cookies" />
<meta property="og:url" content="http://fbwerks.com:8000/zhen/cookie.html">
You'll need to place these or similar meta tags in the <head>
of your HTML file. Don't forget to substitute the values for your own!
For more information you can read all about how Facebook uses these meta tags in their documentation. Here is one of the tutorials from there - https://developers.facebook.com/docs/opengraph/tutorial/
Facebook gives us a great little tool to help us when dealing with these meta tags - you can use the Debugger to see how Facebook sees your URL, and it'll even tell you if there are problems with it.
One thing to note here is that every time you make a change to the meta tags, you'll need to feed the URL through the Debugger again so that Facebook will clear all the data that is cached on their servers about your URL.
Try this:
$('#dropDownId option').filter(':selected').text();
$('#dropDownId option').filter(':selected').val();

You need to update MVC.
Here's a simple method:
public static boolean checkDatePattern(String padrao, String data) {
try {
SimpleDateFormat format = new SimpleDateFormat(padrao, LocaleUtils.DEFAULT_LOCALE);
format.parse(data);
return true;
} catch (ParseException e) {
return false;
}
}
Or you can do the same using sql query:
Click on SQL present along side Structure
TRUNCATE tablename; //offers better performance, but used only when all entries need to be cleared
or
DELETE FROM tablename; //returns the number of rows deleted
for Mac OS just go to applications and just run these Scripts Install Certificates.command and Update Shell Profile.command, now it will work.
JS does not have a sleep function, it has setTimeout() or setInterval() functions.
If you can move the code that you need to run after the pause into the setTimeout()
callback, you can do something like this:
//code before the pause
setTimeout(function(){
//do what you need here
}, 2000);
see example here : http://jsfiddle.net/9LZQp/
This won't halt the execution of your script, but due to the fact that setTimeout()
is an asynchronous function, this code
console.log("HELLO");
setTimeout(function(){
console.log("THIS IS");
}, 2000);
console.log("DOG");
will print this in the console:
HELLO
DOG
THIS IS
(note that DOG is printed before THIS IS)
You can use the following code to simulate a sleep for short periods of time:
function sleep(milliseconds) {
var start = new Date().getTime();
for (var i = 0; i < 1e7; i++) {
if ((new Date().getTime() - start) > milliseconds){
break;
}
}
}
now, if you want to sleep for 1 second, just use:
sleep(1000);
example: http://jsfiddle.net/HrJku/1/
please note that this code will keep your script busy for n milliseconds. This will not only stop execution of Javascript on your page, but depending on the browser implementation, may possibly make the page completely unresponsive, and possibly make the entire browser unresponsive. In other words this is almost always the wrong thing to do.
The error:
'int' object has no attribute '__getitem__'
means that you're attempting to apply the index operator []
on an int, not a list. So is col
not a list, even when it should be? Let's start from that.
Look here:
col = [[0 for col in range(5)] for row in range(6)]
Use a different variable name inside, looks like the list comprehension overwrites the col
variable during iteration. (Not during the iteration when you set col
, but during the following ones.)
I don't have enough rep to put this under comments to the existing answers:
unescape
is only deprecated for working with URIs (or any encoded utf-8) which is probably the case for most people's needs. encodeURIComponent
converts a js string to escaped UTF-8 and decodeURIComponent
only works on escaped UTF-8 bytes. It throws an error for something like decodeURIComponent('%a9'); // error
because extended ascii isn't valid utf-8 (even though that's still a unicode value), whereas unescape('%a9'); // ©
So you need to know your data when using decodeURIComponent.
decodeURIComponent won't work on "%C2"
or any lone byte over 0x7f
because in utf-8 that indicates part of a surrogate. However decodeURIComponent("%C2%A9") //gives you ©
Unescape wouldn't work properly on that // ©
AND it wouldn't throw an error, so unescape can lead to buggy code if you don't know your data.
git rebase the-branch-to-be-merged
I solved the problem using this git command, but rebase
is only suited for some cases.
just write which python
in your terminal and you will see the python path you are using.
You can use:
f.Controls[name];
Where f
is your form variable. That gives you the control with name name
.
You may have moved on by now, but... as far as I know there's no way to delete a history entry (or state).
One option I've been looking into is to handle the history yourself in JavaScript and use the window.history
object as a carrier of sorts.
Basically, when the page first loads you create your custom history object (we'll go with an array here, but use whatever makes sense for your situation), then do your initial pushState
. I would pass your custom history object as the state object, as it may come in handy if you also need to handle users navigating away from your app and coming back later.
var myHistory = [];
function pageLoad() {
window.history.pushState(myHistory, "<name>", "<url>");
//Load page data.
}
Now when you navigate, you add to your own history object (or don't - the history is now in your hands!) and use replaceState
to keep the browser out of the loop.
function nav_to_details() {
myHistory.push("page_im_on_now");
window.history.replaceState(myHistory, "<name>", "<url>");
//Load page data.
}
When the user navigates backwards, they'll be hitting your "base" state (your state object will be null) and you can handle the navigation according to your custom history object. Afterward, you do another pushState.
function on_popState() {
// Note that some browsers fire popState on initial load,
// so you should check your state object and handle things accordingly.
// (I did not do that in these examples!)
if (myHistory.length > 0) {
var pg = myHistory.pop();
window.history.pushState(myHistory, "<name>", "<url>");
//Load page data for "pg".
} else {
//No "history" - let them exit or keep them in the app.
}
}
The user will never be able to navigate forward using their browser buttons because they are always on the newest page.
From the browser's perspective, every time they go "back", they've immediately pushed forward again.
From the user's perspective, they're able to navigate backwards through the pages but not forward (basically simulating the smartphone "page stack" model).
From the developer's perspective, you now have a high level of control over how the user navigates through your application, while still allowing them to use the familiar navigation buttons on their browser. You can add/remove items from anywhere in the history chain as you please. If you use objects in your history array, you can track extra information about the pages as well (like field contents and whatnot).
If you need to handle user-initiated navigation (like the user changing the URL in a hash-based navigation scheme), then you might use a slightly different approach like...
var myHistory = [];
function pageLoad() {
// When the user first hits your page...
// Check the state to see what's going on.
if (window.history.state === null) {
// If the state is null, this is a NEW navigation,
// the user has navigated to your page directly (not using back/forward).
// First we establish a "back" page to catch backward navigation.
window.history.replaceState(
{ isBackPage: true },
"<back>",
"<back>"
);
// Then push an "app" page on top of that - this is where the user will sit.
// (As browsers vary, it might be safer to put this in a short setTimeout).
window.history.pushState(
{ isBackPage: false },
"<name>",
"<url>"
);
// We also need to start our history tracking.
myHistory.push("<whatever>");
return;
}
// If the state is NOT null, then the user is returning to our app via history navigation.
// (Load up the page based on the last entry of myHistory here)
if (window.history.state.isBackPage) {
// If the user came into our app via the back page,
// you can either push them forward one more step or just use pushState as above.
window.history.go(1);
// or window.history.pushState({ isBackPage: false }, "<name>", "<url>");
}
setTimeout(function() {
// Add our popstate event listener - doing it here should remove
// the issue of dealing with the browser firing it on initial page load.
window.addEventListener("popstate", on_popstate);
}, 100);
}
function on_popstate(e) {
if (e.state === null) {
// If there's no state at all, then the user must have navigated to a new hash.
// <Look at what they've done, maybe by reading the hash from the URL>
// <Change/load the new page and push it onto the myHistory stack>
// <Alternatively, ignore their navigation attempt by NOT loading anything new or adding to myHistory>
// Undo what they've done (as far as navigation) by kicking them backwards to the "app" page
window.history.go(-1);
// Optionally, you can throw another replaceState in here, e.g. if you want to change the visible URL.
// This would also prevent them from using the "forward" button to return to the new hash.
window.history.replaceState(
{ isBackPage: false },
"<new name>",
"<new url>"
);
} else {
if (e.state.isBackPage) {
// If there is state and it's the 'back' page...
if (myHistory.length > 0) {
// Pull/load the page from our custom history...
var pg = myHistory.pop();
// <load/render/whatever>
// And push them to our "app" page again
window.history.pushState(
{ isBackPage: false },
"<name>",
"<url>"
);
} else {
// No more history - let them exit or keep them in the app.
}
}
// Implied 'else' here - if there is state and it's NOT the 'back' page
// then we can ignore it since we're already on the page we want.
// (This is the case when we push the user back with window.history.go(-1) above)
}
}
I added borderBottomWidth: 0 and it worked fine for me in android.
Sure. Here's a completely silly program that demonstrates calling main
recursively.
public class main
{
public static void main(String[] args)
{
for (int i = 0; i < args.length; ++i)
{
if (args[i] != "")
{
args[i] = "";
System.out.println((args.length - i) + " left");
main(args);
}
}
}
}
If you want to pass parameters like user names, product names, ... etc. you can use open source template engine NVelocity to produce your final email / HTML's.
An example of NVelocity template (MailTemplate.vm) :
A sample email template by <b>$name</b>.
<br />
Foreach example :
<br />
#foreach ($item in $itemList)
[Date: $item.Date] Name: $item.Name, Value: $itemValue.Value
<br /><br />
#end
Generating mail body by MailTemplate.vm in your application :
VelocityContext context = new VelocityContext();
context.Put("name", "ScarletGarden");
context.Put("itemList", itemList);
StringWriter writer = new StringWriter();
Velocity.MergeTemplate("MailTemplate.vm", context, writer);
string mailBody = writer.GetStringBuilder().ToString();
The result mail body is :
A sample email template by ScarletGarden.
Foreach example :
[Date: 12.02.2009] Name: Item 1, Value: 09
[Date: 21.02.2009] Name: Item 4, Value: 52
[Date: 01.03.2009] Name: Item 2, Value: 21
[Date: 23.03.2009] Name: Item 6, Value: 24
For editing the templates, maybe you can use FCKEditor and save your templates to files.
This example selects a new Range
of Cells
defined by the current cell to a cell 5 to the right.
Note that .Offset
takes arguments of Offset(row, columns)
and can be quite useful.
Sub testForStackOverflow()
Range(ActiveCell, ActiveCell.Offset(0, 5)).Copy
End Sub
if you don't want add the attr disabled can do it programmatically
can disable the edition into the <select class="yourClass">
element with this code:
//bloqueo selects
//block all selects
jQuery(document).on("focusin", 'select.yourClass', function (event) {
var $selectDiabled = jQuery(this).attr('disabled', 'disabled');
setTimeout(function(){ $selectDiabled.removeAttr("disabled"); }, 30);
});
if you want try it can see it here: https://jsfiddle.net/9kjqjLyq/
Here is a basic hover example.
Component's template property:
Template
<!-- attention, we have the c_highlight class -->
<!-- c_highlight is the selector property value of the directive -->
<p class="c_highlight">
Some text.
</p>
And our directive
import {Component,HostListener,Directive,HostBinding} from '@angular/core';
@Directive({
// this directive will work only if the DOM el has the c_highlight class
selector: '.c_highlight'
})
export class HostDirective {
// we could pass lots of thing to the HostBinding function.
// like class.valid or attr.required etc.
@HostBinding('style.backgroundColor') c_colorrr = "red";
@HostListener('mouseenter') c_onEnterrr() {
this.c_colorrr= "blue" ;
}
@HostListener('mouseleave') c_onLeaveee() {
this.c_colorrr = "yellow" ;
}
}
There is a generic solution:
Lets say you have a controller named Admin where you put content for authorized users.
Then, you can override the Initialize
or OnAuthorization
methods of Admin controller and write redirect to login page logic on session timeout in these methods as described:
protected override void OnAuthorization(System.Web.Mvc.AuthorizationContext filterContext)
{
//lets say you set session value to a positive integer
AdminLoginType = Convert.ToInt32(filterContext.HttpContext.Session["AdminLoginType"]);
if (AdminLoginType == 0)
{
filterContext.HttpContext.Response.Redirect("~/login");
}
base.OnAuthorization(filterContext);
}

Java usually doesn't like accessing hardware, so you will need a driver program of some sort, as goldenmean said. I've done this on my laptop by finding a command line program that snaps a picture. Then it's the same as goldenmean explained; you run the command line program from your java program in the takepicture() routine, and the rest of your code runs the same.
Except for the part about reading pixel values into an array, you might be better served by saving the file to BMP, which is nearly that format already, then using the standard java image libraries on it.
Using a command line program adds a dependency to your program and makes it less portable, but so was the webcam, right?
In cell A1, enter the time.
In cell B2, enter =A1+1/24
It will be written on a new line if you examine the source code of the page. If you want it to appear on a new line when it is rendered in the browser, you'll have use a <br />
tag instead.

(create it if necessary).

Probably the file is not in the path specified. '../../../' will move 3 step up to the directory in which the page is located and look for the js file in a folder named JS.

In the case you need to manually 'exit' a transaction through code (be it through an exception or simply checking an error state) you shouldn't use DB::transaction()
but instead wrap your code in DB::beginTransaction
and DB::commit
/DB::rollback()
:
DB::beginTransaction();
try {
DB::insert(...);
DB::insert(...);
DB::insert(...);
DB::commit();
// all good
} catch (\Exception $e) {
DB::rollback();
// something went wrong
}
See the transaction docs.
Use the traceback module:
import sys
import traceback
try:
assert True
assert 7 == 7
assert 1 == 2
# many more statements like this
except AssertionError:
_, _, tb = sys.exc_info()
traceback.print_tb(tb) # Fixed format
tb_info = traceback.extract_tb(tb)
filename, line, func, text = tb_info[-1]
print('An error occurred on line {} in statement {}'.format(line, text))
exit(1)
The easiest solution is to use
Just as @Wessie noted, dict.iteritems
, dict.iterkeys
and dict.itervalues
(which return an iterator in Python2.x) as well as dict.viewitems
, dict.viewkeys
and dict.viewvalues
(which return view objects in Python2.x) were all removed in Python3.x
And dict.items
, dict.keys
and dict.values
used to return a copy of the dictionary's list in Python2.x now return view objects in Python3.x, but they are still not the same as iterator.
If you want to return an iterator in Python3.x, use iter(dictview)
:
$ python3.3
>>> d = {'one':'1', 'two':'2'}
>>> type(d.items())
<class 'dict_items'>
>>>
>>> type(d.keys())
<class 'dict_keys'>
>>>
>>>
>>> ii = iter(d.items())
>>> type(ii)
<class 'dict_itemiterator'>
>>>
>>> ik = iter(d.keys())
>>> type(ik)
<class 'dict_keyiterator'>
From the help page on searching code, it seems that this isn't yet possible.
You can search for text in your repository, including the ability to choose files or paths to search in, but you can't specify that you want to search in commits.
Maybe suggest this to them?
My solution. The JSONServer is a class I wrote for running an HttpListener server in a console window.
class Program
{
public static JSONServer srv = null;
static void Main(string[] args)
{
Console.WriteLine("NLPS Core Server");
srv = new JSONServer(100);
srv.Start();
InputLoopProcessor();
while(srv.IsRunning)
{
Thread.Sleep(250);
}
}
private static async Task InputLoopProcessor()
{
string line = "";
Console.WriteLine("Core NLPS Server: Started on port 8080. " + DateTime.Now);
while(line != "quit")
{
Console.Write(": ");
line = Console.ReadLine().ToLower();
Console.WriteLine(line);
if(line == "?" || line == "help")
{
Console.WriteLine("Core NLPS Server Help");
Console.WriteLine(" ? or help: Show this help.");
Console.WriteLine(" quit: Stop the server.");
}
}
srv.Stop();
Console.WriteLine("Core Processor done at " + DateTime.Now);
}
}
You mean InputBox? Just look in the Microsoft.VisualBasic namespace.
C# and VB.Net share a common library. If one language can use it, so can the other.
