In your invoke web request just use the parameter -UseBasicParsing
e.g. in your script (line 2) you should use:
$rss = Invoke-WebRequest -Uri $url -UseBasicParsing
According to the documentation, this parameter is necessary on systems where IE isn't installed or configured:
Uses the response object for HTML content without Document Object Model (DOM) parsing. This parameter is required when Internet Explorer is not installed on the computers, such as on a Server Core installation of a Windows Server operating system.

The problem, as you've spotted, is that String.Contains
does not perform a word-boundary check, so Contains("float")
will return true
for both "foo float bar" (correct) and "unfloating" (which is incorrect).
The solution is to ensure that "float" (or whatever your desired class-name is) appears alongside a word-boundary at both ends. A word-boundary is either the start (or end) of a string (or line), whitespace, certain punctuation, etc. In most regular-expressions this is \b
. So the regex you want is simply: \bfloat\b
.
A downside to using a Regex
instance is that they can be slow to run if you don't use the .Compiled
option - and they can be slow to compile. So you should cache the regex instance. This is more difficult if the class-name you're looking for changes at runtime.
Alternatively you can search a string for words by word-boundaries without using a regex by implementing the regex as a C# string-processing function, being careful not to cause any new string or other object allocation (e.g. not using String.Split
).
Suppose you just want to look for elements with a single, design-time specified class-name:
class Program {
private static readonly Regex _classNameRegex = new Regex( @"\bfloat\b", RegexOptions.Compiled );
private static IEnumerable<HtmlNode> GetFloatElements(HtmlDocument doc) {
return doc
.Descendants()
.Where( n => n.NodeType == NodeType.Element )
.Where( e => e.Name == "div" && _classNameRegex.IsMatch( e.GetAttributeValue("class", "") ) );
}
}
If you need to choose a single class-name at runtime then you can build a regex:
private static IEnumerable<HtmlNode> GetElementsWithClass(HtmlDocument doc, String className) {
Regex regex = new Regex( "\\b" + Regex.Escape( className ) + "\\b", RegexOptions.Compiled );
return doc
.Descendants()
.Where( n => n.NodeType == NodeType.Element )
.Where( e => e.Name == "div" && regex.IsMatch( e.GetAttributeValue("class", "") ) );
}
If you have multiple class-names and you want to match all of them, you could create an array of Regex
objects and ensure they're all matching, or combine them into a single Regex
using lookarounds, but this results in horrendously complicated expressions - so using a Regex[]
is probably better:
using System.Linq;
private static IEnumerable<HtmlNode> GetElementsWithClass(HtmlDocument doc, String[] classNames) {
Regex[] exprs = new Regex[ classNames.Length ];
for( Int32 i = 0; i < exprs.Length; i++ ) {
exprs[i] = new Regex( "\\b" + Regex.Escape( classNames[i] ) + "\\b", RegexOptions.Compiled );
}
return doc
.Descendants()
.Where( n => n.NodeType == NodeType.Element )
.Where( e =>
e.Name == "div" &&
exprs.All( r =>
r.IsMatch( e.GetAttributeValue("class", "") )
)
);
}
The advantage of using a custom C# method to do string matching instead of a regex is hypothetically faster performance and reduced memory usage (though Regex
may be faster in some circumstances - always profile your code first, kids!)
This method below: CheapClassListContains
provides a fast word-boundary-checking string matching function that can be used the same way as regex.IsMatch
:
private static IEnumerable<HtmlNode> GetElementsWithClass(HtmlDocument doc, String className) {
return doc
.Descendants()
.Where( n => n.NodeType == NodeType.Element )
.Where( e =>
e.Name == "div" &&
CheapClassListContains(
e.GetAttributeValue("class", ""),
className,
StringComparison.Ordinal
)
);
}
/// <summary>Performs optionally-whitespace-padded string search without new string allocations.</summary>
/// <remarks>A regex might also work, but constructing a new regex every time this method is called would be expensive.</remarks>
private static Boolean CheapClassListContains(String haystack, String needle, StringComparison comparison)
{
if( String.Equals( haystack, needle, comparison ) ) return true;
Int32 idx = 0;
while( idx + needle.Length <= haystack.Length )
{
idx = haystack.IndexOf( needle, idx, comparison );
if( idx == -1 ) return false;
Int32 end = idx + needle.Length;
// Needle must be enclosed in whitespace or be at the start/end of string
Boolean validStart = idx == 0 || Char.IsWhiteSpace( haystack[idx - 1] );
Boolean validEnd = end == haystack.Length || Char.IsWhiteSpace( haystack[end] );
if( validStart && validEnd ) return true;
idx++;
}
return false;
}
HtmlAgilityPack is somewhat stagnated doesn't support .querySelector
and .querySelectorAll
, but there are third-party libraries that extend HtmlAgilityPack with it: namely Fizzler and CssSelectors. Both Fizzler and CssSelectors implement QuerySelectorAll
, so you can use it like so:
private static IEnumerable<HtmlNode> GetDivElementsWithFloatClass(HtmlDocument doc) {
return doc.QuerySelectorAll( "div.float" );
}
With runtime-defined classes:
private static IEnumerable<HtmlNode> GetDivElementsWithClasses(HtmlDocument doc, IEnumerable<String> classNames) {
String selector = "div." + String.Join( ".", classNames );
return doc.QuerySelectorAll( selector );
}
Just like you do for getting something from the CNode
you also need to do for the ANode
XmlNodeList xnList = xml.SelectNodes("/Element[@*]");
foreach (XmlNode xn in xnList)
{
XmlNode anode = xn.SelectSingleNode("ANode");
if (anode!= null)
{
string id = anode["ID"].InnerText;
string date = anode["Date"].InnerText;
XmlNodeList CNodes = xn.SelectNodes("ANode/BNode/CNode");
foreach (XmlNode node in CNodes)
{
XmlNode example = node.SelectSingleNode("Example");
if (example != null)
{
string na = example["Name"].InnerText;
string no = example["NO"].InnerText;
}
}
}
}
For integer types, you can do
a ^= b;
b ^= a;
a ^= b;
using the bit-wise xor operator ^
. As all the other suggestions, you probably shouldn't use it in production code.
For a reason I don't know, the single line version a ^= b ^= a ^= b
doesn't work (maybe my Java compiler has a bug). The single line worked in C with all compilers I tried. However, two-line versions work:
a ^= b ^= a;
b ^= a;
as well as
b ^= a;
a ^= b ^= a;
A proof that it works: Let a0 and b0 be the initial values for a
and b
. After the first line, a
is a1 = a0 xor b0; after the second line, b
is b1 = b0 xor a1 = b0 xor (a0 xor b0) = a0. After the third line, a
is a2 = a1 xor b1 = a1 xor (b0 xor a1) = b0.
Locations are evaluated in this order:
location = /path/file.ext {}
Exact matchlocation ^~ /path/ {}
Priority prefix match -> longest firstlocation ~ /Paths?/ {}
(case-sensitive regexp) and location ~* /paths?/ {}
(case-insensitive regexp) -> first matchlocation /path/ {}
Prefix match -> longest firstThe priority prefix match (number 2) is exactly as the common prefix match (number 4), but has priority over any regexp.
For both prefix matche types the longest match wins.
Case-sensitive and case-insensitive have the same priority. Evaluation stops at the first matching rule.
Documentation says that all prefix rules are evaluated before any regexp, but if one regexp matches then no standard prefix rule is used. That's a little bit confusing and does not change anything for the priority order reported above.
That watermark in the bottom right only appears on mouseover
. There's no parameter to remove that, however if you stack a transparent div
on top of the video and make it a higher z-index
and the same size of the video, your mouseover
will not trigger the watermark because your mouse will be hitting the div
.
Of course the tradeoff for this is that you lose the ability to actually click on the video to pause it. But if you want to leave the ability to pause it, you could display the controls and have the top layer div
cover up until the bottom 30 pixels or so, letting you click the controls.
Use for a date three days ago:
WHERE t.date >= DATE_ADD(CURDATE(), INTERVAL -3 DAY);
Check the DATE_ADD documentation.
Or you can use:
WHERE t.date >= ( CURDATE() - INTERVAL 3 DAY )
Run cmd
and then run node server.js
. In your example, you are trying to use the REPL to run your command, which is not going to work. The ellipsis is node.js expecting more tokens before closing the current scope (you can type code in and run it on the fly here)

Be sure there is nothing on your button (such a div or a trasparent img) that keeps from clicking the button. It sounds stupid, but sometimes we think that jQuery is not working and all that stuffs and the problem is on the positioning of DOM elements.

Permission denied
In order to run a script the file must have an executable permission bit set.
In order to fully understand Linux file permissions you can study the documentation for the chmod
command. chmod, an abbreviation of change mode, is the command that is used to change the permission settings of a file.
To read the chmod documentation for your local system , run man chmod
or info chmod
from the command line. Once read and understood you should be able to understand the output of running ...
ls -l foo.sh
... which will list the READ, WRITE and EXECUTE permissions for the file owner, the group owner and everyone else who is not the file owner or a member of the group to which the file belongs (that last permission group is sometimes referred to as "world" or "other")
Here's a summary of how to troubleshoot the Permission Denied error in your case.
$ ls -l foo.sh # Check file permissions of foo
-rw-r--r-- 1 rkielty users 0 2012-10-21 14:47 foo.sh
^^^
^^^ | ^^^ ^^^^^^^ ^^^^^
| | | | |
Owner| World | |
| | Name of
Group | Group
Name of
Owner
Owner has read and write access rw but the - indicates that the executable permission is missing
The chmod
command fixes that. (Group and other only have read permission set on the file, they cannot write to it or execute it)
$ chmod +x foo.sh # The owner can set the executable permission on foo.sh
$ ls -l foo.sh # Now we see an x after the rw
-rwxr-xr-x 1 rkielty users 0 2012-10-21 14:47 foo.sh
^ ^ ^
foo.sh is now executable as far as Linux is concerned.
Using sudo results in Command not found
When you run a command using sudo you are effectively running it as the superuser or root.
The reason that the root user is not finding your command is likely that the PATH
environment variable for root does not include the directory where foo.sh
is located. Hence the command is not found.
The PATH environment variable contains a list of directories which are searched for commands. Each user sets their own PATH variable according to their needs. To see what it is set to run
env | grep ^PATH
Here's some sample output of running the above env
command first as an ordinary user and then as the root user using sudo
rkielty@rkielty-laptop:~$ env | grep ^PATH
PATH=/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games
rkielty@rkielty-laptop:~$ sudo env | grep ^PATH
[sudo] password for rkielty:
PATH=/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/X11R6/bin
Note that, although similar, in this case the directories contained in the PATH the non-privileged user (rkielty) and the super user are not the same.
The directory where foo.sh
resides is not present in the PATH variable of the root user, hence the command not found error.
I wanted to do something similar, but on a form with a background image, I found that when the text in the label changed the repaints were obvious with this method, so I did the following: * Set the label AutoSize to true and TextAlign to MiddleCenter
Then, each time the text changed (mine was done using a timer) I called the following method:
private Point GetPosition()
{
int y = (this.Height / 2) - (label1.Height / 2);
int x = (this.Width / 2) - (label1.Width / 2);
return new Point(x, y);
}
And set the label's Location property to this return value. This ensured that the label was always in the center of the form when the text changed and the repaints for a full-screen form weren't obvious.
ContactNumbers = new List<ContactNumber>();
If you want it to be passed in, just take
public Human(List<ContactNumber> numbers)
{
ContactNumbers = numbers;
}
Something you may want to investigate, at least for windows, is the AllocConsole() function in the windows api. It calls GetStdHandle a few times to redirect stdout, stderr, etc. (A quick test shows this doesn't entirely do what we want it to do. You do get a console window opened alongside your other Qt stuff, but you can't output to it. Presumably, because the console window is open, there is some way to access it, get a handle to it, or access and manipulate it somehow. Here's the MSDN documentation for those interested in figuring this out:
AllocConsole(): http://msdn.microsoft.com/en-us/library/windows/desktop/ms681944%28v=vs.85%29.aspx
GetStdHandle(...): http://msdn.microsoft.com/en-us/library/windows/desktop/ms683231%28v=vs.85%29.aspx
(I'd add this as a comment, but the rules prevent me from doing so...)
Simply place this on a new line in .gitignore
**/.DS_Store
From git documentation
- A leading "**" followed by a slash means match in all directories. For example, "**/foo" matches file or directory "foo" anywhere, the same as pattern "foo". "**/foo/bar" matches file or directory "bar" anywhere that is directly under directory "foo".
As Jakub Vrána (The creator or Adminer and NotORM) mentions in the comments, to select the current timezone offset in TIME
use:
SELECT TIMEDIFF(NOW(), UTC_TIMESTAMP);
It will return: 02:00:00
if your timezone is +2:00 for that date
I made a cheatsheet here: Should MySQL have its timezone set to UTC?
The other answer is correct, but for completeness, here are other ways:

According to WWDC2015 Distribution Whats New
Setting "ITSAppUsesNonExemptEncryption" to "NO" in info.plist works fine. if no cryptographic content in your app.
I had got this pop up During selecting build for internal testing i didn't included "ITSAppUsesNonExemptEncryption" key in my info.plist but still worked for me.
Even i successfully uploaded new application didn't included "ITSEncryptionExportComplianceCode" and "ITSAppUsesNonExemptEncryption" keys.
Also Apple Doc.
Important: If your app requires that you provide additional documents for the encryption review, your app won’t have the Ready for Sale status on the store until Export Compliance has reviewed and approved your documents. The app can’t be distributed for prerelease testing until Export Compliance has reviewed and approved it.
If your app is not using encryption and you don’t want to have to answer these questions at the time of submission, you can provide export compliance information with your build. You can also provide new or updated documentation via iTunes Connect to receive the appropriate key string value to include with your build before uploading it to iTunes Connect.
To add export compliance documentation in iTunes Connect:
Go to the Encryption section under Features. Click the plus sign next to the appropriate platform section. Answer the questions appropriately. Attach the file when prompted. Click Save. Your documents will then be sent for review immediately and the status of your document will show in Compliance Review. A key value will also be generated automatically that you can include in your Info.plist file. For more information on including the key value with your build, see the Resources and Help section Trade Compliance.
You can upload a build without an export compliance key. If you include a key, it can indicate that you do not need export compliance documentation; this requires no approval. If you include a key that references a specific export compliance document, that document must be approved; it cannot be in In Review or Rejected.
You can review your answers at any time by clicking the document file name and selecting More Information. If you need to update your documentation or change any of the answers to the questions, you will need to repeat the steps above to add a new document that corresponds with your changes.
Use any of the following groupby
and agg
recipes.
# Setup
df = pd.DataFrame({
'a': ['A', 'A', 'B', 'B', 'B', 'C'],
'b': [1, 2, 5, 5, 4, 6],
'c': ['x', 'y', 'z', 'x', 'y', 'z']
})
df
a b c
0 A 1 x
1 A 2 y
2 B 5 z
3 B 5 x
4 B 4 y
5 C 6 z
To aggregate multiple columns as lists, use any of the following:
df.groupby('a').agg(list)
df.groupby('a').agg(pd.Series.tolist)
b c
a
A [1, 2] [x, y]
B [5, 5, 4] [z, x, y]
C [6] [z]
To group-listify a single column only, convert the groupby to a SeriesGroupBy
object, then call SeriesGroupBy.agg
. Use,
df.groupby('a').agg({'b': list}) # 4.42 ms
df.groupby('a')['b'].agg(list) # 2.76 ms - faster
a
A [1, 2]
B [5, 5, 4]
C [6]

Same as
class PaymentsForm(forms.ModelForm):
date = forms.DateField(widget=SelectDateWidget())
class Meta:
model = Payments
put this in your forms.py from django.forms.extras.widgets import SelectDateWidget
The difference is that ActionEvent
is fired when the action is performed on the JCheckBox
that is its state is changed either by clicking on it with the mouse or with a space bar or a mnemonic. It does not really listen to change events whether the JCheckBox
is selected or deselected.
For instance, if JCheckBox c1
(say) is added to a ButtonGroup
. Changing the state of other JCheckBoxes
in the ButtonGroup
will not fire an ActionEvent
on other JCheckBox
, instead an ItemEvent
is fired.
Final words: An ItemEvent
is fired even when the user deselects a check box by selecting another JCheckBox
(when in a ButtonGroup
), however ActionEvent
is not generated like that instead ActionEvent
only listens whether an action is performed on the JCheckBox
(to which the ActionListener
is registered only) or not. It does not know about ButtonGroup
and all other selection/deselection stuff.
that because you calling toggle inside the render method which will cause to re-render and toggle will call again and re-rendering again and so on
this line at your code
{<td><span onClick={this.toggle()}>Details</span></td>}
you need to make onClick
refer to this.toggle
not calling it
to fix the issue do this
{<td><span onClick={this.toggle}>Details</span></td>}
I don't know why it does not work for Html.EditorFor but I tried TextBoxFor and it worked for me.
@Html.TextBoxFor(m => m.Name, new { Class = "className", Size = "40"})
...and also validation works.
As Yanflea mentioned, there is a way to go around this.

I think it's perfectly explained in item 25 of Scott Meyers' Effective Modern C++. Here's an excerpt:
The part of the Standard blessing the RVO goes on to say that if the conditions for the RVO are met, but compilers choose not to perform copy elision, the object being returned must be treated as an rvalue. In effect, the Standard requires that when the RVO is permitted, either copy elision takes place or
std::move
is implicitly applied to local objects being returned.
Here, RVO refers to return value optimization, and if the conditions for the RVO are met means returning the local object declared inside the function that you would expect to do the RVO, which is also nicely explained in item 25 of his book by referring to the standard (here the local object includes the temporary objects created by the return statement). The biggest take away from the excerpt is either copy elision takes place or std::move
is implicitly applied to local objects being returned. Scott mentions in item 25 that std::move
is implicitly applied when the compiler choose not to elide the copy and the programmer should not explicitly do so.
In your case, the code is clearly a candidate for RVO as it returns the local object p
and the type of p
is the same as the return type, which results in copy elision. And if the compiler chooses not to elide the copy, for whatever reason, std::move
would've kicked in to line 1
.
For anyone seeking a solution that does not use the command line: ctrl+shift+t
Have you tried it?
If you do:
var HI = 'Hello World';
In global.js
. And then do:
alert(HI);
In js1.js
it will alert it fine. You just have to include global.js
prior to the rest in the HTML document.
The only catch is that you have to declare it in the window's scope (not inside any functions).
You could just nix the var
part and create them that way, but it's not good practice.

If we have a dynamic value that needs to go in a css background or background-image attribute, it can be just a bit more tricky to specify.
Let’s say we have a getImage() function in our controller. This function returns a string formatted similar to this: url(icons/pen.png). If we do, the ngStyle declaration is specified the exact same way as before:
ng-style="{ 'background-image': getImage() }"
Make sure to put quotes around the background-image key name. Remember, this must be formatted as a valid Javascript object key.

One solution to this is to do what msysGit's rebasing merge script does - after the rebase, merge in the old head of feature
with -s ours
. You end up with the commit graph:
A--B--C------F--G (master)
\ \
\ D'--E' (feature)
\ /
\ --
\ /
D--E (old-feature)
... and your push of feature
will be a fast-forward.
In other words, you can do:
git checkout feature
git branch old-feature
git rebase master
git merge -s ours old-feature
git push origin feature
(Not tested, but I think that's right...)
In SQL Server 2008 in addition to the above two options you have a third option to make this setting through SQL Server Management Studio.
1.Start Management Studio and connect to Report Server Instance (make sure you select 'Reporting Services' server type).
2.Right click on the ReportServer and Select Properties
3.Click Advanced
4.In EnableRemoteErrors, select True.
5.Click OK.
The Gutenberg Project hosts Webster's Unabridged English Dictionary plus many other public domain literary works. Actually it looks like they've got several versions of the dictionary hosted with copyright from different years. The one I linked has a 2009 copyright. You may want to poke around the site and investigate the different versions of Webster's dictionary.
You just need to make sure you have the rights to push to the remote repository and do
git push origin master
or simply
git push

Run php --ini
and notice file path on Loaded Configuration File
.
Then run command like cat -n /etc/php/7.2/cli/php.ini | grep intl
to find if the extension is commented or not.
Then update loaded configuration file by commenting line by adding ;
such as ;extension=intl
This can happen when you install php-intl
package and also enable the same extension on php.ini
file.
For me it was the "Single Sign On" (can be seen at the bottome of the screenshot in phwd's answer) setting that was turned off.
This is a metadata change only: it is quick.
An observation: specify NULL or NOT NULL explicitly to avoid "accidents" if one of the SET ANSI_xx settings are different eg run in osql not SSMS for some reason
Sometimes it can be tricky to use raw html. Mostly because of XSS vulnerability. If that is a concern, but you still want to use raw html, you can encode the scary parts.
@Html.Raw("(<b>" + Html.Encode("<script>console.log('insert')</script>" + "Hello") + "</b>)")
Results in
(<b><script>console.log('insert')</script>Hello</b>)
Use this if the session variable emp_num will store a string:
if (!string.IsNullOrEmpty(Session["emp_num"] as string))
{
//The code
}
If it doesn't store a string, but some other type, you should just check for null before accessing the value, as in your second example.
http://docs.jquery.com/Plugins/Validation/CustomMethods/phoneUS
Check that out. It should be just what you're looking for. A US phone validation plugin for jQuery.
If you want to do it on your own, you're going to be in for a good amount of work. Check out the isNaN()
function. It tells you if it is not a number. You're also going to want to brush up on your regular expressions for validation. If you're using RegEx, you can go without isNaN()
, as you'll be testing for that anyway.
Option 1 (via controller):
angular.controller('numCtrl', function($scope, $window) {
$scope.num = parseInt(num , 10);
}
Option 2 (via custom filter):
app.filter('num', function() {
return function(input) {
return parseInt(input, 10);
}
});
{{(num1 | num) + (num2 | num)}}
Option 3 (via expression):
Declare this first in your controller:
$scope.parseInt = parseInt;
Then:
{{parseInt(num1)+parseInt(num2)}}
Option 4 (from raina77ow)
{{(num1-0) + (num2-0)}}
If Apache was installed using NSIS installer it should have left an uninstaller. You should search inside Apache installation directory for executable named unistaller.exe
or something like that. NSIS uninstallers support /S
flag by default for silent uninstall. So you can run something like "C:\Program Files\<Apache installation dir here>\uninstaller.exe" /S
From NSIS documentation:
3.2.1 Common Options
/NCRC disables the CRC check, unless CRCCheck force was used in the script. /S runs the installer or uninstaller silently. See section 4.12 for more information. /D sets the default installation directory ($INSTDIR), overriding InstallDir and InstallDirRegKey. It must be the last parameter used in the command line and must not contain any quotes, even if the path contains spaces. Only absolute paths are supported.
Here is some modifications of the above Ryan Artecona's solution.
function myGetPxStyle(e,p)
{
var r=window.getComputedStyle?window.getComputedStyle(e,null)[p]:"";
return parseFloat(r);
}
function myGetClick=function(ev)
{
// {x:ev.layerX,y:ev.layerY} doesn't work when zooming with mac chrome 27
// {x:ev.clientX,y:ev.clientY} not supported by mac firefox 21
// document.body.scrollLeft and document.body.scrollTop seem required when scrolling on iPad
// html is not an offsetParent of body but can have non null offsetX or offsetY (case of wordpress 3.5.1 admin pages for instance)
// html.offsetX and html.offsetY don't work with mac firefox 21
var offsetX=0,offsetY=0,e=this,x,y;
var htmls=document.getElementsByTagName("html"),html=(htmls?htmls[0]:0);
do
{
offsetX+=e.offsetLeft-e.scrollLeft;
offsetY+=e.offsetTop-e.scrollTop;
} while (e=e.offsetParent);
if (html)
{
offsetX+=myGetPxStyle(html,"marginLeft");
offsetY+=myGetPxStyle(html,"marginTop");
}
x=ev.pageX-offsetX-document.body.scrollLeft;
y=ev.pageY-offsetY-document.body.scrollTop;
return {x:x,y:y};
}
After misunderstanding, I finally got what you are trying to do. You should check your server configuration files; are you using apache2 or some other server software?
Look for lines that start with LoadModule php
...
There probably are configuration files/directories named mods
or something like that, start from there.
You could also check output from php -r 'phpinfo();' | grep php
and compare lines to phpinfo();
from web server.
php
interactively:(so you can paste/write code in the console)
php -a
php -f file.php
php -f file.php > results.html
To run only small part, one line or like, you can use:
php -r '$x = "Hello World"; echo "$x\n";'
If you are running linux then do man php
at console.
if you need/want to run php through fpm, use cli fcgi
SCRIPT_NAME="file.php" SCRIP_FILENAME="file.php" REQUEST_METHOD="GET" cgi-fcgi -bind -connect "/var/run/php-fpm/php-fpm.sock"
where /var/run/php-fpm/php-fpm.sock is your php-fpm socket file.
Here the defination of Rendersection from MSDN
In layout pages, renders the content of a named section.MSDN
In _layout.cs page put
@RenderSection("Bottom",false)
Here render the content of bootom section and specifies false
boolean property to specify whether the section is required or not.
@section Bottom{
This message form bottom.
}
That meaning if you want to bottom section in all pages, then you must use false as the second parameter at Rendersection method.
After, or in-between your text, use the
(non-breaking space) extended HTML character.
EG 1 :
This is an example paragraph.
This is the next line.
If running Node I'd recommend:
Object.keys(obj).forEach((key, index) => {
console.log(key);
});
I had the same problem trying to connect to a remote mysql db.
I fixed it by opening the firewall on the db server to allow traffic through:
sudo ufw allow mysql
Added: I found something that should do the trick right away, but the rest of the code below also offers an alternative.
Use the subplots_adjust()
function to move the bottom of the subplot up:
fig.subplots_adjust(bottom=0.2) # <-- Change the 0.02 to work for your plot.
Then play with the offset in the legend bbox_to_anchor
part of the legend command, to get the legend box where you want it. Some combination of setting the figsize
and using the subplots_adjust(bottom=...)
should produce a quality plot for you.
Alternative: I simply changed the line:
fig = plt.figure(1)
to:
fig = plt.figure(num=1, figsize=(13, 13), dpi=80, facecolor='w', edgecolor='k')
and changed
lgd = ax.legend(loc=9, bbox_to_anchor=(0.5,0))
to
lgd = ax.legend(loc=9, bbox_to_anchor=(0.5,-0.02))
and it shows up fine on my screen (a 24-inch CRT monitor).
Here figsize=(M,N)
sets the figure window to be M inches by N inches. Just play with this until it looks right for you. Convert it to a more scalable image format and use GIMP to edit if necessary, or just crop with the LaTeX viewport
option when including graphics.
CellSpacing as the name suggests it is the Space between the Adjacent cells and CellPadding on the other hand means the padding around the cell content.
Adding the following inside "mirrors" section in the user setting.xml file worked for me.
<mirror>
<id>ibiblio.org</id>
<url>http://mirrors.ibiblio.org/maven2</url>
<mirrorOf>central</mirrorOf>
</mirror>
Continuing with JoelAnair's answer:
For more robustness, use as follows:
var el = document.getElementById('targetFrame');
if(el.contentWindow)
{
el.contentWindow.targetFunction();
}
else if(el.contentDocument)
{
el.contentDocument.targetFunction();
}
Workd like charm :)
2014 March: Truncating long strings with CSS: a new answer with focus on browser support
Demo on http://jsbin.com/leyukama/1/ (I use jsbin because it supports old version of IE).
<style type="text/css">
span {
display: inline-block;
white-space: nowrap;
overflow: hidden;
text-overflow: ellipsis; /** IE6+, Firefox 7+, Opera 11+, Chrome, Safari **/
-o-text-overflow: ellipsis; /** Opera 9 & 10 **/
width: 370px; /* note that this width will have to be smaller to see the effect */
}
</style>
<span>Some very long text that should be cut off at some point coz it's a bit too long and the text overflow ellipsis feature is used</span>
The -ms-text-overflow CSS property is not necessary: it is a synonym of the text-overflow CSS property, but versions of IE from 6 to 11 already support the text-overflow CSS property.
Successfully tested (on Browserstack.com) on Windows OS, for web browsers:
Firefox: as pointed out by Simon Lieschke (in another answer), Firefox only support the text-overflow CSS property from Firefox 7 onwards (released September 27th 2011).
I double checked this behavior on Firefox 3.0 & Firefox 6.0 (text-overflow is not supported).
Some further testing on a Mac OS web browsers would be needed.
Note: you may want to show a tooltip on mouse hover when an ellipsis is applied, this can be done via javascript, see this questions: HTML text-overflow ellipsis detection and HTML - how can I show tooltip ONLY when ellipsis is activated

Do which sshpass
in your command line to get the absolute path to sshpass
and replace it in the bash script.
You should also probably do the same with the command
you are trying to run.
The problem might be that it is not finding it.
I doubt very much a telnet library will ever be part of the .Net BCL, although you do have almost full socket support so it wouldnt be too hard to emulate a telnet client, Telnet in its general implementation is a legacy and dying technology that where exists generally sits behind a nice new modern facade. In terms of Unix/Linux variants you'll find that out the box its SSH and enabling telnet is generally considered poor practice.
You could check out: http://granados.sourceforge.net/ - SSH Library for .Net http://www.tamirgal.com/home/dev.aspx?Item=SharpSsh
You'll still need to put in place your own wrapper to handle events for feeding in input in a scripted manner.
d5d "cuts" five lines
I usually just throw the number in the middle like:
d7l = delete 7 letters
The construction is usually used in "existence" checks
if exists(select 1 from customer_table where customer = 'xxx')
or
if exists(select * from customer_table where customer = 'xxx')
Both constructions are equivalent. In the past people said the select * was better because the query governor would then use the best indexed column. This has been proven not true.
You could use loc
to get series which satisfying your condition and then iloc
to get first element:
In [2]: df
Out[2]:
A B
0 p1 1
1 p1 2
2 p3 3
3 p2 4
In [3]: df.loc[df['B'] == 3, 'A']
Out[3]:
2 p3
Name: A, dtype: object
In [4]: df.loc[df['B'] == 3, 'A'].iloc[0]
Out[4]: 'p3'
if some module you cant find, try with Static URI, for example:
var Mustache = require("/media/fabio/Datos/Express/2_required_a_module/node_modules/mustache/mustache.js");
This example, run on Ubuntu Gnome 16.04 of 64 bits, node -v: v4.2.6, npm: 3.5.2 Refer to: Blog of Ben Nadel
It will create your repository in the .git
folder in the current directory.
Use Enum.Parse()
.
var content = (ContentEnum)Enum.Parse(typeof(ContentEnum), fileContentMessage);
render() {
var myloop = [];
for (let i = 0; i < 10; i++) {
myloop.push(
<View key={i}>
<Text style={{ textAlign: 'center', marginTop: 5 }} >{i}</Text>
</View>
);
}
return (
<View >
<Text >Welcome to React Native!</Text>
{myloop}
</View>
);
}

Add following code in your onCreate() method:
Thread thread = new Thread() {
@Override
public void run() {
try {
while (!thread.isInterrupted()) {
Thread.sleep(1000);
runOnUiThread(new Runnable() {
@Override
public void run() {
// update TextView here!
}
});
}
} catch (InterruptedException e) {
}
}
};
thread.start();
This code starts an thread which sleeps 1000 milliseconds every round.
I know this a very very old and even off-topic in today's stackoverflow but I still wanted to contribute a friendly javascript answer for the simple reason that it runs in your browser.
I've also added the debugger
directive breakpoint so you can step through the code (chrome required) to see how this algorithm works. Open up your dev console in chrome (F12
in windows or CMD + OPTION + I
on mac) and then click "Run code snippet". This implements the same exact algorithm that @WhirlWind presented in his answer.
Your browser should pause execution at the debugger
directive. Use F8
to continue code execution.
function permute(rest, prefix = []) {_x000D_
if (rest.length === 0) {_x000D_
return [prefix];_x000D_
}_x000D_
return (rest_x000D_
.map((x, index) => {_x000D_
const oldRest = rest;_x000D_
const oldPrefix = prefix;_x000D_
// the `...` destructures the array into single values flattening it_x000D_
const newRest = [...rest.slice(0, index), ...rest.slice(index + 1)];_x000D_
const newPrefix = [...prefix, x];_x000D_

This method should help to programmatically generate values guaranteed to be 100% compatible with .properties
files:
public static String escapePropertyValue(final String value) {
if (value == null) {
return null;
}
try (final StringWriter writer = new StringWriter()) {
final Properties properties = new Properties();
properties.put("escaped", value);
properties.store(writer, null);
writer.flush();
final String stringifiedProperties = writer.toString();
final Pattern pattern = Pattern.compile("(.*?)escaped=(.*?)" + Pattern.quote(System.lineSeparator()) + "*");
final Matcher matcher = pattern.matcher(stringifiedProperties);
if (matcher.find() && matcher.groupCount() <= 2) {
return matcher.group(matcher.groupCount());
}
// This should never happen unless the internal implementation of Properties::store changed
throw new IllegalStateException("Could not escape property value");
} catch (final IOException ex) {
// This should never happen. IOException is only because the interface demands it
throw new IllegalStateException("Could not escape property value", ex);
}
}
You can call it like this:
final String escapedPath = escapePropertyValue("C:\\Users\\X");
writeToFile(escapedPath); // will pass "C\\:\\\\Users\\\\X"
This method a little bit expensive but, writing properties to a file is typically an sporadic operation anyway.
Simple way to solve
var day = document.getElementById("DayTextBox").value;
var regExp = /^([1-9]|[1][012])\/|-([1-9]|[1][0-9]|[2][0-9]|[3][01])\/|-([1][6-9][0-9][0-9]|[2][0][01][0-9])$/;
return regExp.test(day);
I had the same problem but finally I found the way.
Here is the walk through:
1- Install VLC on your computer (SERVER) and go to Media->Streaming (Ctrl+S)
2- Select a file to stream or if you want to stream your webcam or... click on "Capture Device" tab and do the configuration and finally click on "Stream" button.
3- Here you should do the streaming server configuration, just go to "Option" tab and paste the following command:
:sout=#transcode{vcodec=mp4v,vb=400,fps=10,width=176,height=144,acodec=mp4a,ab=32,channels=1,samplerate=22050}:rtp{sdp=rtsp://YOURCOMPUTER_SERVER_IP_ADDR:5544/}
NOTE: Replace YOURCOMPUTER_SERVER_IP_ADDR with your computer IP address or any server which is running VLC...
NOTE: You can see, the video codec is MP4V which is supported by android.
4- go to eclipse and create a new project for media playbak. create a VideoView object and in the OnCreate() function write some code like this:
mVideoView = (VideoView) findViewById(R.id.surface_view);
mVideoView.setVideoPath("rtsp://YOURCOMPUTER_SERVER_IP_ADDR:5544/");
mVideoView.setMediaController(new MediaController(this));
5- run the apk on the device (not simulator, i did not check it) and wait for the playback to be started. please consider the buffering process will take about 10 seconds...
Question: Anybody know how to reduce buffering time and play video almost live ?
contains()
method just calls equals()
on ArrayList
elements, so you can overload your class's equals()
based on the name
class variable. Return true
from equals()
if name
is equal to the matching String
. Hope this helps.
Nothing can be worse than infinity.
Here is the simplest way of achieving Light and Dark Theme for Toolbar.You have to change the value of app:theme

Building on gaoithe's answer, I attempted to make the memory units display in megabytes, and sorted by memory descending limited to 15 entries:
ps -e -orss=,args= |awk '{print $1 " " $2 }'| awk '{tot[$2]+=$1;count[$2]++} END {for (i in tot) {print tot[i],i,count[i]}}' | sort -n | tail -n 15 | sort -nr | awk '{ hr=$1/1024; printf("%13.2fM", hr); print "\t" $2 }'
588.03M /usr/sbin/apache2
275.64M /usr/sbin/mysqld
138.23M vim
97.04M -bash
40.96M ssh
34.28M tmux
17.48M /opt/digitalocean/bin/do-agent
13.42M /lib/systemd/systemd-journald
10.68M /lib/systemd/systemd
10.62M /usr/bin/redis-server
8.75M awk
7.89M sshd:
4.63M /usr/sbin/sshd
4.56M /lib/systemd/systemd-logind
4.01M /usr/sbin/rsyslogd
Here's an example alias to use it in a bash config file:
alias topmem="ps -e -orss=,args= |awk '{print \$1 \" \" \$2 }'| awk '{tot[\$2]+=\$1;count[\$2]++} END {for (i in tot) {print tot[i],i,count[i]}}' | sort -n | tail -n 15 | sort -nr | awk '{ hr=\$1/1024; printf(\"%13.2fM\", hr); print \"\t\" \$2 }'"
Then you can just type topmem
on the command line.
This would be really bad to do because sharing your connection string opens up your website to so many vulnerabilities that you can't simply patch up, you have to use a different method if you want it to be secure. Otherwise you are opening up to a huge audience to take advantage of your site.
this works for me.

# ... SSL configuration goes here
Redirect "https://www.example.com/" "http://www.example.com/"

# ...
</VirtualHost>
be sure to listen to both ports 80 and 443.
I ran into the same problem with VMWare workstation with Ubuntu guest, turns out VmWare doesn't support scrolling back up from the server view. What I did was to install x GUI, then run xterm from there. For some reason it runs the same, but lets you scroll the normal ways. Hope this helps future readers in VmWare virtual boxes.
Even better, you do not need to create separate android xml layout for list cell view. You can just use "android.R.layout.simple_list_item_1" if the list only contains textview.
private class ExampleAdapter extends ArrayAdapter<String>{
public ExampleAdapter(Context context, int textViewResourceId, String[] objects) {
super(context, textViewResourceId, objects);
}
@Override
public View getView(int position, View convertView, ViewGroup parent) {
View view = super.getView(position, convertView, parent);
TextView tv = (TextView) view.findViewById(android.R.id.text1);
tv.setTextColor(0);
return view;
}
Is the file really a symbolic link? If not, the usual test for existence is -r
or -e
.
See man test
.
Here's a solution I came up with to generate aesthetically pleasing pastel colours based on an input string. It uses the first two chars of the string as a random seed, then generates R/G/B based on that seed.
It could be easily extended so that the seed is the XOR of all chars in the string, rather than just the first two.
Inspired by David Crow's answer here: Algorithm to randomly generate an aesthetically-pleasing color palette
//magic to convert strings to a nice pastel colour based on first two chars
//
// every string with the same first two chars will generate the same pastel colour
function pastel_colour(input_str) {
//TODO: adjust base colour values below based on theme
var baseRed = 128;
var baseGreen = 128;
var baseBlue = 128;
//lazy seeded random hack to get values from 0 - 256
//for seed just take bitwise XOR of first two chars
var seed = input_str.charCodeAt(0) ^ input_str.charCodeAt(1);
var rand_1 = Math.abs((Math.sin(seed++) * 10000)) % 256;
var rand_2 = Math.abs((Math.sin(seed++) * 10000)) % 256;
var rand_3 = Math.abs((Math.sin(seed++) * 10000)) % 256;
//build colour
var red = Math.round((rand_1 + baseRed) / 2);
var green = Math.round((rand_2 + baseGreen) / 2);
var blue = Math.round((rand_3 + baseBlue) / 2);
return { red: red, green: green, blue: blue };
}

I don't understand how can datenwolf`s index generation can be correct. But still I find his solution rather clear. This is what I get after some thinking:
inline void push_indices(vector<GLushort>& indices, int sectors, int r, int s) {
int curRow = r * sectors;
int nextRow = (r+1) * sectors;
indices.push_back(curRow + s);
indices.push_back(nextRow + s);
indices.push_back(nextRow + (s+1));
indices.push_back(curRow + s);
indices.push_back(nextRow + (s+1));
indices.push_back(curRow + (s+1));
}
void createSphere(vector<vec3>& vertices, vector<GLushort>& indices, vector<vec2>& texcoords,
float radius, unsigned int rings, unsigned int sectors)
{
float const R = 1./(float)(rings-1);
float const S = 1./(float)(sectors-1);
for(int r = 0; r < rings; ++r) {
for(int s = 0; s < sectors; ++s) {
float const y = sin( -M_PI_2 + M_PI * r * R );
float const x = cos(2*M_PI * s * S) * sin( M_PI * r * R );
float const z = sin(2*M_PI * s * S) * sin( M_PI * r * R );
texcoords.push_back(vec2(s*S, r*R));
vertices.push_back(vec3(x,y,z) * radius);
push_indices(indices, sectors, r, s);
}
}
}
see if their duplicate jars or dependencies your adding remove it and your error will be gone: Eg: if you add android:supportv4 jar and also dependency you will get the error so remove the jar error will be gone
Yes it is very easy to use, but you need to load javascript file in browser by script tag
<script src="module.js"></script>
and then user in js file like
var moduel = require('./module');

Use python Sets when you need to compare hm... sets of data. Strings can be represented as sets of characters quite fast. Here I test if string is allowed phone number. First string is allowed, second not. Works fast and simple.

Never use regexps if you can avoid them.
What is this for and why would I use @":\" instead of ":\"?
Because when you have a long string with many \
you don't need to escape them all and the \n
, \r
and \f
won't work too.
For-loop in C:
for(int x = 0; x<=3; x++)
{
//Do something!
}
The same loop in 8086 assembler:
xor cx,cx ; cx-register is the counter, set to 0
loop1 nop ; Whatever you wanna do goes here, should not change cx
inc cx ; Increment
cmp cx,3 ; Compare cx to the limit
jle loop1 ; Loop while less or equal
That is the loop if you need to access your index (cx). If you just wanna to something 0-3=4 times but you do not need the index, this would be easier:
mov cx,4 ; 4 iterations
loop1 nop ; Whatever you wanna do goes here, should not change cx
loop loop1 ; loop instruction decrements cx and jumps to label if not 0
If you just want to perform a very simple instruction a constant amount of times, you could also use an assembler-directive which will just hardcore that instruction
times 4 nop
Do-while-loop in C:
int x=1;
do{
//Do something!
}
while(x==1)
The same loop in assembler:
mov ax,1
loop1 nop ; Whatever you wanna do goes here
cmp ax,1 ; Check wether cx is 1
je loop1 ; And loop if equal
While-loop in C:
while(x==1){
//Do something
}
The same loop in assembler:
jmp loop1 ; Jump to condition first
cloop1 nop ; Execute the content of the loop

For the for-loops you should take the cx-register because it is pretty much standard. For the other loop conditions you can take a register of your liking. Of course replace the no-operation instruction with all the instructions you wanna perform in the loop.
I'm not sure why your current code is failing (what is the Exception you get?), but I would like to point out this approach performs O(N-squared). Consider pre-sorting your input arrays (if they are not defined to be pre-sorted) and merging the sorted arrays:
http://www.algolist.net/Algorithms/Merge/Sorted_arrays
Sorting is generally O(N logN) and the merge is O(m+n).
I think you have to options:
Build a dynamic SQL using sys.tables
and sys.columns
to perform the search (example here).
Use any program that have this function. An example of this is SQL Workbench (free).
Yes, the order of elements in JSON arrays is preserved. From RFC 7159 -The JavaScript Object Notation (JSON) Data Interchange Format (emphasis mine):
An object is an unordered collection of zero or more name/value pairs, where a name is a string and a value is a string, number, boolean, null, object, or array.
An array is an ordered sequence of zero or more values.
The terms "object" and "array" come from the conventions of JavaScript.
Some implementations do also preserve the order of JSON objects as well, but this is not guaranteed.
Static Memory Allocation:
Dynamic Memory Allocation:
You cannot always make a branch or pull an existing branch and push back to it, because you are not registered as a collaborator for that specific project.
Forking is nothing more than a clone on the GitHub server side:
You keep a fork in sync with the original project by:
The rebase allows you to make sure your changes are straightforward (no merge conflict to handle), making your pulling request that more easy when you want the maintainer of the original project to include your patches in his project.
The goal is really to allow collaboration even though direct participation is not always possible.
The fact that you clone on the GitHub side means you have now two "central" repository ("central" as "visible from several collaborators).
If you can add them directly as collaborator for one project, you don't need to manage another one with a fork.
The merge experience would be about the same, but with an extra level of indirection (push first on the fork, then ask for a pull, with the risk of evolutions on the original repo making your fast-forward merges not fast-forward anymore).
That means the correct workflow is to git pull --rebase upstream
(rebase your work on top of new commits from upstream), and then git push --force origin
, in order to rewrite the history in such a way your own commits are always on top of the commits from the original (upstream) repo.

you can delete the corresponding failed artifact directory in you local repository. And also you can simply use the -U
in the goal. It will do the work. This works with maven 3. So no need to downgrade to maven 2.
I have studied a number of Go projects and there is a fair bit of variation. You can kind of tell who is coming from C and who is coming from Java, as the former dump just about everything in the projects root directory in a main
package, and the latter tend to put everything in a src
directory. Neither is optimal however. Each have consequences because they affect import paths and how others can reuse them.
To get the best results I have worked out the following approach.
myproj/
main/
mypack.go
mypack.go
Where mypack.go
is package mypack
and main/mypack.go
is (obviously) package main
.
If you need additional support files you have two choices. Either keep them all in the root directory, or put private support files in a lib
subdirectory. E.g.
myproj/
main/
mypack.go
myextras/
someextra.go
mypack.go
mysupport.go
Or
myproj.org/
lib/
mysupport.go
myextras/
someextra.go
main/
mypack.go
mypage.go
Only put the files in a lib
directory if they are not intended to be imported by another project. In other words, if they are private support files. That's the idea behind having lib
--to separate public from private interfaces.
Doing things this way will give you a nice import path, myproj.org/mypack
to reuse the code in other projects. If you use lib
then internal support files will have an import path that is indicative of that, myproj.org/lib/mysupport
.
When building the project, use main/mypack
, e.g. go build main/mypack
. If you have more than one executable you can also separate those under main
without having to create separate projects. e.g. main/myfoo/myfoo.go
and main/mybar/mybar.go
.
Docstrings (and documentation in general). Python 3 introduces (optional) function annotations, as described in PEP 3107 (but don't leave out docstrings)
while spring.jpa.open-in-view was true, I didn't have any problem with getOne but after setting it to false , i got LazyInitializationException. Then problem was solved by replacing with findById.
Although there is another solution without replacing the getOne method, and that is put @Transactional at method which is calling repository.getOne(id). In this way transaction will exists and session will not be closed in your method and while using entity there would not be any LazyInitializationException.

They are the same but the second one is great if you have MVC in your code and don't want to have a lot of echos in your code. For example, in my .phtml
files (Zend Framework) I will write something like this:
<?php if($this->value): ?>
Hello
<?php elseif($this->asd): ?>
Your name is: <?= $this->name ?>
<?php else: ?>
You don't have a name.
<?php endif; ?>
If you are using the IN operator, the SQL engine will scan all records fetched from the inner query. On the other hand if we are using EXISTS, the SQL engine will stop the scanning process as soon as it found a match.

In python automatic garbage collection deallocates the variable (pandas DataFrame are also just another object in terms of python). There are different garbage collection strategies that can be tweaked (requires significant learning).
You can manually trigger the garbage collection using
import gc
gc.collect()
But frequent calls to garbage collection is discouraged as it is a costly operation and may affect performance.
Please try the following code below:
//Here I am using a reader object to fetch data from database, along with sqlcommand onject (cmd).
//Once the data is loaded to the Datatable object (datatable) you can loop through it using the datatable.rows.count prop.
using (reader = cmd.ExecuteReader())
{
// Load the Data table object
dataTable.Load(reader);
if (dataTable.Rows.Count > 0)
{
DataColumn col = dataTable.Columns["YourColumnName"];
foreach (DataRow row in dataTable.Rows)
{
strJsonData = row[col].ToString();
}
}
}
Try this general approach:
import re
my_string="hello python world , i'm a beginner "
p = re.compile("world(.*)")
print (p.findall(my_string))
#[" , i'm a beginner "]
On macOS Sierra you need to run:
sudo chown -R $(whoami):staff /usr/local
You can always just export the HTML table to an XLS document. Excel does a pretty good job understanding HTML tables.
Another possiblitly is to export the HTML tables as a CSV or TSV file, but you would need to setup the formatting in your code. This isn't too difficult to accomplish.
There's some classes in the Microsoft.Office.Interop that allow you to create an Excel file programatically, but I have always found them to be a little clumsy. You can find a .NET version of creating a spreadsheet here, which should be pretty easy to modify for classic ASP.
As for .NET, I've always liked CarlosAG's Excel XML Writer Library. It has a nice generator so you can setup your Excel file, save it as an XML spreadsheet and it generates the code to do all the formatting and everything. I know it's not classic ASP, but I thought that I would throw it out there.
With what you're trying above, try adding the header:
"Content-Disposition", "attachment; filename=excelTest.xls"
See if that works. Also, I always use this for the content type:
Response.ContentType = "application/octet-stream"
Response.ContentType = "application/vnd.ms-excel"
I know this is probably going to cause an unnecessary flame war, but I can see how you might want more than one database connection, so I would concede the point that singleton might not be the best solution for that... however, there are other uses of the singleton pattern that I find extremely useful.
Here's an example: I decided to roll my own MVC and templating engine because I wanted something really lightweight. However, the data that I want to display contains a lot of special math characters such as ≥ and μ and what have you... The data is stored as the actual UTF-8 character in my database rather than pre-HTML-encoded because my app can deliver other formats such as PDF and CSV in addition to HTML. The appropriate place to format for HTML is inside the template ("view" if you will) that is responsible for rendering that page section (snippet). I want to convert them to their appropriate HTML entities, but PHPs get_html_translation_table() function is not super fast. It makes better sense to retrieve the data one time and store as an array, making it available for all to use. Here's a sample I knocked together to test the speed. Presumably, this would work regardless of whether the other methods you use (after getting the instance) were static or not.
class EncodeHTMLEntities {
private static $instance = null;//stores the instance of self
private $r = null;//array of chars elligalbe for replacement
private function __clone(){
}//disable cloning, no reason to clone
private function __construct()
{
$allEntities = get_html_translation_table(HTML_ENTITIES, ENT_NOQUOTES);
$specialEntities = get_html_translation_table(HTML_SPECIALCHARS, ENT_NOQUOTES);
$this->r = array_diff($allEntities, $specialEntities);
}
public static function replace($string)
{
if(!(self::$instance instanceof self) ){
self::$instance = new self();
}
return strtr($string, self::$instance->r);
}
}
//test one million encodings of a string
$start = microtime(true);
for($x=0; $x<1000000; $x++){
$dump = EncodeHTMLEntities::replace("Reference method for diagnosis of CDAD, but clinical usefulness limited due to extended turnaround time (=96 hrs)");
}
$end = microtime(true);
echo "Run time: ".($end-$start)." seconds using singleton\n";
//now repeat the same without using singleton
$start = microtime(true);
for($x=0; $x<1000000; $x++){
$allEntities = get_html_translation_table(HTML_ENTITIES, ENT_NOQUOTES);
$specialEntities = get_html_translation_table(HTML_SPECIALCHARS, ENT_NOQUOTES);
$r = array_diff($allEntities, $specialEntities);
$dump = strtr("Reference method for diagnosis of CDAD, but clinical usefulness limited due to extended turnaround time (=96 hrs)", $r);
}
$end = microtime(true);
echo "Run time: ".($end-$start)." seconds without using singleton";
Basically, I saw typical results like this:
php test.php Run time: 27.842966794968 seconds using singleton Run time: 237.78191494942 seconds without using singleton
So while I'm certainly no expert, I don't see a more convenient and reliable way to reduce the overhead of slow calls for some kind of data, while making it super simple (single line of code to do what you need). Granted my example only has one useful method, and therefore is no better than a globally defined function, but as soon as you have two methods, you're going to want to group them together, right? Am I way off base?
Also, I prefer examples that actually DO something, since sometimes it's hard to visualise when an example includes statements like "//do something useful here" which I see all the time when searching for tutorials.
Anyway, I'd love any feedback or comments on why using a singleton for this type of thing is detrimental (or overly complicated).
This can happen when you added Core Data to an existing project.
Check the:
<Name>/<Name>.xcdatamodeld/<Name>.xcdatamodel/contents
file.
This file contains an entry "sourceLanguage" that (by default) might have been set to "Swift". Change it to "Objective-C".
public ActionResult Index()
{
List<CustomerOrder_Result> obj = new List<CustomerOrder_Result>();
var orderlist = (from a in db.OrderMasters
join b in db.Customers on a.CustomerId equals b.Id
join c in db.CustomerAddresses on b.Id equals c.CustomerId
where a.Status == "Pending"
select new
{
Customername = b.Customername,
Phone = b.Phone,
OrderId = a.OrderId,
OrderDate = a.OrderDate,
NoOfItems = a.NoOfItems,
Order_amt = a.Order_amt,
dis_amt = a.Dis_amt,
net_amt = a.Net_amt,
status=a.Status,
address = c.address,
City = c.City,
State = c.State,
Pin = c.Pin
}) ;
foreach (var item in orderlist)
{
CustomerOrder_Result clr = new CustomerOrder_Result();
clr.Customername=item.Customername;
clr.Phone = item.Phone;
clr.OrderId = item.OrderId;
clr.OrderDate = item.OrderDate;
clr.NoOfItems = item.NoOfItems;
clr.Order_amt = item.Order_amt;
clr.net_amt = item.net_amt;
clr.address = item.address;
clr.City = item.City;
clr.State = item.State;
clr.Pin = item.Pin;
clr.status = item.status;
obj.Add(clr);
}
The proper way that actually works:
URL resource = YourClass.class.getResource("abc");
Paths.get(resource.toURI()).toFile();
It doesn't matter now where the file in the classpath physically is, it will be found as long as the resource is actually a file and not a JAR entry.
(The seemingly obvious new File(resource.getPath())
doesn't work for all paths! The path is still URL-encoded!)
Use the pow(x,y) function: See Here
Just include math.h and you're all set.
Just include SizeToReportContent="true"
as shown below
<rsweb:ReportViewer ID="ReportViewer1" runat="server" SizeToReportContent="True"...
List<String> list = new ArrayList<>();
list.add("Hello");
list.add("Hello");
list.add("World");
Map<String, List<String>> collect = list.stream()
.collect(Collectors.groupingBy(o -> o));
collect.entrySet()
.forEach(e -> System.out.println(e.getKey() + " - " + e.getValue().size()));
Couldn't you just create a record in a separate table or whatever with a column called Users and UPDATE it with the last inserted id on User Registration?
Then you would just check this field with a simple query.
It might be rough but it would work perfectly.
To clear your form, admitted that your form's elements values are saved in your state, you can map through your state like that :
// clear all your form
Object.keys(this.state).map((key, index) => {
this.setState({[key] : ""});
});
If your form is among other fields, you can simply insert them in a particular field of the state like that:
state={
form: {
name:"",
email:""}
}
// handle set in nested objects
handleChange = (e) =>{
e.preventDefault();
const newState = Object.assign({}, this.state);
newState.form[e.target.name] = e.target.value;
this.setState(newState);
}
// submit and clear state in nested object
onSubmit = (e) =>{
e.preventDefault();
var form = Object.assign({}, this.state.form);
Object.keys(form).map((key, index) => {
form[key] = "" ;
});
this.setState({form})
}
You can set default values using Class
.
interface IModal {
content: string;
form: string;
href: string;
isPopup: boolean;
};
class Modal implements IModal {
content = "";
form = "";
href: string; // will not be added to object
isPopup = true;
}
const myModal = new Modal();
console.log(myModal); // output: {content: "", form: "", isPopup: true}
interface IModal {
content: string;
form: string;
href: string;
isPopup: boolean;
}
class Modal implements IModal {
constructor() {
this.content = "";
this.form = "";
this.isPopup = true;
}
content: string;
form: string;
href: string; // not part of constructor so will not be added to object
isPopup: boolean;
}
const myModal = new Modal();
console.log(myModal); // output: {content: "", form: "", isPopup: true}
The recent versions of XAMPP for Windows runs PHP 7.x which are NOT compatible with mbcrypt. If you have a package like Laravel that requires mbcrypt, you will need to install an older version of XAMPP. OR, you can run XAMPP with multiple versions of PHP by downloading a PHP package from Windows.PHP.net, installing it in your XAMPP folder, and configuring php.ini and httpd.conf to use the correct version of PHP for your site.
I found this wonderful mapping script (mapper.js) that I have used in the past. What's different about it is you can hover over the map or a link on your page to make the map area highlight. Sadly it's written in javascript and requires a lot of in-line coding in the HTML - I would love to see this script ported over to jQuery :P
Also, check out all the demos! I think this example could almost be made into a simple online game (without using flash) - make sure you click on the different camera angles.
It is going to be prettier if you format the seconds output like:
echo "Process took ". number_format(microtime(true) - $start, 2). " seconds.";
will print
Process took 6.45 seconds.
This is much better than
Process took 6.4518549156189 seconds.
As I mentioned in this thread I tend to use Jersey which implements JAX-RS and comes with a nice REST client. The nice thing is if you implement your RESTful resources using JAX-RS then the Jersey client can reuse the entity providers such as for JAXB/XML/JSON/Atom and so forth - so you can reuse the same objects on the server side as you use on the client side unit test.
For example here is a unit test case from the Apache Camel project which looks up XML payloads from a RESTful resource (using the JAXB object Endpoints). The resource(uri) method is defined in this base class which just uses the Jersey client API.
e.g.
clientConfig = new DefaultClientConfig();
client = Client.create(clientConfig);
resource = client.resource("http://localhost:8080");
// lets get the XML as a String
String text = resource("foo").accept("application/xml").get(String.class);
BTW I hope that future version of JAX-RS add a nice client side API along the lines of the one in Jersey
I always write what I would use if there was no interface and I was writing a direct implementation, i.e., I would use public
.
In this specific context, your example doesn't make a lot of sense.
When a Being picks up an Item, the item retains an individual existence. It doesn't disappear because it's been picked up. It still exists, but it's (a) in the same location as the Being, and (b) no longer eligible to be picked up. While it's had a state change, it still exists.
There is a two-way association between Being and Item. The Being has the Item in a collection. The Item is associated with a Being.
When an Item is picked up by a Being, two things have to happen.
The Being how adds the Item in some set
of items. Your bag
attribute, for example, could be such a set
. [A list
is a poor choice -- does order matter in the bag?]
The Item's location changes from where it used to be to the Being's location. There are probably two classes os Items - those with an independent sense of location (because they move around by themselves) and items that have to delegate location to the Being or Place where they're sitting.
Under no circumstances does any Python object ever need to get deleted. If an item is "destroyed", then it's not in a Being's bag. It's not in a location.
player.bag.remove(cat)
Is all that's required to let the cat out of the bag. Since the cat is not used anywhere else, it will both exist as "used" memory and not exist because nothing in your program can access it. It will quietly vanish from memory when some quantum event occurs and memory references are garbage collected.
On the other hand,
here.add( cat )
player.bag.remove(cat)
Will put the cat in the current location. The cat continues to exist, and will not be put out with the garbage.

// this method can be used to access other request headers like, 'Referer', 'User-Agent' etc.
I came across this error and took some time to resolve it. In my case I had https and net.tcp configured as IIS bindings on same port. Obviously you can't have two things on the same port. I used netstat -ap tcp command to check whether there is something listening on that port. There was none listening. Removing unnecessary binding (https in my case) solved my issue.
The Material Design Typography page has demos for some of these fonts and suggestions on choosing fonts and styles.
For code sleuths: fonts.xml
is the definitive and ever-expanding list of Android fonts.
Set the android:fontFamily
and android:textStyle
attributes, e.g.
<!-- Roboto Bold -->
<TextView
android:fontFamily="sans-serif"
android:textStyle="bold" />
to the desired values from this table:
Font | android:fontFamily | android:textStyle
-------------------------|-----------------------------|-------------------
Roboto Thin | sans-serif-thin |
Roboto Light | sans-serif-light |
Roboto Regular | sans-serif |
Roboto Bold | sans-serif | bold
Roboto Medium | sans-serif-medium |
Roboto Black | sans-serif-black |
Roboto Condensed Light | sans-serif-condensed-light |
Roboto Condensed Regular | sans-serif-condensed |
Roboto Condensed Medium | sans-serif-condensed-medium |
Roboto Condensed Bold | sans-serif-condensed | bold
Noto Serif | serif |
Noto Serif Bold | serif | bold
Droid Sans Mono | monospace |
Cutive Mono | serif-monospace |
Coming Soon | casual |
Dancing Script | cursive |
Dancing Script Bold | cursive | bold
Carrois Gothic SC | sans-serif-smallcaps |
(Noto Sans is a fallback font; you can't specify it directly)
Note: this table is derived from fonts.xml
. Each font's family name and style is listed in fonts.xml, e.g.
<family name="serif-monospace">
<font weight="400" style="normal">CutiveMono.ttf</font>
</family>
serif-monospace
is thus the font family, and normal
is the style.
Based on the log of fonts.xml and the former system_fonts.xml, you can see when each font was added:
Unique views is always a hard nut to crack. Checking the IP might work, but an IP can be shared by more than one user. A cookie could be a viable option, but a cookie can expire or be modified by the client.
In your case, it don't seem to be a big issue if the cookie is modified tho, so i would recommend using a cookie in a case like this. When the page is loaded, check if there is a cookie, if there is not, create one and add a +1 to views. If it is set, don't do the +1.
Set the cookies expiration date to whatever you want it to be, week or day if that's what you want, and it will expire after that time. After expiration, it will be a unique user again!
Edit:
Thought it might be a good idea to add this notice here...
Since around the end of 2016 a IP address (static or dynamic) is seen as personal data in the EU.
That means that you are only allowed to store a IP address with a good reason (and I'm not sure if tracking views is a good reason). So if you intend to store the IP address of visitors, I would recommend hashing or encrypting it with a algorithm which can not be reversed, to make sure that you are not breaching any law (especially after the GDPR laws have been implemented).
Ambers's solution also works well for numpy arrays:
from pylab import *
import csv
array_=arange(0,10,1)
list_=[array_,array_*2,array_*3]
with open("output.csv", "wb") as f:
writer = csv.writer(f)
writer.writerows(list_)
This works. Try it.
<BODY ondragstart="return false;" ondrop="return false;">
Because font doesn't have color, you need a panel to make a backgound color and give the foreground color for both JLabel (if you use JLabel) and JPanel to make font color, like example below :
JLabel lblusr = new JLabel("User name : ");
lblusr.setForeground(Color.YELLOW);
JPanel usrPanel = new JPanel();
Color maroon = new Color (128, 0, 0);
usrPanel.setBackground(maroon);
usrPanel.setOpaque(true);
usrPanel.setForeground(Color.YELLOW);
usrPanel.add(lblusr);
The background color of label is maroon with yellow font color.
Change =
to ==
i.e
if (strcmp("hello", "hello") == 0)
You want to compare the result of strcmp()
to 0. So you need ==
. Assigning it to 0 won't work because rvalues cannot be assigned to.
I have the same problem as @KTCheek in that I need it to execute sequentially. However I figured I would try using IAsyncEnumerable (introduced in .NET Core 3) and await foreach (introduced in C# 8). Here's what I have come up with:
public static class IEnumerableExtensions {
public static async IAsyncEnumerable<TResult> SelectAsync<TSource, TResult>(this IEnumerable<TSource> source, Func<TSource, Task<TResult>> selector) {
foreach (var item in source) {
yield return await selector(item);
}
}
}
public static class IAsyncEnumerableExtensions {
public static async Task<List<TSource>> ToListAsync<TSource>(this IAsyncEnumerable<TSource> source) {
var list = new List<TSource>();
await foreach (var item in source) {
list.Add(item);
}
return list;
}
}
This can be consumed by saying:
var inputs = await events.SelectAsync(ev => ProcessEventAsync(ev)).ToListAsync();
Update: Alternatively you can add a reference to "System.Linq.Async" and then you can say:
var inputs = await events
.ToAsyncEnumerable()
.SelectAwait(async ev => await ProcessEventAsync(ev))
.ToListAsync();
1st option
select *
into ABC_1

2nd option: use SSIS, that is right click on database in object explorer > all tasks > export data

Because the bootstrap-select is a bootstrap component and therefore you need to include it in your code as you did for your V3
NOTE: this component only works in boostrap-4 since version 1.13.0

If you just don't need anything as your type, you can use void. This can be used for implementing functions, or actions. You could then do something like this:
interface Action<T> {
public T execute();
}
abstract class VoidAction implements Action<Void> {
public Void execute() {
executeInternal();
return null;
}
abstract void executeInternal();
}
Or you could omit the abstract class, and do the return null in every action that doesn't require a return value yourself.
You could then use those actions like this:
Given a method
private static <T> T executeAction(Action<T> action) {
return action.execute();
}
you can call it like
String result = executeAction(new Action<String>() {
@Override
public String execute() {
//code here
return "Return me!";
}
});
or, for the void action (note that you're not assigning the result to anything)
executeAction(new VoidAction() {
@Override
public void executeInternal() {
//code here
}
});
I had tried almost all the above methods.
Finally fixed it by including the
script src="{%static 'App/js/jquery.js' %}"
just after loading the staticfiles i.e {% load staticfiles %}
in base.html
I believe this has been answered in some sections already, just test with gmail for your "MAIL_HOST" instead and don't forget to clear cache. Setup like below: Firstly, you need to setup 2 step verification here google security. An App Password link will appear and you can get your App Password to insert into below "MAIL_PASSWORD". More info on getting App Password here

If you have Mac OS X, go to the file root or the folder of your website.
Then right-hand click on it, go to get information, go to the very bottom (Sharing & Permissions), open that, change all read-only to read and write. Make sure to open padlock, go to setting icon, and choose Apply to the enclosed items...
You may also use the .jquery property as described here: http://api.jquery.com/jquery-2/
var a = { what: "A regular JS object" },
b = $('body');
if ( a.jquery ) { // falsy, since it's undefined
alert(' a is a jQuery object! ');
}
if ( b.jquery ) { // truthy, since it's a string
alert(' b is a jQuery object! ');
}
Assuming that "a" and "b" are bean properties
rendered="#{bean.a==12 and (bean.b==13 or bean.b==15)}"
You may look at JSF EL operators
If you have cygwin installed, from it's bash shell, run your executable, say MyProgram
, using the time
utility, like so:
/usr/bin/time ./MyProgram
This will report how long the execution of your program took -- the output would look something like the following:
real 0m0.792s
user 0m0.046s
sys 0m0.218s
You could also manually modify your C program to instrument it using the clock()
library function, like so:
#include <time.h>
int main(void) {
clock_t tStart = clock();
/* Do your stuff here */
printf("Time taken: %.2fs\n", (double)(clock() - tStart)/CLOCKS_PER_SEC);
return 0;
}
I can't seem to wrap my head around why this does not work.
Because main
returns a promise; all async
functions do.
At the top level, you must either:
Use a top-level async
function that never rejects (unless you want "unhandled rejection" errors), or
Use then
and catch
, or
(Coming soon!) Use top-level await
, a proposal that has reached Stage 3 in the process that allows top-level use of await
in a module.
async
function that never rejects(async () => {
try {
var text = await main();
console.log(text);
} catch (e) {
// Deal with the fact the chain failed
}
})();
Notice the catch
; you must handle promise rejections / async exceptions, since nothing else is going to; you have no caller to pass them on to. If you prefer, you could do that on the result of calling it via the catch
function (rather than try
/catch
syntax):
(async () => {
var text = await main();
console.log(text);
})().catch(e => {
// Deal with the fact the chain failed
});
...which is a bit more concise (I like it for that reason).
Or, of course, don't handle errors and just allow the "unhandled rejection" error.
then
and catch
main()
.then(text => {
console.log(text);
})
.catch(err => {
// Deal with the fact the chain failed
});
The catch
handler will be called if errors occur in the chain or in your then
handler. (Be sure your catch
handler doesn't throw errors, as nothing is registered to handle them.)
Or both arguments to then
:
main().then(
text => {
console.log(text);
},
err => {
// Deal with the fact the chain failed
}
);
Again notice we're registering a rejection handler. But in this form, be sure that neither of your then
callbacks doesn't throw any errors, nothing is registered to handle them.
await
in a moduleYou can't use await
at the top level of a non-module script, but the top-level await
proposal (Stage 3) allows you to use it at the top level of a module. It's similar to using a top-level async
function wrapper (#1 above) in that you don't want your top-level code to reject (throw an error) because that will result in an unhandled rejection error. So unless you want to have that unhandled rejection when things go wrong, as with #1, you'd want to wrap your code in an error handler:
// In a module, once the top-level `await` proposal lands
try {
var text = await main();
console.log(text);
} catch (e) {
// Deal with the fact the chain failed
}
Note that if you do this, any module that imports from your module will wait until the promise you're await
ing settles; when a module using top-level await
is evaluated, it basically returns a promise to the module loader (like an async
function does), which waits until that promise is settled before evaluating the bodies of any modules that depend on it.
You can also use the .btn-block
class on the button, so that it expands to the parent's width.
If the parent is a fixed width element the button will expand to take all width. You can apply existing markup to the container to ensure fixed/fluid buttons take up only the required space.

Allan Jardine’s DataTables is a very powerful and slick jQuery plugin for displaying tabular data. It has many features and can do most of what you might want. One thing that’s curiously difficult though, is how to refresh the contents in a simple way, so I for my own reference, and possibly for the benefit of others as well, here’s a complete example of one way if doing this:
HTML
<table id="HelpdeskOverview">
<thead>
<tr>
<th>Ärende</th>
<th>Rapporterad</th>
<th>Syst/Utr/Appl</th>
<th>Prio</th>
<th>Rubrik</th>
<th>Status</th>
<th>Ägare</th>
</tr>
</thead>
<tbody>
</tbody>
</table>
Javascript
function InitOverviewDataTable()
{
oOverviewTable =$('#HelpdeskOverview').dataTable(
{
"bPaginate": true,
"bJQueryUI": true, // ThemeRoller-stöd
"bLengthChange": false,
"bFilter": false,
"bSort": false,
"bInfo": true,
"bAutoWidth": true,
"bProcessing": true,
"iDisplayLength": 10,
"sAjaxSource": '/Helpdesk/ActiveCases/noacceptancetest'
});
}
function RefreshTable(tableId, urlData)
{
$.getJSON(urlData, null, function( json )
{
table = $(tableId).dataTable();
oSettings = table.fnSettings();
table.fnClearTable(this);
for (var i=0; i<json.aaData.length; i++)
{
table.oApi._fnAddData(oSettings, json.aaData[i]);
}
oSettings.aiDisplay = oSettings.aiDisplayMaster.slice();
table.fnDraw();
});
}
function AutoReload()
{
RefreshTable('#HelpdeskOverview', '/Helpdesk/ActiveCases/noacceptancetest');
setTimeout(function(){AutoReload();}, 30000);
}
$(document).ready(function () {
InitOverviewDataTable();
setTimeout(function(){AutoReload();}, 30000);
});
In my case symbolicating was take forever. I force restart my phone with both of on/off and home button. Now quickly finished symbolicating and I am starting run my app via xcode.
I may be late, but you can try the following code, which worked for me for Drag and Drop.
.dndclass{
cursor: url('../images/grab1.png'), auto;
}
.dndclass:active {
cursor: url('../images/grabbing1.png'), auto;
}
You can use the images below in the URL above. Make sure it is a PNG transparent image. If not, download one from google.
We are using the following that works both python 2 and python 3
#Works in Python 2 and 3:
try: input = raw_input
except NameError: pass
print(input("Enter your name: "))
View > Tool Windows > Device File Explorer
Step 1
Go to Help --->
Install New Software...
Step 2 Try to find "http://download.eclipse.org/webtools/updates" under work with drop down. If you find then select and install all the available updates.
If you can not find then click on Add -> Add Repository. Name: Eclipse Webtools Location: http://download.eclipse.org/webtools/updates Select all available updates and Install them.
Visit http://download.eclipse.org/webtools/updates/ for more details.
For example, your controller, retrive data and put the view
class ClassExampleController extends Controller
{
public function index()
{
$test = Test::first(1);
return view('view-form',[
'field' => $test,
]);
}
}
Add default value in the same form, create and edit, is very simple
<!-- view-form file -->
<form action="{{
isset($field) ?
@route('field.updated', $field->id) :
@route('field.store')
}}">
<!-- Input case -->
<input name="name_input" class="form-control"
value="{{ isset($field->name) ? $field->name : '' }}">
</form>
And, you remember add csrf_field, in case a POST method requesting. Therefore, repeat input, and select element, compare each option
<select name="x_select">
@foreach($field as $subfield)
@if ($subfield == $field->name)
<option val="i" checked>
@else
<option val="i" >
@endif
@endforeach
</select>
You use runas
to launch a program as a specific user:
runas /user:Administrator Example1Server.exe
using javascript
<form id="frm1" action="file.php"></form>
<script>document.getElementById('frm1').submit();</script>
In addition to what was already said - in order to avoid this error from interfering (stopping) other Javascript code on your page, you could try forcing the YouTube iframe to load last - after all other Javascript code is loaded.
I'd recommend you to try http://faviconer.com to convert your .PNG or .GIF to a .ICO file.
You can create both 16x16
and 32x32
(for new retina display) in one .ICO file.
No issues with IE and Firefox
NSString *stringA;
NSString *stringB;
if (stringA && [stringA caseInsensitiveCompare:stringB] == NSOrderedSame) {
// match
}
Note: stringA &&
is required because when stringA
is nil
:
stringA = nil;
[stringA caseInsensitiveCompare:stringB] // return 0
and so happens NSOrderedSame
is also defined as 0
.
The following example is a typical pitfall:
NSString *rank = [[NSUserDefaults standardUserDefaults] stringForKey:@"Rank"];
if ([rank caseInsensitiveCompare:@"MANAGER"] == NSOrderedSame) {
// what happens if "Rank" is not found in standardUserDefaults
}
You can only do this to you own photos. Due to recent upgrades, Facebook has made this more difficult. To do this, go to the album page where the photo is that you want to link to. You should see thumbnail images of the photos in the album. Hold down the "Control" or "Command" key while clicking the photo that you wish to link to. A new browser tab will open with the picture you clicked. Under the picture there is a URL that you can send to others to share the photo. You might have to have the privacy settings for that album set so that anyone can see the photos in that album. If you don't the person who clicks the link may have to be signed in and also be your "friend."
Here is an example of one of my photos: http://www.facebook.com/photo.php?pid=43764341&l=0d8a526a64&id=25502298 -it's my cat.
Update:
The link below the photo no longer appears. Once you open the photo in a new tab you can right click the photo (Control+click for Mac users) and click "Copy Image URL" or similar and then share this link. Based on my tests the person who clicks the link doesn't need to use Facebook. The photo will load without the Facebook interface. Like this - http://a1.sphotos.ak.fbcdn.net/hphotos-ak-ash4/189088_867367406856_25502298_43764341_1304758_n.jpg
The standard way to parse JSON in JavaScript is JSON.parse()
The JSON
API was introduced with ES5 (2011) and has since been implemented in >99% of browsers by market share, and Node.js. Its usage is simple:
const json = '{ "fruit": "pineapple", "fingers": 10 }';
const obj = JSON.parse(json);
console.log(obj.fruit, obj.fingers);
_x000D_
The only time you won't be able to use JSON.parse()
is if you are programming for an ancient browser, such as IE 7 (2006), IE 6 (2001), Firefox 3 (2008), Safari 3.x (2009), etc. Alternatively, you may be in an esoteric JavaScript environment that doesn't include the standard APIs. In these cases, use json2.js, the reference implementation of JSON written by Douglas Crockford, the inventor of JSON. That library will provide an implementation of JSON.parse()
.
When processing extremely large JSON files, JSON.parse()
may choke because of its synchronous nature and design. To resolve this, the JSON website recommends third-party libraries such as Oboe.js and clarinet, which provide streaming JSON parsing.
jQuery once had a $.parseJSON()
function, but it was deprecated with jQuery 3.0. In any case, for a long time, it was nothing more than a wrapper around JSON.parse()
.
An alternative method is to use a Grid with one column and n rows. Set all the rows heights to Auto
, and the bottom-most row height to 1*
.
I prefer this method because I've found Grids have better layout performance than DockPanels, StackPanels, and WrapPanels. But unless you're using them in an ItemTemplate (where the layout is being performed for a large number of items), you'll probably never notice.
user334291's answer was a life saver for me. Just want to add how you can add what the OP originally intended to do (what I ended up using):
Overriding the GetWebRequest function on the generated webservice code:
protected override System.Net.WebRequest GetWebRequest(Uri uri)
{
System.Net.WebRequest request = base.GetWebRequest(uri);
string auth = "Basic " + Convert.ToBase64String(System.Text.Encoding.Default.GetBytes(this.Credentials.GetCredential(uri, "Basic").UserName + ":" + this.Credentials.GetCredential(uri, "Basic").Password));
request.Headers.Add("Authorization", auth);
return request;
}
and setting the credentials before calling the webservice:
client.Credentials = new NetworkCredential(user, password);
Try na.omit(your.data.frame)
. As for the second question, try posting it as another question (for clarity).
Instead of calling /usr/bin/gcc
, use /usr/bin/c99
. This is the Single-Unix-approved way of invoking a C99 compiler. On an Ubuntu system, this points to a script which invokes gcc
after having added the -std=c99
flag, which is precisely what you want.
Lets talk about different scope in 'C'
SCOPE: It is basically how long can I see something and how far.
Local variable : Scope is only inside a function. It resides in the STACK area of RAM. Which means that every time a function gets called all the variables that are the part of that function, including function arguments are freshly created and are destroyed once the control goes out of the function. (Because the stack is flushed every time function returns)
Static variable: Scope of this is for a file. It is accessible every where in the file
in which it is declared. It resides in the DATA segment of RAM. Since
this can only be accessed inside a file and hence INTERNAL linkage. Any
other files cannot see this variable. In fact STATIC keyword is the
only way in which we can introduce some level of data or function
hiding in 'C'
Global variable: Scope of this is for an entire application. It is accessible form every where of the application. Global variables also resides in DATA segment Since it can be accessed every where in the application and hence EXTERNAL Linkage
By default all functions are global. In case, if you need to hide some functions in a file from outside, you can prefix the static keyword to the function. :-)
nobr is too unreliable, use tables
<table>
<tr>
<td> something </td>
<td> something </td>
</tr>
</table>
It all goes on the same line, everything is level with eachother, and you have much more freedom if you want to change something later.
Parsing is just process of analyse the string of character and find the tokens from that string and parser is a component of interpreter and compiler.It uses lexical analysis and then syntactic analysis.It parse it and then compile this code after this whole process of compilation.
You can use the Mock.call_args_list
attribute to compare parameters to previous method calls. That in conjunction with Mock.call_count
attribute should give you full control.
first up on create your jsp file :
and write the text field which you want
for ex:
after that create your servlet class:
public class test{
protected void doGet(paramter , paramter){
String name = request.getparameter("name");
}
}
For one, you can't modify string literals. It's undefined behavior.
To fix that you can make str
a local array:
char str[] = "First string";
Now, you will have a second problem, is that str
isn't large enough to hold str2
. So you will need to increase the length of it. Otherwise, you will overrun str
- which is also undefined behavior.
To get around this second problem, you either need to make str
at least as long as str2
. Or allocate it dynamically:
char *str2 = "Second string";
char *str = malloc(strlen(str2) + 1); // Allocate memory
// Maybe check for NULL.
strcpy(str, str2);
// Always remember to free it.
free(str);
There are other more elegant ways to do this involving VLAs (in C99) and stack allocation, but I won't go into those as their use is somewhat questionable.
As @SangeethSaravanaraj pointed out in the comments, everyone missed the #import
. It should be #include
:
#include <stdio.h>
#include <string.h>
It's probably the same problem with cultures as presented in this related SO-thread: Why can't DateTime.ParseExact() parse "9/1/2009" using "M/d/yyyy"
You already specified the culture, so try escaping the slashes.
Its also interesting to observe this
To iterate over the indices of a sequence, you can combine range()
and len()
as follows:
a = ['Mary', 'had', 'a', 'little', 'lamb']
for i in range(len(a)):
print(i, a[i])
output
0 Mary
1 had
2 a
3 little
4 lamb
Edit#1: Alternate way:
When looping through a sequence, the position index and corresponding value can be retrieved at the same
time using the enumerate()
function.
for i, v in enumerate(['tic', 'tac', 'toe']):
print(i, v)
output
0 tic
1 tac
2 toe
File 1
class ClassA {
public $name = 'A';
public function getName(){
return $this->name;
}
}
File 2
include("file1.php");
class ClassB {
public $name = 'B';
public function getName(){
return $this->name;
}
public function callA(){
$a = new ClassA();
return $a->getName();
}
public static function callAStatic(){
$a = new ClassA();
return $a->getName();
}
}
$b = new ClassB();
echo $b->callA();
echo $b->getName();
echo ClassB::callAStatic();
Try it ..
UPDATE PRODUCTION a

i work on a multi platform project, so i can't use _s function and i don't want pollute my code with visual studio specific code.
my solution is disable the warning 4996 on the visual studio project. go to Project -> Properties -> Configuration properties -> C/C++ -> Advanced -> Disable specific warning add the value 4996.
if you use also the mfc and/or atl library (not my case) define before include mfc _AFX_SECURE_NO_DEPRECATE and before include atl _ATL_SECURE_NO_DEPRECATE.
i use this solution across visual studio 2003 and 2005.
p.s. if you use only visual studio the secure template overloads could be a good solution.
On Ubuntu the flatpak version seemed broken. I uninstalled it and downloaded the deb package right from Microsoft.
Applying inline-block
to the element that is to be centered and applying text-align:center
to the parent block did the trick for me.
Works even on <span>
tags.
I use extension methods to write things like that :

...
Here's the code :

if (withFlags && !Attribute.IsDefined(typeof(T), typeof(FlagsAttribute)))
throw new ArgumentException(string.Format("Type '{0}' doesn't have the 'Flags' attribute", typeof(T).FullName));
}

.loc
accept row and column selectors simultaneously (as do .ix/.iloc
FYI)
This is done in a single pass as well.

If your problem is not Maven related and you get the same NullPointerException running this in a browser (while running it from the IDE is fine), try this:
-> Netbeans -> Right-Click Project -> Properties -> Build -> Deployment -> Check "Request unrestricted access (Enable signing, self-signed)"
This is due to the @FXML Annotation needing permission to inject the value from the FXML markup (see http://docs.oracle.com/javafx/2/fxml_get_started/fxml_deployment.htm )
I was running my App on JDK8u31 and it would never run without the certificate in Chrome / Firefox / IE.
If you just want to pass a std::string
to a function that needs const char*
you can use
std::string str;
const char * c = str.c_str();
If you want to get a writable copy, like char *
, you can do that with this:
std::string str;
char * writable = new char[str.size() + 1];
std::copy(str.begin(), str.end(), writable);
writable[str.size()] = '\0'; // don't forget the terminating 0
// don't forget to free the string after finished using it
delete[] writable;
Edit: Notice that the above is not exception safe. If anything between the new
call and the delete
call throws, you will leak memory, as nothing will call delete
for you automatically. There are two immediate ways to solve this.
boost::scoped_array
will delete the memory for you upon going out of scope:
std::string str;
boost::scoped_array<char> writable(new char[str.size() + 1]);
std::copy(str.begin(), str.end(), writable.get());
writable[str.size()] = '\0'; // don't forget the terminating 0
// get the char* using writable.get()
// memory is automatically freed if the smart pointer goes
// out of scope
This is the standard way (does not require any external library). You use std::vector
, which completely manages the memory for you.
std::string str;
std::vector<char> writable(str.begin(), str.end());
writable.push_back('\0');
// get the char* using &writable[0] or &*writable.begin()
.PDB file is the short name of "Program Database". It contains the information about debug point for debugger and resources which are used or reference. Its generated when we build as debug mode. Its allow to application to debug at runtime.
The size is increase of .PDB file in debug mode. It is used when we are testing our application.
Good article of pdb file.

No net restart

Here's a solution using a negative lookahead (not supported in all regex engines):
^[a-zA-Z](((?!__)[a-zA-Z0-9_])*[a-zA-Z0-9])?$
Test that it works as expected:
import re
tests = [
('a', True),
('_', False),
('zz', True),
('a0', True),
('A_', False),
('a0_b', True),
('a__b', False),
('a_1_c', True),
]
regex = '^[a-zA-Z](((?!__)[a-zA-Z0-9_])*[a-zA-Z0-9])?$'
for test in tests:
is_match = re.match(regex, test[0]) is not None
if is_match != test[1]:
print "fail: " + test[0]
byte in Java is signed, so it has a range -2^7 to 2^7-1 - ie, -128 to 127. Since 132 is above 127, you end up wrapping around to 132-256=-124. That is, essentially 256 (2^8) is added or subtracted until it falls into range.
For more information, you may want to read up on two's complement.
I would just use
height: auto;
in your div. Yes, I know I'm a-little late but I figured this might help somebody like it would have helped me if it was here.
For GOOGLE, GOOGLEDOWN, GOOGLEUP i.e similar kind of value you can try below code
$("#HowYouKnow option:contains('GOOGLE')").each(function () {
if($(this).html()=='GOOGLE'){
$(this).attr('selected', 'selected');
}
});
In this way,number of loop iteration can be reduced and will work in all situation.
