You need to use ScriptManager.RegisterStartupScript for Ajax.
protected void ButtonPP_Click(object sender, EventArgs e) { if (radioBtnACO.SelectedIndex < 0) { string csname1 = "PopupScript"; var cstext1 = new StringBuilder(); cstext1.Append("alert('Please Select Criteria!')"); ScriptManager.RegisterStartupScript(this, GetType(), csname1, cstext1.ToString(), true); } }
You need the :not()
selector:
$('div[class^="first-"]:not(.first-bar)')
or, alternatively, the .not()
method:
$('div[class^="first-"]').not('.first-bar');
Here are clarified instruction combining Dawn Song's answer and Marmor's answer.
Drag a long Press Gesture Recognizer and drop it into your Table Cell. It will jump to the bottom of the list on the left.
Then connect the gesture recognizer the same way you would connect a button.
Add the code from Marmor in the the action handler
- (IBAction)handleLongPress:(UILongPressGestureRecognizer *)sender {
if (sender.state == UIGestureRecognizerStateBegan) {
CGPoint p = [sender locationInView:self.tableView];
NSIndexPath *indexPath = [self.tableView indexPathForRowAtPoint:p];
if (indexPath == nil) {
NSLog(@"long press on table view but not on a row");
} else {
UITableViewCell *cell = [self.tableView cellForRowAtIndexPath:indexPath];
if (cell.isHighlighted) {
NSLog(@"long press on table view at section %d row %d", indexPath.section, indexPath.row);
}
}
}
}
Here is example of using separated parallel
and for
here. In short it can be used for dynamic allocation of OpenMP thread-private arrays before executing for
cycle in several threads.
It is impossible to do the same initializing in parallel for
case.
UPD: In the question example there is no difference between single pragma and two pragmas. But in practice you can make more thread aware behavior with separated parallel and for directives. Some code for example:
#pragma omp parallel
{
double *data = (double*)malloc(...); // this data is thread private
#pragma omp for
for(1...100) // first parallelized cycle
{
}
#pragma omp single
{} // make some single thread processing
#pragma omp for // second parallelized cycle
for(1...100)
{
}
#pragma omp single
{} // make some single thread processing again
free(data); // free thread private data
}
You can use an array in the select() to define more columns and you can use the DB::raw() there with aliasing it to followers. Should look like this:
$query = DB::table('category_issue')
->select(array('issues.*', DB::raw('COUNT(issue_subscriptions.issue_id) as followers')))
->where('category_id', '=', 1)
->join('issues', 'category_issue.issue_id', '=', 'issues.id')
->left_join('issue_subscriptions', 'issues.id', '=', 'issue_subscriptions.issue_id')
->group_by('issues.id')
->order_by('followers', 'desc')
->get();
The NavigationController or TabBarController are the ones that need to provide the style. Here is how I solved: https://stackoverflow.com/a/39072526/242769
window.location
adds an item to your history in that you can (or should be able to) click "Back" and go back to the current page.
window.location.replace
replaces the current history item so you can't go back to it.
See window.location
:
assign(url)
: Load the document at the provided URL.
replace(url)
:Replace the current document with the one at the provided URL. The difference from theassign()
method is that after usingreplace()
the current page will not be saved in session history, meaning the user won't be able to use the Back button to navigate to it.
Oh and generally speaking:
window.location.href = url;
is favoured over:
window.location = url;
If you want to use a function form a package or module in python you have to import and reference them. For example normally you do the following to draw 5 points( [1,5],[2,4],[3,3],[4,2],[5,1]) in the space:
import matplotlib.pyplot
matplotlib.pyplot.plot([1,2,3,4,5],[5,4,3,2,1],"bx")
matplotlib.pyplot.show()
In your solution
from matplotlib import*
This imports the package matplotlib and "plot is not defined" means there is no plot function in matplotlib you can access directly, but instead if you import as
from matplotlib.pyplot import *
plot([1,2,3,4,5],[5,4,3,2,1],"bx")
show()
Now you can use any function in matplotlib.pyplot without referencing them with matplotlib.pyplot.
I would recommend you to name imports you have, in this case you can prevent disambiguation and future problems with the same function names. The last and clean version of above example looks like:
import matplotlib.pyplot as plt
plt.plot([1,2,3,4,5],[5,4,3,2,1],"bx")
plt.show()
I would just add that Java has Copy constructors...
Well, that's an ordinary constructor with an object of same type as argument.
If HEAD isn't set (i.e., you have no commits yet, but you don't want to just blow away .git
because you've already set up other repo config you want to keep), you can also do
git rm -rf --cached .
to unstage everything. This is effectively the same as sehe's solution, but avoids mucking with Git internals.
On Mac OS use
find -E packages -regex ".*\.(jpg|gif|png|jpeg)"
Fetch API
function load_home (e) {
(e || window.event).preventDefault();
fetch("http://www.yoursite.com/home.html" /*, options */)
.then((response) => response.text())
.then((html) => {
document.getElementById("content").innerHTML = html;
})
.catch((error) => {
console.warn(error);
});
}
XHR API
function load_home (e) {
(e || window.event).preventDefault();
var con = document.getElementById('content')
, xhr = new XMLHttpRequest();
xhr.onreadystatechange = function (e) {
if (xhr.readyState == 4 && xhr.status == 200) {
con.innerHTML = xhr.responseText;
}
}
xhr.open("GET", "http://www.yoursite.com/home.html", true);
xhr.setRequestHeader('Content-type', 'text/html');
xhr.send();
}
based on your constraints you should use ajax and make sure that your javascript is loaded before the markup that calls the load_home()
function
you have to add flag:
intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
or you will cause error with:
startActivity()
from outside of an Activity context requires the FLAG_ACTIVITY_NEW_TASK
A zombie is already dead, so you cannot kill it. To clean up a zombie, it must be waited on by its parent, so killing the parent should work to eliminate the zombie. (After the parent dies, the zombie will be inherited by pid 1, which will wait on it and clear its entry in the process table.) If your daemon is spawning children that become zombies, you have a bug. Your daemon should notice when its children die and wait
on them to determine their exit status.
An example of how you might send a signal to every process that is the parent of a zombie (note that this is extremely crude and might kill processes that you do not intend. I do not recommend using this sort of sledge hammer):
# Don't do this. Incredibly risky sledge hammer!
kill $(ps -A -ostat,ppid | awk '/[zZ]/ && !a[$2]++ {print $2}')

In a View, in my case a SurfaceView subclass, you can set the screen on always on. I wanted the screen to stay on while this view was still drawing stuff.
public class MyCoolSurfaceView extends SurfaceView {
@Override
protected void onAttachedToWindow (){
super.onAttachedToWindow();
this.setKeepScreenOn(true);
}
@Override
protected void onDetachedFromWindow(){
super.onDetachedFromWindow();
this.setKeepScreenOn(false);
}

cd $p
for f in [0-9][0-9][0-9][0-9]*.txt;do

)

The real problem is that the variable line always has a value. The test for "no matches found" is whether there is a match so the code "if line == None:" should be replaced with "else:"
My few cents. The forward-slash in the package name (laravel*/*laravel) is matter. If you put back-slash you will get package not found stability error.
The correct answer is, that, because the '%'
-sign is part of your search expression, it should be part of your VALUE, so whereever you SET @LastName
(be it from a programming language or from TSQL) you should set it to '%' + [userinput] + '%'
or, in your example:
DECLARE @LastName varchar(max)
SET @LastName = 'ning'
SELECT Employee WHERE LastName LIKE '%' + @LastName + '%'
You can use Array.sort
.
Here's an example:
var arr = [{
"updated_at": "2012-01-01T06:25:24Z",
"foo": "bar"
},
{
"updated_at": "2012-01-09T11:25:13Z",
"foo": "bar"
},
{
"updated_at": "2012-01-05T04:13:24Z",
"foo": "bar"
}
]
arr.sort(function(a, b) {
var keyA = new Date(a.updated_at),
keyB = new Date(b.updated_at);
// Compare the 2 dates
if (keyA < keyB) return -1;
if (keyA > keyB) return 1;
return 0;
});
console.log(arr);

I haven't tried specifically getting the VM settings, but there is a wealth of information in the JMX utilities specifically the MXBean utilities. This would be where I would start. Hopefully you find something there to help you.
The sun website has a bunch on the technology:
http://java.sun.com/javase/6/docs/technotes/guides/management/mxbeans.html
when it gets out from the using statement the Dispose
method will be called automatically closing the stream
try the below:
using (var ms = new MemoryStream())
{
var sw = new StreamWriter(ms);
sw.WriteLine("data");
sw.WriteLine("data 2");
ms.Position = 0;
using (var sr = new StreamReader(ms))
{
Console.WriteLine(sr.ReadToEnd());
}
}
On the most part, I'd say follow the pattern. I have deviated from it, but very rarely, and for specific reasons. In the case in point, the biggest issue I'd have is that I'd probably still use an Action<SomeObjectType>
, allowing me to add extra properties later, and to use the occasional 2-way property (think Handled
, or other feedback-events where the subscriber needs to to set a property on the event object). And once you've started down that line, you might as well use EventHandler<T>
for some T
.
or try NSString *string = [NSString stringWithFormat:@"%d", [NSNumber intValue], nil];
With \v
(as suggested in several comments)
:%s/\v(style|class)\=".{-}"//g
Probably you haven't injected $http

Since the latest language for Android Development is Kotlin. Here is, how we do it in Kotlin using Anonymous object.
spinnerName?.onItemSelectedListener = object : AdapterView.OnItemSelectedListener{
override fun onNothingSelected(parent: AdapterView<*>?) {
println("Nothing Selected")
}
override fun onItemSelected(parent: AdapterView<*>?, view: View?, position: Int, id: Long) {
val selectedString = yourList[position]
}
}
I have tried opening the .gitignore
file in my vscode, windows 10
. There you can see, some previously added ignore files (if any).
To create a new rule to ignore a file with (.js)
extension, append the extension of the file like this:
*.js
This will ignore all .js
files in your git
repository.
To exclude certain type of file from a particular directory, you can add this:
**/foo/*.js
This will ignore all .js files inside only /foo/ directory.
For a detailed learning you can visit: about git-ignore
You want to use single quotes:
if(c=='\0')
Double quotes (") are for strings, which are sequences of characters. Single quotes (') are for individual characters.
However, the end-of-line is represented by the newline character, which is '\n'.
Note that in both cases, the backslash is not part of the character, but just a way you represent special characters. Using backslashes you can represent various unprintable characters and also characters which would otherwise confuse the compiler.
You are logging sup
directly which is a string
console.log('sup')
Also you are using the wrong id
The template says #main_search
but you are using #searchBar
I suppose you are trying this out
$(function() {
var sup = $('#main_search').val('hi')
console.log(sup); // sup is a variable here
});
Here's something based on Jerub's "naive approach" (naive being his words, not mine!):
import string
ALLOWED = frozenset(string.ascii_letters + string.digits + '_' + '-')
def check(mystring):
return all(c in ALLOWED for c in mystring)
If ALLOWED
was a string then I think c in ALLOWED
would involve iterating over each character in the string until it found a match or reached the end. Which, to quote Joel Spolsky, is something of a Shlemiel the Painter algorithm.
But testing for existence in a set should be more efficient, or at least less dependent on the number of allowed characters. Certainly this approach is a little bit faster on my machine. It's clear and I think it performs plenty well enough for most cases (on my slow machine I can validate tens of thousands of short-ish strings in a fraction of a second). I like it.
ACTUALLY on my machine a regexp works out several times faster, and is just as simple as this (arguably simpler). So that probably is the best way forward.
Solution for Kotlin (Android 3.3, Kotlin 1.3.20)
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
supportActionBar!!.elevation = 0f
}
Here's a one-liner that removes all objects except for functions:
rm(list = setdiff(ls(), lsf.str()))
It uses setdiff
to find the subset of objects in the global environment (as returned by ls()
) that don't have mode function
(as returned by lsf.str()
)
The standard option grep -l
(that is a lowercase L) could do this.
From the Unix standard:
-l
(The letter ell.) Write only the names of files containing selected
lines to standard output. Pathnames are written once per file searched.
If the standard input is searched, a pathname of (standard input) will
be written, in the POSIX locale. In other locales, standard input may be
replaced by something more appropriate in those locales.
You also do not need -H
in this case.

In case you are like me, and cannot work out how to use "regular expression with capturing groups" for extract
, the following code replicates the extract(...)
line in Hadleys' answer:
df %>%
gather(question_number, value, starts_with("Q3.")) %>%
mutate(loop_number = str_sub(question_number,-2,-2), question_number = str_sub(question_number,1,4)) %>%
select(id, time, loop_number, question_number, value) %>%
spread(key = question_number, value = value)
The problem here is that the initial gather forms a key column that is actually a combination of two keys. I chose to use mutate
in my original solution in the comments to split this column into two columns with equivalent info, a loop_number
column and a question_number
column. spread
can then be used to transform the long form data, which are key value pairs (question_number, value)
to wide form data.
Also check that you are not using validation groups as that validation wouldnt fire if the validationgroup property was set and not explicitly called via
Page.Validate({Insert validation group name here});
You need to put the entire ternary expression in parenthesis. Unfortunately that means you can't use "@:", but you could do something like this:
@(deletedView ? "Deleted" : "Created by")
Razor currently supports a subset of C# expressions without using @() and unfortunately, ternary operators are not part of that set.
Into the Preferences > Setting - Default
You will have the next by default:
// Display file encoding in the status bar
"show_encoding": false
You could change it or like cdesmetz said set your user settings.
The reason for your fatal error is DOMDocument does not have a __toString() method and thus can not be echo'ed.
You're probably looking for
echo $dom->saveHTML();
I had countless issues doing this but finally came up with a solution that works.
Basically the code below is adding a click handler to the video but ignoring all the clicks on the lower part (0.82 is arbitrary but seems to work on all sizes).
$("video").click(function(e){
// get click position
var clickY = (e.pageY - $(this).offset().top);
var height = parseFloat( $(this).height() );
// avoids interference with controls
if(y > 0.82*height) return;
// toggles play / pause
this.paused ? this.play() : this.pause();
});
Try this:
var options = {
url: 'http://url',
timeout: 120000
}
request(options, function(err, resp, body) {});
Refer to request's documentation for other options.
To not deal with many 0s, use this variant:
Math.round(num * 1e2) / 1e2
For VB6:
You need to declare your C functions as __stdcall, otherwise you get "invalid calling convention" type errors. About other your questions:
can I take arguments by pointer/reference from the VB front-end?
Yes, use ByRef/ByVal modifiers.
Can the DLL call a theoretical function in the front-end?
Yes, use AddressOf statement. You need to pass function pointer to dll before.
Or have a function take a "function pointer" (I don't even know if that's possible) from VB and call it?)
Yes, use AddressOf statement.
update (more questions appeared :)):
to load it into VB, do I just do the usual method (what I would do to load winsock.ocx or some other runtime, but find my DLL instead) or do I put an API call into a module?
You need to decaler API function in VB6 code, like next:
Private Declare Function SHGetSpecialFolderLocation Lib "shell32" _
(ByVal hwndOwner As Long, _
ByVal nFolder As Long, _
ByRef pidl As Long) As Long
no that cannot work(not with real data):
String sql = "INSERT INTO course " +
"VALUES (course_code, course_desc, course_chair)";
stmt.executeUpdate(sql);
change it to:
String sql = "INSERT INTO course (course_code, course_desc, course_chair)" +
"VALUES (?, ?, ?)";
Create a PreparedStatment with that sql and insert the values with index:
PreparedStatement preparedStatement = conn.prepareStatement(sql);
preparedStatement.setString(1, "Test");
preparedStatement.setString(2, "Test2");
preparedStatement.setString(3, "Test3");
preparedStatement.executeUpdate();
Using Javascript, all you need is document.createElement
and setAttribute
.
var input = document.createElement("input");
input.setAttribute('type', 'text');
Then you can use appendChild
to append the created element to the desired parent element.
var parent = document.getElementById("parentDiv");
parent.appendChild(input);
When moving classes into specific packages like repository, controller, domain just the generic @SpringBootApplication
is not enough.
You will have to specify the base package for component scan
@ComponentScan("base_package")
For JPA
@EnableJpaRepositories(basePackages = "repository")
is also needed, so spring data will know where to look into for repository interfaces.
Otherwise... if
getenforce
returns
Enforcing
Then maybe you should call
setenforce 0
mount -o rw,remount /system
setenforce 1
This question is quite old, but I have made it that way (in TYPO3).
Firstly, I have made a own accessible css-class which I can choose on every content element manually.
Then, I have made a outer three column element with 11 columns (1 - 9 - 1), finally, I have modified the column width of the first and third column with CSS to 12.499999995%.
Use I
for "inline" to send the PDF to the browser, opposed to F
to save it as a file.
$pdf->Output('name.pdf', 'I');
Actually, you don't need all that stuff with opacity, visibility, <input>
styling, etc. Just take a look:
<a href="#">Just click me.</a>
<script type="text/javascript">
$("a").click(function() {
// creating input on-the-fly
var input = $(document.createElement("input"));
input.attr("type", "file");
// add onchange handler if you wish to get the file :)
input.trigger("click"); // opening dialog
return false; // avoiding navigation
});
</script>
Demo on jsFiddle. Tested in Chrome 30.0 and Firefox 24.0. Didn't work in Opera 12.16, however.
A javascript fix to apply the 'active' class to all labels that are parents of checked inputs:
$(':input:checked').parent('.btn').addClass('active');
insert right after
$('.btn').button();
in your MainActivity :
public class MainActivity extends AppCompatActivity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
if(ResourcesHelper.resources == null){
ResourcesHelper.resources = getResources();
}
}
}
ResourcesHelper :
public class ResourcesHelper {
public static Resources resources;
}
then use it everywhere
String s = ResourcesHelper.resources.getString(R.string.app_name);
Correct, when you drag a view controller object onto your storyboard in order to create a new scene, it doesn't automatically make the new class for you, too.
Having added a new view controller scene to your storyboard, you then have to:
Create a UIViewController
subclass. For example, go to your target's folder in the project navigator panel on the left and then control-click and choose "New File...". Choose a "Cocoa Touch Class":
And then select a unique name for the new view controller subclass:
Specify this new subclass as the base class for the scene you just added to the storyboard.
Now hook up any IBOutlet
and IBAction
references for this new scene with the new view controller subclass.
You can actually index directly into the Attributes collection (if you are using C# not VB):
foreach (XmlNode xNode in nodeListName)
{
XmlNode parent = xNode.ParentNode;
if (parent.Attributes != null
&& parent.Attributes["split"] != null)
{
parentSplit = parent.Attributes["split"].Value;
}
}
I guess you cant, this maybe a limitation or not included in the IE browser. I have tried your jsfiddle with IE6-8 and all of it doesn't show the scrollbar and not sure with IE9. While in FF and chrome the scrollbar is shown. I also want to see how to do it in IE if possible.
If you really want to show the scrollbar, you can add a fake scrollbar. If you are familiar with some of the js library which use in RIA. Like in jquery/dojo some of the select is editable, because it is a combination of textbox + select or it can also be a textbox + div.
As an example, see it here a JavaScript that make select like editable.

Note that I'm running on Linux so my TIMESTAMP
column actually gives me precision to six places i.e. microseconds. This would also be the case on most (all?) flavours of Unix. On Windows the limit is three places i.e. milliseconds. (Is this still true of the most modern flavours of Windows - citation needed).
As might be expected, the documentation covers this. Find out more.

(Those trailing zeroes could be a coincidence but they aren't.)
null and undefined are both are used to represent the absence of some value.
var a = null;
a is initialized and defined.
typeof(a)
//object
null is an object in JavaScript
Object.prototype.toString.call(a) // [object Object]
var b;
b is undefined and uninitialized
undefined object properties are also undefined. For example "x" is not defined on object c and if you try to access c.x, it will return undefined.
Generally we assign null to variables not undefined.
Read Only : Value can be changed through Ctor at runtime. But not through member Function
Constant : By default static. Value cannot be changed from anywhere ( Ctor, Function, runtime etc no-where)
Either use window.onload
this way
<script>
window.onload = function() {
// ...
}
</script>
or alternatively
<script>
window.onload = functionName;
</script>
(yes, without the parentheses)
Or just put the script at the very bottom of page, right before </body>
. At that point, all HTML DOM elements are ready to be accessed by document
functions.
<body>
...
<script>
functionName();
</script>
</body>
The best way is ssh -t user@server "sudo <scriptname>"
, for example ssh -t user@server "sudo reboot"
.
It will prompt for password for user first and then root(since we are running the script or command with root privilege.
I hope it helped and cleared your doubt.
This is probably too late, but I had a similar problem with dates that I wanted entered into cells from a text variable. Inevitably, it converted my variable text value to a date. What I finally had to do was concatentate a ' to the string variable and then put it in the cell like this:
prvt_rng_WrkSht.Cells(prvt_rng_WrkSht.Rows.Count, cnst_int_Col_Start_Date).Formula = "'" & _
param_cls_shift.Start_Date (string property of my class)
Following should work. I have verified. May be your problem is somewhere else.

If your margin is set on the body, then setting the background color of the html tag should color the margin area
html { background-color: black; }
body { margin:50px; background-color: white; }
Or as dmackerman suggestions, set a margin of 0, but a border of the size you want the margin to be and set the border-color
You can call max(vector, na.rm = TRUE)
. More generally, you can use the na.omit()
function.
Be careful of difference between 'c'
and "c"
'c'
is a char suitable for formatting with %c
"c"
is a char* pointing to a memory block with a length of 2 (with the null terminator).

I have published a proper plugin for the dropdown hover functionality, in which you can even define what happens when clicking on the dropdown-toggle
element:
https://github.com/istvan-ujjmeszaros/bootstrap-dropdown-hover
I had issues with all the previously existing solutions. The simple CSS ones are not using the .open
class on the .dropdown
, so there will be no feedback on the dropdown toggle element when the dropdown is visible.
The js ones are interfering with clicking on .dropdown-toggle
, so the dropdown shows up on hover, then hides it when clicking on an opened dropdown, and moving out the mouse will trigger the dropdown to show up again. Some of the js solutions are braking iOS compatibility, some plugins are not working on modern desktop browsers which are supporting the touch events.
That's why I made the Bootstrap Dropdown Hover plugin which prevents all these issues by using only the standard Bootstrap javascript API, without any hack.

Use insertMany
function to insert many documents. This sends only one operation to the server and Mongoose
validates all the documents before hitting the mongo server. By default Mongoose
inserts item in the order they exist in the array. If you are ok with not maintaining any order then set ordered:false
.
Important - Error handling:
When ordered:true
validation and error handling happens in a group means if one fails everything will fail.
When ordered:false
validation and error handling happens individually and operation will be continued. Error will be reported back in an array of errors.
The above are all excellent answers. I just wanted to add that when there are multiple characters to check against, an if-else might turn out better since you could instead write the following.
// switch on vowels, digits, punctuation, or consonants
char c; // assign some character to 'c'
if ("aeiouAEIOU".indexOf(c) != -1) {
// handle vowel case
} else if ("!@#$%,.".indexOf(c) != -1) {
// handle punctuation case
} else if ("0123456789".indexOf(c) != -1) {
// handle digit case
} else {
// handle consonant case, assuming other characters are not possible
}
Of course, if this gets any more complicated, I'd recommend a regex matcher.
A bit late, but to anyone who is wondering why they are getting the "Warning: Cannot use a scalar value as an array" message;
the reason is because somewhere you have first declared your variable with a normal integer or string and then later you are trying to turn it into an array.
hope that helps
Actually you can fix it with following steps -
cls.__dict__
{'isFilled':True}
or {'isFilled':False}
depending upon what you have set.del cls.__dict__['isFilled']
In this case, we delete the entry which overrides the method as mentioned by BrenBarn.
I had originally asked myself the question "Do I need a PDB file deployed to my customer's machine?", and after reading this post, decided to exclude the file.
Everything worked fine, until today, when I was trying to figure out why a message box containing an Exception.StackTrace
was missing the file and line number information - necessary for troubleshooting the exception. I re-read this post and found the key nugget of information: that although the PDB is not necessary for the app to run, it is necessary for the file and line numbers to be present in the StackTrace
string. I included the PDB file in the executable folder and now all is fine.
JQuery:
elemm.attr("onclick", "yourFunction(this)");
or:

Try Unlocker.
The Unlocker site has a nifty chart (scroll down after following the link) that shows a comparison to other tools. Obviously such comparisons are usually biased since they are typically written by the tool author, but the chart at least lists the alternatives so that you can try them for yourself.
If you want to update the user interface with activity result, you can't to use this.runOnUiThread(new Runnable() {}
Doing this the UI won't refresh with new value. Instead, you can do this:
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (resultCode == RESULT_CANCELED) {
return;
}
global_lat = data.getDoubleExtra("LATITUDE", 0);
global_lng = data.getDoubleExtra("LONGITUDE", 0);
new_latlng = true;
}
@Override
protected void onResume() {
super.onResume();
if(new_latlng)
{
PhysicalTagProperties.this.setLocation(global_lat, global_lng);
new_latlng=false;
}
}
This seems silly but works pretty well.
You should initialize variables to None and then check it:
var1 = None
if var1 is None:
var1 = 4
Which can be written in one line as:
var1 = 4 if var1 is None else var1
or using shortcut (but checking against None is recommended)
var1 = var1 or 4
alternatively if you will not have anything assigned to variable that variable name doesn't exist and hence using that later will raise NameError
, and you can also use that knowledge to do something like this
try:
var1
except NameError:
var1 = 4
but I would advise against that.

It's much easier (and faster) to get this information by only parsing the output of ver
:
@echo off
setlocal
for /f "tokens=4-5 delims=. " %%i in ('ver') do set VERSION=%%i.%%j
if "%version%" == "10.0" echo Windows 10
if "%version%" == "6.3" echo Windows 8.1
if "%version%" == "6.2" echo Windows 8.
if "%version%" == "6.1" echo Windows 7.
if "%version%" == "6.0" echo Windows Vista.
rem etc etc
endlocal
This table on MSDN documents which version number corresponds to which Windows product version (this is where you get the 6.1 means Windows 7 information from).
The only drawback of this technique is that it cannot distinguish between the equivalent server and consumer versions of Windows.
Purpose of view is displaying model. You should use controller to redirect request before creating model and passing it to view. Use Controller.RedirectToAction method for this.
If you are passing data to a DOM element from the server, you should set the data on the element:
<a id="foo" data-foo="bar" href="#">foo!</a>
The data can then be accessed using .data()
in jQuery:
console.log( $('#foo').data('foo') );
//outputs "bar"
However when you store data on a DOM node in jQuery using data, the variables are stored on the node object. This is to accommodate complex objects and references as storing the data on the node element as an attribute will only accommodate string values.
Continuing my example from above:$('#foo').data('foo', 'baz');
console.log( $('#foo').attr('data-foo') );
//outputs "bar" as the attribute was never changed
console.log( $('#foo').data('foo') );
//outputs "baz" as the value has been updated on the object
Also, the naming convention for data attributes has a bit of a hidden "gotcha":
HTML:<a id="bar" data-foo-bar-baz="fizz-buzz" href="#">fizz buzz!</a>
JS:
console.log( $('#bar').data('fooBarBaz') );
//outputs "fizz-buzz" as hyphens are automatically camelCase'd
The hyphenated key will still work:
HTML:<a id="bar" data-foo-bar-baz="fizz-buzz" href="#">fizz buzz!</a>
JS:
console.log( $('#bar').data('foo-bar-baz') );
//still outputs "fizz-buzz"
However the object returned by .data()
will not have the hyphenated key set:
$('#bar').data().fooBarBaz; //works
$('#bar').data()['fooBarBaz']; //works
$('#bar').data()['foo-bar-baz']; //does not work
It's for this reason I suggest avoiding the hyphenated key in javascript.
For HTML, keep using the hyphenated form. HTML attributes are supposed to get ASCII-lowercased automatically, so <div data-foobar></div>
, <DIV DATA-FOOBAR></DIV>
, and <dIv DaTa-FoObAr></DiV>
are supposed to be treated as identical, but for the best compatibility the lower case form should be preferred.
The .data()
method will also perform some basic auto-casting if the value matches a recognized pattern:
<a id="foo"
href="#"
data-str="bar"
data-bool="true"
data-num="15"
data-json='{"fizz":["buzz"]}'>foo!</a>
JS:
$('#foo').data('str'); //`"bar"`
$('#foo').data('bool'); //`true`
$('#foo').data('num'); //`15`
$('#foo').data('json'); //`{fizz:['buzz']}`
This auto-casting ability is very convenient for instantiating widgets & plugins:
$('.widget').each(function () {
$(this).widget($(this).data());
//-or-
$(this).widget($(this).data('widget'));
});
If you absolutely must have the original value as a string, then you'll need to use .attr()
:
<a id="foo" href="#" data-color="ABC123"></a>
<a id="bar" href="#" data-color="654321"></a>
JS:
$('#foo').data('color').length; //6
$('#bar').data('color').length; //undefined, length isn't a property of numbers
$('#foo').attr('data-color').length; //6
$('#bar').attr('data-color').length; //6
This was a contrived example. For storing color values, I used to use numeric hex notation (i.e. 0xABC123), but it's worth noting that hex was parsed incorrectly in jQuery versions before 1.7.2, and is no longer parsed into a Number
as of jQuery 1.8 rc 1.
jQuery 1.8 rc 1 changed the behavior of auto-casting. Before, any format that was a valid representation of a Number
would be cast to Number
. Now, values that are numeric are only auto-cast if their representation stays the same. This is best illustrated with an example.
<a id="foo"
href="#"
data-int="1000"
data-decimal="1000.00"
data-scientific="1e3"
data-hex="0x03e8">foo!</a>
JS:
// pre 1.8 post 1.8
$('#foo').data('int'); // 1000 1000
$('#foo').data('decimal'); // 1000 "1000.00"
$('#foo').data('scientific'); // 1000 "1e3"
$('#foo').data('hex'); // 1000 "0x03e8"
If you plan on using alternative numeric syntaxes to access numeric values, be sure to cast the value to a Number
first, such as with a unary +
operator.
+$('#foo').data('hex'); // 1000

You should use ResizeObserver. It is a browser-native solution that has a much better performance than to use the resize
event. In addition, it not only supports the event on the document
but also on arbitrary elements
.
var ro = new ResizeObserver( entries => { for (let entry of entries) { const cr = entry.contentRect; console.log('Element:', entry.target); console.log(`Element size: ${cr.width}px x ${cr.height}px`); console.log(`Element padding: ${cr.top}px ; ${cr.left}px`); } }); // Observe one or multiple elements ro.observe(someElement);
Currently, Firefox, Chrome, Safari, and Edge support it. For other (and older) browsers you have to use a polyfill.

While the solution of moving the contact_email
to parameters.yml
is easy, as proposed in other answers, that can easily clutter your parameters file if you deal with many bundles or if you deal with nested blocks of configuration.
FIRST APPROACH: Separated config block, getting it as a parameter
With an extension (more on extensions here) you can keep this easily "separated" into different blocks in the config.yml
and then inject that as a parameter gettable from the controller.
Inside your Extension class inside the DependencyInjection
directory write this:
class MyNiceProjectExtension extends Extension
{
public function load( array $configs, ContainerBuilder $container )
{
// The next 2 lines are pretty common to all Extension templates.
$configuration = new Configuration();
$processedConfig = $this->processConfiguration( $configuration, $configs );
// This is the KEY TO YOUR ANSWER
$container->setParameter( 'my_nice_project.contact_email', $processedConfig[ 'contact_email' ] );
// Other stuff like loading services.yml
}
Then in your config.yml, config_dev.yml and so you can set
my_nice_project:
contact_email: [email protected]
To be able to process that config.yml
inside your MyNiceBundleExtension
you'll also need a Configuration
class in the same namespace:
class Configuration implements ConfigurationInterface
{
public function getConfigTreeBuilder()
{
$treeBuilder = new TreeBuilder();
$rootNode = $treeBuilder->root( 'my_nice_project' );
$rootNode->children()->scalarNode( 'contact_email' )->end();
return $treeBuilder;
}
}
Then you can get the config from your controller, as you desired in your original question, but keeping the parameters.yml
clean, and setting it in the config.yml
in separated sections:
$recipient = $this->container->getParameter( 'my_nice_project.contact_email' );
SECOND APPROACH: Separated config block, injecting the config into a service
For readers looking for something similar but for getting the config from a service, there is even a nicer way that never clutters the "paramaters" common space and does even not need the container
to be passed to the service (passing the whole container is practice to avoid).
This trick above still "injects" into the parameters space your config.
Nevertheless, after loading your definition of the service, you could add a method-call like for example setConfig()
that injects that block only to the service.
For example, in the Extension class:
class MyNiceProjectExtension extends Extension
{
public function load( array $configs, ContainerBuilder $container )
{
$configuration = new Configuration();
$processedConfig = $this->processConfiguration( $configuration, $configs );
// Do not add a paramater now, just continue reading the services.
$loader = new YamlFileLoader( $container, new FileLocator( __DIR__ . '/../Resources/config' ) );
$loader->load( 'services.yml' );
// Once the services definition are read, get your service and add a method call to setConfig()
$sillyServiceDefintion = $container->getDefinition( 'my.niceproject.sillymanager' );
$sillyServiceDefintion->addMethodCall( 'setConfig', array( $processedConfig[ 'contact_email' ] ) );
}
}
Then in your services.yml
you define your service as usual, without any absolute change:
services:
my.niceproject.sillymanager:
class: My\NiceProjectBundle\Model\SillyManager
arguments: []
And then in your SillyManager
class, just add the method:
class SillyManager
{
private $contact_email;
public function setConfig( $newConfigContactEmail )
{
$this->contact_email = $newConfigContactEmail;
}
}
Note that this also works for arrays instead of scalar values! Imagine that you configure a rabbit queue and need host, user and password:
my_nice_project:
amqp:
host: 192.168.33.55
user: guest
password: guest
Of course you need to change your Tree, but then you can do:
$sillyServiceDefintion->addMethodCall( 'setConfig', array( $processedConfig[ 'amqp' ] ) );
and then in the service do:
class SillyManager
{
private $host;
private $user;
private $password;
public function setConfig( $config )
{
$this->host = $config[ 'host' ];
$this->user = $config[ 'user' ];
$this->password = $config[ 'password' ];
}
}
Hope this helps!

Because this answer is deprecated since iOS 10.0, a better answer would be:

}

Yes, there is a way to write to the event log you are looking for. You don't need to create a new source, just simply use the existent one, which often has the same name as the EventLog's name and also, in some cases like the event log Application, can be accessible without administrative privileges*.
*Other cases, where you cannot access it directly, are the Security EventLog, for example, which is only accessed by the operating system.
I used this code to write directly to the event log Application:
using (EventLog eventLog = new EventLog("Application"))
{
eventLog.Source = "Application";
eventLog.WriteEntry("Log message example", EventLogEntryType.Information, 101, 1);
}
As you can see, the EventLog source is the same as the EventLog's name. The reason of this can be found in Event Sources @ Windows Dev Center (I bolded the part which refers to source name):
Each log in the Eventlog key contains subkeys called event sources. The event source is the name of the software that logs the event. It is often the name of the application or the name of a subcomponent of the application if the application is large. You can add a maximum of 16,384 event sources to the registry.
Subversion 1.5 introduces sparse checkouts which may be something you might find useful. From the documentation:
... sparse directories (or shallow checkouts) ... allows you to easily check out a working copy—or a portion of a working copy—more shallowly than full recursion, with the freedom to bring in previously ignored files and subdirectories at a later time.
To fix the position use this :
div {
position: fixed;
left: 68%;
transform: translateX(-8%);
}
(copied from: source)
====================
1) there should not be any output (i.e. echo..
or HTML codes) before the header(.......);
command.
2) remove any white-space(or newline) before <?php
and after ?>
tags.
3) GOLDEN RULE! - check if that php file (and also, if you include
other files) have UTF8 without BOM encoding (and not just UTF-8). That is problem in many cases (because UTF8 encoded file has something special character in the start of php file, which your text-editor doesnt show)!!!!!!!!!!!
4) After header(...);
you must use exit;
5) always use 301 or 302 reference:
header("location: http://example.com", true, 301 ); exit;
6) Turn on error reporting, and find the error. Your error may be caused by a function that is not working. When you turn on error reporting, you should always fix top-most error first. For example, it might be "Warning: date_default_timezone_get(): It is not safe to rely on the system's timezone settings." - then farther on down you may see "headers not sent" error. After fixing top-most (1st) error, re-load your page. If you still have errors, then again fix the top-most error.
7) If none of above helps, use JAVSCRIPT redirection(however, strongly non-recommended method), may be the last chance in custom cases...:
echo "<script type='text/javascript'>window.top.location='http://website.com/';</script>"; exit;
Another option would be to use a procedure with output parameters - Using a Stored Procedure with Output Parameters
Otherwise than what wbdarby said, it even can happen when an object is fetched by giving the identifier of the object to a HQL. In the case of trying to modify the object fields and save it back into DB(modification could be insert, delete or update) over the same session, this error will appear. Try clearing the hibernate session before saving your modified object or create a brand new session.
Hope i helped ;-)

I have added this function to a library I created

-------------------------------
Well BenM stated, you need to detect the height of the viewport + the scroll position to match up with your top position. The function you are using is ok and does the job, though its a bit more complex than it needs to be.
If you don't use jQuery
then the script would be something like this:
function posY(elm) {
var test = elm, top = 0;
while(!!test && test.tagName.toLowerCase() !== "body") {
top += test.offsetTop;
test = test.offsetParent;
}
return top;
}
function viewPortHeight() {
var de = document.documentElement;
if(!!window.innerWidth)
{ return window.innerHeight; }
else if( de && !isNaN(de.clientHeight) )
{ return de.clientHeight; }
return 0;
}
function scrollY() {
if( window.pageYOffset ) { return window.pageYOffset; }
return Math.max(document.documentElement.scrollTop, document.body.scrollTop);
}
function checkvisible( elm ) {
var vpH = viewPortHeight(), // Viewport Height
st = scrollY(), // Scroll Top
y = posY(elm);
return (y > (vpH + st));
}
Using jQuery is a lot easier:
function checkVisible( elm, evalType ) {
evalType = evalType || "visible";
var vpH = $(window).height(), // Viewport Height
st = $(window).scrollTop(), // Scroll Top
y = $(elm).offset().top,
elementHeight = $(elm).height();
if (evalType === "visible") return ((y < (vpH + st)) && (y > (st - elementHeight)));
if (evalType === "above") return ((y < (vpH + st)));
}
This even offers a second parameter. With "visible" (or no second parameter) it strictly checks whether an element is on screen. If it is set to "above" it will return true when the element in question is on or above the screen.
See in action: http://jsfiddle.net/RJX5N/2/
I hope this answers your question.
-- IMPROVED VERSION--
This is a lot shorter and should do it as well:
function checkVisible(elm) {
var rect = elm.getBoundingClientRect();
var viewHeight = Math.max(document.documentElement.clientHeight, window.innerHeight);
return !(rect.bottom < 0 || rect.top - viewHeight >= 0);
}
with a fiddle to prove it: http://jsfiddle.net/t2L274ty/1/
And a version with threshold
and mode
included:
function checkVisible(elm, threshold, mode) {
threshold = threshold || 0;
mode = mode || 'visible';

cursor.fetchall()
and list(cursor)
are essentially the same. The different option is to not retrieve a list, and instead just loop over the bare cursor object:
for result in cursor:
This can be more efficient if the result set is large, as it doesn't have to fetch the entire result set and keep it all in memory; it can just incrementally get each item (or batch them in smaller batches).
Have you tried copying the schema file to the XML Schema Caching folder for VS? You can find the location of that folder by looking at VS Tools/Options/Test Editor/XML/Miscellaneous. Unfortunately, i don't know where's the schema file for the MS Enterprise Library 4.0.
Update: After installing MS Enterprise Library, it seems there's no .xsd file. However, there's a tool for editing the configuration - EntLibConfig.exe, which you can use to edit the configuration files. Also, if you add the proper config sections to your config file, VS should be able to parse the config file properly. (EntLibConfig will add these for you, or you can add them yourself). Here's an example for the loggingConfiguration section:
<configSections>
<section name="loggingConfiguration" type="Microsoft.Practices.EnterpriseLibrary.Logging.Configuration.LoggingSettings, Microsoft.Practices.EnterpriseLibrary.Logging, Version=4.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" />
</configSections>
You also need to add a reference to the appropriate assembly in your project.
To get the bottom 1000 you will want to order it by a column in descending order, and still take the top 1000.
SELECT TOP 1000 *
FROM [SomeTable]
ORDER BY MySortColumn DESC
If you care for it to be in the same order as before you can use a common table expression for that:
;WITH CTE AS (
SELECT TOP 1000 *
FROM [SomeTable]
ORDER BY MySortColumn DESC
)
SELECT *
FROM CTE
ORDER BY MySortColumn
Pass float to sleep, like sleep 0.1
You must close the project, hover over the project in the welcome screen, then press the delete button.
I came across this question having found requests in Firefox were being blocked with the message:
Reason: CORS request did not succeed
After pulling my hair out I found out that a newly installed Firefox extension, Privacy Badger, was blocking the requests.
If you come to this question after scratching your head, try checking to see what extensions you have installed to see if any of them are blocking requests.
See Reason: CORS request did not succeed on MDN for details.
Try
xargs -n2 printf "%-20s%s\n"
or even

There is several escaping options with same result:
body { width: ~"calc(100% - 250px - 1.5em)"; }
body { width: calc(~"100% - 250px - 1.5em"); }
body { width: calc(100% ~"-" 250px ~"-" 1.5em); }
if you just want the number of occurences then you can do this, $ grep -c "string_to_count" file_name
I have implemented this way and it works.It is much easier than all that is reported.
We have two activities : one is the main and another is the secondary.
In secondary activity, which is where we want to end the main activity , define the following variable:
public static Activity ACTIVIDAD;
And then the following method:
public static void enlaceActividadPrincipal(Activity actividad)
{
tuActividad.ACTIVIDAD=actividad;
}
Then, in your main activity from the onCreate
method , you make the call:
actividadSecundaria.enlaceActividadPrincipal(this);
Now, you're in control. Now, from your secondary activity, you can complete the main activity. Finish calling the function, like this:
ACTIVIDAD.finish();
One can simply use
INSERT INTO MY_TABLE(MY_TIMESTAMP_FIELD)
VALUES (TIMESTAMP '2019-02-15 13:22:11.871+02:00');
This way you won't have to worry about date format string, just use default timestamp format.
Works with Oracle 11, have no idea if it does for earlier Oracle versions.
It's used for converting arbitrary binary data to ASCII text.
For example, e-mail attachments are sent this way.
This is an example of how to post string and file stream with HTTPClient using MultipartFormDataContent. The Content-Disposition and Content-Type need to be specified for each HTTPContent:
Here's my example. Hope it helps:
private static void Upload()
{
using (var client = new HttpClient())
{
client.DefaultRequestHeaders.Add("User-Agent", "CBS Brightcove API Service");
using (var content = new MultipartFormDataContent())
{
var path = @"C:\B2BAssetRoot\files\596086\596086.1.mp4";
string assetName = Path.GetFileName(path);
var request = new HTTPBrightCoveRequest()
{
Method = "create_video",
Parameters = new Params()
{
CreateMultipleRenditions = "true",
EncodeTo = EncodeTo.Mp4.ToString().ToUpper(),
Token = "x8sLalfXacgn-4CzhTBm7uaCxVAPjvKqTf1oXpwLVYYoCkejZUsYtg..",
Video = new Video()
{
Name = assetName,
ReferenceId = Guid.NewGuid().ToString(),
ShortDescription = assetName
}
}
};
//Content-Disposition: form-data; name="json"
var stringContent = new StringContent(JsonConvert.SerializeObject(request));
stringContent.Headers.Add("Content-Disposition", "form-data; name=\"json\"");
content.Add(stringContent, "json");
FileStream fs = File.OpenRead(path);
var streamContent = new StreamContent(fs);
streamContent.Headers.Add("Content-Type", "application/octet-stream");
//Content-Disposition: form-data; name="file"; filename="C:\B2BAssetRoot\files\596090\596090.1.mp4";
streamContent.Headers.Add("Content-Disposition", "form-data; name=\"file\"; filename=\"" + Path.GetFileName(path) + "\"");
content.Add(streamContent, "file", Path.GetFileName(path));
//content.Headers.ContentDisposition = new ContentDispositionHeaderValue("attachment");
Task<HttpResponseMessage> message = client.PostAsync("http://api.brightcove.com/services/post", content);
var input = message.Result.Content.ReadAsStringAsync();
Console.WriteLine(input.Result);
Console.Read();
}
}
}
I confirm like the comment from JohnH, never use column types in the your object names! It's confusing. And use brackets if possible.
Try this:
ALTER TABLE [TableName]
ADD DEFAULT (getutcdate()) FOR [Date];
See explanation here.
The Callable interface is similar to Runnable, in that both are designed for classes whose instances are potentially executed by another thread. A Runnable, however, does not return a result and cannot throw a checked exception.
- (void)moveToPage {
NSUInteger pageIndex = ((ContentViewController *) [self.pageViewController.viewControllers objectAtIndex:0]).pageIndex;
pageIndex++;
ContentViewController *viewController = [self viewControllerAtIndex:pageIndex];
if (viewController == nil) {
return;
}
[self.pageViewController setViewControllers:@[viewController] direction:UIPageViewControllerNavigationDirectionForward animated:YES completion:nil];
}
//now call this method
[self moveToPage];
I hope it works :)

The reason of crush — index 0 wasn't set. Simple $array = $array + array(null)
did the trick. Or you should check whether array element on index 0 is set via isset($array[0])
. The second variant is the best approach for me.
Install the CSS Usage add-on for Firebug and run it on that page. It will tell you which styles are being used and not used by that page.
This might be easier to explain with a sample dataset.
Create Sample Data
Let's assume we have a single column of Timestamps, date
and another column we would like to perform an aggregation on, a
.
df = pd.DataFrame({'date':pd.DatetimeIndex(['2012-1-1', '2012-6-1', '2015-1-1', '2015-2-1', '2015-3-1']),
'a':[9,5,1,2,3]}, columns=['date', 'a'])
df
date a
0 2012-01-01 9
1 2012-06-01 5
2 2015-01-01 1
3 2015-02-01 2
4 2015-03-01 3
There are several ways to group by year
year
propertydate
in index and use anonymous function to access yearresample
method.dt
accessor with year
propertyWhen you have a column (and not an index) of pandas Timestamps, you can access many more extra properties and methods with the dt
accessor. For instance:
df['date'].dt.year
0 2012
1 2012
2 2015
3 2015
4 2015
Name: date, dtype: int64
We can use this to form our groups and calculate some aggregations on a particular column:
df.groupby(df['date'].dt.year)['a'].agg(['sum', 'mean', 'max'])
sum mean max
date
2012 14 7 9
2015 6 2 3
If you set the date column as the index, it becomes a DateTimeIndex with the same properties and methods as the dt
accessor gives normal columns
df1 = df.set_index('date')
df1.index.year
Int64Index([2012, 2012, 2015, 2015, 2015], dtype='int64', name='date')
Interestingly, when using the groupby method, you can pass it a function. This function will be implicitly passed the DataFrame's index. So, we can get the same result from above with the following:
df1.groupby(lambda x: x.year)['a'].agg(['sum', 'mean', 'max'])
sum mean max
2012 14 7 9
2015 6 2 3
resample
methodIf your date column is not in the index, you must specify the column with the on
parameter. You also need to specify the offset alias as a string.
df.resample('AS', on='date')['a'].agg(['sum', 'mean', 'max'])
sum mean max
date
2012-01-01 14.0 7.0 9.0
2013-01-01 NaN NaN NaN
2014-01-01 NaN NaN NaN
2015-01-01 6.0 2.0 3.0
You can also convert the date column to a pandas Period object. We must pass in the offset alias as a string to determine the length of the Period.
df['date'].dt.to_period('A')
0 2012
1 2012
2 2015
3 2015
4 2015
Name: date, dtype: object
We can then use this as a group
df.groupby(df['date'].dt.to_period('Y'))['a'].agg(['sum', 'mean', 'max'])
sum mean max
2012 14 7 9
2015 6 2 3
For ajax select2 multiple select dropdown i did like this;
//preset element values
//topics is an array of format [{"id":"","text":""}, .....]
$(id).val(topics);
setTimeout(function(){
ajaxTopicDropdown(id,
2,location.origin+"/api for gettings topics/",
"Pick a topic", true, 5);
},1);
// ajaxtopicDropdown is dry fucntion to get topics for diffrent element and url
Something like this should work.

A general answer involves using a Manager
object. Adapted from the docs:
from multiprocessing import Process, Manager
def f(d):
d[1] += '1'
d['2'] += 2
if __name__ == '__main__':
manager = Manager()
d = manager.dict()
d[1] = '1'
d['2'] = 2
p1 = Process(target=f, args=(d,))
p2 = Process(target=f, args=(d,))
p1.start()
p2.start()
p1.join()
p2.join()
print d
Output:
$ python mul.py
{1: '111', '2': 6}
You need to have a height in the div <div style="overflow:hidden">
else it doesnt know what 100%
is.
As soon as there is only method Long.valueOf(long)
, cast from int
to long
will be done implicitly in case of using Long.valueOf(intValue)
.
The more clear way to do this is
Integer.valueOf(intValue).longValue()
This is the official documentation about hiding the Status Bar on Android 4.0 and lower and on Android 4.1 and higher
Please, take a look at it:
https://developer.android.com/training/system-ui/status.html
First connect the Height constraint in to our viewcontroller for creating IBOutlet like the below code shown
@IBOutlet weak var select_dateHeight: NSLayoutConstraint!
then put the below code in view did load or inside any actions
self.select_dateHeight.constant = 0 // we can change the height value
if it is inside a button click
@IBAction func Feedback_button(_ sender: Any) {
self.select_dateHeight.constant = 0
}
This worked very well for me.
REVERSE(SUBSTRING(REVERSE([field]), CHARINDEX(REVERSE('[expr]'), REVERSE([field])) + DATALENGTH('[expr]'), DATALENGTH([field])))
For me it was because I'd added an entry to bind the site in IISExpress to a specific IP address, and my IP address had changed. I got a clue from the event log.

Use df.count()
to get the number of rows.
You could also get all relevant details from performance_schema:
SELECT
OBJECT_SCHEMA
,OBJECT_NAME
,GROUP_CONCAT(DISTINCT EXTERNAL_LOCK)
FROM performance_schema.table_handles
WHERE EXTERNAL_LOCK IS NOT NULL
GROUP BY
OBJECT_SCHEMA
,OBJECT_NAME
This works similar as
show open tables WHERE In_use > 0
You have to encode your email as multipart mime and then you can attach emails as attachments basically. You reference them by cid in the email.
Alternatively you could not attach them to the email and use URLs directly but most mail programs will block this as spammers use the trick to detect the liveness of email addresses.
You don't say what language but here is one example.
Try to change #include <gl/glut.h>
to #include "gl/glut.h"
in Visual Studio 2013.
Regarding the difference between an object
and an instance
, I do not think there is any consensus.
It looks to me like people change it pretty much interchangeably, in papers, blog posts, books or conversations.
As for me, the way I see it is, an object is a generic and alive entity in the memory, specified by the language it is used in. Just like the Object
class in Java
. We do not much care its type, or anything else associated with it, whether it is managed by a container or not.
An instance
is an object
but associated with a type, as in this method accepts Foo instances
, or you can not put Animal instances in an instance of
a List of Vehicles
.
object
s for example have locks
associated with them, not instance
s, whereas instance
s have methods. objects
are garbage collected, not instance
s.
But as I said, this is only how I see it, and I do not think there is any organisation we can refer to for a standard definition between them and everyone will pretty much have their slightly different understanding / definitions (of course within limits).
Here's my take if you want to try using multiprocesses to process each row of numpy array,
from multiprocessing import Pool
import numpy as np
def my_function(x):
pass # do something and return something
if __name__ == '__main__':
X = np.arange(6).reshape((3,2))
pool = Pool(processes = 4)
results = pool.map(my_function, map(lambda x: x, X))
pool.close()
pool.join()
pool.map take in a function and an iterable.
I used 'map' function to create an iterator over each rows of the array.
Maybe there's a better to create the iterable though.
I had an issue with the downscaleImage()
function posted above by @daniel-allen-langdon in that the image.width
and image.height
properties are not available immediately because the image load is asynchronous.
Please see updated TypeScript example below that takes this into account, uses async
functions, and resizes the image based on the longest dimension rather than just the width
function getImage(dataUrl: string): Promise<HTMLImageElement>
{
return new Promise((resolve, reject) => {
const image = new Image();
image.src = dataUrl;
image.onload = () => {
resolve(image);
};
image.onerror = (el: any, err: ErrorEvent) => {
reject(err.error);
};
});
}
export async function downscaleImage(
dataUrl: string,
imageType: string, // e.g. 'image/jpeg'
resolution: number, // max width/height in pixels
quality: number // e.g. 0.9 = 90% quality
): Promise<string> {
// Create a temporary image so that we can compute the height of the image.
const image = await getImage(dataUrl);
const oldWidth = image.naturalWidth;
const oldHeight = image.naturalHeight;
console.log('dims', oldWidth, oldHeight);
const longestDimension = oldWidth > oldHeight ? 'width' : 'height';
const currentRes = longestDimension == 'width' ? oldWidth : oldHeight;
console.log('longest dim', longestDimension, currentRes);
if (currentRes > resolution) {
console.log('need to resize...');
// Calculate new dimensions
const newSize = longestDimension == 'width'
? Math.floor(oldHeight / oldWidth * resolution)
: Math.floor(oldWidth / oldHeight * resolution);
const newWidth = longestDimension == 'width' ? resolution : newSize;
const newHeight = longestDimension == 'height' ? resolution : newSize;
console.log('new width / height', newWidth, newHeight);
// Create a temporary canvas to draw the downscaled image on.
const canvas = document.createElement('canvas');
canvas.width = newWidth;
canvas.height = newHeight;
// Draw the downscaled image on the canvas and return the new data URL.
const ctx = canvas.getContext('2d')!;
ctx.drawImage(image, 0, 0, newWidth, newHeight);
const newDataUrl = canvas.toDataURL(imageType, quality);
return newDataUrl;
}
else {
return dataUrl;
}
}
Although this is an old question, there are several of us still struggle to find an answer. At least I did. Please don't follow all the lengthy solutions. You could simply login to your mysql as root without providing any password (provided it is a fresh installation or you haven't changed the password since your installation) by adding sudo before your mysql command.
$sudo mysql -uroot -p

This is because mysql changed the security model in one of the latest versions.

clearfix
is the same as overflow:hidden
. Both clear floated children of the parent, but clearfix
will not cut off the element which overflow to it's parent
.
It also works in IE8 & above.
There is no need to define "."

.clr:after {
clear: both;
content: "";
display: block;
}

Setting the top and left properties to negative values might not be a good workaround if your problem is simply that you're in quirks mode. This can happen if the page is missing a <!DOCTYPE>
declaration, causing it to be rendered in quirks mode in IE8. In IE8 Developer Tools, make sure that "Quirks Mode" is not selected under "Document Mode". If it is selected, you may need to add the appropriate <!DOCTYPE>
declaration.
Would it be cheating to use the /
operator "behind the scenes" by using eval
and string concatenation?
For example, in Javacript, you can do
function div3 (n) {
var div = String.fromCharCode(47);
return eval([n, div, 3].join(""));
}
If you are using Git For Windows then it is located at
C:\Program Files\Git\mingw64\libexec\git-core
It is nice to have in mind that Git For Windows offers Git CMD, a command prompt with the PATH already set. Git CMD is available as a shortcut in
Start Menu > Programs > Git
among other options.
Maybe git mv
has changed since these answers were posted, so I will update briefly. In my view, git mv
is not accurately described as short hand for:
# not accurate: #
mv oldname newname
git add newname
git rm oldname
I use git mv frequently for two reasons that have not been described in previous answers:
Moving large directory structures, where I have mixed content of both tracked and untracked files. Both tracked and untracked files will move, and retain their tracking/untracking status
Moving files and directories that are large, I have always assumed that git mv
will reduce the size of the repository DB history size. This is because moving/renaming a file is indexation/reference delta. I have not verified this assumption, but it seems logical.
This is more explicit than necessary, but does what you want.
with open("file.txt") as file_in:
lines = []

lines.append(line)
read
does not export the variable (which is a good thing most of the time). Here's an alternative which can be exported in one command, can preserve or discard linefeeds, and allows mixing of quoting-styles as needed. Works for bash and zsh.
oneLine=$(printf %s \
a \
" b " \
$'\tc\t' \
'd ' \
)
multiLine=$(printf '%s\n' \
a \
" b " \
$'\tc\t' \
'd ' \
)
I admit the need for quoting makes this ugly for SQL, but it answers the (more generally expressed) question in the title.
I use it like this
export LS_COLORS=$(printf %s \
':*rc=36:*.ini=36:*.inf=36:*.cfg=36:*~=33:*.bak=33:*$=33' \
...

and .zshrc
.
Use JSON classes for parsing e.g

JSONObject oneObject = mainObject.getJSONObject("1");
String id = oneObject.getString("id");

A nasty way is to do it with reflection. Something like this worked for me.
public static <T extends Cloneable> List<T> deepCloneList(List<T> original) {
if (original == null || original.size() < 1) {
return new ArrayList<>();
}
try {
int originalSize = original.size();
Method cloneMethod = original.get(0).getClass().getDeclaredMethod("clone");
List<T> clonedList = new ArrayList<>();
// noinspection ForLoopReplaceableByForEach
for (int i = 0; i < originalSize; i++) {
// noinspection unchecked
clonedList.add((T) cloneMethod.invoke(original.get(i)));
}
return clonedList;
} catch (NoSuchMethodException | InvocationTargetException | IllegalAccessException e) {
System.err.println("Couldn't clone list due to " + e.getMessage());
return new ArrayList<>();
}
}
This can be done using HTML5, but will only work in browsers that support it. Here's an example.
Bear in mind you'll need an alternative method for browsers that don't support this. I've had a lot of success with this plugin, which takes a lot of the work out of your hands.
In PowerShell v5.1 this is slightly different compared to v5. According to MS documentation, it has to have a -Path
parameter to specify the archive file path.
Expand-Archive -Path Draft.Zip -DestinationPath C:\Reference
Or else, this can be an actual path:
Expand-Archive -Path c:\Download\Draft.Zip -DestinationPath C:\Reference
You can also use this way for getting random number between 1 and 100 as:
SecureRandom src=new SecureRandom();
int random=1 + src.nextInt(100);

Python's print
function adds a newline character to its input. If you give it no input it will just print a newline character
print()
Will print an empty line. If you want to have an extra line after some text you're printing, you can a newline to your text
my_str = "hello world"
print(my_str + "\n")
If you're doing this a lot, you can also tell print
to add 2 newlines instead of just one by changing the end=
parameter (by default end="\n"
)
print("hello world", end="\n\n")
But you probably don't need this last method, the two before are much clearer.

will give you the referrer page's URL if there exists any. If users use a bookmark or directly visit your site by manually typing in the URL, http_referer will be empty. Also if the users are posting to your page programatically (CURL) then they're not obliged to set the http_referer as well. You're missing all _
, is that a typo?
OIDs basically give you a built-in id for every row, contained in a system column (as opposed to a user-space column). That's handy for tables where you don't have a primary key, have duplicate rows, etc. For example, if you have a table with two identical rows, and you want to delete the oldest of the two, you could do that using the oid column.
OIDs are implemented using 4-byte unsigned integers. They are not unique–OID counter will wrap around at 2³²-1. OID are also used to identify data types (see /usr/include/postgresql/server/catalog/pg_type_d.h
).
In my experience, the feature is generally unused in most postgres-backed applications (probably in part because they're non-standard), and their use is essentially deprecated:
In PostgreSQL 8.1 default_with_oids is off by default; in prior versions of PostgreSQL, it was on by default.
The use of OIDs in user tables is considered deprecated, so most installations should leave this variable disabled. Applications that require OIDs for a particular table should specify WITH OIDS when creating the table. This variable can be enabled for compatibility with old applications that do not follow this behavior.
I used :
from pil import Image
instead of
from PIL import Image
and it worked for me fine

You don't need to iterate through the DataGrid
rows, you can achieve your goal with a more simple solution.
In order to match your row you can iterate through you collection that was bound to your DataGrid.ItemsSource
property then assign this item to you DataGrid.SelectedItem
property programmatically, alternatively you can add it to your DataGrid.SelectedItems
collection if you want to allow the user to select more than one row. See the code below:
<Window x:Class="ProgGridSelection.MainWindow"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
Title="MainWindow" Height="350" Width="525" Loaded="OnWindowLoaded">
<StackPanel>
<DataGrid Name="empDataGrid" ItemsSource="{Binding}" Height="200"/>
<TextBox Name="empNameTextBox"/>
<Button Content="Click" Click="OnSelectionButtonClick" />
</StackPanel>
public partial class MainWindow : Window
{
public class Employee
{
public string Code { get; set; }
public string Name { get; set; }
}
private ObservableCollection<Employee> _empCollection;
public MainWindow()
{
InitializeComponent();
}
private void OnWindowLoaded(object sender, RoutedEventArgs e)
{
// Generate test data
_empCollection =
new ObservableCollection<Employee>
{
new Employee {Code = "E001", Name = "Mohammed A. Fadil"},
new Employee {Code = "E013", Name = "Ahmed Yousif"},
new Employee {Code = "E431", Name = "Jasmin Kamal"},
};
/* Set the Window.DataContext, alternatively you can set your
* DataGrid DataContext property to the employees collection.
* on the other hand, you you have to bind your DataGrid
* DataContext property to the DataContext (see the XAML code)
*/
DataContext = _empCollection;
}
private void OnSelectionButtonClick(object sender, RoutedEventArgs e)
{
/* select the employee that his name matches the
* name on the TextBox
*/
var emp = (from i in _empCollection
where i.Name == empNameTextBox.Text.Trim()
select i).FirstOrDefault();
/* Now, to set the selected item on the DataGrid you just need
* assign the matched employee to your DataGrid SeletedItem
* property, alternatively you can add it to your DataGrid
* SelectedItems collection if you want to allow the user
* to select more than one row, e.g.:
* empDataGrid.SelectedItems.Add(emp);
*/
if (emp != null)
empDataGrid.SelectedItem = emp;
}
}
Why do you think your solution is "clunky"? Personally I would prefer one constructor with default values over multiple overloaded constructors in situations like yours (Python does not support method overloading anyway):
def __init__(self, num_holes=None):
if num_holes is None:
# Construct a gouda
else:
# custom cheese
# common initialization
For really complex cases with lots of different constructors, it might be cleaner to use different factory functions instead:
@classmethod
def create_gouda(cls):
c = Cheese()
# ...
return c
@classmethod
def create_cheddar(cls):
# ...
In your cheese example you might want to use a Gouda subclass of Cheese though...
I got this working.

Only checked
and checked="checked"
are valid. Your other options depend on error recovery in browsers.
checked="yes"
and checked="true"
are particularly bad as they imply that checked="no"
and checked="false"
will set the default state to be unchecked … which they will not.
You can get the spark version by using the following command:

I don't believe there's anything built-in for this. It's made tricky by the fact that it's rare for a single line to change several times without the rest of the file changing substantially too, so you'll tend to end up with the line numbers changing a lot.
If you're lucky enough that the line always has some identifying characteristic, e.g. an assignment to a variable whose name never changed, you could use the regex choice for git blame -L
. For example:
git blame -L '/variable_name *= */',+1
But this only finds the first match for that regex, so if you don't have a good way of matching the line, it's not too helpful.
You could hack something up, I suppose. I don't have time to write out code just now, but... something along these lines. Run git blame -n -L $n,$n $file
. The first field is the previous commit touched, and the second field is the line number in that commit, since it could've changed. Grab those, and run git blame -n $n,$n $commit^ $file
, i.e. the same thing starting from the commit before the last time the file was changed.
(Note that this will fail you if the last commit that changed the line was a merge commit. The primary way this could happen if the line was changed as part of a merge conflict resolution.)
Edit: I happened across this mailing list post from March 2011 today, which mentions that tig
and git gui
have a feature that will help you do this. It looks like the feature has been considered, but not finished, for git itself.
In the recent go versions from 1.14 onwards, we have to do go mod vendor
before building or running, since by default go appends -mod=vendor
to the go commands.
So after doing go mod vendor
, if we try to build, we won't face this issue.
Go to Terminal -> Preferences -> Advanced (Tab)
go down to International

When working on an important code update, if you really need an intermediate safepoint you might just do:
git commit -am'.'
or shorter:
git commit -am.
I found an a bit different solution of my problem regarding this context. Thought worth sharing.
Most of the example create readStreams
from file. But in my case readStream
has to be created from JSON
string coming from a message pool.
var jsonStream = through2.obj(function(chunk, encoding, callback) {
this.push(JSON.stringify(chunk, null, 4) + '\n');
callback();
});
// message.value --> value/text to write in write.txt
jsonStream.write(JSON.parse(message.value));
var writeStream = sftp.createWriteStream("/path/to/write/write.txt");
//"close" event didn't work for me!
writeStream.on( 'close', function () {
console.log( "- done!" );
sftp.end();
}
);
//"finish" event didn't work for me either!
writeStream.on( 'close', function () {
console.log( "- done!"
sftp.end();
}
);
// finally this worked for me!
jsonStream.on('data', function(data) {
var toString = Object.prototype.toString.call(data);
console.log('type of data:', toString);
console.log( "- file transferred" );
});
jsonStream.pipe( writeStream );
It normally represents a parameter to be supplied by client.

supplementing @falsetru's answer : run id in the terminal to get your user_id and group_id
Go the directory/partition where you are facing the challenge. Open terminal, type id then press enter. This will show you your user_id and group_id
then type
chown -R user-id:group-id .
Replace user-id and group-id
. at the end indicates current partition / repository
// chown -R 1001:1001 . (that was my case)
git apply --reject --whitespace=fix mychanges.patch
worked for me.
The --reject
option will instruct git to not fail if it cannot determine how to apply a patch, but instead to apply indivdual hunks it can apply and create reject files (.rej
) for hunks it cannot apply. Wiggle can "apply [these] rejected patches and perform word-wise diffs".
Additionally, --whitespace=fix
will warn about whitespace errors and try to fix them, rather than refusing to apply an otherwise applicable hunk.
Both options together make the application of a patch more robust against failure, but they require additional attention with respect to the result.
For the whole documentation, see https://git-scm.com/docs/git-apply.
In addition to cookies and localStorage
, there's at least one other place you can store "semi-persistent" client data: window.name
. Any string value you assign to window.name
will stay there until the window is closed.
To test it out, just open the console and type window.name = "foo"
, then refresh the page and type window.name
; it should respond with foo
.
This is a bit of a hack, but if you don't want cookies filled with unnecessary data being sent to the server with every request, and if you can't use localStorage
for whatever reason (legacy clients), it may be an option to consider.
window.name
has another interesting property: it's visible to windows served from other domains; it's not subject to the same-origin policy like nearly every other property of window
. So, in addition to storing "semi-persistent" data there while the user navigates or refreshes the page, you can also use it for CORS-free cross-domain communication.
Note that window.name
can only store strings, but with the wide availability of JSON
, this shouldn't be much of an issue even for complex data.
There are three reasons why you shouldn't use for..in
to iterate over array elements:
for..in
will loop over all own and inherited properties of the array object which aren't DontEnum
; that means if someone adds properties to the specific array object (there are valid reasons for this - I've done so myself) or changed Array.prototype
(which is considered bad practice in code which is supposed to work well with other scripts), these properties will be iterated over as well; inherited properties can be excluded by checking hasOwnProperty()
, but that won't help you with properties set in the array object itself
for..in
isn't guaranteed to preserve element ordering
it's slow because you have to walk all properties of the array object and its whole prototype chain and will still only get the property's name, ie to get the value, an additional lookup will be required
this is what i did
first execute create database x
. x is the name of your old database eg the name of the mdf.
Then open sql sever configration and stop the sql sever.
There after browse to the location of your new created database it should be under program file, in my case is
C:\Program Files\Microsoft SQL Server\MSSQL14.MSSQL\MSSQL\DATA
and repleace the new created mdf and Idf with the old files/database.
then simply restart the sql server and walla :)
If you are using javascript in HTML, you should include file1.js
and file2.js
inside your html:
<script src="path_to/file1.js"></script>
<script src="path_to/file2.js"></script>
Note, file1
should come first before file2
.
In v2.0 of the Graph API, calling /me/friends
returns the person's friends who also use the app.
In addition, in v2.0, you must request the user_friends
permission from each user. user_friends
is no longer included by default in every login. Each user must grant the user_friends
permission in order to appear in the response to /me/friends
. See the Facebook upgrade guide for more detailed information, or review the summary below.
The /me/friendlists
endpoint and user_friendlists
permission are not what you're after. This endpoint does not return the users friends - its lets you access the lists a person has made to organize their friends. It does not return the friends in each of these lists. This API and permission is useful to allow you to render a custom privacy selector when giving people the opportunity to publish back to Facebook.
If you want to access a list of non-app-using friends, there are two options:
If you want to let your people tag their friends in stories that they publish to Facebook using your App, you can use the /me/taggable_friends
API. Use of this endpoint requires review by Facebook and should only be used for the case where you're rendering a list of friends in order to let the user tag them in a post.
If your App is a Game AND your Game supports Facebook Canvas, you can use the /me/invitable_friends
endpoint in order to render a custom invite dialog, then pass the tokens returned by this API to the standard Requests Dialog.
In other cases, apps are no longer able to retrieve the full list of a user's friends (only those friends who have specifically authorized your app using the user_friends
permission).
For apps wanting allow people to invite friends to use an app, you can still use the Send Dialog on Web or the new Message Dialog on iOS and Android.
fgets would work for you. here is very good documentation on this :-
http://www.cplusplus.com/reference/cstdio/fgets/
If you don't want to use fgets, following method will work for you :-
int readline(FILE *f, char *buffer, size_t len)
{
char c;
int i;
memset(buffer, 0, len);
for (i = 0; i < len; i++)
{
int c = fgetc(f);
if (!feof(f))
{
if (c == '\r')
buffer[i] = 0;
else if (c == '\n')
{
buffer[i] = 0;
return i+1;
}
else
buffer[i] = c;
}
else
{
//fprintf(stderr, "read_line(): recv returned %d\n", c);
return -1;
}
}
return -1;
}
You don't want to take care of normalizing your data in a view - what if the user changes the data that gets submitted? Instead you could take care of it in the model using the before_save
(or the before_validation
) callback. Here's an example of the relevant code for a model like yours:
class Place < ActiveRecord::Base before_save do |place| place.city = place.city.downcase.titleize place.country = place.country.downcase.titleize end end
You can also check out the Ruby on Rails guide for more info.
To answer you question more directly, something like this would work:
<%= f.text_field :city, :value => (f.object.city ? f.object.city.titlecase : '') %>
This just means if f.object.city
exists, display the titlecase
version of it, and if it doesn't display a blank string.
You are having this problem because you are attempting to console log app.address() before the connection has been made. You just have to be sure to console log after the connection is made, i.e. in a callback or after an event signaling that the connection has been made.
Fortunately, the 'listening' event is emitted by the server after the connection is made so just do this:
var express = require('express');
var http = require('http');
var app = express();
var server = http.createServer(app);
app.get('/', function(req, res) {
res.send("Hello World!");
});
server.listen(3000, 'localhost');
server.on('listening', function() {
console.log('Express server started on port %s at %s', server.address().port, server.address().address);
});
This works just fine in nodejs v0.6+ and Express v3.0+.
You can convert BigDecimal
to double
using .doubleValue()
. But believe me, don't use it if you have currency manipulations. It should always be performed on BigDecimal
objects directly. Precision loss in these calculations are big time problems in currency related calculations.
Use
void callClass(Class classObject)
{
//do something with class
}
A Class
is also a Java object, so you can refer to it by using its type.
Read more about it from official documentation.
It lets you define a @Section
of code in your template that you can then include in other files. For example, a sidebar defined in the template, could be referenced in another included view.
//This could be used to render a @Section defined as @Section SideBar { ...
@RenderSection("SideBar", required: false);
Hope this helps.
These are the necersary imports:
import java.io.BufferedReader;
import java.io.FileReader;
import java.io.IOException;
And this is a method that will allow you to read from a File by passing it the filename as a parameter like this: readFile("yourFile.txt");
String readFile(String fileName) throws IOException {
BufferedReader br = new BufferedReader(new FileReader(fileName));
try {
StringBuilder sb = new StringBuilder();
String line = br.readLine();
while (line != null) {
sb.append(line);
sb.append("\n");
line = br.readLine();
}
return sb.toString();
} finally {
br.close();
}
}
None of the examples above create 8-bit (8bpp) bitmap images. Some software, such as image processing, only supports 8bpp. Unfortunately the MS .NET libraries do not have a solution. The PixelFormat.Format8bppIndexed format looks promising but after a lot of attempts I couldn't get it working.
To create a true 8-bit bitmap file you need to create the proper headers. Ultimately I found the Grayscale library solution for creating 8-bit bitmap (BMP) files. The code is very simple:
Image image = Image.FromFile("c:/path/to/image.jpg");
GrayBMP_File.CreateGrayBitmapFile(image, "c:/path/to/8bpp/image.bmp");
The code for this project is far from pretty but it works, with one little simple-to-fix problem. The author hard-coded the image resolution to 10x10. Image processing programs do not like this. The fix is open GrayBMP_File.cs (yeah, funky file naming, I know) and replace lines 50 and 51 with the code below. The example sets the resolution to 200x200 but you should change it to the proper number.
int resX = 200;
int resY = 200;
// horizontal resolution
Copy_to_Index(DIB_header, BitConverter.GetBytes(resX * 100), 24);
// vertical resolution
Copy_to_Index(DIB_header, BitConverter.GetBytes(resY * 100), 28);
Make sure the format of the cell is set to 'general' not 'text' (right click on cell and choose format cell)
Formula should look something like this:
=1+2
Consider this array:
$arr = array("key1" => "value1", "key2" => "value2", "key3" => "value3", "key4" => "value4");
To remove an element using the array key
:
// To unset an element from array using Key:
unset($arr["key2"]);
var_dump($arr);
// output: array(3) { ["key1"]=> string(6) "value1" ["key3"]=> string(6) "value3" ["key4"]=> string(6) "value4" }
To remove element by value
:
// remove an element by value:
$arr = array_diff($arr, ["value1"]);
var_dump($arr);
// output: array(2) { ["key3"]=> string(6) "value3" ["key4"]=> string(6) "value4" }

var_dump($arr);
// array(1) { ["key3"]=> string(6) "value3" }
