You can use ndiff in the difflib module to do this. It has all the information necessary to convert one string into another string.
A simple example:
import difflib
cases=[('afrykanerskojezyczny', 'afrykanerskojezycznym'),
('afrykanerskojezyczni', 'nieafrykanerskojezyczni'),
('afrykanerskojezycznym', 'afrykanerskojezyczny'),
('nieafrykanerskojezyczni', 'afrykanerskojezyczni'),
('nieafrynerskojezyczni', 'afrykanerskojzyczni'),
('abcdefg','xac')]
for a,b in cases:
print('{} => {}'.format(a,b))
for i,s in enumerate(difflib.ndiff(a, b)):
if s[0]==' ': continue
elif s[0]=='-':
print(u'Delete "{}" from position {}'.format(s[-1],i))
elif s[0]=='+':
print(u'Add "{}" to position {}'.format(s[-1],i))
print()
prints:
afrykanerskojezyczny => afrykanerskojezycznym
Add "m" to position 20
afrykanerskojezyczni => nieafrykanerskojezyczni
Add "n" to position 0
Add "i" to position 1
Add "e" to position 2
afrykanerskojezycznym => afrykanerskojezyczny
Delete "m" from position 20
nieafrykanerskojezyczni => afrykanerskojezyczni
Delete "n" from position 0
Delete "i" from position 1
Delete "e" from position 2
nieafrynerskojezyczni => afrykanerskojzyczni
Delete "n" from position 0
Delete "i" from position 1
Delete "e" from position 2
Add "k" to position 7
Add "a" to position 8
Delete "e" from position 16
abcdefg => xac
Add "x" to position 0
Delete "b" from position 2
Delete "d" from position 4
Delete "e" from position 5
Delete "f" from position 6
Delete "g" from position 7
Here's a different example that can't be rewritten without aliases ( can't GROUP BY DISTINCT
).
Imagine a table called purchases
that records purchases made by customers
at stores
, i.e. it's a many to many table and the software needs to know which customers have made purchases at more than one store:
SELECT DISTINCT customer_id, SUM(1)
FROM ( SELECT DISTINCT customer_id, store_id FROM purchases)
GROUP BY customer_id HAVING 1 < SUM(1);
..will break with the error Every derived table must have its own alias
. To fix:
SELECT DISTINCT customer_id, SUM(1)
FROM ( SELECT DISTINCT customer_id, store_id FROM purchases) AS custom
GROUP BY customer_id HAVING 1 < SUM(1);
( Note the AS custom
alias).
I haven't had any problems with the code below. (Relative paths must start with '/' or '\').
private bool IsValidPath(string path, bool allowRelativePaths = false)
{
bool isValid = true;
try
{
string fullPath = Path.GetFullPath(path);
if (allowRelativePaths)
{
isValid = Path.IsPathRooted(path);
}
else
{
string root = Path.GetPathRoot(path);
isValid = string.IsNullOrEmpty(root.Trim(new char[] { '\\', '/' })) == false;
}
}
catch(Exception ex)
{
isValid = false;
}
return isValid;
}
For example these would return false:
IsValidPath("C:/abc*d");
IsValidPath("C:/abc?d");
IsValidPath("C:/abc\"d");
IsValidPath("C:/abc<d");
IsValidPath("C:/abc>d");
IsValidPath("C:/abc|d");
IsValidPath("C:/abc:d");
IsValidPath("");
IsValidPath("./abc");
IsValidPath("./abc", true);
IsValidPath("/abc");
IsValidPath("abc");
IsValidPath("abc", true);
And these would return true:
IsValidPath(@"C:\\abc");
IsValidPath(@"F:\FILES\");
IsValidPath(@"C:\\abc.docx\\defg.docx");
IsValidPath(@"C:/abc/defg");
IsValidPath(@"C:\\\//\/\\/\\\/abc/\/\/\/\///\\\//\defg");
IsValidPath(@"C:/abc/def~`!@#$%^&()_-+={[}];',.g");
IsValidPath(@"C:\\\\\abc////////defg");
IsValidPath(@"/abc", true);
IsValidPath(@"\abc", true);
I was able to use the workspace setting that other people on this page have been asking for.
In Preferences, ?+P, search for python.pythonPath
in the search bar.
You should see something like:
// Path to Python, you can use a custom version of Python by modifying this setting to include the full path.
"python.pythonPath": "python"
Then click on the WORKSPACE SETTINGS tab on the right side of the window. This will make it so the setting is only applicable to the workspace you're in.
Afterwards, click on the pencil icon next to "python.pythonPath". This should copy the setting over the workspace settings.
Change the value to something like:
"python.pythonPath": "${workspaceFolder}/venv"
It is clear that tvi.header
is not a String
. The ==
is an operator that is overloaded by String
class, which means it will be working only if compiler knows that both side of the operator are String
.
Here is how to do it in Unity:
(Modified answer from @markmuetz so be sure to upvote his answer)
int[,] rawNodes = new int[,]
{
{ 0, 0, 0, 0, 0, 0 },
{ 0, 0, 0, 0, 0, 0 },
{ 0, 0, 0, 0, 0, 0 },
{ 0, 0, 0, 0, 0, 0 },
{ 0, 0, 0, 0, 0, 0 }
};
private void Start()
{
int rowLength = rawNodes.GetLength(0);
int colLength = rawNodes.GetLength(1);
string arrayString = "";
for (int i = 0; i < rowLength; i++)
{
for (int j = 0; j < colLength; j++)
{
arrayString += string.Format("{0} ", rawNodes[i, j]);
}
arrayString += System.Environment.NewLine + System.Environment.NewLine;
}
Debug.Log(arrayString);
}
what's the problem with:
field like "*AA*" and field not like "*BB*"
it should be working.
Could you post some example of your data?
function valid(id)
{
var textVal=document.getElementById(id).value;
if (!textVal.match("Tryit")
{
alert("Field says Tryit");
return false;
}
else
{
return true;
}
}
Use this for expressing things
That is not possible with a normal query since the in
clause needs separate values and not a single value containing a comma separated list. One solution would be a dynamic query
declare @myList varchar(100)
set @myList = '(1,2,5,7,10)'
exec('select * from DBTable where id IN ' + @myList)
I think below link might help you -
Here is my attempt:
Function RegParse(ByVal pattern As String, ByVal html As String)
Dim regex As RegExp
Set regex = New RegExp
With regex
.IgnoreCase = True 'ignoring cases while regex engine performs the search.
.pattern = pattern 'declaring regex pattern.
.Global = False 'restricting regex to find only first match.
If .Test(html) Then 'Testing if the pattern matches or not
mStr = .Execute(html)(0) '.Execute(html)(0) will provide the String which matches with Regex
RegParse = .Replace(mStr, "$1") '.Replace function will replace the String with whatever is in the first set of braces - $1.
Else
RegParse = "#N/A"
End If
End With
End Function
One way I've found to do this is to create an img tag and set the src attribute to the file you are looking for. The onload or onerror of the img element will fire based on whether the file exists. You can't load any data using this method, but you can determine if a particular file exists or not.
Years later, but a useful option would be to utilize XPath Axes (https://www.w3schools.com/xml/xpath_axes.asp). More specifically, you are looking to use the descendants axes.
I believe this example would do the trick:
//book[descendant::title[@lang='it']]
This allows you to select all book
elements that contain a child title
element (regardless of how deep it is nested) containing language attribute value equal to 'it'.
I cannot say for sure whether or not this answer is relevant to the year 2009 as I am not 100% certain that the XPath Axes existed at that time. What I can confirm is that they do exist today and I have found them to be extremely useful in XPath navigation and I am sure you will as well.

cmake's ExternalProject_Add
indeed can used, but what I did not like about it - is that it performs something during build, continuous poll, etc... I would prefer to build project during build phase, nothing else. I have tried to override ExternalProject_Add
in several attempts, unfortunately without success.
Then I have tried also to add git submodule, but that drags whole git repository, while in certain cases I need only subset of whole git repository. What I have checked - it's indeed possible to perform sparse git checkout, but that require separate function, which I wrote below.

I have added two function calls below just to illustrate how to use the function.
Someone might not like to checkout master / trunk, as that one might be broken - then it's always possible to specify specific tag.
Checkout will be performed only once, until you clear the cache folder.
<p>Here is a quote from WWF's website:</p>.
In this part <p>
is a tag.
<blockquote cite="www.facebook.com">facebook is the world's largest socialsite..</blockquote>
in this part <blockquote>
is an element.
This is the safest solution:
git stash
Now you can do whatever you want without fear of conflicts.
For instance:
git checkout origin/master
If you want to include the remote changes in the master branch you can do:
git reset --hard origin/master
This will make you branch "master" to point to "origin/master".
Also, you can do this:
FirstClass.this.overridePendingTransition(android.R.anim.slide_in_left, android.R.anim.slide_out_right);
And you don't need to add any animation xml

This is an old question, but here's my two cents. PeterSO's answer is slightly more concise, but slightly less efficient. You already know how big it's going to be so you don't even need to use append:
keys := make([]int, len(mymap))
i := 0
for k := range mymap {
keys[i] = k
i++
}
In most situations it probably won't make much of a difference, but it's not much more work, and in my tests (using a map with 1,000,000 random int64
keys and then generating the array of keys ten times with each method), it was about 20% faster to assign members of the array directly than to use append.
Although setting the capacity eliminates reallocations, append still has to do extra work to check if you've reached capacity on each append.
Here is another solution to the old question. There have been many excellent answers to this question over the years and my attempt borrows heavily from them.
I used Andrey Lebedenko's solution as a starting point because its output was already very close to my requirements.

When I find myself thinking about using Manager
or Helper
in a class name, I consider it a code smell that means I haven't found the right abstraction yet and/or I'm violating the single responsibility principle, so refactoring and putting more effort into design often makes naming much easier.
But even well-designed classes don't (always) name themselves, and your choices partly depend on whether you're creating business model classes or technical infrastructure classes.
Business model classes can be hard, because they're different for every domain. There are some terms I use a lot, like Policy
for strategy classes within a domain (e.g., LateRentalPolicy
), but these usually flow from trying to create a "ubiquitous language" that you can share with business users, designing and naming classes so they model real-world ideas, objects, actions, and events.
Technical infrastructure classes are a bit easier, because they describe domains we know really well. I prefer to incorporate design pattern names into the class names, like InsertUserCommand,
CustomerRepository,
or SapAdapter.
I understand the concern about communicating implementation instead of intent, but design patterns marry these two aspects of class design - at least when you're dealing with infrastructure, where you want the implementation design to be transparent even while you're hiding the details.
chucknorris
starts with c
, and the browser reads it into a hexadecimal value.
Because A, B, C, D, E, and F are characters in hexadecimal.
The browser converts chucknorris
to a hexadecimal value, C00C00000000
.
Then the C00C00000000
hexadecimal value is converted to RGB format (divided by 3):
C00C00000000
?R:C00C, G:0000, B:0000
The browser needs only two digits to indicate the colour:
R:C00C, G:0000, B:0000
?R:C0, G:00, B:00
?C00000
Finally, show bgcolor = C00000
in the web browser.
Here's an example demonstrating it:
<table>
<tr>
<td bgcolor="chucknorris" cellpadding="10" width="150" align="center">chucknorris</td>
<td bgcolor="c00c00000000" cellpadding="10" width="150" align="center">c00c00000000</td>
<td bgcolor="c00000" cellpadding="10" width="150" align="center">c00000</td>
</tr>

diff(1) is not the answer, but comm(1) is.
NAME
comm - compare two sorted files line by line
SYNOPSIS
comm [OPTION]... FILE1 FILE2
...
-1 suppress lines unique to FILE1
-2 suppress lines unique to FILE2
-3 suppress lines that appear in both files
So
comm -2 -3 file1 file2 > file3
The input files must be sorted. If they are not, sort them first. This can be done with a temporary file, or...
comm -2 -3 <(sort file1) <(sort file2) > file3
provided that your shell supports process substitution (bash does).

To avoid that issue, when incrementing time you should convert back to UTC and then add or subtract.
This way you will be able to walk through any periods where hours or minutes happen twice.
If you converted to UTC, add each second, and convert to local time for display. You would go through 11:54:08 p.m. LMT - 11:59:59 p.m. LMT and then 11:54:08 p.m. CST - 11:59:59 p.m. CST.
You can also fix the spaces-in-path problem by specifying the library path in DOS "8.3" format.
To get the 8.3 form, do (at the command line):
DIR /AD /X
recursively through every level of the directories.
I got this error and found that I don't have my SSH port (non standard number) whitelisted in config server firewall.
I found a slight variation on #6 package is out of date from the excellent solution by @Richie Cotton.
Sometimes the package maintainer may show R version gaps that it does not support. In that case, you have at least two options: 1) upgrade your R version to the next one the target package already supports, 2) install the most recent version from the older ones available that would work with your R version.
A concrete example: the latest CRAN version of package rattle
for data mining, 5.3.0, does not support R version 3.4 because it had a big update between package versions 5.2.0 (R >= 2.13.0) and 5.3.0 (R >=3.5).
In a case like this, the alternative to upgrading the R installation is the solution already mentioned. Install the package devtools
if you don't have it (it includes package remotes
) and then install the specific version that will work in your current R. You can look up that information on the CRAN page for the specific package archives.
library("devtools")
install_version("rattle", version = "5.2.0", repos = "http://cran.us.r-project.org")
Since we have a virtual address space of 2^32 and each page size is 2^12, we can store (2^32/2^12) = 2^20 pages. Since each entry into this page table has an address of size 4 bytes, then we have 2^20*4 = 4MB. So the page table takes up 4MB in memory.
This 'hasClass' function works in IE8+, FireFox and Chrome:
hasClass = function(el, cls) {
var regexp = new RegExp('(\\s|^)' + cls + '(\\s|$)'),
target = (typeof el.className === 'undefined') ? window.event.srcElement : el;
return target.className.match(regexp);
}
[Updated Jan'2021] A better way:
hasClass = (el, cls) => {
[...el.classList].includes(cls); //cls without dot
};
simply use delete
, but be aware that you should read fully what the effects are of using this:
delete object.index; //true
object.index; //undefined
but if I was to use like so:
var x = 1; //1
delete x; //false
x; //1
but if you do wish to delete variables in the global namespace, you can use it's global object such as window
, or using this
in the outermost scope i.e
var a = 'b';
delete a; //false
delete window.a; //true
delete this.a; //true
http://perfectionkills.com/understanding-delete/
another fact is that using delete on an array will not remove the index but only set the value to undefined, meaning in certain control structures such as for loops, you will still iterate over that entity, when it comes to array's you should use splice
which is a prototype of the array object.
Example Array:
var myCars=new Array();
myCars[0]="Saab";
myCars[1]="Volvo";
myCars[2]="BMW";
if I was to do:
delete myCars[1];
the resulting array would be:
["Saab", undefined, "BMW"]
but using splice like so:
myCars.splice(1,1);
would result in:
["Saab", "BMW"]
Well, you just fire the desired click event:
$(".first").click(function(){
$(".second").click();
return false;
});
Just a cooler swift syntax for Nate's answer:

let swipe = UISwipeGestureRecognizer(target: self, action: #selector(self.respondToSwipeGesture))
swipe.direction = direction
self.view.addGestureRecognizer(swipe)
})

If you want to go the other way round (associate FILE* with existing file descriptor), use fdopen() :

FILE *fdopen(int fildes, const char *mode);
I don't really understand why you would make this an HTML Helper. I would make it part of the ViewData dictionary in an action method of the controller. Something like this:
ViewData["Age"] = DateTime.Now.Year - birthday.Year;
Given that birthday is passed into an action method and is a DateTime object.
Use with ARCH
flag.
sudo env ARCHFLAGS="-arch x86_64" gem install pg
This resolved the same issue you are having.
In practice, using self-closing tags in HTML should work just like you'd expect. But if you are concerned about writing valid HTML5, you should understand how the use of such tags behaves within the two different two syntax forms you can use. HTML5 defines both an HTML syntax and an XHTML syntax, which are similar but not identical. Which one is used depends on the media type sent by the web server.
More than likely, your pages are being served as text/html
, which follows the more lenient HTML syntax. In these cases, HTML5 allows certain start tags to have an optional / before it's terminating >. In these cases, the / is optional and ignored, so <hr>
and <hr />
are identical. The HTML spec calls these "void elements", and gives a list of valid ones. Strictly speaking, the optional / is only valid within the start tags of these void elements; for example, <br />
and <hr />
are valid HTML5, but <p />
is not.
The HTML5 spec makes a clear distinction between what is correct for HTML authors and for web browser developers, with the second group being required to accept all kinds of invalid "legacy" syntax. In this case, it means that HTML5-compliant browsers will accept illegal self-closed tags, like <p />
, and render them as you probably expect. But for an author, that page would not be valid HTML5. (More importantly, the DOM tree you get from using this kind of illegal syntax can be seriously screwed up; self-closed <span />
tags, for example, tend to mess things up a lot).
(In the unusual case that your server knows how to send XHTML files as an XML MIME type, the page needs to conform to the XHTML DTD and XML syntax. That means self-closing tags are required for those elements defined as such.)
Ok, you must grab the page title before the loop.
$page_title = $wp_query->post->post_title;
Check for the reference: http://codex.wordpress.org/Function_Reference/WP_Query#Properties.
Do a
print_r($wp_query)
before the loop to see all the values of the $wp_query
object.
If you are using Toad for MySQL steps to import a file is as follows:
just delete the file in your ova and it should fix it, thats what i did, no need to run program under admin or anything. didnt delete my deployed files either. (I was trying to create new virtual machines not open them)
The other answers are probably sufficient in most cases but I thought I'd add my two cents as I ran into a problem on a BusyBox system.
The system in question did not support the %N
format option and doesn't have no Python or Perl interpreter.
After much head scratching, we (thanks Dave!) came up with this:
adjtimex | awk '/(time.tv_sec|time.tv_usec):/ { printf("%06d", $2) }'
It extracts the seconds and microseconds from the output of adjtimex
(normally used to set options for the system clock) and prints them without new lines (so they get glued together). Note that the microseconds field has to be pre-padded with zeros, but this doesn't affect the seconds field which is longer than six digits anyway. From this it should be trivial to convert microseconds to milliseconds.
If you need a trailing new line (maybe because it looks better) then try
adjtimex | awk '/(time.tv_sec|time.tv_usec):/ { printf("%06d", $2) }' && printf "\n"
Also note that this requires adjtimex
and awk
to be available. If not then with BusyBox you can point to them locally with:
ln -s /bin/busybox ./adjtimex
ln -s /bin/busybox ./awk
And then call the above as
./adjtimex | ./awk '/(time.tv_sec|time.tv_usec):/ { printf("%06d", $2) }'
Or of course you could put them in your PATH
EDIT:
The above worked on my BusyBox device. On Ubuntu I tried the same thing and realised that adjtimex
has different versions. On Ubuntu this worked to output the time in seconds with decimal places to microseconds (including a trailing new line)
sudo apt-get install adjtimex
adjtimex -p | awk '/raw time:/ { print $6 }'
I wouldn't do this on Ubuntu though. I would use date +%s%N
You can try the regex here to filter out the columns starting with "foo"
df.filter(regex='^foo*')
If you need to have the string foo in your column then
df.filter(regex='foo*')
would be appropriate.
For the next step, you can use
df[df.filter(regex='^foo*').values==1]
to filter out the rows where one of the values of 'foo*' column is 1.
There is a new function in SQL called string_split
if you are using list of string.
Ref Link STRING_SPLIT (Transact-SQL)
DECLARE @tags NVARCHAR(400) = 'clothing,road,,touring,bike'
SELECT value
FROM STRING_SPLIT(@tags, ',')
WHERE RTRIM(value) <> '';
you can pass this query with in
as follows:
SELECT *
FROM [dbo].[yourTable]
WHERE (strval IN (SELECT value FROM STRING_SPLIT(@tags, ',') WHERE RTRIM(value) <> ''))
use this syntax: alter table table_name modify column col_name varchar (10000);
If I had to guess, I'd say you installed the PPA 7.1.8 as CLI only (php7-cli). You're getting your version info from that, but your libapache2-mod-php package is still 14.04 main which is 5.6. Check your phpinfo in your browser to confirm the version. You might also consider migrating to Ubuntu 16.04 to get PHP 7.0 in main.
In iOS 6 you can easily use:
NSUUID *UUID = [NSUUID UUID];
NSString* stringUUID = [UUID UUIDString];

This is a matplotlib question, and you can get around this by using a backend that doesn't display to the user, e.g. 'Agg':
import matplotlib
matplotlib.use('Agg')
import matplotlib.pyplot as plt
plt.plot([1,2,3])
plt.savefig('/tmp/test.png')
EDIT: If you don't want to lose the ability to display plots, turn off Interactive Mode, and only call plt.show()
when you are ready to display the plots:
import matplotlib.pyplot as plt
# Turn interactive plotting off
plt.ioff()
# Create a new figure, plot into it, then close it so it never gets displayed
fig = plt.figure()
plt.plot([1,2,3])
plt.savefig('/tmp/test0.png')
plt.close(fig)
# Create a new figure, plot into it, then don't close it so it does get displayed
plt.figure()
plt.plot([1,3,2])
plt.savefig('/tmp/test1.png')
# Display all "open" (non-closed) figures
plt.show()
I don't know TeamCity so I hope this can work for you.
The best way I've found to do this is with MSDeploy.exe. This is part of the WebDeploy project run by Microsoft. You can download the bits here.
With WebDeploy, you run the command line
msdeploy.exe -verb:sync -source:contentPath=c:\webApp -dest:contentPath=c:\DeployedWebApp
This does the same thing as the VS Publish command, copying only the necessary bits to the deployment folder.
You can't define static methods in an interface because static methods belongs to a class not to an instance of class, and interfaces are not Classes. Read more here.
However, If you want you can do this:
public class A {
public static void methodX() {
}
}
public class B extends A {
public static void methodX() {
}
}
In this case what you have is two classes with 2 distinct static methods called methodX().
I have created a custom model binder which converts any comma separated values (only primitive, decimal, float, string) to their corresponding arrays.
public class CommaSeparatedToArrayBinder<T> : IModelBinder
{
public bool BindModel(HttpActionContext actionContext, ModelBindingContext bindingContext)
{
Type type = typeof(T);
if (type.IsPrimitive || type == typeof(Decimal) || type == typeof(String) || type == typeof(float))
{
ValueProviderResult val = bindingContext.ValueProvider.GetValue(bindingContext.ModelName);
if (val == null) return false;
string key = val.RawValue as string;
if (key == null) { bindingContext.ModelState.AddModelError(bindingContext.ModelName, "Wrong value type"); return false; }
string[] values = key.Split(',');
IEnumerable<T> result = this.ConvertToDesiredList(values).ToArray();
bindingContext.Model = result;
return true;
}
bindingContext.ModelState.AddModelError(bindingContext.ModelName, "Only primitive, decimal, string and float data types are allowed...");
return false;
}
private IEnumerable<T> ConvertToDesiredArray(string[] values)
{
foreach (string value in values)
{
var val = (T)Convert.ChangeType(value, typeof(T));
yield return val;
}
}
}
And how to use in Controller:
public IHttpActionResult Get([ModelBinder(BinderType = typeof(CommaSeparatedToArrayBinder<int>))] int[] ids)
{
return Ok(ids);
}
Works in Net Core 2.1
var file = Path.Combine(Directory.GetCurrentDirectory(), "wwwroot", "email", "EmailRegister.htm");
string SendData = System.IO.File.ReadAllText(file);
Inserting date in sql
insert
into tablename (timestamp_value)
values ('dd-mm-yyyy hh-mm-ss AM');
If suppose we wanted to insert system date
insert
into tablename (timestamp_value)
values (sysdate);
That true,Mustafa....its working..its point to two layout
You should take Button both activity layout...
solve this problem successfully
Maybe I'm not understanding the question but here is my simple solution that works -
# I want to Display total heads bent this machine so I define a label -
TotalHeadsLabel3 = Label(leftFrame)
TotalHeadsLabel3.config(font=Helv12,fg='blue',text="Total heads " + str(TotalHeads))
TotalHeadsLabel3.pack(side=TOP)
# I update the int variable adding the quantity bent -
TotalHeads = TotalHeads + headQtyBent # update ready to write to file & display
TotalHeadsLabel3.config(text="Total Heads "+str(TotalHeads)) # update label with new qty
I agree that labels are not automatically updated but can easily be updated with the
<label name>.config(text="<new text>" + str(<variable name>))
That just needs to be included in your code after the variable is updated.
And using ports:
port install gradle
Ports , tested on El Capitan
Had the same problem, but solved it in a different way. It might not be the best solution, but its a solution.
in app.config:
<add key="errorMailFirst" value="[email protected]"/>
<add key="errorMailSeond" value="[email protected]"/>
Then in my configuration wrapper class, I add a method to search keys.
public List<string> SearchKeys(string searchTerm)
{
var keys = ConfigurationManager.AppSettings.Keys;
return keys.Cast<object>()
.Where(key => key.ToString().ToLower()
.Contains(searchTerm.ToLower()))
.Select(key => ConfigurationManager.AppSettings.Get(key.ToString())).ToList();
}
For anyone reading this, i agree that creating your own custom configuration section is cleaner, and more secure, but for small projects, where you need something quick, this might solve it.
For Converting a List into Pandas Core Data Frame, we need to use DataFrame Method from pandas Package.
There are Different Ways to Perform the Above Operation.
import pandas as pd
Data = pd.DataFrame(Column_Data)
Data.columns = ['Column_Name']
So, for the above mentioned issue, the code snippet is
import pandas as pd
Content = ['Thanks You',
'Its fine no problem',
'Are you sure']
Data = pd.DataFrame({'Text': Content})
In oracle db there is a trick for casting int to float (I suppose, it should also work in mysql):
select myintfield + 0.0 as myfloatfield from mytable
While @Heximal's answer works, I don't personally recommend it.
This is because it uses implicit casting. Although you didn't type CAST
, either the SUM()
or the 0.0
need to be cast to be the same data-types, before the +
can happen. In this case the order of precedence is in your favour, and you get a float on both sides, and a float as a result of the +
. But SUM(aFloatField) + 0
does not yield an INT, because the 0
is being implicitly cast to a FLOAT.
I find that in most programming cases, it is much preferable to be explicit. Don't leave things to chance, confusion, or interpretation.
If you want to be explicit, I would use the following.
CAST(SUM(sl.parts) AS FLOAT) * cp.price
-- using MySQL CAST FLOAT requires 8.0
You can try the following to see what happens...
CAST(SUM(sl.parts) AS NUMERIC(10,4)) * CAST(cp.price AS NUMERIC(10,4))
If You want make json object from yor model do like this :
foreach (var item in Persons)
{
var jsonObj=["FirstName":"@item.FirstName"]
}
Or Use Json.Net to make json from your model :
string json = JsonConvert.SerializeObject(person);
Unit Test - testing an individual unit, such as a method (function) in a class, with all dependencies mocked up.
Functional Test - AKA Integration Test, testing a slice of functionality in a system. This will test many methods and may interact with dependencies like Databases or Web Services.
You should be able to find your command with a ps
variant like:
ps -ef
ps -fubob # if your job's user ID is bob.
Then, once located, it should be a simple matter to use kill
to kill the process (permissions permitting).
If you're talking about getting rid of jobs in the at
queue (that aren't running yet), you can use atq
to list them and atrm
to get rid of them.
You can emulate goto's functionality with exceptions:
try:
# blah, blah ...
# raise MyFunkyException as soon as you want out
except MyFunkyException:
pass
Disclaimer: I only mean to bring to your attention the possibility of doing things this way, while in no way do I endorse it as reasonable under normal circumstances. As I mentioned in a comment on the question, structuring code so as to avoid Byzantine conditionals in the first place is preferable by far. :-)
For me this was thrown when running unit tests under MSTest
(VS2015). Had to add
<startup useLegacyV2RuntimeActivationPolicy="true">
</startup>
in
C:\Program Files (x86)\Microsoft Visual Studio 14.0\Common7\IDE\CommonExtensions\Microsoft\TestWindow\TE.ProcessHost.Managed.exe.config
This helped for me:
$("#input").keyup(function(event) {
//use keyup instead keypress because:
//- keypress will not work on backspace and delete
//- keypress is called before the character is added to the textfield (at least in google chrome)
var searchText = $.trim($("#input").val());
var c= String.fromCharCode(event.keyCode);
var isWordCharacter = c.match(/\w/);
var isBackspaceOrDelete = (event.keyCode == 8 || event.keyCode == 46);
// trigger only on word characters, backspace or delete and an entry size of at least 3 characters
if((isWordCharacter || isBackspaceOrDelete) && searchText.length > 2)
{ ...
This is what worked for me: Using Gradle 4.8.1
buildscript {
ext.kotlin_version = '1.1.1'
repositories {
jcenter()
google()
}
dependencies {
classpath 'com.android.tools.build:gradle:3.1.0'}
}
allprojects {
repositories {
mavenLocal()
jcenter()

maven {
url "$rootDir/../node_modules/react-native/android"
}
maven {

}
}
}
Using jQuery, we can use the following code:
Select by input name:
$('input[name="textboxname"]').val('some value')
Select by input class:
$('input[type=text].textboxclass').val('some value')
Select by input id:
$('#textboxid').val('some value')
Using exit
directly may be tricky as the script may be sourced from other places (e.g. from terminal). I prefer instead using subshell with set -e
(plus errors should go into cerr, not cout) :
set -e
ERRCODE=0
my_command || ERRCODE=$?
test $ERRCODE == 0 ||
(>&2 echo "My command failed ($ERRCODE)"; exit $ERRCODE)
I found this as an easiest way to add row . The awesome thing about this is that it doesn't change the already present table contents even if it contains input elements .
row = `<tr><td><input type="text"></td></tr>`
$("#table_body tr:last").after(row) ;
Here #table_body
is the id of the table body tag .
There are two types of LinearSegmentedColormaps. In some, the _segmentdata is given explicitly, e.g., for jet:
>>> cm.jet._segmentdata
{'blue': ((0.0, 0.5, 0.5), (0.11, 1, 1), (0.34, 1, 1), (0.65, 0, 0), (1, 0, 0)), 'red': ((0.0, 0, 0), (0.35, 0, 0), (0.66, 1, 1), (0.89, 1, 1), (1, 0.5, 0.5)), 'green': ((0.0, 0, 0), (0.125, 0, 0), (0.375, 1, 1), (0.64, 1, 1), (0.91, 0, 0), (1, 0, 0))}
For rainbow, _segmentdata is given as follows:
>>> cm.rainbow._segmentdata
{'blue': <function <lambda> at 0x7fac32ac2b70>, 'red': <function <lambda> at 0x7fac32ac7840>, 'green': <function <lambda> at 0x7fac32ac2d08>}
We can find the functions in the source of matplotlib, where they are given as
_rainbow_data = {
'red': gfunc[33], # 33: lambda x: np.abs(2 * x - 0.5),
'green': gfunc[13], # 13: lambda x: np.sin(x * np.pi),
'blue': gfunc[10], # 10: lambda x: np.cos(x * np.pi / 2)
}
Everything you want is already done in matplotlib, just call cm.revcmap, which reverses both types of segmentdata, so
cm.revcmap(cm.rainbow._segmentdata)
should do the job - you can simply create a new LinearSegmentData from that. In revcmap, the reversal of function based SegmentData is done with
def _reverser(f):
def freversed(x):
return f(1 - x)
return freversed
while the other lists are reversed as usual
valnew = [(1.0 - x, y1, y0) for x, y0, y1 in reversed(val)]
So actually the whole thing you want, is
def reverse_colourmap(cmap, name = 'my_cmap_r'):
return mpl.colors.LinearSegmentedColormap(name, cm.revcmap(cmap._segmentdata))
Here's how to do Richard Christensen's answer as a one-liner, no file editing required (replace capitalized with your own settings, PROXYPORT is frequently 80):
ssh USER@FINAL_DEST -o "ProxyCommand=nc -X connect -x PROXYHOST:PROXYPORT %h %p"
You can use the same -o ...
option for scp as well, see https://superuser.com/a/752621/39364
If you get this in OS X:
nc: invalid option -- X
Try `nc --help' for more information.
it may be that you're accidentally using the homebrew version of netcat (you can see by doing a which -a nc
command--/usr/bin/nc
should be listed first). If there are two then one workaround is to specify the full path to the nc you want, like ProxyCommand=/usr/bin/nc
...
For CentOS nc
has the same problem of invalid option --X
. connect-proxy
is an alternative, easy to install using yum
and works --
ssh -o ProxyCommand="connect-proxy -S PROXYHOST:PROXYPORT %h %p" USER@FINAL_DEST
This code worked well with new version (v0.8.12) (2019-05-21)

});
};
PHP Code (upload.php)
if ($_FILES['file']['name']) {
if (!$_FILES['file']['error']) {
$name = md5(rand(100, 200));
$ext = explode('.', $_FILES['file']['name']);
$filename = $name . '.' . $ext[1];
$destination = 'images/' . $filename; //change this directory
$location = $_FILES["file"]["tmp_name"];
move_uploaded_file($location, $destination);
echo 'images/' . $filename;//change this URL
}
else
{
echo $message = 'Ooops! Your upload triggered the following error: '.$_FILES['file']['error'];
}
}
you can try this and don't need JQuery: timeSolver.js
For example, add 5 day on today:
var newDay = timeSolver.add(new Date(),5,"day");
You also can add by hour, month...etc. please see for more infomation.
Another alternate approach to Diego's is to use a library:
https://github.com/airbnb/DeepLinkDispatch
You can easily declare the URIs you'd like to handle and the parameters you'd like to extract through annotations on the Activity, like:
@DeepLink("path/to/what/i/want")
public class SomeActivity extends Activity {
...
}
As a plus, the query parameters will also be passed along to the Activity as well.
Here's another way I implemented (didn't test it with an unwind segue but it probably wouldn't differentiate, as others have stated in regards to other solutions on this page) to have the parent view controller perform actions before the child VC it pushed gets popped off the view stack (I used this a couple levels down from the original UINavigationController). This could also be used to perform actions before the childVC gets pushed, too. This has the added advantage of working with the iOS system back button, instead of having to create a custom UIBarButtonItem or UIButton.
Have your parent VC adopt the UINavigationControllerDelegate
protocol and register for delegate messages:
MyParentViewController : UIViewController <UINavigationControllerDelegate>
-(void)viewDidLoad {
self.navigationcontroller.delegate = self;
}
Implement this UINavigationControllerDelegate
instance method in MyParentViewController
:
- (id<UIViewControllerAnimatedTransitioning>)navigationController:(UINavigationController *)navigationController animationControllerForOperation:(UINavigationControllerOperation)operation fromViewController:(UIViewController *)fromVC toViewController:(UIViewController *)toVC {
// Test if operation is a pop; can also test for a push (i.e., do something before the ChildVC is pushed
if (operation == UINavigationControllerOperationPop) {
// Make sure it's the child class you're looking for
if ([fromVC isKindOfClass:[ChildViewController class]]) {
// Can handle logic here or send to another method; can also access all properties of child VC at this time
return [self didPressBackButtonOnChildViewControllerVC:fromVC];
}
}
// If you don't want to specify a nav controller transition
return nil;
}
If you specify a specific callback function in the above UINavigationControllerDelegate
instance method
-(id <UIViewControllerAnimatedTransitioning>)didPressBackButtonOnAddSearchRegionsVC:(UIViewController *)fromVC {
ChildViewController *childVC = ChildViewController.new;
childVC = (ChildViewController *)fromVC;
// childVC.propertiesIWantToAccess go here
// If you don't want to specify a nav controller transition
return nil;
}
Given the interface:
public interface IAnything {
int i;
void m1();
void m2();
void m3();
}
This is how Java actually sees it:
public interface IAnything {
public static final int i;
public abstract void m1();
public abstract void m2();
public abstract void m3();
}
So you can leave some (or all) of these abstract
methods unimplemented, just as you would do in the case of abstract
classes extending another abstract
class.
When you implement
an interface
, the rule that all interface
methods must be implemented in the derived class
, applies only to concrete class
implementation (i.e., which isn't abstract
itself).
If you indeed plan on creating an abstract class
out of it, then there is no rule that says you've to implement
all the interface
methods (note that in such a case it is mandatory to declare the derived class
as abstract
)

>>> import json
Then with python2 :
>>> print json.dumps(mydict, indent=4, sort_keys=True) # python 2
{
"a": 1,
"b": 2,
"c": 3
}
or with python 3 :
>>> print(json.dumps(mydict, indent=4, sort_keys=True)) # python 3
{
"a": 1,
"b": 2,
"c": 3
}
I've added jsperf test to see the speed difference for different approaches to get the first child (total 1000+ children)
given, notif = $('#foo')
jQuery ways:
$(":first-child", notif)
- 4,304 ops/sec - fastestnotif.children(":first")
- 653 ops/sec - 85% slowernotif.children()[0]
- 1,416 ops/sec - 67% slowerNative ways:
ele.firstChild
- 4,934,323 ops/sec (all the above approaches are 100% slower compared to firstChild
)notif[0].firstChild
- 4,913,658 ops/secSo, first 3 jQuery approaches are not recommended, at least for first-child (I doubt that would be the case with many other too). If you have a jQuery object and need to get the first-child, then get the native DOM element from the jQuery object, using array reference [0]
(recommended) or .get(0)
and use the ele.firstChild
. This gives the same identical results as regular JavaScript usage.
all tests are done in Chrome Canary build v15.0.854.0
Basically, ajax request as well as synchronous request sends your document cookies automatically. So, you need to set your cookie to document, not to request. However, your request is cross-domain, and things became more complicated. Basing on this answer, additionally to set document cookie, you should allow its sending to cross-domain environment:
type: "GET",
url: "http://example.com",
cache: false,
// NO setCookies option available, set cookie to document
//setCookies: "lkfh89asdhjahska7al446dfg5kgfbfgdhfdbfgcvbcbc dfskljvdfhpl",
crossDomain: true,
dataType: 'json',
xhrFields: {
withCredentials: true
},
success: function (data) {
alert(data);
});
When they say "The bottom of the page" they don't literally mean the bottom: they mean just before the closing </body>
tag. Place your scripts there and they will be loaded before the DOMReady event; place them afterwards and the DOM will be ready before they are loaded (because it's complete when the closing </html>
tag is parsed), which as you have found will not work.
If you're wondering how I know that this is what they mean: I have worked at Yahoo! and we put our scripts just before the </body>
tag :-)
EDIT: also, see T.J. Crowder's reply and make sure you have things in the correct order.
In Python 2:
>>> "7061756c".decode("hex")
'paul'
In Python 3:
>>> bytes.fromhex('7061756c').decode('utf-8')

A char
variable is actually an 8-bit integral value. It will have values from 0
to 255
. These are ASCII codes. 0
stands for the C-null character, and 255
stands for an empty symbol.
So, when you write the following assignment:
char a = 'a';
It is the same thing as:
char a = 97;
So, you can compare two char
variables using the >
, <
, ==
, <=
, >=
operators:
char a = 'a';
char b = 'b';
if( a < b ) printf("%c is smaller than %c", a, b);
if( a > b ) printf("%c is smaller than %c", a, b);
if( a == b ) printf("%c is equal to %c", a, b);

This query (which is similar to what bayuah posted) shows a nice summary of all tables count inside a database: (simplified version of stored procedure by Ivan Cachicatari which I highly recommend).

hbn's answer won't work out of the box if the file to load is in a subdirectory or is named with dashes.
In such a case you may consider this alternative :
exec open(myconfig.py).read()
Or the simpler but deprecated in python3 :
execfile(myconfig.py)
I guess Stephan202's warning applies to both options, though, and maybe the loop on lines is safer.
curl -s -v -o/dev/null -H "Testheader: test" http://www.example.com
You could also use -I
option if you want to send a HEAD request and not a GET request.
Complementing Marco Bonelli's answer: the best current way of interacting between frames/iframes is using window.postMessage

Code Snippet:

just to be pythonic :-)
>>> x = ['a1sd','23df','aaa','ccc','rrrr', 'ssss', 'e', '']
>>> [x[i] + x[i+1] for i in range(0,len(x),2)]
['a1sd23df', 'aaaccc', 'rrrrssss', 'e']
in case the you want to be alarmed if the list length is odd you can try:
[x[i] + x[i+1] if not len(x) %2 else 'odd index' for i in range(0,len(x),2)]
Best of Luck
Here's yet another, slightly different answer with a few enhancements.
This code takes the .jar right out of the .aar. Personally, that gives me a bit more confidence that the bits being shipped via .jar are the same as the ones shipped via .aar. This also means that if you're using ProGuard, the output jar will be obfuscated as desired.
I also added a super "makeJar" task, that makes jars for all build variants.
task(makeJar) << {
// Empty. We'll add dependencies for this task below
}
// Generate jar creation tasks for all build variants
android.libraryVariants.all { variant ->
String taskName = "makeJar${variant.name.capitalize()}"
// Create a jar by extracting it from the assembled .aar
// This ensures that products distributed via .aar and .jar exactly the same bits
task (taskName, type: Copy) {
String archiveName = "${project.name}-${variant.name}"
String outputDir = "${buildDir.getPath()}/outputs"
dependsOn "assemble${variant.name.capitalize()}"
from(zipTree("${outputDir}/aar/${archiveName}.aar"))
into("${outputDir}/jar/")
include('classes.jar')
rename ('classes.jar', "${archiveName}-${variant.mergedFlavor.versionName}.jar")
}
makeJar.dependsOn tasks[taskName]
}
For the curious reader, I struggled to determine the correct variables and parameters that the com.android.library plugin uses to name .aar files. I finally found them in the Android Open Source Project here.
getTitle
is a function, so you need to put ()
after it.
string t = obj.getTitle();
ALTER TABLE [table_name] ALTER COLUMN [column_name] varchar(150)
Since you declare sample
inside the anonymous function you pass to ready
, it is scoped to that function.
You then pass a string to setTimeout
which is eval
ed after 2 seconds. This takes place outside the current scope, so it can't find the function.
Only pass functions to setTimeout
, using eval is inefficient and hard to debug.

In the newer version of mongodb v2.6.4 try:
grep dbpath /etc/mongod.conf
It will give you something like this:
dbpath=/var/lib/mongodb
And that is where it stores the data.
In my case, I needed to check for the existence of a method with a specific name, so I used an interface for that
var plugin = this.pluginFinder.GetPluginIfInstalled<IPlugin>(pluginName) as dynamic;
if (plugin != null && plugin is ICustomPluginAction)
{
plugin.CustomPluginAction(action);
}
Also, interfaces can contain more than just methods:
Interfaces can contain methods, properties, events, indexers, or any combination of those four member types.

This is backwards from what Bootstrap is designed for, but you can do this:
<div class="row">
<div class="col-xs-4 col-md-12">.col-xs-4 .col-md-12</div>
<div class="col-xs-4 col-md-12">.col-xs-4 .col-md-12</div>

This will make each element 33.3% wide on small and extra small devices but 100% wide on medium and larger devices.
JSFiddle: http://jsfiddle.net/jdwire/sggt8/embedded/result/
I think you're looking for the visible-xs
and/or visible-sm
classes. These will let you make certain elements only visible to small screen devices.
For example, if you want a element to only be visible to small and extra-small devices, do this:
<div class="visible-xs visible-sm">You're using a fairly small device.</div>
To show it only for larger screens, use this:
<div class="hidden-xs hidden-sm">You're probably not using a phone.</div>

In this tutorial is explained how to consume a web api with C#, in this example a console application is used, but you can also use another web api to consume of course.
http://www.asp.net/web-api/overview/web-api-clients/calling-a-web-api-from-a-net-client
You should have a look at the HttpClient
HttpClient client = new HttpClient();
client.BaseAddress = new Uri("http://localhost/yourwebapi");
Make sure your requests ask for the response in JSON using the Accept header like this:
client.DefaultRequestHeaders.Accept.Add(
new MediaTypeWithQualityHeaderValue("application/json"));
Now comes the part that differs from the tutorial, make sure you have the same objects as the other WEB API
, if not, then you have to map the objects to your own objects. ASP.NET
will convert the JSON
you receive to the object you want it to be.
HttpResponseMessage response = client.GetAsync("api/yourcustomobjects").Result;
if (response.IsSuccessStatusCode)
{
var yourcustomobjects = response.Content.ReadAsAsync<IEnumerable<YourCustomObject>>().Result;
foreach (var x in yourcustomobjects)
{
//Call your store method and pass in your own object
SaveCustomObjectToDB(x);
}
}
else
{
//Something has gone wrong, handle it here
}
please note that I use .Result
for the case of the example. You should consider using the async
await
pattern here.
Had the same problem recently on IE11 with Windows 7. Applets worked fine before but they stop working from one day to another. I solved it adding the applet sites to trusted sites and config this with low security level.
I don't try to answer all of my questions, as I believe it is too broad. Just a couple of notes:
there are cases when object construction is a task complex enough to justify its extraction to another class.
That class is in fact a Builder, rather than a Factory.
In the general case, I don't want to force the users of the factory to be restrained to dynamic allocation.
Then you could have your factory encapsulate it in a smart pointer. I believe this way you can have your cake and eat it too.
This also eliminates the issues related to return-by-value.
Conclusion: Making a factory by returning an object is indeed a solution for some cases (such as the 2-D vector previously mentioned), but still not a general replacement for constructors.
Indeed. All design patterns have their (language specific) constraints and drawbacks. It is recommended to use them only when they help you solve your problem, not for their own sake.
If you are after the "perfect" factory implementation, well, good luck.

I had the same problem, so I dug through the poi-3.17.jar file and there was no xssf package inside.
I then went through the other files and found xssf int the poi-ooxml-3.17.jar

poi-ooxml-3.17.jar
to your project, as that seems to make it work (for me at least)
Unfortunately SQL Server interprets the quoted comma as a delimiter. This applies to both BCP and bulk insert .
From http://msdn.microsoft.com/en-us/library/ms191485%28v=sql.100%29.aspx
If a terminator character occurs within the data, it is interpreted as a terminator, not as data, and the data after that character is interpreted as belonging to the next field or record. Therefore, choose your terminators carefully to make sure that they never appear in your data.
You have to give the values between 0 and 1.0. So divide the RGB values by 255.
myLabel.textColor= [UIColor colorWithRed:(160/255.0) green:(97/255.0) blue:(5/255.0) alpha:1] ;
Update:
You can also use this macro
#define Rgb2UIColor(r, g, b) [UIColor colorWithRed:((r) / 255.0) green:((g) / 255.0) blue:((b) / 255.0) alpha:1.0]
and you can call in any of your class like this
myLabel.textColor = Rgb2UIColor(160, 97, 5);
This is the normal color synax
myLabel.textColor = UIColor(red: (160/255.0), green: (97/255.0), blue: (5/255.0), alpha: 1.0)
//The values should be between 0 to 1
Swift is not much friendly with macros
Complex macros are used in C and Objective-C but have no counterpart in Swift. Complex macros are macros that do not define constants, including parenthesized, function-like macros. You use complex macros in C and Objective-C to avoid type-checking constraints or to avoid retyping large amounts of boilerplate code. However, macros can make debugging and refactoring difficult. In Swift, you can use functions and generics to achieve the same results without any compromises. Therefore, the complex macros that are in C and Objective-C source files are not made available to your Swift code.
So we use extension for this
extension UIColor {
convenience init(_ r: Double,_ g: Double,_ b: Double,_ a: Double) {
self.init(red: r/255, green: g/255, blue: b/255, alpha: a)
}
}
You can use it like
myLabel.textColor = UIColor(160.0, 97.0, 5.0, 1.0)
setTimeout(function () { location.reload(1); }, 5000);
But as development tools go, you are probably better off with https://addons.mozilla.org/en-US/firefox/addon/115
Pure4J supports what you are after, in two ways.
First, it provides an @ImmutableValue
annotation, so that you can annotate a class to say that it is immutable. There is a maven plugin to allow you to check that your code actually is immutable (use of final
etc.).
Second, it provides the persistent collections from Clojure, (with added generics) and ensures that elements added to the collections are immutable. Performance of these is apparently pretty good. Collections are all immutable, but implement java collections interfaces (and generics) for inspection. Mutation returns new collections.
Disclaimer: I'm the developer of this
Setting the Color property alone will guarantee an exact match. Excel 2003 can only handle 56 colors at once. The good news is that you can assign any rgb value at all to those 56 slots (which are called ColorIndexs). When you set a cell's color using the Color property this causes Excel to use the nearest "ColorIndex". Example: Setting a cell to RGB 10,20,50 (or 3281930) will actually cause it to be set to color index 56 which is 51,51,51 (or 3355443).
If you want to be assured you got an exact match, you need to change a ColorIndex to the RGB value you want and then change the Cell's ColorIndex to said value. However you should be aware that by changing the value of a color index you change the color of all cells already using that color within the workbook. To give an example, Red is ColorIndex 3. So any cell you made Red you actually made ColorIndex 3. And if you redefine ColorIndex 3 to be say, purple, then your cell will indeed be made purple, but all other red cells in the workbook will also be changed to purple.
There are several strategies to deal with this. One way is to choose an index not yet in use, or just one that you think will not be likely to be used. Another way is to change the RGB value of the nearest ColorIndex so your change will be subtle. The code I have posted below takes this approach. Taking advantage of the knowledge that the nearest ColorIndex is assigned, it assigns the RGB value directly to the cell (thereby yielding the nearest color) and then assigns the RGB value to that index.
Sub Example()
Dim lngColor As Long
lngColor = RGB(10, 20, 50)
With Range("A1").Interior
.Color = lngColor
ActiveWorkbook.Colors(.ColorIndex) = lngColor
End With
End Sub
Try this sample. It works for me.
public static void main(String[] args) {
Logger logger = Logger.getLogger("MyLog");
FileHandler fh;
try {
// This block configure the logger with handler and formatter
fh = new FileHandler("C:/temp/test/MyLogFile.log");
logger.addHandler(fh);
SimpleFormatter formatter = new SimpleFormatter();
fh.setFormatter(formatter);
// the following statement is used to log any messages
logger.info("My first log");
} catch (SecurityException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
logger.info("Hi How r u?");
}

INFO: My first log
Apr 2, 2013 9:57:08 AM testing.MyLogger main
INFO: Hi How r u?
Edit:
To remove the console handler, use
logger.setUseParentHandlers(false);
since the ConsoleHandler is registered with the parent logger from which all the loggers derive.
value_counts omits NaN by default so you're most likely dealing with "".
So you can just filter them out like
filter = df["Tenant"] != ""
dfNew = df[filter]
From docs TWIG docs:
Unlike in PHP, it's not possible to break or continue in a loop.
But still:
You can however filter the sequence during iteration which allows you to skip items.
Example 1 (for huge lists you can filter posts using slice, slice(start, length)
):
{% for post in posts|slice(0,10) %}
<h2>{{ post.heading }}</h2>
{% endfor %}
Example 2:
{% for post in posts if post.id < 10 %}
<h2>{{ post.heading }}</h2>
{% endfor %}
You can even use own TWIG filters for more complexed conditions, like:
{% for post in posts|onlySuperPosts %}
<h2>{{ post.heading }}</h2>
{% endfor %}
Apparently YouTube constantly polls for Google Cast scripts even if the extension isn't installed.
From one commenter:
... it appears that Chrome attempts to get cast_sender.js on pages that have YouTube content. I'm guessing when Chrome sees media that it can stream it attempts to access the Chromecast extension. When the extension isn't present, the error is thrown.
The only solution I've come across is to install the Google Cast extension, whether you need it or not. You may then hide the toolbar button.
For more information and updates, see this SO question. Here's the official issue.
I do it this way:
SELECT a.* FROM articles AS a
LEFT JOIN articles AS a2
ON a.section = a2.section AND a.article_date <= a2.article_date
GROUP BY a.article_id
HAVING COUNT(*) <= 10;
update: This example of GROUP BY works in MySQL and SQLite only, because those databases are more permissive than standard SQL regarding GROUP BY. Most SQL implementations require that all columns in the select-list that aren't part of an aggregate expression are also in the GROUP BY.
$('#form').append('<input type="text" value="'+yourValue+'" />');
How about this?
SELECT Value, ReadTime, ReadDate
FROM YOURTABLE
WHERE CAST(ReadDate AS DATETIME) + ReadTime BETWEEN '2010-09-16 17:00:00' AND '2010-09-21 09:00:00'
EDIT: output according to OP's wishes ;-)
The third parameter of String.prototype.replace()
function was never defined as a standard, so most browsers simply do not implement it.
g
(global) flag.var myStr = 'this,is,a,test';_x000D_
var newStr = myStr.replace(/,/g, '-');_x000D_
_x000D_
console.log( newStr ); // "this-is-a-test"
_x000D_
It is important to note, that regular expressions use special characters that need to be escaped. As an example, if you need to escape a dot (.
) character, you should use /\./
literal, as in the regex syntax a dot matches any single character (except line terminators).
var myStr = 'this.is.a.test';_x000D_
var newStr = myStr.replace(/\./g, '-');_x000D_
_x000D_
console.log( newStr ); // "this-is-a-test"
_x000D_
If you need to pass a variable as a replacement string, instead of using regex literal you may create RegExp
object and pass a string as the first argument of the constructor. The normal string escape rules (preceding special characters with \
when included in a string) will be necessary.
var myStr = 'this.is.a.test';_x000D_
var reStr = '\\.';_x000D_
var newStr = myStr.replace(new RegExp(reStr, 'g'), '-');_x000D_
_x000D_
console.log( newStr ); // "this-is-a-test"
_x000D_
The shortest and easiest answer is: you shouldn't vertically center things in webpages. HTML and CSS simply are not created with that in mind. They are text formatting languages, not user interface design languages.
That said, this is the best way I can think of. However, this will NOT WORK in Internet Explorer 7 and below!

height: 100%;
width: 100%;
display: table;
}
#tableContainer-2 {
vertical-align: middle;
display: table-cell;
height: 100%;
}
#myTable {
margin: 0 auto;
}
</style>
<div id="tableContainer-1">
<div id="tableContainer-2">

Check tis article on Partial Key Verification which covers the following requirements:
License keys must be easy enough to type in.
We must be able to blacklist (revoke) a license key in the case of chargebacks or purchases with stolen credit cards.
No “phoning home” to test keys. Although this practice is becoming more and more prevalent, I still do not appreciate it as a user, so will not ask my users to put up with it.
It should not be possible for a cracker to disassemble our released application and produce a working “keygen” from it. This means that our application will not fully test a key for verification. Only some of the key is to be tested. Further, each release of the application should test a different portion of the key, so that a phony key based on an earlier release will not work on a later release of our software.
Important: it should not be possible for a legitimate user to accidentally type in an invalid key that will appear to work but fail on a future version due to a typographical error.

What is the URL format used by jTDS?
The URL format for jTDS is:
jdbc:jtds:<server_type>://<server>[:<port>][/<database>][;<property>=<value>[;...]]
... domain Specifies the Windows domain to authenticate in. If present and the user name and password are provided, jTDS uses Windows (NTLM) authentication instead of the usual SQL Server authentication (i.e. the user and password provided are the domain user and password). This allows non-Windows clients to log in to servers which are only configured to accept Windows authentication.
If the domain parameter is present but no user name and password are provided, jTDS uses its native Single-Sign-On library and logs in with the logged Windows user's credentials (for this to work one would obviously need to be on Windows, logged into a domain, and also have the SSO library installed -- consult README.SSO in the distribution on how to do this).
The official tutorial discusses deploying an app to production. One option is to use Waitress, a production WSGI server. Other servers include Gunicorn and uWSGI.
When running publicly rather than in development, you should not use the built-in development server (
flask run
). The development server is provided by Werkzeug for convenience, but is not designed to be particularly efficient, stable, or secure.Instead, use a production WSGI server. For example, to use Waitress, first install it in the virtual environment:
$ pip install waitress
You need to tell Waitress about your application, but it doesn’t use
FLASK_APP
like flask run does. You need to tell it to import and call the application factory to get an application object.$ waitress-serve --call 'flaskr:create_app' Serving on http://0.0.0.0:8080
Or you can use waitress.serve()
in the code instead of using the CLI command.
from flask import Flask
app = Flask(__name__)
@app.route("/")
def index():
return "<h1>Hello!</h1>"
if __name__ == "__main__":
from waitress import serve
serve(app, host="0.0.0.0", port=8080)
$ python hello.py

I think you will have to have 2 routes. If you look at line 331 of the connect router the * in a path is replaced with .+ so will match 1 or more characters.
https://github.com/senchalabs/connect/blob/master/lib/middleware/router.js
If you have 2 routes that perform the same action you can do the following to keep it DRY.
var express = require("express"),
app = express.createServer();
function fooRoute(req, res, next) {
res.end("Foo Route\n");
}
app.get("/foo*", fooRoute);
app.get("/foo", fooRoute);
app.listen(3000);
It is weird that no one has suggested the OOP way:
$date = new \DateTime(); //now
$date->add(new \DateInterval('PT3600S'));//add 3600s / 1 hour
OR
$date = new \DateTime(); //now
$date->add(new \DateInterval('PT60M'));//add 60 min / 1 hour
OR
$date = new \DateTime(); //now
$date->add(new \DateInterval('PT1H'));//add 1 hour
Extract it in string with format:
var_dump($date->format('Y-m-d H:i:s'));
I hope it helps
Just a shot in the dark(since you did not share the compiler
initialization code with us): the way you retrieve the compiler
causes the issue. Point your JRE to be inside the JDK as unlike jdk, jre does not provide any tools hence, results in NPE

Using the JOIN syntax allows you to more easily comment out the join as its all included on one line. This can be useful if you are debugging a complex query
As everyone else says, they are functionally the same, however the JOIN is more clear of a statement of intent. It therefore may help the query optimiser either in current oracle versions in certain cases (I have no idea if it does), it may help the query optimiser in future versions of Oracle (no-one has any idea), or it may help if you change database supplier.
Anytime you're tempted to pass a collection (or pointer or reference to one) to a function, ask yourself whether you couldn't pass a couple of iterators instead. Chances are that by doing so, you'll make your function more versatile (e.g., make it trivial to work with data in another type of container when/if needed).
In this case, of course, there's not much point since the standard library already has perfectly good binary searching, but when/if you write something that's not already there, being able to use it on different types of containers is often quite handy.
$date = DateTime::createFromFormat("Y-m-d", "2068-06-15");
echo $date->format("Y");
The DateTime class does not use an unix timestamp internally, so it han handle dates before 1970 or after 2038.
while(i<10){
$('#Postsoutput').prepend('<div id="first'+i+'">'+i+'</div>');
/* get the dynamic Div*/
$('#first'+i).hide(1000);
$('#first'+i).show(1000);
i++;
}
Working code from my sources:
HTML WORLD
<select name="select_from" disabled>...</select>
JS WORLD
var from = jQuery('select[name=select_from]');
//add disabled
from.attr('disabled', 'disabled');
//remove it
from.removeAttr("disabled");
It's also possible to emulate innerText
behavior in other browsers:
if (((typeof window.HTMLElement) !== "undefined") && ((typeof HTMLElement.prototype.__defineGetter__) !== "undefined")) {
HTMLElement.prototype.__defineGetter__("innerText", function () {
if (this.textContent) {
return this.textContent;
} else {
var r = this.ownerDocument.createRange();
r.selectNodeContents(this);
return r.toString();
}
});
HTMLElement.prototype.__defineSetter__("innerText", function (str) {
if (this.textContent) {
this.textContent = str;
} else {
this.innerHTML = str.replace(/&/g, '&').replace(/>/g, '>').replace(/</g, '<').replace(/\n/g, "<br />\n");
}
});
}
Use a good XSD Schema to create a set of classes with xsd.exe and use an XmlSerializer
to create a object tree out of your XML and vice versa. If you have few restrictions on your model, you could even try to create a direct mapping between you model classes and the XML with the Xml*Attributes.
There is an introductory article about XML Serialisation on MSDN.
Performance tip: Constructing an XmlSerializer
is expensive. Keep a reference to your XmlSerializer
instance if you intend to parse/write multiple XML files.
Study up on multidimensional arrays. This question might help.
function array2xml(array $data, SimpleXMLElement $object = null, $oldNodeName = 'item')
{
if (is_null($object)) $object = new SimpleXMLElement('<root/>');
$isNumbered = true;
$idx = 0;
foreach ($data as $key => $x)
if (is_string($key) || ($idx++ != $key + 0))
$isNumbered = false;
foreach ($data as $key => $value)
{
$attribute = preg_match('/^[0-9]/', $key . '') ? $key : null;
$key = (is_string($key) && !preg_match('/^[0-9]/', $key . '')) ? $key : preg_replace('/s$/', '', $oldNodeName);
if (is_array($value))
{
$new_object = $object->addChild($key);
if (!$isNumbered && !is_null($attribute)) $new_object->addAttribute('id', $attribute);
array2xml($value, $new_object, $key);
}
else
{
if (is_bool($value)) $value = $value ? 'true' : 'false';
$node = $object->addChild($key, htmlspecialchars($value));
if (!$isNumbered && !is_null($attribute) && !isset($node->attributes()->id))
$node->addAttribute('id', $attribute);
}
}
return $object;
}
This function returns for example a list of <obj>...</obj><obj>...</obj> XML tags for numeric indexes.
Input:
array(
'people' => array(
'dog',
'cat',
'life' => array(
'gum',
'shoe',
),
'fish',
),
array('yeah'),
)
Output:
<root>
<people>
<people>dog</people>
<people>cat</people>
<life>
<life>gum</life>
<life>shoe</life>
</life>
<people>fish</people>
<people>
<people>yeah</people>
</people>
</people>
</root>
This should satisfy all common needs. Maybe you may change the 3rd line to:
$key = is_string($key) ? $key : $oldNodeName . '_' . $key;
or if you are working with plurals ending with s:
$key = is_string($key) ? $key : preg_replace('/s$/', '', $oldNodeName);
From php docs:
For SELECT, SHOW, DESCRIBE, EXPLAIN and other statements returning resultset, mysql_query() returns a resource on success, or FALSE on error.
For other type of SQL statements, INSERT, UPDATE, DELETE, DROP, etc, mysql_query() returns TRUE on success or FALSE on error.
The returned result resource should be passed to mysql_fetch_array(), and other functions for dealing with result tables, to access the returned data.
spring boot allows us to write different profiles to write for different environments, for example we can have separate properties files for production, qa and local environments
application-local.properties file with configurations according to my local machine is
spring.profiles.active=local
spring.data.mongodb.host=localhost
spring.data.mongodb.port=27017
spring.data.mongodb.database=users
spring.data.mongodb.username=humble_freak
spring.data.mongodb.password=freakone
spring.rabbitmq.host=localhost
spring.rabbitmq.username=guest
spring.rabbitmq.password=guest
spring.rabbitmq.port=5672
rabbitmq.publish=true
Similarly, we can write application-prod.properties and application-qa.properties as many properties files as we want
then write some scripts to start the application for different environments, for e.g.
mvn spring-boot:run -Drun.profiles=local
mvn spring-boot:run -Drun.profiles=qa
mvn spring-boot:run -Drun.profiles=prod
The auto keyword gets the type from the expression on the right of =. Therefore it will work with any type, the only requirement is to initialize the auto variable when declaring it so that the compiler can deduce the type.
Examples:
auto a = 0.0f; // a is float
auto b = std::vector<int>(); // b is std::vector<int>()
MyType foo() { return MyType(); }
auto c = foo(); // c is MyType
Here is an example of accessing the ith
index of a std::vector
using an std::iterator
within a loop which does not require incrementing two iterators.
std::vector<std::string> strs = {"sigma" "alpha", "beta", "rho", "nova"};
int nth = 2;
std::vector<std::string>::iterator it;
for(it = strs.begin(); it != strs.end(); it++) {
int ith = it - strs.begin();
if(ith == nth) {
printf("Iterator within a for-loop: strs[%d] = %s\n", ith, (*it).c_str());
}
}
Without a for-loop
it = strs.begin() + nth;
printf("Iterator without a for-loop: strs[%d] = %s\n", nth, (*it).c_str());
and using at
method:
printf("Using at position: strs[%d] = %s\n", nth, strs.at(nth).c_str());
getSupportActionBar().setDisplayShowTitleEnabled(false);
getSupportActionBar().hide();
hope this will help
Daniel LeCheminant's code didn't work for me after converting it from CoffeeScript to JavaScript (js2coffee). It kept bombing out on the _.defer()
line.
I assumed this was something to do with jQuery deferreds, so I changed it to $.Deferred()
and it's working now. I tested it in Internet Explorer 11, Firefox 35, and Chrome 39 with jQuery 2.1.1. The usage is the same as described in Daniel's post.

If you are trying to call another exe
file inside the bat
-file.
You must use SET Path
inside the bat
-file that you are calling.
set Path should point into the directory there the exe
-file is located:
set PATH=C:\;C:\DOS {Sets C:\;C:\DOS as the current search path.}
If someone comes here looking for a way to add options with data properties
Using attr

var option = $('<option>', { value: 'the_value', text: 'some text' }).data('misc', 'misc-value);
I'm using jQuery UI 1.8.13 and the following configuration works as I need:
var buttonsConfig = [

"class": "ok",
click: function() {

},
{
text: "Annulla",
"class": "cancel",
click: function() {

];
$("#foo").dialog({
buttons: buttonsConfig
// ...
ps: remember to wrap "class" with quotes because it's a reserved word in js!
Best option is to use the '?' argument for the method. This way DBMS_MVIEW will choose the best way to refresh, so it'll do the fastest refresh it can for you. , and won't fail if you try something like method=>'f' when you actually need a complete refresh. :-)
from the SQL*Plus prompt:
EXEC DBMS_MVIEW.REFRESH('my_schema.my_mview', method => '?');
This is impossible to do at runtime.
There are various memory profilers that display object size, though.
EDIT: You could write a second program that profiles the first one using the CLR Profiling API and communicates with it through remoting or something.
def rot13(s):
lower_chars = ''.join(chr(c) for c in range (97,123)) #ASCII a-z
upper_chars = ''.join(chr(c) for c in range (65,91)) #ASCII A-Z
lower_encode = lower_chars[13:] + lower_chars[:13] #shift 13 bytes
upper_encode = upper_chars[13:] + upper_chars[:13] #shift 13 bytes
output = "" #outputstring
for c in s:
if c in lower_chars:
output = output + lower_encode[lower_chars.find(c)]
elif c in upper_chars:
output = output + upper_encode[upper_chars.find(c)]
else:
output = output + c
return output
Another solution with shifting. Maybe this code helps other people to understand rot13 better. Haven't tested it completely.
You can use lodash sortBy (https://lodash.com/docs/4.17.4#sortBy).
Your code could be like:
const myArray = [
{
"id":25,
"name":"Anakin Skywalker",
"createdAt":"2017-04-12T12:48:55.000Z",
"updatedAt":"2017-04-12T12:48:55.000Z"
},
{
"id":1,
"name":"Luke Skywalker",
"createdAt":"2017-04-12T11:25:03.000Z",
"updatedAt":"2017-04-12T11:25:03.000Z"
}
]
const myOrderedArray = _.sortBy(myArray, o => o.name)

The var
keyword in C#'s main benefit is to enhance readability, not functionality. Technically, the var
keywords allows for some other unlocks (e.g. use of anonymous objects), but that seems to be outside the scope of this question. Every variable declared with the var
keyword has a type. For instance, you'll find that the following code outputs "String".
var myString = "";
Console.Write(myString.GetType().Name);
Furthermore, the code above is equivalent to:
String myString = "";
Console.Write(myString.GetType().Name);
The var
keyword is simply C#'s way of saying "I can figure out the type for myString
from the context, so don't worry about specifying the type."
var myVariable = (MyType)null
or MyType myVariable = null
should work because you are giving the C# compiler context to figure out what type myVariable
should will be.

Use adb kill-server
. It should helps.
or
adb -s emulator-5554 emu kill
, where emulator-5554
is the emulator name.
For Ubuntu users I found a good command to stop all running emulators (Thanks to @uwe)
adb devices | grep emulator | cut -f1 | while read line; do adb -s $line emu kill; done
Yes, people use these terms interchangeably with regard to MySQL. Though oftentimes you will hear people inappropriately refer to the entire database server as the database.

UPDATE: I'm not sure this is a good example anymore, it hasn't been updated in 2-3 years.
How about passing the controller function with bidirectional binding? Then you can use it in the directive exactly the same way as in a regular template (I stripped irrelevant parts for simplicity):
<div ng-controller="testCtrl">
<!-- pass the function with no arguments -->
<test color1="color1" update-fn="updateFn"></test>
</div>
<script>
angular.module('dr', [])
.controller("testCtrl", function($scope) {
$scope.updateFn = function(msg) {
alert(msg);
}
})
.directive('test', function() {
return {
scope: {
updateFn: '=' // '=' bidirectional binding
},
template: "<button ng-click='updateFn(1337)'>Click</button>"
}
});
</script>
I landed at this question, because I tried the method above befire, but somehow it didn't work. Now it works perfectly.
First remove position:absolute
of div#iframe-wrapper iframe
, Remove position:fixed
and all other css from div#iframe-wrapper
Then apply this css,
div#iframe-wrapper {
width: 200px;
height: 400px;
margin: 0 auto;
}
Now Here is a different approach to the problem:
Right click on the project and select the 'Unload Project' option. You will notice you project becomes unavailable.
Right click on the unavailable project and select the 'Edit' option.
Scroll down to the ' < ItemGroup > ' tag that contains all the resource tags.
Now go to the reference that has been displayed on the error list, you will notice it it uses a single tag (i.e. < Reference Include="assemble_name_here, Version=0.0.0.0, Culture=neutral" / >
).
Change that to look as follows:
.
<Reference Include="assemble_name_here, Version=1.0.0.0, Culture=neutral, processorArchitecture=MSIL" >
< Private > True < / Private >
< HintPath > path_here\assemble_name_here.dll < / HintPath >
< / Reference >
I faced this same problem, and I came up with a solution that didn't invole using the ProgressDialog and I get faster results.
What I did was create a layout that has a ProgressBar in it.
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
<ProgressBar
android:id="@+id/progressImage"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerInParent="true"
/>
</RelativeLayout>
Then in the onCreate method do the following
public void onCreate(Bundle icicle) {
super.onCreate(icicle);
setContentView(R.layout.progress);
}
Then do the long task in a thread, and when that's finished have a Runnable set the content view to the real layout you want to use for this activity.
For example:
mHandler.post(new Runnable(){
public void run() {
setContentView(R.layout.my_layout);
}
});
This is what I did, and I've found that it runs faster than showing the ProgressDialog and it's less intrusive and has a better look in my opinion.
However, if you're wanting to use the ProgressDialog, then this answer isn't for you.
I have found it easiest to use a graphical interface on windows (I recommend mobaXTerm it has ssh, scp, ftp, remote desktop, and many more) but if you are set on command line I would recommend cd'ing into the directory with the source folder then
scp -r yourFolder username@server:/path/to/dir
the -r
indicates recursive to be used on directories
You can still use map
if you can afford to create a makeshift array:
{
new Array(this.props.level).fill(0).map((_, index) => (
<span className='indent' key={index}></span>
))
}
This works because new Array(n).fill(x)
creates an array of size n
filled with x
, which can then aid map
.
200,300, 400, 500 are all very generic. If you want generic, 400 is OK.
422 is used by an increasing number of APIs, and is even used by Rails out of the box.
No matter which status code you pick for your API, someone will disagree. But I prefer 422 because I think of '400 + text status' as too generic. Also, you aren't taking advantage of a JSON-ready parser; in contrast, a 422 with a JSON response is very explicit, and a great deal of error information can be conveyed.
Speaking of JSON response, I tend to standardize on the Rails error response for this case, which is:
{
"errors" :
{
"arg1" : ["error msg 1", "error msg 2", ...]
"arg2" : ["error msg 1", "error msg 2", ...]
}
}
This format is perfect for form validation, which I consider the most complex case to support in terms of 'error reporting richness'. If your error structure is this, it will likely handle all your error reporting needs.
Use this line of code in your css
border: 1px solid #000 !important;
or if you want border only in left and right side of container then use:
border-right: 1px solid #000 !important;
border-left: 1px solid #000 !important;
TL;DR: use px
.
First, it's extremely important to know that per spec, the CSS px
unit does not equal one physical display pixel. This has always been true – even in the 1996 CSS 1 spec.
CSS defines the reference pixel, which measures the size of a pixel on a 96 dpi display. On a display that has a dpi substantially different than 96dpi (like Retina displays), the user agent rescales the px
unit so that its size matches that of a reference pixel. In other words, this rescaling is exactly why 1 CSS pixel equals 2 physical Retina display pixels.
That said, up until 2010 (and the mobile zoom situation notwithstanding), the px
almost always did equal one physical pixel, because all widely available displays were around 96dpi.
Sizes specified in em
s are relative to the parent element. This leads to the em
's "compounding problem" where nested elements get progressively larger or smaller. For example:
body { font-size:20px; }
div { font-size:0.5em; }
Gives us:
<body> - 20px
<div> - 10px
<div> - 5px
<div> - 2.5px
<div> - 1.25px
The CSS3 rem
, which is always relative only to the root html
element, is now supported on 96% of all browsers in use.
I think everyone agrees that it's good to design your pages to be accommodating to everyone, and to make consideration for the visually impaired. One such consideration (but not the only one!) is allowing users to make the text of your site bigger, so that it's easier to read.
In the beginning, the only way to provide users a way to scale text size was by using relative size units (such as em
s). This is because the browser's font size menu simply changed the root font size. Thus, if you specified font sizes in px
, they wouldn't scale when changing the browser's font size option.
Modern browsers (and even the not-so-modern IE7) all changed the default scaling method to simply zooming in on everything, including images and box sizes. Essentially, they make the reference pixel larger or smaller.
Yes, someone could still change their browser default stylesheet to tweak the default font size (the equivalent of the old-style font size option), but that's a very esoteric way of going about it and I'd wager nobody1 does it. (In Chrome, it's buried under the advanced settings, Web content, Font Sizes. In IE9, it's even more hidden. You have to press Alt, and go to View, Text Size.) It's much easier to just select the Zoom option in the browser's main menu (or use Ctrl++/-/mouse wheel).
1 - within statistical error, naturally
If we assume most users scale pages using the zoom option, I find relative units mostly irrelevant. It's much easier to develop your page when everything is specified in the same unit (images are all dealt with in pixels), and you don't have to worry about compounding. ("I was told there would be no math" – there's dealing with having to calculate what 1.5em actually works out to.)
One other potential problem of using only relative units for font sizes is that user-resized fonts may break assumptions your layout makes. For example, this might lead to text getting clipped or running too long. If you use absolute units, you don't have to worry about unexpected font sizes from breaking your layout.
So my answer is use pixel units. I use px
for everything. Of course, your situation may vary, and if you must support IE6 (may the gods of the RFCs have mercy on you), you'll have to use em
s anyway.
With Lamma it looks like this in Java:
for (Date d: Dates.from(2014, 6, 29).to(2014, 7, 1).build()) {
System.out.println(d);
}
and the output is:
Date(2014,6,29)
Date(2014,6,30)
Date(2014,7,1)
Simply put, Git is a version control system that lets you manage and keep track of your source code history. GitHub is a cloud-based hosting service that lets you manage Git repositories. If you have open-source projects that use Git, then GitHub is designed to help you better manage them.
At this point, the simplest way is to just truncate the last two digits of the year. For credit cards, having a date in the past is unnecessary so Y2K has no meaning. The same applies for if somehow your code is still running in 90+ years.
I'd go further and say that instead of using a drop down list, let the user type in the year themselves. This is a common way of doing it and most users can handle it.
On alternativ answer is this.
if you have and array like this: var contacts = [bob, mary];
and you want to put another array in this array, you can do that in this way:
Declare the function constructor
function add (firstName,lastName,email,phoneNumber) {
this.firstName = firstName;
this.lastName = lastName;
this.email = email;
this.phoneNumber = phoneNumber;
}
make the object from the function:
var add1 = new add("Alba","Fas","[email protected]","[098] 654365364");
and add the object in to the array:
contacts[contacts.length] = add1;
i'm gunna post this solution as well, since i had this problem but the other solutions did not work for my situation...
i think to properly simulate the background-size:cover;
css property on an element instead of an elements background-image property, you'd have to compare the images aspect ratio to the current windows aspect ratio, so no matter what size (and also in case the image is taller than wider) the window is the element is filling the window (and also centering it, though i don't know if that was a requirement)....
using an image, just for simplicity's sake, i'm sure a video element would work fine too.
first get the elements aspect ratio (once it's loaded), then attach the window resize handler, trigger it once for initial sizing:
var img = document.getElementById( "background-picture" ),
imgAspectRatio;
img.onload = function() {
// get images aspect ratio
imgAspectRatio = this.height / this.width;
// attach resize event and fire it once
window.onresize = resizeBackground;
window.onresize();
}
then in your resize handler you should first determine whether to fill width or fill height by comparing the window's current aspect ratio to the image's original aspect ratio.
function resizeBackground( evt ) {
// get window size and aspect ratio
var windowWidth = window.innerWidth,
windowHeight = window.innerHeight;
windowAspectRatio = windowHeight / windowWidth;
//compare window ratio to image ratio so you know which way the image should fill
if ( windowAspectRatio < imgAspectRatio ) {
// we are fill width
img.style.width = windowWidth + "px";
// and applying the correct aspect to the height now
img.style.height = (windowWidth * imgAspectRatio) + "px";
// this can be margin if your element is not positioned relatively, absolutely or fixed
// make sure image is always centered
img.style.left = "0px";
img.style.top = (windowHeight - (windowWidth * imgAspectRatio)) / 2 + "px";
} else { // same thing as above but filling height instead
img.style.height = windowHeight + "px";
img.style.width = (windowHeight / imgAspectRatio) + "px";
img.style.left = (windowWidth - (windowHeight / imgAspectRatio)) / 2 + "px";
img.style.top = "0px";
}
}
When i tried the difference between same time stamp it gave 0 Days 5 Hours 30 Minutes
so to get it exactly i have subtracted 5 hours and 30 min
function get_time_diff( datetime )
{
var datetime = typeof datetime !== 'undefined' ? datetime : "2014-01-01 01:02:03.123456";
var datetime = new Date(datetime).getTime();
var now = new Date().getTime();
if( isNaN(datetime) )
{
return "";
}
console.log( datetime + " " + now);
if (datetime < now) {
var milisec_diff = now - datetime;
}else{
var milisec_diff = datetime - now;
}
var days = Math.floor(milisec_diff / 1000 / 60 / (60 * 24));
var date_diff = new Date( milisec_diff );
return days + "d "+ (date_diff.getHours() - 5) + "h " + (date_diff.getMinutes() - 30) + "m";
}
By using a combination of JQuery's .trigger()
and native Javascripts's .reset()
all form elements can be reset to blank state.
$(".reset").click(function(){
$("#<form_id>").trigger("reset");
});
Replace <form_id>
with id of form to reset.
The correct syntax for the above statement is:
if (defined?(var)).nil? # will now return true or false
print "var is not defined\n".color(:red)
else
print "var is defined\n".color(:green)
end
substituting (var
) with your variable. This syntax will return a true/false value for evaluation in the if statement.
(<HTMLInputElement>document.getElementById('loginInput')).value = '123';
Angular cannot take HTML elements directly thereby you need to specify the element type by binding the above generic to it.
UPDATE::
This can also be done using ViewChild with #localvariable as shown here, as mentioned in here
<textarea #someVar id="tasknote"

socket.on('connection', function (client) {
var ip_address = client.connection.remoteAddress;
}
You could also be more restrictive in removing disallowed characters. The following regex would remove all characters that are not letters, digits or underscores:
$FileName = preg_replace('/[^\w]/', '', $UserInput);
You might want to do this to ensure maximum compatibility for filenames across different operating systems.
If you want to call a bash script using python, here is a simple method to load a file from a folder in S3 bucket to a local folder (in a Linux machine) :
import boto3
import subprocess
import os
###TOEDIT###
my_bucket_name = "your_my_bucket_name"
bucket_folder_name = "your_bucket_folder_name"
local_folder_path = "your_local_folder_path"
###TOEDIT###
# 1.Load thes list of files existing in the bucket folder
FILES_NAMES = []
s3 = boto3.resource('s3')
my_bucket = s3.Bucket('{}'.format(my_bucket_name))
for object_summary in my_bucket.objects.filter(Prefix="{}/".format(bucket_folder_name)):
# print(object_summary.key)
FILES_NAMES.append(object_summary.key)
# 2.List only new files that do not exist in local folder (to not copy everything!)
new_filenames = list(set(FILES_NAMES )-set(os.listdir(local_folder_path)))
# 3.Time to load files in your destination folder
for new_filename in new_filenames:
upload_S3files_CMD = """aws s3 cp s3://{}/{}/{} {}""".format(my_bucket_name,bucket_folder_name,new_filename ,local_folder_path)
subprocess_call = subprocess.call([upload_S3files_CMD], shell=True)
if subprocess_call != 0:
print("ALERT: loading files not working correctly, please re-check new loaded files")
You are consuming a line at, which is discarded
while((str=input.readLine())!=null && str.length()!=0)
and reading a bigint at
BigInteger n = new BigInteger(input.readLine());
so try getting the bigint from string which is read as
BigInteger n = new BigInteger(str);
Constructor used: BigInteger(String val)
Aslo change while((str=input.readLine())!=null && str.length()!=0)
to
while((str=input.readLine())!=null)
see related post string to bigint
readLine()
Returns:
A String containing the contents of the line, not including any line-termination characters, or null if the end of the stream has been reached

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

Mongoose 4.6.0+:
mongoose.connect('mongodb://localhost/mydb')
mongoose.connection.once('connected', () => {
mongoose.connection.db.dropDatabase();
});
Passing a callback to connect won't work anymore:

If your class inherits from Thread, you can use methods getName
and setName
to name each thread. Otherwise you could just add a name
field to MyTask
, and initialize it in your constructor.
Even if this is already answered (1 year ago) you could also let the fields be calculated automatically.
The HTML
<tr>
<td><input type="text" value="" ></td>
<td><input type="text" class="class_name" placeholder="bla bla"/></td>
</tr>
<tr>
<td><input type="text" value="" ></td>
<td><input type="text" class="class_name" placeholder="bla bla."/></td>
</tr>
The script
$(document).ready(function(){
$(".class_name").each(function(){
$(this).keyup(function(){
calculateSum()
;})
;})
;}
);
function calculateSum(){
var sum=0;
$(".class_name").each(function(){
if(!isNaN(this.value) && this.value.length!=0){
sum+=parseFloat(this.value);
}
else if(isNaN(this.value)) {
alert("Maybe an alert if they type , instead of .");
}
}
);
$("#sum").html(sum.toFixed(2));
}
Just simple as this

"Copy on write" means more or less what it sounds like: everyone has a single shared copy of the same data until it's written, and then a copy is made. Usually, copy-on-write is used to resolve concurrency sorts of problems. In ZFS, for example, data blocks on disk are allocated copy-on-write; as long as there are no changes, you keep the original blocks; a change changed only the affected blocks. This means the minimum number of new blocks are allocated.
These changes are also usually implemented to be transactional, ie, they have the ACID properties. This eliminates some concurrency issues, because then you're guaranteed that all updates are atomic.
if (strpos($string, $word) === FALSE) {
... not found ...
}
Note that strpos()
is case sensitive, if you want a case-insensitive search, use stripos()
instead.
Also note the ===
, forcing a strict equality test. strpos CAN return a valid 0
if the 'needle' string is at the start of the 'haystack'. By forcing a check for an actual boolean false (aka 0), you eliminate that false positive.

If multiple criteria use countifs
=countifs(A1:A10,">""",B1:B10,">""")
The " >"" "
looks at the greater than being empty. This formula looks for two criteria and neither column can be empty on the same row for it to count. If just counting one column do this with the one criteria (i.e. Use everything before B1:B10
not including the comma)
select count(*)

where DATEPART(YEAR, ARR_DATE) = '2012' AND DATEPART(MONTH, ARR_DATE) = '01'
