Just a note for reference: I was trying to do shorthand like so:
background: url('../images/sprite.png') -312px -234px / 355px auto no-repeat;
but iPhone Safari browsers weren't showing the image properly with a fixed position element. I didn't check with a non-fixed, because I'm lazy. I had to switch the css to what's below, being careful to put background-size after the background property. If you do them in reverse, the background reverts the background-size to the original size of the image. So generally I would avoid using the shorthand to set background-size.
background: url('../images/sprite.png') -312px -234px no-repeat;
background-size: 355px auto;

Take a look at svnmerge.py. It's command-line, can't be invoked by TortoiseSVN, but it's more powerful. From the FAQ:
Traditional subversion will let you merge changes, but it doesn't "remember" what you've already merged. It also doesn't provide a convenient way to exclude a change set from being merged. svnmerge.py automates some of the work, and simplifies it. Svnmerge also creates a commit message with the log messages from all of the things it merged.
I know this has been answered, but TypeScript introduced type guards: https://www.typescriptlang.org/docs/handbook/advanced-types.html#typeof-type-guards
If you have a type like: Object[] | string[]
and what to do something conditionally based on what type it is - you can use this type guarding:
function isStringArray(value: any): value is string[] {
if (value instanceof Array) {
value.forEach(function(item) { // maybe only check first value?
if (typeof item !== 'string') {
return false
}
})
return true
}
return false
}
function join<T>(value: string[] | T[]) {
if (isStringArray(value)) {
return value.join(',') // value is string[] here
} else {
return value.map((x) => x.toString()).join(',') // value is T[] here
}
}
There is an issue with an empty array being typed as string[]
, but that might be okay
You can also use Object.assign
from ECMAScript 2015
. It also allows you to add nested attributes at once. E.g.:
const myObject = {};
Object.assign(myObject, {
firstNewAttribute: {
nestedAttribute: 'woohoo!'
}
});
Ps: This will not override the existing object with the assigned attributes. Instead they'll be added. However if you assign a value to an existing attribute then it would be overridden.
None of these fixes were working for me until I found out that RefererNotAllowedMapError
can be caused by not having a billing account linked to the project. So make sure to activate your free trial or whatever.
Does this do what you want?
print range(0, (m+1)*n, n)[1:]
For m=5, n=20
[20, 40, 60, 80, 100]
Or better yet,
>>> print range(n, (m+1)*n, n)
[20, 40, 60, 80, 100]
For Python3+
>>> print(list(range(n, (m+1)*n, n)))
[20, 40, 60, 80, 100]
Change the button to
<button id="search">Search</button>
and add the following script
var url = '@Url.Action("DisplaySearchResults", "Search")';
$('#search').click(function() {
var keyWord = $('#Keyword').val();
$('#searchResults').load(url, { searchText: keyWord });
})
and modify the controller method to accept the search text
public ActionResult DisplaySearchResults(string searchText)
{
var model = // build list based on parameter searchText
return PartialView("SearchResults", model);
}
The jQuery .load
method calls your controller method, passing the value of the search text and updates the contents of the <div>
with the partial view.
Side note: The use of a <form>
tag and @Html.ValidationSummary()
and @Html.ValidationMessageFor()
are probably not necessary here. Your never returning the Index
view so ValidationSummary
makes no sense and I assume you want a null
search text to return all results, and in any case you do not have any validation attributes for property Keyword
so there is nothing to validate.
Edit
Based on OP's comments that SearchCriterionModel
will contain multiple properties with validation attributes, then the approach would be to include a submit button and handle the forms .submit()
event
<input type="submit" value="Search" />
var url = '@Url.Action("DisplaySearchResults", "Search")';
$('form').submit(function() {
if (!$(this).valid()) {
return false; // prevent the ajax call if validation errors
}
var form = $(this).serialize();
$('#searchResults').load(url, form);
return false; // prevent the default submit action
})
and the controller method would be
public ActionResult DisplaySearchResults(SearchCriterionModel criteria)
{
var model = // build list based on the properties of criteria
return PartialView("SearchResults", model);
}
If you are using a custom binding, you can set the values like this:
<customBinding>
<binding name="x">
<httpsTransport maxBufferSize="2147483647" maxReceivedMessageSize="2147483647" />
</binding>
</customBinding>
There are many metrics out there for evaluating whether two images look like/how much they look like.
I will not go into any code here, because I think it should be a scientific problem, other than a technical problem.
Generally, the question is related to human's perception on images, so each algorithm has its support on human visual system traits.
Classic approaches are:
Visible differences predictor: an algorithm for the assessment of image fidelity (https://www.spiedigitallibrary.org/conference-proceedings-of-spie/1666/0000/Visible-differences-predictor--an-algorithm-for-the-assessment-of/10.1117/12.135952.short?SSO=1)
Image Quality Assessment: From Error Visibility to Structural Similarity (http://www.cns.nyu.edu/pub/lcv/wang03-reprint.pdf)
FSIM: A Feature Similarity Index for Image Quality Assessment (https://www4.comp.polyu.edu.hk/~cslzhang/IQA/TIP_IQA_FSIM.pdf)
Among them, SSIM (Image Quality Assessment: From Error Visibility to Structural Similarity ) is the easiest to calculate and its overhead is also small, as reported in another paper "Image Quality Assessment Based on Gradient Similarity" (https://www.semanticscholar.org/paper/Image-Quality-Assessment-Based-on-Gradient-Liu-Lin/2b819bef80c02d5d4cb56f27b202535e119df988).
There are many more other approaches. Take a look at Google Scholar and search for something like "visual difference", "image quality assessment", etc, if you are interested/really care about the art.

This is an excellent Stack Overflow question, and the answers have been very instructive, such that I was able to resolve an annoying problem I ran into recently.
The organization that I work for uses Atlassian's BitBucket
product (not Github), essentially their version of GitHub so that repositories can be secured completely on premise. I was running into a similar problem as @coordinate, in that my password was required for a new repository I checked out. My credentials had been saved globally for all BitBucket
projects, so I'm not sure what prompted the loss of credentials.
In short, I was able to enter the following GIT command (supplying only my username), which then prompted Git's Credential Manager to prompt me for the password, which I was then able to save.
git clone https://[email protected]/git/[organization]/[team]/[repository.git]
NOTE: the bracketed directory sub-paths simply refer to internal references, and will vary for you!
Use this code:
// Get current size of heap in bytes
long heapSize = Runtime.getRuntime().totalMemory();
// Get maximum size of heap in bytes. The heap cannot grow beyond this size.// Any attempt will result in an OutOfMemoryException.
long heapMaxSize = Runtime.getRuntime().maxMemory();
// Get amount of free memory within the heap in bytes. This size will increase // after garbage collection and decrease as new objects are created.
long heapFreeSize = Runtime.getRuntime().freeMemory();
It was useful to me to know it.
[UPDATE] As of ~June 2017, Docker for Mac takes care of all the annoying parts of this where you have to mess with VirtualBox. It lets you map basically everything on your local host using the /private
prefix. More info here. [/UPDATE]
All the current answers talk about Boot2docker. Since that's now deprecated in favor of docker-machine, this works for docker-machine:
First, ssh into the docker-machine vm and create the folder we'll be mapping to:
docker-machine ssh $MACHINE_NAME "sudo mkdir -p \"$VOL_DIR\""
Now share the folder to VirtualBox:
WORKDIR=$(basename "$VOL_DIR")
vboxmanage sharedfolder add "$MACHINE_NAME" --name "$WORKDIR" --hostpath "$VOL_DIR" --transient
Finally, ssh into the docker-machine again and mount the folder we just shared:
docker-machine ssh $MACHINE_NAME "sudo mount -t vboxsf -o uid=\"$U\",gid=\"$G\" \"$WORKDIR\" \"$VOL_DIR\""
Note: for UID and GID you can basically use whatever integers as long as they're not already taken.
This is tested as of docker-machine 0.4.1 and docker 1.8.3 on OS X El Capitan.
A compact way to find multiple strings in another list of strings is to use set.intersection. This executes much faster than list comprehension in large sets or lists.
>>> astring = ['abc','def','ghi','jkl','mno']
>>> bstring = ['def', 'jkl']
>>> a_set = set(astring) # convert list to set
>>> b_set = set(bstring)
>>> matches = a_set.intersection(b_set)
>>> matches
{'def', 'jkl'}
>>> list(matches) # if you want a list instead of a set
['def', 'jkl']
>>>
np.array()
is even more powerful than what unutbu said above.
You also could use it to convert a list of np arrays to a higher dimention array, the following is a simple example:
aArray=np.array([1,1,1])
bArray=np.array([2,2,2])
aList=[aArray, bArray]
xArray=np.array(aList)
xArray's shape is (2,3), it's a standard np array. This operation avoids a loop programming.
This isn't a very beautiful answer, but it's what I use to create zero-length vectors:
0[-1] # numeric
""[-1] # character
TRUE[-1] # logical
0L[-1] # integer
A literal is a vector of length 1, and [-1]
removes the first element (the only element in this case) from the vector, leaving a vector with zero elements.
As a bonus, if you want a single NA
of the respective type:
0[NA] # numeric
""[NA] # character
TRUE[NA] # logical
0L[NA] # integer
This is one of the most well-known examples of authors misunderstanding how :first-child
works. Introduced in CSS2, the :first-child
pseudo-class represents the very first child of its parent. That's it. There's a very common misconception that it picks up whichever child element is the first to match the conditions specified by the rest of the compound selector. Due to the way selectors work (see here for an explanation), that is simply not true.
Selectors level 3 introduces a :first-of-type
pseudo-class, which represents the first element among siblings of its element type. This answer explains, with illustrations, the difference between :first-child
and :first-of-type
. However, as with :first-child
, it does not look at any other conditions or attributes. In HTML, the element type is represented by the tag name. In the question, that type is p
.
Unfortunately, there is no similar :first-of-class
pseudo-class for matching the first child element of a given class. One workaround that Lea Verou and I came up with for this (albeit totally independently) is to first apply your desired styles to all your elements with that class:
/*
* Select all .red children of .home, including the first one,
* and give them a border.
*/
.home > .red {
border: 1px solid red;
}
... then "undo" the styles for elements with the class that come after the first one, using the general sibling combinator ~
in an overriding rule:
/*
* Select all but the first .red child of .home,
* and remove the border from the previous rule.
*/
.home > .red ~ .red {
border: none;
}
Now only the first element with class="red"
will have a border.
Here's an illustration of how the rules are applied:
<div class="home">
<span>blah</span> <!-- [1] -->
<p class="red">first</p> <!-- [2] -->
<p class="red">second</p> <!-- [3] -->
<p class="red">third</p> <!-- [3] -->
<p class="red">fourth</p> <!-- [3] -->
</div>
No rules are applied; no border is rendered.
This element does not have the class red
, so it's skipped.
Only the first rule is applied; a red border is rendered.
This element has the class red
, but it's not preceded by any elements with the class red
in its parent. Thus the second rule is not applied, only the first, and the element keeps its border.
Both rules are applied; no border is rendered.
This element has the class red
. It is also preceded by at least one other element with the class red
. Thus both rules are applied, and the second border
declaration overrides the first, thereby "undoing" it, so to speak.
As a bonus, although it was introduced in Selectors 3, the general sibling combinator is actually pretty well-supported by IE7 and newer, unlike :first-of-type
and :nth-of-type()
which are only supported by IE9 onward. If you need good browser support, you're in luck.
In fact, the fact that the sibling combinator is the only important component in this technique, and it has such amazing browser support, makes this technique very versatile — you can adapt it for filtering elements by other things, besides class selectors:
You can use this to work around :first-of-type
in IE7 and IE8, by simply supplying a type selector instead of a class selector (again, more on its incorrect usage here in a later section):
article > p {
/* Apply styles to article > p:first-of-type, which may or may not be :first-child */
}
article > p ~ p {
/* Undo the above styles for every subsequent article > p */
}
You can filter by attribute selectors or any other simple selectors instead of classes.
You can also combine this overriding technique with pseudo-elements even though pseudo-elements technically aren't simple selectors.
Note that in order for this to work, you will need to know in advance what the default styles will be for your other sibling elements so you can override the first rule. Additionally, since this involves overriding rules in CSS, you can't achieve the same thing with a single selector for use with the Selectors API, or Selenium's CSS locators.
It's worth mentioning that Selectors 4 introduces an extension to the :nth-child()
notation (originally an entirely new pseudo-class called :nth-match()
), which will allow you to use something like :nth-child(1 of .red)
in lieu of a hypothetical .red:first-of-class
. Being a relatively recent proposal, there aren't enough interoperable implementations for it to be usable in production sites yet. Hopefully this will change soon. In the meantime, the workaround I've suggested should work for most cases.
Keep in mind that this answer assumes that the question is looking for every first child element that has a given class. There is neither a pseudo-class nor even a generic CSS solution for the nth match of a complex selector across the entire document — whether a solution exists depends heavily on the document structure. jQuery provides :eq()
, :first
, :last
and more for this purpose, but note again that they function very differently from :nth-child()
et al. Using the Selectors API, you can either use document.querySelector()
to obtain the very first match:
var first = document.querySelector('.home > .red');
Or use document.querySelectorAll()
with an indexer to pick any specific match:
var redElements = document.querySelectorAll('.home > .red');
var first = redElements[0];
var second = redElements[1];
// etc
Although the .red:nth-of-type(1)
solution in the original accepted answer by Philip Daubmeier works (which was originally written by Martyn but deleted since), it does not behave the way you'd expect it to.
For example, if you only wanted to select the p
in your original markup:
<p class="red"></p>
<div class="red"></div>
... then you can't use .red:first-of-type
(equivalent to .red:nth-of-type(1)
), because each element is the first (and only) one of its type (p
and div
respectively), so both will be matched by the selector.
When the first element of a certain class is also the first of its type, the pseudo-class will work, but this happens only by coincidence. This behavior is demonstrated in Philip's answer. The moment you stick in an element of the same type before this element, the selector will fail. Taking the updated markup:
<div class="home">
<span>blah</span>
<p class="red">first</p>
<p class="red">second</p>
<p class="red">third</p>
<p class="red">fourth</p>
</div>
Applying a rule with .red:first-of-type
will work, but once you add another p
without the class:
<div class="home">
<span>blah</span>
<p>dummy</p>
<p class="red">first</p>
<p class="red">second</p>
<p class="red">third</p>
<p class="red">fourth</p>
</div>
... the selector will immediately fail, because the first .red
element is now the second p
element.
The name open addressing refers to the fact that the location ("address") of the element is not determined by its hash value. (This method is also called closed hashing).
In separate chaining, each bucket is independent, and has some sort of ADT (list, binary search trees, etc) of entries with the same index. In a good hash table, each bucket has zero or one entries, because we need operations of order O(1) for insert, search, etc.
This is a example of separate chaining using C++ with a simple hash function using mod operator (clearly, a bad hash function)
The most simple and straightforward C/C++ implementation that I found is in a link at the bottom of this page:
Web Page: http://www.barrgroup.com/Embedded-Systems/How-To/CRC-Calculation-C-Code
Code Download Link: https://barrgroup.com/code/crc.zip
It is a simple standalone implementation with one .h and one .c file. There is support for CRC32, CRC16 and CRC_CCITT thru the use of a define. Also, the code lets the user change parameter settings like the CRC polynomial, initial/final XOR value, and reflection options if you so desire.
The license is not explicitly defined ala LGPL or similar. However the site does say that they are placing the code in the public domain for any use. The actual code files also say this.
Hope it helps!
Adding this as another possible solution, because this is what fixed it in our case;
Make sure if you have multiple projects that they are using the same Entity Framework Nuget package version!.
In our case we had one project ( call if project A ) holding the EF code first context with all entities. It was this project that we were using to add migrations & update the database. However a second project ( B ) was referencing project A to make use of the context. When running this project we got the same error;
The model backing the 'MyDbContext' context has changed since the database was created. Consider using Code First Migrations to update the database (http://go.microsoft.com/fwlink/?LinkId=238269).
Yes, though you have to turn on TLS 1.2 manually at System.Net.ServicePointManager.SecurityProtocol
System.Net.ServicePointManager.SecurityProtocol = SecurityProtocolType.Tls12 | SecurityProtocolType.Tls11 | SecurityProtocolType.Tls; // comparable to modern browsers
var response = WebRequest.Create("https://www.howsmyssl.com/").GetResponse();
var body = new StreamReader(response.GetResponseStream()).ReadToEnd();
Your client is using TLS 1.2, the most modern version of the encryption protocol
Out the box, WebRequest will use TLS 1.0 or SSL 3.
Your client is using TLS 1.0, which is very old, possibly susceptible to the BEAST attack, and doesn't have the best cipher suites available on it. Additions like AES-GCM, and SHA256 to replace MD5-SHA-1 are unavailable to a TLS 1.0 client as well as many more modern cipher suites.
See an example here: http://www.cplusplus.com/reference/stl/vector/insert/ eg.:
...
vector::iterator iterator1;
iterator1= vec1.begin();
vec1.insert ( iterator1+i , vec2[i] );
// This means that at position "i" from the beginning it will insert the value from vec2 from position i
Your first approach was replacing the values from vec1[i] with the values from vec2[i]
//get dimensions
var height = $(window).height();
var width = $(window).width();
//refresh on resize
$(window).resize(function() {
location.reload(true)
});
not sure if you wanted to tinker with the dimensions of elements or actually refresh the page. so here a bunch of different things pick what you want. you can even put the height and width in the resize event if you really wanted.
Basically, this will not work out
Format("20130423014854","yyyy-MM-dd hh:mm:ss")
the format
function will only work if your string has correct format
Format (#17/04/2004#, "yyyy/mm/dd")
And you need to specify, what datatype of field [Date]
is, because I can't put this value 2013-04-23 13:48:54.0
under a General Date field (I use MS access2007
).

Thanks! to all above answers. I hope you have a .p12 file. Now, open terminal write following command. Set terminal to the path where you have put .12 file.
$ openssl pkcs12 -in yourCertifcate.p12 -out pemAPNSCert.pem -nodes
Enter Import Password: <Just enter your certificate password>
MAC verified OK
Now your .pem file is generated.
Verify .pem file First, open the .pem in a text editor to view its content. The certificate content should be in format as shown below. Make sure the pem file contains both Certificate content(from BEGIN CERTIFICATE to END CERTIFICATE) as well as Certificate Private Key (from BEGIN PRIVATE KEY to END PRIVATE KEY) :
> Bag Attributes
> friendlyName: Apple Push Services:<Bundle ID>
> localKeyID: <> subject=<>
> -----BEGIN CERTIFICATE-----
>
> <Certificate Content>
>
> -----END CERTIFICATE----- Bag Attributes
> friendlyName: <>
> localKeyID: <> Key Attributes: <No Attributes>
> -----BEGIN PRIVATE KEY-----
>
> <Certificate Private Key>
>
> -----END PRIVATE KEY-----
Also, you check the validity of the certificate by going to SSLShopper Certificate Decoder and paste the Certificate Content (from BEGIN CERTIFICATE to END CERTIFICATE) to get all the info about the certificate as shown below:

The selector returns an array of jQuery objects. If no matching elements are found, it returns an empty array. You can check the .length
of the collection returned by the selector or check whether the first array element is 'undefined'.
You can use any the following examples inside an IF statement and they all produce the same result. True, if the selector found a matching element, false otherwise.
$('#notAnElement').length > 0
$('#notAnElement').get(0) !== undefined
$('#notAnElement')[0] !== undefined
your data snippet need to be expanded a little, and it has to be this way to be proper json. notice I just include the array name attribute "item"
{"item":[
{
"id": "1",
"msg": "hi",
"tid": "2013-05-05 23:35",
"fromWho": "[email protected]"
}, {
"id": "2",
"msg": "there",
"tid": "2013-05-05 23:45",
"fromWho": "[email protected]"
}]}
your java script is simply
var objCount = json.item.length;
for ( var x=0; x < objCount ; xx++ ) {
var curitem = json.item[x];
}
Usually, string comparisons are case-insensitive. If your database is configured to case sensitive collation, you need to force to use a case insensitive one:
SELECT balance FROM people WHERE email = '[email protected]'
COLLATE SQL_Latin1_General_CP1_CI_AS
You can try this way -
ObjectAnimator.ofFloat(view, "translationX", 100f).apply {
duration = 2000
start()
}
Note - view is your view where you want animation.
Presumably, those columns are integer columns - which will be the reason as the result of the calculation will be of the same type.
e.g. if you do this:
SELECT 1 / 2
you will get 0, which is obviously not the real answer. So, convert the values to e.g. decimal and do the calculation based on that datatype instead.
e.g.
SELECT CAST(1 AS DECIMAL) / 2
gives 0.500000
This exception comes from the client, right? Please perform a forward and reverse DNS lookup of the server hostname. Your server has incorrect DNS entries. They are absolutely crucial for Kerberos. The proper place is your DNS server, in your case: domain controller. Figure out the IP address of your DNS server and contact your admin. The other option is a missing SPN, please check that too.
I am convinced that it is impossible now. It was, though.
IE7’s implementation of getClientRects did exactly what I want. Open this page in IE8, try refreshing it varying window width, and see how number of lines in the first element changes accordingly. Here’s the key lines of the javascript from that page:
var rects = elementList[i].getClientRects();
var p = document.createElement('p');
p.appendChild(document.createTextNode('\'' + elementList[i].tagName + '\' element has ' + rects.length + ' line(s).'));
Unfortunately for me, Firefox always returns one client rectangle per element, and IE8 does the same now. (Martin Honnen’s page works today because IE renders it in IE compat view; press F12 in IE8 to play with different modes.)
This is sad. It looks like once again Firefox’s literal but worthless implementation of the spec won over Microsoft’s useful one. Or do I miss a situation where new getClientRects may help a developer?
If you want to want to treat 1,2 and 2,1 as the same pair, then this will give you the unique list on MS-SQL:

FROM pairs

Several years ago I used JTidy for the same purpose:
"JTidy is a Java port of HTML Tidy, a HTML syntax checker and pretty printer. Like its non-Java cousin, JTidy can be used as a tool for cleaning up malformed and faulty HTML. In addition, JTidy provides a DOM interface to the document that is being processed, which effectively makes you able to use JTidy as a DOM parser for real-world HTML.
JTidy was written by Andy Quick, who later stepped down from the maintainer position. Now JTidy is maintained by a group of volunteers.
More information on JTidy can be found on the JTidy SourceForge project page ."
Here's another looping example. This one also contains an 'if-statement' as an example of checking to see if the entry is a 'file' (or a 'directory' for example):

Use :
norm = [float(i)/sum(raw) for i in raw]
to normalize against the sum to ensure that the sum is always 1.0 (or as close to as possible).
use
norm = [float(i)/max(raw) for i in raw]
to normalize against the maximum
In PySpark, if your dataset is small (can fit into memory of driver), you can do
df.collect()[n]
where df
is the DataFrame object, and n
is the Row of interest. After getting said Row, you can do row.myColumn
or row["myColumn"]
to get the contents, as spelled out in the API docs.

Sometimes you inherit brittle code that is already expecting magic values in a lot of places. Everyone is correct, you should use NULL if possible. However, as a shortcut to make sure every reference to that value is the same, I like to put "constants" (for lack of a better name) in SQL in a scaler function and then call that function when I need the value. That way if I ever want to update them all to be something else, I can do so easily. Or if I want to change the default value moving forward, I only have one place to update it.
The following code creates the function and a table using it for the default DateTime value. Then inserts and select from the table without specifying the value for Modified. Then cleans up after itself. I hope this helps.
-- CREATE FUNCTION
CREATE FUNCTION dbo.DateTime_MinValue ( )
RETURNS DATETIME
AS
BEGIN
DECLARE @dateTime_min DATETIME ;
SET @dateTime_min = '1/1/1753 12:00:00 AM'
RETURN @dateTime_min ;
END ;
GO
-- CREATE TABLE USING FUNCTION FOR DEFAULT
CREATE TABLE TestTable
(
TestTableId INT IDENTITY(1, 1)
PRIMARY KEY CLUSTERED ,
Value VARCHAR(50) ,
Modified DATETIME DEFAULT dbo.DateTime_MinValue()
) ;
-- INSERT VALUE INTO TABLE
INSERT INTO TestTable
( Value )
VALUES ( 'Value' ) ;
-- SELECT FROM TABLE
SELECT TestTableId ,
VALUE ,
Modified
FROM TestTable ;
-- CLEANUP YOUR DB
DROP TABLE TestTable ;
DROP FUNCTION dbo.DateTime_MinValue ;
Now, i'm being told that this will terminate the session (or is it all sessions?) in the 15th minute of use, regardless their activity.
No, that's not true. The session-timeout
configures a per session timeout in case of inactivity.
Are these methods equivalent? Should I favour the web.xml config?
The setting in the web.xml is global, it applies to all sessions of a given context. Programatically, you can change this for a particular session.
If the id
column has no default value, but has NOT NULL
constraint, then you have to provide a value yourself
INSERT INTO dbo.role (id, name, created) VALUES ('something', 'Content Coordinator', GETDATE()), ('Content Viewer', GETDATE())
Check that your labels aren't set to automatically resize. In IB, it's called "Autoshrink" and is right beside the font setting. Programmatically, it's called adjustsFontSizeToFitWidth

Is your MySQL server version 5.5.3 or greater?
The utf8mb4, utf16, and utf32 character sets were added in MySQL 5.5.3.

The Symlink command from the Sublime Text 3 documentation won't work as there is no ~/bin/
directory in Home location on Mac OS X El Capitan or later.
So, we'll need to place the symlink on the /usr/local/bin
as this path would be in our $PATH
variable in most cases.
So, the following command should do the trick:
ln -s "/Applications/Sublime Text.app/Contents/SharedSupport/bin/subl" /usr/local/bin/subl
Once you create the symlink correctly, you would be able to run the Sublime Text 3 like this: subl .
(. means the current directory)
Enabling SQL Server Service Broker requires a database lock. Stop the SQL Server Agent and then execute the following:
USE master ;
GO
ALTER DATABASE [MyDatabase] SET ENABLE_BROKER ;
GO
Change [MyDatabase] with the name of your database in question and then start SQL Server Agent.
If you want to see all the databases that have Service Broker enabled or disabled, then query sys.databases, for instance:
SELECT
name, database_id, is_broker_enabled
FROM sys.databases
If you did all and it didn't work again like mien, do this copy Image.py and ImageTk.py from /usr/lib/python3/dist-packages/PIL on ubuntu and C:/Users/yourComputerName/AppData/Local/Programs/Python/Python36/Lib/PIL on windows to your projects directory and just import them!
It looks like mysql service is either not working or stopped. you can start it by using below command (in Ubuntu):

In other words, you won't see your throughput cut in half, or anything like it, when you add TLS. Answers to the "duplicate" question focus heavily on application performance, and how that compares to SSL overhead. This question specifically excludes application processing, and seeks to compare non-SSL to SSL only. While it makes sense to take a global view of performance when optimizing, that is not what this question is asking.
The main overhead of SSL is the handshake. That's where the expensive asymmetric cryptography happens. After negotiation, relatively efficient symmetric ciphers are used. That's why it can be very helpful to enable SSL sessions for your HTTPS service, where many connections are made. For a long-lived connection, this "end-effect" isn't as significant, and sessions aren't as useful.
Here's an interesting anecdote. When Google switched Gmail to use HTTPS, no additional resources were required; no network hardware, no new hosts. It only increased CPU load by about 1%.
instanceof works for instences of the same class or its subclasses
You can use it to test if an object is an instance of a class, an instance of a subclass, or an instance of a class that implements a particular interface.
ArryaList and RoleList are both instanceof List
While
getClass() == o.getClass() will be true only if both objects ( this and o ) belongs to exactly the same class.
So depending on what you need to compare you could use one or the other.
If your logic is: "One objects is equals to other only if they are both the same class" you should go for the "equals", which I think is most of the cases.
In TortoiseSVN you can configure the proxy server under Settings=> Network
In case anyone was a tired and silly as I was the other night whereupon I came across many threads espousing the different methods to get a javascript redirect, all of which were failing...
You can't use window.location.replace
or document.location.href
or any of your favourite vanilla javascript methods to redirect a page to itself.
So if you're dynamically adding in the redirect path from the back end, or pulling it from a data tag, make sure you do check at some stage for redirects to the current page. It could be as simple as:
if(window.location.href == linkout)
{
location.reload();
}
else
{
window.location.href = linkout;
}
You can use Collections.binarySearch to find the element, then call remove on the returned index.
See the documentation for Collections.binarySearch here: http://docs.oracle.com/javase/1.4.2/docs/api/java/util/Collections.html#binarySearch%28java.util.List,%20java.lang.Object%29
This would require the ArrayTest object to have .equals implemented though. You would also need to call Collections.sort to sort the list. Finally, ArrayTest would have to implement the Comparable interface, so that binarySearch would run correctly.
This is the "proper" way to do it in Java. If you are just looking to solve the problem in a quick and dirty fashion, then you can just iterate over the elements and remove the one with the attribute you are looking for.
In one line, answer is as below;
[ CASE WHEN COLUMN_NAME = 'VALUE' THEN 'SHOW_THIS' ELSE 'SHOW_OTHER' END as ALIAS ]
Yet another way to do this:
(Get-Date).AddDays(-1).Date.AddHours(22)
foreach(range('B','G') as $columnID)
{
$objPHPExcel->getActiveSheet()->getColumnDimension($columnID)->setAutoSize(true);
}
Save this xml and add as a background for the linear layout....
<shape xmlns:android="http://schemas.android.com/apk/res/android">
<stroke android:width="4dp" android:color="#FF00FF00" />
<solid android:color="#ffffff" />
<padding android:left="7dp" android:top="7dp"
android:right="7dp" android:bottom="0dp" />
<corners android:radius="4dp" />
</shape>
Hope this helps! :)
You can use the VisualTreeHelper to find controls. Below is a method that uses the VisualTreeHelper to find a parent control of a specified type. You can use the VisualTreeHelper to find controls in other ways as well.
public static class UIHelper
{
/// <summary>
/// Finds a parent of a given item on the visual tree.
/// </summary>
/// <typeparam name="T">The type of the queried item.</typeparam>
/// <param name="child">A direct or indirect child of the queried item.</param>
/// <returns>The first parent item that matches the submitted type parameter.
/// If not matching item can be found, a null reference is being returned.</returns>
public static T FindVisualParent<T>(DependencyObject child)
where T : DependencyObject
{
// get parent item
DependencyObject parentObject = VisualTreeHelper.GetParent(child);
// we’ve reached the end of the tree
if (parentObject == null) return null;
// check if the parent matches the type we’re looking for
T parent = parentObject as T;
if (parent != null)
{
return parent;
}
else
{
// use recursion to proceed with next level
return FindVisualParent<T>(parentObject);
}
}
}
Call it like this:
Window owner = UIHelper.FindVisualParent<Window>(myControl);
Try using something like this:
<link rel="image_src" href="http://yoursite.com/graphics/yourimage.jpg" /link>`
Seems to work just fine on Firefox as long as you use a full path to your image.
Trouble is it get vertically offset downward for some reason. Image is 200 x 200 as recommended somewhere I read.
In my case, I needed to specify a viahost
and viauser
. Worth trying if you're in a complex system. :)
I solved this (I think as others may have suggested) by creating the binding and endpoint address instances myself - because I did not want to add new settings to the config files (this is a replacement for some existing library code which is used widely, and previously used an older Web Service Reference etc.), and so I wanted to be able to drop this in without having add new config settings everywhere.
var remoteAddress = new System.ServiceModel.EndpointAddress(_webServiceUrl);
using (var productService = new ProductClient(new System.ServiceModel.BasicHttpBinding(), remoteAddress))
{
//set timeout
productService.Endpoint.Binding.SendTimeout = new TimeSpan(0,0,0,_webServiceTimeout);
//call web service method
productResponse = productService.GetProducts();
}
Edit
If you are using https then you need to use BasicHttpsBinding
rather than BasicHttpBinding
.

C does not have its own String data type like Java.
Only we can declare String datatype in C using character array or character pointer For example :
char message[10];
or
char *message;
But you need to declare at least:
char message[14];
to copy "Hello, world!" into message variable.
char largeSrt[] = "123456789-123"; // original string
char * substr;
substr = strchr(largeSrt, '-'); // we save the new string "-123"
int substringLength = strlen(largeSrt) - strlen(substr); // 13-4=9 (bigger string size) - (new string size)
char *newStr = malloc(sizeof(char) * substringLength + 1);// keep memory free to new string
strcpy(newStr, largeSrt, substringLength); // copy only 9 characters
newStr[substringLength] = '\0'; // close the new string with final character
printf("newStr=%s\n", newStr);
free(newStr); // you free the memory

For guys like me, who aren't minimalistic, there is a PECL extension called "intl". I use it for idn conversion since it works way better than the "idn" extension and some other n1 classes like "IntlDateFormatter".
Well, what I want to say is, the "intl" extension has a class called "IntlCalendar" which can handle many international countries (e.g. in Saudi Arabia, sunday is not a weekend day). The IntlCalendar has a method IntlCalendar::isWeekend for that. Maybe you guys give it a shot, I like that "it works for almost every country" fact on these intl-classes.
EDIT: Not quite sure but since PHP 5.5.0, the intl extension is bundled with PHP (--enable-intl).
If you just want to change the legend title, you can do the following:
import seaborn as sns
import matplotlib.pyplot as plt
tips = sns.load_dataset("tips")
g = sns.lmplot(
x="total_bill",
y="tip",
hue="smoker",
data=tips,
legend=True
)
g._legend.set_title("New Title")
Using regex
to parse html is not recommended
regex
is used for regularly occurring patterns.html
is not regular with it's format(except xhtml
).For example html
files are valid even if you don't have a closing tag
!This could break your code.
Use an html parser like htmlagilitypack
You can use this code to retrieve all href's
in anchor tag using HtmlAgilityPack
HtmlDocument doc = new HtmlDocument();
doc.Load(yourStream);
var hrefList = doc.DocumentNode.SelectNodes("//a")
.Select(p => p.GetAttributeValue("href", "not found"))
.ToList();
hrefList
contains all href`s
It is needed whenever you want to send data to the server having characters that cannot be represented in pure ASCII, like 'ñ' or 'ö'.

I found this page because I needed to migrate a site with many many bindings to a new server. I used some of the code here to generate the powershell script below to add the bindings to the new server. Sharing in case it is useful to someone else:
Import-Module WebAdministration
$Websites = Get-ChildItem IIS:\Sites
$site = $Websites | Where-object { $_.Name -eq 'site-name-in-iis-here' }
$Binding = $Site.bindings
[string]$BindingInfo = $Binding.Collection
[string[]]$Bindings = $BindingInfo.Split(" ")
$i = 0
$header = ""
Do{
[string[]]$Bindings2 = $Bindings[($i+1)].Split(":")
Write-Output ("New-WebBinding -Name `"site-name-in-iis-here`" -IPAddress " + $Bindings2[0] + " -Port " + $Bindings2[1] + " -HostHeader `"" + $Bindings2[2] + "`"")
$i=$i+2
} while ($i -lt ($bindings.count))
It generates records that look like this:
New-WebBinding -Name "site-name-in-iis-here" -IPAddress "*" -Port 80 -HostHeader www.aaa.com
I had the same issue. I checked the version of System.Data.SqlServerCe in C:\Windows\assembly. It was 3.5.1.0. So I installed version 4.0.0 from below link (x86) and works fine.
Could you try this one:
create or replace
procedure point_triangle
IS
BEGIN
FOR thisteam in (select P.FIRSTNAME,P.LASTNAME, SUM(P.PTS) S from PLAYERREGULARSEASON P where P.TEAM = 'IND' group by P.FIRSTNAME, P.LASTNAME order by SUM(P.PTS) DESC)
LOOP
dbms_output.put_line(thisteam.FIRSTNAME|| ' ' || thisteam.LASTNAME || ':' || thisteam.S);
END LOOP;
END;
Use this code:
'{:x}'.format(int(line))
it allows you to specify a number of digits too:
'{:06x}'.format(123)
# '00007b'
For Python 2.6 use
'{0:x}'.format(int(line))
or
'{0:06x}'.format(int(line))
I needed to have a button handler that created a form post to another application within the client's browser. I landed on this question but didn't see an answer that suited my scenario. This is what I came up with:
protected void Button1_Click(object sender, EventArgs e)
{
var formPostText = @"<html><body><div>
<form method=""POST"" action=""OtherLogin.aspx"" name=""frm2Post"">
<input type=""hidden"" name=""field1"" value=""" + TextBox1.Text + @""" />
<input type=""hidden"" name=""field2"" value=""" + TextBox2.Text + @""" />
</form></div><script type=""text/javascript"">document.frm2Post.submit();</script></body></html>
";
Response.Write(formPostText);
}
The test Resource files(src/test/resources) are loaded to target/test-classes sub folder. So we can use the below code to load the test resource files.
String resource = "sample.txt";
File file = new File(getClass().getClassLoader().getResource(resource).getFile());
System.out.println(file.getAbsolutePath());
Note : Here the sample.txt file should be placed under src/test/resources folder.

I know this is old but I got a kind of working solution
SELECT Tbla.* FROM Tbla
INNER JOIN Tblb ON
Tblb.col1 Like '%'+Tbla.Col2+'%'
You can expand it further with your where clause etc. I only answered this because this is what I was looking for and I had to figure out a way of doing it.
Add property:
-webkit-box-sizing: border-box; /* Safari/Chrome, other WebKit */
-moz-box-sizing: border-box; /* Firefox, other Gecko */
box-sizing: border-box; /* Opera/IE 8+ */
Note: This won't work in Internet Explorer below version 8.
Using parameters helps prevent SQL Injection attacks when the database is used in conjunction with a program interface such as a desktop program or web site.
In your example, a user can directly run SQL code on your database by crafting statements in txtSalary
.
For example, if they were to write 0 OR 1=1
, the executed SQL would be
SELECT empSalary from employee where salary = 0 or 1=1
whereby all empSalaries would be returned.
Further, a user could perform far worse commands against your database, including deleting it If they wrote 0; Drop Table employee
:
SELECT empSalary from employee where salary = 0; Drop Table employee
The table employee
would then be deleted.
In your case, it looks like you're using .NET. Using parameters is as easy as:
string sql = "SELECT empSalary from employee where salary = @salary";
using (SqlConnection connection = new SqlConnection(/* connection info */))
using (SqlCommand command = new SqlCommand(sql, connection))
{
var salaryParam = new SqlParameter("salary", SqlDbType.Money);
salaryParam.Value = txtMoney.Text;
command.Parameters.Add(salaryParam);
var results = command.ExecuteReader();
}
Dim sql As String = "SELECT empSalary from employee where salary = @salary"
Using connection As New SqlConnection("connectionString")
Using command As New SqlCommand(sql, connection)
Dim salaryParam = New SqlParameter("salary", SqlDbType.Money)
salaryParam.Value = txtMoney.Text
command.Parameters.Add(salaryParam)
Dim results = command.ExecuteReader()
End Using
End Using
Edit 2016-4-25:
As per George Stocker's comment, I changed the sample code to not use AddWithValue
. Also, it is generally recommended that you wrap IDisposable
s in using
statements.
You could try using: ‘
The threading.Timer
object (documentation) can count the ten seconds, then get it to set an Event flag indicating that the loop should exit.
The documentation indicates that the timing might not be exact - you'd have to test whether it's accurate enough for your game.
You can retrieve all the keys of the $_POST array using array_keys(), then construct an email messages with the values of those keys.
var_dump($_POST) will also dump information about all of the information in $_POST for you.
Character.isDigit(string.charAt(0))
Note that this will allow any Unicode digit, not just 0-9. You might prefer:
char c = string.charAt(0);
isDigit = (c >= '0' && c <= '9');
Or the slower regex solutions:
s.substring(0, 1).matches("\\d")
// or the equivalent
s.substring(0, 1).matches("[0-9]")
However, with any of these methods, you must first be sure that the string isn't empty. If it is, charAt(0)
and substring(0, 1)
will throw a StringIndexOutOfBoundsException
. startsWith
does not have this problem.
To make the entire condition one line and avoid length checks, you can alter the regexes to the following:
s.matches("\\d.*")
// or the equivalent
s.matches("[0-9].*")
If the condition does not appear in a tight loop in your program, the small performance hit for using regular expressions is not likely to be noticeable.
You can get some inspiration by reading an entrypoint.sh
script written by the contributors from MySQL that checks whether the specified variables were set.
As the script shows, you can pipe them with -a
, e.g.:
if [ -z "$MYSQL_ROOT_PASSWORD" -a -z "$MYSQL_ALLOW_EMPTY_PASSWORD" -a -z "$MYSQL_RANDOM_ROOT_PASSWORD" ]; then

Do not use the ToList()
method as in the accepted answer !
Running SQL profiler, I verified and found that ToList()
function gets all the records from the database. It is really bad performance !!
I would have run this query by pure sql command as follows:
string query = "Update YourTable Set ... Where ...";
context.Database.ExecuteSqlCommandAsync(query, new SqlParameter("@ColumnY", value1), new SqlParameter("@ColumnZ", value2));
This would operate the update in one-shot without selecting even one row.
In your build.gradle(Module:app), add android-gif-drawable
as a dependency by adding the following code:
allprojects {
repositories {
mavenCentral()
}
}
dependencies {
compile 'pl.droidsonroids.gif:android-gif-drawable:1.2.+'
}
implementation
, so the above line might have to be changed to:
dependencies {
implementation 'pl.droidsonroids.gif:android-gif-drawable:1.2.17'
}
Then sync your project. When synchronization ends, go to your layout file and add the following code:
<pl.droidsonroids.gif.GifImageView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:src="@drawable/gif_file"
/>
And that's it, you can manage it with a simple ImageView.

First convert your string into DateTime variable:
DateTime date = DateTime.Parse(your variable);
Then convert this variable back to string in correct format:
String dateInString = date.ToString("dd-MM-yyyy");
You can do in this way:
Integer i = 1;
new BigInteger("" + i);

To cache static content for 365 days with public cache-control header, IIS can be configured with the following
<staticContent>
<clientCache cacheControlCustom="public" cacheControlMode="UseMaxAge" cacheControlMaxAge="365.00:00:00" />
</staticContent>
This will translate into a header like this:
Cache-Control: public,max-age=31536000
Note that max-age is a delta in seconds, being expressed by a positive 32bit integer as stated in RFC 2616 Sections 14.9.3 and 14.9.4. This represents a maximum value of 2^31 or 2,147,483,648 seconds (over 68 years). However, to better ensure compatibility between clients and servers, we adopt a recommended maximum of 365 days (one year).
As mentioned on other answers, you can use these directives also on the web.config of your site for all static content. As an alternative, you can use it only for contents in a specific location too (on the sample, 30 days public cache for contents in "cdn" folder):
<location path="cdn">
<system.webServer>
<staticContent>
<clientCache cacheControlCustom="public" cacheControlMode="UseMaxAge" cacheControlMaxAge="30.00:00:00"/>
</staticContent>
</system.webServer>
</location>
Using jQuery you can use contents()
. For example:
var inside = $('#one').contents();
Alot of the time the code is correct if you have followed a tutorial but what many beginners do not know is that the scrollView is NOT going to scroll normally through the simulator. It is suppose to scroll only when you press down on the mousepad and simultaneously scroll. Many Experienced XCode/Swift/Obj-C users are so use to doing this and so they do not know how it could possibly be overlooked by beginners. Ciao :-)
@IBOutlet weak var scrollView: UIScrollView!
override func viewDidLoad() {
super.viewDidLoad()
view.addSubview(scrollView)
// Do any additional setup after the view
}
override func viewWillLayoutSubviews(){
super.viewWillLayoutSubviews()
scrollView.contentSize = CGSize(width: 375, height: 800)
}
This code will work perfectly fine as long as you do what I said up above
A Third Answer
Sorry, maybe I have it correct this time...
var savedBox1, savedBox2, state1=0, state2=0;
jQuery(document).ready(function() {
jQuery(".rec1").click(function() {
if (state1==0){
savedBox1 = jQuery('#rec-box').html();
jQuery('#rec-box').html(jQuery(this).next().html());
state1 = 1;
}else{
jQuery('#rec-box').html(savedBox1);
state1 = 0;
}
});
jQuery(".rec2").click(function() {
if (state1==0){
savedBox2 = jQuery('#rec-box2').html();
jQuery('#rec-box2').html(jQuery(this).next().html());
state2 = 1;
}else{
jQuery('#rec-box2').html(savedBox2);
state2 = 0;
}
});
});
Well I'm sure that this is the simplest way to populate JTable from ResultSet, without any external library. I have included comments in this method.
public void resultSetToTableModel(ResultSet rs, JTable table) throws SQLException{
//Create new table model
DefaultTableModel tableModel = new DefaultTableModel();
//Retrieve meta data from ResultSet
ResultSetMetaData metaData = rs.getMetaData();
//Get number of columns from meta data
int columnCount = metaData.getColumnCount();
//Get all column names from meta data and add columns to table model
for (int columnIndex = 1; columnIndex <= columnCount; columnIndex++){
tableModel.addColumn(metaData.getColumnLabel(columnIndex));
}
//Create array of Objects with size of column count from meta data
Object[] row = new Object[columnCount];
//Scroll through result set
while (rs.next()){
//Get object from column with specific index of result set to array of objects
for (int i = 0; i < columnCount; i++){
row[i] = rs.getObject(i+1);
}
//Now add row to table model with that array of objects as an argument
tableModel.addRow(row);
}
//Now add that table model to your table and you are done :D
table.setModel(tableModel);
}
To print all months at once:
import datetime
monthint = list(range(1,13))
for X in monthint:
month = datetime.date(1900, X , 1).strftime('%B')
print(month)
Now it's also possible to reset the database through their web interface.
Go to dashboard.heroku.com select your app and then you'll find the database under the add-ons category, click on it and then you can reset the database.

You can override by enabling Password less authentication. But you should install keys (pub, priv) before going for that.
Execute the following commands at local server.
Local $> ssh-keygen -t rsa
Press ENTER for all options prompted. No values need to be typed.
Local $> cd .ssh
Local $> scp .ssh/id_rsa.pub user@targetmachine:
Prompts for pwd$> ENTERPASSWORD
Connect to remote server using the following command
Local $> ssh user@targetmachine
Prompts for pwd$> ENTERPASSWORD
Execute the following commands at remote server
Remote $> mkdir .ssh
Remote $> chmod 700 .ssh
Remote $> cat id_rsa.pub >> .ssh/authorized_keys
Remote $> chmod 600 .ssh/authorized_keys
Remote $> exit
Execute the following command at local server to test password-less authentication. It should be connected without password.
$> ssh user@targetmachine
In your code you are assigning a native method to a property of custom object.
When you call support.animationFrame(function () {})
, it is executed in the context of current object (ie support). For the native requestAnimationFrame function to work properly, it must be executed in the context of window
.
So the correct usage here is support.animationFrame.call(window, function() {});
.
The same happens with alert too:
var myObj = {
myAlert : alert //copying native alert to an object
};
myObj.myAlert('this is an alert'); //is illegal
myObj.myAlert.call(window, 'this is an alert'); // executing in context of window
Another option is to use Function.prototype.bind() which is part of ES5 standard and available in all modern browsers.
var _raf = window.requestAnimationFrame ||
window.mozRequestAnimationFrame ||
window.webkitRequestAnimationFrame ||
window.msRequestAnimationFrame ||
window.oRequestAnimationFrame;
var support = {
animationFrame: _raf ? _raf.bind(window) : null
};

If using Android Studio, do the following (I've copied and modified @Vinayak Bs answer):
- Select the Project view in the Project sideview (instead of Packages or Android)
- Create a folder called libs in your project's root folder
- Copy your JAR files to the libs folder
- The sideview will be updated and the JAR files will show up in your project
- Now right click on each JAR file you want to import and then select "Add as Library...", which will include it in your project
- After that, all you need to do is reference the new classes in your code, eg.
import javax.mail.*
This worked for me
SELECT schemaname,relname,n_live_tup FROM pg_stat_user_tables ORDER BY n_live_tup DESC;
Make sure you can run powershell scripts (it is disabled by default). Likely you have already done this. http://technet.microsoft.com/en-us/library/ee176949.aspx

Run this python script on your powershell script helloworld.py
:
# -*- coding: iso-8859-1 -*-
import subprocess, sys
p = subprocess.Popen(["powershell.exe",
"C:\\Users\\USER\\Desktop\\helloworld.ps1"],
stdout=sys.stdout)
p.communicate()
This code is based on python3.4 (or any 3.x series interpreter), though it should work on python2.x series as well.

In my case, it was caused by running my django server under http://127.0.0.1:8000/
but sending the ajax call to http://localhost:8000/
. Even though you would expect them to map to the same address, they don't so make sure you're not sending your requests to localhost.
I know this is an older question, but I thought I would also post my solution:
Retrieves the full path of a known folder identified by the folder's
KNOWNFOLDERID
.
And, FOLDERID_CommonStartup
:
Default Path
%ALLUSERSPROFILE%\Microsoft\Windows\Start Menu\Programs\StartUp
There are also managed equivalents, but you haven't told us what you're programming in.
Here is one solution adapted to your example:
interface IenumServiceGetOrderByAttributes {
id: number;
label: string;
key: any
}
interface IenumServiceGetOrderBy extends Array<IenumServiceGetOrderByAttributes> {
}
let result: IenumServiceGetOrderBy;
With this solution you can use all properties and methods of the Array (like:
length, push(), pop(), splice()
...)
The basic advantage of using enum class over normal enums is that you may have same enum variables for 2 different enums and still can resolve them(which has been mentioned as type safe by OP)
For eg:
enum class Color1 { red, green, blue }; //this will compile
enum class Color2 { red, green, blue };
enum Color1 { red, green, blue }; //this will not compile
enum Color2 { red, green, blue };
As for the basic enums, compiler will not be able to distinguish whether red
is refering to the type Color1
or Color2
as in hte below statement.
enum Color1 { red, green, blue };
enum Color2 { red, green, blue };
int x = red; //Compile time error(which red are you refering to??)
break
or goto
while ( true ) {
if ( conditional ) {
break;
}
if ( other conditional ) {
goto EndWhile;
}
}
EndWhile:
DELETE
p1
FROM posts AS p1
CROSS JOIN (
SELECT ID FROM posts GROUP BY id HAVING COUNT(id) > 1
) AS p2
USING (id)
It depends on what type of fading you are looking for.
But with shadow and rounded corners you can get a nice result. Rounded corners because the bigger the shadow, the weirder it will look in the edges unless you balance it out with rounded corners.

To help other bug-hunters. I had this error because the function didn't exist.
I had a spelling error.
Frames have been deprecated because they caused trouble for url navigation and hyperlinking, because the url would just take to you the index page (with the frameset) and there was no way to specify what was in each of the frame windows. Today, webpages are often generated by server-side technologies such as PHP, ASP.NET, Ruby etc. So instead of using frames, pages can simply be generated by merging a template with content like this:
Template File
<html>
<head>
<title>{insert script variable for title}</title>
</head>
<body>
<div class="menu">
{menu items inserted here by server-side scripting}
</div>
<div class="main-content">
{main content inserted here by server-side scripting}
</div>
</body>
</html>
If you don't have full support for a server-side scripting language, you could also use server-side includes (SSI). This will allow you to do the same thing--i.e. generate a single web page from multiple source documents.
But if you really just want to have a section of your webpage be a separate "window" into which you can load other webpages that are not necessarily located on your own server, you will have to use an iframe.
You could emulate your example like this:
Frames Example
<html>
<head>
<title>Frames Test</title>
<style>
.menu {
float:left;
width:20%;
height:80%;
}
.mainContent {
float:left;
width:75%;
height:80%;
}
</style>
</head>
<body>
<iframe class="menu" src="menu.html"></iframe>
<iframe class="mainContent" src="events.html"></iframe>
</body>
</html>
There are probably better ways to achieve the layout. I've used the CSS float attribute, but you could use tables or other methods as well.

Basically I was trying to get my code to have a middle section on a 'row' to auto-adjust to the content on both sides (in my case, a dotted line separator). Like @Michael_B suggested, the key is using display:flex
on the row container and at least making sure your middle container on the row has a flex-grow
value of at least 1 higher than the outer containers (if outer containers don't have any flex-grow
properties applied, middle container only needs 1 for flex-grow
).
Here's a pic of what I was trying to do and sample code for how I solved it.
.row {
background: lightgray;
height: 30px;
width: 100%;
display: flex;
align-items:flex-end;
margin-top:5px;
}
.left {
background:lightblue;
}
.separator{
flex-grow:1;
border-bottom:dotted 2px black;
}
.right {
background:coral;
}

Create your assets directory the same as lib level
like this
projectName
-android
-ios
-lib
-assets
-pubspec.yaml
then your pubspec.yaml like
flutter:
assets:
- assets/images/
now you can use Image.asset("/assets/images/")
To send running process to nohup (http://en.wikipedia.org/wiki/Nohup)
nohup -p pid
, it did not worked for me
Then I tried the following commands and it worked very fine
Run some SOMECOMMAND,
say /usr/bin/python /vol/scripts/python_scripts/retention_all_properties.py 1
.
Ctrl+Z to stop (pause) the program and get back to the shell.
bg
to run it in the background.
disown -h
so that the process isn't killed when the terminal closes.
Type exit
to get out of the shell because now you're good to go as the operation will run in the background in its own process, so it's not tied to a shell.
This process is the equivalent of running nohup SOMECOMMAND
.

I have a cell which is linked to online stock database and updated frequently. I want to trigger a macro whenever the cell value is updated.
I believe this is similar to cell value change by a program or any external data update but above examples somehow do not work for me. I think the problem is because excel internal events are not triggered, but thats my guess.
I did the following,
Private Sub Worksheet_Change(ByVal Target As Range)
If Not Intersect(Target, Target.Worksheets("Symbols").Range("$C$3")) Is Nothing Then
'Run Macro

An illustration of when to prefer the first method to the second one is when you need to avoid overriding a function's previous definitions.
With
if (condition){
function myfunction(){
// Some code
}
}
, this definition of myfunction
will override any previous definition, since it will be done at parse-time.
While
if (condition){
var myfunction = function (){
// Some code
}
}
does the correct job of defining myfunction
only when condition
is met.
To add to Alan Wells's elaborate answer here is a quick fix
you can serve any folder in your computer with Serve
First, navigate using the command line into the folder you'd like to serve.
Then
npx i -g serve
serve
or if you'd like to test Serve without downloading it
npx serve
and that's it! You can view your files at http://localhost:5000

Remove all the texts in android/settings.gradle and paste the below code
rootProject.name = '****Your Project Name****'
apply from: file("../node_modules/@react-native-community/cli-platform-android/native_modules.gradle"); applyNativeModulesSettingsGradle(settings)
include ':app'
This issue will usually happen when you migrate from react-native < 0.60 to react-native >0.60. If you create a new project in react-native >0.60 you will see the same settings as above mentioned
You can use arguments with default values.
def someMethod(def mandatory,def optional=null){}
if argument "optional" not exist, it turns to "null".
You can either return a response as String
as suggested by @vagaasen or you can use ResponseEntity
Object provided by Spring as below. By this way you can also return Http status code
which is more helpful in webservice call.
@RestController
@RequestMapping("/api")
public class MyRestController
{
@GetMapping(path = "/hello", produces=MediaType.APPLICATION_JSON_VALUE)
public ResponseEntity<Object> sayHello()
{
//Get data from service layer into entityList.
List<JSONObject> entities = new ArrayList<JSONObject>();
for (Entity n : entityList) {
JSONObject entity = new JSONObject();
entity.put("aa", "bb");
entities.add(entity);
}
return new ResponseEntity<Object>(entities, HttpStatus.OK);
}
}

The easiest way I have found is to dump the database to a text file, run a sed command to do the replace, and reload the database back into MySQL.
All commands below are bash on Linux.
Dump database to text file
mysqldump -u user -p databasename > ./db.sql
Run sed command to find/replace target string
sed -i 's/oldString/newString/g' ./db.sql
Reload the database into MySQL
mysql -u user -p databasename < ./db.sql
Easy peasy.
After looking through all the different methods posted here, I didn't see anyone utilize TRUE/FALSE
to select and unselect data. So I thought I would share a method utilizing that technique.
n = nrow(dataset)
split = sample(c(TRUE, FALSE), n, replace=TRUE, prob=c(0.75, 0.25))
training = dataset[split, ]
testing = dataset[!split, ]
There are multiple ways of selecting data from R, most commonly people use positive/negative indices to select/unselect respectively. However, the same functionalities can be achieved by using TRUE/FALSE
to select/unselect.
Consider the following example.
# let's explore ways to select every other element
data = c(1, 2, 3, 4, 5)
# using positive indices to select wanted elements
data[c(1, 3, 5)]
[1] 1 3 5
# using negative indices to remove unwanted elements
data[c(-2, -4)]
[1] 1 3 5
# using booleans to select wanted elements
data[c(TRUE, FALSE, TRUE, FALSE, TRUE)]
[1] 1 3 5
# R recycles the TRUE/FALSE vector if it is not the correct dimension
data[c(TRUE, FALSE)]
[1] 1 3 5
Use Python shell to find out the path of Django:
>>> import django
>>> django

Then remove it manually:
sudo rm -rf /usr/local/lib/python2.7/dist-packages/django/
Getting the data after the hashmark in a query string is simple. Here is an example used for when a client accesses a glossary of terms from a book. It takes the name anchor delivered (#tesla), and delivers the client to that term and highlights the term and its description in blue so its easy to see.
A. setup your strings with a div id, so the name anchor goes where its supposed to and the javascript can change the text colors
<div id="tesla">Tesla</div>
<div id="tesla1">An energy company</div>
B. Use Javascript to do the heavy work, on the server side, inserted in your PHP page, or wherever..
<script src="http://code.jquery.com/jquery-1.9.1.min.js"></script>
C. I am launching the java function automatically when the page is loaded.
<script>
$( document ).ready(function() {
D. get the anchor (#tesla) from the url received by the server
var myhash1 = $(location).attr('hash'); //myhash1 == #tesla
E. trim the hash sign off of it
myhash1 = myhash1.substr(1) //myhash1 == tesla
F. I need to highlight the term and the description so i create a new var
var myhash2 = '1';
myhash2 = myhash1.concat(myhash2); //myhash2 == tesla1
G. Now I can manipulate the text color for the term and description
var elem = document.getElementById(myhash1);
elem.style.color = 'blue';
elem = document.getElementById(myhash2);
elem.style.color = 'blue';
});
</script>
H. This works. client clicks link on client side (xyz.com#tesla) and goes right to the term. the term and the description are highlighted in blue by javascript for quick reading .. all other entries left in black..
If you're really bent upon converting Integer to String value, I suggest use String.valueOf(YourIntegerVariable). More details can be found at: http://www.tutorialspoint.com/java/java_string_valueof.htm
First you create the branch locally:
git checkout -b your_branch
And then to create the branch remotely:
git push --set-upstream origin your_branch
Note: This works on the latests versions of git:
$ git --version
git version 2.3.0

Here is a solution using Application
class.
public class AppSingleton extends Application implements Application.ActivityLifecycleCallbacks {
private WeakReference<Context> foregroundActivity;
@Override
public void onActivityResumed(Activity activity) {
foregroundActivity=new WeakReference<Context>(activity);
}
@Override
public void onActivityPaused(Activity activity) {
String class_name_activity=activity.getClass().getCanonicalName();
if (foregroundActivity != null &&
foregroundActivity.get().getClass().getCanonicalName().equals(class_name_activity)) {
foregroundActivity = null;
}
}
//............................
public boolean isOnForeground(@NonNull Context activity_cntxt) {
return isOnForeground(activity_cntxt.getClass().getCanonicalName());
}
public boolean isOnForeground(@NonNull String activity_canonical_name) {
if (foregroundActivity != null && foregroundActivity.get() != null) {
return foregroundActivity.get().getClass().getCanonicalName().equals(activity_canonical_name);
}
return false;
}
}
You can simply use it like follows,
((AppSingleton)context.getApplicationContext()).isOnForeground(context_activity);
If you have a reference to the required Activity or using the canonical name of the Activity, you can find out whether it's in the foreground or not. This solution may not be foolproof. Therefore your comments are really welcome.

I tried searching for documentation on the EM7 OpenSource REST API. No luck so far.
http://blog.sciencelogic.com/sciencelogic-em7-the-next-generation/05/2011
There's a lot of talk about OpenSource REST API, but no link to the actual API or any documentation. Maybe I was impatient.
Here are few things you can try out
$a = Invoke-RestMethod -Uri https://IPADDRESS/resource -Credential $cred -certificate $cert
$a.Results | ConvertFrom-Json
Try this to see if you can filter out the columns that you are getting from the API
$a.Results | ft
or, you can try using this also
$b = Invoke-WebRequest -Uri https://IPADDRESS/resource -Credential $cred -certificate $cert
$b.Content | ConvertFrom-Json
Curl Style Headers
$b.Headers
I tested the IRM / IWR with the twitter JSON api.
$a = Invoke-RestMethod http://search.twitter.com/search.json?q=PowerShell
Hope this helps.
The following example shows commit parents as well:

Yes, return
stops execution and exits the function. return
always** exits its function immediately, with no further execution if it's inside a for loop.
It is easily verified for yourself:
function returnMe() {
for (var i = 0; i < 2; i++) {
if (i === 1) return i;
}
}
console.log(returnMe());
_x000D_
** Notes: See this other answer about the special case of try/catch/finally
and this answer about how forEach loops has its own function scope will not break out of the containing function.
You can use inline styling to limit the height:
<img src="" class="img-responsive" alt="" style="max-height: 400px;">
right click on SQL Server browser and properties, then Connection tab and chose open session with system account and not this account. then apply and chose automatic and finally run the server.
Use Object.keys
:
var foo = {_x000D_
'alpha': 'puffin',_x000D_
'beta': 'beagle'_x000D_
};_x000D_
_x000D_
var keys = Object.keys(foo);_x000D_
console.log(keys) // ['alpha', 'beta'] _x000D_
// (or maybe some other order, keys are unordered).
_x000D_
This is an ES5 feature. This means it works in all modern browsers but will not work in legacy browsers.
The ES5-shim has a implementation of Object.keys

Use the following snippet to add a Switch to your layout via XML:
<Switch
android:id="@+id/on_off_switch"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textOff="OFF"
android:textOn="ON"/>
Then in your Activity's onCreate method, get a reference to your Switch and set its OnCheckedChangeListener:
Switch onOffSwitch = (Switch) findViewById(R.id.on_off_switch);
onOffSwitch.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {
@Override
public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
Log.v("Switch State=", ""+isChecked);
}
});
You could try something like
<form name="message" method="post">
<section>
<div>
<label for="name">Name</label>
<input id="name" type="text" value="" name="name">
</div>
<div>
<label for="email">Email</label>
<input id="email" type="text" value="" name="email">
</div>
</section>
<section>
<div>
<label for="subject">Subject</label>
<input id="subject" type="text" value="" name="subject">
</div>
<div class="full">
<label for="message">Message</label>
<input id="message" type="text" value="" name="message">
</div>
</section>
</form>
and then css it like
form { width: 400px; }
form section div { float: left; }
form section div.full { clear: both; }
form section div label { display: block; }
If you really need this you can achieve your goal with help of separate table for sequencing (if you don't mind) and a trigger.
Tables
CREATE TABLE table1_seq
(
id INT NOT NULL AUTO_INCREMENT PRIMARY KEY
);
CREATE TABLE table1
(
id VARCHAR(7) NOT NULL PRIMARY KEY DEFAULT '0', name VARCHAR(30)
);
Now the trigger
DELIMITER $$
CREATE TRIGGER tg_table1_insert
BEFORE INSERT ON table1
FOR EACH ROW
BEGIN
INSERT INTO table1_seq VALUES (NULL);
SET NEW.id = CONCAT('LHPL', LPAD(LAST_INSERT_ID(), 3, '0'));
END$$
DELIMITER ;
Then you just insert rows to table1
INSERT INTO Table1 (name)
VALUES ('Jhon'), ('Mark');
And you'll have
| ID | NAME | ------------------ | LHPL001 | Jhon | | LHPL002 | Mark |

This works...
from datetime import datetime as dt

r = relativedelta(d1,d2)
if r.years==0:
months = r.months
if r.years>=1:
months = 12*r.years+r.months
return months
#example

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()
This is, in essence, what AJAX is for. Your page loads, and you add an event to an element. When the user causes the event to be triggered, say by clicking something, your Javascript uses the XMLHttpRequest object to send a request to a server.
After the server responds (presumably with output), another Javascript function/event gives you a place to work with that output, including simply sticking it into the page like any other piece of HTML.
You can do it "by hand" with plain Javascript , or you can use jQuery. Depending on the size of your project and particular situation, it may be more simple to just use plain Javascript .
In this very basic example, we send a request to myAjax.php
when the user clicks a link. The server will generate some content, in this case "hello world!". We will put into the HTML element with the id output
.
The javascript
// handles the click event for link 1, sends the query
function getOutput() {
getRequest(
'myAjax.php', // URL for the PHP file
drawOutput, // handle successful request
drawError // handle error
);
return false;
}
// handles drawing an error message
function drawError() {
var container = document.getElementById('output');
container.innerHTML = 'Bummer: there was an error!';
}
// handles the response, adds the html
function drawOutput(responseText) {
var container = document.getElementById('output');
container.innerHTML = responseText;
}
// helper function for cross-browser request object
function getRequest(url, success, error) {
var req = false;
try{
// most browsers
req = new XMLHttpRequest();
} catch (e){
// IE
try{
req = new ActiveXObject("Msxml2.XMLHTTP");
} catch(e) {
// try an older version
try{
req = new ActiveXObject("Microsoft.XMLHTTP");
} catch(e) {
return false;
}
}
}
if (!req) return false;
if (typeof success != 'function') success = function () {};
if (typeof error!= 'function') error = function () {};
req.onreadystatechange = function(){
if(req.readyState == 4) {
return req.status === 200 ?
success(req.responseText) : error(req.status);
}
}
req.open("GET", url, true);
req.send(null);
return req;
}
The HTML
<a href="#" onclick="return getOutput();"> test </a>
<div id="output">waiting for action</div>
The PHP
// file myAjax.php
<?php
echo 'hello world!';
?>

Arguably, that is a lot of Javascript code. You can shorten that up by tightening the blocks or using more terse logic operators, of course, but there's still a lot going on there. If you plan on doing a lot of this type of thing on your project, you might be better off with a javascript library.
Using the same HTML and PHP from above, this is your entire script (with jQuery included on the page). I've tightened up the code a little to be more consistent with jQuery's general style, but you get the idea:
// handles the click event, sends the query
function getOutput() {
$.ajax({
url:'myAjax.php',
complete: function (response) {
$('#output').html(response.responseText);
},
error: function () {
$('#output').html('Bummer: there was an error!');
}
});
return false;
}

Don't rush out for jQuery just yet: adding any library is still adding hundreds or thousands of lines of code to your project just as surely as if you had written them. Inside the jQuery library file, you'll find similar code to that in the first example, plus a whole lot more. That may be a good thing, it may not. Plan, and consider your project's current size and future possibility for expansion and the target environment or platform.
If this is all you need to do, write the plain javascript once and you're done.

As there's already an existing repository, running
git config --bool core.bare true
on the remote repository should suffice
From the core.bare documentation
If true (bare = true), the repository is assumed to be bare with no working directory associated. If this is the case a number of commands that require a working directory will be disabled, such as git-add or git-merge (but you will be able to push to it).
This setting is automatically guessed by git-clone or git-init when the repository is created. By default a repository that ends in "/.git" is assumed to be not bare (bare = false), while all other repositories are assumed to be bare (bare = true).
An one-liner that works with alternative libraries to jQuery:
$('p').filter((i, p) => $(p).text().trim() === "hello").css('font-weight', 'bold');
And this is the equivalent to a jQuery's a:contains("pattern")
selector:
var res = $('a').filter((i, a) => $(a).text().match(/pattern/));
I have experimented many of the backslash escape characters. \n
which is a new line feed can be put anywhere to bring the effect. One important thing to remember while using this character is that the operating system of the machine we are using might affect the output. As an example, I have printed a bunch of escape character and displayed the result as follow to proof that the OS will affect the output.
Code:
#include <stdio.h>
int main(void){
printf("Hello World!");
printf("Goodbye \a");
printf("Hi \b");
printf("Yo\f");
printf("What? \t");
printf("pewpew");
return 0;
}
You can also use svnsync. This only requires read-only access on the source repository
end(preg_split("#(\\\\|\\/)#", Class_Name::class))
Class_Name::class
: return the class with the namespace. So after you only need to create an array, then get the last value of the array.
Coobird's answer is the correct, complete one. However, I combined his hints with those from another site to create code that works in my app (iOS/Objective-C), which I wanted to share with anyone who comes here looking for such a thing. Please, if you like/up-vote this answer, do the same for the originals; all I did was "stand on the shoulders of giants."
As for sort-order, my technique is a modified painter's algorithm: each object has (a) an altitude of the base (I call "level") and (b) an X/Y for the "base" or "foot" of the image (examples: avatar's base is at his feet; tree's base is at it's roots; airplane's base is center-image, etc.) Then I just sort lowest to highest level, then lowest (highest on-screen) to highest base-Y, then lowest (left-most) to highest base-X. This renders the tiles the way one would expect.
Code to convert screen (point) to tile (cell) and back:
typedef struct ASIntCell { // like CGPoint, but with int-s vice float-s
int x;
int y;
} ASIntCell;
// Cell-math helper here:
// http://gamedevelopment.tutsplus.com/tutorials/creating-isometric-worlds-a-primer-for-game-developers--gamedev-6511
// Although we had to rotate the coordinates because...
// X increases NE (not SE)
// Y increases SE (not SW)
+ (ASIntCell) cellForPoint: (CGPoint) point
{
const float halfHeight = rfcRowHeight / 2.;
ASIntCell cell;
cell.x = ((point.x / rfcColWidth) - ((point.y - halfHeight) / rfcRowHeight));
cell.y = ((point.x / rfcColWidth) + ((point.y + halfHeight) / rfcRowHeight));
return cell;
}
// Cell-math helper here:
// http://stackoverflow.com/questions/892811/drawing-isometric-game-worlds/893063
// X increases NE,
// Y increases SE
+ (CGPoint) centerForCell: (ASIntCell) cell
{
CGPoint result;
result.x = (cell.x * rfcColWidth / 2) + (cell.y * rfcColWidth / 2);
result.y = (cell.y * rfcRowHeight / 2) - (cell.x * rfcRowHeight / 2);
return result;
}
In version 12.2 and above, the simplest way to make the query case insensitive is this:

As Kevin points out, URL Schemes are the only way to communicate between apps. So, no, it's not possible to launch arbitrary apps.
But it is possible to launch any app that registers a URL Scheme, whether it's Apple's, yours, or another developer's. The docs are here:
Defining a Custom URL Scheme for Your App
As for launching the phone, looks like your tel:
link needs to have least three digits before the phone will launch. So you can't just drop into the app without dialing a number.
You can even give multiple columns with null values and get multiple quantile values (I use 95 percentile for outlier treatment)
my_df[['field_A','field_B']].dropna().quantile([0.0, .5, .90, .95])
It can also be due to a duplicate entry in any of the tables that are used.
As @cactuaroid mentions in the comments, a value tuple can be used. This saves a few keystrokes and more importantly executes purely on the stack (no Garbage):
(PropA, PropB, PropC, PropD).GetHashCode();
(Note: The original technique using anonymous types seems to create an object on the heap, i.e. garbage, since anonymous types are implemented as classes, though this might be optimized out by the compiler. It would be interesting to benchmark these options, but the tuple option should be superior.)
Microsoft already provides a good generic HashCode generator: Just copy your property/field values to an anonymous type and hash it:
new { PropA, PropB, PropC, PropD }.GetHashCode();
This will work for any number of properties. It does not use boxing. It just uses the algorithm already implemented in the framework for anonymous types.
Just academic version without having clause:
select *
from (
select gid, count(*) as tmpcount from gd group by gid
) as tmp
where tmpcount > 10;
Anything after the "vmargs" is taken to be vm arguments. Just make sure it's before that, which is the last piece in eclipse.ini.
I use that construction whenever I don't want to add complexity to the problem. It's just a list, no need to say what kind of List it is, as it doesn't matter to the problem. I often use Collection for most of my solutions, as, in the end, most of the times, for the rest of the software, what really matters is the content it holds, and I don't want to add new objects to the Collection.
Futhermore, you use that construction when you think that you may want to change the implemenation of list you are using. Let's say you were using the construction with an ArrayList, and your problem wasn't thread safe. Now, you want to make it thread safe, and for part of your solution, you change to use a Vector, for example. As for the other uses of that list won't matter if it's a AraryList or a Vector, just a List, no new modifications will be needed.
Just some other formatting options:
printf("name: %s\targs: %s\tvalue %d\tarraysize %d\n",
a, b, c, d);
printf("name: %s\targs: %s\tvalue %d\tarraysize %d\n",
a, b, c, d);
printf("name: %s\t" "args: %s\t" "value %d\t" "arraysize %d\n",
very_long_name_a, very_long_name_b, very_long_name_c, very_long_name_d);
You can add variations on the theme. The idea is that the printf()
conversion speficiers and the respective variables are all lined up "nicely" (for some values of "nicely").

Using Skip
and Take
is definitely the way to go. If I were implementing this, I would probably write my own extension method to handle paging (to make the code more readable). The implementation can of course use Skip
and Take
:
static class PagingUtils {
public static IEnumerable<T> Page<T>(this IEnumerable<T> en, int pageSize, int page) {
return en.Skip(page * pageSize).Take(pageSize);
}
public static IQueryable<T> Page<T>(this IQueryable<T> en, int pageSize, int page) {
return en.Skip(page * pageSize).Take(pageSize);
}
}
The class defines two extension methods - one for IEnumerable
and one for IQueryable
, which means that you can use it with both LINQ to Objects and LINQ to SQL (when writing database query, the compiler will pick the IQueryable
version).
Depending on your paging requirements, you could also add some additional behavior (for example to handle negative pageSize
or page
value). Here is an example how you would use this extension method in your query:
var q = (from p in products
where p.Show == true
select new { p.Name }).Page(10, pageIndex);
Since MockMvcRequestBuilders#fileUpload
is deprecated, you'll want to use MockMvcRequestBuilders#multipart(String, Object...)
which returns a MockMultipartHttpServletRequestBuilder
. Then chain a bunch of file(MockMultipartFile)
calls.
Here's a working example. Given a @Controller
@Controller
public class NewController {
@RequestMapping(value = "/upload", method = RequestMethod.POST)
@ResponseBody
public String saveAuto(
@RequestPart(value = "json") JsonPojo pojo,
@RequestParam(value = "some-random") String random,
@RequestParam(value = "data", required = false) List<MultipartFile> files) {
System.out.println(random);
System.out.println(pojo.getJson());
for (MultipartFile file : files) {
System.out.println(file.getOriginalFilename());
}
return "success";
}
static class JsonPojo {
private String json;
public String getJson() {
return json;
}
public void setJson(String json) {
this.json = json;
}
}
}
and a unit test
@WebAppConfiguration
@ContextConfiguration(classes = WebConfig.class)
@RunWith(SpringJUnit4ClassRunner.class)
public class Example {
@Autowired
private WebApplicationContext webApplicationContext;
@Test
public void test() throws Exception {
MockMultipartFile firstFile = new MockMultipartFile("data", "filename.txt", "text/plain", "some xml".getBytes());
MockMultipartFile secondFile = new MockMultipartFile("data", "other-file-name.data", "text/plain", "some other type".getBytes());
MockMultipartFile jsonFile = new MockMultipartFile("json", "", "application/json", "{\"json\": \"someValue\"}".getBytes());
MockMvc mockMvc = MockMvcBuilders.webAppContextSetup(webApplicationContext).build();
mockMvc.perform(MockMvcRequestBuilders.multipart("/upload")
.file(firstFile)
.file(secondFile)
.file(jsonFile)
.param("some-random", "4"))
.andExpect(status().is(200))
.andExpect(content().string("success"));
}
}
And the @Configuration
class
@Configuration
@ComponentScan({ "test.controllers" })
@EnableWebMvc
public class WebConfig extends WebMvcConfigurationSupport {
@Bean
public MultipartResolver multipartResolver() {
CommonsMultipartResolver multipartResolver = new CommonsMultipartResolver();
return multipartResolver;
}
}
The test should pass and give you output of
4 // from param
someValue // from json file
filename.txt // from first file
other-file-name.data // from second file
The thing to note is that you are sending the JSON just like any other multipart file, except with a different content type.

The opacity property of the outer DIV cannot be undone by the inner DIV. If you want to achieve transparency, use rgba
or hsla
:
Outer div:
background-color: rgba(255, 255, 255, 0.9); /* Color white with alpha 0.9*/
Inner div:
background-color: #FFF; /* Background white, to override the background propery*/
EDIT
Because you've added filter:alpha(opacity=90)
to your question, I assume that you also want a working solution for (older versions of) IE. This should work (-ms-
prefix for the newest versions of IE):
/*Padded for readability, you can write the following at one line:*/
filter: progid:DXImageTransform.Microsoft.Gradient(
GradientType=1,
startColorStr="#E6FFFFFF",
endColorStr="#E6FFFFFF");
/*Similarly: */
filter: progid:DXImageTransform.Microsoft.Gradient(
GradientType=1,
startColorStr="#E6FFFFFF",
endColorStr="#E6FFFFFF");
I've used the Gradient filter, starting with the same start-
and end-color
, so that the background doesn't show a gradient, but a flat colour. The colour format is in the ARGB hex format. I've written a JavaScript snippet to convert relative opacity values to absolute alpha-hex values:
var opacity = .9;
var A_ofARGB = Math.round(opacity * 255).toString(16);
if(A_ofARGB.length == 1) A_ofARGB = "0"+a_ofARGB;
else if(!A_ofARGB.length) A_ofARGB = "00";
alert(A_ofARGB);
Reading CSV format description makes me feel that using 3rd party library would be less headache than writing it myself:
Wikipedia lists 10 or something known libraries:
I compared libs listed using some kind of check list. OpenCSV turned out a winner to me (YMMV) with the following results:
+ maven
+ maven - release version // had some cryptic issues at _Hudson_ with snapshot references => prefer to be on a safe side
+ code examples
+ open source // as in "can hack myself if needed"
+ understandable javadoc // as opposed to eg javadocs of _genjava gj-csv_
+ compact API // YAGNI (note *flatpack* seems to have much richer API than OpenCSV)
- reference to specification used // I really like it when people can explain what they're doing
- reference to _RFC 4180_ support // would qualify as simplest form of specification to me
- releases changelog // absence is quite a pity, given how simple it'd be to get with maven-changes-plugin // _flatpack_, for comparison, has quite helpful changelog
+ bug tracking
+ active // as in "can submit a bug and expect a fixed release soon"
+ positive feedback // Recommended By 51 users at sourceforge (as of now)
