If you don't want to use "WebClient" or/and need to use the System.Windows.Forms.WebBrowser e.g. because you want simulate a login first, you can use this extended WebBrowser which hooks the "URLDownloadToFile" Method from the Windows URLMON Lib and uses the Context of the WebBrowser

updated() should be what you're looking for:
Called after a data change causes the virtual DOM to be re-rendered and patched.
The component’s DOM will have been updated when this hook is called, so you can perform DOM-dependent operations here.
$timeIn30Minutes = mktime(idate("H"), idate("i") + 30);
or
$timeIn30Minutes = time() + 30*60; // 30 minutes * 60 seconds/minute
The result will be a UNIX timestamp of the current time plus 30 minutes.
In my case I had to compare column E and I.
I used conditional formatting with new rule. Formula was "=IF($E1<>$I1,1,0)" for highlights in orange and "=IF($E1=$I1,1,0)" to highlight in green.
Next problem is how many columns you want to highlight. If you open Conditional Formatting Rules Manager you can edit for each rule domain of applicability: Check "Applies to"
In my case I used "=$E:$E,$I:$I" for both rules so I highlight only two columns for differences - column I and column E.
Almost every logging framework provides a method in which we can pass the throwable object along with a message. Like:
public trace(Marker marker, String msg, Throwable t);
They print the stacktrace of the throwable object.
I found that using the Common Event described above works well and you could have the common event set up like this:
private void checkChanged(object sender, EventArgs e)
{
foreach (RadioButton r in yourPanel.Controls)
{
if (r.Checked)
textBox.Text = r.Text;
}
}
Of course, then you can't have other controls in your panel that you use, but it's useful if you just have a separate panel for all your radio buttons (such as using a sub panel inside a group box or however you prefer to organize your controls)
You may use an iterator over each byte in the output of the subprocess. This allows inline update (lines ending with '\r' overwrite previous output line) from the subprocess:
from subprocess import PIPE, Popen
command = ["my_command", "-my_arg"]
# Open pipe to subprocess
subprocess = Popen(command, stdout=PIPE, stderr=PIPE)
# read each byte of subprocess
while subprocess.poll() is None:
for c in iter(lambda: subprocess.stdout.read(1) if subprocess.poll() is None else {}, b''):
c = c.decode('ascii')
sys.stdout.write(c)
sys.stdout.flush()
if subprocess.returncode != 0:
raise Exception("The subprocess did not terminate correctly.")
(EXCEL 2007 and later)
Either:
Data > Get external data > From Text
Either way, you will be presented with import options, simply select each column containing dates and tell excel to format as "text" not "general".
This is what I've fund out. Maybe it will help to someone:
So here we go:
If You use LINQ with EF looking for some exact elements contained in the list like this:
await context.MyObject1.Include("MyObject2").Where(t => IdList.Contains(t.MyObjectId)).ToListAsync();
everything is going fine until IdList contains more than one Id.
The “timeout” problem comes out if the list contains just one Id. To resolve the issue use if condition to check number of ids in IdList.
Example:
if (IdList.Count == 1)
{
result = await entities. MyObject1.Include("MyObject2").Where(t => IdList.FirstOrDefault()==t. MyObjectId).ToListAsync();
}
else
{
result = await entities. MyObject1.Include("MyObject2").Where(t => IdList.Contains(t. MyObjectId)).ToListAsync();
}
Explanation:
Simply try to use Sql Profiler and check the Select statement generated by Entity frameeork. …
Express.js created by TJ Holowaychuk and now managed by the community. It is one of the most popular frameworks in the node.js. Express can also be used to develop various products such as web applications or RESTful API.For more information please read on the expressjs.com official site.
With HTML5 you can do
<input type="number">
You can also use a regex pattern to limit the input text.
<input type="text" pattern="^[0-9]*$" />
Possibly unrelated, but if you want to start a new line after the current line, you can use o anywhere in the line.
Here is the best way to find out Foreign Key Relationship in all Database.
exec sp_helpconstraint 'Table Name'
and one more way
select * from INFORMATION_SCHEMA.KEY_COLUMN_USAGE where TABLE_NAME='Table Name'
--and left(CONSTRAINT_NAME,2)='FK'(If you want single key)
This can easily warp a normal human brain, so I've found a visual approach to be easier to understand:
If two ranges are "too fat" to fit in a slot that is exactly the sum of the width of both, then they overlap.
For ranges [a1, a2]
and [b1, b2]
this would be:
/**
* we are testing for:
* max point - min point < w1 + w2
**/
if max(a2, b2) - min(a1, b1) < (a2 - a1) + (b2 - b1) {
// too fat -- they overlap!
}
You could create your own class of type Quiz and then deserialize with strong type:
Example:
quizresult = JsonConvert.DeserializeObject<Quiz>(args.Message,
new JsonSerializerSettings
{
Error = delegate(object sender1, ErrorEventArgs args1)
{
errors.Add(args1.ErrorContext.Error.Message);
args1.ErrorContext.Handled = true;
}
});
And you could also apply a schema validation.
Yes. Class can have private constructor. Even abstract class can have private constructor.
By making constructor private, we prevent the class from being instantiated as well as subclassing of that class.
Here are some of the uses of private constructor :
Yes, you can group by multiple columns. For example,
SELECT * FROM table
GROUP BY col1, col2
The results will first be grouped by col1, then by col2. In MySQL, column preference goes from left to right.
Look at this tutorial or this one, they are both pretty simple. If you are interested in an alternative this is how you do file I/O in C.
Some things to keep in mind, use single quotes '
when dealing with single characters, and double "
for strings. Also it is a bad habit to use global variables when not necessary.
Have fun!
Per Microsoft's KB, try allowing programmatic access to the Visual Basic project:
- Click the Microsoft Office Button, and then click Excel Options.
- Click Trust Center.
- Click Trust Center Settings.
- Click Macro Settings.
- Click to select the Trust access to the VBA project object model check box.
- Click OK to close the Excel Options dialog box.
- You may need to close and re-open excel.
In addition to @delmadord's answer and your comments:
Currently there is no method to create subquery in FROM
clause, so you need to manually use raw statement, then, if necessary, you will merge all the bindings:
$sub = Abc::where(..)->groupBy(..); // Eloquent Builder instance
$count = DB::table( DB::raw("({$sub->toSql()}) as sub") )
->mergeBindings($sub->getQuery()) // you need to get underlying Query Builder
->count();
Mind that you need to merge bindings in correct order. If you have other bound clauses, you must put them after mergeBindings
:
$count = DB::table( DB::raw("({$sub->toSql()}) as sub") )
// ->where(..) wrong
->mergeBindings($sub->getQuery()) // you need to get underlying Query Builder
// ->where(..) correct
->count();
Every webkit based browser should support the properties -webkit-margin-collapse
. There are also subproperties to only set it for the top or bottom margin. You can give it the values collapse (default), discard (sets margin to 0 if there is a neighboring margin), and separate (prevents margin collapse).
I've tested that this works on 2014 versions of Chrome and Safari. Unfortunately, I don't think this would be supported in IE because it's not based on webkit.
Read Apple's Safari CSS Reference for a full explanation.
If you check Mozilla's CSS webkit extensions page, they list these properties as proprietary and recommend not to use them. This is because they're likely not going to go into standard CSS anytime soon and only webkit based browsers will support them.
I used a hidden checkbox to persistent view of some message. The checkbox could be hidden (display:none) or not. This is a tiny code that I could write.
You can see and test the demo on JSFiddle
HTML:
<input type=checkbox id="show">
<label for="show">Help?</label>
<span id="content">Do you need some help?</span>
CSS:
#show,#content{display:none;}
#show:checked~#content{display:block;}
Run code snippet:
#show,#content{display:none;}_x000D_
#show:checked~#content{display:block;}
_x000D_
<input id="show" type=checkbox>_x000D_
<label for="show">Click for Help</label>_x000D_
<span id="content">Do you need some help?</span>
_x000D_
However, I might not be taking the best approach, but this is how I have created some Switch

I only use MicrosoftAdvertising.Mobile and Microsoft.Advertising.Mobile.UI and I am served ads. The SDK should only add the DLLs not reference itself.
Note: You need to explicitly set width and height Make sure the phone dialer, and web browser capabilities are enabled
Followup note: Make sure that after you've removed the SDK DLL, that the xmlns references are not still pointing to it. The best route to take here is
Here is the xmlns reference:
xmlns:AdNamepace="clr-namespace:Microsoft.Advertising.Mobile.UI;assembly=Microsoft.Advertising.Mobile.UI"
Then the ad itself:
<AdNamespace:AdControl x:Name="myAd" Height="80" Width="480" AdUnitId="yourAdUnitIdHere" ApplicationId="yourIdHere"/>
Why not go even simpler with either one of these options:
$("#box").html('<div id="myid" style="display:block; float:left;width:'+width+'px; height:'+height+'px; margin-top:'+positionY+'px;margin-left:'+positionX+'px;border:1px dashed #CCCCCC;"></div>');
Or, if you want to append it to existing content:
$("#box").append('<div id="myid" style="display:block; float:left;width:'+width+'px; height:'+height+'px; margin-top:'+positionY+'px;margin-left:'+positionX+'px;border:1px dashed #CCCCCC;"></div>');
Note: I put the id="myid"
right into the HTML string rather than using separate code to set it.
Both the .html()
and .append()
jQuery methods can take a string of HTML so there's no need to use a separate step for creating the objects.
I'm not sure if my answer is direct answer to original question, but as I suppose a lot of people come here to just find a way to tell their IDEs to understand types, I'll share what I found.
If you want to tell VSCode to understand your types, do as follows. Please pay attention that js
runtime and NodeJS
does not care about these types at all.
1- Create a file with .d.ts
ending: e.g: index.d.ts
. You can create this file in another folder. for example: types/index.d.ts
2- Suppose we want to have a function called view
. Add these lines to index.d.ts
:
/**
* Use express res.render function to render view file inside layout file.
*
* @param {string} view The path of the view file, relative to view root dir.
* @param {object} options The options to send to view file for ejs to use when rendering.
* @returns {Express.Response.render} .
*/
view(view: string, options?: object): Express.Response.render;
3- Create a jsconfig.json
file in you project's root. (It seems that just creating this file is enough for VSCode to search for your types).
Now suppose we want to add this type to another library types. (As my own situation). We can use some ts
keywords. And as long as VSCode understands ts
we have no problem with it.
For example if you want to add this view
function to response from expressjs, change index.d.ts
file as follows:
export declare global {
namespace Express {
interface Response {
/**
* Use express res.render function to render view file inside layout file.
*
* @param {string} view The path of the view file, relative to view root dir.
* @param {object} options The options to send to view file for ejs to use when rendering.
* @returns {Express.Response.render} .
*/
view(view: string, options?: object): Express.Response.render;
}
}
}
In case that you're interested in specific lines, use a result-array:
declare RESULT=($(./myscript)) # (..) = array
echo "First line: ${RESULT[0]}"
echo "Second line: ${RESULT[1]}"
echo "N-th line: ${RESULT[N]}"
The simplest way to initialize an array
Create array
$array = @()
Create your header
$line = "" | select name,age,phone
Fill the line
$line.name = "Leandro"
$line.age = "39"
$line.phone = "555-555555"
Add line to $array
$array += $line
Result
$array
name age phone

The standard best practice for REST APIs is to have a hyphen, not camelcase or underscores.
This comes from Mark Masse's "REST API Design Rulebook" from Oreilly.
In addition, note that Stack Overflow itself uses hyphens in the URL: .../hyphen-underscore-or-camelcase-as-word-delimiter-in-uris
As does WordPress: http://inventwithpython.com/blog/2012/03/18/how-much-math-do-i-need-to-know-to-program-not-that-much-actually
Sorry, don't have enough rep, or would have commented on CraigTP's answer.
I found the solution from the 1st link - C# Editable ListView, quite easy to use. The general idea is to:
SubItem
that was selected and overlay a TextBox
with the SubItem
's text over the SubItem
TextBox
focusSubItem
's text to that of TextBox
's when TextBox
loses focusWhat a workaround for a seemingly simple operation :-|

Identifiers (including column names) that are not double-quoted are folded to lower case in PostgreSQL. Column names that were created with double-quotes and thereby retained upper-case letters (and/or other syntax violations) have to be double-quoted for the rest of their life:
"first_Name"
Values (string literals / constants) are enclosed in single quotes:
'xyz'
So, yes, PostgreSQL column names are case-sensitive (when double-quoted):
SELECT * FROM persons WHERE "first_Name" = 'xyz';
Read the manual on identifiers here.
My standing advice is to use legal, lower-case names exclusively so double-quoting is not needed.
For a div-Element you could just set the opacity via a class to enable or disable the effect.
.mute-all {
opacity: 0.4;
}
By default, CORS does not include cookies on cross-origin requests. This is different from other cross-origin techniques such as JSON-P. JSON-P always includes cookies with the request, and this behavior can lead to a class of vulnerabilities called cross-site request forgery, or CSRF.
In order to reduce the chance of CSRF vulnerabilities in CORS, CORS requires both the server and the client to acknowledge that it is ok to include cookies on requests. Doing this makes cookies an active decision, rather than something that happens passively without any control.
The client code must set the withCredentials
property on the XMLHttpRequest
to true
in order to give permission.
However, this header alone is not enough. The server must respond with the Access-Control-Allow-Credentials
header. Responding with this header to true
means that the server allows cookies (or other user credentials) to be included on cross-origin requests.
You also need to make sure your browser isn't blocking third-party cookies if you want cross-origin credentialed requests to work.
Note that regardless of whether you are making same-origin or cross-origin requests, you need to protect your site from CSRF (especially if your request includes cookies).
The short answer: there is no difference.
The long answer: CHARACTER VARYING
is the official type name from the ANSI SQL standard, which all compliant databases are required to support. VARCHAR
is a shorter alias which all modern databases also support. I prefer VARCHAR
because it's shorter and because the longer name feels pedantic. However, postgres tools like pg_dump
and \d
will output character varying
.
Realised that I was using OpenJDK when I saw this error. Fixed it once I installed the Oracle JDK instead.
You should be able to simply let PIL get the filetype from extension, i.e. use:
j.save("C:/Users/User/Desktop/mesh_trans.bmp")
The SQL WITH clause was introduced by Oracle in the Oracle 9i release 2 database. The SQL WITH clause allows you to give a sub-query block a name (a process also called sub-query refactoring), which can be referenced in several places within the main SQL query. The name assigned to the sub-query is treated as though it was an inline view or table. The SQL WITH clause is basically a drop-in replacement to the normal sub-query.
Syntax For The SQL WITH Clause
The following is the syntax of the SQL WITH clause when using a single sub-query alias.
WITH <alias_name> AS (sql_subquery_statement)
SELECT column_list FROM <alias_name>[,table_name]
[WHERE <join_condition>]
When using multiple sub-query aliases, the syntax is as follows.
WITH <alias_name_A> AS (sql_subquery_statement),
<alias_name_B> AS(sql_subquery_statement_from_alias_name_A
or sql_subquery_statement )
SELECT <column_list>
FROM <alias_name_A>, <alias_name_B> [,table_names]
[WHERE <join_condition>]
In the syntax documentation above, the occurrences of alias_name
is a meaningful name you would give to the sub-query after the AS clause. Each sub-query should be separated with a comma Example for WITH statement. The rest of the queries follow the standard formats for simple and complex SQL SELECT queries.

I guess you're searching for this custom function. It takes a data-toggle attribute and creates dynamically the necessary div to place the remote content. Just place the data-toggle="ajaxModal" on any link you want to load via AJAX.
The JS part:
$('[data-toggle="ajaxModal"]').on('click',
function(e) {
$('#ajaxModal').remove();

var $this = $(this)

$('body').append($modal);

Finally, in the remote content, you need to put the entire structure to work.

<a href="#" class="btn btn-primary">Button</a>
<a href="#" class="btn btn-primary">Another button...</a>
</div>
</div><!-- /.modal-content -->
</div><!-- /.modal-dialog -->
If this android:divider="@null"
doesn't work, maybe changing your ListViews for Recycler Views?
Play cross browser compatible notifications
As adviced by @Tim Tisdall from this post , Check Howler.js Plugin.
Browsers like chrome disables javascript
execution when minimized or inactive for performance improvements. But This plays notification sounds even if browser is inactive or minimized by the user.
var sound =new Howl({
src: ['../sounds/rings.mp3','../sounds/rings.wav','../sounds/rings.ogg',
'../sounds/rings.aiff'],
autoplay: true,
loop: true
});
sound.play();
Hope helps someone.
Inside in yours classses on which is complain maven is some dependecy which belongs to some jar's try right these jars re-build with maven command, i use this command mvn clean install -DskipTests=true
should be work in this case when some symbols from classes is missing
function checkArrowKeys(e){
var arrs= ['left', 'up', 'right', 'down'],
key= window.event? event.keyCode: e.keyCode;
if(key && key>36 && key<41) alert(arrs[key-37]);
}

I found this by adapting some tutos. Thanks to google, and to all of you ;)
def findall(L, test):
i=0
indices = []
while(True):
try:
# next value in list passing the test
nextvalue = filter(test, L[i:])[0]
# add index of this value in the index list,
# by searching the value in L[i:]
indices.append(L.index(nextvalue, i))
# iterate i, that is the next index from where to search
i=indices[-1]+1
#when there is no further "good value", filter returns [],
# hence there is an out of range exeption
except IndexError:
return indices
A very simple use:
a = [0,0,2,1]
ind = findall(a, lambda x:x>0))
[2, 3]
P.S. scuse my english
Yes I think this would be quicker.

FYI - I had this issue as well and it turned out that my html listed the .jpg file with a .JPG in caps, but the file itself was lowercase .jpg. That rendered fine locally and using Codekit, but when it was pushed to the web it wouldn't load. Simply changing the file names to have a lowercase .jpg extension to match the html did the trick.
For people already using lodash
Most of these example are really good and cover a lot of cases. But if you 'know' that you only have English text, here's my version that's super easy to read :)

Using alternative dplyr package:

df <- df %>% mutate(id = row_number())
Your best bet is to have both repos on your local machine and use the linux diff command with the two directories as parameters:
diff -r repo-A repo-B
NULL
is not a keyword. It's an identifier defined in some standard headers. You can include
#include <cstddef>
To have it in scope, including some other basics, like std::size_t
.
If someone else needs a generic utility type to do this, I came up with the following solution:
/**
* Returns object T, but with T[K] overridden to type U.
* @example
* type MyObject = { a: number, b: string }
* OverrideProperty<MyObject, "a", string> // returns { a: string, b: string }
*/
export type OverrideProperty<T, K extends keyof T, U> = Omit<T, K> & { [P in keyof Pick<T, K>]: U };
I needed this because in my case, the key to override was a generic itself.
If you don't have Omit
ready, see Exclude property from type.
You can solve the negative bearing problem by adding 360°. Unfortunately, this might result in bearings larger than 360° for positive bearings. This is a good candidate for the modulo operator, so all in all you should add the line
Bearing = (Bearing + 360) % 360
at the end of your method.
Use the string concatenation operator:
Dim str As String = New String("") & "some other string"
Strings in .NET are immutable and thus there exist no concept of appending strings. All string modifications causes a new string to be created and returned.
This obviously cause a terrible performance. In common everyday code this isn't an issue, but if you're doing intensive string operations in which time is of the essence then you will benefit from looking into the StringBuilder class. It allow you to queue appends. Once you're done appending you can ask it to actually perform all the queued operations.
See "How to: Concatenate Multiple Strings" for more information on both methods.
I have tested a full layout using flexbox it contains header, footer, main body with left, center and right panels and the panels can contain menu items or footer and headers that should scroll. Pretty complex
IE11 and even IE EDGE have some problems displaying the flex content but it can be overcome. I have tested it in most browsers and it seems to work.
Some fixed i have applies are IE11 height bug, Adding height:100vh and min-height:100% to the html/body. this also helps to not have to set height on container in the dom. Also make the body/html a flex container. Otherwise IE11 will compress the view.
html,body {
display: flex;
flex-flow:column nowrap;
height:100vh; /* fix IE11 */
min-height:100%; /* fix IE11 */
}
A fix for IE EDGE that overflows the flex container: overflow:hidden on main flex container. if you remove the overflow, IE EDGE wil push the content out of the viewport instead of containing it inside the flex main container.
main{
flex:1 1 auto;
overflow:hidden; /* IE EDGE overflow fix */
}
You can see my testing and example on my codepen page. I remarked the important css parts with the fixes i have applied and hope someone finds it useful.
You can use this javascript code to redirect after a specific time. Hope it will work.

While technically correct, the other answers would benefit from an explanation of Angular's URL-to-route matching. I don't think you can fully (pardon the pun) understand what pathMatch: full
does if you don't know how the router works in the first place.
Let's first define a few basic things. We'll use this URL as an example: /users/james/articles?from=134#section
.
It may be obvious but let's first point out that query parameters (?from=134
) and fragments (#section
) do not play any role in path matching. Only the base url (/users/james/articles
) matters.
Angular splits URLs into segments. The segments of /users/james/articles
are, of course, users
, james
and articles
.
The router configuration is a tree structure with a single root node. Each Route
object is a node, which may have children
nodes, which may in turn have other children
or be leaf nodes.
The goal of the router is to find a router configuration branch, starting at the root node, which would match exactly all (!!!) segments of the URL. This is crucial! If Angular does not find a route configuration branch which could match the whole URL - no more and no less - it will not render anything.
E.g. if your target URL is /a/b/c
but the router is only able to match either /a/b
or /a/b/c/d
, then there is no match and the application will not render anything.
Finally, routes with redirectTo
behave slightly differently than regular routes, and it seems to me that they would be the only place where anyone would really ever want to use pathMatch: full
. But we will get to this later.
prefix
) path matchingThe reasoning behind the name prefix
is that such a route configuration will check if the configured path
is a prefix of the remaining URL segments. However, the router is only able to match full segments, which makes this naming slightly confusing.
Anyway, let's say this is our root-level router configuration:
const routes: Routes = [
{
path: 'products',
children: [
{
path: ':productID',
component: ProductComponent,
},
],
},
{
path: ':other',
children: [
{
path: 'tricks',
component: TricksComponent,
},
],
},
{
path: 'user',
component: UsersonComponent,
},
{
path: 'users',
children: [
{
path: 'permissions',
component: UsersPermissionsComponent,
},
{
path: ':userID',
children: [
{
path: 'comments',
component: UserCommentsComponent,
},
{
path: 'articles',
component: UserArticlesComponent,
},
],
},
],
},
];
Note that every single Route
object here uses the default matching strategy, which is prefix
. This strategy means that the router iterates over the whole configuration tree and tries to match it against the target URL segment by segment until the URL is fully matched. Here's how it would be done for this example:
users
.'products' !== 'users'
, so skip that branch. Note that we are using an equality check rather than a .startsWith()
or .includes()
- only full segment matches count!:other
matches any value, so it's a match. However, the target URL is not yet fully matched (we still need to match james
and articles
), thus the router looks for children.:other
is tricks
, which is !== 'james'
, hence not a match.'user' !== 'users
, skip branch.'users' === 'users
- the segment matches. However, this is not a full match yet, thus we need to look for children (same as in step 3).'permissions' !== 'james'
, skip it.:userID
matches anything, thus we have a match for the james
segment. However this is still not a full match, thus we need to look for a child which would match articles
.
:userID
has a child route articles
, which gives us a full match! Thus the application renders UserArticlesComponent
.full
) matchingImagine now that the users
route configuration object looked like this:
{
path: 'users',
component: UsersComponent,
pathMatch: 'full',
children: [
{
path: 'permissions',
component: UsersPermissionsComponent,
},
{
path: ':userID',
component: UserComponent,
children: [
{
path: 'comments',
component: UserCommentsComponent,
},
{
path: 'articles',
component: UserArticlesComponent,
},
],
},
],
}
Note the usage of pathMatch: full
. If this were the case, steps 1-5 would be the same, however step 6 would be different:
'users' !== 'users/james/articles
- the segment does not match because the path configuration users
with pathMatch: full
does not match the full URL, which is users/james/articles
.What if we had this instead:
{
path: 'users/:userID',
component: UsersComponent,
pathMatch: 'full',
children: [
{
path: 'comments',
component: UserCommentsComponent,
},
{
path: 'articles',
component: UserArticlesComponent,
},
],
}
users/:userID
with pathMatch: full
matches only users/james
thus it's a no-match once again, and the application renders nothing.
Let's consider this:
{
path: 'users',
children: [
{
path: 'permissions',
component: UsersPermissionsComponent,
},
{
path: ':userID',
component: UserComponent,
pathMatch: 'full',
children: [
{
path: 'comments',
component: UserCommentsComponent,
},
{
path: 'articles',
component: UserArticlesComponent,
},
],
},
],
}
In this case:
'users' === 'users
- the segment matches, but james/articles
still remains unmatched. Let's look for children.'permissions' !== 'james'
- skip.:userID'
can only match a single segment, which would be james
. However, it's a pathMatch: full
route, and it must match james/articles
(the whole remaining URL). It's not able to do that and thus it's not a match (so we skip this branch)!As you may have noticed, a pathMatch: full
configuration is basically saying this:
Ignore my children and only match me. If I am not able to match all of the remaining URL segments myself, then move on.
Any Route
which has defined a redirectTo
will be matched against the target URL according to the same principles. The only difference here is that the redirect is applied as soon as a segment matches. This means that if a redirecting route is using the default prefix
strategy, a partial match is enough to cause a redirect. Here's a good example:
const routes: Routes = [
{
path: 'not-found',
component: NotFoundComponent,
},
{
path: 'users',
redirectTo: 'not-found',
},
{
path: 'users/:userID',
children: [
{
path: 'comments',
component: UserCommentsComponent,
},
{
path: 'articles',
component: UserArticlesComponent,
},
],
},
];
For our initial URL (/users/james/articles
), here's what would happen:
'not-found' !== 'users'
- skip it.'users' === 'users'
- we have a match.redirectTo: 'not-found'
, which is applied immediately.not-found
.not-found
right away. The application renders NotFoundComponent
.Now consider what would happen if the users
route also had pathMatch: full
:
const routes: Routes = [
{
path: 'not-found',
component: NotFoundComponent,
},
{
path: 'users',
pathMatch: 'full',
redirectTo: 'not-found',
},
{
path: 'users/:userID',
children: [
{
path: 'comments',
component: UserCommentsComponent,
},
{
path: 'articles',
component: UserArticlesComponent,
},
],
},
];
'not-found' !== 'users'
- skip it.users
would match the first segment of the URL, but the route configuration requires a full
match, thus skip it.'users/:userID'
matches users/james
. articles
is still not matched but this route has children.articles
in the children. The whole URL is now matched and the application renders UserArticlesComponent
.path: ''
)The empty path is a bit of a special case because it can match any segment without "consuming" it (so it's children would have to match that segment again). Consider this example:
const routes: Routes = [
{
path: '',
children: [
{
path: 'users',
component: BadUsersComponent,
}
]
},
{
path: 'users',
component: GoodUsersComponent,
},
];
Let's say we are trying to access /users
:
path: ''
will always match, thus the route matches. However, the whole URL has not been matched - we still need to match users
!users
, which matches the remaining (and only!) segment and we have a full match. The application renders BadUsersComponent
.The OP used this router configuration:
const routes: Routes = [
{
path: 'welcome',
component: WelcomeComponent,
},
{
path: '',
redirectTo: 'welcome',
pathMatch: 'full',
},
{
path: '**',
redirectTo: 'welcome',
pathMatch: 'full',
},
];
If we are navigating to the root URL (/
), here's how the router would resolve that:
welcome
does not match an empty segment, so skip it.path: ''
matches the empty segment. It has a pathMatch: 'full'
, which is also satisfied as we have matched the whole URL (it had a single empty segment).welcome
happens and the application renders WelcomeComponent
.pathMatch: 'full'
?Actually, one would expect the whole thing to behave exactly the same. However, Angular explicitly prevents such a configuration ({ path: '', redirectTo: 'welcome' }
) because if you put this Route
above welcome
, it would theoretically create an endless loop of redirects. So Angular just throws an error, which is why the application would not work at all! (https://angular.io/api/router/Route#pathMatch)
Actually, this does not make too much sense to me because Angular also has implemented a protection against such endless redirects - it only runs a single redirect per routing level! This would stop all further redirects (as you'll see in the example below).
path: '**'
?path: '**'
will match absolutely anything (af/frewf/321532152/fsa
is a match) with or without a pathMatch: 'full'
.
Also, since it matches everything, the root path is also included, which makes { path: '', redirectTo: 'welcome' }
completely redundant in this setup.
Funnily enough, it is perfectly fine to have this configuration:
const routes: Routes = [
{
path: '**',
redirectTo: 'welcome'
},
{
path: 'welcome',
component: WelcomeComponent,
},
];
If we navigate to /welcome
, path: '**'
will be a match and a redirect to welcome will happen. Theoretically this should kick off an endless loop of redirects but Angular stops that immediately (because of the protection I mentioned earlier) and the whole thing works just fine.
This should do it, let me know if you have trouble with it:
Sub foo()
Dim x As Workbook
Dim y As Workbook
'## Open both workbooks first:
Set x = Workbooks.Open(" path to copying book ")
Set y = Workbooks.Open(" path to destination book ")
'Now, copy what you want from x:
x.Sheets("name of copying sheet").Range("A1").Copy
'Now, paste to y worksheet:
y.Sheets("sheetname").Range("A1").PasteSpecial
'Close x:
x.Close
End Sub
Alternatively, you could just:
Sub foo2()
Dim x As Workbook
Dim y As Workbook
'## Open both workbooks first:
Set x = Workbooks.Open(" path to copying book ")
Set y = Workbooks.Open(" path to destination book ")
'Now, transfer values from x to y:
y.Sheets("sheetname").Range("A1").Value = x.Sheets("name of copying sheet").Range("A1")
'Close x:
x.Close
End Sub
To extend this to the entire sheet:
With x.Sheets("name of copying sheet").UsedRange
'Now, paste to y worksheet:
y.Sheets("sheet name").Range("A1").Resize( _
.Rows.Count, .Columns.Count) = .Value
End With
And yet another way, store the value as a variable and write the variable to the destination:
Sub foo3()
Dim x As Workbook
Dim y As Workbook
Dim vals as Variant
'## Open both workbooks first:
Set x = Workbooks.Open(" path to copying book ")
Set y = Workbooks.Open(" path to destination book ")
'Store the value in a variable:
vals = x.Sheets("name of sheet").Range("A1").Value
'Use the variable to assign a value to the other file/sheet:
y.Sheets("sheetname").Range("A1").Value = vals
'Close x:
x.Close
End Sub
The last method above is usually the fastest for most applications, but do note that for very large datasets (100k rows) it's observed that the Clipboard actually outperforms the array dump:
Copy/PasteSpecial vs Range.Value = Range.Value
That said, there are other considerations than just speed, and it may be the case that the performance hit on a large dataset is worth the tradeoff, to avoid interacting with the Clipboard.

Dataframes have a sort_index
method which returns a copy by default. Pass inplace=True
to operate in place.
import pandas as pd
df = pd.DataFrame([1, 2, 3, 4, 5], index=[100, 29, 234, 1, 150], columns=['A'])
df.sort_index(inplace=True)
print(df.to_string())
Gives me:

It is very important to understand both sessionStorage
and localStorage
as they both have different uses:
From MDN:
All of your web storage data is contained within two object-like structures inside the browser: sessionStorage and localStorage. The first one persists data for as long as the browser is open (the data is lost when the browser is closed) and the second one persists data even after the browser is closed and then opened again.
sessionStorage
- Saves data until the browser is closed, the data is deleted when the tab/browser is closed.
localStorage
- Saves data "forever" even after the browser is closed BUT you shouldn't count on the data you store to be there later, the data might get deleted by the browser at any time because of pretty much anything, or deleted by the user, best practice would be to validate that the data is there first, and continue the rest if it is there. (or set it up again if its not there)
To understand more, read here: localStorage | sessionStorage
Assuming the .resx file was added using Visual Studio under the project properties, there is an easier and less error prone way to access the string.
Accessing the string is then as easy as:
var resourceManager = JoshCodes.Core.Testing.Unit.Properties.Resources.ResourceManager;
var exampleXmlString = resourceManager.GetString("exampleXml");
Replace JoshCodes.Core.Testing.Unit
with the project's default namespace.

git stash-staged
After creating an alias:
git config --global alias.stash-staged '!bash -c "git stash -- \$(git diff --staged --name-only)"'
Here git diff
returns list of --staged
files --name-only
And then we pass this list as pathspec
to git stash
commad.
From man git stash
:
git stash [--] [<pathspec>...]
<pathspec>...
The new stash entry records the modified states only for the files
that match the pathspec. The index entries and working tree
files are then rolled back to the state in HEAD only for these
files, too, leaving files that do not match the pathspec intact.
Thanks for the answer of https://stackoverflow.com/a/65513726/889126, it gave me an idea to make a complete bash script as it is
export api_image_id=$(docker inspect --format="{{.Id}}" <image-name> | sed '/^[[:space:]]*$/d')
sudo docker exec -i -t ${api_image_id} /bin/bash
I need a specific container and make a script to extract some info from it in a quick sight.
Hope this would help others.
I realize this is a bit late, but I've had success with annotating a timestamp column with
@Column(name="timestamp", columnDefinition="TIMESTAMP DEFAULT CURRENT_TIMESTAMP")
This should also work with CURRENT_DATE
and CURRENT_TIME
. I'm using JPA/Hibernate with Oracle, so YMMV.
Here's the calling order:
app.config()

Here's a simple demo where you can watch each one executing (and experiment if you'd like).
From Angular's module docs:
Run blocks - get executed after the injector is created and are used to kickstart the application. Only instances and constants can be injected into run blocks. This is to prevent further system configuration during application run time.
Run blocks are the closest thing in Angular to the main method. A run block is the code which needs to run to kickstart the application. It is executed after all of the services have been configured and the injector has been created. Run blocks typically contain code which is hard to unit-test, and for this reason should be declared in isolated modules, so that they can be ignored in the unit-tests.
One situation where run blocks are used is during authentications.
go to the "Terminal" and just type

In my case it's running on port "5432" (default).

The marked answer is 100% fine, however, there are certain cases when the standard method is fooled by virtual cards (virtual box, ...). It's also often desirable to discard some network interfaces based on their speed (serial ports, modems, ...).
Here is a piece of code that checks for these cases:
/// <summary>
/// Indicates whether any network connection is available
/// Filter connections below a specified speed, as well as virtual network cards.
/// </summary>
/// <returns>
/// <c>true</c> if a network connection is available; otherwise, <c>false</c>.
/// </returns>
public static bool IsNetworkAvailable()
{
return IsNetworkAvailable(0);
}
/// <summary>
/// Indicates whether any network connection is available.
/// Filter connections below a specified speed, as well as virtual network cards.
/// </summary>
/// <param name="minimumSpeed">The minimum speed required. Passing 0 will not filter connection using speed.</param>
/// <returns>
/// <c>true</c> if a network connection is available; otherwise, <c>false</c>.
/// </returns>
public static bool IsNetworkAvailable(long minimumSpeed)
{
if (!NetworkInterface.GetIsNetworkAvailable())
return false;
foreach (NetworkInterface ni in NetworkInterface.GetAllNetworkInterfaces())
{
// discard because of standard reasons
if ((ni.OperationalStatus != OperationalStatus.Up) ||
(ni.NetworkInterfaceType == NetworkInterfaceType.Loopback) ||

If you just want the first number to match you can do it like this:
[item for item in a if item[0] == 1]
If you are just searching for tuples with 1 in them:
[item for item in a if 1 in item]
Below is a way I used to generate unique number always. Random function generates number and stores it in textfile then next time it checks it in file compares it and generate new unique number hence in this way there is always a new unique number.
public int GenerateRandomNo()
{
int _min = 0000;
int _max = 9999;
Random _rdm = new Random();
return _rdm.Next(_min, _max);
}
public int rand_num()
{
randnum = GenerateRandomNo();
string createText = randnum.ToString() + Environment.NewLine;
string file_path = System.IO.Path.GetDirectoryName(System.Windows.Forms.Application.ExecutablePath) + @"\Invoices\numbers.txt";
File.AppendAllText(file_path, createText);
int number = File.ReadLines(file_path).Count(); //count number of lines in file
System.IO.StreamReader file = new System.IO.StreamReader(file_path);
do
{
randnum = GenerateRandomNo();
}
while ((file.ReadLine()) == randnum.ToString());
file.Close();
return randnum;
}
Here is a function that takes as its arguments a DataFrame and a list of columns and coerces all data in the columns to numbers.
# df is the DataFrame, and column_list is a list of columns as strings (e.g ["col1","col2","col3"])
# dependencies: pandas
def coerce_df_columns_to_numeric(df, column_list):
df[column_list] = df[column_list].apply(pd.to_numeric, errors='coerce')
So, for your example:
import pandas as pd
def coerce_df_columns_to_numeric(df, column_list):
df[column_list] = df[column_list].apply(pd.to_numeric, errors='coerce')
a = [['a', '1.2', '4.2'], ['b', '70', '0.03'], ['x', '5', '0']]
df = pd.DataFrame(a, columns=['col1','col2','col3'])
coerce_df_columns_to_numeric(df, ['col2','col3'])
Do it in the code-behind by setting the text color initially to gray and adding event handlers for gaining and losing keyboard focus.
TextBox tb = new TextBox();
tb.Foreground = Brushes.Gray;
tb.Text = "Text";
tb.GotKeyboardFocus += new KeyboardFocusChangedEventHandler(tb_GotKeyboardFocus);
tb.LostKeyboardFocus += new KeyboardFocusChangedEventHandler(tb_LostKeyboardFocus);
Then the event handlers:
private void tb_GotKeyboardFocus(object sender, KeyboardFocusChangedEventArgs e)
{
if(sender is TextBox)
{
//If nothing has been entered yet.
if(((TextBox)sender).Foreground == Brushes.Gray)
{
((TextBox)sender).Text = "";
((TextBox)sender).Foreground = Brushes.Black;
}
}
}
private void tb_LostKeyboardFocus(object sender, KeyboardFocusChangedEventArgs e)
{
//Make sure sender is the correct Control.
if(sender is TextBox)
{
//If nothing was entered, reset default text.
if(((TextBox)sender).Text.Trim().Equals(""))
{
((TextBox)sender).Foreground = Brushes.Gray;
((TextBox)sender).Text = "Text";
}
}
}
Nothing. Just execute your query. If the connection has died, either your JDBC driver will reconnect (if it supports it, and you enabled it in your connection string--most don't support it) or else you'll get an exception.
If you check the connection is up, it might fall over before you actually execute your query, so you gain absolutely nothing by checking.
That said, a lot of connection pools validate a connection by doing something like SELECT 1
before handing connections out. But this is nothing more than just executing a query, so you might just as well execute your business query.
Where is your gcc
?
My gcc
is in "C:\Program Files\CodeBlocks\MinGW\bin\".
"C:\Program Files\CodeBlocks\MinGW\bin\gcc" -c "foo.c"
"C:\Program Files\CodeBlocks\MinGW\bin\gcc" "foo.o" -o "foo 01.exe"
$(element).on("click mousedown mouseup focus blur keydown change",function(e){
console.log(e);
});
That will get you a lot (but not all) of the information on if an event is fired... other than manually coding it like this, I can't think of any other way to do that.
RMDIR path_to_folder /S
ex. RMDIR "C:\tmp" /S
Note that you'll be prompted if you're really going to delete the "C:\tmp" folder. Combining it with /Q switch will remove the folder silently (ex. RMDIR "C:\tmp" /S /Q
)
The proper solution is the one provided by @Jojo.Lechelt.
However if you don't want to commit for any reason and still want to pull the changes,you may save your changes somewhere else,replace the conflicting file with HEAD revision and then pull.
Later you can paste your changes again and compare it with HEAD and incorporate other people changes into your file.
I guess you'll need absolute position
.vertical_banner {position:relative;}
#bottom_link{position:absolute; bottom:0;}
Maybe it's obvious for you guys but I scratched my head for a while because the folder didn't show up in the files app. I actually needed to store something in the folder. you could achieve this by
Most previous answers are correct and my answer is very similar to aaronasterling, you could also do 3 single quotations s1='''some very long string............'''
It depends of the language, and of the architecture you are using.
For example, in a php platform, you can format almost language with GeSHi
As bluish comments, GeSHi is a generic syntax highlighter, with no beautification feature. It is more used on the server side, and combine it with a beautification tool can be tricky, as illustrated with this GeSHi drupal ticket.
There is no direct option to export a single request from Postman.
You can create and export collections. Here is a link to help with that.
Regarding the single request thing, you can try a workaround. I tried with the RAW body parameters and it worked.
What you can do is,
I don't think Bass's answer is correct. Why touch the row margins? They have a negative margin to offset the column padding for the columns on the edge of the row. Messing with this will break any nested rows.
The answer is simple, just make the container padding equal to the gutter size:
e.g for default bootstrap:
.container {
padding-left:30px;
padding-right:30px;
}
For anyone looking for a complete explanation, I recommend you to take a look at Content Security Policy: https://www.html5rocks.com/en/tutorials/security/content-security-policy/.
"Code from https://mybank.com should only have access to https://mybank.com’s data, and https://evil.example.com should certainly never be allowed access. Each origin is kept isolated from the rest of the web"
XSS attacks are based on the browser's inability to distinguish your app's code from code downloaded from another website. So you must whitelist the content origins that you consider safe to download content from, using the Content-Security-Policy
HTTP header.
This policy is described using a series of policy directives, each of which describes the policy for a certain resource type or policy area. Your policy should include a default-src policy directive, which is a fallback for other resource types when they don't have policies of their own.
So, if you modify your tag to:
<meta http-equiv="Content-Security-Policy" content="default-src 'self' data: gap: https://ssl.gstatic.com 'unsafe-eval'; style-src 'self' 'unsafe-inline'; media-src *;**script-src 'self' http://onlineerp.solution.quebec 'unsafe-inline' 'unsafe-eval';** ">
You are saying that you are authorizing the execution of JavaScript code (script-src
)
from the origins 'self'
, http://onlineerp.solution.quebec
, 'unsafe-inline'
, 'unsafe-eval'
.
I guess that the first two are perfectly valid for your use case, I am a bit unsure about the other ones. 'unsafe-line'
and 'unsafe-eval'
pose a security problem, so you should not be using them unless you have a very specific need for them:
"If eval and its text-to-JavaScript brethren are completely essential to your application, you can enable them by adding 'unsafe-eval' as an allowed source in a script-src directive. But, again, please don’t. Banning the ability to execute strings makes it much more difficult for an attacker to execute unauthorized code on your site." (Mike West, Google)
I found the answer is git reset --merge
- it clears the conflicted cherry-pick attempt.
I always try to factor out complex boolean expressions into meaningful variables (you could probably think of better names based on what these columns are used for):
bool notColumnsABC = (columnname != a && columnname != b && columnname != c);
bool notColumnA2OrBoxIsChecked = ( columnname != A2 || checkbox.checked );
if ( notColumnsABC
&& notColumnA2OrBoxIsChecked )
{
"statement 1"
}

You can easily debug such things when you go through the generated CSS. In this case the pseudo-selector after conversion has to be attached to the class. Which is not the case. Use "&".
http://sass-lang.com/documentation/file.SASS_REFERENCE.html#parent-selector
.class {
margin:20px;
&:hover {
color:yellow;
}
}
T
must be defined within the scope in which you are working. Therefore, what you have posted will work if your class is generic on T
:
public class MyClass<T>
{
private List<T> newList;
public List<T> NewList
{
get{return newList;}
set{newList = value;}
}
}
Otherwise, you have to use a defined type.
EDIT: Per @lKashef's request, following is how to have a List property:
private List<int> newList;
public List<int> NewList
{
get{return newList;}
set{newList = value;}
}
This can go within a non-generic class.
Edit 2: In response to your second question (in your edit), I would not recommend using a list for this type of data handling (if I am understanding you correctly). I would put the user settings in their own class (or struct, if you wish) and have a property of this type on your original class:
public class UserSettings
{
string FirstName { get; set; }
string LastName { get; set; }
// etc.
}
public class MyClass
{
string MyClassProperty1 { get; set; }
// etc.
UserSettings MySettings { get; set; }
}
This way, you have named properties that you can reference instead of an arbitrary index in a list. For example, you can reference MySettings.FirstName
as opposed to MySettingsList[0]
.
Let me know if you have any further questions.
EDIT 3: For the question in the comments, your property would be like this:
public class MyClass
{
public List<KeyValuePair<string, string>> MySettings { get; set; }
}
EDIT 4: Based on the question's edit 2, following is how I would use this:
public class MyClass
{
// note that this type of property declaration is called an "Automatic Property" and
// it means the same thing as you had written (the private backing variable is used behind the scenes, but you don't see it)
public List<KeyValuePair<string, string> MySettings { get; set; }
}
public class MyConsumingClass
{
public void MyMethod
{
MyClass myClass = new MyClass();
myClass.MySettings = new List<KeyValuePair<string, string>>();
myClass.MySettings.Add(new KeyValuePair<string, string>("SomeKeyValue", "SomeValue"));
// etc.
}
}
You mentioned that "the property still won't appear in the object's instance," and I am not sure what you mean. Does this property not appear in IntelliSense? Are you sure that you have created an instance of MyClass
(like myClass.MySettings
above), or are you trying to access it like a static property (like MyClass.MySettings
)?
__FUNCTION__
is non standard, __func__
exists in C99 / C++11. The others (__LINE__
and __FILE__
) are just fine.
It will always report the right file and line (and function if you choose to use __FUNCTION__
/__func__
). Optimization is a non-factor since it is a compile time macro expansion; it will never affect performance in any way.
Set the text of the button by setting the innerHTML
var b = document.createElement('button');
b.setAttribute('content', 'test content');
b.setAttribute('class', 'btn');
b.innerHTML = 'test value';
var wrapper = document.getElementById('divWrapper');
wrapper.appendChild(b);
From the Java EE documentation:
public abstract boolean unique
(Optional) Whether the property is a unique key. This is a shortcut for the UniqueConstraint annotation at the table level and is useful for when the unique key constraint is only a single field. This constraint applies in addition to any constraint entailed by primary key mapping and to constraints specified at the table level.
See doc
UPDATE R
SET R.status = '0'
FROM dbo.ProductReviews AS R
INNER JOIN dbo.products AS P
ON R.pid = P.id
WHERE R.id = '17190'
AND P.shopkeeper = '89137';
This:
document.getElementById('myField').onblur();
works because your element (the <input>
) has an attribute called "onblur" whose value is a function. Thus, you can call it. You're not telling the browser to simulate the actual "blur" event, however; there's no event object created, for example.
Elements do not have a "blur" attribute (or "method" or whatever), so that's why the first thing doesn't work.
Use the Arrays.sort() method, the lowest value will be element0.
In terms of performance, this should not be expensive since the sort operation is already optimised. Also has the advantage of being concise.
private int min(int ... value) {
Arrays.sort(value);
return value[0];
}
Proof of concept
int[] intArr = {12, 5, 6, 9, 44, 28, 1, 4, 18, 2, 66, 13, 1, 33, 74, 12,
5, 6, 9, 44, 28, 1, 4, 18, 2, 66, 13};
// Sorting approach
long startTime = System.currentTimeMillis();
int minVal = min(intArr);
long endTime = System.currentTimeMillis();
System.out.println("Sorting: Min => " + minVal + " took => " + (endTime -
startTime));
System.out.println(startTime + " " + endTime);
System.out.println(" ");
// Scanning approach
minVal = 100;
startTime = System.currentTimeMillis();
for(int val : intArr) {
if (val < minVal)
minVal = val;
}
endTime = System.currentTimeMillis();
System.out.println("Iterating: Min => " + minVal + " took => " + (endTime
- startTime));
System.out.println(startTime + " " + endTime);
In Java 8:
Arrays.sort(files, (a, b) -> Long.compare(a.lastModified(), b.lastModified()));
I approached this in a slightly different way and it worked for me;
I needed to remove secure_links
from my table that referenced the conditions
table where there were no longer any condition rows left. A housekeeping script basically. This gave me the error - You cannot specify target table for delete.
So looking here for inspiration I came up with the below query and it works just fine.
This is because it creates a temporary table sl1
that is used as the reference for the DELETE.
DELETE FROM `secure_links` WHERE `secure_links`.`link_id` IN
(
SELECT
`sl1`.`link_id`
FROM
(
SELECT
`sl2`.`link_id`
FROM
`secure_links` AS `sl2`
LEFT JOIN `conditions` ON `conditions`.`job` = `sl2`.`job`
WHERE
`sl2`.`action` = 'something' AND
`conditions`.`ref` IS NULL
) AS `sl1`
)
Works for me.
Just want to add this here, since people still return to this question even after many time. Of course it's bad practice, but it's still possible (in principle) to do what author wants with:
class SpecialDerived : Derived
{
public override void Say()
{
Console.WriteLine("Called from Special Derived.");
var ptr = typeof(Base).GetMethod("Say").MethodHandle.GetFunctionPointer();
var baseSay = (Action)Activator.CreateInstance(typeof(Action), this, ptr);
baseSay();
}
}
I don't know if this will help with your current predicament as this is a recent feature, but you can specify the visibility of symbols in a global manner. Passing -fvisibility=hidden -fvisibility-inlines-hidden
at compilation can help the linker to later get rid of unneeded symbols. If you're producing an executable (as opposed to a shared library) there's nothing more to do.
More information (and a fine-grained approach for e.g. libraries) is available on the GCC wiki.
You could implement a JavaScript block which contains a function with your needs.
<div style="position: absolute; left: 10px; top: 40px;">
<img src="logg.png" width="114" height="38" onclick="DoSomething();" />
</div>

You can move you read.aspx view to Shared folder. It is standard way in such circumstances
You can template a struct as well as a class. However you can't template a typedef. So template<typename T> struct array {...};
works, but template<typename T> typedef struct {...} array;
does not. Note that there is no need for the typedef trick in C++ (you can use structs without the struct
modifier just fine in C++).
Again if you don't want to use bodyParser, the following works:
var express = require('express');
var http = require('http');
var app = express();
app.use(express.static('./public'));
app.configure(function(){
app.use(express.methodOverride());
app.use(express.multipart({
uploadDir: './uploads',
keepExtensions: true
}));
});
app.use(app.router);
app.get('/upload', function(req, res){
// Render page with upload form
res.render('upload');
});
app.post('/upload', function(req, res){
// Returns json of uploaded file
res.json(req.files);
});
http.createServer(app).listen(3000, function() {
console.log('App started');
});

I haven't ever seen such a thing, but there is this dev tool that includes a syntax checker for oracle, mysql, db2, and sql server... http://www.sqlparser.com/index.php
However this seems to be just the library. You'd need to build an app to leverage the parser to do what you want. And the Enterprise edition that includes all of the databases would cost you $450... ouch!
EDIT: And, after saying that - it looks like someone might already have done what you want using that library: http://www.wangz.net/cgi-bin/pp/gsqlparser/sqlpp/sqlformat.tpl
The online tool doesn't automatically check against each DB though, you need to run each manually. Nor can I say how good it is at checking the syntax. That you'd need to investigate yourself.
Try like this:
list($width, $height) = getimagesize('path_to_image');
Make sure that:
Also try to prefix path with $_SERVER["DOCUMENT_ROOT"]

There is an undocumented method called device_lib.list_local_devices()
that enables you to list the devices available in the local process. (N.B. As an undocumented method, this is subject to backwards incompatible changes.) The function returns a list of DeviceAttributes
protocol buffer objects. You can extract a list of string device names for the GPU devices as follows:
from tensorflow.python.client import device_lib
def get_available_gpus():
local_device_protos = device_lib.list_local_devices()
return [x.name for x in local_device_protos if x.device_type == 'GPU']
Note that (at least up to TensorFlow 1.4), calling device_lib.list_local_devices()
will run some initialization code that, by default, will allocate all of the GPU memory on all of the devices (GitHub issue). To avoid this, first create a session with an explicitly small per_process_gpu_fraction
, or allow_growth=True
, to prevent all of the memory being allocated. See this question for more details.
There is one more way to solve this problem. 1)Go to Project Explorer. Go to the target folder of your project, right-click and delete the target folder. 2)Right-click on your project, select run as Maven Build. 3)After you get Build Success on the console; right click on the project folder and select refresh. After performing the above steps, try to run your project.Your problem should be solved now.

For the sake of others who are wondering on how to get to this window. Here's how:
You can access this by clicking on Select Run/Debug Configurations
(to the left of ) and going to the Edit Configurations
. A
gif provided for clarity.
It depends on the jQuery selector that you use. Since id
should be unique within the DOM, the first one would be simple:
$('#Comanda').hide();
The second one might require something more, depending on the other elements and how to uniquely identify it. If the name
of that particular input
is unique, then this would work:
$('input[name="Vizualizeaza"]').hide();
window.location.hash = 'something';
That is just plain JavaScript.
Your comment...
Hi, what I really need is to add only the hash... something like this:
window.location.hash = '#';
but in this way nothing is added.
Try this...
window.location = '#';
Also, don't forget about the window.location.replace()
method.
Very near to TheEye answer, but I change a little thing to make it work:
var num = 192.16;_x000D_
_x000D_
console.log( Math.ceil(num * 10) / 10 );
_x000D_
You can create an array of pointers.
Car** mycars = new Car*[userInput];
for (int i=0; i<userInput; i++){
mycars[i] = new Car(...);
}
...
for (int i=0; i<userInput; i++){
delete mycars[i];
}
delete [] mycars;
or
Car() constructor does not need to be public. Add a static method to your class that builds an array:
static Car* makeArray(int length){
return new Car[length];
}
You can just do that too, it seems to work well too.
sc create "Servicename" binPath= "Path\To\your\App.exe" DisplayName= "My Custom Service"
You can open the registry and add a string named Description in your service's registry key to add a little more descriptive information about it. It will be shown in services.msc.
If you are using C99 then you can use the _Bool
type. No #include
s are necessary. You do need to treat it like an integer, though, where 1
is true
and 0
is false
.
You can then define TRUE
and FALSE
.
_Bool this_is_a_Boolean_var = 1;
//or using it with true and false
#define TRUE 1
#define FALSE 0
_Bool var = TRUE;
In .NET you can use grouping to your advantage like this:
http://regexhero.net/tester/?id=65b32601-2326-4ece-912b-6dcefd883f31
You'll notice that:
(ABC)|(.)
Will grab everything except ABC in the 2nd group. Parenthesis surround each group. So (ABC) is group 1 and (.) is group 2.
So you just grab the 2nd group like this in a replace:
$2
Or in .NET look at the Groups collection inside the Regex class for a little more control.
You should be able to do something similar in most other regex implementations as well.
UPDATE: I found a much faster way to do this here: http://regexhero.net/tester/?id=997ce4a2-878c-41f2-9d28-34e0c5080e03
It still uses grouping (I can't find a way that doesn't use grouping). But this method is over 10X faster than the first.

Use the first:
std::sort(numbers.begin(), numbers.end(), std::greater<int>());
It's explicit of what's going on - less chance of misreading rbegin
as begin
, even with a comment. It's clear and readable which is exactly what you want.
Also, the second one may be less efficient than the first given the nature of reverse iterators, although you would have to profile it to be sure.

Just wanted to throw my specific case in here. Might help someone down the line.
I was using the directive in my Android UI XML like this:
Parent view:
<FrameLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:tag="home_phone"
android:background="@color/colorPrimary">
...
<include
layout="@layout/retry_button"
android:visibility="gone" />
Child view (retry_button):
<com.foo.RetryButton
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/retry"
android:layout_gravity="center"
android:orientation="vertical"
android:layout_width="100dp"
android:layout_height="140dp">
.findViewById(R.id.retry) would always return null. But, if I moved the ID from the child view into the include tag, it started working.
Fixed parent:
<FrameLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:tag="home_phone"
android:background="@color/colorPrimary">
...
<include
layout="@layout/retry_button"
android:id="@+id/retry"
android:visibility="gone" />
Fixed child:
<com.foo.RetryButton
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_gravity="center"
android:orientation="vertical"
android:layout_width="100dp"
android:layout_height="140dp">
I generally agree with solutions given above. Namely with:
for
-loop (2 and more lines)while
counter (3 and more lines)__nonzero__
implementation (many more lines) If one is to define an object as in #3 I would recommend implementing protocol for with keyword or apply contextlib.
Further I propose yet another solution. It is a 3 liner and is not of supreme elegance, but it uses itertools package and thus might be of an interest.
from itertools import (chain, repeat)
times = chain(repeat(True, 2), repeat(False))
while next(times):
print 'do stuff!'
In these example 2 is the number of times to iterate the loop. chain is wrapping two repeat iterators, the first being limited but the second is infinite. Remember that these are true iterator objects, hence they do not require infinite memory. Obviously this is much slower then solution #1. Unless written as a part of a function it might require a clean up for times variable.
A JavaScript solution for Internet Explorer is:
onselectstart="return false;"
Use the command as
java -classpath ".;C:\MyLibs\a\*;D:\MyLibs\b\*" <your-class-name>
The above command will set the mentioned paths to classpath only once for executing the class named TestClass.
If you want to execute more then one classes, then you can follow this
set classpath=".;C:\MyLibs\a\*;D:\MyLibs\b\*"
After this you can execute as many classes as you want just by simply typing
java <your-class-name>
The above command will work till you close the command prompt. But after closing the command prompt, if you will reopen the command prompt and try to execute some classes, then you have to again set the classpath with the help of any of the above two mentioned methods.(First method for executing one class and second one for executing more classes)
If you want to set the classpth only once so that it could work for everytime, then do as follows
1. Right click on "My Computer" icon
2. Go to the "properties"
3. Go to the "Advanced System Settings" or "Advance Settings"
4. Go to the "Environment Variable"
5. Create a new variable at the user variable by giving the information as below
a. Variable Name- classpath
b. Variable Value- .;C:\program files\jdk 1.6.0\bin;C:\MyLibs\a\';C:\MyLibs\b\*
6.Apply this and you are done.
Remember this will work every time. You don't need to explicitly set the classpath again and again.
NOTE: If you want to add some other libs after some day, then don't forget to add a semi-colon at the end of the "variable-value" of the "Environment Variable" and then type the path of your new libs after the semi-colon. Because semi-colon separates the paths of different directories.
Hope this will help you.
Controller not supposed to be called from view. That's the whole idea of MVC - clear separation of concerns.
If you need to call controller from View - you are doing something wrong. Time for refactoring.
As a slight improvement over the other answers, you can do the mkdir
and chmod
as a single operation using mkdir
's -m
switch.
$ mkdir -m 700 ${HOME}/.ssh
From a Linux system
$ mkdir --help
Usage: mkdir [OPTION]... DIRECTORY...
Create the DIRECTORY(ies), if they do not already exist.
Mandatory arguments to long options are mandatory for short options too.
-m, --mode=MODE set file mode (as in chmod), not a=rwx - umask

The solution from Robert MacLean with highest number of votes is 99% correct. But the only addition someone might require, as I did, is whenever you need to open up this jQuery dialog, do not forget to append it to parent. Like below:
var dlg = $('#questionPopup').dialog( 'open');
dlg.parent().appendTo($("form:first"));
UML Studio does this quite well in my experience, and will run in "freeware mode" for small projects.
-Confirm
is a switch in most PowerShell cmdlets that forces the cmdlet to ask for user confirmation. What you're actually looking for is the Read-Host
cmdlet:
$confirmation = Read-Host "Are you Sure You Want To Proceed:"
if ($confirmation -eq 'y') {
# proceed
}
or the PromptForChoice()
method of the host user interface:
$title = 'something'
$question = 'Are you sure you want to proceed?'
$choices = New-Object Collections.ObjectModel.Collection[Management.Automation.Host.ChoiceDescription]
$choices.Add((New-Object Management.Automation.Host.ChoiceDescription -ArgumentList '&Yes'))
$choices.Add((New-Object Management.Automation.Host.ChoiceDescription -ArgumentList '&No'))
$decision = $Host.UI.PromptForChoice($title, $question, $choices, 1)
if ($decision -eq 0) {
Write-Host 'confirmed'
} else {
Write-Host 'cancelled'
}
Edit:
As M-pixel pointed out in the comments the code could be simplified further, because the choices can be passed as a simple string array.
$title = 'something'
$question = 'Are you sure you want to proceed?'
$choices = '&Yes', '&No'
$decision = $Host.UI.PromptForChoice($title, $question, $choices, 1)
if ($decision -eq 0) {
Write-Host 'confirmed'
} else {
Write-Host 'cancelled'
}
I had the same question except that I wanted to combine the criteria into an OR condition. The format given by Wouter Overmeire combines the criteria into an AND condition such that both must be satisfied:
In [96]: df
Out[96]:
A B C D
a 1 4 9 1
b 4 5 0 2
c 5 5 1 0
d 1 3 9 6
In [99]: df[(df.A == 1) & (df.D == 6)]
Out[99]:
A B C D
d 1 3 9 6
But I found that, if you wrap each condition in (... == True)
and join the criteria with a pipe, the criteria are combined in an OR condition, satisfied whenever either of them is true:
df[((df.A==1) == True) | ((df.D==6) == True)]
I think the most simple way is .iloc[[0, -1]]
.
df = pd.DataFrame({'a':range(1,5), 'b':['a','b','c','d']})
df2 = df.iloc[[0, -1]]
print df2
a b
0 1 a
3 4 d

JEP 158 introduces a common logging system for all components of the JVM which will change (and IMO simplify) how logging works with GC. JEP 158 added a new command-line option to control logging from all components of the JVM:
-Xlog
For example, the following option:
-Xlog:gc
will log messages tagged with gc
tag using info
level to stdout
. Or this one:
-Xlog:gc=debug:file=gc.txt:none
would log messages tagged with gc
tag using debug
level to a file called gc.txt
with no decorations. For more detailed discussion, you can checkout the examples in the JEP page.

Two very different types of Pipes Angular - Pipes and RxJS - Pipes
A pipe takes in data as input and transforms it to a desired output. In this page, you'll use pipes to transform a component's birthday property into a human-friendly date.
import { Component } from '@angular/core';
@Component({
selector: 'app-hero-birthday',
template: `<p>The hero's birthday is {{ birthday | date }}</p>`
})
export class HeroBirthdayComponent {
birthday = new Date(1988, 3, 15); // April 15, 1988
}
Observable operators are composed using a pipe method known as Pipeable Operators. Here is an example.
import {Observable, range} from 'rxjs';
import {map, filter} from 'rxjs/operators';
const source$: Observable<number> = range(0, 10);
source$.pipe(
map(x => x * 2),
filter(x => x % 3 === 0)
).subscribe(x => console.log(x));
The output for this in the console would be the following:
0
6
12
18
For any variable holding an observable, we can use the .pipe() method to pass in one or multiple operator functions that can work on and transform each item in the observable collection.
So this example takes each number in the range of 0 to 10, and multiplies it by 2. Then, the filter function to filter the result down to only the odd numbers.
I think the example is wrong - javax.sql.DataSource
doesn't have these properties either. Your DataSource
needs to be of the type org.apache.derby.jdbc.ClientDataSource
, which should have those properties.
You can also force a push by adding the + symbol before your branch name.

Swift 4 solution
Three simple steps:
Change the constraints, e.g.:
heightAnchor.constant = 50
Tell the containing view
that its layout is dirty and that the autolayout should recalculate the layout:
self.view.setNeedsLayout()
In animation block tell the layout to recalculate the layout, which is equivalent of setting the frames directly (in this case the autolayout will set the frames):
UIView.animate(withDuration: 0.5) {
self.view.layoutIfNeeded()
}
Complete simplest example:
heightAnchor.constant = 50
self.view.setNeedsLayout()
UIView.animate(withDuration: 0.5) {
self.view.layoutIfNeeded()
}
Sidenote
There is an optional 0th step - before changing the constraints you might want to call self.view.layoutIfNeeded()
to make sure that the starting point for the animation is from the state with old constraints applied (in case there were some other constraints changes that should not be included in animation):
otherConstraint.constant = 30
// this will make sure that otherConstraint won't be animated but will take effect immediately
self.view.layoutIfNeeded()
heightAnchor.constant = 50
self.view.setNeedsLayout()
UIView.animate(withDuration: 0.5) {
self.view.layoutIfNeeded()
}
Since with iOS 10 we got a new animating mechanism - UIViewPropertyAnimator
, we should know that basically the same mechanism applies to it. The steps are basically the same:
heightAnchor.constant = 50
self.view.setNeedsLayout()
let animator = UIViewPropertyAnimator(duration: 0.5, timingParameters: UICubicTimingParameters(animationCurve: .linear))
animator.addAnimations {
self.view.layoutIfNeeded()
}
animator.startAnimation()
Since animator
is an encapsulation of the animation, we can keep reference to it and call it later. However, since in the animation block we just tell the autolayout to recalculate the frames, we have to change the constraints before calling startAnimation
. Therefore something like this is possible:
// prepare the animator first and keep a reference to it
let animator = UIViewPropertyAnimator(duration: 0.5, timingParameters: UICubicTimingParameters(animationCurve: .linear))
animator.addAnimations {
self.view.layoutIfNeeded()
}
// at some other point in time we change the constraints and call the animator
heightAnchor.constant = 50
self.view.setNeedsLayout()
animator.startAnimation()
The order of changing constraints and starting an animator is important - if we just change the constraints and leave our animator for some later point, the next redraw cycle can invoke autolayout recalculation and the change will not be animated.
Also, remember that a single animator is non-reusable - once you run it, you cannot "rerun" it. So I guess there is not really a good reason to keep the animator around, unless we use it for controlling an interactive animation.

I've made a jQuery plugin for the equivalent of
<pre>
<?php echo print_r($data) ?>
</pre>
You can download it at https://github.com/tomasvanrijsse/jQuery.dump
Just Follow Simple 1-2-3 Steps :
1) Go to Taskbar
2) Click on WAMP icon (Left Click)
3) Now Go to Apache > Services > Apache Module and check Rewrite_module is enable or not ! if its not then click on it ! WAMP will be automatically restarted and you're done !
If you are using bash with the extglob option enabled, you can remove just the trailing whitespace via:
shopt -s extglob
COMMAND=$'\nRE BOOT\r \n'
echo "|${COMMAND%%*([$'\t\r\n '])}|"
This outputs:
|
RE BOOT|
Or replace %% with ## to replace just the leading whitespace.
This may be a hack:
as in question In Unix / Bash, is "xargs -p" a good way to prompt for confirmation before running any command?
we can using xargs
to do the job:
echo ssh://[email protected]//somepath/morepath | xargs -p hg push
of course, this will be set as an alias, like hgpushrepo
Example:
$ echo foo | xargs -p ls -l
ls -l foo?...y
-rw-r--r-- 1 mikelee staff 0 Nov 23 10:38 foo
$ echo foo | xargs -p ls -l
ls -l foo?...n
$
When using Python 3 the empty lines can be avoid by using the codecs module. As stated in the documentation, files are opened in binary mode so no change of the newline kwarg is necessary. I was running into the same issue recently and that worked for me:
with codecs.open( csv_file, mode='w', encoding='utf-8') as out_csv:
csv_out_file = csv.DictWriter(out_csv)
To uninstall Anaconda open a terminal window:
rm -rf ~/anaconda
~/.bash_profile
and remove the anaconda directory from your PATH
environment variable.Note: You may need to edit .bashrc
and/or .profile
files instead of .bash_profile
Remove the following hidden files and directories, which may have been created in the home directory:
.condarc
.conda
.continuum
Use:
rm -rf ~/.condarc ~/.conda ~/.continuum
There is no explicit way to change the favicon globally using CSS that I know of. But you can use a simple trick to change it on the fly.
First just name, or rename, the favicon to "favicon.ico" or something similar that will be easy to remember, or is relevant for the site you're working on. Then add the link to the favicon in the head as you usually would. Then when you drop in a new favicon just make sure it's in the same directory as the old one, and that it has the same name, and there you go!
It's not a very elegant solution, and it requires some effort. But dropping in a new favicon in one place is far easier than doing a find and replace of all the links, or worse, changing them manually. At least this way doesn't involve messing with the code.
Of course dropping in a new favicon with the same name will delete the old one, so make sure to backup the old favicon in case of disaster, or if you ever want to go back to the old design.

Run dos2unix or similar utility on it to remove the carriage returns (^M).
This message indicates that your file has dos-style lineendings:
-bash: /backup/backup.sh: /bin/bash^M: bad interpreter: No such file or directory
Utilities like dos2unix
will fix it:
dos2unix <backup.bash >improved-backup.sh
Or, if no such utility is installed, you can accomplish the same thing with translate:
tr -d "\015\032" <backup.bash >improved-backup.sh

What do I need to do to make this function wait for the result of the promise?
Use async/await
(NOT Part of ECMA6, but
available for Chrome, Edge, Firefox and Safari since end of 2017, see canIuse)
MDN
async function waitForPromise() {
// let result = await any Promise, like:
let result = await Promise.resolve('this is a sample promise');
}
Added due to comment: An async function always returns a Promise, and in TypeScript it would look like:
async function waitForPromise(): Promise<string> {
// let result = await any Promise, like:
let result = await Promise.resolve('this is a sample promise');
}
You may want to use one of two possible searches while working with list of strings:
if list element is equal to an item ('example' is in ['one','example','two']):
if item in your_list: some_function_on_true()
'ex' in ['one','ex','two'] => True
'ex_1' in ['one','ex','two'] => False
if list element is like an item ('ex' is in ['one,'example','two'] or 'example_1' is in ['one','example','two']):
matches = [el for el in your_list if item in el]
or
matches = [el for el in your_list if el in item]
then just check len(matches)
or read them if needed.
To call the function on click of some html element (control).
$('#controlID').click(myFunction);
You will need to ensure you bind the event when your html element is ready on which you binding the event. You can put the code in document.ready
$(document).ready(function(){
$('#controlID').click(myFunction);
});
You can use anonymous function to bind the event to the html element.
$(document).ready(function(){
$('#controlID').click(function(){
$.messager.show({
title:'My Title',
msg:'The message content',
showType:'fade',
style:{
right:'',
bottom:''
}
});
});
});
If you want to bind click with many elements you can use class selector
$('.someclass').click(myFunction);
Edit based on comments by OP, If you want to call function under some condition
You can use if for conditional execution, for example,
if(a == 3)
myFunction();
Something like this worked for me.

You won't see a simple answer because there isn't one.
First, Unicode doesn't contain "every character from every language", although it sure does try.
Unicode itself is a mapping, it defines codepoints and a codepoint is a number, associated with usually a character. I say usually because there are concepts like combining characters. You may be familiar with things like accents, or umlauts. Those can be used with another character, such as an a
or a u
to create a new logical character. A character therefore can consist of 1 or more codepoints.
To be useful in computing systems we need to choose a representation for this information. Those are the various unicode encodings, such as utf-8, utf-16le, utf-32 etc. They are distinguished largely by the size of of their codeunits. UTF-32 is the simplest encoding, it has a codeunit that is 32bits, which means an individual codepoint fits comfortably into a codeunit. The other encodings will have situations where a codepoint will need multiple codeunits, or that particular codepoint can't be represented in the encoding at all (this is a problem for instance with UCS-2).
Because of the flexibility of combining characters, even within a given encoding the number of bytes per character can vary depending on the character and the normalization form. This is a protocol for dealing with characters which have more than one representation (you can say "an 'a' with an accent"
which is 2 codepoints, one of which is a combining char or "accented 'a'"
which is one codepoint).
An easy approach is to leverage this code:
<a href="javascript:void(0);">Link Title</a>
This approach doesn't force a page refresh, so the scrollbar stays in place. Also, it allows you to programmatically change the onclick event and handle client side event binding using jQuery.
For these reasons, the above solution is better than:
<a href="javascript:myClickHandler();">Link Title</a>
<a href="#" onclick="myClickHandler(); return false;">Link Title</a>
where the last solution will avoid the scroll-jump issue if and only if the myClickHandler method doesn't fail.
The functionality of creating SQL Agent Jobs is not available in SQL Server Express Edition. An alternative is to execute a batch file that executes a SQL script using Windows Task Scheduler.
In order to do this first create a batch file named sqljob.bat
sqlcmd -S servername -U username -P password -i <path of sqljob.sql>
Replace the servername
, username
, password
and path
with yours.
Then create the SQL Script file named sqljob.sql
USE [databasename]
--T-SQL commands go here
GO
Replace the [databasename]
with your database name. The USE
and GO
is necessary when you write the SQL script.
sqlcmd
is a command-line utility to execute SQL scripts. After creating these two files execute the batch file using Windows Task Scheduler.
NB: An almost same answer was posted for this question before. But I felt it was incomplete as it didn't specify about login information using sqlcmd
.
Here's a simple example: how many elements in a set. (there are better ways to count things, but this is a nice simple recursive example.)
First, we need two rules:
Suppose you have a set like this: [x x x]. let's count how many items there are.
We can represent this as:
count of [x x x] = 1 + count of [x x]
= 1 + (1 + count of [x])
= 1 + (1 + (1 + count of []))
= 1 + (1 + (1 + 0)))
= 1 + (1 + (1))
= 1 + (2)
= 3
When applying a recursive solution, you usually have at least 2 rules:
If we translate the above to pseudocode, we get:
numberOfItems(set)
if set is empty
return 0
else
remove 1 item from set
return 1 + numberOfItems(set)
There's a lot more useful examples (traversing a tree, for example) which I'm sure other people will cover.
WOFF 2.0, based on the Brotli compression algorithm and other improvements over WOFF 1.0 giving more than 30 % reduction in file size, is supported in Chrome, Opera, and Firefox.
http://en.wikipedia.org/wiki/Web_Open_Font_Format http://en.wikipedia.org/wiki/Brotli
http://sth.name/2014/09/03/Speed-up-webfonts/ has an example on how to use it.
Basically you add a src url to the woff2 file and specify the woff2 format. It is important to have this before the woff-format: the browser will use the first format that it supports.
If you want to pretty print the data frames, then you can use tabulate package.
import pandas as pd
import numpy as np
from tabulate import tabulate
def pprint_df(dframe):
print tabulate(dframe, headers='keys', tablefmt='psql', showindex=False)
df = pd.DataFrame({'col1': np.random.randint(0, 100, 10),
'col2': np.random.randint(50, 100, 10),
'col3': np.random.randint(10, 10000, 10)})
pprint_df(df)
Specifically, the showindex=False
, as the name says, allows you to not show index. The output would look as follows:
+--------+--------+--------+
| col1 | col2 | col3 |
|--------+--------+--------|
| 15 | 76 | 5175 |
| 30 | 97 | 3331 |
| 34 | 56 | 3513 |
| 50 | 65 | 203 |
| 84 | 75 | 7559 |
| 41 | 82 | 939 |
| 78 | 59 | 4971 |
| 98 | 99 | 167 |
| 81 | 99 | 6527 |
| 17 | 94 | 4267 |

The problem here is that you cannot define the background color using a color selector, you need a drawable selector. So, the necessary changes would look like this:
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item
android:state_pressed="true"
android:drawable="@drawable/selected_state" />
</selector>
You would also need to move that resource to the drawable
directory where it would make more sense since it's not a color selector per se.
Then you would have to create the res/drawable/selected_state.xml
file like this:
<?xml version="1.0" encoding="UTF-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle">
<solid android:color="@color/semitransparent_white" />
</shape>
and finally, you would use it like this:
android:background="@drawable/selector"
Note: the reason why the OP was getting an image resource drawn is probably because he tried to just reference his resource that was still in the color directory but using @drawable
so he ended up with an ID collision, selecting the wrong resource.
Hope this can still help someone even if the OP probably has, I hope, solved his problem by now.

You can do injection on Directives, and it looks just like it does everywhere else.
app.directive('changeIt', ['myData', function(myData){
return {
restrict: 'C',
link: function (scope, element, attrs) {
scope.name = myData.name;
}
}
}]);
There are two options. The first (and better) one is using the Fetch as Google option in Webmaster Tools that Mike Flynn commented about. Here are detailed instructions:
With the option above, as long as every page can be reached from some link on the initial page or a page that it links to, Google should recrawl the whole thing. If you want to explicitly tell it a list of pages to crawl on the domain, you can follow the directions to submit a sitemap.
Your second (and generally slower) option is, as seanbreeden pointed out, submitting here: http://www.google.com/addurl/
Update 2019:
I think you conclusions are correct but not accurate.
As the docs indicates, socket.recv
is majorly focused on the network buffers.
When socket is blocking, socket.recv
will return as long as the network buffers have bytes. If bytes in the network buffers are more than socket.recv
can handle, it will return the maximum number of bytes it can handle. If bytes in the network buffers are less than socket.recv
can handle, it will return all the bytes in the network buffers.

Python string comparison is lexicographic:
From Python Docs: http://docs.python.org/reference/expressions.html
Strings are compared lexicographically using the numeric equivalents (the result of the built-in function ord()) of their characters. Unicode and 8-bit strings are fully interoperable in this behavior.
Hence in your example, 'abc' < 'bac'
, 'a' comes before (less-than) 'b' numerically (in ASCII and Unicode representations), so the comparison ends right there.
Well, let's assume an example,
import java.io.File;
import java.io.IOException;
public class DeleteDirectory
{
private static final String folder = "D:/project/java";
public static void main(String[] args) throws IOException
{
File fl = new File(folder);
if(!fl.exists()) // checking if directory exists
{
System.out.println("Sorry!! directory doesn't exist.");
}
else
{
DeleteDirectory dd = new DeleteDirectory();
dd.deleteDirectory(fl);
}
}
public void deleteDirectory(File file) throws IOException
{
if(file.isDirectory())
{
if(file.list().length == 0)
{
deleteEmptyDirectory(file); // here if directory is empty delete we are deleting
}
else
{
File fe[] = file.listFiles();
for(File deleteFile : fe)
{
deleteDirectory(deleteFile); // recursive call
}
if(file.list().length == 0)
{
deleteEmptyDirectory(file);
}
}
}
else
{
file.delete();
System.out.println("File deleted : " + file.getAbsolutePath());
}
}
private void deleteEmptyDirectory(File fi)
{
fi.delete();
System.out.println("Directory deleted : " + fi.getAbsolutePath());
}
}

A generic piece of code that will work for multiple columns. This can also be used if there is a need to conditionally implement search functionality in the application.
search_key = "abc"
search_args = [col.ilike('%%%s%%' % search_key) for col in ['col1', 'col2', 'col3']]
query = Query(table).filter(or_(*search_args))
session.execute(query).fetchall()
Note: the %%
are important to skip % formatting the query.
It's this easy:
update my_table
set path = replace(path, 'oldstring', 'newstring')
In case of SQL Server, this should work

You can use:
$(window).unload(function() {
//do something
}
Unload() is deprecated in jQuery version 1.8, so if you use jQuery > 1.8 you can use even beforeunload instead.
The beforeunload event fires whenever the user leaves your page for any reason.
$(window).on("beforeunload", function() {
return confirm("Do you really want to close?");
})

find /I "AcPrfMgrSvc" %COMPUTERNAME%_START.TXT >nul
IF ERRORLEVEL 0 EXIT
IF ERRORLEVEL 1 NET START "AcPrfMgrSvc"
The Groovy way to do this is
def list = []
list << new MyType(...)
which creates a list and uses the overloaded leftShift
operator to append an item
See the Groovy docs on Lists for lots of examples.
You can get the count by the below query (without * or any column names).
select from table_name;
Real life example; find all but not current user:
var players = Players.find({ my_x: player.my_x, my_y: player.my_y, userId: {$ne: Meteor.userId()} });
I don't know if it is help. Create an AVD for a tablet-type device: Set the target to "Android 3.0" and the skin to "WXGA" (the default skin). You can check this site. http://developer.android.com/guide/practices/optimizing-for-3.0.html
You want the php function "asort":
http://php.net/manual/en/function.asort.php
it sorts the array, maintaining the index associations.
Edit: I've just noticed you're using a standard array (non-associative). if you're not fussed about preserving index associations, use sort():
Instead of faking a Boolean and leaving a trap for future readers, why not just use a better value than true and false?
For example:
build_state=success
if something-horrible; then
build_state=failed
fi
if [[ "$build_state" == success ]]; then
echo go home; you are done
else
echo your head is on fire; run around in circles
fi
You could try, div tag will auto fit height with content inside:
height: fit-content;
You can use PdfBox from Apache which is simple to use and has good performance.
Here is an example of extracting text from a PDF file (you can read more here) :
import java.io.*;
import org.apache.pdfbox.pdmodel.*;
import org.apache.pdfbox.util.*;
public class PDFTest {
public static void main(String[] args){
PDDocument pd;
BufferedWriter wr;
try {
File input = new File("C:\\Invoice.pdf"); // The PDF file from where you would like to extract
File output = new File("C:\\SampleText.txt"); // The text file where you are going to store the extracted data
pd = PDDocument.load(input);
System.out.println(pd.getNumberOfPages());
System.out.println(pd.isEncrypted());
pd.save("CopyOfInvoice.pdf"); // Creates a copy called "CopyOfInvoice.pdf"
PDFTextStripper stripper = new PDFTextStripper();
wr = new BufferedWriter(new OutputStreamWriter(new FileOutputStream(output)));
stripper.writeText(pd, wr);
if (pd != null) {
pd.close();
}
// I use close() to flush the stream.
wr.close();
} catch (Exception e){
e.printStackTrace();
}
}
}
UPDATE:
You can get the text using PDFTextStripper:
PDFTextStripper reader = new PDFTextStripper();
String pageText = reader.getText(pd); // PDDocument object created
I had the same problem, also in my XCTestCase
files, but not in the regular project files.
To get rid of the:
Use of unresolved identifier 'PrimeNumberModel'
I needed to import
the base module in the test file. In my case, my target is called 'myproject' and I added import myproject
and the class was recognised.
