I have been using the latter for a lot of nice lightweight animations. You can use it crossfade two views, or fade one in in front of another, or fade it out. You can shoot a view over another like a banner, you can make a view stretch or shrink... I'm getting a lot of mileage out of beginAnimation
/commitAnimations
.
Don't think that all you can do is:
[UIView setAnimationTransition:UIViewAnimationTransitionFlipFromRight forView:myview cache:YES];
Here is a sample:
[UIView beginAnimations:nil context:NULL]; {
[UIView setAnimationCurve:UIViewAnimationCurveEaseInOut];
[UIView setAnimationDuration:1.0];
[UIView setAnimationDelegate:self];
if (movingViewIn) {
// after the animation is over, call afterAnimationProceedWithGame
// to start the game
[UIView setAnimationDidStopSelector:@selector(afterAnimationProceedWithGame)];
// [UIView setAnimationRepeatCount:5.0]; // don't forget you can repeat an animation
// [UIView setAnimationDelay:0.50];
// [UIView setAnimationRepeatAutoreverses:YES];
gameView.alpha = 1.0;
topGameView.alpha = 1.0;
viewrect1.origin.y = selfrect.size.height - (viewrect1.size.height);
viewrect2.origin.y = -20;
topGameView.alpha = 1.0;
}
else {
// call putBackStatusBar after animation to restore the state after this animation
[UIView setAnimationDidStopSelector:@selector(putBackStatusBar)];
gameView.alpha = 0.0;
topGameView.alpha = 0.0;
}
[gameView setFrame:viewrect1];
[topGameView setFrame:viewrect2];
} [UIView commitAnimations];
As you can see, you can play with alpha, frames, and even sizes of a view. Play around. You may be surprised with its capabilities.
if you're using reactive forms then you can use the following way. consider the following example.
`<p class="mr-3"> Require Shipping:
<input type="radio" class="ml-2" value="true" name="requiresShipping"
id="requiresShipping" formControlName="requiresShipping">
Yes
<input type="radio" class="ml-2" value="false" name="requiresShipping"
id="requiresShipping" formControlName="requiresShipping">
No
</p>`
`
export class ClassName implements OnInit {
public yourForm: FormGroup
constructor(
private fromBuilder: FormBuilder
) {
this.yourForm= this.fromBuilder.group({
requiresShipping: this.fromBuilder.control('true'),
})
}
}
`
now you will get the default selected radio button.
BFree's answer worked for me. I needed to post the stream right to the browser. Which I'd imagine is a common alternative. I added the following to BFree's Main() code to do this:
//StreamReader reader = new StreamReader(stream);
//Console.WriteLine(reader.ReadToEnd());
string fileName = "fileName.csv";
HttpContext.Current.Response.ContentType = "application/vnd.openxmlformats-officedocument.spreadsheetml.sheet";
HttpContext.Current.Response.AddHeader("content-disposition", string.Format("attachment;filename={0}", fileName));
stream.Position = 0;
stream.WriteTo(HttpContext.Current.Response.OutputStream);
you can also do this in aggregation by using project at 3.4
{$project: {"tags.words": 0} }
In Fedora 25, it turned out to be an SE Linux issue, and the notification gave this solution which worked for me.
setsebool -P httpd_read_user_content 1
Just wanted to clarify that the snippet from accepted answer gives the nearest midnight in the past:
var d = new Date();
d.setHours(0,0,0,0); // last midnight
If you want to get the nearest midnight in future, use the following code:
var d = new Date();
d.setHours(24,0,0,0); // next midnight
Your mock is raising the exception just fine, but the error.resp.status
value is missing. Rather than use return_value
, just tell Mock
that status
is an attribute:
barMock.side_effect = HttpError(mock.Mock(status=404), 'not found')
Additional keyword arguments to Mock()
are set as attributes on the resulting object.
I put your foo
and bar
definitions in a my_tests
module, added in the HttpError
class so I could use it too, and your test then can be ran to success:
>>> from my_tests import foo, HttpError
>>> import mock
>>> with mock.patch('my_tests.bar') as barMock:
... barMock.side_effect = HttpError(mock.Mock(status=404), 'not found')
... result = my_test.foo()
...
404 -
>>> result is None
True
You can even see the print '404 - %s' % error.message
line run, but I think you wanted to use error.content
there instead; that's the attribute HttpError()
sets from the second argument, at any rate.
I was importing also some projects from VS2010 to VS 2012. I had the same errors. The errors disappeared when I set back Properties > Config. Properties > General > Platform Toolset to v100 (VS2010). That might not be the correct approach, however.
The test command ([
here) has a "not" logical operator which is the exclamation point (similar to many other languages). Try this:
if [ ! -f /tmp/foo.txt ]; then
echo "File not found!"
fi
If you copy a folder from local then it will copy folder with all its sub folders to HDFS.
For copying a folder from local to hdfs, you can use
hadoop fs -put localpath
or
hadoop fs -copyFromLocal localpath
or
hadoop fs -put localpath hdfspath
or
hadoop fs -copyFromLocal localpath hdfspath
Note:
If you are not specified hdfs path then folder copy will be copy to hdfs with the same name of that folder.
To copy from hdfs to local
hadoop fs -get hdfspath localpath
The following should work and not require any permissions in the manifest (basically override shouldOverrideUrlLoading and handle links separately from tel, mailto, etc.):
mWebView = (WebView) findViewById(R.id.web_view);
WebSettings webSettings = mWebView.getSettings();
webSettings.setJavaScriptEnabled(true);
mWebView.setWebViewClient(new WebViewClient(){
@Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
if( url.startsWith("http:") || url.startsWith("https:") ) {
return false;
}
// Otherwise allow the OS to handle things like tel, mailto, etc.
Intent intent = new Intent(Intent.ACTION_VIEW, Uri.parse(url));
startActivity( intent );
return true;
}
});
mWebView.loadUrl(url);
Also, note that in the above snippet I am enabling JavaScript, which you will also most likely want, but if for some reason you don't, just remove those 2 lines.
An alternative approach is to use numpy.resize()
as in:
In [37]: shp = (50,100,25)
In [38]: arr = np.random.random_sample(shp)
In [45]: resized_arr = np.resize(arr, (np.prod(shp[:2]), shp[-1]))
In [46]: resized_arr.shape
Out[46]: (5000, 25)
# sanity check with other solutions
In [47]: resized = np.reshape(arr, (-1, shp[-1]))
In [48]: np.allclose(resized_arr, resized)
Out[48]: True
Query in Parado's answer is correct, if you want to use MySql too instead GETDATE() you must use (because you've tagged this question with Sql server and Mysql):
select * from tab
where DateCol between adddate(now(),-7) and now()
A quick way to do it in sql server 2012 is as follows:
SELECT FORMAT(GETDATE() , 'dd/MM/yyyy HH:mm:ss')
You are trying to index into a scalar (non-iterable) value:
[y[1] for y in y_test]
# ^ this is the problem
When you call [y for y in test]
you are iterating over the values already, so you get a single value in y
.
Your code is the same as trying to do the following:
y_test = [1, 2, 3]
y = y_test[0] # y = 1
print(y[0]) # this line will fail
I'm not sure what you're trying to get into your results array, but you need to get rid of [y[1] for y in y_test]
.
If you want to append each y in y_test to results, you'll need to expand your list comprehension out further to something like this:
[results.append(..., y) for y in y_test]
Or just use a for loop:
for y in y_test:
results.append(..., y)
I have resolved this problem to add some change like git add -A and git commit again.
I have just rewritten the code to the following:
$dbhost = "localhost";
$dbname = "pdo";
$dbusername = "root";
$dbpassword = "845625";
$link = new PDO("mysql:host=$dbhost;dbname=$dbname", $dbusername, $dbpassword);
$link->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
$statement = $link->prepare("INSERT INTO testtable(name, lastname, age)
VALUES(?,?,?)");
$statement->execute(array("Bob","Desaunois",18));
And it seems to work now. BUT. if I on purpose cause an error to occur, it does not say there is any. The code works, but still; should I encounter more errors, I will not know why.
Here's a less broken datetime
-based solution to convert from datetime object to posix timestamp:
future = datetime.datetime.utcnow() + datetime.timedelta(minutes=5)
return (future - datetime.datetime(1970, 1, 1)).total_seconds()
See more details at Converting datetime.date to UTC timestamp in Python.
The manual for GNU Make gives a clear definition for all
in its list of standard targets.
If the author of the Makefile is following that convention then the target all
should:
make
should do the same as make all
.To achieve 1 all
is typically defined as a .PHONY
target that depends on the executable(s) that form the entire program:
.PHONY : all
all : executable
To achieve 2 all
should either be the first target defined in the make file or be assigned as the default goal:
.DEFAULT_GOAL := all
(Mar 2017) The accepted answer is not the best solution. It relies on manual translation using Apps Script, and the code may not be resilient, requiring maintenance. If your legacy system autogenerates CSV files, it's best they go into another folder for temporary processing (importing [uploading to Google Drive & converting] to Google Sheets files).
My thought is to let the Drive API do all the heavy-lifting. The Google Drive API team released v3 at the end of 2015, and in that release, insert()
changed names to create()
so as to better reflect the file operation. There's also no more convert flag -- you just specify MIMEtypes... imagine that!
The documentation has also been improved: there's now a special guide devoted to uploads (simple, multipart, and resumable) that comes with sample code in Java, Python, PHP, C#/.NET, Ruby, JavaScript/Node.js, and iOS/Obj-C that imports CSV files into Google Sheets format as desired.
Below is one alternate Python solution for short files ("simple upload") where you don't need the apiclient.http.MediaFileUpload
class. This snippet assumes your auth code works where your service endpoint is DRIVE
with a minimum auth scope of https://www.googleapis.com/auth/drive.file
.
# filenames & MIMEtypes
DST_FILENAME = 'inventory'
SRC_FILENAME = DST_FILENAME + '.csv'
SHT_MIMETYPE = 'application/vnd.google-apps.spreadsheet'
CSV_MIMETYPE = 'text/csv'
# Import CSV file to Google Drive as a Google Sheets file
METADATA = {'name': DST_FILENAME, 'mimeType': SHT_MIMETYPE}
rsp = DRIVE.files().create(body=METADATA, media_body=SRC_FILENAME).execute()
if rsp:
print('Imported %r to %r (as %s)' % (SRC_FILENAME, DST_FILENAME, rsp['mimeType']))
Better yet, rather than uploading to My Drive
, you'd upload to one (or more) specific folder(s), meaning you'd add the parent folder ID(s) to METADATA
. (Also see the code sample on this page.) Finally, there's no native .gsheet "file" -- that file just has a link to the online Sheet, so what's above is what you want to do.
If not using Python, you can use the snippet above as pseudocode to port to your system language. Regardless, there's much less code to maintain because there's no CSV parsing. The only thing remaining is to blow away the CSV file temp folder your legacy system wrote to.
Easy as this:
string[] folders = System.IO.Directory.GetDirectories(@"C:\My Sample Path\","*", System.IO.SearchOption.AllDirectories);
The best way I've been able to do this is with using the new css object-fit
(1) property and the padding-bottom

You need a wrapper element around the image. You can use whatever you want, but I like using the new HTML picture

Using the following code in your .htaccess file automatically redirects visitors to the HTTPS version of your site:
RewriteEngine On
RewriteCond %{HTTPS} off
RewriteRule ^(.*)$ https://%{HTTP_HOST}%{REQUEST_URI} [L,R=301]
Various forms depending on type of List, for Array List:
val myList = mutableListOf<Kolory>()
// or more specifically use the helper for a specific list type
val myList = arrayListOf<Kolory>()
For LinkedList:
val myList = linkedListOf<Kolory>()
// same as
val myList: MutableList<Kolory> = linkedListOf()
For other list types, will be assumed Mutable if you construct them directly:
val myList = ArrayList<Kolory>()
// or
val myList = LinkedList<Kolory>()
This holds true for anything implementing the List
interface (i.e. other collections libraries).
No need to repeat the type on the left side if the list is already Mutable. Or only if you want to treat them as read-only, for example:
val myList: List<Kolory> = ArrayList()
extern "C"
is a linkage specification which is used to call C functions in the Cpp source files. We can call C functions, write Variables, & include headers. Function is declared in extern entity & it is defined outside. Syntax is
Type 1:
extern "language" function-prototype
Type 2:
extern "language"
{
function-prototype
};
eg:
#include<iostream>
using namespace std;
extern "C"
{
#include<stdio.h> // Include C Header
int n; // Declare a Variable
void func(int,int); // Declare a function (function prototype)
}
int main()
{
func(int a, int b); // Calling function . . .
return 0;
}
// Function definition . . .
void func(int m, int n)
{
//
//
}
This should work in almost all browsers:
var xhr=new XMLHttpRequest();
xhr.open("GET","https://12Me21.github.io/test.txt");
xhr.onload=function(){
console.log(xhr.responseText);
}
xhr.send();
Additionally, there's the new Fetch
API:
fetch("https://12Me21.github.io/test.txt")
.then( response => response.text() )
.then( text => console.log(text) )
componentWillUnmount
setState
,This is what your are looking for:
from numpy import array
a=array([1,2,3])
b=array([4,5,6])
a + 1j*b
->array([ 1.+4.j, 2.+5.j, 3.+6.j])
there is no timeout, by default.

The two syntaxes are not equivalent and it can lead to unexpected errors. Here is a simple example showing the differences. If you have a model:
from django.db import models
class Test(models.Model):
added = models.DateTimeField(auto_now_add=True)
And you create a first object:
foo = Test.objects.create(pk=1)
Then you try to create an object with the same primary key:
foo_duplicate = Test.objects.create(pk=1)
# returns the error:
# django.db.utils.IntegrityError: (1062, "Duplicate entry '1' for key 'PRIMARY'")
foo_duplicate = Test(pk=1).save()
# returns the error:
# django.db.utils.IntegrityError: (1048, "Column 'added' cannot be null")

The ssh daemon (sshd), which runs server-side, closes the connection from the server-side if the client goes silent (i.e., does not send information). To prevent connection loss, instruct the ssh client to send a sign-of-life signal to the server once in a while.
The configuration for this is in the file $HOME/.ssh/config
, create the file if it does not exist (the config file must not be world-readable, so run chmod 600 ~/.ssh/config
after creating the file). To send the signal every e.g. four minutes (240 seconds) to the remote host, put the following in that configuration file:
Host remotehost
HostName remotehost.com
ServerAliveInterval 240
To enable sending a keep-alive signal for all hosts, place the following contents in the configuration file:
Host *
ServerAliveInterval 240
I am using XAMPP on Win 7 and 8.1 too...it start normally.
Did you try to check the services on Start > RUN > services.msc
Find the service: Apache 2.x. (right click) choose Properties. At form "Startup type" choose "Automatically" and Start the service on.
you should reset the PC and check out again.
Do the same with mySQL.
If you can not solve the problem, use XAMPP Panel to start it manually.

Regarding the freezing issue, we found this occurred when processing CSV files with at least one extremely long line.

However, it appears to have been fixed in PyCharm 4.5.4, so if you experience this, try updating your PyCharm.

Just to add that you don't really need to create new IDs, something like the following will work.
In the layout:
<ListView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:id="@android:id/list"/>
<TextView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:id="@android:id/empty"
android:text="Empty"/>
Then in the activity:
ListView listView = (ListView) findViewById(android.R.id.list);
listView.setEmptyView(findViewById(android.R.id.empty));
Others here have suggested a couple multi-record syntaxes. Expounding upon that, I suggest you insert into a temp table first, and insert your main table from there.
The reason for this is loading the data from a query can take longer, and you may end up locking the table or pages longer than is necessary, which slows down other queries running against that table.
-- Make a temp table with the needed columns
select top 0 *
into #temp
from MyTable (nolock)
-- load data into it at your leisure (nobody else is waiting for this table or these pages)
insert #temp (ID, Name)
values (123, 'Timmy'),
(124, 'Jonny'),
(125, 'Sally')
-- Now that all the data is in SQL, copy it over to the real table. This runs much faster in most cases.
insert MyTable (ID, Name)
select ID, Name
from #temp
-- cleanup
drop table #temp
Also, your IDs should probably be identity(1,1) and you probably shouldn't be inserting them, in the vast majority of circumstances. Let SQL decide that stuff for you.
I had this issue too, and all I did to get rid of it was to delete the existing Server (in my case Tomcat) configurations from project and eclipse workspace.
This issue in my case occurred when I played around with my Maven settings and finally screwed them too. But eventually I fixed my Maven issues to realize the tomcat server wont start and failed to load the application context(s) of various apps involved in my project. That's when I decided to drop the existing server configurations.
I then added the Apache Server once again all over afresh. Then followed with my project specific setting/additions. And it finally worked like a charm.
This type of thing should be done server-side, so as to limit the amount of resources used on the client for such trivial tasks. That being said, if you were to do it on the front-end, I would encourage you to consider using something like underscore.js to keep the code clean and concise:
var values = ["Red", "Green"],
colors = document.getElementById("colors");
_.each(colors.options, function (option) {
option.selected = ~_.indexOf(values, option.text);
});
If you're using jQuery, it could be even more terse:
var values = ["Red", "Green"];
$("#colors option").prop("selected", function () {
return ~$.inArray(this.text, values);
});
If you were to do this without a tool like underscore.js or jQuery, you would have a bit more to write, and may find it to be a bit more complicated:
var color, i, j,
values = ["Red", "Green"],
options = document.getElementById("colors").options;
for ( i = 0; i < values.length; i++ ) {
for ( j = 0, color = values[i]; j < options.length; j++ ) {
options[j].selected = options[j].selected || color === options[j].text;
}
}
WAMP server generally provide addond for different php/mysql versions. However you mentioned you have downloaded latest wamp server. As of now, latest Wamp server v2.5 provide PHP version 5.5.12
So you need to upgrade it manually as follow:
Although not asked, I'd recommend to vagrant/puppet or docker for local development. Check puphpet.com for details. It has slight learning curve but it will give you much better control of different versions of every tool.
Reload sdk maybe the problem is solved

@William You can use NewRow method of the datatable to get a blank datarow and with the schema as that of the datatable. You can populate this datarow and then add the row to the datatable using .Rows.Add(DataRow)
OR .Rows.InsertAt(DataRow, Position)
. The following is a stub code which you can modify as per your convenience.
//Creating dummy datatable for testing
DataTable dt = new DataTable();
DataColumn dc = new DataColumn("col1", typeof(String));
dt.Columns.Add(dc);
dc = new DataColumn("col2", typeof(String));
dt.Columns.Add(dc);
dc = new DataColumn("col3", typeof(String));
dt.Columns.Add(dc);
dc = new DataColumn("col4", typeof(String));
dt.Columns.Add(dc);
DataRow dr = dt.NewRow();
dr[0] = "coldata1";
dr[1] = "coldata2";
dr[2] = "coldata3";
dr[3] = "coldata4";
dt.Rows.Add(dr);//this will add the row at the end of the datatable
//OR
int yourPosition = 0;
dt.Rows.InsertAt(dr, yourPosition);
Based on Mark's answer above (and Geo's comment), I created a two liner version to remove all ASCII exception cases from a string. Provided for people searching for this answer (as I did).
using System.Text;
// Create encoder with a replacing encoder fallback
var encoder = ASCIIEncoding.GetEncoding("us-ascii",
new EncoderReplacementFallback(string.Empty),
new DecoderExceptionFallback());
string cleanString = encoder.GetString(encoder.GetBytes(dirtyString));
If it's only a tuple of tuples, something like rows=[map(int, row) for row in rows]
will do the trick. (There's a list comprehension and a call to map(f, lst), which is equal to [f(a) for a in lst], in there.)
Eval is not what you want to do, in case there's something like __import__("os").unlink("importantsystemfile")
in your database for some reason.
Always validate your input (if with nothing else, the exception int() will raise if you have bad input).
Just set the display:none on the elements that you want to hide:
<table>
<tr><th>Test Table</th><tr>
<tr style="display:none"><td>1. 123456789</td><tr>
<tr><td>2. 123456789</td><tr>
<tr><td>3. 123456789</td><tr>
</table>
Definition:
public static string GetLast(string source, int last)

return last >= source.Length ? source : source.Substring(source.Length - last);
}
Usage:
GetLast("string of", 2);
Result:

In case anyone is interested (even if the question does not ask for this version), in C# 2 would be: (I have edited the answer, following some suggestions)
myList.Sort(CLASS_FOR_COMPARER);
List<string> fiveElements = myList.GetRange(0, 5);
You can also generate in a range [min, max] with something like
float float_rand( float min, float max )
{
float scale = rand() / (float) RAND_MAX; /* [0, 1.0] */
return min + scale * ( max - min ); /* [min, max] */
}
String.split() will do most of what you want. You may then need to loop over the words to pull out any punctuation.
For example:
String s = "This is a sample sentence.";
String[] words = s.split("\\s+");
for (int i = 0; i < words.length; i++) {
// You may want to check for a non-word character before blindly
// performing a replacement
// It may also be necessary to adjust the character class
words[i] = words[i].replaceAll("[^\\w]", "");

Note that React's create-react-app
tool-chain supports the null-coalescing since version 3.3.0 (released 5.12.2019). From the release notes:
Optional Chaining and Nullish Coalescing Operators
We now support the optional chaining and nullish coalescing operators!
// Optional chaining a?.(); // undefined if `a` is null/undefined b?.c; // undefined if `b` is null/undefined // Nullish coalescing undefined ?? 'some other default'; // result: 'some other default' null ?? 'some other default'; // result: 'some other default' '' ?? 'some other default'; // result: '' 0 ?? 300; // result: 0 false ?? true; // result: false
This said, in case you use create-react-app
3.3.0+ you can start using the null-coalesce operator already today in your React apps.
The JVM doesn't know anything about off-heap memory. Ehcache implements an on-disk cache as well as an in-memory cache.
I have also found some more error subcodes, in case of OAuth exception. Copied from the facebook bugtracker, without any garantee (maybe contain deprecated, wrong and discontinued ones):

Other users commenting that the Content-Type
is plain/text
when encoding. You have to set the Content-Type
first w.Header().Set
, then the HTTP response code w.WriteHeader
.
If you call w.WriteHeader
first then call w.Header().Set
after you will get plain/text
.
An example handler might look like this;
func SomeHandler(w http.ResponseWriter, r *http.Request) {
data := SomeStruct{}
w.Header().Set("Content-Type", "application/json")
w.WriteHeader(http.StatusCreated)
json.NewEncoder(w).Encode(data)
}
I quickly wrote this C# console app to do this:

Simply pass a directory as a parameter and it will do its best to tell you the net framework for each dll and exe in there
In Bootstrap 4, the correct way to border your elements is to name them as follows in the class list of your elements:
For a slight rounding effect on all corners; class="rounded"
For a slight rounding on the left; class="rounded-left"
For a slight rounding on the top; class="rounded-top"
For a slight rounding on the right; class="rounded-right"
For a slight rounding on the bottom; class="rounded-bottom"
For a circle rounding, i.e. your element is made circular; class="rounded-circle"
And to remove rounding effects; class="rounded-0"
To use Bootstrap 4 css files, you can simply use the CDN, and use the following link in the of your HTML file:
<script src="https://stackpath.bootstrapcdn.com/bootstrap/4.1.3/js/bootstrap.min.js" integrity="sha384-ChfqqxuZUCnJSK3+MXmPNIyE6ZbWh2IMqE241rYiqJxyMiZ6OW/JmZQ5stwEULTy" crossorigin="anonymous"></script>
This will provided you with the basics of Bootstrap 4. However if you would like to use the majority of Bootstrap 4 components, including tooltips, popovers, and dropdowns, then you are best to use the following code instead:
<script src="https://code.jquery.com/jquery-3.3.1.slim.min.js" integrity="sha384-q8i/X+965DzO0rT7abK41JStQIAqVgRVzpbzo5smXKp4YfRvH+8abtTE1Pi6jizo" crossorigin="anonymous"></script>
<script src="https://cdnjs.cloudflare.com/ajax/libs/popper.js/1.14.3/umd/popper.min.js" integrity="sha384-ZMP7rVo3mIykV+2+9J3UJ46jBk0WLaUAdn689aCwoqbBJiSnjAK/l8WvCWPIPm49" crossorigin="anonymous"></script>

Alternatively, you can install Bootstrap using NPM, or Bower, and link to the files there.
*Note that the bottom tag of the three is the same as the first tag in the first link path.
A full working example, could be :
<img src="path/to/my/image/image.jpg" width="150" height="150" class="rounded-circle mx-auto">
In the above example, the image is centered by using the Bootstrap auto margin on left and right.
This worked for me but only after forcing the specific verbs to be handled by the default handler.
<system.web>
...
<httpHandlers>
...
<add path="*" verb="OPTIONS" type="System.Web.DefaultHttpHandler" validate="true"/>
<add path="*" verb="TRACE" type="System.Web.DefaultHttpHandler" validate="true"/>
<add path="*" verb="HEAD" type="System.Web.DefaultHttpHandler" validate="true"/>
You still use the same configuration as you have above, but also force the verbs to be handled with the default handler and validated. Source: http://forums.asp.net/t/1311323.aspx
An easy way to test is just to deny GET and see if your site loads.
Try writing all the errors to a file.
error_reporting(-1); // reports all errors
ini_set("display_errors", "1"); // shows all errors
ini_set("log_errors", 1);
ini_set("error_log", "/tmp/php-error.log");
Something like that.
Basically, ajax request as well as synchronous request sends your document cookies automatically. So, you need to set your cookie to document, not to request. However, your request is cross-domain, and things became more complicated. Basing on this answer, additionally to set document cookie, you should allow its sending to cross-domain environment:
type: "GET",
url: "http://example.com",
cache: false,
// NO setCookies option available, set cookie to document
//setCookies: "lkfh89asdhjahska7al446dfg5kgfbfgdhfdbfgcvbcbc dfskljvdfhpl",
crossDomain: true,
dataType: 'json',
xhrFields: {
withCredentials: true
},
success: function (data) {
alert(data);
});
I assume you want the PDF to display in the browser, rather than forcing a download. If that is the case, try setting the Content-Disposition
header with a value of inline
.
Also remember that this will also be affected by browser settings - some browsers may be configured to always download PDF files or open them in a different application (e.g. Adobe Reader)
You can get any type of extra data from intent, no matter if it's an object or string or any type of data.
Bundle extra = getIntent().getExtras();
if (extra != null){
String str1 = (String) extra.get("obj"); // get a object
String str2 = extra.getString("string"); //get a string
}
and the Shortest solution is:
Boolean isGranted = getIntent().getBooleanExtra("tag", false);
Try setting the timeout value in your web service proxy class:
WebReference.ProxyClass myProxy = new WebReference.ProxyClass();
myProxy.Timeout = 100000; //in milliseconds, e.g. 100 seconds
Its better to build ObservableCollection and take advantage of it
public ObservableCollection<string> list = new ObservableCollection<string>();
list.Add("a");
list.Add("b");
list.Add("c");
this.cbx.ItemsSource = list;
cbx is comobobox name

You should define source code encoding, add this to the top of your script:
# -*- coding: utf-8 -*-
The reason why it works differently in console and in the IDE is, likely, because of different default encodings set. You can check it by running:
import sys
print sys.getdefaultencoding()
Also see:
$('#menucontainer').click(function(e){
e.stopPropagation();
});
$(document).on('click', function(e){
// code
});
Check where your clang
is located:
which clang
It should be somewhere under /usr/bin/clang
.
In my case from old times it was coming from Miniconda that was put artificially on the command line PATH. Fix that so that clang comes from Xcode and that should bring you forward.
Props can change when a component's parent renders the component again with different properties. I think this is mostly an optimization so that no new component needs to be instantiated.

Rule of three in C++ is a fundamental principle of the design and the development of three requirements that if there is clear definition in one of the following member function, then the programmer should define the other two members functions together. Namely the following three member functions are indispensable: destructor, copy constructor, copy assignment operator.
Copy constructor in C++ is a special constructor. It is used to build a new object, which is the new object equivalent to a copy of an existing object.
Copy assignment operator is a special assignment operator that is usually used to specify an existing object to others of the same type of object.
There are quick examples:
// default constructor
My_Class a;
// copy constructor
My_Class b(a);
// copy constructor
My_Class c = a;
// copy assignment operator
b = a;
In visual studio, use the "Add Web Reference" feature and then enter in the URL of your web service.
By adding a reference to the DLL, you not referencing it as a web service, but simply as an assembly.
When you add a web reference it create a proxy class in your project that has the same or similar methods/arguments as your web service. That proxy class communicates with your web service via SOAP but hides all of the communications protocol stuff so you don't have to worry about it.
In case you are looking for datepicker in spanish (datepicker en español)

My 2¢! Really, part of the reason I'm throwing this up here, despite the long list of answers, is to provide a little more all in one
type solution and get some feed back in the future on how to expand it to include more real types
.
With the following solution, as aforementioned, I combined a couple of solutions found here, as well as incorporate a fix for returning a value of jQuery on jQuery defined object if available. I also append the method to the native Object prototype. I know that is often taboo, as it could interfere with other such extensions, but I leave that to user beware
. If you don't like this way of doing it, simply copy the base function anywhere you like and replace all variables of this
with an argument parameter to pass in (such as arguments[0]).
;(function() { // Object.realType
function realType(toLower) {
var r = typeof this;
try {
if (window.hasOwnProperty('jQuery') && this.constructor && this.constructor == jQuery) r = 'jQuery';
else r = this.constructor && this.constructor.name ? this.constructor.name : Object.prototype.toString.call(this).slice(8, -1);
}
catch(e) { if (this['toString']) r = this.toString().slice(8, -1); }
return !toLower ? r : r.toLowerCase();
}
Object['defineProperty'] && !Object.prototype.hasOwnProperty('realType')
? Object.defineProperty(Object.prototype, 'realType', { value: realType }) : Object.prototype['realType'] = realType;
})();
Then simply use with ease, like so:
obj.realType() // would return 'Object'
obj.realType(true) // would return 'object'
Note: There is 1 argument passable. If is bool of
true
, then the return will always be in lowercase.
More Examples:
true.realType(); // "Boolean"
var a = 4; a.realType(); // "Number"
$('div:first').realType(); // "jQuery"
document.createElement('div').realType() // "HTMLDivElement"
If you have anything to add that maybe helpful, such as defining when an object was created with another library (Moo, Proto, Yui, Dojo, etc...) please feel free to comment or edit this and keep it going to be more accurate and precise. OR roll on over to the GitHub I made for it and let me know. You'll also find a quick link to a cdn min file there.
Even if it is really discouraged to use merge cells in Excel (use Center Across Selection
for instance if needed), the cell that "contains" the value is the one on the top left (at least, that's a way to express it).
Hence, you can get the value of merged cells in range B4:B11
in several ways:
Range("B4").Value
Range("B4:B11").Cells(1).Value
Range("B4:B11").Cells(1,1).Value
You can also note that all the other cells have no value in them. While debugging, you can see that the value is empty
.
Also note that Range("B4:B11").Value
won't work (raises an execution error number 13 if you try to Debug.Print
it) because it returns an array.
I solved it by using the default password for cacerts keystore : 'changeit'

You can use below to query to find row count.
Using pg_class:
SELECT reltuples::bigint AS EstimatedCount

,n_live_tup AS EstimatedCount
FROM pg_stat_user_tables
ORDER BY n_live_tup DESC;

By using pg_restore command you can restore postgres database
First open terminal type
sudo su postgres
Create new database
createdb [database name] -O [owner]
createdb test_db [-O openerp]
pg_restore -d [Database Name] [path of dump file]
pg_restore -d test_db /home/sagar/Download/sample_dbump
Wait for completion of database restoring.
Remember that dump file should have read, write, execute access, so for that you can apply chmod command
In file /etc/ssh/sshd_config
# Change to no to disable tunnelled clear text passwords
#PasswordAuthentication no
Uncomment the second line, and, if needed, change yes to no.
Then run
service ssh restart
Errors like that are usually sent to the "standard error" stream, which you can pipe to a file or just make disappear on most commands:
grep pattern * -R -n 2>/dev/null

In Webdriver, you should use driver.switchTo().defaultContent();
to get out of a frame.
You need to get out of all the frames first, then switch into outer frame again.
// between step 4 and step 5
// remove selenium.selectFrame("relative=up");
driver.switchTo().defaultContent(); // you are now outside both frames
driver.switchTo().frame("cq-cf-frame");
// now continue step 6
driver.findElement(By.xpath("//button[text()='OK']")).click();
Yes, using the indexOf() method on the string class. See the API documentation for this method
I have solved this problem You just need to Create file in Android Folder
Go android folder
Create file local.properties
then just add this code in local.properties file:-
If you are using MacBook then sdk.dir=/Users/USERNAME/Library/android/sdk
if you are using Windows then sdk.dir=C:\Users\USERNAME\AppData\Local\Android\sdk
if you are using Linux then sdk.dir = /home/USERNAME/Android/sdk
if you want to know what is your system USERNAME then just use command for Mac whoami
and then just rerun command react-native run-android
Thanks :)
How do you iterate std::set?
int main(int argc,char *argv[])
{
std::set<int> mset;
mset.insert(1);
mset.insert(2);
mset.insert(3);
for ( auto it = mset.begin(); it != mset.end(); it++ )
std::cout << *it;
}
The tab character is \t
. Notice the use of "
instead of '
.
$chunk = "abc\tdef\tghi";
If the string is enclosed in double-quotes ("), PHP will interpret more escape sequences for special characters:
...
\t horizontal tab (HT or 0x09 (9) in ASCII)
Also, let me recommend the fputcsv() function which is for the purpose of writing CSV files.
I have wasted 3 days
ultimately solved a graph question
used for
finding shortest distance
using BFS
Want to share the experience.
When the (undirected for me) graph has
fixed distance (1, 6, etc.) for edges
#1
We can use BFS to find shortest path simply by traversing it
then, if required, multiply with fixed distance (1, 6, etc.)
#2
As noted above
with BFS
the very 1st time an adjacent node is reached, it is shortest path
#3
It does not matter what queue you use
deque/queue(c++) or
your own queue implementation (in c language)
A circular queue is unnecessary
#4
Number of elements required for queue is N+1 at most, which I used
(dint check if N works)
here, N is V, number of vertices.
#5
Wikipedia BFS will work, and is sufficient.
https://en.wikipedia.org/wiki/Breadth-first_search#Pseudocode
I have lost 3 days trying all above alternatives, verifying & re-verifying again and again above
they are not the issue.
(Try to spend time looking for other issues, if you dint find any issues with above 5).
More explanation from the comment below:
A
/ \
B C
/\ /\
D E F G
Assume above is your graph
graph goes downwards
For A, the adjacents are B & C
For B, the adjacents are D & E
For C, the adjacents are F & G
say, start node is A
when you reach A, to, B & C the shortest distance to B & C from A is 1
when you reach D or E, thru B, the shortest distance to A & D is 2 (A->B->D)
similarly, A->E is 2 (A->B->E)
also, A->F & A->G is 2
So, now instead of 1 distance between nodes, if it is 6, then just multiply the answer by 6
example,
if distance between each is 1, then A->E is 2 (A->B->E = 1+1)
if distance between each is 6, then A->E is 12 (A->B->E = 6+6)
yes, bfs may take any path
but we are calculating for all paths
if you have to go from A to Z, then we travel all paths from A to an intermediate I, and since there will be many paths we discard all but shortest path till I, then continue with shortest path ahead to next node J
again if there are multiple paths from I to J, we only take shortest one
example,
assume,
A -> I we have distance 5
(STEP) assume, I -> J we have multiple paths, of distances 7 & 8, since 7 is shortest
we take A -> J as 5 (A->I shortest) + 8 (shortest now) = 13
so A->J is now 13
we repeat now above (STEP) for J -> K and so on, till we get to Z
Read this part, 2 or 3 times, and draw on paper, you will surely get what i am saying, best of luck
Besides the window resize functions mentioned it is important to understand that the resize events fire a lot if used without a deboucing the events.
Paul Irish has an excellent function that debounces the resize calls a great deal. Very recommended to use. Works cross-browser. Tested it in IE8 the other day and all was fine.
http://www.paulirish.com/2009/throttled-smartresize-jquery-event-handler/
Make sure to check out the demo to see the difference.
Here is the function for completeness.
(function($,sr){
// debouncing function from John Hann
// http://unscriptable.com/index.php/2009/03/20/debouncing-javascript-methods/
var debounce = function (func, threshold, execAsap) {
var timeout;
return function debounced () {
var obj = this, args = arguments;
function delayed () {
if (!execAsap)
func.apply(obj, args);
timeout = null;
};
if (timeout)
clearTimeout(timeout);
else if (execAsap)
func.apply(obj, args);
timeout = setTimeout(delayed, threshold || 100);
};
}
// smartresize
jQuery.fn[sr] = function(fn){ return fn ? this.bind('resize', debounce(fn)) : this.trigger(sr); };
})(jQuery,'smartresize');
// usage:
$(window).smartresize(function(){
// code that takes it easy...
});
you just add the path of .pdb to work directory of VS!
You can use
str1.compareTo(str2);
If str1 is lexicographically less than str2, a negative number
will be returned, 0
if equal or a positive number
if str1 is greater.
E.g.,
"a".compareTo("b"); // returns a negative number, here -1
"a".compareTo("a"); // returns 0
"b".compareTo("a"); // returns a positive number, here 1
"b".compareTo(null); // throws java.lang.NullPointerException

Check if you're using an Ad Hoc Distribution provisioning profile and not an App Store Distribution provisioning profile instead, I was getting this error because of that.
You can set the environment variable through process global variable as follows:
process.env['NODE_ENV'] = 'production';
Works in all platforms.
I think that it's around 2GB. While the answer by Pete Kirkham is very interesting and probably holds truth, I have allocated upwards of 3GB without error, however it did not use 3GB in practice. That might explain why you were able to allocate 2.5 GB on 2GB RAM with no swap space. In practice, it wasn't using 2.5GB.
Either use instanceof
or method Class.isAssignableFrom(Class<?> cls)
.
King King's answer is of course right. Also Tim Schmelter's comment is also good suggestion in your case.
But if you want really remove last comma in a string, you should find the index of last comma and remove like;
string s = "1,5,12,34,12345";
int index = s.LastIndexOf(',');
Console.WriteLine(s.Remove(index, 1));
Output will be;
1,5,12,3412345
Here a demonstration
.
It is too unlikely you want this way but I want to point it. And remember, String.Remove
method doesn't remove any character in original string, it returns new string.
The Simple Difference is: console.log() methods automatically append new line character. It means if we are looping through and printing the result, each result get printed in new line.
process.stdout.write() methods don't append new line character. useful for printing patterns.
"\n"
is not working everywhere!For example in email, it adds the exact "\n" into the text instead of a new line if you use it in the custom keyboard like: textDocumentProxy.insertText("\n")
There are another newLine characters available but I can't just simply paste them here (Because they make a new lines).
using this extension:
extension CharacterSet {
var allCharacters: [Character] {
var result: [Character] = []
for plane: UInt8 in 0...16 where self.hasMember(inPlane: plane) {
for unicode in UInt32(plane) << 16 ..< UInt32(plane + 1) << 16 {
if let uniChar = UnicodeScalar(unicode), self.contains(uniChar) {
result.append(Character(uniChar))
}
}
}
return result
}
}
you can access all characters in any CharacterSet
. There is a character set called newlines
. Use one of them to fulfill your requirements:
let newlines = CharacterSet.newlines.allCharacters
for newLine in newlines {
print("Hello World \(newLine) This is a new line")
}
Then store the one you tested and worked everywhere and use it anywhere. Note that you can't relay on the index of the character set. It may change.
But most of the times "\n"
just works as expected.
I will post answer that helped me:
go to url:
chrome://settings/clearBrowserData
it should invoke popup and then..
cached images and files
.from beginning
// Safari uses pre-calculated pixels, so use this feature to detect Safari
var canva = document.createElement('canvas');
var ctx = canva.getContext("2d");
var img = ctx.getImageData(0, 0, 1, 1);
var pix = img.data; // byte array, rgba
var isSafari = (pix[3] != 0); // alpha in Safari is not zero
After i tried all methods and they did not work for me.
I get the solution by using another PortDuff.MODE.
imgEstadoBillete.setColorFilter(context.getResources().getColor(R.color.green),PorterDuff.Mode.SRC_IN);
Had the same problem for few days. Found a solution at last. The PHP server returned some unseen characters which you could not see in the LOG or in System.out.
So the solution was that i tried to substring my json String one by one and when i came to substring(3) the error went away.
BTW. i used UTF-8 encoding on both sides.
PHP side: header('Content-type=application/json; charset=utf-8');
JAVA side: BufferedReader reader = new BufferedReader(new InputStreamReader(is, "utf-8"), 8);
So try the solution one by one 1,2,3,4...! Hope it helps you guys!
try {
jObj = new JSONObject(json.substring(3));
} catch (JSONException e) {
Log.e("JSON Parser", "Error parsing data [" + e.getMessage()+"] "+json);
}
For Bootstrap 3
The workflow I had to deal with was loading content with a url context that could change. So by default setup your modal with javascript or the href for the default context you want to show :
$('#myModal').modal({
show: false,
remote: 'some/context'
});
Destroying the modal wouldn't work for me because I wasn't loading from the same remote, thus I had to :
$(".some-action-class").on('click', function () {
$('#myModal').removeData('bs.modal');
$('#myModal').modal({remote: 'some/new/context?p=' + $(this).attr('buttonAttr') });
$('#myModal').modal('show');
});
This of course was easily refactored into a js library and gives you a lot of flexibility with loading modals
I hope this saves someone 15 minutes of tinkering.
Remember that a single =
is always an assignment in C or C++.
Your test should be if ( match == 0 && k == M )
you made a typo on the k == M
test.
If you really mean k=M
(i.e. a side-effecting assignment inside a test) you should for readability reasons code if (match == 0 && (k=m) != 0)
but most coding rules advise not writing that.
BTW, your mistake suggests to ask for all warnings (e.g. -Wall
option to g++
), and to upgrade to recent compilers. The next GCC 4.8 will give you:
% g++-trunk -Wall -c ederman.cc
ederman.cc: In function ‘void foo()’:
ederman.cc:9:30: error: lvalue required as left operand of assignment
if ( match == 0 && k = M )
^
and Clang 3.1 also tells you ederman.cc:9:30: error: expression is not assignable
So use recent versions of free compilers and enable all the warnings when using them.
The following will work in MVC 4
@Html.HiddenFor(x => x.CRN, new { @Value = "1" });
@Value property is case sensitive. You need a capital 'V' on @Value.
Here is my model
public int CRN { get; set; }
Here is what is output in html when you look in the browser
<input value="1" data-val="true" data-val-number="The field CRN must be a number." data-val-required="The CRN field is required." id="CRN" name="CRN" type="hidden" value="1"/>
Here is my method
[HttpPost]
public ActionResult MyMethod(MyViewModel viewModel)
{
int crn = viewModel.CRN;
}
If BranchA has not been pushed to a remote then you can reorder the commits using rebase
and then simply merge
. It's preferable to use merge
over rebase
when possible because it doesn't create duplicate commits.
git checkout BranchA
git rebase -i HEAD~113
... reorder the commits so the 10 you want are first ...
git checkout BranchB
git merge [the 10th commit]
I understand you have a scenario with ErrorDocument already defined within your apache conf or .htaccess and want to make those pages appear when manually sending a 4xx status code via php.
Unfortunately this is not possible with common methods because php sends header directly to user's browser (not to Apache web server) whereas ErrorDocument is a display handler for http status generated from Apache.
The method, as indicated by their technical considerations page, is correct - so you're definitely not doing anything wrong. However, this bug report on Google Code indicate that there is a problem with the fonts Google produced for this, specifically the IE version. This only seems to affect only some fonts, but it's a real bummmer.
The answers on the thread indicate that the problem lies with the files Google's serving up, so there's nothing you can do about it. The author suggest getting the fonts from alternative locations, like FontSquirrel, and serving it locally instead, in which case you might also be interested in sites like the League of Movable Type.
N.B. As of Oct 2010 the issue is reported as fixed and closed on the Google Code bug report.
No offense but to check for performance of sql I executed some of the above mentioned solutiona pgsql.
Let me share you Statistics of top 3 solution approaches that I come across.
1) Took : 1.58 MS Avg
2) Took : 2.87 MS Avg
3) Took : 3.95 MS Avg
Now try this :
SELECT * FROM table WHERE DATE_TRUNC('day', date ) >= Start Date AND DATE_TRUNC('day', date ) <= End Date
Now this solution took : 1.61 Avg.
And best solution is 1st that suggested by marco-mariani
If you're using Express, then you can use its compress method as part of the configuration:
var express = require('express');
var app = express.createServer();
app.use(express.compress());
And you can find more on compress here: http://expressjs.com/api.html#compress
And if you're not using Express... Why not, man?! :)
NOTE: (thanks to @ankitjaininfo) This middleware should be one of the first you "use" to ensure all responses are compressed. Ensure that this is above your routes and static handler (eg. how I have it above).
NOTE: (thanks to @ciro-costa) Since express 4.0, the express.compress
middleware is deprecated. It was inherited from connect 3.0 and express no longer includes connect 3.0. Check Express Compression for getting the middleware.
Right click on the project --> New --> Other --> Standard Deployment Descriptor(web.xml)
then press Next it will create WEB-INF
folder with a web.xml
file inside.
That's it done.
For me, this is the best autofit and autoresize for table and its columns (use css !important ... only if you can't without)
.myclass table {
table-layout: auto !important;
}
.myclass th, .myclass td, .myclass thead th, .myclass tbody td, .myclass tfoot td, .myclass tfoot th {
width: auto !important;
}
Don't specify css width for table or for table columns. If table content is larger it will go over screen size to.
You don't need any jQuery specific code to handle this. Just use a RegExp to replace them:
$("#a").className = $("#a").className.replace(/\bbg.*?\b/g, '');
You can modify this to support any prefix but the faster method is above as the RegExp will be compiled only once:
function removeClassByPrefix(el, prefix) {
var regx = new RegExp('\\b' + prefix + '.*?\\b', 'g');
el.className = el.className.replace(regx, '');
return el;
}
Typescript: following should work,
export const getTimeBetweenDates = ({
until,
format
}: {
until: number;
format: 'seconds' | 'minutes' | 'hours' | 'days';
}): number => {
const date = new Date();
const remainingTime = new Date(until * 1000);
const getFrom = moment([date.getUTCFullYear(), date.getUTCMonth(), date.getUTCDate()]);
const getUntil = moment([remainingTime.getUTCFullYear(), remainingTime.getUTCMonth(), remainingTime.getUTCDate()]);
const diff = getUntil.diff(getFrom, format);
return !isNaN(diff) ? diff : null;
};
You can use the typeid operator:
#include <typeinfo>
...
cout << typeid(variable).name() << endl;
After adding the ICO file to your apps resources, you can use references it using My.Resources.YourIconNameWithoutExtension
For example if I had a file called Logo-square.ico added to my apps resources, I can set it to an icon with:
NotifyIcon1.Icon = My.Resources.Logo_square
This is a sample method i created to validate email addresses, if the string parameter passed is a valid email address , it returns true, else false is returned.
private boolean validateEmailAddress(String emailAddress){
String expression="^[\\w\\-]([\\.\\w])+[\\w]+@([\\w\\-]+\\.)+[A-Z]{2,4}$";
CharSequence inputStr = emailAddress;
Pattern pattern = Pattern.compile(expression,Pattern.CASE_INSENSITIVE);
Matcher matcher = pattern.matcher(inputStr);
return matcher.matches();
}
DateTime.Now.Tostring();
. You can supply parameters to To string function in a lot of ways like given in this link http://www.geekzilla.co.uk/View00FF7904-B510-468C-A2C8-F859AA20581F.htm
This will be a lot useful. If you reside somewhere else than the regular format (MM/dd/yyyy)
use always MM not mm, mm gives minutes and MM gives month.
After my previous answer disaster, I'm going to try something else.
List<Model> usrList =
(list.Where(n => n.application == "applicationame").ToList());
usrList.ForEach(n => n.users.RemoveAll(n => n.surname != "surname"));
Also you can try to use
@JsonSerialize(include=JsonSerialize.Inclusion.NON_NULL)
if you are dealing with jackson with version below 2+ (1.9.5) i tested it, you can easily use this annotation above the class. Not for specified for the attributes, just for class decleration.
In JPQL the same is actually true in the spec. The JPA spec does not allow an alias to be given to a fetch join. The issue is that you can easily shoot yourself in the foot with this by restricting the context of the join fetch. It is safer to join twice.
This is normally more an issue with ToMany than ToOnes. For example,
Select e from Employee e
join fetch e.phones p
where p.areaCode = '613'
This will incorrectly return all Employees that contain numbers in the '613' area code but will left out phone numbers of other areas in the returned list. This means that an employee that had a phone in the 613 and 416 area codes will loose the 416 phone number, so the object will be corrupted.
Granted, if you know what you are doing, the extra join is not desirable, some JPA providers may allow aliasing the join fetch, and may allow casting the Criteria Fetch to a Join.
This only work below IE 11 version.
var ie_version = parseInt(window.navigator.userAgent.substring(window.navigator.userAgent.indexOf("MSIE ") + 5, window.navigator.userAgent.indexOf(".", window.navigator.userAgent.indexOf("MSIE "))));
console.log("version number",ie_version);
<?php if ($foo) { ?>
<div class="mydiv">Condition is true</div>
<?php } else { ?>
<div class="myotherdiv">Condition is false</div>
<?php } ?>
Flask requires you to associate a single 'view function' with an 'endpoint'. You are calling Main.as_view('main')
twice which creates two different functions (exactly the same functionality but different in memory signature). Short story, you should simply do
main_view_func = Main.as_view('main')
app.add_url_rule('/',
view_func=main_view_func,
methods=["GET"])
app.add_url_rule('/<page>/',
view_func=main_view_func,
methods=["GET"])
None of the suggested solutions worked for me.
I had run tomcat restart
before completing the deployment which messed up my web app.
EC2 ran tomcat automatically and tomcat was stuck trying to connect to a database connection which was not configured properly.
I just needed to remove my customized context in server.xml, restart tomcat and add the context back in.
A typical best practice is not using long/int/short directly. Instead, according to specification of compilers and OS, wrap them into a header file to ensure they hold exactly the amount of bits that you want. Then use int8/int16/int32 instead of long/int/short. For example, on 32bit Linux, you could define a header like this
typedef char int8;
typedef short int16;
typedef int int32;
typedef unsigned int uint32;
Many answers here describe dangerous methods where they instantiate a file input stream but do not get a reference to the input stream in order to close the stream later. This results in dangling input streams and memory leaks. The correct way of loading the properties should be similar to following:
Properties prop = new Properties();
try(InputStream fis = new FileInputStream("myProp.properties")) {
prop.load(fis);
}
catch(Exception e) {
System.out.println("Unable to find the specified properties file");
e.printStackTrace();
return;
}
Note the instantiating of the file input stream in try-with-resources
block. Since a FileInputStream
is autocloseable, it will be automatically closed after the try-with-resources
block is exited. If you want to use a simple try
block, you must explicitly close it using fis.close();
in the finally
block.
If you ever end up with the same problem with Scala and SBT:
Go to Project Structure. The shortcut is (CTRL + ALT + SHIFT + S)
On the far left list, choose Project Settings > Modules
On the module list right of that, select the module of your project name (without the build) and choose the sources tab
In middle, expand the folder that the root of your project for me that's /home/<username>/IdeaProjects/<projectName>
Look at the Content Root section on the right side, the red paths are directories that you haven't made. You'll want to put the properties file in a Resources directory. So I created src/main/resources
and put log4j.properties in it. I believe you can also modify the Content Root to put it wherever you want (I didn't do this).
I ran my code with a SBT configuration and it found my log4j.properties file.
Download http://download.cnet.com/Free-Desktop-Timer/3000-2350_4-75415517.html
Then add a button or something on the form and inside its event, just open this app ie:
{
Process.Start(@"C:\Program Files (x86)\Free Desktop Timer\DesktopTimer");
}
With the background-size property in those browsers which support this very new feature of CSS.
Quoted from this post:
The question is about how to make CTRL+SHIFT+U work in Visual Studio Code. Here is how to do it. (Version 1.8.1 or above). You can also choose a different key combination.
File-> Preferences -> Keyboard Shortcuts.
An editor will appear with
keybindings.json
file. Place the following JSON in there and save.[ { "key": "ctrl+shift+u", "command": "editor.action.transformToUppercase", "when": "editorTextFocus" }, { "key": "ctrl+shift+l", "command": "editor.action.transformToLowercase", "when": "editorTextFocus" } ]
Now CTRL+SHIFT+U will capitalise selected text, even if multi line. In the same way, CTRL+SHIFT+L will make selected text lowercase.
These commands are built into VS Code, and no extensions are required to make them work.
To create a view controller:
UIViewController * vc = [[UIViewController alloc] init];
To call a view controller (must be called from within another viewcontroller):
[self presentViewController:vc animated:YES completion:nil];
For one, use nil rather than null.
Loading a view controller from the storyboard:
NSString * storyboardName = @"MainStoryboard";
UIStoryboard *storyboard = [UIStoryboard storyboardWithName:storyboardName bundle: nil];
UIViewController * vc = [storyboard instantiateViewControllerWithIdentifier:@"IDENTIFIER_OF_YOUR_VIEWCONTROLLER"];
[self presentViewController:vc animated:YES completion:nil];
Identifier
of your view controller is either equal to the class name of your view controller, or a Storyboard ID that you can assign in the identity inspector of your storyboard.
server.servlet.context-path=/api
would be the solution I guess. I had the same issue and this got me solved. I used server.context-path. However, that seemed to be deprecated and I found that server.servlet.context-path
solves the issue now. Another workaround I found was adding a base tag to my front end (H5) pages. I hope this helps someone out there.
Cheers
In case you dont need the message body in html, turn it off:
message.IsBodyHtml = false;
then use e.g:
message.Body = "First line" + Environment.NewLine +
"Second line";
but if you need to have it in html for some reason, use the html-tag:
message.Body = "First line <br /> Second line";
Before you can commit and push, you need to init a working repository tree for a submodule. I am using tortoise and do following things:
First check if there exist .git file (not a directory)
If there was .git file, there surly was .git directory which tracks local tree. You still need to a branch (you can create one) or switch to master (which sometimes does not work). Best to do is - git fetch - git pull. Do not omit fetch.
Now your commits and pulls will be synchronized with your origin/master
For my application, i have done this way
<ListView
android:id="@+id/staff_jobassigned_listview"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:divider="@null"
android:dividerHeight="10dp">
</ListView>
just set the divider to null
and providing height to the divider did for me.
Example :
android:divider="@null"
or
android:divider="@android:color/transparent"
and this is result
The same problem arrised for me when I installed Kaliko CMS Nuget Package. When I removed it, it started working fine again. So, your problem could be because of a recently installed Nuget Package. Uninstall it and your solution will work just fine.
Solution with extra property in Activity\Fragment, but without any hypothetical hardcoded heights (like 100 etc) . Just add OnGlobalLayoutListener to your root view and save its initial height before keyboard will be shown:
var firstLoad = true
var contentFullWeight = 0
override fun onViewCreated(layoutView: View, savedInstanceState: Bundle?) {
super.onViewCreated(layoutView, savedInstanceState)
view?.viewTreeObserver?.addOnGlobalLayoutListener(ViewTreeObserver.OnGlobalLayoutListener {
if(firstLoad){
contentFullWeight = view?.height!!
firstLoad = false
}
if (view?.height!! < contentFullWeight) {
Log.d("TEZT_KEYBOARD", ">> KBD OPENED")
} else {
Log.d("TEZT_KEYBOARD", ">> KBD closed")
}
})
}
I'm not crazy about the other answers here; they're too vague and abstract for me. I think more in stories. Here's my attempt at a better answer.
Let's say it's 1985 and you write a short BASIC program on an Apple II:
] 10 PRINT "HELLO WORLD!"
] 20 GOTO 10
So far, your program is just source code. It's not running, and we would say there is no "runtime" involved with it.
But now I run it:
] RUN
How is it actually running? How does it know how to send the string parameter from PRINT
to the physical screen? I certainly didn't provide any system information in my code, and PRINT
itself doesn't know anything about my system.
Instead, RUN
is actually a program itself -- its code tells it how to parse my code, how to execute it, and how to send any relevant requests to the computer's operating system. The RUN
program provides the "runtime" environment that acts as a layer between the operating system and my source code. The operating system itself acts as part of this "runtime", but we usually don't mean to include it when we talk about a "runtime" like the RUN
program.
In some languages, your source code must be compiled before it can be run. Some languages compile your code into machine language -- it can be run by your operating system directly. This compiled code is often called "binary" (even though every other kind of file is also in binary :).
In this case, there is still a minimal "runtime" involved -- but that runtime is provided by the operating system itself. The compile step means that many statements that would cause your program to crash are detected before the code is ever run.
C is one such language; when you run a C program, it's totally able to send illegal requests to the operating system (like, "give me control of all of the memory on the computer, and erase it all"). If an illegal request is hit, usually the OS will just kill your program and not tell you why, and dump the contents of that program's memory at the time it was killed to a .dump
file that's pretty hard to make sense of. But sometimes your code has a command that is a very bad idea, but the OS doesn't consider it illegal, like "erase a random bit of memory this program is using"; that can cause super weird problems that are hard to get to the bottom of.
Other languages compile your code into a language that the operating system can't read directly, but a specific runtime program can read your compiled code. This compiled code is often called "bytecode".
The more elaborate this runtime program is, the more extra stuff it can do on the side that your code did not include (even in the libraries you use) -- for instance, the Java runtime environment ("JRE") can keep track of memory assignments that are no longer needed, and tell the operating system it's safe to reuse that memory for something else, and it can catch situations where your code would try to send an illegal request to the operating system, and instead exit with a readable error.
All of this overhead makes them slower than compiled binary languages, but it makes the runtime powerful and flexible; in some cases, it can even pull in other code after it starts running, without having to start over. The compile step means that many statements that would cause your program to crash are detected before the code is ever run; and the powerful runtime can keep your code from doing stupid things (e.g., you can't "erase a random bit of memory this program is using").
Still other languages don't precompile your code at all; the runtime does all of the work of reading your code line by line, interpreting it and executing it. This makes them even slower than "bytecode" languages, but also even more flexible; in some cases, you can even fiddle with your source code as it runs! Though it also means that you can have a totally illegal statement in your code, and it could sit there in your production code without drawing attention, until one day it is run and causes a crash.
These are generally called "scripting" languages; they include Javascript, Python, Perl, and PHP. Some of these provide cases where you can choose to compile the code to improve its speed (e.g., Javascript's WebAssembly project, and Python's trans-compilation to C code). So Javascript can allow users on a website to see the exact code that is running, since their browser is providing the runtime.
This flexibility also allows for innovations in runtime environments, like node.js, which is both a code library and a runtime environment that can run your Javascript code as a server, which involves behaving very differently than if you tried to run the same code on a browser.
Using ripgrep's replace option, it is possible to change the output to a capture group:
rg --only-matching --replace '$1' '(\d+) rofl'
--only-matching
or -o
outputs only the part that matches instead of the whole line.--replace '$1'
or -r
replaces the output by the first capture group.new Guid(string)
You could also look at using a TypeConverter
.
I use svnX (http://code.google.com/p/svnx/downloads/list), it is free and usable, but not as user friendly as tortoise. It shows you the review before commit with diff for every file... but sometimes I still had to go to command line to fix some things
fun rotateArrow(view: View): Boolean {
return if (view.rotation == 0F) {
view.animate().setDuration(200).rotation(180F)
true
} else {
view.animate().setDuration(200).rotation(0F)
false
}
}
In my case right after installing the MAMP accessing mysql from the terminal was giving the same socket error. At the end all it wanted was a restart and it's working.
The term overloading refers to having multiple versions of something with the same name, usually methods with different parameter lists
public int DoSomething(int objectId) { ... }
public int DoSomething(string objectName) { ... }
So these functions might do the same thing but you have the option to call it with an ID, or a name. Has nothing to do with inheritance, abstract classes, etc.
Overriding usually refers to polymorphism, as you described in your question
I kind of like this method which I think covers all the bases:
const matches = str.match(/aeiou/gi];
return matches ? matches.length : 0;
I'll throw my hat into the ring just to talk about securing passwords in general on Android. On Android, the device binary should be considered compromised - this is the same for any end application which is in direct user control. Conceptually, a hacker could use the necessary access to the binary to decompile it and root out your encrypted passwords and etc.
As such there's two suggestions I'd like to throw out there if security is a major concern for you:
1) Don't store the actual password. Store a granted access token and use the access token and the signature of the phone to authenticate the session server-side. The benefit to this is that you can make the token have a limited duration, you're not compromising the original password and you have a good signature that you can use to correlate to traffic later (to for instance check for intrusion attempts and invalidate the token rendering it useless).
2) Utilize 2 factor authentication. This may be more annoying and intrusive but for some compliance situations unavoidable.

I would echo what Wyzard wrote but add that:
URLEncoder
should not be usedI wrote a blog post a while back about this subject: Java: safe character handling and URL building
I tried to fix likely the same issue which caused by twitter bootstrap .modal-open
class applied to body
. The solution html {overflow-y: scroll}
doesn't help. One possible solution I found is to add {width: 100%; width: 100vw}
to the html
element.
This was not working for me in Firefox.
We added a conditional based on whether the code places the overflow at the html level. See Animate scrollTop not working in firefox.
var $header = $("#header #menu-wrap-left"),
$clone = $header.before($header.clone().addClass("clone"));
$(window).on("scroll", function() {
var fromTop = Array();
fromTop["body"] = $("body").scrollTop();
fromTop["html"] = $("body,html").scrollTop();
if (fromTop["body"])
$('body').toggleClass("down", (fromTop["body"] > 650));
if (fromTop["html"])
$('body,html').toggleClass("down", (fromTop["html"] > 650));
});
Sometimes it might be something pretty simple like missing your resource file in test-classses folder due to some cleanups.
If using the following HTML:
<button id="submit-button"></button>
Style can be applied through JS using the style object available on an HTMLElement.
To set height and width to 200px of the above example button, this would be the JS:
var myButton = document.getElementById('submit-button');
myButton.style.height = '200px';
myButton.style.width= '200px';
I believe with this method, you are not directly writing CSS (inline or external), but using JavaScript to programmatically alter CSS Declarations.
Set is just an interface. In order to retain order, you have to use a specific implementation of that interface and the sub-interface SortedSet, for example TreeSet or LinkedHashSet. You can wrap your Set this way:
Set myOrderedSet = new LinkedHashSet(mySet);
I think you can try add parameter axis=1

print pd.concat([df.iloc[0,:], df.iloc[-1,:]], axis=1)

b a d
print pd.concat([df.iloc[0,:], df.iloc[-1,:]], axis=1).T

System.out.println((int)chr); //output:83
Now i want to convert Ascii value into Charecter/Symbol.
int n=(int)chr;
System.out.println((char)n);//output:S
Use .Date of a DateTime object will ignore the time portion.
Here is code:
DateTime dateA = DateTime.Now;
DateTime dateB = DateTime.Now.AddHours(1).AddMinutes(10).AddSeconds(14);
Console.WriteLine("Date A: {0}",dateA.ToString("o"));
Console.WriteLine("Date B: {0}", dateB.ToString("o"));
Console.WriteLine(String.Format("Comparing objects A==B? {0}", dateA.Equals(dateB)));
Console.WriteLine(String.Format("Comparing ONLY Date property A==B? {0}", dateA.Date.Equals(dateB.Date)));
Console.ReadLine();
Output:
>Date A: 2014-09-04T07:53:14.6404013+02:00
>Date B: 2014-09-04T09:03:28.6414014+02:00
>Comparing objects A==B? False
>Comparing ONLY Date property A==B? True

I found that I could access the checkbox directly using Worksheets("SheetName").CB_Checkboxname.value
directly without relating to additional objects.
Time traveler here. If you generally want to have multiple statements within a lambda, you can pass other lambdas as arguments to that lambda.
(lambda x, f: list((y[1] for y in f(x))))(lst, lambda x: (sorted(y) for y in x))
You can't actually have multiple statements, but you can simulate that by passing lambdas to lambdas.
Edit: The time traveler returns! You can also abuse the behavior of boolean expressions (keeping in mind short-circuiting rules and truthiness) to chain operations. Using the ternary operator gives you even more power. Again, you can't have multiple statements, but you can of course have many function calls. This example does some arbitrary junk with a bunch of data, but, it shows that you can do some funny stuff. The print statements are examples of functions which return None
(as does the .sort()
method) but they also help show what the lambda
is doing.
>>> (lambda x: print(x) or x+1)(10)
10
11
>>> f = (lambda x: x[::2] if print(x) or x.sort() else print(enumerate(x[::-1]) if print(x) else filter(lambda (i, y): print((i, y)) or (i % 3 and y % 2), enumerate(x[::-1]))))
>>> from random import shuffle
>>> l = list(range(100))
>>> shuffle(l)
>>> f(l)

So you're using screen to keep the experiments running in the background, or what? If so, why not just start it in the background?
./experiment &
And if you're asking how to get notification the job i done, how about stringing the experiment together with a mail command?
./experiment && echo "the deed is done" | mail youruser@yourlocalworkstation -s "job on server $HOSTNAME is done"
Which version of JUnit is this? I've only ever seen delta, not epsilon - but that's a side issue!
From the JUnit javadoc:
delta - the maximum delta between expected and actual for which both numbers are still considered equal.
It's probably overkill, but I typically use a really small number, e.g.
private static final double DELTA = 1e-15;
@Test
public void testDelta(){
assertEquals(123.456, 123.456, DELTA);
}
If you're using hamcrest assertions, you can just use the standard equalTo()
with two doubles (it doesn't use a delta). However if you want a delta, you can just use closeTo()
(see javadoc), e.g.
private static final double DELTA = 1e-15;
@Test
public void testDelta(){
assertThat(123.456, equalTo(123.456));
assertThat(123.456, closeTo(123.456, DELTA));
}
FYI the upcoming JUnit 5 will also make delta optional when calling assertEquals()
with two doubles. The implementation (if you're interested) is:
private static boolean doublesAreEqual(double value1, double value2) {
return Double.doubleToLongBits(value1) == Double.doubleToLongBits(value2);
}
Fortran (designed for scientific computing) has a built-in power operator, and as far as I know Fortran compilers will commonly optimize raising to integer powers in a similar fashion to what you describe. C/C++ unfortunately don't have a power operator, only the library function pow()
. This doesn't prevent smart compilers from treating pow
specially and computing it in a faster way for special cases, but it seems they do it less commonly ...
Some years ago I was trying to make it more convenient to calculate integer powers in an optimal way, and came up with the following. It's C++, not C though, and still depends on the compiler being somewhat smart about how to optimize/inline things. Anyway, hope you might find it useful in practice:
template<unsigned N> struct power_impl;
template<unsigned N> struct power_impl {
template<typename T>
static T calc(const T &x) {
if (N%2 == 0)
return power_impl<N/2>::calc(x*x);
else if (N%3 == 0)
return power_impl<N/3>::calc(x*x*x);
return power_impl<N-1>::calc(x)*x;
}
};
template<> struct power_impl<0> {
template<typename T>
static T calc(const T &) { return 1; }
};
template<unsigned N, typename T>
inline T power(const T &x) {
return power_impl<N>::calc(x);
}
Clarification for the curious: this does not find the optimal way to compute powers, but since finding the optimal solution is an NP-complete problem and this is only worth doing for small powers anyway (as opposed to using pow
), there's no reason to fuss with the detail.
Then just use it as power<6>(a)
.
This makes it easy to type powers (no need to spell out 6 a
s with parens), and lets you have this kind of optimization without -ffast-math
in case you have something precision dependent such as compensated summation (an example where the order of operations is essential).
You can probably also forget that this is C++ and just use it in the C program (if it compiles with a C++ compiler).
Hope this can be useful.
EDIT:
This is what I get from my compiler:
For a*a*a*a*a*a

For Python 3.x, use input()
. For Python 2.x, use raw_input()
. Don't forget you can add a prompt string in your input()
call to create one less print statement. input("GUESS THAT NUMBER!")
.
Except for the answer by @Ed G, all of the answers require knowing which bound is the lower and which is the upper one.
Here's a (rather non-obvious) way of doing it when you don't know which bound is which.
/// <summary>
/// Method to test if a value is "between" two other values, when the relative magnitude of
/// the two other values is not known, i.e., number1 may be larger or smaller than number2.
/// The range is considered to be inclusive of the lower value and exclusive of the upper
/// value, irrespective of which parameter (number1 or number2) is the lower or upper value.
/// This implies that if number1 equals number2 then the result is always false.
///
/// This was extracted from a larger function that tests if a point is in a polygon:
/// http://www.ecse.rpi.edu/Homepages/wrf/Research/Short_Notes/pnpoly.html
/// </summary>
/// <param name="testValue">value to be tested for being "between" the other two numbers</param>
/// <param name="number1">one end of the range</param>
/// <param name="number2">the other end of the range</param>
/// <returns>true if testValue >= lower of the two numbers and less than upper of the two numbers,
/// false otherwise, incl. if number1 == number2</returns>
private static bool IsInRange(T testValue, T number1, T number2)
{
return (testValue <= number1) != (testValue <= number2);
}
Note: This is NOT a generic method; it is pseudo code. The T in the above method should be replaced by a proper type, "int" or "float" or whatever. (There are ways of making this generic, but they're sufficiently messy that it's not worth while for a one-line method, at least not in most situations.)

Use c_str() to convert the std::string to const char *.
cout << "String is : " << text.c_str() << endl ;
File.isFile()
is false
if the file / directory does not exist, so you can't use it to test whether you're trying to create a directory. But that's not the first issue here.
The issue is that the intermediate directories don't exist. You want to call f.mkdirs()
first.
I was having this same issue. I found out if you go to the Task in Task Scheduler that is running the powershell.exe script, you can click "Run whether user is logged on or not" and that will never show the powershell window when the task runs.
You can do that with list comprehension too:
A=[[x*100, x][x % 2 != 0] for x in range(1,11)]
print A
In JSFiddle, when you set the wrapping to "onLoad" or "onDomready", the functions you define are only defined inside that block, and cannot be accessed by outside event handlers.
Easiest fix is to change:
function something(...)
To:
window.something = function(...)
I also ran into this all of a sudden, after it had previously worked, and it was because I was inside a virtualenv, and wheel

1. Change your DOCTYPE to something less strict. Don't use XHTML; it's silly. Just use the HTML 5 doctype and you're good:
<!doctype html>

spring boot allows us to write different profiles to write for different environments, for example we can have separate properties files for production, qa and local environments
application-local.properties file with configurations according to my local machine is
spring.profiles.active=local
spring.data.mongodb.host=localhost
spring.data.mongodb.port=27017
spring.data.mongodb.database=users
spring.data.mongodb.username=humble_freak
spring.data.mongodb.password=freakone
spring.rabbitmq.host=localhost
spring.rabbitmq.username=guest
spring.rabbitmq.password=guest
spring.rabbitmq.port=5672
rabbitmq.publish=true
Similarly, we can write application-prod.properties and application-qa.properties as many properties files as we want
then write some scripts to start the application for different environments, for e.g.
mvn spring-boot:run -Drun.profiles=local
mvn spring-boot:run -Drun.profiles=qa
mvn spring-boot:run -Drun.profiles=prod
Your CRON should look like this:
*/5 * * * *
CronWTF is really usefull when you need to test out your CRON settings.
Might be a good idea to pipe the output into a log file so you can see if your script is throwing any errors too - since you wont see them in your terminal.
Also try using a shebang at the top of your PHP file, so the system knows where to find PHP. Such as:
#!/usr/bin/php
that way you can call the whole thing like this
*/5 * * * * php /path/to/script.php > /path/to/logfile.log
I found this method on http://www.mrexcel.com/
This computes the number of non-blank cells in column A of worksheet named "Data"
With Worksheets("Data")
Ndt =Application.Range("A:A").Cells.SpecialCells(xlCellTypeConstants).Count
debug.print Ndt
End With
The result is printed to the immediate window. You need to subtract 1 (or more) if column A has a header line (or lines) you do not wish to count.
The iframe always keeps the parent page, you should use this to detect in which page you are in the iframe:
Html code:
<iframe id="iframe" frameborder="0" scrolling="no" onload="resizeIframe(this)" width="100%" src="www.google.com"></iframe>
Js:
function resizeIframe(obj) {
alert(obj.contentWindow.location.pathname);
}
This is the syntax to import class
<%@ page import="package.class" %>
Same problem/answer here, quoted below
I'm assuming you mean that you want to run your own private video calls, not simply link to Skype calls or similar. You really have 2 options here: host it yourself, or use a hosted solution and integrate it into your product.
Self-Hosted ----------------- This is messy. This can all be accomplished with PHP, but that is probably not the most advisable solution, as it is not the best tool for the job on all sides. Flash is much more efficient at a/v capture and transport on the user end. You can try to do this without flash, but you will have headaches. HTML5 may make your life easier, but if you're shooting for maximum compatibility, flash is the simplest way to go for creating the client. Then, as far as the actual server side that will relay the audio/video, you could write a chat server in php, but you're better off using an open source project, like janenz00's mention of red5, that's already built and interfacing with it through your client (if it doesn't already have one). Or you could homebrew a flash client as mentioned before and hook it up to a flash streaming server on both sides...either way it gets complicated fast, and is beyond my expertise to help you with at all.
Hosted Service ----------------- All in, my recommendation, unless you want to administer a ridiculous setup of many complex servers and failure points is to use a hosted service like UserPlane or similar and offload all the processing and technical work to people who are good at that, and then worry about interfacing with their api and getting their client well integrated into your site. You will be a happier developer if you do.
Indeed, the 9th byte indicates the check state of the button, but the answers above don't take into account the checkbox which enables manual configuration. This check state value is also present in this ninth byte. The real answer should thus be:
Byte value
00001001 = Manual proxy is checked
00000101 = Use automatic configuration script is checked
00000011 = Automatically detect settings is checked
When multiple checkboxes are checked, the value of the 9th byte is the result of the bitwise OR operation on the values for which the checkbox is checked.

I use Remote login with vnc-ltsp-config with GNOME Desktop Environment on CentOS 5.9. From experimenting today, I managed to get cut and paste working for the session and the login prompt (because I'm lazy and would rather copy and paste difficult passwords).
I created a file vncconfig.desktop in the /etc/xdg/autostart directory which enabled cut and paste during the session after login. The vncconfig process is run as the logged in user.
[Desktop Entry]
Name=No name
Encoding=UTF-8
Version=1.0
Exec=vncconfig -nowin
X-GNOME-Autostart-enabled=true
Added vncconfig -nowin & to the bottom of the file /etc/gdm/Init/Desktop which enabled cut and paste in the session during login but terminates after login. The vncconfig process is run as root.
Adding vncconfig -nowin & to the bottom of the file /etc/gdm/PostLogin/Desktop also enabled cut and paste during the session after login. The vncconfig process is run as root however.
Check out the COPY command of Postgres:
Put the entire script into a template string, with {SERVERNAME} placeholders. Then edit the string using:
SET @SQL_SCRIPT = REPLACE(@TEMPLATE, '{SERVERNAME}', @DBNAME)
and then run it with
EXECUTE (@SQL_SCRIPT)
It's hard to believe that, in the course of three years, nobody noticed that my code doesn't work!
You can't EXEC
multiple batches. GO
is a batch separator, not a T-SQL statement. It's necessary to build three separate strings, and then to EXEC
each one after substitution.
I suppose one could do something "clever" by breaking the single template string into multiple rows by splitting on GO
; I've done that in ADO.NET code.
And where did I get the word "SERVERNAME" from?
Here's some code that I just tested (and which works):
DECLARE @DBNAME VARCHAR(255)
SET @DBNAME = 'TestDB'
DECLARE @CREATE_TEMPLATE VARCHAR(MAX)
DECLARE @COMPAT_TEMPLATE VARCHAR(MAX)
DECLARE @RECOVERY_TEMPLATE VARCHAR(MAX)
SET @CREATE_TEMPLATE = 'CREATE DATABASE {DBNAME}'
SET @COMPAT_TEMPLATE='ALTER DATABASE {DBNAME} SET COMPATIBILITY_LEVEL = 90'
SET @RECOVERY_TEMPLATE='ALTER DATABASE {DBNAME} SET RECOVERY SIMPLE'
DECLARE @SQL_SCRIPT VARCHAR(MAX)
SET @SQL_SCRIPT = REPLACE(@CREATE_TEMPLATE, '{DBNAME}', @DBNAME)
EXECUTE (@SQL_SCRIPT)
SET @SQL_SCRIPT = REPLACE(@COMPAT_TEMPLATE, '{DBNAME}', @DBNAME)
EXECUTE (@SQL_SCRIPT)
SET @SQL_SCRIPT = REPLACE(@RECOVERY_TEMPLATE, '{DBNAME}', @DBNAME)
EXECUTE (@SQL_SCRIPT)
Use this query to create the new table with the values from existing table
CREATE TABLE New_Table_name AS SELECT * FROM Existing_table_Name;
Now you can get all the values from existing table into newly created table.
