You can use this aproach:
Response.Clear();
StringBuilder sb = new StringBuilder();
sb.Append("<html>");
sb.AppendFormat(@"<body onload='document.forms[""form""].submit()'>");
sb.AppendFormat("<form name='form' action='{0}' method='post'>",postbackUrl);
sb.AppendFormat("<input type='hidden' name='id' value='{0}'>", id);
// Other params go here
sb.Append("</form>");
sb.Append("</body>");
sb.Append("</html>");
Response.Write(sb.ToString());
Response.End();
As result right after client will get all html from server the event onload take place that triggers form submit and post all data to defined postbackUrl.
Contruct your url via click event handler:
string strUrl = "/some/url/path" + myvar;
Then:
ScriptManager.RegisterStartupScript(Page, Page.GetType(), "popup", "window.open('" + strUrl + "','_blank')", true);
Once you send any content at all to the client, the HTTP headers have already been sent. A Response.Redirect()
call works by sending special information in the headers that make the browser ask for a different URL.
Since the headers were already sent, asp.net can't do what you want (modify the headers)
You can get around this by a) either doing the Redirect before you do anything else, or b) try using Response.Buffer = true
before you do anything else, to make sure that no output is sent to the client until the whole page is done executing.
you can get the current url with window.location.href
but I think you will need the jQuery query plugin to manipulate the query string: http://plugins.jquery.com/project/query-object
To work around this problem, use one of the following methods:
For Response.End, call the HttpContext.Current.ApplicationInstance.CompleteRequest() method instead of Response.End to bypass the code execution to the Application_EndRequest event.
For Response.Redirect, use an overload, Response.Redirect(String url, bool endResponse) that passes false for the endResponse parameter to suppress the internal call to Response.End. For example:
Response.Redirect ("nextpage.aspx", false);
If you use this workaround, the code that follows Response.Redirect is executed.For Server.Transfer, use the Server.Execute method instead.
If you use the Response.End, Response.Redirect, or Server.Transfer method, a ThreadAbortException exception occurs. You can use a try-catch statement to catch this exception.
The Response.End method ends the page execution and shifts the execution to the Application_EndRequest event in the application's event pipeline. The line of code that follows Response.End is not executed.
This problem occurs in the Response.Redirect and Server.Transfer methods because both methods call Response.End internally.
This behavior is by design.

Wouldn't you be better off with
<asp:HyperLink ID="HyperLink1" runat="server"
NavigateUrl="CMS_1.aspx"
Target="_blank">
Click here
</asp:HyperLink>
Because, to replicate your desired behavior on an asp:Button
, you have to call window.open
on the OnClientClick
event of the button which looks a lot less cleaner than the above solution. Plus asp:HyperLink
is there to handle scenarios like this.
If you want to replicate this using an asp:Button
, do this.
<asp:Button ID="btn" runat="Server"
Text="SUBMIT"
OnClientClick="javascript:return openRequestedPopup();"/>
JavaScript function.
var windowObjectReference;
function openRequestedPopup() {
windowObjectReference = window.open("CMS_1.aspx",
"DescriptiveWindowName",
"menubar=yes,location=yes,resizable=yes,scrollbars=yes,status=yes");
}
The following adds elements to a list in a loop.
l<-c()
i=1
while(i<100) {
b<-i
l<-c(l,b)
i=i+1
}
Use SRV record. If you are using freenom go to cloudflare.com and connect your freenom server to cloudflare (freenom doesn't support srv records) use _minecraft as service tcp as protocol and your ip as target (you need "a" record to use your ip. I recommend not using your "Arboristal.com" domain as "a" record. If you use "Arboristal.com" as your "a" record hackers can go in your router settings and hack your network) priority - 0, weight - 0 and port - the port you want to use.(i know this because i was in the same situation) Do the same for any domain provider. (sorry if i made spell mistakes)
There is no such syntax in SQL Server, though CREATE TABLE AS ... SELECT
does exist in PDW. In SQL Server you can use this query to create an empty table:
SELECT * INTO schema.newtable FROM schema.oldtable WHERE 1 = 0;
(If you want to make a copy of the table including all of the data, then leave out the WHERE
clause.)
Note that this creates the same column structure (including an IDENTITY column if one exists) but it does not copy any indexes, constraints, triggers, etc.
You can't sort a std::map
this way, because a the entries in the map are sorted by the key. If you want to sort by value, you need to create a new std::map
with swapped key and value.
map<long, double> testMap;
map<double, long> testMap2;
// Insert values from testMap to testMap2
// The values in testMap2 are sorted by the double value
Remember that the double keys need to be unique in testMap2
or use std::multimap
.
Actually I would do it this way:
L1 is the index list of elements satisfying condition 1;(maybe you can use somelist.index(condition1)
or np.where(condition1)
to get L1.)
Similarly, you get L2, a list of elements satisfying condition 2;
Then you find intersection using intersect(L1,L2)
.
You can also find intersection of multiple lists if you get multiple conditions to satisfy.
Then you can apply index in any other array, for example, x.

Go to File > Preferences > Settings
(or press Ctrl+,) then click the leftmost icon in the top right corner, "Open Settings (JSON)"
In the JSON settings window, add this (within the curly braces {}
):
"terminal.integrated.shell.windows": "C:\\WINDOWS\\System32\\bash.exe"`
(Here you can put any other custom settings you want as well)
Checkout that path to make sure your bash.exe file is there otherwise find out where it is and point to that path instead.
Now if you open a new terminal window in VS Code, it should open with bash instead of PowerShell.

As I wrote elsewhere
Packaging in Python is dire. The root cause is that the language ships without a package manager.
Fortunately, there is one package manager for Python, called Pip. Pip is inspired by Ruby's Gem, but lacks some features. Ironically, Pip itself is complicated to install. Installation on the popular 64-bit Windows demands building and installing two packages from source. This is a big ask for anyone new to programming.
So the right thing to do is to install pip. However if you can't be bothered, Christoph Gohlke provides binaries for popular Python packages for all Windows platforms http://www.lfd.uci.edu/~gohlke/pythonlibs/
In fact, building some Python packages requires a C compiler (eg. mingw32) and library headers for the dependencies. This can be a nightmare on Windows, so remember the name Christoph Gohlke.
user6779899's answer is neat and more generic However, based on the request by Imad El Hitti, a light weight solution is proposed here. This can be used when a child component is tightly connected to one parent only.
Parent.component.ts
export class Notifier {
valueChanged: (data: number) => void = (d: number) => { };
}
export class Parent {
notifyObj = new Notifier();
tellChild(newValue: number) {
this.notifyObj.valueChanged(newValue); // inform child
}
}
Parent.component.html
<my-child-comp [notify]="notifyObj"></my-child-comp>
Child.component.ts
export class ChildComp implements OnInit{
@Input() notify = new Notifier(); // create object to satisfy typescript
ngOnInit(){
this.notify.valueChanged = (d: number) => {
console.log(`Parent has notified changes to ${d}`);
// do something with the new value
};
}
}
There is a rule in Python programming called "it is Easier to Ask for Forgiveness than for Permission" (in short: EAFP). It means that you should catch exceptions instead of checking values for validity.
Thus, try the following:
try:
qByUser = byUsrUrlObj.read()
qUserData = json.loads(qByUser).decode('utf-8')
questionSubjs = qUserData["all"]["questions"]
except ValueError: # includes simplejson.decoder.JSONDecodeError
print 'Decoding JSON has failed'
EDIT: Since simplejson.decoder.JSONDecodeError
actually inherits from ValueError
(proof here), I simplified the catch statement by just using ValueError
.
This is originally from Sara's blog.
It also works with almost any version of Visual Studio, you just need to change the "8.0" in the registry key to the appropriate version number for your version of Visual Studio.
The guide line shows up in the Output window too. (Visual Studio 2010 corrects this, and the line only shows up in the code editor window.)
You can also have the guide in multiple columns by listing more than one number after the color specifier:
RGB(230,230,230), 4, 80
Puts a white line at column 4 and column 80. This should be the value of a string value Guides
in "Text Editor" key (see bellow).
Be sure to pick a line color that will be visisble on your background. This color won't show up on the default background color in VS. This is the value for a light grey: RGB(221, 221, 221).
Here are the registry keys that I know of:
Visual Studio 2010: HKCU\Software\Microsoft\VisualStudio\10.0\Text Editor
Visual Studio 2008: HKCU\Software\Microsoft\VisualStudio\9.0\Text Editor
Visual Studio 2005: HKCU\Software\Microsoft\VisualStudio\8.0\Text Editor
Visual Studio 2003: HKCU\Software\Microsoft\VisualStudio\7.1\Text Editor
For those running Visual Studio 2010, you may want to install the following extensions rather than changing the registry yourself:

empty

The
empty
operator is a prefix operation that can be used to determine whether a value is null or empty.
<c:if test="${empty myObject.featuresList}">
Here's another:
data[data$Code == "A" | data$Code == "B", ]
It's also worth mentioning that the subsetting factor doesn't have to be part of the data frame if it matches the data frame rows in length and order. In this case we made our data frame from this factor anyway. So,
data[Code == "A" | Code == "B", ]
also works, which is one of the really useful things about R.
Leaving this here just in case anyone needs...
I needed to have custom domains for a Wordpress Multisite setup in IIS Express but nothing worked until I ran Webmatrix/Visual Studio as an Administrator. Then I was able to bind subdomains to the same application.
<bindings>
<binding protocol="http" bindingInformation="*:12345:localhost" />
<binding protocol="http" bindingInformation="*:12345:whatever.localhost" />
</bindings>
Then going to http://whatever.localhost:12345/ will run.
Use the dec argument to set ","
as the decimal point by adding:
ce <- read.table("file.txt", header = TRUE, dec = ",")
just :
mydict = {'A':4,'B':10,'C':0,'D':87}
max(mydict.items(), key=lambda x: x[1])
Once you have your Context and know the name of the database, use:
context.deleteDatabase(DATABASE_NAME);
When this line gets run, the database should be deleted.
The code above will not run in python3 and is less efficient compared to the GCD variants. However, this code is very transparent. It triggered me to create a more compact version:
def imod(a, n):
c = 1
while (c % a > 0):
c += n
return c // a

These days (May 2017), MATLAB still suffer from a robust method to export figures, especially in GNU/Linux systems when exporting figures in batch mode. The best option is to use the extension export_fig
Just download the source code from Github and use it:
plot(cos(linspace(0, 7, 1000)));
set(gcf, 'Position', [100 100 150 150]);
export_fig test2.png
There are all kinds of wonderful ways to specify commits - see the specifying revisions section of man git-rev-parse
for more details. In this case, you probably want:
git diff HEAD@{1}
The @{1}
means "the previous position of the ref I've specified", so that evaluates to what you had checked out previously - just before the pull. You can tack HEAD
on the end there if you also have some changes in your work tree and you don't want to see the diffs for them.
I'm not sure what you're asking for with "the commit ID of my latest version of the file" - the commit "ID" (SHA1 hash) is that 40-character hex right at the top of every entry in the output of git log. It's the hash for the entire commit, not for a given file. You don't really ever need more - if you want to diff just one file across the pull, do
git diff HEAD@{1} filename
This is a general thing - if you want to know about the state of a file in a given commit, you specify the commit and the file, not an ID/hash specific to the file.
You can use DecoratedBox
.
@override
Widget build(BuildContext context) {
return DecoratedBox(
decoration: BoxDecoration(
image: DecorationImage(image: AssetImage("your_asset"), fit: BoxFit.cover),
),
child: Center(child: FlutterLogo(size: 300)),
);
}
Output:
You could use the Request.RawUrl
, Request.Url.OriginalString
, Request.Url.ToString()
or Request.Url.AbsoluteUri
.
Alternatively, you can specify port by running app via command line.
Simply run command:
dotnet run --server.urls http://localhost:5001
Note: Where 5001 is the port you want to run on.
If you are searching for the index of the last occurrence of myvalue
in mylist
:
len(mylist) - mylist[::-1].index(myvalue) - 1
for (int i = 0; i < myList.Length; i++)
{
if (myList[i].Contains(myString)) // (you use the word "contains". either equals or indexof might be appropriate)
{
return i;
}
}
Old fashion loops are almost always the fastest.
Open .iml file. Look for keyword 'NewModuleRootManager'. Check if attribute 'inherit-compiler-output' is set to true or not. If not set to true.
Like this :
component name="NewModuleRootManager" inherit-compiler-output="true">
<content url="file://$MODULE_DIR$">
<sourceFolder url="file://$MODULE_DIR$/test" isTestSource="true" />
<sourceFolder url="file://$MODULE_DIR$/spec" isTestSource="true" />
<sourceFolder url="file://$MODULE_DIR$/app" isTestSource="false" />
There are multiple ways to achieve this.
In case of just for existence. It could be file or a directory.
new File("/path/to/file").exists();
Check for file
File f = new File("/path/to/file");
if(f.exists() && f.isFile()) {}
Check for Directory.
File f = new File("/path/to/file");
if(f.exists() && f.isDirectory()) {}
Java 7 way.
Path path = Paths.get("/path/to/file");
Files.exists(path) // Existence
Files.isDirectory(path) // is Directory
Files.isRegularFile(path) // Regular file
Files.isSymbolicLink(path) // Symbolic Link
I had a similar problem with truncated tar files being produced by a cron job and redirecting standard out to a file fixed the issue.
From talking to a colleague, cron creates a pipe and limits the amount of output that can be sent to standard out. I fixed mine by removing -v from my tar command, making it much less verbose and keeping the error output in the same spot as the rest of my cron jobs. If you need the verbose tar output, you'll need to redirect to a file, though.
Sql Server fire this error when your application don't have enough rights to access the database. there are several reason about this error . To fix this error you should follow the following instruction.
Try to connect sql server from your server using management studio . if you use windows authentication to connect sql server then set your application pool identity to server administrator .
if you use sql server authentication then check you connection string in web.config of your web application and set user id and password of sql server which allows you to log in .
if your database in other server(access remote database) then first of enable remote access of sql server form sql server property from sql server management studio and enable TCP/IP form sql server configuration manager .
after doing all these stuff and you still can't access the database then check firewall of server form where you are trying to access the database and add one rule in firewall to enable port of sql server(by default sql server use 1433 , to check port of sql server you need to check sql server configuration manager network protocol TCP/IP port).
if your sql server is running on named instance then you need to write port number with sql serer name for example 117.312.21.21/nameofsqlserver,1433.
If you are using cloud hosting like amazon aws or microsoft azure then server or instance will running behind cloud firewall so you need to enable 1433 port in cloud firewall if you have default instance or specific port for sql server for named instance.
If you are using amazon RDS or SQL azure then you need to enable port from security group of that instance.
If you are accessing sql server through sql server authentication mode them make sure you enabled "SQL Server and Windows Authentication Mode" sql server instance property.
if you further face any difficulty then you need to provide more information about your web site and sql server .

In line 2, there's a std::string
involved (name
). There are operations defined for char[] + std::string
, std::string + char[]
, etc. "Hello " + name
gives a std::string
, which is added to " you are "
, giving another string, etc.
In line 3, you're saying
char[] + char[] + char[]
and you can't just add arrays to each other.
You need to transform the object you are getting back into an array in the format that jQueryUI expects.
You can use $.map
to transform the dealers
object into that array.
$('#dealerName').autocomplete({
source: function (request, response) {
$.getJSON("/example/location/example.json?term=" + request.term, function (data) {
response($.map(data.dealers, function (value, key) {
return {
label: value,
value: key
};
}));
});
},
minLength: 2,
delay: 100
});
Note that when you select an item, the "key" will be placed in the text box. You can change this by tweaking the label
and value
properties that $.map
's callback function return.
Alternatively, if you have access to the server-side code that is generating the JSON, you could change the way the data is returned. As long as the data:
label
property, a value
property, or both, orIn other words, if you can format the data like this:
[{ value: "1463", label: "dealer 5"}, { value: "269", label: "dealer 6" }]
or this:
["dealer 5", "dealer 6"]
Then your JavaScript becomes much simpler:
$('#dealerName').autocomplete({
source: "/example/location/example.json"
});
Composition is where something is made up of distinct parts and it has a strong relationship with those parts. If the main part dies so do the others, they cannot have a life of their own. A rough example is the human body. Take out the heart and all the other parts die away.
Inheritance is where you just take something that already exists and use it. There is no strong relationship. A person could inherit his fathers estate but he can do without it.
I don't know Java so I cannot provide an example but I can provide an explanation of the concepts.
I'm pretty certain that you can't change the datetime format in mysql. The phpmyadmin setting is probably applying a custom format as it reads the datetime (using DATE_FORMAT or something from php). It shouldn't matter what format the database uses, format in the application to display it as you wish.
Date formatting is a pretty common task. I typically like to abstract it out into internationalization code or, if you don't need to deal with i18n, into a common date utility library. It helps keep things consistent and makes it easier to change later (or add i18n support).
Here's a function to upscale or downscale an image by desired width or height while maintaining aspect ratio
# Resizes a image and maintains aspect ratio
def maintain_aspect_ratio_resize(image, width=None, height=None, inter=cv2.INTER_AREA):
# Grab the image size and initialize dimensions
dim = None
(h, w) = image.shape[:2]
# Return original image if no need to resize
if width is None and height is None:
return image
# We are resizing height if width is none
if width is None:
# Calculate the ratio of the height and construct the dimensions
r = height / float(h)
dim = (int(w * r), height)
# We are resizing width if height is none
else:
# Calculate the ratio of the width and construct the dimensions
r = width / float(w)
dim = (width, int(h * r))
# Return the resized image
return cv2.resize(image, dim, interpolation=inter)
Usage
import cv2
image = cv2.imread('1.png')
cv2.imshow('width_100', maintain_aspect_ratio_resize(image, width=100))
cv2.imshow('width_300', maintain_aspect_ratio_resize(image, width=300))
cv2.waitKey()
Using this example image
Simply downscale to width=100
(left) or upscale to width=300
(right)
You can use a WScript
object and call the Sleep
method on it:
Set WScript = CreateObject("WScript.Shell")
WScript.Sleep 2000 'Sleeps for 2 seconds
Another option is to import and use the WinAPI function directly (only works in VBA, thanks @Helen):
Declare Sub Sleep Lib "kernel32" (ByVal dwMilliseconds As Long)
Sleep 2000
Just for future reference, if you already have a boolean column and you just want to add a default do:
ALTER TABLE users
ALTER COLUMN priv_user SET DEFAULT false;
Try using second parameter for json_decode function:
$json = json_decode(file_get_contents($file), true);
I agree with Chris, checking the extension is not validation of the type of file any way you look at it. Telerik's radUpload is probably your best option, it provides a ContentType property of the file being uploaded, which you can compare to known mime types. You should check for:
application/vnd.ms-excel,

Telerik used to sell radUpload as an individual component, but now its wrapped into the controls suite, which makes it a little more expensive, but by far its the easiest way to check for the true type
You could just make a nice little looping function.
def replace_all(text, dic):
for i, j in dic.iteritems():
text = text.replace(i, j)
return text
where text
is the complete string and dic
is a dictionary — each definition is a string that will replace a match to the term.
Note: in Python 3, iteritems()
has been replaced with items()
Careful: Python dictionaries don't have a reliable order for iteration. This solution only solves your problem if:
Update: The above statement related to ordering of insertion does not apply to Python versions greater than or equal to 3.6, as standard dicts were changed to use insertion ordering for iteration.
For instance:
d = { "cat": "dog", "dog": "pig"}
my_sentence = "This is my cat and this is my dog."
replace_all(my_sentence, d)
print(my_sentence)
Possible output #1:
"This is my pig and this is my pig."
Possible output #2
"This is my dog and this is my pig."
One possible fix is to use an OrderedDict.
from collections import OrderedDict
def replace_all(text, dic):
for i, j in dic.items():
text = text.replace(i, j)
return text
od = OrderedDict([("cat", "dog"), ("dog", "pig")])
my_sentence = "This is my cat and this is my dog."
replace_all(my_sentence, od)
print(my_sentence)
Output:
"This is my pig and this is my pig."
Careful #2: Inefficient if your text
string is too big or there are many pairs in the dictionary.
Tcl has a builtin for this
$ tclsh
% string map {ab bc bc ab} abbc
bcab
This works by walking the string a character at a time doing string comparisons starting at the current position.
In perl:
perl -E '
sub string_map {
my ($str, %map) = @_;
my $i = 0;
while ($i < length $str) {
KEYS:
for my $key (keys %map) {
if (substr($str, $i, length $key) eq $key) {
substr($str, $i, length $key) = $map{$key};
$i += length($map{$key}) - 1;
last KEYS;
}
}
$i++;
}
return $str;
}
say string_map("abbc", "ab"=>"bc", "bc"=>"ab");
'
bcab
Useful to quickly print entries in a HashMap
System.out.println(Arrays.toString(map.entrySet().toArray()));
Put your assets in the public folder

Make sure that the component has the "exported" flag set to true. Also the component defining the permission should be installed before the component that uses it.
You can try this:
$scope.child = {} //declare it in parent controller (scope)
then in child controller (scope) add:
var parentScope = $scope.$parent;
parentScope.child = $scope;
Now the parent has access to the child's scope.
Lets get array list as ArrayList
and new value as value
all you need to do is pass the parameters to .set
method.
ArrayList.set(index,value)
Ex -
ArrayList.set(10,"new value or object")
setArguments()
is useless. It only brings a mess.
public class MyFragment extends Fragment {
public String mTitle;
public String mInitialTitle;
public static MyFragment newInstance(String param1) {
MyFragment f = new MyFragment();
f.mInitialTitle = param1;
f.mTitle = param1;
return f;
}
@Override
public void onSaveInstanceState(Bundle state) {
state.putString("mInitialTitle", mInitialTitle);
state.putString("mTitle", mTitle);
super.onSaveInstanceState(state);
}
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle state) {
if (state != null) {
mInitialTitle = state.getString("mInitialTitle");
mTitle = state.getString("mTitle");
}
...
}
}
TLDR; The best I can come up with is this: (Depending on your use case, there are a number of ways to optimize this function.)
function arrayIndexExists(array, index){
if ( typeof index !== 'number' && index === parseInt(index).toString()) {
index = parseInt(index);
} else {
return false;//to avoid checking typeof again
}
return typeof index === 'number' && index % 1===0 && index >= 0 && array.hasOwnKey(index);
}
The other answer's examples get close and will work for some (probably most) purposes, but are technically quite incorrect for reasons I explain below.
Javascript arrays only use 'numerical' keys. When you set an "associative key" on an array, you are actually setting a property on that array object, not an element of that array. For example, this means that the "associative key" will not be iterated over when using Array.forEach() and will not be included when calculating Array.length. (The exception for this is strings like '0' will resolve to an element of the array, but strings like ' 0' won't.)
Additionally, checking array element or object property that doesn't exist does evaluate as undefined, but that doesn't actually tell you that the array element or object property hasn't been set yet. For example, undefined is also the result you get by calling a function that doesn't terminate with a return statement. This could lead to some strange errors and difficulty debugging code.
This can be confusing, but can be explored very easily using your browser's javascript console. (I used chrome, each comment indicates the evaluated value of the line before it.);
var foo = new Array();
foo;
//[]
foo.length;
//0
foo['bar'] = 'bar';
//"bar"
foo;
//[]
foo.length;
//0
foo.bar;
//"bar"
This shows that associative keys are not used to access elements in the array, but for properties of the object.
foo[0] = 0;
//0
foo;
//[0]
foo.length;
//1
foo[2] = undefined
//undefined
typeof foo[2]
//"undefined"
foo.length
//3
This shows that checking typeof doesn't allow you to see if an element has been set.
var foo = new Array();
//undefined
foo;
//[]
foo[0] = 0;
//0
foo['0']
//0
foo[' 0']
//undefined
This shows the exception I mentioned above and why you can't just use parseInt();
If you want to use associative arrays, you are better off using simple objects as other answers have recommended.
Upon investigation, it's also worth noting that when you want to start using docker in a new terminal window, the correct command is:

PHP runs on the server and Javascript runs on the client, so you can't set a PHP variable to equal a Javascript variable without sending the value to the server. You can, however, set a Javascript variable to equal a PHP variable:
<script type="text/javascript">
var foo = '<?php echo $foo ?>';
</script>
To send a Javascript value to PHP you'd need to use AJAX. With jQuery, it would look something like this (most basic example possible):
var variableToSend = 'foo';
$.post('file.php', {variable: variableToSend});
On your server, you would need to receive the variable sent in the post:
$variable = $_POST['variable'];
There is a built-in function in jQuery to check this (isNumeric), so try the following:
var phone = $("input#phone").val();
if (phone !== "" && !$.isNumeric(phone)) {
//Check if phone is numeric
$("label#phone_error").show(); //Show error
$("input#phone").focus(); //Focus on field
return false;
}
Just add below lines to your /etc/phpmyadmin/config.inc.php
file in the bottom:
$i++;
$cfg['Servers'][$i]['host'] = 'HostName:port'; //provide hostname and port if other than default
$cfg['Servers'][$i]['user'] = 'userName'; //user name for your remote server
$cfg['Servers'][$i]['password'] = 'Password'; //password
$cfg['Servers'][$i]['auth_type'] = 'config'; // keep it as config
You will get Current Server:
drop down with both 127.0.0.1
and one what you have provided with $cfg['Servers'][$i]['host']
can switch between the servers.

Angular Component
A component is one of the basic building blocks of an Angular app. An app can have more than one component. In a normal app, a component contains an HTML view page class file, a class file that controls the behaviour of the HTML page and the CSS/scss file to style your HTML view. A component can be created using @Component
decorator that is part of @angular/core
module.
import { Component } from '@angular/core';
and to create a component
@Component({selector: 'greet', template: 'Hello {{name}}!'})
class Greet {
name: string = 'World';
}
To create a component or angular app here is the tutorial
Angular Module
An angular module is set of angular basic building blocks like component, directives, services etc. An app can have more than one module.
A module can be created using @NgModule
decorator.
@NgModule({
imports: [ BrowserModule ],
declarations: [ AppComponent ],
bootstrap: [ AppComponent ]
})
export class AppModule { }
I work with telerik radcontrols that's why I Find a control, but you can find control directly like: $('#IdExample').css({
this code works for me, I hope help you and sorry my english.
Code Javascript:
<script type="javascript">
function changeToUpperCase(event, obj) {
var txtDescripcion = $("#%=RadPanelBar1.Items(0).Items(0).FindControl("txtDescripcion").ClientID%>");
txtDescripcion.css({
"text-transform": "uppercase"
});
} </script>
Code ASP.NET
<asp:TextBox ID="txtDescripcion" runat="server" MaxLength="80" Width="500px" onkeypress="return changeToUpperCase(event,this)"></asp:TextBox>
You can use Kotlin-coroutines
class YoutActivity : AppCompatActivity, CoroutineScope {
override fun onCreate(...) {
launch { yourHeavyMethod() }
}
suspend fun yourHeavyMethod() {
with(Dispatchers.IO){ yourNetworkCall() }
...
...
}
}
You can follow this guide.
If you just want to change the port because it is already in use. Follow the following steps.
In Visual studio
<DevelopmentServerPort>62140</DevelopmentServerPort> <DevelopmentServerVPath></DevelopmentServerVPath> <IISUrl>http://localhost:62116/</IISUrl>
It will work by selecting another port randomly.

I just used Homebrew to go back to Maven 2.2.1 since the simple brew install maven
installed Maven 3.0.3.
First you have to leave the maven dir there so
$ brew unlink maven
Use the brew tap command
$ brew tap homebrew/versions Cloning into '/usr/local/Library/Taps/homebrew-versions'... remote: Counting objects: 590, done. remote: Compressing objects: 100% (265/265), done. remote: Total 590 (delta 362), reused 549 (delta 325) Receiving objects: 100% (590/590), 117.49 KiB | 79 KiB/s, done. Resolving deltas: 100% (362/362), done. Tapped 50 formula
Now you can install the maven2 formula:
$ brew install maven2 ==> Downloading http://www.apache.org/dist/maven/maven-2/2.2.1/binaries/apache-maven-2.2.1-bin.tar.gz ######################################################################## 100.0% /usr/local/Cellar/maven2/2.2.1: 10 files, 3.1M, built in 6 seconds

Edit:
You can also just brew switch maven 2.2.1
to switch to a different version.
Edit: The Apache Maven project reorganized their repo. Updated this answer to account for this change.
I've found examples, where PyPy is slower than Python. But: Only on Windows.
C:\Users\User>python -m timeit -n10 -s"from sympy import isprime" "isprime(2**521-1);isprime(2**1279-1)"
10 loops, best of 3: 294 msec per loop
C:\Users\User>pypy -m timeit -n10 -s"from sympy import isprime" "isprime(2**521-1);isprime(2**1279-1)"
10 loops, best of 3: 1.33 sec per loop
So, if you think of PyPy, forget Windows. On Linux, you can achieve awesome accelerations. Example (list all primes between 1 and 1,000,000):
from sympy import sieve
primes = list(sieve.primerange(1, 10**6))
This runs 10(!) times faster on PyPy than on Python. But not on windows. There it is only 3x as fast.
Your sklearn version is too low, model_selection
is imported by 0.18.1, so please update the sklearn version.
In my case I had this referenceError as the order of script calls was wrong. Solved that by changing the order:

<script src="js/jquery-1.10.2.js"></script>
<script src="js/index.js"></script>
Behavior difference: clicking in the space between label and input
If you click on the space between the label and the input it activates the input only if the label contains the input.
This makes sense since in this case the space is just another character of the label.
<p>Inside:</p>_x000D_
_x000D_
<label>_x000D_
<input type="checkbox" />_x000D_
|<----- Label. Click between me and the checkbox._x000D_
</label>_x000D_
_x000D_
<p>Outside:</p>_x000D_
_x000D_
<input type="checkbox" id="check" />_x000D_
<label for="check">|<----- Label. Click between me and the checkbox.</label>
_x000D_
Being able to click between label and box means that it is:
Bootstrap checkbox v3.3 examples use the input inside: http://getbootstrap.com/css/#forms Might be wise to follow them. But they changed their minds in v4.0 https://getbootstrap.com/docs/4.0/components/forms/#checkboxes-and-radios so I don't know what is wise anymore:
Checkboxes and radios use are built to support HTML-based form validation and provide concise, accessible labels. As such, our
<input>
s and<label>
s are sibling elements as opposed to an<input>
within a<label>
. This is slightly more verbose as you must specify id and for attributes to relate the<input>
and<label>
.
UX question that discusses this point in detail: https://ux.stackexchange.com/questions/23552/should-the-space-between-the-checkbox-and-label-be-clickable
The way a cherry-pick works is by taking the diff a changeset represents (the difference between the working tree at that point and the working tree of its parent), and applying it to your current branch.
So, if a commit has two or more parents, it also represents two or more diffs - which one should be applied?
You're trying to cherry pick fd9f578
, which was a merge with two parents. So you need to tell the cherry-pick command which one against which the diff should be calculated, by using the -m
option. For example, git cherry-pick -m 1 fd9f578
to use parent 1 as the base.
I can't say for sure for your particular situation, but using git merge
instead of git cherry-pick
is generally advisable. When you cherry-pick a merge commit, it collapses all the changes made in the parent you didn't specify to -m
into that one commit. You lose all their history, and glom together all their diffs. Your call.
What you are doing is making a JSON string in your example. Either don't use the JSON.stringify()
or if you ever do have JSON data coming back and you don't want quotations, Simply use JSON.parse()
to remove quotations around JSON responses! Don't use regex, there's no need to.

On a mac if you install xattr
in python, then your environment may have an issue.
There are two different paths on my mac for
xattr
type -a xattr
# xattr is /usr/local/bin/xattr # PYTHON Installed Version
# xattr is /usr/bin/xattr # Mac OSX Installed Version
So in one of the example's where -c
will not work in xargs is because in bash you default to the non-python version.
-c
/usr/bin/xattr -c
-c
/usr/local/bin/xattr -c
# option -c not recognized
My Shell/Terminal defaults to /usr/local/bin/xattr because my $PATH
/usr/local/bin:
is before /usr/bin:
which I believe is the default.
I can prove this because, if you try to uninstall the python xattr
you will see:
pip3 uninstall xattr
Uninstalling xattr-0.9.6:
Would remove:
/usr/local/bin/xattr
/usr/local/lib/python3.7/site-packages/xattr-0.9.6.dist-info/*
/usr/local/lib/python3.7/site-packages/xattr/*
Proceed (y/n)?
To Fix option -c not recognized
Errors.
xattr
you may have: pip3 uninstall xattr
Terminal
windows & quit Terminal
Terminal
window.xattr
command and it should now work.OR
If you want to keep the Python
xattr
then use
/usr/bin/xattr
for any Shell
commands in Terminal
Python's version of xattr
doesn't handle images at all:

Please use following CSS properties for center align element horizontally as well as vertically. This is worked fine for me.
div {

width: 100px;
height: 100px;

If forcing a push doesn't help ("git push --force origin
" or "git push --force origin master
" should be enough), it might mean that the remote server is refusing non fast-forward pushes either via receive.denyNonFastForwards config variable (see git config manpage for description), or via update / pre-receive hook.
With older Git you can work around that restriction by deleting "git push origin :master
" (see the ':' before branch name) and then re-creating "git push origin master
" given branch.
If you can't change this, then the only solution would be instead of rewriting history to create a commit reverting changes in D-E-F:
A-B-C-D-E-F-[(D-E-F)^-1] master A-B-C-D-E-F origin/master
As others have answered, the mysqli API can execute multi-queries with the msyqli_multi_query() function.
For what it's worth, PDO supports multi-query by default, and you can iterate over the multiple result sets of your multiple queries:
$stmt = $dbh->prepare("
select sql_calc_found_rows * from foo limit 1 ;
select found_rows()");
$stmt->execute();
do {
while ($row = $stmt->fetch()) {
print_r($row);
}
} while ($stmt->nextRowset());
However, multi-query is pretty widely considered a bad idea for security reasons. If you aren't careful about how you construct your query strings, you can actually get the exact type of SQL injection vulnerability shown in the classic "Little Bobby Tables" XKCD cartoon. When using an API that restrict you to single-query, that can't happen.
After I tried algirdas' solution, my Windows crashed (Win 7 Pro 64bit) so I decided to try a different solution:
Run
(Win+R)cmd /K chcp 65001
You will get mostly what you want. To start it from the taskbar or anywhere else, make a shortcut (you can name it cmd.unicode.exe
or whatever you like) and change its Target
to C:\Windows\System32\cmd.exe /K chcp 65001
.
If you want your requests to persists try this:
example: on your JSP or servlet page
request.getSession().setAttribute("SUBFAMILY", subFam);
and on any receiving page use the below lines to retrieve your session and data:
SubFamily subFam = (SubFamily)request.getSession().getAttribute("SUBFAMILY");
I'd highly recommend the Castle DictionaryAdapter, easily one of that project's best-kept secrets. You only need to define an interface with the properties you want, and in one line of code the adapter will generate an implementation, instantiate it, and synchronize its values with a dictionary you pass in. I use it to strongly-type my AppSettings in a web project:
var appSettings =
new DictionaryAdapterFactory().GetAdapter<IAppSettings>(ConfigurationManager.AppSettings);
Note that I did not need to create a class that implements IAppSettings - the adapter does that on the fly. Also, although in this case I'm only reading, in theory if I were setting property values on appSettings, the adapter would keep the underlying dictionary in sync with those changes.
I would think that one reason could be that the color is applied to things other than font. For example:
div {
border: 1px solid;
color: red;
}
Yields both a red font color and a red border.
Alternatively, it could just be that the W3C's CSS standards are completely backwards and nonsensical as evidenced elsewhere.
Try:
if($("option[value='parcel']").is(":checked"))
$('#row_dim').show();
Or even:
$(function() {
$('#type').change(function(){
$('#row_dim')[ ($("option[value='parcel']").is(":checked"))? "show" : "hide" ]();
});
});

You could try simply blocking the context menu by adding the following to your body tag:
<body oncontextmenu="return false;">
This will block all access to the context menu (not just from the right mouse button but from the keyboard as well).
P.S. you can add this to any tag you want to disable the context menu on
for example:
<div class="mydiv" oncontextmenu="return false;">
Will disable the context menu in that particular div only
It would be a good suggestion to use an already built-in function but another way around is to:
The benefit behind using the sp_rename
is that it takes care of all the relations associated with it.
From the documentation:
sp_rename automatically renames the associated index whenever a PRIMARY KEY or UNIQUE constraint is renamed. If a renamed index is tied to a PRIMARY KEY constraint, the PRIMARY KEY constraint is also automatically renamed by sp_rename. sp_rename can be used to rename primary and secondary XML indexes.

One way is to use re.sub, that's my preferred way.
import re
my_str = "hey th~!ere"
my_new_string = re.sub('[^a-zA-Z0-9 \n\.]', '', my_str)
print my_new_string
Output:
hey there
Another way is to use re.escape:
import string
import re
my_str = "hey th~!ere"
chars = re.escape(string.punctuation)
print re.sub(r'['+chars+']', '',my_str)
Output:
hey there
Just a small tip about parameters style in python by PEP-8 parameters should be remove_special_chars
and not removeSpecialChars
Also if you want to keep the spaces just change [^a-zA-Z0-9 \n\.]
to [^a-zA-Z0-9\n\.]

Android has always had the Uri class as part of the SDK: http://developer.android.com/reference/android/net/Uri.html
You can simply do something like:
String requestURL = String.format("http://www.example.com/?a=%s&b=%s", Uri.encode("foo bar"), Uri.encode("100% fubar'd"));
You could use the String.charAt(int index)
method result as the parameter for String.valueOf(char c).
String.valueOf(myString.charAt(3)) // This will return a string of the character on the 3rd position.
A quick performance test showing Lutz's solution is the best:
import time
def speed_test(func):
def wrapper(*args, **kwargs):
t1 = time.time()
for x in xrange(5000):
results = func(*args, **kwargs)
t2 = time.time()
print '%s took %0.3f ms' % (func.func_name, (t2-t1)*1000.0)
return results
return wrapper
@speed_test
def compare_bitwise(x, y):
set_x = frozenset(x)
set_y = frozenset(y)
return set_x & set_y
@speed_test
def compare_listcomp(x, y):
return [i for i, j in zip(x, y) if i == j]
@speed_test
def compare_intersect(x, y):
return frozenset(x).intersection(y)
# Comparing short lists
a = [1, 2, 3, 4, 5]
b = [9, 8, 7, 6, 5]
compare_bitwise(a, b)
compare_listcomp(a, b)
compare_intersect(a, b)
# Comparing longer lists
import random
a = random.sample(xrange(100000), 10000)
b = random.sample(xrange(100000), 10000)
compare_bitwise(a, b)
compare_listcomp(a, b)
compare_intersect(a, b)
These are the results on my machine:
# Short list:
compare_bitwise took 10.145 ms
compare_listcomp took 11.157 ms
compare_intersect took 7.461 ms
# Long list:
compare_bitwise took 11203.709 ms
compare_listcomp took 17361.736 ms
compare_intersect took 6833.768 ms
Obviously, any artificial performance test should be taken with a grain of salt, but since the set().intersection()
answer is at least as fast as the other solutions, and also the most readable, it should be the standard solution for this common problem.
You don't need bindingSource1
Just set dataGridView1.DataSource = table;
The above solutions like run a query
SET session wait_timeout=600;
Will only work until mysql is restarted. For a persistant solution, edit mysql.conf and add after [mysqld]:
wait_timeout=300
interactive_timeout = 300
Where 300 is the number of seconds you want.
The psql \o
command was already described by jhwist.
An alternative approach is using the COPY TO
command to write directly to a file on the server. This has the advantage that it's dumped in an easy-to-parse format of your choice -- rather than psql's tabulated format. It's also very easy to import to another table/database using COPY FROM
.
NB! This requires superuser privileges and will write to a file on the server.
Example: COPY (SELECT foo, bar FROM baz) TO '/tmp/query.csv' (format csv, delimiter ';')
Creates a CSV file with ';' as the field separator.
As always, see the documentation for details
I think that Spring Data ignores the FetchMode. I always use the @NamedEntityGraph
and @EntityGraph
annotations when working with Spring Data
@Entity
@NamedEntityGraph(name = "GroupInfo.detail",
attributeNodes = @NamedAttributeNode("members"))
public class GroupInfo {
// default fetch mode is lazy.
@ManyToMany
List<GroupMember> members = new ArrayList<GroupMember>();
…
}
@Repository
public interface GroupRepository extends CrudRepository<GroupInfo, String> {
@EntityGraph(value = "GroupInfo.detail", type = EntityGraphType.LOAD)
GroupInfo getByGroupName(String name);
}

do while in an exit control loop. while is an entry control loop.
How not to do it:
When building an image, you could also tag it this way.
docker build -t ubuntu:14.04 .
Then you build it again with another tag:
docker build -t ubuntu:latest .
If your Dockerfile makes good use of the cache, the same image should come out, and it effectively does the same as retagging the same image. If you do docker images
then you will see that they have the same ID.
There's probably a case where this goes wrong though... But like @david-braun said, you can't create tags with Dockerfiles themselves, just with the docker command.
I'm sorry to necro an old post - but I found a better way of doing this
What I believe this poster wanted was :
<label for="mydropdown" datalabel="mydropdown">Country:</label>
<select name="mydropdown">
<option value="United States">United States</option>
<option value="Canada">Canada</option>
<option value="Mexico">Mexico</option>
<option value="Other">Not Listed</option>
</select>
I found this information in another post while searching for this same answer - Thanks
Besides authentication, I suggest you think about the big picture. Consider make your backend RESTful service without any authentication; then put some very simple authentication required middle layer service between the end user and the backend service.
If still getting error then follow the steps of mysql2 gem installation on Rails 3 on -
http://rorguide.blogspot.com/2011/03/installing-mysql2-gem-on-ruby-192-and.html
where most of the user were able to install mysql2 gem.
I would simply do this, which literally follows what your desired logic was:
df.groupby(['org']).mean().groupby(['cluster']).mean()
Most of the time, the problem is due to some error on the human side. In my case, I was using some classes whose names are similar. I have added the empty() method under one class; however, my code was calling the empty() method from another class. At that moment, the mind was stuck. I was running make clean, and remake thinking that it was some older version of the header got used. After walking away for a moment, I found that problem right away. We programmers tends to blame others first. Maybe we should insist on ourselves to be wrong first.
Sometimes, I forget to write the latest update to disk and looking at the correct version of the code, but the compiler is seeing the wrong version of the code. This situation may be less a issue on IDE (I use vi to do coding).

Example of extension String:
private typealias HowDoYouLikeThatElonMusk = String
private extension HowDoYouLikeThatElonMusk {
subscript(_ from: Character?, _ to: Character?, _ include: Bool) -> String? {
if let _from: Character = from, let _to: Character = to {
let dynamicSourceForEnd: String = (_from == _to ? String(self.reversed()) : self)
guard let startOfSentence: String.Index = self.index(of: _from),
let endOfSentence: String.Index = dynamicSourceForEnd.index(of: _to) else {
return nil
}
let result: String = String(self[startOfSentence...endOfSentence])
if include == false {
guard result.count > 2 else {
return nil
}
return String(result[result.index(result.startIndex, offsetBy: 1)..<result.index(result.endIndex, offsetBy: -1)])
}
return result
} else if let _from: Character = from {
guard let startOfSentence: String.Index = self.index(of: _from) else {
return nil

}
let result: String = String(self[...endOfSentence])
if include == false {
guard result.count > 1 else {
return nil
}
return String(result[..<result.index(result.endIndex, offsetBy: -1)])
}
return result
}
return nil
}
}
example of using the extension String:
let source = ">>>01234..56789<<<"
// include = true
var from = source["3", nil, true] // "34..56789<<<"
var to = source[nil, "6", true] // ">>>01234..56"
var fromTo = source["3", "6", true] // "34..56"
let notFound = source["a", nil, true] // nil
// include = false
from = source["3", nil, false] // "4..56789<<<"
to = source[nil, "6", false] // ">>>01234..5"
fromTo = source["3", "6", false] // "4..5"
let outOfBounds = source[".", ".", false] // nil
let str = "Hello, playground"
let hello = str[nil, ",", false] // "Hello"
I had almost just as same error with my Ruby on Rails application running postgresql(mac). This worked for me:
brew services restart postgresql
Simple way:
String strSQL = "UPDATE myTable SET Column1 = someValue WHERE columnId = "+ someValue;
myDataBase.execSQL(strSQL);
I was facing the same issue while executing the command mvn -version; however, I checked I had also set the mvn options in the environment variables setting, which gave me some Heap memory issue on the command prompt. So, I removed the maven options that I had set and then it worked fine for me.
Found the answer in How to lay out Views in RelativeLayout programmatically?
We should explicitly set id's using setId(). Only then, RIGHT_OF rules make sense.
Another mistake I did is, reusing the layoutparams object between the controls. We should create new object for each control
if you are using jquery-validate.js
in your application then use below expression.
if($("#spa").is(":blank"))

There's no such thing as a "complete" list. Different people have different ways of measuring -- for example, they might include slang, neologisms, multi-word phrases, offensive terms, foreign words, verb conjugations, and so on. Some people have even counted a million words! So you'll have to decide what you want in a word list.
The NVARCHAR2 datatype was introduced by Oracle for databases that want to use Unicode for some columns while keeping another character set for the rest of the database (which uses VARCHAR2). The NVARCHAR2 is a Unicode-only datatype.
One reason you may want to use NVARCHAR2 might be that your DB uses a non-Unicode character set and you still want to be able to store Unicode data for some columns without changing the primary character set. Another reason might be that you want to use two Unicode character set (AL32UTF8 for data that comes mostly from western Europe, AL16UTF16 for data that comes mostly from Asia for example) because different character sets won't store the same data equally efficiently.
Both columns in your example (Unicode VARCHAR2(10 CHAR)
and NVARCHAR2(10)
) would be able to store the same data, however the byte storage will be different. Some strings may be stored more efficiently in one or the other.
Note also that some features won't work with NVARCHAR2, see this SO question:

In ~/Views/ViewStart.cshtml
:
@{
Layout = Request.IsAjaxRequest() ? null : "~/Views/Shared/_Layout.cshtml";
}
and in the controller:
public ActionResult Index()
{
return View();
}
The commands dict.items()
, dict.keys()
and dict.values()
return a copy of the dictionary's list of (k, v)
pair, keys and values.
This could take a lot of memory if the copied list is very large.
The commands dict.iteritems()
, dict.iterkeys()
and dict.itervalues()
return an iterator over the dictionary’s (k, v)
pair, keys and values.
The commands dict.viewitems()
, dict.viewkeys()
and dict.viewvalues()
return the view objects, which can reflect the dictionary's changes.
(I.e. if you del
an item or add a (k,v)
pair in the dictionary, the view object can automatically change at the same time.)
$ python2.7
>>> d = {'one':1, 'two':2}
>>> type(d.items())
<type 'list'>
>>> type(d.keys())
<type 'list'>
>>>
>>>
>>> type(d.iteritems())
<type 'dictionary-itemiterator'>
>>> type(d.iterkeys())
<type 'dictionary-keyiterator'>
>>>
>>>
>>> type(d.viewitems())
<type 'dict_items'>
>>> type(d.viewkeys())
<type 'dict_keys'>
In Py3.x, things are more clean, since there are only dict.items()
, dict.keys()
and dict.values()
available, which return the view objects just as dict.viewitems()
in Py2.x did.
Just as @lvc noted, view object isn't the same as iterator, so if you want to return an iterator in Py3.x, you could use iter(dictview)
:
$ python3.3
>>> d = {'one':'1', 'two':'2'}
>>> type(d.items())
<class 'dict_items'>
>>>
>>> type(d.keys())
<class 'dict_keys'>
>>>
>>>
>>> ii = iter(d.items())
>>> type(ii)
<class 'dict_itemiterator'>
>>>
>>> ik = iter(d.keys())
>>> type(ik)
<class 'dict_keyiterator'>

Just go to the Developer option in your phone and disable and again enable usb debugging. It will work.
Try the following script:
#!/bin/bash
pgrep $1 2>&1 > /dev/null
if [ $? -eq 0 ]
then
{
echo " "$1" PROCESS RUNNING "
ps -ef | grep $1 | grep -v grep | awk '{print $2}'| xargs kill -9
}
else
{
echo " NO $1 PROCESS RUNNING"
};fi
This should do it:
var fn = arguments.callee.toString().match(/function\s+([^\s\(]+)/);
alert(fn[1]);
For the caller, just use caller.toString()
.
For this stuff no need to lot's of coding it's very easy like below code:-
your all textfiled in UIScrollview from nib like this image:-
YourViewController.h
@interface cntrInquiryViewController : UIViewController<UIScrollViewDelegate,UITextFieldDelegate>
{
IBOutlet UITextField *txtName;
IBOutlet UITextField *txtEmail;
IBOutlet UIScrollView *srcScrollView;
}
@end
connect IBOutlet from nib and also Connect each delegate of UItextfiled and scrollview delegate from NIB
-(void)viewWillAppear:(BOOL)animated
{
srcScrollView.contentSize = CGSizeMake(320, 500);
[super viewWillAppear:YES];
}
-(void)textFieldDidBeginEditing:(FMTextField *)textField
{
[srcScrollView setContentOffset:CGPointMake(0,textField.center.y-140) animated:YES];//you can set your y cordinate as your req also
}
-(BOOL)textFieldShouldReturn:(UITextField *)textField
{
[textField resignFirstResponder];
[srcScrollView setContentOffset:CGPointMake(0,0) animated:YES];
return YES;
}
NOTE if Text-filed delegate not connected then no one method working please insure that all iBOulate and delegate connected correctly
If you are using plain LINQ-to-objects and don't want to take a dependency on an external library it is not hard to achieve what you want.
The OrderBy()
clause accepts a Func<TSource, TKey>
that gets a sort key from a source element. You can define the function outside the OrderBy()
clause:
Func<Item, Object> orderByFunc = null;
You can then assign it to different values depending on the sort criteria:
if (sortOrder == SortOrder.SortByName)
orderByFunc = item => item.Name;
else if (sortOrder == SortOrder.SortByRank)
orderByFunc = item => item.Rank;
Then you can sort:
var sortedItems = items.OrderBy(orderByFunc);
This example assumes that the source type is Item
that have properties Name
and Rank
.
Note that in this example TKey
is Object
to not constrain the property types that can be sorted on. If the func returns a value type (like Int32
) it will get boxed when sorting and that is somewhat inefficient. If you can constrain TKey
to a specific value type you can work around this problem.
To diagnose better, you can capture the standard output and standard error streams of the external program, in order to see what output was generated and why it might not be running as expected.
Look up:
If you set each of those to true, then you can later call process.StandardOutput.ReadToEnd()
and process.StandardError.ReadToEnd()
to get the output into string variables, which you can easily inspect under the debugger, or output to trace or your log file.
var today = new Date().toISOString().split('T')[0];
$("#datePicker").val(today);
Above code will work.
int main()
{
int m;
while(cin>>m)
{
}
}
This would read from standard input if it space separated or line separated .
You could use width: 100%;

You can use Node.js for Mobile Apps.
It works on Android devices and simulators, with pre-built binaries for armeabi-v7a, x86, arm64-v8a, x86_64. It also works on iOS, though that's outside the scope of this question.
Like JXcore, it is used to host a Node.js engine in the same process as the app, in a dedicated thread. Unlike JXcore, it is basically pure Node.js, built as a library, with a few portability fixes to run on Android. This means that it's much easier to keep the project up to date with mainline Node.js.
Plugins for Cordova and React Native are also available. The plugins provide a communication layer between the JavaScript side of those frameworks and the Node.js side. They also simplify development by taking care of a few things automatically, like packaging modules and cross-compiling native modules at build time.
Full disclosure: I work for the company that develops Node.js for Mobile Apps.
You are correct that you can omit it. It's useful only for clarity. There is no functional difference between it being there and not being there.

what are you exactly want check for login or user ? a login is created on server level and a user is created at database level so a login is unique in server
also a user is created against a login, a user without login is an orphaned user and is not useful as u cant carry out sql server login without a login
maybe u need this
check for login
select 'X' from master.dbo.syslogins where loginname=<username>
the above query return 'X' if login exists else return null
then create a login
CREATE LOGIN <username> with PASSWORD=<password>
this creates a login in sql server .but it accepts only strong passwords
create a user in each database you want to for login as
CREATE USER <username> for login <username>
assign execute rights to user
GRANT EXECUTE TO <username>
YOU MUST HAVE SYSADMIN permissions or say 'sa' for short
you can write a sql procedure for that on a database
create proc createuser
(
@username varchar(50),
@password varchar(50)
)
as
begin
if not exists(select 'X' from master.dbo.syslogins where loginname=@username)
begin
if not exists(select 'X' from sysusers where name=@username)
begin
exec('CREATE LOGIN '+@username+' WITH PASSWORD='''+@password+'''')
exec('CREATE USER '+@username+' FOR LOGIN '+@username)
exec('GRANT EXECUTE TO '+@username)
end
end
end
.print:last-child{

page-break-inside: avoid;

This worked for me.
You can further simplify the accepted answer. Instead of typing out the enums as strings in xaml and doing more work in your converter than needed, you can explicitly pass in the enum value instead of a string representation, and as CrimsonX commented, errors get thrown at compile time rather than runtime:
<StackPanel>
<StackPanel.Resources>
<local:ComparisonConverter x:Key="ComparisonConverter" />
</StackPanel.Resources>
<RadioButton IsChecked="{Binding Path=YourEnumProperty, Converter={StaticResource ComparisonConverter}, ConverterParameter={x:Static local:YourEnumType.Enum1}}" />
<RadioButton IsChecked="{Binding Path=YourEnumProperty, Converter={StaticResource ComparisonConverter}, ConverterParameter={x:Static local:YourEnumType.Enum2}}" />
</StackPanel>
Then simplify the converter:
public class ComparisonConverter : IValueConverter
{
public object Convert(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture)
{
return value?.Equals(parameter);
}
public object ConvertBack(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture)
{
return value?.Equals(true) == true ? parameter : Binding.DoNothing;
}
}
ConverterParameter={x:Static local:YourClass+YourNestedEnumType.Enum1}
Due to this Microsoft Connect Issue, however, the designer in VS2010 will no longer load stating "Type 'local:YourClass+YourNestedEnumType' was not found."
, but the project does compile and run successfully. Of course, you can avoid this issue if you are able to move your enum type to the namespace directly.
public class EnumToBooleanConverter : IValueConverter
{
public object Convert(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture)
{
return ((Enum)value).HasFlag((Enum)parameter);
}
public object ConvertBack(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture)
{
return value.Equals(true) ? parameter : Binding.DoNothing;
}
}
public object Convert(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture)
{
if (value == null) {
return false; // or return parameter.Equals(YourEnumType.SomeDefaultValue);
}
return value.Equals(parameter);
}
IsChecked
is a nullable type so returning Nullable<Boolean>
seems a reasonable solution.
I have seen such error and i solved it. You may have missing values in your data set. Number of observations in every column must also be the same.
Update 1
I have modified it to use StreamWriter instead, add an option to check if you need column headers in your output.
public static bool DataTableToCSV(DataTable dtSource, StreamWriter writer, bool includeHeader)
{
if (dtSource == null || writer == null) return false;
if (includeHeader)
{
string[] columnNames = dtSource.Columns.Cast<DataColumn>().Select(column => "\"" + column.ColumnName.Replace("\"", "\"\"") + "\"").ToArray<string>();
writer.WriteLine(String.Join(",", columnNames));
writer.Flush();
}
foreach (DataRow row in dtSource.Rows)
{
string[] fields = row.ItemArray.Select(field => "\"" + field.ToString().Replace("\"", "\"\"") + "\"").ToArray<string>();
writer.WriteLine(String.Join(",", fields));
writer.Flush();
}
return true;
}
As you can see, you can choose the output by initial StreamWriter, if you use StreamWriter(Stream BaseStream), you can write csv into MemeryStream, FileStream, etc.
Origin
I have an easy datatable to csv function, it serves me well:
public static void DataTableToCsv(DataTable dt, string csvFile)
{
StringBuilder sb = new StringBuilder();
var columnNames = dt.Columns.Cast<DataColumn>().Select(column => "\"" + column.ColumnName.Replace("\"", "\"\"") + "\"").ToArray();
sb.AppendLine(string.Join(",", columnNames));
foreach (DataRow row in dt.Rows)
{
var fields = row.ItemArray.Select(field => "\"" + field.ToString().Replace("\"", "\"\"") + "\"").ToArray();
sb.AppendLine(string.Join(",", fields));
}
File.WriteAllText(csvFile, sb.ToString(), Encoding.Default);
}
Use the Figure.savefig()
method, like so:
ax = s.hist() # s is an instance of Series
fig = ax.get_figure()
fig.savefig('/path/to/figure.pdf')
It doesn't have to end in pdf
, there are many options. Check out the documentation.
Alternatively, you can use the pyplot
interface and just call the savefig
as a function to save the most recently created figure:
import matplotlib.pyplot as plt
s.hist()
plt.savefig('path/to/figure.pdf') # saves the current figure
Go to command windows (cmd) then type:
"c:\Progam Files(x86)\GnuWin32\bin\awk"
Those are called #include guards.
Once the header is included, it checks if a unique value (in this case HEADERFILE_H
) is defined. Then if it's not defined, it defines it and continues to the rest of the page.
When the code is included again, the first ifndef
fails, resulting in a blank file.
That prevents double declaration of any identifiers such as types, enums and static variables.
If you are linking to many files, create a whitelist, and then use sendFile():
app.get('/npm/:pkg/:file', (req, res) => {
const ok = ['jquery','bootstrap','interactjs'];
if (!ok.includes(req.params.pkg)) res.status(503).send("Not Permitted.");
res.sendFile(__dirname + `/node_modules/${req.params.pkg}/dist/${req.params.file}`);
});
For example, You can then safely link to /npm/bootstrap/bootsrap.js, /npm/bootstrap/bootsrap.css, etc.
As an aside, I would love to know if there was a way to whitelist using express.static
The most readable way is
x = 10 if a > b else 11
but you can use and
and or
, too:
x = a > b and 10 or 11
The "Zen of Python" says that "readability counts", though, so go for the first way.
Also, the and-or trick will fail if you put a variable instead of 10
and it evaluates to False
.
However, if more than the assignment depends on this condition, it will be more readable to write it as you have:
if A[i] > B[j]:
x = A[i]
i += 1
else:
x = A[j]
j += 1
unless you put i
and j
in a container. But if you show us why you need it, it may well turn out that you don't.
I know this is pretty old, but ran across this while trying to accomplish almost the same thing. Found this solution in RegEx Buddy. This pattern will replace all double spaces with single spaces and also trim leading and trailing spaces.
pattern: (?m:^ +| +$|( ){2,})
replacement: $1
Its a little difficult to read since we're dealing with empty space, so here it is again with the "spaces" replaced with a "_".
pattern: (?m:^_+|_+$|(_){2,}) <-- don't use this, just for illustration.
The "(?m:" construct enables the "multi-line" option. I generally like to include whatever options I can within the pattern itself so it is more self contained.
If your server is Apache, you should be able to configure it to see the repository list with viewvc - this is the most basic one, other more complex interfaces exist but this is not your purpose here.
In some versions, ViewVC is an option of the standard installation now, for instance from Collabnet.
Edit: Nevermind my previous idea just above, Peter has a much simpler way of sending the repository list.
From there, you will have to:
Unfortunately in this case I cannot think of something more straightforward.
There are examples on SO on how to extract text from HTML pages in Python, this would be a good option since Python also has bindings for SVN, to perform the repository search - you can still call svn
directly from Python if you prefer.
If Python is not your cup of tea, you will have to process that differently with GNU tools (wget, then parsing tools or existing packages - I can't be of much help there, Carl gave you some more details in this post).
Perl is a context-based language. It doesn't do its work according to the data you give it. Instead, it figures out how to treat the data based on the operators you use and the context in which you use them. If you do numbers sorts of things, you get numbers:
# numeric addition with strings:
my $sum = '5.45' + '0.01'; # 5.46
If you do strings sorts of things, you get strings:
# string replication with numbers:
my $string = ( 45/2 ) x 4; # "22.522.522.522.5"
Perl mostly figures out what to do and it's mostly right. Another way of saying the same thing is that Perl cares more about the verbs than it does the nouns.
Are you trying to do something and it isn't working?
I have found this to be really useful:
df = pd.DataFrame({'A' : range(0,10) * 2, 'B' : np.random.randint(20,30,20)})
# A ascending, B descending
df.sort(**skw(columns=['A','-B']))
# A descending, B ascending
df.sort(**skw(columns=['-A','+B']))
Note that unlike the standard columns=,ascending=
arguments, here column names and their sort order are in the same place. As a result your code gets a lot easier to read and maintain.
Note the actual call to .sort
is unchanged, skw
(sortkwargs) is just a small helper function that parses the columns and returns the usual columns=
and ascending=
parameters for you. Pass it any other sort kwargs as you usually would. Copy/paste the following code into e.g. your local utils.py
then forget about it and just use it as above.
# utils.py (or anywhere else convenient to import)
def skw(columns=None, **kwargs):
""" get sort kwargs by parsing sort order given in column name """
# set default order as ascending (+)
sort_cols = ['+' + col if col[0] != '-' else col for col in columns]
# get sort kwargs
columns, ascending = zip(*[(col.replace('+', '').replace('-', ''),
False if col[0] == '-' else True)
for col in sort_cols])
kwargs.update(dict(columns=list(columns), ascending=ascending))
return kwargs
The return type of Html.RenderAction
is void
that means it directly renders the responses in View where the return type of Html.Action
is MvcHtmlString
You can catch its render view in controller and modify it by using following method
protected string RenderPartialViewToString(string viewName, object model)
{
if (string.IsNullOrEmpty(viewName))
viewName = ControllerContext.RouteData.GetRequiredString("action");
ViewData.Model = model;
using (StringWriter sw = new StringWriter())
{
ViewEngineResult viewResult = ViewEngines.Engines.FindPartialView(ControllerContext, viewName);
ViewContext viewContext = new ViewContext(ControllerContext, viewResult.View, ViewData, TempData, sw);
viewResult.View.Render(viewContext, sw);
return sw.GetStringBuilder().ToString();
}
}
This will return the Html string of the View.
This is also applicable to Html.Partial
and Html.RenderPartial
One way to achieve this is
>>> pd.DataFrame(np.array([[2, 3, 4]]), columns=['A', 'B', 'C']).append(df, ignore_index=True)
Out[330]:
A B C
0 2 3 4
1 5 6 7
2 7 8 9
Generally, it's easiest to append dataframes, not series. In your case, since you want the new row to be "on top" (with starting id), and there is no function pd.prepend()
, I first create the new dataframe and then append your old one.
ignore_index
will ignore the old ongoing index in your dataframe and ensure that the first row actually starts with index 1
instead of restarting with index 0
.
Typical Disclaimer: Cetero censeo ... appending rows is a quite inefficient operation. If you care about performance and can somehow ensure to first create a dataframe with the correct (longer) index and then just inserting the additional row into the dataframe, you should definitely do that. See:
>>> index = np.array([0, 1, 2])
>>> df2 = pd.DataFrame(columns=['A', 'B', 'C'], index=index)
>>> df2.loc[0:1] = [list(s1), list(s2)]
>>> df2
Out[336]:
A B C
0 5 6 7
1 7 8 9
2 NaN NaN NaN
>>> df2 = pd.DataFrame(columns=['A', 'B', 'C'], index=index)
>>> df2.loc[1:] = [list(s1), list(s2)]
So far, we have what you had as df
:
>>> df2
Out[339]:
A B C
0 NaN NaN NaN
1 5 6 7
2 7 8 9
But now you can easily insert the row as follows. Since the space was preallocated, this is more efficient.
>>> df2.loc[0] = np.array([2, 3, 4])
>>> df2
Out[341]:
A B C
0 2 3 4
1 5 6 7
2 7 8 9
I would assume at the end of the day you want to consume the data in the ArrayNode by iterating it. For that:
Iterator<JsonNode> iterator = datasets.withArray("datasets").elements();
while (iterator.hasNext())
System.out.print(iterator.next().toString() + " ");
or if you're into streams and lambda functions:
import com.google.common.collect.Streams;
Streams.stream(datasets.withArray("datasets").elements())
.forEach( item -> System.out.print(item.toString()) )
the effect that happens when you hit the space bar in a folder of documents, allowing you to preview them in a lightbox fashion
Looks like a classic lightbox plugin is needed. This is my favorite jQuery lightbox plugin: http://colorpowered.com/colorbox/. It's easy to customize, etc.
Here's the code I came up with to remove items selected by a user from a listbox It seems to work ok in a multiselect listbox (selectionmode prop is set to multiextended).:
Private Sub cmdRemoveList_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles cmdRemoveList.Click
Dim knt As Integer = lstwhatever.SelectedIndices.Count
Dim i As Integer
For i = 0 To knt - 1
lstwhatever.Items.RemoveAt(lstwhatever.SelectedIndex)
Next
End Sub
I will try to explain the purpose of looper class as simple as possible. With a normal thread of Java when the run method completes the execution we say the thread has done it's job and thread lives no longer after that. what if we want to execute more tasks throughout our program with that same thread which is not living anymore? Oh there is a problem now right? Yes because we want to execute more tasks but the thread in not alive anymore. It is where the Looper comes in to rescue us. Looper as the name suggests loops. Looper is nothing more than an infinite loop inside your thread. So, it keeps the thread alive for an infinite time until we explicitly calls quit() method. Calling quit() method on the infinitely alive thread will make the condition false in the infinite loop inside the thread thus, infinite loop will exit. so, the thread will die or will no longer be alive. And it's critical to call the quit() method on our Thread to which looper is attached otherwise they will be there in your system just like Zombies. So, for example if we want to create a background thread to do some multiple tasks over it. we will create a simple Java's thread and will use Looper class to prepare a looper and attach the prepared looper with that thread so that our thread can live as longer as we want them because we can always call quit() anytime whenever we want to terminate our thread. So our the looper will keep our thread alive thus we will be able to execute multiple tasks with the same thread and when we are done we will call quit() to terminate the thread. What if we want our Main thread or UI thread to display the results computed by the background thread or non-UI thread on some UI elements? for that purpose there comes in the concept of Handlers; via handlers we can do inter-process communication or say via handlers two threads can communicate with each other. So, the main thread will have an associated Handler and Background thread will communicate with Main Thread via that handler to get the task done of displaying the results computed by it on some UI elements on Main thread. I know I am explaining only theory here but try to understand the concept because understanding the concept in depth is very important. And I am posting a link below which will take you to a small video series about Looper, Handler and HandlerThread and I will highly recommend watching it and all these concepts will get cleared with examples there.

To send an HTTP DELETE with some headers via axios
I've done this:
const deleteUrl = "http//foo.bar.baz";
const httpReqHeaders = {
'Authorization': token,
'Content-Type': 'application/json'
};
// check the structure here: https://github.com/axios/axios#request-config
const axiosConfigObject = {headers: httpReqHeaders};
axios.delete(deleteUrl, axiosConfigObject);
The axios
syntax for different HTTP verbs (GET, POST, PUT, DELETE) is tricky because sometimes the 2nd parameter is supposed to be the HTTP body, some other times (when it might not be needed) you just pass the headers as the 2nd parameter.
However let's say you need to send an HTTP POST request without an HTTP body, then you need to pass undefined
as the 2nd parameter.
Bare in mind that according to the definition of the configuration object (https://github.com/axios/axios#request-config) you can still pass an HTTP body in the HTTP call via the data
field when calling axios.delete
, however for the HTTP DELETE verb it will be ignored.
This confusion between the 2nd parameter being sometimes the HTTP body and some other time the whole config
object for axios
is due to how the HTTP rules have been implemented. Sometimes an HTTP body is not needed for an HTTP call to be considered valid.
By the way guys, (int)Decimal.MaxValue will overflow. You can't get the "int" part of a decimal because the decimal is too friggen big to put in the int box. Just checked... its even too big for a long (Int64).
If you want the bit of a Decimal value to the LEFT of the dot, you need to do this:
Math.Truncate(number)
and return the value as... A DECIMAL or a DOUBLE.
edit: Truncate is definitely the correct function!
In SQL
, the order of the output is not defined unless you specify it in the ORDER BY
clause.
Try this:
SELECT *
FROM one
JOIN two
ON one.one_name = two.one_name
ORDER BY
one.id
You can compare both approaches for the same data:
def myGeneratorList(n):
for i in range(n):
yield i
def myIterableList(n):
ll = n*[None]
for i in range(n):
ll[i] = i
return ll
# Same values
ll1 = myGeneratorList(10)
ll2 = myIterableList(10)
for i1, i2 in zip(ll1, ll2):
print("{} {}".format(i1, i2))
# Generator can only be read once
ll1 = myGeneratorList(10)
ll2 = myIterableList(10)
print("{} {}".format(len(list(ll1)), len(ll2)))
print("{} {}".format(len(list(ll1)), len(ll2)))
# Generator can be read several times if converted into iterable
ll1 = list(myGeneratorList(10))
ll2 = myIterableList(10)
print("{} {}".format(len(list(ll1)), len(ll2)))
print("{} {}".format(len(list(ll1)), len(ll2)))
Besides, if you check the memory footprint, the generator takes much less memory as it doesn't need to store all the values in memory at the same time.
Type-safe means that programmatically, the type of data for a variable, return value, or argument must fit within a certain criteria.
In practice, this means that 7 (an integer type) is different from "7" (a quoted character of string type).
PHP, Javascript and other dynamic scripting languages are usually weakly-typed, in that they will convert a (string) "7" to an (integer) 7 if you try to add "7" + 3, although sometimes you have to do this explicitly (and Javascript uses the "+" character for concatenation).
C/C++/Java will not understand that, or will concatenate the result into "73" instead. Type-safety prevents these types of bugs in code by making the type requirement explicit.
Type-safety is very useful. The solution to the above "7" + 3 would be to type cast (int) "7" + 3 (equals 10).
i resolve this problem in this way, later i will improve the code

URL url = new URL(toEscape);
URI uri = new URI(url.getProtocol(), url.getUserInfo(), url.getHost(), url.getPort(), url.getPath(), url.getQuery(), url.getRef());

Object.http://en.wikipedia.org/wiki/Byte_order_mark
The byte order mark (BOM) is a Unicode character used to signal the endianness (byte order) of a text file or stream. Its code point is U+FEFF. BOM use is optional, and, if used, should appear at the start of the text stream. Beyond its specific use as a byte-order indicator, the BOM character may also indicate which of the several Unicode representations the text is encoded in.
The BOM is a funky-looking character that you sometimes find at the start of unicode streams, giving a clue what the encoding is. It's usually handles invisibly by the string-handling stuff in Java, so you must have confused it somehow, but without seeing your code, it's hard to see where.
You might be able to fix it trivially by manually stripping the BOM from the string before feeding it to javac
. It probably qualifies as whitespace, so try calling trim()
on the input String, and feeding the output of that to javac
.
Please try below stored procedure. I have already verified. I am getting proper result but without using groupby

Let's say you have the following in your DB:
table enums
-----------------
| id | name |
-----------------
| 0 | MyEnum |
| 1 | YourEnum |
-----------------
table enum_values
----------------------------------
| id | enums_id | value | key |
----------------------------------
| 0 | 0 | 0 | Apple |
| 1 | 0 | 1 | Banana |
| 2 | 0 | 2 | Pear |
| 3 | 0 | 3 | Cherry |
| 4 | 1 | 0 | Red |
| 5 | 1 | 1 | Green |
| 6 | 1 | 2 | Yellow |
----------------------------------
Construct a select to get the values you need:
select * from enums e inner join enum_values ev on ev.enums_id=e.id where e.id=0
Construct the source code for the enum and you'll get something like:
String enumSourceCode = "enum " + enumName + "{" + enumKey1 + "=" enumValue1 + "," + enumKey2 + ... + "}";
(obviously this is constructed in a loop of some kind.)
Then comes the fun part, Compiling your enum and using it:
CodeDomProvider provider = CodeDomProvider.CreateProvider("CSharp");
CompilerParameters cs = new CompilerParameters();
cp.GenerateInMemory = True;
CompilerResult result = provider.CompileAssemblyFromSource(cp, enumSourceCode);
Type enumType = result.CompiledAssembly.GetType(enumName);
Now you have the type compiled and ready for use.
To get a enum value stored in the DB you can use:
[Enum].Parse(enumType, value);
where value can be either the integer value (0, 1, etc.) or the enum text/key (Apple, Banana, etc.)
For anyone landing here who is trying to upgrade from MVC 4 to MVC5, I was able to resolve this issue by following the instructions at http://www.asp.net/mvc/tutorials/mvc-5/how-to-upgrade-an-aspnet-mvc-4-and-web-api-project-to-aspnet-mvc-5-and-web-api-2.
I also had to install the "Microsoft.AspNet.WebApi.WebHost" package from nuget. But that's it.
Oh, and I had to create this appSetting: <add key="owin:AutomaticAppStartup" value="false" />
:)
Using class members to give default values works very well just so long as you are careful only to do it with immutable values. If you try to do it with a list or a dict that would be pretty deadly. It also works where the instance attribute is a reference to a class just so long as the default value is None.
I've seen this technique used very successfully in repoze which is a framework that runs on top of Zope. The advantage here is not just that when your class is persisted to the database only the non-default attributes need to be saved, but also when you need to add a new field into the schema all the existing objects see the new field with its default value without any need to actually change the stored data.
I find it also works well in more general coding, but it's a style thing. Use whatever you are happiest with.
With numpy, you can pass a slice for each component of the index - so, your x[0:2,0:2]
example above works.
If you just want to evenly skip columns or rows, you can pass slices with three components (i.e. start, stop, step).
Again, for your example above:
>>> x[1:4:2, 1:4:2]
array([[ 5, 7],
[13, 15]])
Which is basically: slice in the first dimension, with start at index 1, stop when index is equal or greater than 4, and add 2 to the index in each pass. The same for the second dimension. Again: this only works for constant steps.
The syntax you got to do something quite different internally - what x[[1,3]][:,[1,3]]
actually does is create a new array including only rows 1 and 3 from the original array (done with the x[[1,3]]
part), and then re-slice that - creating a third array - including only columns 1 and 3 of the previous array.
<p>
@Html.ActionLink("Create New", "Create")
</p>
@using (Html.BeginForm("Index", "Company", FormMethod.Get))
{
<p>
Find by Name: @Html.TextBox("SearchString", ViewBag.CurrentFilter as string)
<input type="submit" value="Search" />
<input type="button" value="Clear" onclick="location.href='@Url.Action("Index","Company")'"/>
</p>
}
In the above example you can see that If I specifically need a button to do some action, I have to do it with @Url.Action whereas if I just want a link I will use @Html.ActionLink. The point is when you have to use some element(HTML) with action url is used.
If you luckily had the same files opened on another editor (eg. Sublime Text) try a ctrl-z on those. It just saved me..
For "Xamarin Android":
FindViewById<Button>(Resource.Id.Button1).Visibility = ViewStates.Gone;
FWIW, in Boostrap 4.4, you can add .text-wrap
style to things like buttons:
<a href="#" class="btn btn-primary text-wrap">Lorem ipsum dolor sit amet, consectetur adipiscing elit.</a>

I have one other way to do this same thing works perfectly. so the idea behind to show all markers on the screen we need a center lat long and zoom level. here is the function which will give you both and need all marker's Latlng objects as input.
public Pair<LatLng, Integer> getCenterWithZoomLevel(LatLng... l) {
float max = 0;
if (l == null || l.length == 0) {
return null;
}
LatLngBounds.Builder b = new LatLngBounds.Builder();
for (int count = 0; count < l.length; count++) {
if (l[count] == null) {
continue;
}
b.include(l[count]);
}
LatLng center = b.build().getCenter();
float distance = 0;
for (int count = 0; count < l.length; count++) {
if (l[count] == null) {
continue;
}
distance = distance(center, l[count]);
if (distance > max) {
max = distance;
}
}
double scale = max / 1000;
int zoom = ((int) (16 - Math.log(scale) / Math.log(2)));
return new Pair<LatLng, Integer>(center, zoom);
}
This function return Pair object which you can use like
Pair pair = getCenterWithZoomLevel(l1,l2,l3..); mGoogleMap.moveCamera(CameraUpdateFactory.newLatLngZoom(pair.first, pair.second));
you can instead of using padding to keep away your markers from screen boundaries, you can adjust zoom by -1.
This should work (untested, based on JavaDoc):
DecimalFormat formatter = (DecimalFormat) NumberFormat.getInstance(Locale.US);
DecimalFormatSymbols symbols = formatter.getDecimalFormatSymbols();
symbols.setGroupingSeparator(' ');
formatter.setDecimalFormatSymbols(symbols);
System.out.println(formatter.format(bd.longValue()));
According to the JavaDoc, the cast in the first line should be save for most locales.
In SQL you need to use GETDATE()
:
UPDATE table SET date = GETDATE();
There is no NOW()
function.
To answer your question:
In a large table, since the function is evaluated for each row, you will end up getting different values for the updated field.
So, if your requirement is to set it all to the same date I would do something like this (untested):
DECLARE @currDate DATETIME;
SET @currDate = GETDATE();
UPDATE table SET date = @currDate;
You will have to change some of your data types but the basics of what you just posted could be converted to something similar to this given the data types I used may not be accurate.
Dim DateToday As String: DateToday = Format(Date, "yyyy/MM/dd")
Dim Computers As New Collection
Dim disabledList As New Collection
Dim compArray(1 To 1) As String
'Assign data to first item in array
compArray(1) = "asdf"
'Format = Item, Key
Computers.Add "ErrorState", "Computer Name"
'Prints "ErrorState"
Debug.Print Computers("Computer Name")
Collections cannot be sorted so if you need to sort data you will probably want to use an array.

var toDelete = [];

toDelete.push(i);
}
}
for (var i = 0; i < toDelete.length; i++) {
segments.splice(i, 1);
}

I wrote a python script that parses a markdown file and outputs a table of contents as a markdown list: md-to-toc
Unlike other scripts I've found, md-to-toc correctly supports duplicate titles. It also doesn't require an internet connection, so it works on any md file, not just those available from a public repo.
list_of_ints = [int(i) for i in str(ISBN)]
Will give you a ordered list of ints. Of course, given duck typing, you might as well work with str(ISBN).
Edit: As mentioned in the comments, this list isn't sorted in the sense of being ascending or descending, but it does have a defined order (sets, dictionaries, etc in python in theory don't, although in practice the order tends to be fairly reliable). If you want to sort it:
list_of_ints.sort()
is your friend. Note that sort() sorts in place (as in, actually changes the order of the existing list) and doesn't return a new list.
I went ahead and made a function for you:
Object.prototype.getValueByIndex = function (index) {
/*
Object.getOwnPropertyNames() takes in a parameter of the object,
and returns an array of all the properties.
In this case it would return: ["something","evenmore"].
So, this[Object.getOwnPropertyNames(this)[index]]; is really just the same thing as:
this[propertyName]
*/
return this[Object.getOwnPropertyNames(this)[index]];
};
let obj = {
'something' : 'awesome',
'evenmore' : 'crazy'
};
console.log(obj.getValueByIndex(0)); // Expected output: "awesome"

The OP doesn't mention if this is DB2/400 being discussed, but I found that the only way I could get the table structure including the column name descriptions was to use DSPFFD.
DSPFFD FILE(TBNAME) OUTPUT(*OUTFILE) OUTFILE(SOMELIB/TBDESC)
This puts the description of TBNAME in a table called TBDESC in the SOMELIB library. You can then query that with:
select * from SOMELIB/TBDESC
You can always use iptables to delete the rules. If you have a lot of rules, just output them using the following command.
iptables-save > myfile
vi
to edit them from the commend line. Just use the "dd" to delete the lines you no longer want.
iptables-restore < myfile and you're good to go.
REMEMBER THAT IF YOU DON'T CONFIGURE YOUR OS TO SAVE THE RULES TO A FILE AND THEN LOAD THE FILE DURING THE BOOT THAT YOUR RULES WILL BE LOST.
JAVA_OPTS
is environment variable used by tomcat in its startup/shutdown script to configure params.
You can set it in linux by
export JAVA_OPTS="-Djava.awt.headless=true"
I don't have PHP experience, but I have an understanding of the Python standard library.
For your purposes, Python has several methods:
logging module;
Object serialization module which is called pickle. You may write your own wrapper of the pickle module.
If your using var_dump
for testing, Python has its own doctest and unittest modules. It's very simple and fast for design.

mailx might help as well. From the mailx man page:
-a file
Attach the given file to the message.
Pretty easy, right?
Use this is working fine.
$dir = '/Folder/';
$zip = new ZipArchive();
$res = $zip->open(trim($dir, "/") . '.zip', ZipArchive::CREATE | ZipArchive::OVERWRITE);
if ($res === TRUE) {
foreach (glob($dir . '*') as $file) {
$zip->addFile($file, basename($file));
}
$zip->close();
} else {
echo 'Failed to create to zip. Error: ' . $res;
}
The one above is ok...but you will encounter data corruption when you send stuff over SMTP (if you need to). I've altered to something else that will help to correctly send byte for byte: '
using System;
using System.IO;
private static byte[] ReadFully(string input)
{
FileStream sourceFile = new FileStream(input, FileMode.Open); //Open streamer
BinaryReader binReader = new BinaryReader(sourceFile);
byte[] output = new byte[sourceFile.Length]; //create byte array of size file
for (long i = 0; i < sourceFile.Length; i++)
output[i] = binReader.ReadByte(); //read until done
sourceFile.Close(); //dispose streamer
binReader.Close(); //dispose reader
return output;
}'
I will show you a whole example of servlet & how do ajax call.
Here, we are going to create the simple example to create the login form using servlet.
index.html
<form>
Name:<input type="text" name="username"/><br/><br/>
Password:<input type="password" name="userpass"/><br/><br/>
<input type="button" value="login"/>
</form>
Here is ajax Sample
$.ajax
({
type: "POST",
data: 'LoginServlet='+name+'&name='+type+'&pass='+password,
url: url,
success:function(content)
{
$('#center').html(content);
}
});
LoginServlet Servlet Code :-
package abc.servlet;
import java.io.File;
public class AuthenticationServlet extends HttpServlet {
private static final long serialVersionUID = 1L;
protected void doGet(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException
{
doPost(request, response);
}
protected void doPost(HttpServletRequest request,
HttpServletResponse response) throws ServletException, IOException {
try{
HttpSession session = request.getSession();
String username = request.getParameter("name");
String password = request.getParameter("pass");
/// Your Code
out.println("sucess / failer")
} catch (Exception ex) {
// System.err.println("Initial SessionFactory creation failed.");
ex.printStackTrace();
System.exit(0);
}
}
}
This may not have been the OP's problem, but I had the same problem and solved it by flushing then disabling Supercache on my cpanel. Perhaps some other newbies like myself won't know that many hosting providers cache CSS and some other static files, and these cached old versions of CSS files will persist in the cloud for hours after you edit the file on your server. If your site serves up old versions of CSS files after you edit them, and you're certain you've cleared your browser cache, and you don't know whether your host is caching stuff, check that first before you try any other more complicated suggestions.
Short answer: Don't do it.
Redesign your app so that it can run in both portrait and landscape mode. There is no such thing as a UI that can't be designed to work in both portrait and landscape; only lazy or unimaginative developers.
The reason why is rather simple. You want your app to be usable by as wide an audience as possible on as many different devices as possible. By forcing a particular screen orientation, you prevent your app from running (usably) on devices that don't support that orientation and you frustrate and alienate potential customers who prefer a different orientation.
Example: You design your app to force portrait mode. A customer downloads the app on a 2-in-1 device which they use predominantly in landscape mode.
Consequence 1: Your app is unusable, or your customer is forced to undock their device, rotate it, and use it in an orientation that is not familiar or comfortable for them.
Consequence 2: The customer gets frustrated by your app's non-intuitive design and finds an alternative or ditches the app entirely.
I'm fighting with this with an app right now and as a consumer and a developer, I hate it. As useful as the app is, as fantastic as the features are that it offers, I absolutely hate the app because it forces me to use an orientation that is counter to every other way that I use my device.
You don't want your customers to hate your app.
I know this doesn't directly answer the question, so I want to explain it in a little more detail for those who are curious.
There is a tendency for developers to be really good at writing code and really terrible at design. This question, though it sounds like a code question and the asker certainly feels like it's a code question, is really a design question.
The question really is "Should I lock the screen orientation in my app?" The asker chose to design the UI to function and look good only in portrait mode. I suspect it was to save development time or because the app's workflow is particularly conducive to a portrait layout (common for mobile games). But those reasons neglect all the real important factors that motivate proper design.
Customer engagement - you want your customers to feel pulled into your app, not pushed out of it. The app should transition smoothly from whatever your customer was doing prior to opening your app. (This is the reason most platforms have consistent design principles, so most apps look more or less alike though they don't have to.)
Customer response - you want your customers to react positively to your app. They should enjoy using it. Even if it's a payroll app for work, it should be a pleasure for them to open it and clock in. The app should save your customers time and reduce frustration over alternatives. (Apps that annoy users build resentment against your app which grows into resentment against your brand.)
Customer conversion - you want your customers to be able to quickly and easily move from browsing to interacting. This is the ultimate goal of any app, to convert impressions into revenue. (Apps that don't generate revenue are a waste of your time to build, from a business perspective.)
A poorly designed UI reduces customer engagement and response which ultimately results in lower revenue. In a mobile-centric world (and particularly on the subject of portrait/landscape display modes), this explains why responsive web design is such a big deal. Walmart Canada introduced responsive design on their website in November 2013 and saw a 20% increase in customer conversion. O'Neill Clothing implemented responsive web design and revenue from customers using iOS devices increased 101.25%, and 591.42% from customers using Android devices.
There is also a tendency for developers to focus intently on implementing a particular solution (such as locking display orientation), and most of the developers on this site will be all too glad to help implement that solution, without questioning whether that is even the best solution to the problem.
Locking your screen orientation is the UI design equivalent of implementing a do-while loop. Are you really sure you want to do it that way, or is there a better alternative?
Don't force your app into a single display mode. Invest the extra time and effort to make it responsive.
The error comes when you try to call sum(x)
and x
is a factor.
What that means is that one of your columns, though they look like numbers are actually factors (what you are seeing is the text representation)
simple fix, convert to numeric. However, it needs an intermeidate step of converting to character first. Use the following:
family[, 1] <- as.numeric(as.character( family[, 1] ))
family[, 3] <- as.numeric(as.character( family[, 3] ))
For a detailed explanation of why the intermediate as.character
step is needed, take a look at this question: How to convert a factor to integer\numeric without loss of information?
You're close, you just need to delete the file before trying to over-write it.
dim infolder: set infolder = fso.GetFolder(IN_PATH)
dim file: for each file in infolder.Files
dim name: name = file.name
dim parts: parts = split(name, ".")
if UBound(parts) = 2 then
' file name like a.c.pdf
dim newname: newname = parts(0) & "." & parts(2)
dim newpath: newpath = fso.BuildPath(OUT_PATH, newname)
' warning:
' if we have source files C:\IN_PATH\ABC.01.PDF, C:\IN_PATH\ABC.02.PDF, ...
' only one of them will be saved as D:\OUT_PATH\ABC.PDF
if fso.FileExists(newpath) then
fso.DeleteFile newpath
end if
file.Move newpath
end if
next
I would do something like this:
$.each(temp,function(key, value)
{
$select.append('<option value=' + key + '>' + value + '</option>');
});
JSON structure would be appreciated. At first you can experiment with find('element')
- it depends on JSON.
Making these 2 communicate
=IF(OR(AND(MID(K27,6,1)="N",(MID(K27,6,1)="C"),(MID(K27,6,1)="H"),(MID(K27,6,1)="I"),(MID(K27,6,1)="B"),(MID(K27,6,1)="F"),(MID(K27,6,1)="L"),(MID(K27,6,1)="M"),(MID(K27,6,1)="P"),(MID(K27,6,1)="R"),(MID(K27,6,1)="P"),ISTEXT(G27)="61"),AND(RIGHT(K27,2)=G27)),"Good","Review")
=IF(AND(RIGHT(K27,2)=G27),"Good","Review")
To take first 5 elements better use expression like this one:
var firstFiveArrivals = myList.Where([EXPRESSION]).Take(5);
or
var firstFiveArrivals = myList.Where([EXPRESSION]).Take(5).OrderBy([ORDER EXPR]);
It will be faster than orderBy variant, because LINQ engine will not scan trough all list due to delayed execution, and will not sort all array.
class MyList : IEnumerable<int>
{
int maxCount = 0;
public int RequestCount
{
get;
private set;
}
public MyList(int maxCount)
{
this.maxCount = maxCount;
}
public void Reset()
{
