I think that it is better (for my expirience) to use: :first-of-type
, :nth-of-type()
, :last-of-type
. It can be done whit a little changing of rules, but I was able to do much more than whit *-of-type
, than *-child
selectors.

Happy designing .. ! :)
I had this same issue. The package name was wrong in two of the following three files. I manually updated the package name and everything started working again.
gen/com/example/app/BuildConfig.java
gen/com/example/app/Manifest.java
gen/com/example/app/R.java
I'm not sure what caused them to change as I've never modified these files before.
Just change convert datetime to time that should do the trick:
SELECT timeEvent
FROM tbEvents
WHERE convert(time, startHour) >= convert(time, @startHour)
If you'd checked the results of stream.Read
, you'd have seen that it hadn't read anything - because you haven't rewound the stream. (You could do this with stream.Position = 0;
.) However, it's easier to just call ToArray
:
settingsString = LocalEncoding.GetString(stream.ToArray());
(You'll need to change the type of stream
from Stream
to MemoryStream
, but that's okay as it's in the same method where you create it.)
Alternatively - and even more simply - just use StringWriter
instead of StreamWriter
. You'll need to create a subclass if you want to use UTF-8 instead of UTF-16, but that's pretty easy. See this answer for an example.
I'm concerned by the way you're just catching Exception
and assuming that it means something harmless, by the way - without even logging anything. Note that using
statements are generally cleaner than writing explicit finally
blocks.
Sign-off is a requirement for getting patches into the Linux kernel and a few other projects, but most projects don't actually use it.
It was introduced in the wake of the SCO lawsuit, (and other accusations of copyright infringement from SCO, most of which they never actually took to court), as a Developers Certificate of Origin. It is used to say that you certify that you have created the patch in question, or that you certify that to the best of your knowledge, it was created under an appropriate open-source license, or that it has been provided to you by someone else under those terms. This can help establish a chain of people who take responsibility for the copyright status of the code in question, to help ensure that copyrighted code not released under an appropriate free software (open source) license is not included in the kernel.
If there is polymorphism such as checking SQLRecoverableException vs SQLException, it can be done like that.
try {
// sth may throw exception
....
} catch (Exception e) {
if(SQLException.class.isAssignableFrom(e.getCause().getClass()))
{
// do sth
System.out.println("SQLException occurs!");
}
}
Simply say,
ChildClass child= new ChildClass();
if(ParentClass.class.isAssignableFrom(child.getClass()))
{
// do sth
...
}
Try Winhttrack
...offline browser utility.
It allows you to download a World Wide Web site from the Internet to a local directory, building recursively all directories, getting HTML, images, and other files from the server to your computer. HTTrack arranges the original site's relative link-structure. Simply open a page of the "mirrored" website in your browser, and you can browse the site from link to link, as if you were viewing it online. HTTrack can also update an existing mirrored site, and resume interrupted downloads. HTTrack is fully configurable, and has an integrated help system.
WinHTTrack is the Windows 2000/XP/Vista/Seven release of HTTrack, and WebHTTrack the Linux/Unix/BSD release...
You can do it this way:
(Edit: Considering that you're waiting for a response json
with dataType: 'json'
)
.NET
public JsonResult Edit(EditPostViewModel data)
{
if(ModelState.IsValid)
{
// Save
return Json(new { Ok = true } );
}
return Json(new { Ok = false } );
}
JS:
success: function (data) {
if (data.Ok) {
alert('success');
}
else {
alert('problem');
}
},
If you need I can also explain how to do it by returning a error 500, and get the error in the event error (ajax). But in your case this may be an option
This is code I used in Windows. It works.
for item in COOKIES.split(';'):
name,value = item.split('=', 1)
name=name.replace(' ', '').replace('\r', '').replace('\n', '')
value = value.replace(' ', '').replace('\r', '').replace('\n', '')
cookie_dict={
'name':name,
'value':value,
"domain": "", # Google Chrome
"expires": "",
'path': '/',
'httpOnly': False,
'HostOnly': False,
'Secure': False
}
self.driver_.add_cookie(cookie_dict)
Like Pekka said, it should work this way. I can't reproduce the problem with this self-contained example:
<?php
$pdo = new PDO('mysql:host=localhost;dbname=test;charset=utf8', 'localonly', 'localonly');
$pdo->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
$pdo->setAttribute(PDO::ATTR_EMULATE_PREPARES, false);
$pdo->exec('
CREATE TEMPORARY TABLE soFoo (
id int auto_increment,
first int,
last int,
whenadded DATETIME,
primary key(id)
)
');
$pdo->exec('INSERT INTO soFoo (first,last,whenadded) VALUES (0,1,Now())');
$pdo->exec('INSERT INTO soFoo (first,last,whenadded) VALUES (0,2,Now())');
$pdo->exec('INSERT INTO soFoo (first,last,whenadded) VALUES (0,3,Now())');
foreach( $pdo->query('SELECT * FROM soFoo', PDO::FETCH_ASSOC) as $row ) {
echo join(' | ', $row), "\n";
}
Which (currently) prints
1 | 0 | 1 | 2012-03-23 16:00:18
2 | 0 | 2 | 2012-03-23 16:00:18
3 | 0 | 3 | 2012-03-23 16:00:18
And here's (almost) the same script using a TIMESTAMP field and DEFAULT CURRENT_TIMESTAMP:
<?php
$pdo = new PDO('mysql:host=localhost;dbname=test;charset=utf8', 'localonly', 'localonly');
$pdo->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
$pdo->setAttribute(PDO::ATTR_EMULATE_PREPARES, false);
$pdo->exec('
CREATE TEMPORARY TABLE soFoo (
id int auto_increment,
first int,
last int,
whenadded TIMESTAMP DEFAULT CURRENT_TIMESTAMP,
primary key(id)
)
');
$pdo->exec('INSERT INTO soFoo (first,last) VALUES (0,1)');
$pdo->exec('INSERT INTO soFoo (first,last) VALUES (0,2)');
sleep(1);
$pdo->exec('INSERT INTO soFoo (first,last) VALUES (0,3)');
foreach( $pdo->query('SELECT * FROM soFoo', PDO::FETCH_ASSOC) as $row ) {
echo join(' | ', $row), "\n";
}
Conveniently, the timestamp is converted to the same datetime string representation as in the first example - at least with my PHP/PDO/mysqlnd version.
It looks like you're using python 3.x. In python3, filter
, map
, zip
, etc return an object which is iterable, but not a list. In other words,
filter(func,data) #python 2.x
is equivalent to:
list(filter(func,data)) #python 3.x
I think it was changed because you (often) want to do the filtering in a lazy sense -- You don't need to consume all of the memory to create a list up front, as long as the iterator returns the same thing a list would during iteration.
If you're familiar with list comprehensions and generator expressions, the above filter is now (almost) equivalent to the following in python3.x:
( x for x in data if func(x) )
As opposed to:
[ x for x in data if func(x) ]
in python 2.x
public class DogAgeComparator implements Comparator<Dog> {
public int compare(Dog o1, Dog o2) {
return Integer.compare(o1.getAge(), o2.getId());

}
Our example project has two build targets: HelloWorld.app and Helper.app. We make a component package for each and combine them into a product archive.
A component package contains payload to be installed by the OS X Installer. Although a component package can be installed on its own, it is typically incorporated into a product archive.
After a successful "Build and Archive" open $BUILT_PRODUCTS_DIR in the Terminal.
$ cd ~/Library/Developer/Xcode/DerivedData/.../InstallationBuildProductsLocation
$ pkgbuild --analyze --root ./HelloWorld.app HelloWorldAppComponents.plist
$ pkgbuild --analyze --root ./Helper.app HelperAppComponents.plist
This give us the component-plist, you find the value description in the "Component Property List" section. pkgbuild -root generates the component packages, if you don't need to change any of the default properties you can omit the --component-plist parameter in the following command.
productbuild --synthesize results in a Distribution Definition.
$ pkgbuild --root ./HelloWorld.app \
--component-plist HelloWorldAppComponents.plist \
HelloWorld.pkg
$ pkgbuild --root ./Helper.app \
--component-plist HelperAppComponents.plist \
Helper.pkg
$ productbuild --synthesize \
--package HelloWorld.pkg --package Helper.pkg \
Distribution.xml
In the Distribution.xml you can change things like title, background, welcome, readme, license, and so on. You turn your component packages and distribution definition with this command into a product archive:
$ productbuild --distribution ./Distribution.xml \
--package-path . \
./Installer.pkg
I recommend to take a look at iTunes Installers Distribution.xml to see what is possible. You can extract "Install iTunes.pkg" with:
$ pkgutil --expand "Install iTunes.pkg" "Install iTunes"
I usually have a folder named Package in my project which includes things like Distribution.xml, component-plists, resources and scripts.
Add a Run Script Build Phase named "Generate Package", which is set to Run script only when installing:
VERSION=$(defaults read "${BUILT_PRODUCTS_DIR}/${FULL_PRODUCT_NAME}/Contents/Info" CFBundleVersion)
PACKAGE_NAME=`echo "$PRODUCT_NAME" | sed "s/ /_/g"`
TMP1_ARCHIVE="${BUILT_PRODUCTS_DIR}/$PACKAGE_NAME-tmp1.pkg"
TMP2_ARCHIVE="${BUILT_PRODUCTS_DIR}/$PACKAGE_NAME-tmp2"
TMP3_ARCHIVE="${BUILT_PRODUCTS_DIR}/$PACKAGE_NAME-tmp3.pkg"
ARCHIVE_FILENAME="${BUILT_PRODUCTS_DIR}/${PACKAGE_NAME}.pkg"
pkgbuild --root "${INSTALL_ROOT}" \
--component-plist "./Package/HelloWorldAppComponents.plist" \
--scripts "./Package/Scripts" \
--identifier "com.test.pkg.HelloWorld" \
--version "$VERSION" \
--install-location "/" \
"${BUILT_PRODUCTS_DIR}/HelloWorld.pkg"
pkgbuild --root "${BUILT_PRODUCTS_DIR}/Helper.app" \
--component-plist "./Package/HelperAppComponents.plist" \
--identifier "com.test.pkg.Helper" \
--version "$VERSION" \
--install-location "/" \
"${BUILT_PRODUCTS_DIR}/Helper.pkg"
productbuild --distribution "./Package/Distribution.xml" \
--package-path "${BUILT_PRODUCTS_DIR}" \
--resources "./Package/Resources" \
"${TMP1_ARCHIVE}"
pkgutil --expand "${TMP1_ARCHIVE}" "${TMP2_ARCHIVE}"
# Patches and Workarounds
pkgutil --flatten "${TMP2_ARCHIVE}" "${TMP3_ARCHIVE}"
productsign --sign "Developer ID Installer: John Doe" \
"${TMP3_ARCHIVE}" "${ARCHIVE_FILENAME}"
If you don't have to change the package after it's generated with productbuild you could get rid of the pkgutil --expand
and pkgutil --flatten
steps. Also you could use the --sign paramenter on productbuild instead of running productsign.
Packages are signed with the Developer ID Installer certificate which you can download from Developer Certificate Utility.
They signing is done with the --sign "Developer ID Installer: John Doe"
parameter of pkgbuild, productbuild or productsign.
Note that if you are going to create a signed product archive using productbuild, there is no reason to sign the component packages.
To copy something into the Xcode Archive we can't use the Run Script Build Phase. For this we need to use a Scheme Action.
Edit Scheme and expand Archive. Then click post-actions and add a New Run Script Action:
In Xcode 6:
#!/bin/bash
PACKAGES="${ARCHIVE_PATH}/Packages"
PACKAGE_NAME=`echo "$PRODUCT_NAME" | sed "s/ /_/g"`
ARCHIVE_FILENAME="$PACKAGE_NAME.pkg"
PKG="${OBJROOT}/../BuildProductsPath/${CONFIGURATION}/${ARCHIVE_FILENAME}"
if [ -f "${PKG}" ]; then
mkdir "${PACKAGES}"
cp -r "${PKG}" "${PACKAGES}"
fi
In Xcode 5, use this value for PKG
instead:
PKG="${OBJROOT}/ArchiveIntermediates/${TARGET_NAME}/BuildProductsPath/${CONFIGURATION}/${ARCHIVE_FILENAME}"
In case your version control doesn't store Xcode Scheme information I suggest to add this as shell script to your project so you can simple restore the action by dragging the script from the workspace into the post-action.
There are two different kinds of scripting: JavaScript in Distribution Definition Files and Shell Scripts.
The best documentation about Shell Scripts I found in WhiteBox - PackageMaker How-to, but read this with caution because it refers to the old package format.
In order for the package to run as arm64, the Distribution file has to specify in its hostArchitectures
section that it supports arm64
in addition to x86_64
:
<options hostArchitectures="arm64,x86_64" />
Destination Select Pane
The user is presented with the destination select option with only a single choice - "Install for all users of this computer". The option appears visually selected, but the user needs to click on it in order to proceed with the installation, causing some confusion.
Apples Documentation recommends to use <domains enable_anywhere ... />
but this triggers the new more buggy Destination Select Pane which Apple doesn't use in any of their Packages.
Using the deprecate <options rootVolumeOnly="true" />
give you the old Destination Select Pane.
You want to install items into the current user’s home folder.
Short answer: DO NOT TRY IT!
Long answer: REALLY; DO NOT TRY IT! Read Installer Problems and Solutions. You know what I did even after reading this? I was stupid enough to try it. Telling myself I'm sure that they fixed the issues in 10.7 or 10.8.
First of all I saw from time to time the above mentioned Destination Select Pane Bug. That should have stopped me, but I ignored it. If you don't want to spend the week after you released your software answering support e-mails that they have to click once the nice blue selection DO NOT use this.
You are now thinking that your users are smart enough to figure the panel out, aren't you? Well here is another thing about home folder installation, THEY DON'T WORK!
I tested it for two weeks on around 10 different machines with different OS versions and what not, and it never failed. So I shipped it. Within an hour of the release I heart back from users who just couldn't install it. The logs hinted to permission issues you are not gonna be able to fix.
So let's repeat it one more time: We do not use the Installer for home folder installations!
RTFD for Welcome, Read-me, License and Conclusion is not accepted by productbuild
.
Installer supported since the beginning RTFD files to make pretty Welcome screens with images, but productbuild doesn't accept them.
Workarounds:
Use a dummy rtf file and replace it in the package by after productbuild
is done.
Note: You can also have Retina images inside the RTFD file. Use multi-image tiff files for this: tiffutil -cat Welcome.tif Welcome_2x.tif -out FinalWelcome.tif
. More details.
Starting an application when the installation is done with a BundlePostInstallScriptPath script:
#!/bin/bash
LOGGED_IN_USER_ID=`id -u "${USER}"`
if [ "${COMMAND_LINE_INSTALL}" = "" ]
then
/bin/launchctl asuser "${LOGGED_IN_USER_ID}" /usr/bin/open -g PATH_OR_BUNDLE_ID
fi
exit 0
It is important to run the app as logged in user, not as the installer user. This is done with launchctl asuser uid path. Also we only run it when it is not a command line installation, done with installer tool or Apple Remote Desktop.
You have to catch the error just as you're already doing for your save()
call and since you're handling multiple errors here, you can try
multiple calls sequentially in a single do-catch block, like so:
func deleteAccountDetail() {
let entityDescription = NSEntityDescription.entityForName("AccountDetail", inManagedObjectContext: Context!)
let request = NSFetchRequest()
request.entity = entityDescription
do {
let fetchedEntities = try self.Context!.executeFetchRequest(request) as! [AccountDetail]
for entity in fetchedEntities {
self.Context!.deleteObject(entity)
}
try self.Context!.save()
} catch {
print(error)
}
}
Or as @bames53 pointed out in the comments below, it is often better practice not to catch the error where it was thrown. You can mark the method as throws
then try
to call the method. For example:
func deleteAccountDetail() throws {
let entityDescription = NSEntityDescription.entityForName("AccountDetail", inManagedObjectContext: Context!)
let request = NSFetchRequest()
request.entity = entityDescription
let fetchedEntities = try Context.executeFetchRequest(request) as! [AccountDetail]
for entity in fetchedEntities {
self.Context!.deleteObject(entity)
}
try self.Context!.save()
}
If you are still interested in a javascript api to select both date and time data, have a look at these projects which are forks of bootstrap datepicker:
The first fork is a big refactor on the parsing/formatting codebase and besides providing all views to select date/time using mouse/touch, it also has a mask option (by default) which lets the user to quickly type the date/time based on a pre-specified format.
MVC
For an MVC project make the following changes (WebForms and Dot Net Core answer down below):
public static class WebApiConfig
{
public static string UrlPrefix { get { return "api"; } }
public static string UrlPrefixRelative { get { return "~/api"; } }
public static void Register(HttpConfiguration config)
{
config.Routes.MapHttpRoute(
name: "DefaultApi",
routeTemplate: WebApiConfig.UrlPrefix + "/{controller}/{id}",
defaults: new { id = RouteParameter.Optional }
);
}
}
public class MvcApplication : System.Web.HttpApplication
{
...
protected void Application_PostAuthorizeRequest()
{
if (IsWebApiRequest())
{
HttpContext.Current.SetSessionStateBehavior(SessionStateBehavior.Required);
}
}
private bool IsWebApiRequest()
{
return HttpContext.Current.Request.AppRelativeCurrentExecutionFilePath.StartsWith(WebApiConfig.UrlPrefixRelative);
}
}
This solution has the added bonus that we can fetch the base URL in javascript for making the AJAX calls:
<body>
@RenderBody()
<script type="text/javascript">
var apiBaseUrl = '@Url.Content(ProjectNameSpace.WebApiConfig.UrlPrefixRelative)';
</script>
@RenderSection("scripts", required: false)
and then within our Javascript files/code we can make our webapi calls that can access the session:
$.getJSON(apiBaseUrl + '/MyApi')
.done(function (data) {
alert('session data received: ' + data.whatever);
})
);
WebForms
Do the above but change the WebApiConfig.Register function to take a RouteCollection instead:
public static void Register(RouteCollection routes)
{
routes.MapHttpRoute(
name: "DefaultApi",
routeTemplate: WebApiConfig.UrlPrefix + "/{controller}/{id}",
defaults: new { id = RouteParameter.Optional }
);
}
And then call the following in Application_Start:
WebApiConfig.Register(RouteTable.Routes);
Dot Net Core
Add the Microsoft.AspNetCore.Session NuGet package and then make the following code changes:
Call the AddDistributedMemoryCache and AddSession methods on the services object within the ConfigureServices function:
public void ConfigureServices(IServiceCollection services)
{
services.AddMvc();
...
services.AddDistributedMemoryCache();
services.AddSession();
and in the Configure function add a call to UseSession:
public void Configure(IApplicationBuilder app, IHostingEnvironment env,
ILoggerFactory loggerFactory)
{
app.UseSession();
app.UseMvc();
Within your controller, add a using statement at the top:
using Microsoft.AspNetCore.Http;
and then use the HttpContext.Session object within your code like so:
[HttpGet("set/{data}")]
public IActionResult setsession(string data)
{
HttpContext.Session.SetString("keyname", data);
return Ok("session data set");
}
[HttpGet("get")]
public IActionResult getsessiondata()
{
var sessionData = HttpContext.Session.GetString("keyname");
return Ok(sessionData);
}
you should now be able to hit:
http://localhost:1234/api/session/set/thisissomedata
and then going to this URL will pull it out:
http://localhost:1234/api/session/get
Plenty more info on accessing session data within dot net core here: https://docs.microsoft.com/en-us/aspnet/core/fundamentals/app-state
Performance Concerns
Read Simon Weaver's answer below regarding performance. If you're accessing session data inside a WebApi project it can have very serious performance consequence - I have seen ASP.NET enforce a 200ms delay for concurrent requests. This could add up and become disastrous if you have many concurrent requests.
Security Concerns
Make sure you are locking down resources per user - an authenticated user shouldn't be able to retrieve data from your WebApi that they don't have access to.
Read Microsoft's article on Authentication and Authorization in ASP.NET Web API - https://www.asp.net/web-api/overview/security/authentication-and-authorization-in-aspnet-web-api
Read Microsoft's article on avoiding Cross-Site Request Forgery hack attacks. (In short, check out the AntiForgery.Validate method) - https://www.asp.net/web-api/overview/security/preventing-cross-site-request-forgery-csrf-attacks
Tested alone, <select class=input-xxlarge>
sets the content width of the element to 530px. (The total width of the element is slightly smaller than that of <input class=input-xxlarge>
due to different padding. If this a a problem, set the paddings in your own style sheet as desired.)
So if it does not work, the effect is prevented by some setting in your own style sheet or maybe in the use other settings for the element.
Over time, I have found that extracting text from PDFs in a structured format is tough business. However if you are looking for an easy solution, you might want to consider XPDF tool pdftotext
.
Pseudocode to extract the text would include:
SHELL
VBA statement to extract the text from PDF to a temporary file using XPDFSimplified example below:
Sub ReadIntoExcel(PDFName As String)
'Convert PDF to text
Shell "C:\Utils\pdftotext.exe -layout " & PDFName & " tempfile.txt"
'Read in the text file and write to Excel
Dim TextLine as String
Dim RowNumber as Integer
Dim F1 as Integer
RowNumber = 1
F1 = Freefile()
Open "tempfile.txt" for Input as #F1
While Not EOF(#F1)
Line Input #F1, TextLine
ThisWorkbook.WorkSheets(1).Cells(RowNumber, 1).Value = TextLine
RowNumber = RowNumber + 1
Wend
Close #F1
End Sub
Since this is the first Google result for 'pandas new column from others', here's a simple example:
import pandas as pd
# make a simple dataframe
df = pd.DataFrame({'a':[1,2], 'b':[3,4]})
df
# a b
# 0 1 3
# 1 2 4
# create an unattached column with an index
df.apply(lambda row: row.a + row.b, axis=1)
# 0 4
# 1 6
# do same but attach it to the dataframe
df['c'] = df.apply(lambda row: row.a + row.b, axis=1)
df
# a b c
# 0 1 3 4
# 1 2 4 6
If you get the SettingWithCopyWarning
you can do it this way also:
fn = lambda row: row.a + row.b # define a function for the new column
col = df.apply(fn, axis=1) # get column data with an index
df = df.assign(c=col.values) # assign values to column 'c'
Source: https://stackoverflow.com/a/12555510/243392
And if your column name includes spaces you can use syntax like this:
df = df.assign(**{'some column name': col.values})
Assuming df1
has all the values of x
of interest, you could use a dplyr::left_join()
to merge and then either a base::replace()
or tidyr::replace_na()
to replace the NA
s as 0
s:
library(tidyverse)
# dplyr only:
df_new <-
left_join(df1, df2, by = 'x') %>%
mutate(y = replace(y, is.na(y), 0))
# dplyr and tidyr:
df_new <-
left_join(df1, df2, by = 'x') %>%
mutate(y = replace_na(y, 0))
# In the sample data column `x` is a factor, which will give a warning with the join. This can be prevented by converting to a character before the join:
df_new <-
left_join(df1 %>% mutate(x = as.character(x)),
df2 %>% mutate(x = as.character(x)),
by = 'x') %>%
mutate(y = replace(y, is.na(y), 0))
It is quite old question but I encountered the same issue.
If you run your web on chrome, you could read through this post Background Tabs in Chrome 57
.
Basically the interval timer could run if it haven't run out of the timer budget.
The consumption of budget is based on CPU time usage of the task inside timer.
Based on my scenario, I draw video to canvas and transport to WebRTC.
The webrtc video connection would keep updating even the tab is inactive.
However you have to use setInterval
instead of requestAnimationFrame
.
it is not recommended for UI rendering though.
It would be better to listen visibilityChange
event and change render mechenism accordingly.
Besides, you could try @kaan-soral and it should works based on the documentation.
C# represents a character in UTF-16 coding rather than ASCII. Therefore converting a integer to character do not make any difference for A-Z and a-z. But I was working with ASCII Codes besides alphabets and number which did not work for me as system uses UTF-16 code. Therefore I browsed UTF-16 code for all UTF-16 character. Here is the module :
void utfchars()
{
int i, a, b, x;
ConsoleKeyInfo z;
do
{
a = 0; b = 0; Console.Clear();
for (i = 1; i <= 10000; i++)
{
if (b == 20)
{
b = 0;
a = a + 1;
}
Console.SetCursorPosition((a * 15) + 1, b + 1);
Console.Write("{0} == {1}", i, (char)i);
b = b+1;
if (i % 100 == 0)
{
Console.Write("\n\t\t\tPress any key to continue {0}", b);
a = 0; b = 0;
Console.ReadKey(true); Console.Clear();
}
}
Console.Write("\n\n\n\n\n\n\n\t\t\tPress any key to Repeat and E to exit");
z = Console.ReadKey();
if (z.KeyChar == 'e' || z.KeyChar == 'E') Environment.Exit(0);
} while (1 == 1);
}
Use a character set: [a-zA-Z]
matches one letter from A–Z in lowercase and uppercase. [a-zA-Z]+
matches one or more letters and ^[a-zA-Z]+$
matches only strings that consist of one or more letters only (^
and $
mark the begin and end of a string respectively).
If you want to match other letters than A–Z, you can either add them to the character set: [a-zA-ZäöüßÄÖÜ]
. Or you use predefined character classes like the Unicode character property class \p{L}
that describes the Unicode characters that are letters.
Since US-ASCII characters are in the byte range of 0x00–0x7F (0–127):
xxx[\x00-\x7F]+xxx
I assume you are using the caption feature of Word, that is, captions were not typed in as normal text, but were inserted using Insert > Caption (Word versions before 2007), or References > Insert Caption (in the ribbon of Word 2007 and up). If done correctly, the captions are really 'fields'. You'll know if it is a field if the caption's background turns grey when you put your cursor on them (or is permanently displayed grey).
Captions are fields - Unfortunately fields (like caption fields) are only updated on specific actions, like opening of the document, printing, switching from print view to normal view, etc. The easiest way to force updating of all (caption) fields when you want it is by doing the following:
Captions are normal text - If the caption number is not a field, I am afraid you'll have to edit the text manually.
You can use
long startTime = date.getTime() * 1000000;;
long estimatedTime = System.nanoTime() - startTime;
To get time in nano.
ArrayTest obj=new ArrayTest(1);
test.add(obj);
ArrayTest obj1=new ArrayTest(2);
test.add(obj1);
ArrayTest obj2=new ArrayTest(3);
test.add(obj2);
test.remove(object of ArrayTest);
you can specify how you control each object.
I’ve built a function I use all the time for password validation and to create passwords, e.g. to store them in a MySQL database. It uses a randomly generated salt which is way more secure than using a static salt.
function secure_password($user_pwd, $multi) {
/*
secure_password ( string $user_pwd, boolean/string $multi )
*** Description:
This function verifies a password against a (database-) stored password's hash or
returns $hash for a given password if $multi is set to either true or false
*** Examples:
// To check a password against its hash
if(secure_password($user_password, $row['user_password'])) {
login_function();
}
// To create a password-hash
$my_password = 'uber_sEcUrE_pass';
$hash = secure_password($my_password, true);
echo $hash;
*/
// Set options for encryption and build unique random hash
$crypt_options = ['cost' => 11, 'salt' => mcrypt_create_iv(22, MCRYPT_DEV_URANDOM)];
$hash = password_hash($user_pwd, PASSWORD_BCRYPT, $crypt_options);
// If $multi is not boolean check password and return validation state true/false
if($multi!==true && $multi!==false) {
if (password_verify($user_pwd, $table_pwd = $multi)) {
return true; // valid password
} else {
return false; // invalid password
}
// If $multi is boolean return $hash
} else return $hash;
}
You can add the tag as a property for the Fragment
arguments. It will be automatically restored if the fragment is destroyed and then recreated by the OS.
Example:-
final Bundle args = new Bundle();
args.putString("TAG", "my tag");
fragment.setArguments(args);
I had exactly the same problem as Ravinder Payal, and I've found the answer. Try this:
var dataURL = canvas.toDataURL("image/jpeg");
var name = "image.jpg";
var parseFile = new Parse.File(name, {base64: dataURL.substring(23)});
I was looking for a resolution to this issue in Windows, and it seems to be that if you don't have the environments vars ok, you need to put the complete directory. For eg. with a file in the same directory than PHP:
F:\myfolder\php\php.exe -f F:\myfolder\php\script.php
If you're using npm >=1.0, you can use npm link <global-package>
to create a local link to a package already installed globally. (Caveat: The OS must support symlinks.)
However, this doesn't come without its problems.
npm link is a development tool. It's awesome for managing packages on your local development box. But deploying with npm link is basically asking for problems, since it makes it super easy to update things without realizing it.
As an alternative, you can install the packages locally as well as globally.

A HashSet
holds a set of objects, but in a way that it allows you to easily and quickly determine whether an object is already in the set or not. It does so by internally managing an array and storing the object using an index which is calculated from the hashcode of the object. Take a look here
HashSet
is an unordered collection containing unique elements. It has the standard collection operations Add, Remove, Contains, but since it uses a hash-based implementation, these operations are O(1). (As opposed to List for example, which is O(n) for Contains and Remove.) HashSet
also provides standard set operations such as union, intersection, and symmetric difference. Take a look here
There are different implementations of Sets. Some make insertion and lookup operations super fast by hashing elements. However, that means that the order in which the elements were added is lost. Other implementations preserve the added order at the cost of slower running times.
The HashSet
class in C# goes for the first approach, thus not preserving the order of elements. It is much faster than a regular List
. Some basic benchmarks showed that HashSet is decently faster when dealing with primary types (int, double, bool, etc.). It is a lot faster when working with class objects. So that point is that HashSet is fast.
The only catch of HashSet
is that there is no access by indices. To access elements you can either use an enumerator or use the built-in function to convert the HashSet
into a List
and iterate through that. Take a look here

This seemed easier to think about where either of two parameters could be passed into a stored procedure. It seems to work:

What about an onclick function:
<form id="form">
<input type="text" name="firstInput">
<button type="button" name="namebutton"
onClick="$('#gif').css('visibility', 'visible');
$('#form').submit();">
</form>
Of course you can put this in a function and then trigger it with an onClick
There are two fundamental approaches to combining objects together:
The way this works is that you have an Animal object. Within that object you then add further objects that give the properties and behaviors that you require.
For example:
Now IFlier
just looks like this:
interface IFlier {
Flier getFlier();
}
So Bird
looks like this:
class Bird extends Animal implements IFlier {
Flier flier = new Flier();
public Flier getFlier() { return flier; }
}
Now you have all the advantages of Inheritance. You can re-use code. You can have a collection of IFliers, and can use all the other advantages of polymorphism, etc.
However you also have all the flexibility from Composition. You can apply as many different interfaces and composite backing class as you like to each type of Animal
- with as much control as you need over how each bit is set up.
Strategy Pattern alternative approach to composition
An alternative approach depending on what and how you are doing is to have the Animal
base class contain an internal collection to keep the list of different behaviors. In that case you end up using something closer to the Strategy Pattern. That does give advantages in terms of simplifying the code (for example Horse
doesn't need to know anything about Quadruped
or Herbivore
) but if you don't also do the interface approach you lose a lot of the advantages of polymorphism, etc.
It should be as simple as using a list of receiving variables:
scanf("%i %i %i", &var1, &var2, &var3);
This worked for me Angular cli 6.x:
import {Router} from '@angular/router';
constructor(private artistService: ArtistService, private router: Router) { }
selectRow(id: number): void{
this.router.navigate([`./artist-detail/${id}`]);
}
Most likely these classes are already defined by Bootstrap, make sure that your CSS file that you want to override the classes with is called AFTER the Bootstrap CSS.
<link rel="stylesheet" href="css/bootstrap.css" /> <!-- Call Bootstrap first -->
<link rel="stylesheet" href="css/bootstrap-override.css" /> <!-- Call override CSS second -->
Otherwise, you can put !important
at the end of your CSS like this: color:#ffffff!important;
but I would advise against using !important
at all costs.
Two options:
for (let item in MotifIntervention) {
if (isNaN(Number(item))) {
console.log(item);
}
}
Or
Object.keys(MotifIntervention).filter(key => !isNaN(Number(MotifIntervention[key])));
String enums look different than regular ones, for example:
enum MyEnum {
A = "a",
B = "b",
C = "c"
}
Compiles into:
var MyEnum;
(function (MyEnum) {
MyEnum["A"] = "a";
MyEnum["B"] = "b";
MyEnum["C"] = "c";
})(MyEnum || (MyEnum = {}));
Which just gives you this object:
{
A: "a",
B: "b",
C: "c"
}
You can get all the keys (["A", "B", "C"]
) like this:
Object.keys(MyEnum);
And the values (["a", "b", "c"]
):
Object.keys(MyEnum).map(key => MyEnum[key])
Or using Object.values():
Object.values(MyEnum)
[^0-9][+-]?[0-9]{1,10}[^0-9]
In words: Optional + or - followed by a digit, repeated one up to ten times. Note that most libraries have a shortcut for a digit: \d
, hence the above could also be written as: \d{1,10}
.
Recently had to tackle this and came up with the following after nothing quite hit everything I wanted. This will do an entire sentence, cases for special word handling. We also had issues with single character 'words' that a lot of the simpler methods handle but not the more complicated methods. Single return variable, no loops or cursors either.
CREATE FUNCTION ProperCase(@Text AS NVARCHAR(MAX))
RETURNS NVARCHAR(MAX)
AS BEGIN
DECLARE @return NVARCHAR(MAX)
SELECT @return = COALESCE(@return + ' ', '') + Word FROM (
SELECT CASE
WHEN LOWER(value) = 'llc' THEN UPPER(value)
WHEN LOWER(value) = 'lp' THEN UPPER(value) --Add as many new special cases as needed
ELSE
CASE WHEN LEN(value) = 1
THEN UPPER(value)
ELSE UPPER(LEFT(value, 1)) + (LOWER(RIGHT(value, LEN(value) - 1)))
END
END AS Word
FROM STRING_SPLIT(@Text, ' ')
) tmp
RETURN @return
END
Database clustering is a bit of an ambiguous term, some vendors consider a cluster having two or more servers share the same storage, some others call a cluster a set of replicated servers.
Replication defines the method by which a set of servers remain synchronized without having to share the storage being able to be geographically disperse, there are two main ways of going about it:
master-master (or multi-master) replication: Any server can update the database. It is usually taken care of by a different module within the database (or a whole different software running on top of them in some cases).
Downside is that it is very hard to do well, and some systems lose ACID properties when in this mode of replication.
Upside is that it is flexible and you can support the failure of any server while still having the database updated.
master-slave replication: There is only a single copy of authoritative data, which is the pushed to the slave servers.
Downside is that it is less fault tolerant, if the master dies, there are no further changes in the slaves.
Upside is that it is easier to do than multi-master and it usually preserve ACID properties.
Load balancing is a different concept, it consists distributing the queries sent to those servers so the load is as evenly distributed as possible. It is usually done at the application layer (or with a connection pool). The only direct relation between replication and load balancing is that you need some replication to be able to load balance, else you'd have a single server.
Double escaping is required when presented as a string.
Whenever I'm making a new regular expression I do a bunch of tests with online tools, for example: http://www.regexplanet.com/advanced/java/index.html
That website allows you to enter the regular expression, which it'll escape into a string for you, and you can then test it against different inputs.
I know this is a little old but I wanted to add an updated answer with f-strings which were introduced in Python version 3.6:
msg['Subject'] = f'Auto Hella Restart Report {sys.argv[1]}'
sudo apt install build-essential
is the command
But if you get the "the package can be found" kind of error, Run
sudo apt update
firstsudo apt install build-essential
This worked for me.
This should work:
select
id
,action_heading
,case when action_type='Income' then action_amount else 0 end
,case when action_type='Expense' then expense_amount else 0 end
from tbl_transaction
margin: all_four_margin
by providing 50% to all_four_margin will place the element at the center
style="margin: 50%"
you can apply it for following too
margin: top right bottom left
margin: top right&left bottom
margin: top&bottom right&left
by giving appropriate % we get the element wherever we want.
From the manual:
If the database server successfully prepares the statement, PDO::prepare() returns a PDOStatement object. If the database server cannot successfully prepare the statement, PDO::prepare() returns FALSE or emits PDOException (depending on error handling).
The prepare statement likely caused an error because the db would be unable to prepare the statement. Try testing for an error immediately after you prepare your query and before you execute it.
$qry = '
INSERT INTO non-existant-table (id, score)
SELECT id, 40
FROM another-non-existant-table
WHERE description LIKE "%:search_string%"
AND available = "yes"
ON DUPLICATE KEY UPDATE score = score + 40
';
$sth = $this->pdo->prepare($qry);
print_r($this->pdo->errorInfo());
Put that file in assets.
For project created in Android Studio project you need to create assets folder under the main folder.
Read that file as:
public String loadJSONFromAsset(Context context) {
String json = null;
try {
InputStream is = context.getAssets().open("file_name.json");
int size = is.available();
byte[] buffer = new byte[size];
is.read(buffer);
is.close();
json = new String(buffer, "UTF-8");
} catch (IOException ex) {
ex.printStackTrace();
return null;
}
return json;
}
and then you can simply read this string
return by this function as
JSONObject obj = new JSONObject(json_return_by_the_function);
For further details regarding JSON see http://www.vogella.com/articles/AndroidJSON/article.html
Hope you will get what you want.
you can use Session.Remove() method; Session.Remove
Session.Remove("yourSessionName");
If you want to use loops you can also do:
$array = array('lastname', 'email', 'phone');
foreach($array as &$value){
$value = "'$value'";
}
$comma_separated = implode(",", $array);
It's not too hard. Firstly, take a look at FileReader Interface.
So, when the form is submitted, catch the submission process and
var file = document.getElementById('fileBox').files[0]; //Files[0] = 1st file
var reader = new FileReader();
reader.readAsText(file, 'UTF-8');
reader.onload = shipOff;
//reader.onloadstart = ...
//reader.onprogress = ... <-- Allows you to update a progress bar.
//reader.onabort = ...
//reader.onerror = ...
//reader.onloadend = ...
function shipOff(event) {
var result = event.target.result;
var fileName = document.getElementById('fileBox').files[0].name; //Should be 'picture.jpg'
$.post('/myscript.php', { data: result, name: fileName }, continueSubmission);
}
Then, on the server side (i.e. myscript.php):
$data = $_POST['data'];
$fileName = $_POST['name'];
$serverFile = time().$fileName;
$fp = fopen('/uploads/'.$serverFile,'w'); //Prepends timestamp to prevent overwriting
fwrite($fp, $data);
fclose($fp);
$returnData = array( "serverFile" => $serverFile );
echo json_encode($returnData);
Or something like it. I may be mistaken (and if I am, please, correct me), but this should store the file as something like 1287916771myPicture.jpg
in /uploads/
on your server, and respond with a JSON variable (to a continueSubmission()
function) containing the fileName on the server.
Check out fwrite()
and jQuery.post()
.
On the above page it details how to use readAsBinaryString()
, readAsDataUrl()
, and readAsArrayBuffer()
for your other needs (e.g. images, videos, etc).
This XPath is specific to the code snippet you've provided. To select <child>
with id as #grand
you can write //child[@id='#grand']
.
To get age //child[@id='#grand']/@age
Hope this helps

If you want to use a function form a package or module in python you have to import and reference them. For example normally you do the following to draw 5 points( [1,5],[2,4],[3,3],[4,2],[5,1]) in the space:
import matplotlib.pyplot
matplotlib.pyplot.plot([1,2,3,4,5],[5,4,3,2,1],"bx")
matplotlib.pyplot.show()
In your solution
from matplotlib import*
This imports the package matplotlib and "plot is not defined" means there is no plot function in matplotlib you can access directly, but instead if you import as
from matplotlib.pyplot import *
plot([1,2,3,4,5],[5,4,3,2,1],"bx")
show()
Now you can use any function in matplotlib.pyplot without referencing them with matplotlib.pyplot.
I would recommend you to name imports you have, in this case you can prevent disambiguation and future problems with the same function names. The last and clean version of above example looks like:
import matplotlib.pyplot as plt
plt.plot([1,2,3,4,5],[5,4,3,2,1],"bx")
plt.show()
Date d1 = new SimpleDateFormat("yyyy-M-dd").parse((String) request.
getParameter(date1));
Date d2 = new SimpleDateFormat("yyyy-M-dd").parse((String) request.
getParameter(date2));
long diff = d2.getTime() - d1.getTime();
System.out.println("Difference between " + d1 + " and "+ d2+" is "
+ (diff / (1000 * 60 * 60 * 24)) + " days.");
You also can use some HTML5 attributes, some browsers might already take advantage of them (type="number" min="0"
).
Whatever you do, remember to re-check your inputs on the server side: you can never assume the client-side validation has been performed.
def allTheSame(i):
j = itertools.groupby(i)
for k in j: break
for k in j: return False
return True
Works in Python 2.4, which doesn't have "all".
You've forgot to define an onclick attribute to do something when the button is clicked, so nothing happening is the correct execution, see below;
<input type="button" id="moreFields" onclick="moreFields()" value="Give me more fields!" />
----------------------
Your Ruby is installed in /usr/local/Cellar/ruby/...
.
That is a restricted path and can only be written to when you use elevated privileges, either by running as root or by using sudo
. I won't recommend you run things as root since you don't understand how paths and permissions work. You can use sudo gem install jekyll
, which will temporarily elevate your permissions, giving your command the rights needed to write to that directory.
However, I'd recommend you give serious thought into NOT doing that, and instead use your RVM to install Ruby into your own home directory, where you'll automatically be able to install Rubies and gems without permission issues. See the directions for installing into a local RVM sandbox in "Single-User installations".
Because you have RVM in your ~/.bash_profile
, but it doesn't show up in your Gem environment listing, I suspect you either haven't followed the directions for installing RVM correctly, or you haven't used the all-important command:
rvm use 2.0.0 --default
to configure a default Ruby.
For most users, the "Single-User installation" is the way to go. If you have to use sudo
with that configuration you've done something wrong.
The latest answers to these type of questions (using nowadays methods) is here: Converting between strings and ArrayBuffers
Having /A without additional parameters other than the filename didn't work for me, but the following code worked fine with /n
string sfile = @".\help\delta-pqca-400-100-300-fc4-user-manual.pdf";
Process myProcess = new Process();
myProcess.StartInfo.FileName = "AcroRd32.exe";
myProcess.StartInfo.Arguments = " /n " + "\"" + sfile + "\"";
myProcess.Start();
{% if profile.user.first_name %}
works (assuming you also don't want to accept ''
).
if
in Python in general treats None
, False
, ''
, []
, {}
, ... all as false.
I move the whole directory from my Windows installation to a unix production server and I got the same error. To fix it, I just ran these two lines in unix and everything started to run fine
rm -rf app/cache/*
rm -rf app/logs/*
If you're in a situation like @Keith you could try:
print(a.__dict__)
It goes against what I would consider good style but if you're just trying to debug then it should do what you want.
Also you can use getch() from conio.h. Just like this:
...includes, defines etc
void main()
{
//operator
getch(); //now this function is waiting for any key press. When you have pressed its just //finish and next line of code will be called
}
So, because UNIX does not have conio.h, we can simulate getch() by this code (but this code already written by Vinary, my fail):
#include <stdio.h>
#include <termios.h>
#include <unistd.h>
int mygetch( ) {
struct termios oldt,

Well, in this case the car
variable will be null
, so dereferencing it (as you do when you access car.length
) will throw a NullPointerException
.
In fact, you can't access that variable at all until some value has definitely been assigned to it - otherwise the compiler will complain that "variable car might not have been initialized".
What is it you're trying to do here (it's not clear to me exactly what "solution" you're looking for)?
Just use Url.Action
instead of Html.ActionLink
:
<li id="home_nav"><a href="<%= Url.Action("ActionName") %>"><span>Span text</span></a></li>
Primitives vs. References
First :-
Primitive types are the basic types of data:
byte
, short
, int
, long
, float
, double
, boolean
, char
.
Primitive variables store primitive values.
Reference types are any instantiable class as well as arrays:
String
, Scanner
, Random
, Die
, int[]
, String[]
, etc.
Reference variables store addresses to locations in memory for where the data is stored.
Second:-
Primitive types store values but Reference type store handles to objects in heap space. Remember, reference variables are not pointers like you might have seen in C and C++, they are just handles to objects, so that you can access them and make some change on object's state.

I would like to extend nice answer of Jerome Dalbert. I found very easy to write your own annotation validators in JSR-303 way. You are not limited to have "one field" validation. You can create your own annotation on type level and have complex validation (see examples below). I prefer this way because I don't need mix different types of validation (Spring and JSR-303) like Jerome do. Also this validators are "Spring aware" so you can use @Inject/@Autowire out of box.
Example of custom object validation:
@Target({ TYPE, ANNOTATION_TYPE })
@Retention(RUNTIME)
@Constraint(validatedBy = { YourCustomObjectValidator.class })
public @interface YourCustomObjectValid {
String message() default "{YourCustomObjectValid.message}";
Class<?>[] groups() default {};
Class<? extends Payload>[] payload() default {};
}
public class YourCustomObjectValidator implements ConstraintValidator<YourCustomObjectValid, YourCustomObject> {
@Override
public void initialize(YourCustomObjectValid constraintAnnotation) { }
@Override
public boolean isValid(YourCustomObject value, ConstraintValidatorContext context) {
// Validate your complex logic
// Mark field with error
ConstraintViolationBuilder cvb = context.buildConstraintViolationWithTemplate(context.getDefaultConstraintMessageTemplate());
cvb.addNode(someField).addConstraintViolation();
return true;
}
}
@YourCustomObjectValid
public YourCustomObject {
}
Example of generic fields equality:

Don't know how you want to format it, but you can do:
print("Created at %s:%s" % (t1.hour, t1.minute))
for example.
With this method you can set font size, font style and Header background also. there are have 2 method for this
First Method
- (void)tableView:(UITableView *)tableView willDisplayHeaderView:(UIView *)view forSection:(NSInteger)section{
UITableViewHeaderFooterView *header = (UITableViewHeaderFooterView *)view;
header.backgroundView.backgroundColor = [UIColor darkGrayColor];
header.textLabel.font=[UIFont fontWithName:@"Open Sans-Regular" size:12];
[header.textLabel setTextColor:[UIColor whiteColor]];
}
Second Method
- (UIView *)tableView:(UITableView *)tableView viewForHeaderInSection:(NSInteger)section{
UILabel *myLabel = [[UILabel alloc] initWithFrame:CGRectMake(0, 0, tableView.frame.size.width, 30)];
// myLabel.frame = CGRectMake(20, 8, 320, 20);
myLabel.font = [UIFont fontWithName:@"Open Sans-Regular" size:12];
myLabel.text = [NSString stringWithFormat:@" %@",[self tableView:FilterSearchTable titleForHeaderInSection:section]];
myLabel.backgroundColor=[UIColor blueColor];
myLabel.textColor=[UIColor whiteColor];
UIView *headerView = [[UIView alloc] init];
[headerView addSubview:myLabel];
return headerView;
}
Well, what about something like this:
PS3="Select database or <Q> to quit: "
select DB in db1 db2 db3; do
[ "${REPLY^*}" = 'Q' ] && break
echo "Should backup $DB..."
done
The cmdlets in PowerShell are very nice and work reliably. Their object-orientedness appeals to me a lot since I'm a Java/C# developer, but it's not at all a complete set. Since it's object oriented, it's missed out on a lot of the text stream maturity of the POSIX tool set (awk
and sed
to name a few).
The best answer I've found to the dilemma of loving OO techniques and loving the maturity in the POSIX tools is to use both! One great aspect of PowerShell is that it does an excellent job piping objects to standard streams. PowerShell by default uses an object pipeline to transport its objects around. These aren't the standard streams (standard out, standard error, and standard in). When PowerShell needs to pass output to a standard process that doesn't have an object pipeline, it first converts the objects to a text stream. Since it does this so well, PowerShell makes an excellent place to host POSIX tools!
The best POSIX tool set is GnuWin32. It does take more than 5 seconds to install, but it's worth the trouble, and as far as I can tell, it doesn't modify your system (registry, c:\windows\*
folders, etc.) except copying files to the directories you specify. This is extra nice because if you put the tools in a shared directory, many people can access them concurrently.
Download and execute the exe (it's from the SourceForge site) pointing it to a suitable directory (I'll be using C:\bin
). It will create a GetGnuWin32
directory there in which you will run download.bat
, then install.bat
(without parameters), after which, there will be a C:\bin\GetGnuWin32\gnuwin32\bin
directory that is the most useful folder that has ever existed on a Windows machine. Add that directory to your path, and you're ready to go.
Use this method (No need to xml file)
If you want scale to quarter(half x,half y)
view.animate().scaleX(0.5f).scaleY(0.5f)
If you want scale and move to bottom right
view.animate().scaleX(0.5f).scaleY(0.5f)
.translationY((view.height/4).toFloat()).translationX((view.width/4).toFloat())
If you want move to top use (-view.height/4)
and for left (-view.width/4)
If you want do something after animation ends use withEndAction(Runnable runnable)
function.
You can use some other property like alpha and rotation
Full code
view.animate()
.scaleX(0.5f).scaleY(0.5f)//scale to quarter(half x,half y)
.translationY((view.height/4).toFloat()).translationX((view.width/4).toFloat())// move to bottom / right
.alpha(0.5f) // make it less visible
.rotation(360f) // one round turns
.setDuration(1000) // all take 1 seconds
.withEndAction(new Runnable() {
@Override
public void run() {
//animation ended
}
});
If it's a matter of just opening PDF to send some keys to it then why not try this
Sub Sample()
ActiveWorkbook.FollowHyperlink "C:\MyFile.pdf"
End Sub
I am assuming that you have some pdf reader installed.
Here is an example of reading and writing a list of objects of type SNStock
that implements NSCoding
- we have an accessor for the entire list, watchlist
, and two methods to add and remove objects, that is addStock(stock: SNStock)
and removeStock(stock: SNStock)
.
import Foundation
class DWWatchlistController {
private let kNSUserDefaultsWatchlistKey: String = "dw_watchlist_key"
private let userDefaults: NSUserDefaults
private(set) var watchlist:[SNStock] {
get {
if let watchlistData : AnyObject = userDefaults.objectForKey(kNSUserDefaultsWatchlistKey) {
if let watchlist : AnyObject = NSKeyedUnarchiver.unarchiveObjectWithData(watchlistData as! NSData) {
return watchlist as! [SNStock]
}
}
return []
}
set(watchlist) {
let watchlistData = NSKeyedArchiver.archivedDataWithRootObject(watchlist)
userDefaults.setObject(watchlistData, forKey: kNSUserDefaultsWatchlistKey)
userDefaults.synchronize()
}
}
init() {
userDefaults = NSUserDefaults.standardUserDefaults()
}
func addStock(stock: SNStock) {
var watchlist = self.watchlist
watchlist.append(stock)
self.watchlist = watchlist
}
func removeStock(stock: SNStock) {
var watchlist = self.watchlist
if let index = find(watchlist, stock) {
watchlist.removeAtIndex(index)
self.watchlist = watchlist
}
}
}
Remember that your object needs to implement NSCoding
or else the encoding won't work. Here is what SNStock
looks like:
import Foundation
class SNStock: NSObject, NSCoding
{
let ticker: NSString
let name: NSString
init(ticker: NSString, name: NSString)
{
self.ticker = ticker
self.name = name
}
//MARK: NSCoding
required init(coder aDecoder: NSCoder) {
self.ticker = aDecoder.decodeObjectForKey("ticker") as! NSString
self.name = aDecoder.decodeObjectForKey("name") as! NSString
}
func encodeWithCoder(aCoder: NSCoder) {
aCoder.encodeObject(ticker, forKey: "ticker")
aCoder.encodeObject(name, forKey: "name")
}
//MARK: NSObjectProtocol
override func isEqual(object: AnyObject?) -> Bool {
if let object = object as? SNStock {
return self.ticker == object.ticker &&
self.name == object.name
} else {
return false
}
}
override var hash: Int {
return ticker.hashValue
}
}
Hope this helps!
In 2020, I use apply()
with argument result_type='expand'
>>> appiled_df = df.apply(lambda row: fn(row.text), axis='columns', result_type='expand')
>>> df = pd.concat([df, appiled_df], axis='columns')
For all those people stuck with this problem, but still couldn't solve it: I stumbled upon the same error and found the _id
field being empty.
I described it here in more detail. Still have not found a solution except changing the fields in _id
to not-ID fields which is a dirty hack to me. I'm probably going to file a bug report for mongoose. Any help would be appreciated!
Edit: I updated my thread. I filed a ticket and they confirmed the missing _id
problem. It is going to be fixed in the 4.x.x version which has a release candidate available right now. The rc is not recommended for productive use!

if you want both always a return value but never a null value you can combine count with coalesce :
select count(field1), coalesce(field1,'any_other_default_value') from table;
that because count, will force mysql to always return a value (0 if there is no values to count) and coalesce will force mysql to always put a value that is not null
I had a doubt that whether the encrypted text will be same for single text when encryption done by multiple times on a same text??
This depends strongly on the crypto algorithm you use:
This can be accomplished in two steps:
1: select the element you want to change by either tagname, id, class etc.
var element = document.getElementsByTagName('h2')[0];
element.removeAttribute('style');
I had a similar bug, but while using a fixed number for height and not a percentage. It was also a flex container within the body (which has no specified height). It appeared that on Safari, my flex container had a height of 9px for some reason, but in all other browsers it displayed the correct 100px height specified in the stylesheet.
I managed to get it to work by adding both the height
and min-height
properties to the CSS class.
The following worked for me on both Safari 13.0.4 and Chrome 79.0.3945.130:
.flex-container {
display: flex;
flex-direction: column;
min-height: 100px;
height: 100px;
}
Hope this helps!
Googling gives me this:
Command A & Command B
Execute Command A, then execute Command B (no evaluation of anything)
Command A | Command B
Execute Command A, and redirect all its output into the input of Command B
Command A && Command B
Execute Command A, evaluate the errorlevel after running and if the exit code (errorlevel) is 0, only then execute Command B
Command A || Command B
Execute Command A, evaluate the exit code of this command and if it's anything but 0, only then execute Command B

Use Following Method to Update GUI.
Public Void UpdateUI()
{
//Here update your label, button or any string related object.
//Dispatcher.CurrentDispatcher.Invoke(DispatcherPriority.Background, new ThreadStart(delegate { }));
Application.Current.Dispatcher.Invoke(DispatcherPriority.Background, new ThreadStart(delegate { }));
}
Keep it in Mind when you use this method at that time do not Update same object direct from dispatcher thread otherwise you get only that updated string and this method is helpless/useless. If still not working then Comment that line inside method and un-comment commented one both have nearly same effect just different way to access it.
I will try to give the solution that worked for me. It seems that different set of problems can lead to this situation.
32 bit software works in 64 bit OS. I installed anaconda-3 (32 bit) in my 64 bit OS. It was working perfectly fine. I decided to install tensorflow in my machine and it wouldn't install at first. I was using conda environment to install tensorflow and got this error.
Solution is if you are running 64 bit OS, install 64 bit anaconda and if 32 bit OS then 32 bit anaconda. Then follow the standard procedure mentioned in tensorflow website for windows (anaconda installation). This made it possible to install tensorflow without any problem.
Like this :
var id = $('div.foo').attr('id');
$('div.foo').attr('id', id + ' id_adding');
Try the following:
<c:set var="count" value="0" scope="page" />
//in your loops
<c:set var="count" value="${count + 1}" scope="page"/>
If you want an efficient search that is often repeated, first sort the array (Array.Sort
) and then use Array.BinarySearch
.
I was pleased when I discovered the 0
register. If you yank text without assigning it to a particular register, then it will be assigned to the 0
register, as well as being saved in the default "
register. The difference between the 0
and "
registers is that 0
is only populated with yanked text, whereas the default register is also populated with text deleted using d
/D
/x
/X
/c
/C
/s
/S
commands.
I find this useful when I want to copy some text, delete something and replace it with the copied text. The following steps illustrate an example:
y[motion]
- this text is saved in "
and 0
registersd[motion]
- this text is saved in "
register"0p
where "
is the command to use a register for the next command.
On the final step, if you were to paste from the default register (with p
), it would use the text that you had just deleted (probably not what you intended).
Note that p
or P
pastes from the default register. The longhand equivalent would be ""p
(or ""P
) and "0
holds the last yank, "1
holds the last delete or change.
For more info see :help registers
.
This works perfectly fine with me. It takes label and format the value.
options: {
tooltips: {
callbacks: {
label: function(tooltipItem, data) {
let label = data.labels[tooltipItem.index];
let value = data.datasets[tooltipItem.datasetIndex].data[tooltipItem.index];
return ' ' + label + ': ' + value + ' %';
}
}
}
}
Add BrowserModule
to imports: []
in @NgModule()
if it's the root module (AppModule
), otherwise the CommonModule
.

..
..
@NgModule({
imports: [BrowserModule, /* or CommonModule */],

})
Using the toArray(IntFunction<A[]> generator)
method is indeed a very elegant and safe way to convert (or more correctly, collect) a Stream into an array of the same type of the Stream.
However, if the returned array's type is not important, simply using the toArray()
method is both easier and shorter.
For example:
Stream<Object> args = Stream.of(BigDecimal.ONE, "Two", 3);
System.out.printf("%s, %s, %s!", args.toArray());
I think the proxy_set_header
directive could help:
location / {
proxy_pass http://my_app_upstream;
proxy_set_header Host $host;
# ...
}
Just add this to your AndroidManifest.xml
<activity android:screenOrientation="landscape">
I mean, there is an activity tag, add this as another parameter. In case if you need portrait orientation, change landscape to portrait. Hope this helps.
This problem was solved for me by running VMware workstation as Windows administrator. From the start menu right click on the VMware workstation, then select "Run as Administrator"
You can escape (this is how this principle is called) the double quotes by prefixing them with another double quote. You can put them in a string as follows:
Dim MyVar as string = "some text ""hello"" "
This will give the MyVar
variable a value of some text "hello"
.
That's happening, because switch
statement is a statement
, but here javascript expects an expression.
Although, it's not recommended to use switch statement in a render
method, you can use self-invoking function to achieve this:
render() {
// Don't forget to return a value in a switch statement
return (
<div>
{(() => {
switch(...) {}
})()}
</div>
);
}
If you're using Google Maps v2, call checkResize()
on your map after resizing the container. link
UPDATE
Google Maps JavaScript API v2 was deprecated in 2011. It is not available anymore.
For me the above solutions were close but added some unwanted /n's and dtype:object, so here's a modified version:
df.groupby(['name', 'month'])['text'].apply(lambda text: ''.join(text.to_string(index=False))).str.replace('(\\n)', '').reset_index()
Maven advantages over ant are quite a few. I try to summarize them here.
Convention over Configuration
Maven uses a distinctive approach for the project layout and startup, that makes easy to just jump in a project. Usually it only takes the checkount and the maven command to get the artifacts of the project.
Project Modularization
Project conventions suggest (or better, force) the developer to modularize the project. Instead of a monolithic project you are often forced to divide your project in smaller sub components, which make it easier debug and manage the overall project structure
Dependency Management and Project Lifecycle
Overall, with a good SCM configuration and an internal repository, the dependency management is quite easy, and you are again forced to think in terms of Project Lifecycle - component versions, release management and so on. A little more complex than the ant something, but again, an improvement in quality of the project.
What is wrong with maven?
Maven is not easy. The build cycle (what gets done and when) is not so clear within the POM. Also, some issue arise with the quality of components and missing dependencies in public repositories.
The best approach (to me) is to have an internal repository for caching (and keeping) dependencies around, and to apply to release management of components. For projects bigger than the sample projects in a book, you will thank maven before or after
Discord doesn't allow colored text. Though, currently, you have two options to "mimic" colored text.
Discord supports Markdown and uses highlight.js to highlight code-blocks.
Some programming languages have specific color outputs from highlight.js and can be used to mimic colored output.
To use code-blocks, send a normal message in this format (Which follows Markdown's standard format).
```language
message
```
Languages that currently reproduce nice colors: prolog (red/orange), css (yellow).
Discord now supports Embeds and Webhooks, which can be used to display colored blocks, they also support markdown. For documentation on how to use Embeds, please read your lib's documentation.

It seems that the problem with IE comes when you try and access the iframe via the document.frames object - if you store a reference to the created iframe in a variable then you can access the injected iframe via the variable (my_iframe in the code below).
I've gotten this to work in IE6/7/8
var my_iframe;
var iframeId = "my_iframe_name"
if (navigator.userAgent.indexOf('MSIE') !== -1) {
// IE wants the name attribute of the iframe set
my_iframe = document.createElement('<iframe name="' + iframeId + '">');
} else {
my_iframe = document.createElement('iframe');
}
iframe.setAttribute("src", "javascript:void(0);");
iframe.setAttribute("scrolling", "no");
iframe.setAttribute("frameBorder", "0");
iframe.setAttribute("name", iframeId);
var is = iframe.style;
is.border = is.width = is.height = "0px";
if (document.body) {
document.body.appendChild(my_iframe);
} else {
document.appendChild(my_iframe);

As the internet updates I've come across a solution.
First some caveats.
First, mark your child component's encapsulation as shadow so it renders in the actual shadow dom. Second, add the part attribute to the element you wish to allow the parent to style. In your parent's component stylesheet you can use the ::part() method to access
This should work...

I struggled with the same issue when trying to feed floats to the classifiers. I wanted to keep floats and not integers for accuracy. Try using regressor algorithms. For example:

linear_model.SGDRegressor(),
linear_model.BayesianRidge(),
linear_model.LassoLars(),
linear_model.ARDRegression(),
linear_model.PassiveAggressiveRegressor(),

linear_model.LinearRegression()]

trainingScores = np.array( [3.4, 7.5, 4.5, 1.6] )
predictionData = np.array([ [2.5, 2.4, 2.7], [2.7, 3.2, 1.2] ])
for item in classifiers:
print(item)

print(clf.predict(predictionData),'\n')
You can set a custom baud rate using the stty
command on Linux. For example, to set a custom baud rate of 567890 on your serial port /dev/ttyX0, use the command:
stty -F /dev/ttyX0 567890
You can always take a look at the .size
attribute. It is defined as an integer, and is zero (0
) when there are no elements in the array:
import numpy as np
a = np.array([])
if a.size == 0:
# Do something when `a` is empty
You can also call GetSchemaTable() on your DataReader if you want the list of columns and you don't want to have to get an exception...
This should fix it:
jQuery(document).ready(function($){
//you can now use $ as your jQuery object.
var body = $( 'body' );
});
Put simply, WordPress runs their own scripting before you can and they release the $
var so it won't collide with other libraries. This makes total sense, as WordPress is used for all kinds of web sites, apps, and of course, blogs.
From their documentation:
The jQuery library included with WordPress is set to the noConflict() mode (see wp-includes/js/jquery/jquery.js). This is to prevent compatibility problems with other JavaScript libraries that WordPress can link.
In the noConflict() mode, the global $ shortcut for jQuery is not available...
To get an element by its ID, use this:
document.getElementById("p2")
Instead of:
document.getElementsByName("p2")
So the final product would be:
document.getElementsById("p2").style.visibility = "hidden";
In your main.xml include the following in your ListView:
android:drawSelectorOnTop="false"
android:listSelector="@android:color/darker_gray"
I'm using PHP
and solved this by using version 1.1.4 of google-api-php-client
Assuming the following code is used to redirect a user to the Google authentication page:
$client = new Google_Client();
$client->setAuthConfigFile('/path/to/config/file/here');
$client->setRedirectUri('https://redirect/url/here');
$client->setAccessType('offline'); //optional
$client->setScopes(['profile']); //or email
$auth_url = $client->createAuthUrl();
header('Location: ' . filter_var($auth_url, FILTER_SANITIZE_URL));
exit();
Assuming a valid authentication code is returned to the redirect_url
, the following will generate a token from the authentication code as well as provide basic profile information:
//assuming a successful authentication code is return
$authentication_code = 'code-returned-by-google';
$client = new Google_Client();
//.... configure $client object code goes here
$client->authenticate($authentication_code);
$token_data = $client->getAccessToken();
//get user email address
$google_oauth =new Google_Service_Oauth2($client);
$google_account_email = $google_oauth->userinfo->get()->email;
//$google_oauth->userinfo->get()->familyName;
//$google_oauth->userinfo->get()->givenName;
//$google_oauth->userinfo->get()->name;
//$google_oauth->userinfo->get()->gender;
//$google_oauth->userinfo->get()->picture; //profile picture
However, location is not returned. New YouTube accounts don't have YouTube specific usernames
Use which.min

df[which.min(df$Amount),]

From the help docs:
Determines the location, i.e., index of the (first) minimum or maximum of a numeric (or logical) vector.
In Visual Studio Code, the default shortcut for this is Ctrl + P.
In your comment on @Kenneth's answer you're saying that ReadAsStringAsync()
is returning empty string.
That's because you (or something - like model binder) already read the content, so position of internal stream in Request.Content is on the end.
What you can do is this:
public static string GetRequestBody()
{
var bodyStream = new StreamReader(HttpContext.Current.Request.InputStream);
bodyStream.BaseStream.Seek(0, SeekOrigin.Begin);
var bodyText = bodyStream.ReadToEnd();
return bodyText;
}
Instead of
<button ng-click="removeTask({{task.id}})">remove</button>
do this:
<button ng-click="removeTask(task.id)">remove</button>

I faced the same problem on Windows 7. My database name was test
and I got the error:
self.connection = Database.connect(**kwargs)
sqlite3.OperationalError: unable to open database file
I replaced test

and and all went smooth.
To add to the other answers, most array list implementations reserve extra capacity at the end of the list so that new elements can be added to the end of the list in O(1) time. When the capacity of an array list is exceeded, a new, larger array is allocated internally, and all the old elements are copied over. Usually, the new array is double the size of the old one. This means that on average, adding new elements to the end of an array list is an O(1) operation in these implementations. So even if you don't know the number of elements in advance, an array list may still be faster than a linked list for adding elements, as long as you are adding them at the end. Obviously, inserting new elements at arbitrary locations in an array list is still an O(n) operation.
Accessing elements in an array list is also faster than a linked list, even if the accesses are sequential. This is because array elements are stored in contiguous memory and can be cached easily. Linked list nodes can potentially be scattered over many different pages.
I would recommend only using a linked list if you know that you're going to be inserting or deleting items at arbitrary locations. Array lists will be faster for pretty much everything else.
<form action="/my/ajax/url" class="my-form">

</form>
<script>
(function($){
$("body").on("submit", ".my-form", function(e){
e.preventDefault();

$.post( form.attr("action"), form.serialize(), function(res){
console.log(res);

</script>
It is a modified version of Alfrekjv's answer
JavaScript
jQuery(document).submit(function(e){
var form = jQuery(e.target);
if(form.is("#form-id")){ // check if this is the form that you want (delete this check to apply this to all forms)
e.preventDefault();
jQuery.ajax({
type: "POST",
url: form.attr("action"),
data: form.serialize(), // serializes the form's elements.
success: function(data) {
console.log(data); // show response from the php script. (use the developer toolbar console, firefox firebug or chrome inspector console)
}
});
}
});
I wanted to edit Alfrekjv's answer but deviated too much from it so decided to post this as a separate answer.
Does not send files, does not support buttons, for example clicking a button (including a submit button) sends its value as form data, but because this is an ajax request the button click will not be sent.
To support buttons you can capture the actual button click instead of the submit.
jQuery(document).click(function(e){
var self = jQuery(e.target);
if(self.is("#form-id input[type=submit], #form-id input[type=button], #form-id button")){
e.preventDefault();
var form = self.closest('form'), formdata = form.serialize();
//add the clicked button to the form data
if(self.attr('name')){
formdata += (formdata!=='')? '&':'';
formdata += self.attr('name') + '=' + ((self.is('button'))? self.html(): self.val());
}
jQuery.ajax({
type: "POST",
url: form.attr("action"),
data: formdata,
success: function(data) {
console.log(data);
}
});
}
});
On the server side you can detect an ajax request with this header that jquery sets HTTP_X_REQUESTED_WITH
for php
PHP
if(!empty($_SERVER['HTTP_X_REQUESTED_WITH']) && strtolower($_SERVER['HTTP_X_REQUESTED_WITH']) == 'xmlhttprequest') {
//is ajax
}

You don't have to copy everything to C:\dotnet35. Usually all the files are already copied to the folder C:\Windows\WinSxS. Then the command becomes (assuming Windows was installed to C:): "Dism.exe /online /enable-feature /featurename:NetFX3 /All /Source:C:\Windows\WinSxS /LimitAccess" If not you can also point the command to the DVD directly. Then the command becomes (assuming DVD is mounted to D:): "Dism.exe /online /enable-feature /featurename:NetFX3 /All /Source:D:\sources\sxs /LimitAccess".

You can turn off the behavior AND and warning by exporting GIT_DISCOVERY_ACROSS_FILESYSTEM=1
.
On heroku, if you heroku config:set GIT_DISCOVERY_ACROSS_FILESYSTEM=1
the warning will go away.
It's probably because you are building a gem from source and the gemspec shells out to git
, like many do today. So, you'll still get the warning fatal: Not a git repository (or any of the parent directories): .git

Date.now() returns a unix timestamp in milliseconds.
const now = Date.now(); // Unix timestamp in milliseconds_x000D_
console.log( now );
_x000D_
Prior to ECMAScript5 (I.E. Internet Explorer 8 and older) you needed to construct a Date object, from which there are several ways to get a unix timestamp in milliseconds:
console.log( +new Date );_x000D_
console.log( (new Date).getTime() );_x000D_
console.log( (new Date).valueOf() );

I typically use function attributes as storage for annotations. Suppose I want to write, in the style of C# (indicating that a certain method should be part of the web service interface)
class Foo(WebService):
@webmethod
def bar(self, arg1, arg2):
...
then I can define
def webmethod(func):
func.is_webmethod = True
return func
Then, when a webservice call arrives, I look up the method, check whether the underlying function has the is_webmethod attribute (the actual value is irrelevant), and refuse the service if the method is absent or not meant to be called over the web.

.NET Core is an open source and cross platform version of .NET. Microsoft products, besides the great abilities that they have, were always expensive for usual users, especially end users of products that has been made by .NET technologies.
Most of the low-level customers prefer to use Linux as their OS and before .NET Core they would not like to use Microsoft technologies, despite the great abilities of them. But after .NET Core production, this problem is solved completely and we can satisfy our customers without considering their OS, etc.

There's also a whitepaper of a PDF creation and editing framework in Python. It's a little dated, but maybe can give you some useful info:
<?php
list($year) = explode("-", "2068-06-15");
echo $year;
?>
If, after reading the other questions and viewing the links mentioned in the comment sections, you still can't figure it out, read on.
First of all, where you're going wrong is the offset.
It should look more like this...
set mydate=%date:~10,4%%date:~6,2%/%date:~4,2%
echo %mydate%
If the date was Tue 12/02/2013
then it would display it as 2013/02/12
.
To remove the slashes, the code would look more like
set mydate=%date:~10,4%%date:~7,2%%date:~4,2%
echo %mydate%
which would output 20130212
And a hint for doing it in the future, if mydate
equals something like %date:~10,4%%date:~7,2%
or the like, you probably forgot a tilde (~).
I have faced same issue a couple of days ago while updating the database. In my case, there was few new non nullable columns added for maintenance which was not supplied in the code which is causing the exception. I figure out those fields and supplied values for them and its resolved.

change the default application for JAR files from java.exe to javaw.exe from your JAVA_HOME/bin folder.
This is because, java.exe is console application only, but JAR file needs a window rendered execution. Since javaw.exe is a window application, it is preferred for the execution of JAR files.
An alternative to this is that to some extent you can use command prompt to run your JAR files by simply using java keyword with -jar attrib.
You can use move when you need to "transfer" the content of an object somewhere else, without doing a copy (i.e. the content is not duplicated, that's why it could be used on some non-copyable objects, like a unique_ptr). It's also possible for an object to take the content of a temporary object without doing a copy (and save a lot of time), with std::move.
This link really helped me out :
http://thbecker.net/articles/rvalue_references/section_01.html
I'm sorry if my answer is coming too late, but I was also looking for a good link for the std::move, and I found the links above a little bit "austere".
This puts the emphasis on r-value reference, in which context you should use them, and I think it's more detailed, that's why I wanted to share this link here.
Yes. Thanks

There are graph databases like:
A graph database stores data as nodes and relationships/edges.This is a good fit for semi-structured data, interconnected information and domains with deep relationships/traversal, for example social networks and knowledge representation. The data model is highly flexible and "whiteboard friendly". The underlying data model of the semantic web, RDF, is also a (labeled, directed multi-)graph.
Other stackoverflow threads with information on graph databases:
An easy way to pass several arrays as parameter is to use a character-separated string. You can call your script like this:
./myScript.sh "value1;value2;value3" "somethingElse" "value4;value5" "anotherOne"
Then, you can extract it in your code like this:
myArray=$1
IFS=';' read -a myArray <<< "$myArray"
myOtherArray=$3
IFS=';' read -a myOtherArray <<< "$myOtherArray"
This way, you can actually pass multiple arrays as parameters and it doesn't have to be the last parameters.

Working with the .Parent feature, this example shows how setting only one myRng reference enables dynamic access to the entire environment without any .Select, .Activate, .Activecell, .ActiveWorkbook, .ActiveSheet and so on. (There isn't any generic .Child feature.)
Sub ShowParents()
Dim myRng As Range
Set myRng = ActiveCell
Debug.Print myRng.Address ' An address of the selected cell
Debug.Print myRng.Parent.name ' The name of sheet, where MyRng is in
Debug.Print myRng.Parent.Parent.name ' The name of workbook, where MyRng is in
Debug.Print myRng.Parent.Parent.Parent.name ' The name of application, where MyRng is in
' You may use this feature to set reference to these objects
Dim mySh As Worksheet
Dim myWbk As Workbook
Dim myApp As Application
Set mySh = myRng.Parent
Set myWbk = myRng.Parent.Parent
Set myApp = myRng.Parent.Parent.Parent
Debug.Print mySh.name, mySh.Cells(10, 1).Value
Debug.Print myWbk.name, myWbk.Sheets.Count
Debug.Print myApp.name, myApp.Workbooks.Count
' You may use dynamically addressing

' Pastes in D1 on sheet 2 in the same workbook, where the copied cell is
.Parent.Parent.Sheets(2).Range("D1").PasteSpecial xlValues

In native Hibernate XML mappings, you can accomplish this by declaring a one-to-one mapping with the constrained attribute set to true. I am not sure what the Hibernate/JPA annotation equivalent of that is, and a quick search of the doc provided no answer, but hopefully that gives you a lead to go on.
public static Bitmap RotateBitmap(Bitmap source, float angle)
{
Matrix matrix = new Matrix();
matrix.postRotate(angle);
return Bitmap.createBitmap(source, 0, 0, source.getWidth(), source.getHeight(), matrix, true);
}
To get Bitmap from resources:
Bitmap source = BitmapFactory.decodeResource(this.getResources(), R.drawable.your_img);
You are posting the data, so it should be $_POST. But 'name' is not the best name to use.
name = "name"
will only cause confusion IMO.
A little piece of PHP to get the server to populate a JavaScript variable is quick and easy:
var my_javascript_variable = <?php echo json_encode($_POST['my_post'] ?? null) ?>;
Then just access the JavaScript variable in the normal way.
Note there is no guarantee any given data or kind of data will be posted unless you check - all input fields are suggestions, not guarantees.
Solved following the suggestions and adding a piece of jQuery to force the format on integers:
parseFloat($(this).val()).toFixed(2)
You can use this function. It will replace the commas with ' ' and then it will parseFlaot the value and after that it will again adjust the commas in value.
function convertToFloat(val) {
if (val != '') {
if (val.indexOf(',') !== -1)
val.replace(',', '');
val = parseFloat(val);
while (/(\d+)(\d{3})/.test(val.toString())) {
val = val.toString().replace(/(\d+)(\d{3})/, '$1' + ',' + '$2');
}
}
return val;
}
This method uses the 'C' memset function, and is very fast (avoids a char-by-char loop).
const uint size = 65546;
char* msg = new char[size];
memset(reinterpret_cast<void*>(msg), 0, size);
Previous answers were good and correct, but in my opinion, an extra names
parameter will make it perfect, and it should be the recommended way, especially when the csv has no headers
.
usecols
and names
parametersdf = pd.read_csv(file_path, usecols=[3,6], names=['colA', 'colB'])
or use header=None
to explicitly tells people that the csv
has no headers (anyway both lines are identical)
df = pd.read_csv(file_path, usecols=[3,6], names=['colA', 'colB'], header=None)
So that you can retrieve your data by
# with `names` parameter
df['colA']
df['colB']
instead of
# without `names` parameter
df[0]
df[1]
Based on read_csv, when names
are passed explicitly, then header
will be behaving like None
instead of 0
, so one can skip header=None
when names
exist.
As others already said, there seems to be no good solution to do that easily.
But to keep your code clean I suggest creating a seperate class that hides the ugly XAML.

Tip: You can add an UserControl with name "ButtonEx" to your project in VS Studio and then copy paste the stuff above in.
Might be a very late answer, but this is good and simple.
select * from table_name order by id desc limit 5
This query will return a set of last 5 values(last 5 rows) you 've inserted in your table
Note: static synchronized methods and blocks work on the Class object.
public class MyClass {
// locks MyClass.class
public static synchronized void foo() {
// do something
}
// similar
public static void foo() {
synchronized(MyClass.class) {
// do something
}
}
}
I had the problem that my new controls would not generate in the designer file when declared in the .ascx file. The problem was that i declared them in the code behind also. So deleting the declaration in the code behind solved my problem.
you could take a look at the w3 how to, i think you will find it helpful
your link tag attribute should be rel="icon"
The system doesn't record queries in that way. If you know you want to do that ahead of time though, you can use SQL Profiler to record what is coming in and track queries during the time Profiler is running.
Within the push
method of hashHistory
, you can specify your query parameters. For instance,
history.push({
pathname: '/dresses',
search: '?color=blue'
})
or
history.push('/dresses?color=blue')
You can check out this repository for additional examples on using history
Assuming you really mean easiest and are not necessarily looking for a way to do this programmatically, you can do this:
Add, if not already there, a row of "column Musicians" to the spreadsheet. That is, if you have data in columns such as:
Rory Gallagher Guitar
Gerry McAvoy Bass
Rod de'Ath Drums
Lou Martin Keyboards
Donkey Kong Sioux Self-Appointed Semi-official Stomper
Note: you might want to add "Musician" and "Instrument" in row 0 (you might have to insert a row there)
Save the file as a CSV file.
Copy the contents of the CSV file to the clipboard
Verify that the "First row is column names" checkbox is checked
Paste the CSV data into the content area
Mash the "Convert CSV to JSON" button
With the data shown above, you will now have:
[
{
"MUSICIAN":"Rory Gallagher",
"INSTRUMENT":"Guitar"
},
{
"MUSICIAN":"Gerry McAvoy",
"INSTRUMENT":"Bass"
},
{
"MUSICIAN":"Rod D'Ath",
"INSTRUMENT":"Drums"
},
{
"MUSICIAN":"Lou Martin",
"INSTRUMENT":"Keyboards"
}
{
"MUSICIAN":"Donkey Kong Sioux",
"INSTRUMENT":"Self-Appointed Semi-Official Stomper"
}
]
With this simple/minimalistic data, it's probably not required, but with large sets of data, it can save you time and headache in the proverbial long run by checking this data for aberrations and abnormalcy.
Go here: http://jsonlint.com/
Paste the JSON into the content area
Pres the "Validate" button.
If the JSON is good, you will see a "Valid JSON" remark in the Results section below; if not, it will tell you where the problem[s] lie so that you can fix it/them.
I hope this doesn't count as spam. I humbly ended up writing a function after endless debug sessions: http://github.com/halilim/Javascript-Simple-Object-Inspect
function simpleObjInspect(oObj, key, tabLvl)
{
key = key || "";
tabLvl = tabLvl || 1;
var tabs = "";
for(var i = 1; i < tabLvl; i++){
tabs += "\t";
}
var keyTypeStr = " (" + typeof key + ")";
if (tabLvl == 1) {
keyTypeStr = "(self)";
}
var s = tabs + key + keyTypeStr + " : ";
if (typeof oObj == "object" && oObj !== null) {
s += typeof oObj + "\n";
for (var k in oObj) {
if (oObj.hasOwnProperty(k)) {
s += simpleObjInspect(oObj[k], k, tabLvl + 1);
}
}
} else {
s += "" + oObj + " (" + typeof oObj + ") \n";
}
return s;
}
Usage
alert(simpleObjInspect(anyObject));
or
console.log(simpleObjInspect(anyObject));

document.getElementById('msg').innerHTML = msg;
return false;
}

It happens when you don't properly close the code block:
if (condition){
// your code goes here*
{ // This doesn't close the code block
Correct way:
if (condition){
// your code goes here
} // Close the code block
for a single line implementation, you can use a lambda expression in a map
map(lambda x:MyModel.objects.get_or_create(name=x), items)
Here, lambda matches each item in items list to x and create a Database record if necessary.
public static <T, K, V> Collector<T, HashMap<K, V>, HashMap<K, V>> toHashMap(
Function<? super T, ? extends K> keyMapper,
Function<? super T, ? extends V> valueMapper
)
{
return Collector.of(
HashMap::new,
(map, t) -> map.put(keyMapper.apply(t), valueMapper.apply(t)),
(map1, map2) -> {
map1.putAll(map2);
return map1;
}
);
}
public static <T, K> Collector<T, HashMap<K, T>, HashMap<K, T>> toHashMap(
Function<? super T, ? extends K> keyMapper
)
{
return toHashMap(keyMapper, Function.identity());
}
This particular error implies that one of the variables being used in the arithmetic on the line has a shape incompatible with another on the same line (i.e., both different and non-scalar). Since n
and the output of np.add.reduce()
are both scalars, this implies that the problem lies with xm
and ym
, the two of which are simply your x
and y
inputs minus their respective means.
Based on this, my guess is that your x
and y
inputs have different shapes from one another, making them incompatible for element-wise multiplication.
** Technically, it's not that variables on the same line have incompatible shapes. The only problem is when two variables being added, multiplied, etc., have incompatible shapes, whether the variables are temporary (e.g., function output) or not. Two variables with different shapes on the same line are fine as long as something else corrects the issue before the mathematical expression is evaluated.
Class library is shared compiled code.
Shared project is shared source code.
Schema::table
is to modify an existing table, use Schema::create
to create new.
try this:
string.Format("{0:HH:mm:ss tt}", DateTime.Now);
for further details you can check it out : How do you get the current time of day?
use NestedScrollView
with viewport true is working good for me
<android.support.v4.widget.NestedScrollView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fillViewport="true">
<android.support.constraint.ConstraintLayout
android:layout_width="match_parent"
android:layout_height="700dp">
</android.support.constraint.ConstraintLayout>
</android.support.v4.widget.NestedScrollView>
The answer by Endoro has aged and I'm unable to comment;
# if you want to launch from a batch file or the command line:
start "" "%ProgramFiles%\Git\bin\sh.exe" --login
Project has no default.properties file! Edit the project properties to set one
best option is create new workspace import the project ,fix the project its work
I have created customize function to validate given date is between two dates or not.
var getvalidDate = function(d){ return new Date(d) }
function validateDateBetweenTwoDates(fromDate,toDate,givenDate){
return getvalidDate(givenDate) <= getvalidDate(toDate) && getvalidDate(givenDate) >= getvalidDate(fromDate);
}
For more generalised cases (including numbers with decimal point), you can try the following method:
def number?(obj)
obj = obj.to_s unless obj.is_a? String
/\A[+-]?\d+(\.[\d]+)?\z/.match(obj)
end
You can test this method in an irb session:
(irb)
>> number?(7)
=> #<MatchData "7" 1:nil>
>> !!number?(7)
=> true
>> number?(-Math::PI)
=> #<MatchData "-3.141592653589793" 1:".141592653589793">
>> !!number?(-Math::PI)
=> true
>> number?('hello world')
=> nil
>> !!number?('hello world')
=> false

StopWatch
class looks for your best solution.
Stopwatch sw = Stopwatch.StartNew();
DoSomeWork();
sw.Stop();
Console.WriteLine("Time taken: {0}ms", sw.Elapsed.TotalMilliseconds);
Also it has a static field called Stopwatch.IsHighResolution
. Of course, this is a hardware and operating system issue.
Indicates whether the timer is based on a high-resolution performance counter.
You can check out my bash-based C call tree generator here. It lets you specify one or more C functions for which you want caller and/or called information, or you can specify a set of functions and determine the reachability graph of function calls that connects them... I.e. tell me all the ways main(), foo(), and bar() are connected. It uses graphviz/dot for a graphing engine.
Using an example about for Taifun, I modified to allow expand and collapse.
... // hook up the expand/collapse all
var expandLink = $('.accordion-expand-all');
expandLink.click(function () {
$(".ui-accordion-content").toggle();
});
I know this is an old question, but gracchus's solution doesn't work if file names contain spaces. VonC's solution to file names with spaces is to not remove them utilizing --ignore-unmatch
, then remove them manually, but this will not work well if there are a lot.
Here is a solution that utilizes bash arrays to capture all files.
# Build bash array of the file names
while read -r file; do
rmlist+=( "$file" )
done < <(git ls-files -i --exclude-standard)
git rm –-cached "${rmlist[@]}"
git commit -m 'ignore update'
You can also use START WITH
to start a sequence from a particular point, although setval accomplishes the same thing, as in Euler's answer, eg,
SELECT MAX(a) + 1 FROM foo;
CREATE SEQUENCE foo_a_seq START WITH 12345; -- replace 12345 with max above
ALTER TABLE foo ALTER COLUMN a SET DEFAULT nextval('foo_a_seq');
