No, it is not okay to put a link
element in the body tag. See the specification (links to the HTML4.01 specs, but I believe it is true for all versions of HTML):
“This element defines a link. Unlike
A
, it may only appear in theHEAD
section of a document, although it may appear any number of times.”
Your friend's PC is missing the runtime support DLLs for your program:
For Spring MVC I have been trying for hours to do this and managed to have a simpler version that worked for taking form input both data and image.
<form action="/handleform" method="post" enctype="multipart/form-data">
<input type="text" name="name" />
<input type="text" name="age" />
<input type="file" name="file" />
<input type="submit" />
</form>
Controller to handle
@Controller
public class FormController {
@RequestMapping(value="/handleform",method= RequestMethod.POST)
ModelAndView register(@RequestParam String name, @RequestParam int age, @RequestParam MultipartFile file)
throws ServletException, IOException {
System.out.println(name);
System.out.println(age);
if(!file.isEmpty()){
byte[] bytes = file.getBytes();
String filename = file.getOriginalFilename();
BufferedOutputStream stream =new BufferedOutputStream(new FileOutputStream(new File("D:/" + filename)));
stream.write(bytes);
stream.flush();
stream.close();
}
return new ModelAndView("index");
}
}
Hope it helps :)
In numpy
, index and dimension numbering starts with 0. So axis 0
means the 1st dimension. Also in numpy
a dimension can have length (size) 0. The simplest case is:
In [435]: x = np.zeros((0,), int)
In [436]: x
Out[436]: array([], dtype=int32)
In [437]: x[0]
...
IndexError: index 0 is out of bounds for axis 0 with size 0
I also get it if x = np.zeros((0,5), int)
, a 2d array with 0 rows, and 5 columns.
So someplace in your code you are creating an array with a size 0 first axis.
When asking about errors, it is expected that you tell us where the error occurs.
Also when debugging problems like this, the first thing you should do is print the shape
(and maybe the dtype
) of the suspected variables.

vmin = 0.1
vmax = 1000
norm = matplotlib.colors.Normalize(np.log10(vmin), np.log10(vmax))
lognum = norm(np.log10([.5, 2., 10, 40, 150,1000]))
cdict = {
'red':

),
'green':

}
mycmap = matplotlib.colors.LinearSegmentedColormap('my_colormap', cdict, 256)
norm = matplotlib.colors.LogNorm(vmin, vmax)
colors = {}
count = 0
step_size = 0.001
for value in np.arange(vmin, vmax+step_size, step_size):
count += 1
print("%d/%d %f%%" % (count, vmax*(1./step_size), 100.*count/(vmax*(1./step_size))))
rgba = mycmap(norm(value), bytes=True)
color = (rgba[0], rgba[1], rgba[2])
if color not in colors.values():
colors[value] = color
print ("value, red, green, blue")
for value in sorted(colors.keys()):
rgb = colors[value]
print("%s, %s, %s, %s" % (value, rgb[0], rgb[1], rgb[2]))
Here is another solution (only relevant declarations listed):
.text span {
display:inline-block;
margin-right:100%;
}
When the margin is expressed in percentage, that percentage is taken from the width of the parent node, so 100% means as wide as the parent, which results in the next element getting "pushed" to a new line.
In every C++ program, all non-static functions are represented in the binary file as symbols. These symbols are special text strings that uniquely identify a function in the program.
In C, the symbol name is the same as the function name. This is possible because in C no two non-static functions can have the same name.
Because C++ allows overloading and has many features that C does not — like classes, member functions, exception specifications - it is not possible to simply use the function name as the symbol name. To solve that, C++ uses so-called name mangling, which transforms the function name and all the necessary information (like the number and size of the arguments) into some weird-looking string processed only by the compiler and linker.
So if you specify a function to be extern C, the compiler doesn't performs name mangling with it and it can be directly accessed using its symbol name as the function name.
This comes handy while using dlsym()
and dlopen()
for calling such functions.
Necromancing.
The provided answers are incomplete.
First, as already said, you cannot add multiple allow-from hosts, that's not supported.
Second, you need to dynamically extract that value from the HTTP referrer, which means that you can't add the value to Web.config, because it's not always the same value.
It will be necessary to do browser-detection to avoid adding allow-from when the browser is Chrome (it produces an error on the debug - console, which can quickly fill the console up, or make the application slow). That also means you need to modify the ASP.NET browser detection, as it wrongly identifies Edge as Chrome.
This can be done in ASP.NET by writing a HTTP-module which runs on every request, that appends a http-header for every response, depending on the request's referrer. For Chrome, it needs to add Content-Security-Policy.

You need to register the context_EndRequest function in the HTTP-module Init function.
public class RequestLanguageChanger : System.Web.IHttpModule
{
void System.Web.IHttpModule.Dispose()
{
// throw new NotImplementedException();
}
void System.Web.IHttpModule.Init(System.Web.HttpApplication context)
{
// https://stackoverflow.com/questions/441421/httpmodule-event-execution-order
context.EndRequest += new System.EventHandler(context_EndRequest);
}
// context_EndRequest Code from above comes here
}
Next you need to add the module to your application. You can either do this programmatically in Global.asax by overriding the Init function of the HttpApplication, like this:
namespace ChangeRequestLanguage
{
public class Global : System.Web.HttpApplication
{
System.Web.IHttpModule mod = new libRequestLanguageChanger.RequestLanguageChanger();
public override void Init()
{
mod.Init(this);
base.Init();
}
protected void Application_Start(object sender, System.EventArgs e)
{
}
protected void Session_Start(object sender, System.EventArgs e)
{
}
protected void Application_BeginRequest(object sender, System.EventArgs e)
{
}
protected void Application_AuthenticateRequest(object sender, System.EventArgs e)
{
}
protected void Application_Error(object sender, System.EventArgs e)
{
}
protected void Session_End(object sender, System.EventArgs e)
{
}
protected void Application_End(object sender, System.EventArgs e)
{
}
}
}
or you can add entries to Web.config if you don't own the application source-code:
<httpModules>
<add name="RequestLanguageChanger" type= "libRequestLanguageChanger.RequestLanguageChanger, libRequestLanguageChanger" />
</httpModules>
</system.web>
<system.webServer>
<validation validateIntegratedModeConfiguration="false"/>
<modules runAllManagedModulesForAllRequests="true">
<add name="RequestLanguageChanger" type="libRequestLanguageChanger.RequestLanguageChanger, libRequestLanguageChanger" />
</modules>
</system.webServer>
</configuration>
The entry in system.webServer is for IIS7+, the other in system.web is for IIS 6.
Note that you need to set runAllManagedModulesForAllRequests to true, for that it works properly.
The string in type is in the format "Namespace.Class, Assembly"
.
Note that if you write your assembly in VB.NET instead of C#, VB creates a default-Namespace for each project, so your string will look like
"[DefaultNameSpace.Namespace].Class, Assembly"
If you want to avoid this problem, write the DLL in C#.
The signature of -[NSData bytes]
is - (const void *)bytes
. You can't assign a pointer to an array on the stack. If you want to copy the buffer managed by the NSData
object into the array, use -[NSData getBytes:]
. If you want to do it without copying, then don't allocate an array; just declare a pointer variable and let NSData
manage the memory for you.
If you have just a pair of brackets ( []
) in your string, you can use indexOf()
:
String str = "ABC[ This is the text to be extracted ]";
String result = str.substring(str.indexOf("[") + 1, str.indexOf("]"));
ianhanniballake is right. You can get all the functionality of Activity
from FragmentActivity
. In fact, FragmentActivity
has more functionality.
Using FragmentActivity
you can easily build tab and swap
format. For each tab you can use different Fragment
(Fragments
are reusable). So for any FragmentActivity
you can reuse the same Fragment
.
Still you can use Activity
for single pages like list down something and edit element of the list in next page.
Also remember to use Activity
if you are using android.app.Fragment
; use FragmentActivity
if you are using android.support.v4.app.Fragment
. Never attach a android.support.v4.app.Fragment
to an android.app.Activity
, as this will cause an exception to be thrown.
If the code has already been checked out by the user that if offline and they have the latest version on their local hd, then they just need to browse to the solution location and open the solution by double clicking sln file. The solution will open in disconnected mode.
The unlikely scenario is you have a firewall between the client and the server that forces TCP reset into the connection.
I had that issue, and I found our corporate F5 firewall was configured to terminate inactive sessions that is idle for more than 5 mins.
Once again, this is the unlikely scenario.

Postgres.app was updated recently. Now it stores all the binaries in "Versions" folder
PATH="/Applications/Postgres.app/Contents/Versions/9.4/bin:$PATH"
Where 9.4 – version of PostgreSQL.

When you are defining styles for division which is positioned absolute
ly, they specifying margins are useless. Because they are no longer inside the regular DOM tree.
You can use float to do the trick.
.divtagABS {
float: left;
margin-left: auto;
margin-right:auto;
}
Method overloading deals with the notion of having two or more methods in the same class with the same name but different arguments.
void foo(int a)
void foo(int a, float b)
Method overriding means having two methods with the same arguments, but different implementations. One of them would exist in the parent class, while another will be in the derived, or child class. The @Override
annotation, while not required, can be helpful to enforce proper overriding of a method at compile time.
class Parent {
void foo(double d) {
// do something
}
}
class Child extends Parent {
@Override
void foo(double d){
// this method is overridden.
}
}
You can add as many headers as you like by calling addHeaderView() multiple times. You have to do it before setting the adapter to the list view.
And yes you can add header something like this way:
LayoutInflater inflater = getLayoutInflater();
ViewGroup header = (ViewGroup)inflater.inflate(R.layout.header, myListView, false);
myListView.addHeaderView(header, null, false);
Figured I'd share this method for clearing cookies. Perhaps it may be helpful for someone else at some point.
var cookie = document.cookie.split(';');
for (var i = 0; i < cookie.length; i++) {
var chip = cookie[i],
entry = chip.split("="),
name = entry[0];
document.cookie = name + '=; expires=Thu, 01 Jan 1970 00:00:01 GMT;';
}

One of the changes Sun
is considering for Java7
is to provide access to the inner Iterator
in foreach loops. the syntax will be something like this (if this is accepted):
for (String str : list : it) {
if (str.length() > 100) {
it.remove();
}
}
This is syntactic sugar, but apparently a lot of requests were made for this feature. But until it is approved, you'll have to count the iterations yourself, or use a regular for loop with an Iterator
.
As per official guidelines and from performance point of view they appear equivalent (ANisus answer), the s != "" would be better due to a syntactical advantage. s != "" will fail at compile time if the variable is not a string, while len(s) == 0 will pass for several other data types.
\p{L}
matches a single code point in the category "letter".
\p{N}
matches any kind of numeric character in any script.

This is a very old question, but I do not feel that the benefits of ASMX have been fairly portrayed. While not terribly flexible, ASMX web services are very simple to use and understand. While WCF is more flexible, it is also more complex to stand up and configure.
ASMX web services are ready to stand up and add as a webservice reference as soon as you add the file. (assuming your project builds)
For the simple development workflow of
create webservice
-> run webservice
-> add webservice reference
, an ASMX webservice has very little that can go wrong, not much that you can misconfigure, and that is it's strength.
In response to those that assert that WCF replaces ASMX, I would reply that WCF would need to add a streamlined K.I.S.S. configuration mode in order to completely replace ASMX.
Example web.config for an ASMX webservice:
<?xml version="1.0" encoding="utf-8"?>
<configuration>
<appSettings />
<system.web>
<compilation targetFramework="4.5" />
<httpRuntime targetFramework="4.5" />
</system.web>
</configuration>
The JDK 1.6 I'm currently using on OSX Mountain Lion did not come with a src.zip
either, and as far as i can tell there is no supported OSX JDK for 1.6 available anymore.
So I downloaded the OpenJDK source (using the links from the accepted answer (+1)) then ran:
cd ~/Downloads
mkdir jdk6src
cd jdk6src
tar xf ../openjdk-6-src-b27-26_oct_2012.tar.gz
cd jdk/src/share/classes
jar cf /System/Library/Java/JavaVirtualMachines/1.6.0.jdk/Contents/Home/src.jar *
(your file names and paths may vary...)
Associate that src.jar
with the appropriate Java platform in your IDE and you should be good to go.
There are some discrepancies between the OpenJDK source and the JDK I'm currently running (line numbers don't match up in the debugger, for one), but if all you want is a zip/jar to point your IDE to for the relatively few cases you need to peek at some code to understand how something works, then this should do the trick.
Run the following from the command prompt:
set Path="C:\Program Files\Java\jdk1.7.0_09\bin"
or
set PATH="C:\Program Files\Java\jdk1.7.0_09\bin"
I have tried this and it works well.
At the top of your .vb file:
Imports System.data.sqlclient
Within your code:
'Setup SQL Command
Dim CMD as new sqlCommand("StoredProcedureName")
CMD.parameters("@Parameter1", sqlDBType.Int).value = Param_1_value
Dim connection As New SqlConnection(connectionString)
CMD.Connection = connection
CMD.CommandType = CommandType.StoredProcedure
Dim adapter As New SqlDataAdapter(CMD)
adapter.SelectCommand.CommandTimeout = 300
'Fill the dataset
Dim DS as DataSet
adapter.Fill(ds)
connection.Close()
'Now, read through your data:
For Each DR as DataRow in DS.Tables(0).rows
Msgbox("The value in Column ""ColumnName1"": " & cstr(DR("ColumnName1")))
next
Now that the basics are out of the way,
I highly recommend abstracting the actual SqlCommand Execution out into a function.
Here is a generic function that I use, in some form, on various projects:
''' <summary>Executes a SqlCommand on the Main DB Connection. Usage: Dim ds As DataSet = ExecuteCMD(CMD)</summary>'''
''' <param name="CMD">The command type will be determined based upon whether or not the commandText has a space in it. If it has a space, it is a Text command ("select ... from .."),'''
''' otherwise if there is just one token, it's a stored procedure command</param>''''
Function ExecuteCMD(ByRef CMD As SqlCommand) As DataSet
Dim connectionString As String = ConfigurationManager.ConnectionStrings("main").ConnectionString
Dim ds As New DataSet()
Try
Dim connection As New SqlConnection(connectionString)
CMD.Connection = connection
'Assume that it's a stored procedure command type if there is no space in the command text. Example: "sp_Select_Customer" vs. "select * from Customers"
If CMD.CommandText.Contains(" ") Then
CMD.CommandType = CommandType.Text
Else
CMD.CommandType = CommandType.StoredProcedure
End If
Dim adapter As New SqlDataAdapter(CMD)
adapter.SelectCommand.CommandTimeout = 300
'fill the dataset
adapter.Fill(ds)
connection.Close()
Catch ex As Exception
' The connection failed. Display an error message.
Throw New Exception("Database Error: " & ex.Message)
End Try
Return ds
End Function
Once you have that, your SQL Execution + reading code is very simple:
'----------------------------------------------------------------------'
Dim CMD As New SqlCommand("GetProductName")
CMD.Parameters.Add("@productID", SqlDbType.Int).Value = ProductID
Dim DR As DataRow = ExecuteCMD(CMD).Tables(0).Rows(0)
MsgBox("Product Name: " & cstr(DR(0)))
'----------------------------------------------------------------------'
You can try this.

The default import method is already "relative", from the PYTHONPATH. The PYTHONPATH is by default, to some system libraries along with the folder of the original source file. If you run with -m to run a module, the current directory gets added to the PYTHONPATH. So if the entry point of your program is inside of Proj, then using import Common.Common
should work inside both Server.py and Client.py.
Don't do a relative import. It won't work how you want it to.
What happened for me when this was an issue, was that the site had used too much memory, so I'm guessing that it couldn't write to an error log or displayed the error. For clarity, it was a Wordpress site that did this. Upping the memory limit on the server showed the site again.
can test it:
describe('TableItem Components', () => {
let open_url = ""
const { open } = window;
beforeAll(() => {
delete window.open;
window.open = (url) => { open_url = url };
});
afterAll(() => {
window.open = open;
});
test('string type', async () => {
wrapper.vm.openNewTab('http://example.com')
expect(open_url).toBe('http://example.com')
})
})
For jQuery versions 1.6+ then
$('#select_all').click( function() {
$('#countries option').prop('selected', true);
});
Or for older versions:
$('#select_all').click( function() {
$('#countries option').attr('selected', 'selected');
});
Number(((Math.random() * 100) + 1).toFixed(2))
this will return a random number from 1 to 100 rounded to 2 decimal places.

Ok...so first you need to import the image into your project.
1) Select the PictureBox in the Form Design View
2) Open PictureBox Tasks
(it's the little arrow printed to right on the edge of the PictureBox)
3) Click on "Choose image..."
4) Select the second option "Project resource file:"
(this option will create a folder called "Resources" which you can access with Properties.Resources)
5) Click on "Import..." and select your image from your computer
(now a copy of the image will be saved in "Resources" folder created at step 4)
6) Click on "OK"
Now the image is in your project and you can use it with the Properties command. Just type this code when you want to change the picture in the PictureBox:
pictureBox1.Image = Properties.Resources.MyImage;
Note:
MyImage represent the name of the image...
After typing "Properties.Resources.", all imported image files are displayed...
If you really want to eke out performance (with big arrays), numexpr can be used, which takes advantage of multiple cores.
Setup:
>>> import numpy as np
>>> Data = np.random.randn(64, 64, 64, 2)
>>> x, y = Data[...,0], Data[...,1]
With numexpr
:
>>> import numexpr as ne
>>> %timeit result = ne.evaluate("complex(x, y)")
573 µs ± 21.1 µs per loop (mean ± std. dev. of 7 runs, 1000 loops each)
Compared to fast numpy method:
>>> %timeit result = np.empty(x.shape, dtype=complex); result.real = x; result.imag = y
1.39 ms ± 5.74 µs per loop (mean ± std. dev. of 7 runs, 1000 loops each)
I don't think there's anything wrong with either solutions you proposed in your question.
In my own code, I would implement it like this though:
(x for x in seq if predicate(x)).next()
The syntax with ()
creates a generator, which is more efficient than generating all the list at once with []
.
You have a numpy array of strings, not floats. This is what is meant by dtype('<U9')
-- a little endian encoded unicode string with up to 9 characters.
try:
return sum(np.asarray(listOfEmb, dtype=float)) / float(len(listOfEmb))
However, you don't need numpy here at all. You can really just do:
return sum(float(embedding) for embedding in listOfEmb) / len(listOfEmb)
Or if you're really set on using numpy.
return np.asarray(listOfEmb, dtype=float).mean()
There seems to be no way to place buttons (drawings, images) within cells in a way that would allow them to be linked to Apps Script functions.
This being said, there are some things that you can indeed do:
You can place images within cells using IMAGE(URL)
, but they cannot be linked to Apps Script functions.
You can place images within cells and link them to URLs using:
=HYPERLINK("http://example.com"; IMAGE("http://example.com/myimage.png"; 1))
You can create drawings as described in the answer of @Eduardo and they can be linked to Apps Script functions, but they will be stand-alone items that float freely "above" the spreadsheet and cannot be positioned in cells. They cannot be copied from cell to cell and they do not have a row or col position that the script function could read.
You can use the util library that comes with nodejs to get a promise from the exec command and can use that output as you need. Use restructuring to store the stdout and stderr in variables.
const util = require('util');
const exec = util.promisify(require('child_process').exec);
async function lsExample() {
const {
stdout,
stderr
} = await exec('ls');
console.log('stdout:', stdout);
console.error('stderr:', stderr);
}
lsExample();
_x000D_
input[type="text"], textarea {
background-color : #d1d1d1;
}
Hope that helps :)

Also, does Jenkins delete the artifacts after each build ? (not the archived artifacts, I know I can tell it to delete those)
No, Hudson/Jenkins does not, by itself, clear the workspace after a build. You might have actions in your build process that erase, overwrite, or move build artifacts from where you left them. There is an option in the job configuration, in Advanced Project Options (which must be expanded), called "Clean workspace before build" that will wipe the workspace at the beginning of a new build.
If you do the following, you will be able to use opencv build from OpenCV_INSTALL_PATH.
cmake_minimum_required(VERSION 2.8)

I mistakenly had written C:\Program Files\Java\
. Changing it to C:\Program Files\Java\jdk\11.0.6\
fixed the issue.
In cmd
I then checked for the version of maven
with mvn -version
.
Based on @mbaird's advice, I found a workable solution by subclassing the ImageView
class and overriding onLayout()
. I then created an observer interface which my activity implemented and passed a reference to itself to the class, which allowed it to tell the activity when it was actually finished sizing.
I'm not 100% convinced that this is the best solution (hence my not marking this answer as correct just yet), but it does work and according to the documentation is the first time when one can find the actual size of a view.
Pretty good documentation is provided on the MongoDB website
Install MongoDB
Determine which MongoDB build you need.
There are three builds of MongoDB for Windows:
MongoDB for Windows Server 2008 R2 edition (i.e. 2008R2) runs only on Windows Server 2008 R2, Windows 7 64-bit, and newer versions of Windows. This build takes advantage of recent enhancements to the Windows Platform and cannot operate on older versions of Windows.
MongoDB for Windows 64-bit runs on any 64-bit version of Windows newer than Windows XP, including Windows Server 2008 R2 and Windows 7 64-bit.
MongoDB for Windows 32-bit runs on any 32-bit version of Windows newer than Windows XP. 32-bit versions of MongoDB are only intended for older systems and for use in testing and development systems. 32-bit versions of MongoDB only support databases smaller than 2GB.
To find which version of Windows you are running, enter the following command in the Command Prompt:
wmic os get osarchitecture
Download MongoDB for Windows.
Download the latest production release of MongoDB from the MongoDB downloads page. Ensure you download the correct version of MongoDB for your Windows system. The 64-bit versions of MongoDB does not work with 32-bit Windows.
Install the downloaded file.
In Windows Explorer, locate the downloaded MongoDB msi file, which typically is located in the default Downloads folder. Double-click the msi file. A set of screens will appear to guide you through the installation process.
Move the MongoDB folder to another location (optional).
To move the MongoDB folder, you must issue the move command as an Administrator. For example, to move the folder to C:\mongodb:
Select Start Menu > All Programs > Accessories.
Right-click Command Prompt and select Run as Administrator from the popup menu.
Issue the following commands:
cd \ move C:\mongodb-win32-* C:\mongodb
MongoDB is self-contained and does not have any other system dependencies. You can run MongoDB from any folder you choose. You may install MongoDB in any folder (e.g.
D:\test\mongodb
)Run MongoDB
Warning:
Do not make
mongod.exe
visible on public networks without running in “Secure Mode” with the auth setting. MongoDB is designed to be run in trusted environments, and the database does not enable “Secure Mode” by default.
Set up the MongoDB environment.
MongoDB requires a data directory to store all data. MongoDB’s default data directory path is \data\db. Create this folder using the following commands from a Command Prompt:
md \data\db
You can specify an alternate path for data files using the
--dbpath
option tomongod.exe
, for example:C:\mongodb\bin\mongod.exe --dbpath d:\test\mongodb\data
If your path includes spaces, enclose the entire path in double quotes, for example:
C:\mongodb\bin\mongod.exe --dbpath "d:\test\mongo db data"
Start MongoDB.
To start MongoDB, run
mongod.exe
. For example, from the Command Prompt:C:\Program Files\MongoDB\bin\mongod.exe
This starts the main MongoDB database process. The waiting for connections message in the console output indicates that the mongod.exe process is running successfully.
Depending on the security level of your system, Windows may pop up a Security Alert dialog box about blocking “some features” of C:\Program Files\MongoDB\bin\mongod.exe from communicating on networks. All users should select Private Networks, such as my home or work network and click Allow access. For additional information on security and MongoDB, please see the Security Documentation.
Connect to MongoDB.
To connect to MongoDB through the mongo.exe shell, open another Command Prompt. When connecting, specify the data directory if necessary. This step provides several example connection commands.
If your MongoDB installation uses the default data directory, connect without specifying the data directory:
C:\mongodb\bin\mongo.exe
If you installation uses a different data directory, specify the directory when connecting, as in this example:
C:\mongodb\bin\mongod.exe --dbpath d:\test\mongodb\data
If your path includes spaces, enclose the entire path in double quotes. For example:
C:\mongodb\bin\mongod.exe --dbpath "d:\test\mongo db data"
If you want to develop applications using .NET, see the documentation of C# and MongoDB for more information.
Begin using MongoDB.
To begin using MongoDB, see Getting Started with MongoDB. Also consider the Production Notes document before deploying MongoDB in a production environment.
Later, to stop MongoDB, press Control+C in the terminal where the mongod instance is running.
Configure a Windows Service for MongoDB
Note:
There is a known issue for MongoDB 2.6.0, SERVER-13515, which prevents the use of the instructions in this section. For MongoDB 2.6.0, use Manually Create a Windows Service for MongoDB to create a Windows Service for MongoDB instead.
Configure directories and files.
Create a configuration file and a directory path for MongoDB log output (logpath):
Create a specific directory for MongoDB log files:
md "C:\Program Files\MongoDB\log"
In the Command Prompt, create a configuration file for the logpath option for MongoDB:
echo logpath=C:\Program Files\MongoDB\log\mongo.log > "C:\Program Files\MongoDB\mongod.cfg"
Run the MongoDB service.
Run all of the following commands in Command Prompt with “Administrative Privileges:”
Install the MongoDB service. For
--install
to succeed, you must specify the logpath run-time option."C:\Program Files\MongoDB\bin\mongod.exe" --config "C:\Program Files\MongoDB\mongod.cfg" --install
Modify the path to the mongod.cfg file as needed.
To use an alternate dbpath, specify the path in the configuration file (e.g. C:\Program Files\MongoDB\mongod.cfg) or on the command line with the --dbpath option.
If the dbpath directory does not exist, mongod.exe will not start. The default value for dbpath is
\data\db
.If needed, you can install services for multiple instances of mongod.exe or mongos.exe. Install each service with a unique
--serviceName
and--serviceDisplayName
. Use multiple instances only when sufficient system resources exist and your system design requires it.Stop or remove the MongoDB service as needed.
To stop the MongoDB service use the following command:
net stop MongoDB
To remove the MongoDB service use the following command:
"C:\Program Files\MongoDB\bin\mongod.exe" --remove
Manually Create a Windows Service for MongoDB
The following procedure assumes you have installed MongoDB using the MSI installer, with the default path C:\Program Files\MongoDB 2.6 Standard.
If you have installed in an alternative directory, you will need to adjust the paths as appropriate.
Open an Administrator command prompt.
Windows 7 / Vista / Server 2008 (and R2)
Press Win + R, then type
cmd
, then press Ctrl + Shift + Enter.Windows 8
Press Win + X, then press A.
Execute the remaining steps from the Administrator command prompt.
Create directories.
Create directories for your database and log files:
mkdir c:\data\db mkdir c:\data\log
Create a configuration file.
Create a configuration file. This file can include any of the configuration options for mongod, but must include a valid setting for logpath:
The following creates a configuration file, specifying both the logpath and the dbpath settings in the configuration file:
echo logpath=c:\data\log\mongod.log> "C:\Program Files\MongoDB 2.6 Standard\mongod.cfg" echo dbpath=c:\data\db>> "C:\Program Files\MongoDB 2.6 Standard\mongod.cfg"
Create the MongoDB service.
Create the MongoDB service.
sc.exe create MongoDB binPath= "\"C:\Program Files\MongoDB 2.6 Standard\bin\mongod.exe\" --service --config=\"C:\Program Files\MongoDB 2.6 Standard\mongod.cfg\"" DisplayName= "MongoDB 2.6 Standard" start= "auto"
sc.exe
requires a space between “=
” and the configuration values (eg “binPath=
”), and a “” to escape double quotes.If successfully created, the following log message will display:
[SC] CreateService SUCCESS
Start the MongoDB service.
net start MongoDB
Stop or remove the MongoDB service as needed.
To stop the MongoDB service, use the following command:
net stop MongoDB
To remove the MongoDB service, first stop the service and then run the following command:
sc.exe delete MongoDB
As Kristian has pointed out, good control over z-values will often solve your problems.
If that does not work you can take a look at CSS Box Shadow Bottom Only on using overflow hidden to hide excess shadow.
I would also have in mind that the box-shadow property can accept a comma-separated list of shadows like this:
box-shadow: 0px 10px 5px #888, 0px -10px 5px #888;
This will give you some control over the "amount" of shadow in each direction.
Have a look at http://www.css3.info/preview/box-shadow/ for more information about box-shadow.
Hope this was what you were looking for!
I couldn't get PSL's answer working for me so I found all I have to do is set the div holding the modal content with style="display: table;"
. The modal content itself says how big it wants to be and the modal accommodates it.
Usage
git clone <repository>
Clone the repository located at the <repository> onto the local machine. The original repository can be located on the local filesystem or on a remote machine accessible via HTTP or SSH.
git clone <repo> <directory>
Clone the repository located at <repository> into the folder called <directory> on the local machine.

Just have your menuWraper
element call event.stopPropagation()
so that its click event doesn't bubble up to the document
.
Try it out: http://jsfiddle.net/Py7Mu/
$(document).click(function() {
alert('clicked outside');
});
$(".menuWraper").click(function(event) {
alert('clicked inside');
event.stopPropagation();
});
Alternatively, you could return false;
instead of using event.stopPropagation();
git fetch && git merge origin/develop
I faced similar and tried some of the techniques mentioned here. To overcome,

if you want to do it only with the LocalDate-class:
LocalDate initial = LocalDate.of(2014, 2, 13);
LocalDate start = LocalDate.of(initial.getYear(), initial.getMonthValue(),1);
// Idea: the last day is the same as the first day of next month minus one day.
LocalDate end = LocalDate.of(initial.getYear(), initial.getMonthValue(), 1).plusMonths(1).minusDays(1);
I came across this question, and the answers here didn't work for me; i couldn't figure out why i can't login and got the above error.
It turns out that postgresql saves usernames lowercase, but during authentication it uses both upper- and lowercase.
CREATE USER myNewUser WITH PASSWORD 'passWord';
will create a user with the username 'mynewuser' and password 'passWord'.
This means you have to authenticate with 'mynewuser', and not with 'myNewUser'. For a newbie in pgsql like me, this was confusing. I hope it helps others who run into this problem.
ran across this page and several like it all talking about the GIT_DISCOVERY_ACROSS_FILESYSTEM not set message. In my case our sys admin had decided that the apache2 directory needed to be on a mounted filesystem in case the disk for the server stopped working and had to get rebuilt. I found this with a simple df command:

I my case, I solved this issue going to the Publish tab in the project properties and then select the Application Files button. Then just:
Note: Before you apply this solution, make sure that you have already (as I did), checked all your solution's projects and found no references to stdole.dll assembly.
1 - Located stdole.dll file;
2 - Changed its Publish status to Exclude
3 - After that you need to republish your application.
This issue happened on a Visual Studio 2012, after its migration from Visual Studio 2010.
Hope it helps.
I also underwent the same issue as Maven doesn't create the settings.xml
file under .m2
folder. What I did was the following and it works smoothly without any issues.
Go to the location where you maven was unzipped.
Direct to following path,
\apache-maven-3.0.4\conf\
and copy the settings.xml
file and paste it inside your .m2
folder.
Now create a maven project.
Whenever I try to drop database I get:
ERROR: database "pilot" is being accessed by other users
DETAIL: There is 1 other session using the database.
First You need to revoke
REVOKE CONNECT ON DATABASE TARGET_DB FROM public;
Then use:
SELECT pg_terminate_backend(pg_stat_activity.pid)
FROM pg_stat_activity
WHERE pg_stat_activity.datname = 'TARGET_DB';
It will surely work.
In my case, where the timezones are not available on the server, this works great:
SELECT CONVERT_TZ(`date_field`,'+00:00',@@global.time_zone) FROM `table`
Note: global.time_zone uses the server timezone. You have to make sure, that it has the desired timezone!
There is no built-in event for removing elements, but you can create one by fake-extending jQuery's default remove method. Note that the callback must be called before actually removing it to keep reference.
(function() {
var ev = new $.Event('remove'),
orig = $.fn.remove;
$.fn.remove = function() {
$(this).trigger(ev);
return orig.apply(this, arguments);
}
})();
$('#some-element').bind('remove', function() {
console.log('removed!');
// do pre-mortem stuff here
// 'this' is still a reference to the element, before removing it
});
// some other js code here [...]
$('#some-element').remove();
Note: some problems with this answer have been outlined by other posters.

length is constant which is used to find out the array storing capacity not the number of elements in the array
Example:
int[] a = new int[5]
a.length
always returns 5, which is called the capacity of an array. But
number of elements in the array is called size
Example:
int[] a = new int[5]
a[0] = 10
Here the size would be 1, but a.length
is still 5. Mind that there is no actual property or method called size
on an array so you can't just call a.size
or a.size()
to get the value 1.
The size()
method is available for collections, length
works with arrays in Java.
I use doctest[1] almost everywhere because I like the fact that I document and test my functions at the same time.
Have a look at this code:
def throw_up(something, gowrong=False):
"""
>>> throw_up('Fish n Chips')
Traceback (most recent call last):
...
Exception: Fish n Chips
>>> throw_up('Fish n Chips', gowrong=True)
'I feel fine!'
"""
if gowrong:
return "I feel fine!"
raise Exception(something)
if __name__ == '__main__':
import doctest
doctest.testmod()
If you put this example in a module and run it from the command line both test cases are evaluated and checked.

Here's a quick and dirty example of how to use an ArrayAdapter if you don't want to bother yourself with extending the mother class:
class MyClass extends Activity {
private ArrayAdapter<String> mAdapter = null;
@Override
protected void onCreate(Bundle savedInstanceState) {
mAdapter = new ArrayAdapter<String>(getApplicationContext(),
android.R.layout.simple_dropdown_item_1line, android.R.id.text1);
final ListView list = (ListView) findViewById(R.id.list);
list.setAdapter(mAdapter);
//Add Some Items in your list:
for (int i = 1; i <= 10; i++) {
mAdapter.add("Item " + i);
}
// And if you want selection feedback:
list.setOnItemClickListener(new OnItemClickListener() {
@Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
//Do whatever you want with the selected item
Log.d(TAG, mAdapter.getItem(position) + " has been selected!");
}
});
}
}
This is a huge topic, with answers from 3 lines of code to entire research magazines.
I will outline the most common such techniques and their results.
One of the simplest & fastest methods. Proposed decades ago as a means to find picture simmilarities. The idea is that a forest will have a lot of green, and a human face a lot of pink, or whatever. So, if you compare two pictures with forests, you'll get some simmilarity between histograms, because you have a lot of green in both.
Downside: it is too simplistic. A banana and a beach will look the same, as both are yellow.
OpenCV method: compareHist()
A good example here matchTemplate finding good match. It convolves the search image with the one being search into. It is usually used to find smaller image parts in a bigger one.
Downsides: It only returns good results with identical images, same size & orientation.
OpenCV method: matchTemplate()
Considered one of the most efficient ways to do image search. A number of features are extracted from an image, in a way that guarantees the same features will be recognized again even when rotated, scaled or skewed. The features extracted this way can be matched against other image feature sets. Another image that has a high proportion of the features matching the first one is considered to be depicting the same scene.
Finding the homography between the two sets of points will allow you to also find the relative difference in shooting angle between the original pictures or the amount of overlapping.
There are a number of OpenCV tutorials/samples on this, and a nice video here. A whole OpenCV module (features2d) is dedicated to it.
Downsides: It may be slow. It is not perfect.
Over on the OpenCV Q&A site I am talking about the difference between feature descriptors, which are great when comparing whole images and texture descriptors, which are used to identify objects like human faces or cars in an image.
Your Promise is pending, complete it by
userToken.then(function(result){
console.log(result)
})
after your remaining code.
All this code does is that .then()
completes your promise & captures the end result in result variable & print result in console.
Keep in mind, you cannot store the result in global variable.
Hope that explanation might help you.
Hive apparently supports INSERT...VALUES starting in Hive 0.14.
Please see the section 'Inserting into tables from SQL' at: https://cwiki.apache.org/confluence/display/Hive/LanguageManual+DML

for 1D and 2D arrays you can use np.savetxt to print using a specific format string:
>>> import sys
>>> x = numpy.arange(20).reshape((4,5))
>>> numpy.savetxt(sys.stdout, x, '%5.2f')
0.00 1.00 2.00 3.00 4.00
5.00 6.00 7.00 8.00 9.00
10.00 11.00 12.00 13.00 14.00
15.00 16.00 17.00 18.00 19.00
Your options with numpy.set_printoptions or numpy.array2string in v1.3 are pretty clunky and limited (for example no way to suppress scientific notation for large numbers). It looks like this will change with future versions, with numpy.set_printoptions(formatter=..) and numpy.array2string(style=..).
Well, this solution will help you select only current month, current week and only today
SELECT * FROM games WHERE games.published_gm = 1 AND YEAR(addedon_gm) = YEAR(NOW()) AND MONTH(addedon_gm) = MONTH(NOW()) AND DAY(addedon_gm) = DAY(NOW()) ORDER BY addedon_gm DESC;
For Weekly added posts:
WEEKOFYEAR(addedon_gm) = WEEKOFYEAR(NOW())
For Monthly added posts:
MONTH(addedon_gm) = MONTH(NOW())
For Yearly added posts:
YEAR(addedon_gm) = YEAR(NOW())
you'll get the accurate results where show only the games added today, otherwise you may display: "No New Games Found For Today". Using ShowIF recordset is empty transaction.
I faced this problem today, and the issue was I was preventing event default action in document onclick:
document.onclick = function(e) {
e.preventDefault();
}
Document onclick usually is used for event delegation but it's wrong to prevent default for every event, you must do it only for required elements:
document.onclick = function(e) {
if (e.target instanceof HTMLAnchorElement) e.preventDefault();
}

First the mysqldump command is executed and the output generated is redirected using the pipe. The pipe is sending the standard output into the gzip command as standard input. Following the filename.gz, is the output redirection operator (>) which is going to continue redirecting the data until the last filename, which is where the data will be saved.
For example, this command will dump the database and run it through gzip and the data will finally land in three.gz
mysqldump -u user -pupasswd my-database | gzip > one.gz > two.gz > three.gz
$> ls -l
-rw-r--r-- 1 uname grp 0 Mar 9 00:37 one.gz
-rw-r--r-- 1 uname grp 1246 Mar 9 00:37 three.gz
-rw-r--r-- 1 uname grp 0 Mar 9 00:37 two.gz
My original answer is an example of redirecting the database dump to many compressed files (without double compressing). (Since I scanned the question and seriously missed - sorry about that)
This is an example of recompressing files:
mysqldump -u user -pupasswd my-database | gzip -c > one.gz; gzip -c one.gz > two.gz; gzip -c two.gz > three.gz
$> ls -l
-rw-r--r-- 1 uname grp 1246 Mar 9 00:44 one.gz
-rw-r--r-- 1 uname grp 1306 Mar 9 00:44 three.gz
-rw-r--r-- 1 uname grp 1276 Mar 9 00:44 two.gz
This is a good resource explaining I/O redirection: http://www.codecoffee.com/tipsforlinux/articles2/042.html
If you are using Linux I suggest you to use the tee
command. The implementation goes like this:
python python_file.py | tee any_file_name.txt
If you don't want to change anything in the code, I think this might be the best possible solution. You can also implement logger but you need do some changes in the code.
Another answer that worked for me is (credit to http://snipt.net/Fotinakis/drop-all-tables-and-constraints-within-an-oracle-schema/)
BEGIN
FOR c IN (SELECT table_name FROM user_tables) LOOP
EXECUTE IMMEDIATE ('DROP TABLE "' || c.table_name || '" CASCADE CONSTRAINTS');
END LOOP;
FOR s IN (SELECT sequence_name FROM user_sequences) LOOP
EXECUTE IMMEDIATE ('DROP SEQUENCE ' || s.sequence_name);
END LOOP;
END;
Note that this works immediately after you run it. It does NOT produce a script that you need to paste somewhere (like other answers here). It runs directly on the DB.
You may try BulletSpan as described in Android docs.
SpannableString string = new SpannableString("Text with\nBullet point");
string.setSpan(new BulletSpan(40, color, 20), 10, 22, Spanned.SPAN_EXCLUSIVE_EXCLUSIVE);
There are a number of reasons why the analysis portion of a compiler is normally separated into lexical analysis and parsing ( syntax analysis) phases.

In addition to Temi Lajumoke's answer, it's worth noting that after creating the required roles and assigning them to specific users in ASP.NET Core 2.1 MVC Web Application, after launching the application, you may encounter a method error, such as registering or managing an account:
InvalidOperationException: Unable to resolve service for type 'Microsoft.AspNetCore.Identity.UI.Services.IEmailSender' while attempting to activate 'WebApplication.Areas.Identity.Pages.Account.Manage.IndexModel'.
A similar error can be quickly corrected in the ConfigureServices method by adding the AddDefaultUI() method:
services.AddIdentity<IdentityUser, IdentityRole>()
//services.AddDefaultIdentity<IdentityUser>()
.AddEntityFrameworkStores<ApplicationDbContext>()
.AddDefaultUI()
.AddDefaultTokenProviders();
Check
https://blogs.msdn.microsoft.com/webdev/2018/03/02/aspnetcore-2-1-identity-ui/
and related topic on github:
https://github.com/aspnet/Docs/issues/6784 for more information.
And for assigning role to specific user could be used IdentityUser class instead of ApplicationUser.
This method worked for me:
if ("username" in localStorage) {
alert('yes');
} else {
alert('no');
}
Many different ways have already been described by the other answers. However, many of them either involved ShowDialog()
or that form1
stay open but hidden. The best and most intuitive way in my opinion is to simply close form1
and then create form2
from an outside location (i.e. not from within either of those forms). In the case where form1
was created in Main
, form2
can simply be created using Application.Run
just like form1
before. Here's an example scenario:
I need the user to enter their credentials in order for me to authenticate them somehow. Afterwards, if authentication was successful, I want to show the main application to the user. In order to accomplish this, I'm using two forms: LogingForm
and MainForm
. The LoginForm
has a flag that determines whether authentication was successful or not. This flag is then used to decide whether to create the MainForm
instance or not. Neither of these forms need to know about the other and both forms can be opened and closed gracefully. Here's the code for this:
class LoginForm : Form
{
public bool UserSuccessfullyAuthenticated { get; private set; }
void LoginButton_Click(object s, EventArgs e)
{
if(AuthenticateUser(/* ... */))
{
UserSuccessfullyAuthenticated = true;
Close();
}
}
}
static class Program
{
[STAThread]
static void Main()
{
LoginForm loginForm = new LoginForm();
Application.Run(loginForm);
if(loginForm.UserSuccessfullyAuthenticated)
{
// MainForm is defined elsewhere
Application.Run(new MainForm());
}
}
}
Actually you just need to tell doctrine who's your repository class, if you don't, doctrine uses default repo instead of yours.
@ORM\Entity(repositoryClass="Company\NameOfBundle\Repository\NameOfRepository")
You can use the DataFrame apply
method:
order_df['Value'] = order_df.apply(lambda row: (row['Prices']*row['Amount']
if row['Action']=='Sell'
else -row['Prices']*row['Amount']),
axis=1)
It is usually faster to use these methods rather than over for loops.
You can change the text in the titlebar in Windows Forms by using the Text
property.
// This class is added to the namespace containing the Form1 class.
class MainApplication
{
public static void Main()
{
// Instantiate a new instance of Form1.
Form1 f1 = new Form1();
// Display a messagebox. This shows the application
// is running, yet there is nothing shown to the user.
// This is the point at which you customize your form.
System.Windows.Forms.MessageBox.Show("The application "
+ "is running now, but no forms have been shown.");
// Customize the form.
f1.Text = "Running Form";
// Show the instance of the form modally.
f1.ShowDialog();
}
}
On Windows also check whether the file is not encrypted using EFS. I had the same problem untill I decrypted the file manualy.
You don't want git revert
. That undoes a previous commit. You want git checkout
to get git's version of the file from master.
git checkout -- filename.txt
In general, when you want to perform a git operation on a single file, use -- filename
.
2020 Update
Git introduced a new command git restore
in version 2.23.0
. Therefore, if you have git version 2.23.0+
, you can simply git restore filename.txt
- which does the same thing as git checkout -- filename.txt
. The docs for this command do note that it is currently experimental.
I think most of the important stuff has been said, but I just thought I'd add one thing: If you compile as Any CPU and run on an x64 platform, then you won't be able to load 32-bit DLL files, because your application wasn't started in WoW64, but those DLL files need to run there.
If you compile as x86, then the x64 system will run your application in WoW64, and you'll be able to load 32-bit DLL files.
So I think you should choose "Any CPU" if your dependencies can run in either environment, but choose x86 if you have 32-bit dependencies. This article from Microsoft explains this a bit:
/CLRIMAGETYPE (Specify Type of CLR Image)
Incidentally, this other Microsoft documentation agrees that x86 is usually a more portable choice:
Choosing x86 is generally the safest configuration for an app package since it will run on nearly every device. On some devices, an app package with the x86 configuration won't run, such as the Xbox or some IoT Core devices. However, for a PC, an x86 package is the safest choice and has the largest reach for device deployment. A substantial portion of Windows 10 devices continue to run the x86 version of Windows.
As said earlier, currently every permission group has own permission dialog which must be called separately.
You will have different dialog boxes for each permission group but you can surely check the result together in onRequestPermissionsResult() callback method.
Even in base Python you can do the computation in generic form
result = sum(x**2 for x in some_vector) ** 0.5
x ** 2
is surely not an hack and the computation performed is the same (I checked with cpython source code). I actually find it more readable (and readability counts).
Using instead x ** 0.5
to take the square root doesn't do the exact same computations as math.sqrt
as the former (probably) is computed using logarithms and the latter (probably) using the specific numeric instruction of the math processor.
I often use x ** 0.5
simply because I don't want to add math
just for that. I'd expect however a specific instruction for the square root to work better (more accurately) than a multi-step operation with logarithms.
this question is a bit old, but I will post my answer. I have tested various INI classes (you can see them on my website) and I also use simpleIni because I want to work with INI files on both windows and winCE. Window's GetPrivateProfileString() works only with the registry on winCE.
It is very easy to read with simpleIni. Here is an example:
#include "SimpleIni\SimpleIni.h"
CSimpleIniA ini;
ini.SetUnicode();
ini.LoadFile(FileName);
const char * pVal = ini.GetValue(section, entry, DefaultStr);
In separate terminal windows do the following:
Start the broker:
mosquitto
Start the command line subscriber:
mosquitto_sub -v -t 'test/topic'
Publish test message with the command line publisher:
mosquitto_pub -t 'test/topic' -m 'helloWorld'
As well as seeing both the subscriber and publisher connection messages in the broker terminal the following should be printed in the subscriber terminal:
test/topic helloWorld
Try this:
try
{
throw new InvalidEmployeeTypeException();
input.nextLine();
}
catch(InvalidEmployeeTypeException ex)
{
//do error handling
}
continue;
Use HAVING MIN(...)
Something like:
SELECT MIN(price) AS price, pricegroup
FROM articles_prices
WHERE articleID=10
GROUP BY pricegroup
HAVING MIN(price) > 0;
You can also use showdialog
Private Sub Button3_Click(sender As System.Object, e As System.EventArgs) _
Handles Button3.Click
dim mydialogbox as new aboutbox1
aboutbox1.showdialog()
End Sub
In short: the web server issues a unique identifier to each visitor on his first visit. The visitor must bring back that ID for him to be recognised next time around. This identifier also allows the server to properly segregate objects owned by one session against that of another.
If load-on-startup is false:
If load-on-startup is true:
Once he's on the service mode and on the groove, the same servlet will work on the requests from all other clients.
Why isn't it a good idea to have one instance per client? Think about this: Will you hire one pizza guy for every order that came? Do that and you'd be out of business in no time.
It comes with a small risk though. Remember: this single guy holds all the order information in his pocket: so if you're not cautious about thread safety on servlets, he may end up giving the wrong order to a certain client.
Use strtotime("+5 minute", $date);
$date = "2017-06-16 08:40:00";
$date = strtotime($date);
$date = strtotime("+5 minute", $date);
echo date('Y-m-d H:i:s', $date);
Another alternative is to use the heatmap function in seaborn to plot the covariance. This example uses the Auto data set from the ISLR package in R (the same as in the example you showed).
import pandas.rpy.common as com
import seaborn as sns
%matplotlib inline
# load the R package ISLR
infert = com.importr("ISLR")
# load the Auto dataset
auto_df = com.load_data('Auto')
# calculate the correlation matrix
corr = auto_df.corr()
# plot the heatmap
sns.heatmap(corr,
xticklabels=corr.columns,
yticklabels=corr.columns)
If you wanted to be even more fancy, you can use Pandas Style, for example:
cmap = cmap=sns.diverging_palette(5, 250, as_cmap=True)
def magnify():
return [dict(selector="th",
props=[("font-size", "7pt")]),
dict(selector="td",
props=[('padding', "0em 0em")]),
dict(selector="th:hover",
props=[("font-size", "12pt")]),
dict(selector="tr:hover td:hover",
props=[('max-width', '200px'),
('font-size', '12pt')])
]
corr.style.background_gradient(cmap, axis=1)\
.set_properties(**{'max-width': '80px', 'font-size': '10pt'})\
.set_caption("Hover to magify")\
.set_precision(2)\
.set_table_styles(magnify())
I saw the same error after using msdeploy to copy the application to a new server. It turned out that the bindings were still using the IP address from the previous server. So, double check IP address in the IIS bindings. (Seems obvious after the fact, but did not immediately occur to me to check it).
Well, it generally depends on the shell. For bash
, it marks the variable as "exportable" meaning that it will show up in the environment for any child processes you run.
Non-exported variables are only visible from the current process (the shell).
From the bash
man page:
export [-fn] [name[=word]] ...
export -p
The supplied names are marked for automatic export to the environment of subsequently executed commands.
If the
-f
option is given, the names refer to functions. If no names are given, or if the-p
option is supplied, a list of all names that are exported in this shell is printed.The
-n
option causes the export property to be removed from each name.If a variable name is followed by
=word
, the value of the variable is set toword
.
export
returns an exit status of 0 unless an invalid option is encountered, one of the names is not a valid shell variable name, or-f
is supplied with a name that is not a function.
You can also set variables as exportable with the typeset
command and automatically mark all future variable creations or modifications as such, with set -a
.
Your cells object is not fully qualified. You need to add a DOT
before the cells object. For example
With Worksheets("Cable Cards")
.Range(.Cells(RangeStartRow, RangeStartColumn), _
.Cells(RangeEndRow, RangeEndColumn)).PasteSpecial xlValues
Similarly, fully qualify all your Cells object.
.foo {
position : relative;
}
.foo .wrapper {
background-image : url('semi-trans.png');
z-index : 10;
position : absolute;
top : 0;
left : 0;
}
<div class="foo">
<img src="example.png" />
<div class="wrapper"> </div>
</div>
I'd suggest marking the Hibernate DAO class with @Primary
, i.e. (assuming you used @Repository
on HibernateDeviceDao
):
@Primary
@Repository
public class HibernateDeviceDao implements DeviceDao
This way it will be selected as the default autowire candididate, with no need to autowire-candidate
on the other bean.
Also, rather than using @Autowired @Qualifier
, I find it more elegant to use @Resource
for picking specific beans, i.e.
@Resource(name="jdbcDeviceDao")
DeviceDao deviceDao;
This can be solved much easier than the other suggestions.
Simply draw a square and apply a border
property to just 2 joining sides.
Then rotate the square according to the direction you want the arrow to point, for exaple: transform: rotate(<your degree here>)
.triangle {_x000D_
border-right: 10px solid; _x000D_
border-bottom: 10px solid;_x000D_
height: 30px;_x000D_
width: 30px;_x000D_
transform: rotate(-45deg);_x000D_
}
_x000D_
<div class="triangle"></div>

Try instead of db.parse(xml)
:
Document doc = db.parse(new InputSource(new StringReader(**xml**)));
The documentation says:
However, JUnit Jupiter’s
org.junit.jupiter.Assertions
class does not provide anassertThat()
method like the one found in JUnit 4’sorg.junit.Assert
class which accepts a HamcrestMatcher
. Instead, developers are encouraged to use the built-in support for matchers provided by third-party assertion libraries.
Example for Hamcrest:
import static org.hamcrest.CoreMatchers.instanceOf;
import static org.hamcrest.MatcherAssert.assertThat;
import org.junit.jupiter.api.Test;
class HamcrestAssertionDemo {
@Test
void assertWithHamcrestMatcher() {
SubClass subClass = new SubClass();
assertThat(subClass, instanceOf(BaseClass.class));
}
}
Example for AssertJ:
import static org.assertj.core.api.Assertions.assertThat;
import org.junit.jupiter.api.Test;
class AssertJDemo {
@Test
void assertWithAssertJ() {
SubClass subClass = new SubClass();
assertThat(subClass).isInstanceOf(BaseClass.class);
}
}
Note that this assumes you want to test behaviors similar to instanceof
(which accepts subclasses). If you want exact equal type, I don’t see a better way than asserting the two class to be equal like you mentioned in the question.
If you will place your definitions in this order then the code will be compiled
class Ball;
class Player {
public:
void doSomething(Ball& ball);
private:
};
class Ball {
public:
Player& PlayerB;
float ballPosX = 800;
private:
};
void Player::doSomething(Ball& ball) {
ball.ballPosX += 10; // incomplete type error occurs here.
}
int main()
{
}
The definition of function doSomething requires the complete definition of class Ball because it access its data member.
In your code example module Player.cpp has no access to the definition of class Ball so the compiler issues an error.
I had the same problem. I checked netstat, other processes running, firewall and changed httpd.conf, stopped antivirus, But all my efforts were in vain. :(
So finally the solution was to stop the IIS. And it worked :)
I guess IIS and apache cant work together. If anybody know any work around let us know.
You can access the same environment variables from groovy using the same names (e.g. JOB_NAME
or env.JOB_NAME
).
From the documentation:
Environment variables are accessible from Groovy code as env.VARNAME or simply as VARNAME. You can write to such properties as well (only using the env. prefix):
env.MYTOOL_VERSION = '1.33' node { sh '/usr/local/mytool-$MYTOOL_VERSION/bin/start' }
These definitions will also be available via the REST API during the build or after its completion, and from upstream Pipeline builds using the build step.
For the rest of the documentation, click the "Pipeline Syntax" link from any Pipeline job
atoi
is a built-in function that converts a string to an integer, assuming that the string begins with an integer representation.
1. Using O(1) extra space, in O(n log n) time
This is possible, for instance:
I believe ejel's partner is correct that the best way to do this would be an in-place merge sort with a simplified merge step, and that that is probably the intent of the question, if you were eg. writing a new library function to do this as efficiently as possible with no ability to improve the inputs, and there would be cases it would be useful to do so without a hash-table, depending on the sorts of inputs. But I haven't actually checked this.
2. Using O(lots) extra space, in O(n) time
This only works if several questionable assumptions hold:
It's a bad answer, but if you have LOTS of input elements, but they're all 8-bit integers (or maybe even 16-bit integers) it could be the best way.
3. O(little)-ish extra space, O(n)-ish time
As #2, but use a hash table.
4. The clear way
If the number of elements is small, writing an appropriate algorithm is not useful if other code is quicker to write and quicker to read.
Eg. Walk through the array for each unique elements (ie. the first element, the second element (duplicates of the first having been removed) etc) removing all identical elements. O(1) extra space, O(n^2) time.
Eg. Use library functions which do this. efficiency depends which you have easily available.
The problem in your code is that you can't store the memory address of a local variable (local to a function, for example) in a globlar variable:
RectInvoice rect(vect,im,x, y, w ,h);
this->rectInvoiceVector.push_back(&rect);
There, &rect
is a temporary address (stored in the function's activation registry) and will be destroyed when that function end.
The code should create a dynamic variable:
RectInvoice *rect = new RectInvoice(vect,im,x, y, w ,h);
this->rectInvoiceVector.push_back(rect);
There you are using a heap address that will not be destroyed in the end of the function's execution. Tell me if it worked for you.
Cheers
git rm --cached file
will remove the file from the stage. That is, when you commit the file will be removed. git reset HEAD -- file
will simply reset file in the staging area to the state where it was on the HEAD commit, i.e. will undo any changes you did to it since last commiting. If that change happens to be newly adding the file, then they will be equivalent.

I solved this issue by doing this
// Created Schema - Users
// models/Users.js
const mongoose = require("mongoose");
const Schema = mongoose.Schema;
export const userSchema = new Schema({
// ...
});
Then in other files
// Another file
// index.js
import { userSchema } from "../models/Users";
const conn = mongoose.createConnection(process.env.CONNECTION_STRING, {
useNewUrlParser: true,
useUnifiedTopology: true,
});
conn.models = {};
const Users = conn.model("Users", userSchema);
const results = await Users.find({});
Better Solution
let User;
try {
User = mongoose.model("User");
} catch {
User = mongoose.model("User", userSchema);
}
I hope this helps...
You can use dd to extract arbitrary chunks of bytes.
For example,
dd skip=1234 count=5 bs=1
would copy bytes 1235 to 1239 from its input to its output, and discard the rest.
To just get the first five bytes from standard input, do:
dd count=5 bs=1
Note that, if you want to specify the input file name, dd has old-fashioned argument parsing, so you would do:
dd count=5 bs=1 if=filename
Note also that dd verbosely announces what it did, so to toss that away, do:
dd count=5 bs=1 2>&-
or
dd count=5 bs=1 2>/dev/null
Your example is perfect: the field is private and it has a getter. This is the normal way to access a field. If you need a direct access to an object field, use reflection. Using reflection to get a field's value is a hack and should be used in extreme cases such as using a library whose code you cannot change.

Generalizing on martinedwards and others' ideas, you can glue a bunch of columns together (not just a pair) by adjusting padding of even and odd column children. Adding this definition of a class, .no-gutter
, and placing it on your .row
element
.row.no-gutter > [class*='col-']:nth-child(2n+1) {
padding-right: 0;
}
.row.no-gutter > [class*='col-']:nth-child(2n) {
padding-left: 0;
}
Or in SCSS:
.no-gutter {
> [class*='col-'] {
&:nth-child(2n+1) {
padding-right: 0;
}
&:nth-child(2n) {
padding-left: 0;
}
}
}
I slightly modified your stored procedure (to use SCOPE_IDENTITY
) and it looks like this:
CREATE PROCEDURE usp_InsertContract
@ContractNumber varchar(7),
@NewId int OUTPUT
AS
BEGIN
INSERT INTO [dbo].[Contracts] (ContractNumber)
VALUES (@ContractNumber)
SELECT @NewId = SCOPE_IDENTITY()
END
I tried this and it works just fine (with that modified stored procedure):
// define connection and command, in using blocks to ensure disposal
using(SqlConnection conn = new SqlConnection(pvConnectionString ))
using(SqlCommand cmd = new SqlCommand("dbo.usp_InsertContract", conn))
{
cmd.CommandType = CommandType.StoredProcedure;
// set up the parameters
cmd.Parameters.Add("@ContractNumber", SqlDbType.VarChar, 7);
cmd.Parameters.Add("@NewId", SqlDbType.Int).Direction = ParameterDirection.Output;
// set parameter values
cmd.Parameters["@ContractNumber"].Value = contractNumber;
// open connection and execute stored procedure
conn.Open();
cmd.ExecuteNonQuery();
// read output value from @NewId
int contractID = Convert.ToInt32(cmd.Parameters["@NewId"].Value);
conn.Close();
}
Does this work in your environment, too? I can't say why your original code won't work - but when I do this here, VS2010 and SQL Server 2008 R2, it just works flawlessly....
If you don't get back a value - then I suspect your table Contracts
might not really have a column with the IDENTITY
property on it.
The following is the right method
$(document).ready(function() {
$('#btnSun').click(function(){

});
$.fn.myFunction = function() {
alert('hi');
}
});
I was getting the same error while trying to load simply HTML files that used JSON data to populate the page, so I used used node.js and express to solve the problem. If you do not have node installed, you need to install node first.
Install express
npm install express
Create a server.js file in the root folder of your project, in my case one folder above the files I wanted to server
Put something like the following in the server.js file and read about this on the express gihub site:
var express = require('express');
var app = express();
var path = require('path');
// __dirname will use the current path from where you run this file
app.use(express.static(__dirname));
app.use(express.static(path.join(__dirname, '/FOLDERTOHTMLFILESTOSERVER')));
app.listen(8000);
console.log('Listening on port 8000');
After you've saved server.js, you can run the server using:
node server.js
http://localhost:8000/FILENAME
and you should see the HTML file you were trying to loadI have a unique situation where I can benchmark the solutions proposed on this page, and so I'm writing this answer as a consolidation of the proposed solutions with included run times for each.
Set Up
I have a 3.261 gigabyte ASCII text data file with one key-value pair per row. The file contains 3,339,550,320 rows in total and defies opening in any editor I have tried, including my go-to Vim. I need to subset this file in order to investigate some of the values that I've discovered only start around row ~500,000,000.
Because the file has so many rows:
My best-case-scenario is a solution that extracts only a single line from the file without reading any of the other rows in the file, but I can't think of how I would accomplish this in Bash.
For the purposes of my sanity I'm not going to be trying to read the full 500,000,000 lines I'd need for my own problem. Instead I'll be trying to extract row 50,000,000 out of 3,339,550,320 (which means reading the full file will take 60x longer than necessary).
I will be using the time
built-in to benchmark each command.

First let's see how the head
tail
solution:
$ time head -50000000 myfile.ascii | tail -1
pgm_icnt = 0
real 1m15.321s
The baseline for row 50 million is 00:01:15.321, if I'd gone straight for row 500 million it'd probably be ~12.5 minutes.
cut
I'm dubious of this one, but it's worth a shot:
$ time cut -f50000000 -d$'\n' myfile.ascii
pgm_icnt = 0
real 5m12.156s
This one took 00:05:12.156 to run, which is much slower than the baseline! I'm not sure whether it read through the entire file or just up to line 50 million before stopping, but regardless this doesn't seem like a viable solution to the problem.
AWK
I only ran the solution with the exit
because I wasn't going to wait for the full file to run:
$ time awk 'NR == 50000000 {print; exit}' myfile.ascii
pgm_icnt = 0
real 1m16.583s
This code ran in 00:01:16.583, which is only ~1 second slower, but still not an improvement on the baseline. At this rate if the exit command had been excluded it would have probably taken around ~76 minutes to read the entire file!
Perl
I ran the existing Perl solution as well:
$ time perl -wnl -e '$.== 50000000 && print && exit;' myfile.ascii
pgm_icnt = 0
real 1m13.146s
This code ran in 00:01:13.146, which is ~2 seconds faster than the baseline. If I'd run it on the full 500,000,000 it would probably take ~12 minutes.
sed
The top answer on the board, here's my result:
$ time sed "50000000q;d" myfile.ascii
pgm_icnt = 0
real 1m12.705s
This code ran in 00:01:12.705, which is 3 seconds faster than the baseline, and ~0.4 seconds faster than Perl. If I'd run it on the full 500,000,000 rows it would have probably taken ~12 minutes.
mapfile
I have bash 3.1 and therefore cannot test the mapfile solution.
Conclusion
It looks like, for the most part, it's difficult to improve upon the head
tail
solution. At best the sed
solution provides a ~3% increase in efficiency.

Get the readable date from timestamp with time also, also you can change the format of the date.

This type of error will come when you try to upload backup data from a higher version to lower version. Like you have backup of SQL server 2008 and you trying to upload data into SQL server 2005 then you will get this kind of error. Please try to upload in a higher version.

If you start tinkering with VirtualBox network settings, watch out for this: you might make new network adapters (eth1, eth2), yet have your /etc/network/interfaces
still configured for eth0.
Diagnose:
ethtool -i eth0
Cannot get driver information: no such device
Find your interfaces:
ls /sys/class/net
eth1 eth2 lo
Fix it:
Edit /etc/networking/interfaces
and replace eth0 with the appropriate interface name (e.g eth1, eth2, etc.)
:%s/eth0/eth2/g
Try following code;
DropDownList1.Items.Add(new ListItem(txt_box1.Text));
It's interesting things with IDE (IntelliJ in this case):
if you leave default, i.e. don't declare spring-boot-starter-tomcat as provided, a spring-boot-maven-plugin (SBMP) put tomcat's jars to your war -> and you'll probably get errors deploying this war to container (there could be a versions conflict)
else you'll get classpath with no compile dependency on tomcat-embed (SBMP will build executable war/jar with provided deps included anyway)
There is some tricky workaround: put Tomcat's jars to classpath of your idea-module via UI: File->Project Structure->(Libraries or Modules/Dependencies tab)
.
maven
caseInstead of adding module dependencies in Idea, it is better to declare maven profile with compile scope of spring-boot-starter-tomcat library.
<profiles>
<profile>
<id>embed-tomcat</id>
<dependencies>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-tomcat</artifactId>
<scope>compile</scope>
</dependency>
</dependencies>
</profile>
</profiles>
while spring-boot-starter-tomcat
was declared provided in <dependencies/>
, making this profile active in IDE or CLI (mvn -Pembed-tomcat ...
) allow you to launch build with embedded tomcat.
This is a followup to the font-forge
section of @Kurt Pfeifle's answer, specific to Red Hat (and possibly other Linux distros).
Once you have your TTF file, you can install it on your system by
/usr/share/fonts
(as root)fc-cache -f /usr/share/fonts/
(as root)In view file (HTML or EJS)
<div ng-repeat="item in vm.itemList | filter: myFilter > </div>
and In Controller
$scope.myFilter = function(item) {
return (item.propertyA === 'value' || item.propertyA === 'value');
}
rm -rf
was much more performant than FileUtils.cleanDirectory
.Not a one-liner solution but after extensive benchmarking, we found that using rm -rf
was multiple times faster than using FileUtils.cleanDirectory
.
Of course, if you have a small or simple directory, it won't matter but in our case we had multiple gigabytes and deeply nested sub directories where it would take over 10 minutes with FileUtils.cleanDirectory
and only 1 minute with rm -rf
.
Here's our rough Java implementation to do that:
// Delete directory given and all subdirectories and files (i.e. recursively).
//
static public boolean clearDirectory( File file ) throws IOException, InterruptedException {
if ( file.exists() ) {
String deleteCommand = "rm -rf " + file.getAbsolutePath();
Runtime runtime = Runtime.getRuntime();
Process process = runtime.exec( deleteCommand );
process.waitFor();
file.mkdirs(); // Since we only want to clear the directory and not delete it, we need to re-create the directory.
return true;
}
return false;
}
Worth trying if you're dealing with large or complex directories.
In general don't expose List<T>
publicly, and don't provide setters for collection properties. Also, you may want to copy the elements of the passed list (as shown below). Otherwise changes to the original list will affect the Human instance.
public class Human
{
public Human()
{
}
public Human(IEnumerable<ContactNumber> contactNumbers)
{
if (contactNumbers == null)
{
throw new ArgumentNullException("contactNumbers");
}
_contactNumbers.AddRange(contactNumbers);
}
public IEnumerable<ContactNumber> ContactNumbers
{
get { return _contactNumbers; }
}
private readonly List<ContactNumber> _contactNumbers = new List<ContactNumber>();
}
Another option is to use the list constructor that takes a collection and remove the field initializer.
You can also do
console.log("a = %o, b = %o", a, b);
where a and b are objects.
Unfortunately MySQL does not support SQL check constraints. You can define them in your DDL query for compatibility reasons but they are just ignored.
There is a simple alternative
You can create BEFORE INSERT
and BEFORE UPDATE
triggers which either cause an error or set the field to its default value when the requirements of the data are not met.
Example for BEFORE INSERT
working after MySQL 5.5
DELIMITER $$
CREATE TRIGGER `test_before_insert` BEFORE INSERT ON `Test`
FOR EACH ROW
BEGIN
IF CHAR_LENGTH( NEW.ID ) < 4 THEN
SIGNAL SQLSTATE '12345'
SET MESSAGE_TEXT := 'check constraint on Test.ID failed';
END IF;
END$$
DELIMITER ;
Prior to MySQL 5.5 you had to cause an error, e.g. call a undefined procedure.
In both cases this causes an implicit transaction rollback. MySQL does not allow the ROLLBACK statement itself within procedures and triggers.
If you don't want to rollback the transaction ( INSERT / UPDATE should pass even with a failed "check constraint" you can overwrite the value using SET NEW.ID = NULL
which will set the id to the fields default value, doesn't really make sense for an id tho
Edit: Removed the stray quote.
Concerning the :=
operator:
Unlike
=
, the:=
operator is never interpreted as a comparison operator. This means you can use:=
in any valid SQL statement (not just in SET statements) to assign a value to a variable.
https://dev.mysql.com/doc/refman/5.6/en/assignment-operators.html
Concerning backtick identifier quotes:
The identifier quote character is the backtick (“`”)
If the ANSI_QUOTES SQL mode is enabled, it is also permissible to quote identifiers within double quotation marks
Currently evaluation in the console is performed in the context of the main frame in the page and it adheres to the same cross-origin policy as the main frame itself. This means that you cannot access elements in the iframe unless the main frame can. You can still set breakpoints in and debug your code using Scripts panel though.
Update: This is no longer true. See Metagrapher's answer.
Unless the role was made dbo, db_owner or db_datawriter, it won't have permission to edit any data. If you want to grant full edit permissions to a single table, do this:
GRANT ALL ON table1 TO doctor
Users in that role will have no permissions whatsoever to other tables (not even read).
You have done it correctly. The pull request will automatically update. The process is:
The pull request will automatically add the new commits at the bottom of the pull request discussion (ie, it's already there, scroll down!)
If the indexes are continuous:
foreach ($arr as $key => $val) {
if (isset($arr[$key+1])) {
echo $arr[$key+1]; // next element
} else {
// end of array reached
}
}
Easiest way: change the Windows Display Properties main window background color. I went to Appearance tab, changed to Silver scheme, clicked Advanced, clicked on "Active Window" and changed Color 1 to a light gray. All Eclipse views softened.
Since Luna (4.4) there seems to be a full Dark
them in
Window -> Preferences -> General -> Appearance -> Theme -> Dark
first store the values in $rootScope as
.run(function($rootScope){
$rootScope.myData = {name : "nikhil"}
})
.controller('myCtrl', function($scope) {
var a ="Nikhilesh";
$scope.myData.name = a;
});
.controller('myCtrl2', function($scope) {
var b = $scope.myData.name;
)}
$rootScope is the parent of all $scope, each $scope receives a copy of $rootScope data which you can access using $scope itself.
return;
will exit a method in C#.
See code snippet below
using System;
namespace Exercise_strings
{
class Program
{
static void Main(string[] args)
{
Console.WriteLine("Input string separated by -");
var stringInput = Console.ReadLine();
if (string.IsNullOrWhiteSpace(stringInput))
{
Console.WriteLine("Nothing entered");
return;
}
}
So in this case if a user enters a null string or whitespace, the use of the return method terminates the Main method elegantly.
You can flip it horizontally with CSS...
a:visited {
-moz-transform: scaleX(-1);
-o-transform: scaleX(-1);
-webkit-transform: scaleX(-1);
transform: scaleX(-1);
filter: FlipH;
-ms-filter: "FlipH";
}
If you want to flip vertically instead...
a:visited {
-moz-transform: scaleY(-1);
-o-transform: scaleY(-1);
-webkit-transform: scaleY(-1);
transform: scaleY(-1);
filter: FlipV;
-ms-filter: "FlipV";
}
I did this:
click SDk Manager:
Change in updates to Canary Channel, check and update it...
After go in build.gradle and change the compile version to 26.0.0-beta2:
After go in gradle/build.gradle and change dependencies classpath 'com.android.tools.build:gradle:3.0.0-alpha7':
After sync the project... It works to me! I hope I've helped... tks!
Please remove . from your target it should be a id
<a href="#bannerformmodal" data-toggle="modal" data-target="#bannerformmodal">Load me</a>
Also you have to give your modal id like below
<div class="modal fade bannerformmodal" tabindex="-1" role="dialog" aria-labelledby="bannerformmodal" aria-hidden="true" id="bannerformmodal">
In its most basic incarnation..
JavaScript:
<script>
var i = 0;
function buttonClick() {
document.getElementById('inc').value = ++i;
}
</script>
Markup:
<button onclick="buttonClick()">Click Me</button>
<input type="text" id="inc" value="0"></input>
There is an another issue about connection. Some android versions can connect but some cannot. So there is an another solution
in AndroidManifest.xml:
<application ... android:usesCleartextTraffic="true">_x000D_
..._x000D_
</application>
_x000D_
Just add 'android:usesCleartextTraffic="true"'
and problem solved finally.
In general you can extract a string from object with the class name,
str_class = object.__class__.__name__
and using it for comparison,
if str_class == 'dict':
# blablabla..
elif str_class == 'customclass':
# blebleble..
return $this->output
->set_content_type('application/json')
->set_status_header(500)
->set_output(json_encode(array(
'text' => 'Error 500',
'type' => 'danger'
)));
A simpler and imho better solution is:
Console.Write("\r" + new string(' ', Console.WindowWidth) + "\r");
It uses the carriage return to go to the beginning of the line, then prints as many spaces as the console is width and returns to the beginning of the line again, so you can print your own test afterwards.
try
states.split()
it returns the list
['Alaska',
'Alabama',
'Arkansas',
'American',
'Samoa',
'Arizona',
'California',
'Colorado']
and this returns the random element of the list
import random
random.choice(states.split())
split statement parses the string and returns the list, by default it's divided into the list by spaces, if you specify the string it's divided by this string, so for example
states.split('Ari')
returns
['Alaska Alabama Arkansas American Samoa ', 'zona California Colorado']
Btw, list is in python interpretated with [] brackets instead of {} brackets, {} brackets are used for dictionaries, you can read more on this here
I see you are probably new to python, so I'd give you some advice how to use python's great documentation
Almost everything you need can be found here You can use also python included documentation, open python console and write help() If you don't know what to do with some object, I'd install ipython, write statement and press Tab, great tool which helps you with interacting with the language
I just wrote this here to show that python is great tool also because it's great documentation and it's really powerful to know this
Use curl
instead of file_get_contents
:
$address = "India+Panchkula";
$url = "http://maps.google.com/maps/api/geocode/json?address=$address&sensor=false®ion=India";
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_PROXYPORT, 3128);
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 0);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0);
$response = curl_exec($ch);
curl_close($ch);
$response_a = json_decode($response);
echo $lat = $response_a->results[0]->geometry->location->lat;
echo "<br />";
echo $long = $response_a->results[0]->geometry->location->lng;
yes, it may work in KITKAT.
above KITKAT+ it will go to internal storage:paths like(storage/emulated/0).
please think, how "Xender app" give permission to write in to external sd card.
So, Fortunately in Android 5.0 and later there is a new official way for apps to write to the external SD card. Apps must ask the user to grant write access to a folder on the SD card. They open a system folder chooser dialog. The user need to navigate into that specific folder and select it.
for more details, please refer https://metactrl.com/docs/sdcard-on-lollipop/
There's a headers parameter in the config object you pass to $http
for per-call headers:
$http({method: 'GET', url: 'www.google.com/someapi', headers: {
'Authorization': 'Basic QWxhZGRpbjpvcGVuIHNlc2FtZQ=='}
});
Or with the shortcut method:
$http.get('www.google.com/someapi', {
headers: {'Authorization': 'Basic QWxhZGRpbjpvcGVuIHNlc2FtZQ=='}
});
The list of the valid parameters is available in the $http service documentation.
Too much magic.
https://golang.org/src/time/format.go specified
For parsing time 15
is used for Hours, 04
is used for minutes, 05
for seconds.
For parsing Date 11
, Jan
, January
is for months, 02
, Mon
, Monday
for Day of the month, 2006
for year and of course MST
for zone
But you can use this layout as well, which I find very simple. "Mon Jan 2 15:04:05 MST 2006"
const layout = "Mon Jan 2 15:04:05 MST 2006"
userTimeString := "Fri Dec 6 13:05:05 CET 2019"
t, _ := time.Parse(layout, userTimeString)
fmt.Println("Server: ", t.Format(time.RFC850))
//Server: Friday, 06-Dec-19 13:05:05 CET
mumbai, _ := time.LoadLocation("Asia/Kolkata")
mumbaiTime := t.In(mumbai)
fmt.Println("Mumbai: ", mumbaiTime.Format(time.RFC850))
//Mumbai: Friday, 06-Dec-19 18:35:05 IST
Equality in direct comparing:
string1 = "sample"
string2 = "sample"
if string1 == string2 :
print("Strings are equal with text : ", string1," & " ,string2)
else :
print ("Strings are not equal")
Equality in character sets:
string1 = 'abc def ghi'
string2 = 'def ghi abc'
set1 = set(string1.split(' '))
set2 = set(string2.split(' '))
print set1 == set2
if string1 == string2 :
print("Strings are equal with text : ", string1," & " ,string2)
else :
print ("Strings are not equal")
Not All Components.
the state
in component looks like the source of the waterfall of state of the whole APP.
So the change happens from where the setState called. The tree of renders
then get called from there. If you've used pure component, the render
will be skipped.
As Suhel Meman said in the comments:
SELECT column1, column2, column3 FROM table 1
UNION
SELECT column1, column2, column3 FROM table 2
...
would work.
But all your SELECTS
would have to consist of the same amount of columns. And because you are displaying it in one resulting table they should contain the same information.
What you might want to do, is a JOIN on Product ID or something like that. This way you would get more columns, which makes more sense most of the time.
I found the cleanest way of doing it is this.
Tested on Django 3.1.5
class MyForm(forms.Form):
my_boolean = forms.BooleanField(required=False, initial=True)
ResultSet rs = ps.executeQuery();
int rowcount = 0;
if (rs.last()) {
rowcount = rs.getRow();
rs.beforeFirst(); // not rs.first() because the rs.next() below will move on, missing the first element
}
while (rs.next()) {
// do your standard per row stuff
}
I suggest you to use ArgueJS this way:
function myFunc(){
arguments = __({requiredArg: undefined, optionalArg: [undefined: 'defaultValue'})
//do stuff, using arguments.requiredArg and arguments.optionalArg
// to access your arguments
}
You can also replace undefined
by the type of the argument you expect to receive, like this:
function myFunc(){
arguments = __({requiredArg: Number, optionalArg: [String: 'defaultValue'})
//do stuff, using arguments.requiredArg and arguments.optionalArg
// to access your arguments
}
You concrete problem is caused because you're mixing discouraged and old school scriptlets <% %>
with its successor EL ${}
. They do not share the same variable scope. The allFestivals
is not available in scriptlet scope and the i
is not available in EL scope.
You should install JSTL (<-- click the link for instructions) and declare it in top of JSP as follows:
<%@taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core"%>
and then iterate over the list as follows:
<c:forEach items="${allFestivals}" var="festival">
<tr>
<td>${festival.festivalName}</td>
<td>${festival.location}</td>
<td>${festival.startDate}</td>
<td>${festival.endDate}</td>
<td>${festival.URL}</td>
</tr>
</c:forEach>
(beware of possible XSS attack holes, use <c:out>
accordingly)
Don't forget to remove the <jsp:useBean>
as it has no utter value here when you're using a servlet as model-and-view controller. It would only lead to confusion. See also our servlets wiki page. Further you would do yourself a favour to disable scriptlets by the following entry in web.xml
so that you won't accidently use them:
<jsp-config>
<jsp-property-group>
<url-pattern>*.jsp</url-pattern>
<scripting-invalid>true</scripting-invalid>
</jsp-property-group>
</jsp-config>

If you need a function that behaves as a nop, try
nop = lambda *a, **k: None
nop()
Sometimes I do stuff like this when I'm making dependencies optional:
try:
import foo
bar=foo.bar
baz=foo.baz
except:
bar=nop
baz=nop
# Doesn't break when foo is missing:
bar()
baz()
There are a couple ways.
ImageConverter
public static byte[] ImageToByte(Image img)
{
ImageConverter converter = new ImageConverter();
return (byte[])converter.ConvertTo(img, typeof(byte[]));
}
This one is convenient because it doesn't require a lot of code.
Memory Stream
public static byte[] ImageToByte2(Image img)
{
using (var stream = new MemoryStream())
{
img.Save(stream, System.Drawing.Imaging.ImageFormat.Png);
return stream.ToArray();
}
}
This one is equivalent to what you are doing, except the file is saved to memory instead of to disk. Although more code you have the option of ImageFormat and it can be easily modified between saving to memory or disk.

From the article:
XPathDocument myXPathDoc = new XPathDocument(myXmlFile) ;
XslTransform myXslTrans = new XslTransform() ;
myXslTrans.Load(myStyleSheet);
XmlTextWriter myWriter = new XmlTextWriter("result.html",null) ;
myXslTrans.Transform(myXPathDoc,null,myWriter) ;
Edit:
But my trusty compiler says, XslTransform
is obsolete: Use XslCompiledTransform
instead:
XPathDocument myXPathDoc = new XPathDocument(myXmlFile) ;
XslCompiledTransform myXslTrans = new XslCompiledTransform();
myXslTrans.Load(myStyleSheet);
XmlTextWriter myWriter = new XmlTextWriter("result.html",null);
myXslTrans.Transform(myXPathDoc,null,myWriter);
Since the request
module that other answers use has been deprecated, may I suggest switching to node-fetch
:
const fetch = require("node-fetch")
const url = "https://www.googleapis.com/urlshortener/v1/url"
const payload = { longUrl: "http://www.google.com/" }
const res = await fetch(url, {
method: "post",
body: JSON.stringify(payload),
headers: { "Content-Type": "application/json" },
})
const { id } = await res.json()
It's time to check the latest release/s for Visual Studio, folks. The most suggested solution that did not work for some of you before might work now.
In Visual Studio 2017 (Release Version 15.4.2 and above), going to Tools > Options > Debugging > General > (Check Box) Redirect all Output Window text to Immediate Window
has worked for me.
Few Notes:
Best wishes!
There is apex_util.string_to_table
- see my answer to this question.
Also, prior to the existence of the above function, I once posted a solution here on my blog.
In later versions of APEX, apex_util.string_to_table
is deprecated, and a similar function apex_string.split is preferred.
SELECT id,
Group_concat(column
)
FROM (SELECT id,
Concat(name
, ':', Group_concat(value
)) AS column
FROM mytbl
GROUP BY id,
name) tbl
GROUP BY id;
One approach: if you can guarantee unrelated applications won't use the files in a conflicting manner, just create a pool of files of varying sizes in a specific directory, then create links to them when needed.
For example, have a pool of files called:
Then, if you have an application that needs a 1G file called /home/oracle/logfile, execute a "ln /home/bigfiles/1024M-A /home/oracle/logfile
".
If it's on a separate filesystem, you will have to use a symbolic link.
The A/B/etc files can be used to ensure there's no conflicting use between unrelated applications.
The link operation is about as fast as you can get.
An independent parent is the best practice for sharing configuration and options across otherwise uncoupled components. Apache has a parent pom project to share legal notices and some common packaging options.
If your top-level project has real work in it, such as aggregating javadoc or packaging a release, then you will have conflicts between the settings needed to do that work and the settings you want to share out via parent. A parent-only project avoids that.
A common pattern (ignoring #1 for the moment) is have the projects-with-code use a parent project as their parent, and have it use the top-level as a parent. This allows core things to be shared by all, but avoids the problem described in #2.
The site plugin will get very confused if the parent structure is not the same as the directory structure. If you want to build an aggregate site, you'll need to do some fiddling to get around this.
Apache CXF is an example the pattern in #2.
You'll need to either insert BR
tag appropriately in the resulting string, or use for example a PRE
tag so that the formatting of the stringify
is retained:
var data = { a: 1, b: 2 };
var Hello = React.createClass({
render: function() {
return <div><pre>{JSON.stringify(data, null, 2) }</pre></div>;
}
});
React.render(<Hello />, document.getElementById('container'));
class PrettyPrintJson extends React.Component {
render() {
// data could be a prop for example
// const { data } = this.props;
return (<div><pre>{JSON.stringify(data, null, 2) }</pre></div>);
}
}
ReactDOM.render(<PrettyPrintJson/>, document.getElementById('container'));
const PrettyPrintJson = ({data}) => {
// (destructured) data could be a prop for example
return (<div><pre>{ JSON.stringify(data, null, 2) }</pre></div>);
}
Or, ...
const PrettyPrintJson = ({data}) => (<div><pre>{
JSON.stringify(data, null, 2) }</pre></div>);
(You might even want to use a memo, 16.6+)
const PrettyPrintJson = React.memo(({data}) => (<div><pre>{
JSON.stringify(data, null, 2) }</pre></div>));
You can use the top margin-top and adjust the text or you could also use padding-top both would have similar visual effect in your case but actually both behave a bit differently.
I created a small component that handles this for you: react-toggle-display
It sets the style attribute to display: none !important
based on the hide
or show
props.
Example usage:
var ToggleDisplay = require('react-toggle-display');
var Search = React.createClass({
getInitialState: function() {
return { showResults: false };
},
onClick: function() {
this.setState({ showResults: true });
},
render: function() {
return (
<div>
<input type="submit" value="Search" onClick={this.onClick} />
<ToggleDisplay show={this.state.showResults}>
<Results />
</ToggleDisplay>
</div>
);
}
});
var Results = React.createClass({
render: function() {
return (
<div id="results" className="search-results">
Some Results
</div>
);
}
});
React.renderComponent(<Search />, document.body);
Requests doesn't have an equivalent to Urlib2's read()
.
>>> import requests
>>> response = requests.get("http://www.google.com")
>>> print response.content
'<!doctype html><html itemscope="" itemtype="http://schema.org/WebPage"><head>....'
>>> print response.content == response.text
True
It looks like the POST request you are making is returning no content. Which is often the case with a POST request. Perhaps it set a cookie? The status code is telling you that the POST succeeded after all.
Edit for Python 3:
Python now handles data types differently. response.content
returns a sequence of bytes
(integers that represent ASCII) while response.text
is a string
(sequence of chars).
Thus,
>>> print response.content == response.text
False
>>> print str(response.content) == response.text
True
The previously mentioned solutions work well with chrome but not on Firefox.
I found a Solution that works well both in Chrome and Firefox(not on IE). Add the following attributes to the CSS for your SELECTelement and adjust the margin-top to suit your needs.
select {
-webkit-appearance: none;
-moz-appearance: none;
text-indent: 1px;
text-overflow: '';
}
Hope this helps :)
Old style using ResultSet
@Transactional(readOnly=true)
public void accessUser() {
EntityManager em = this.getEntityManager();
org.hibernate.Session session = em.unwrap(org.hibernate.Session.class);
session.doWork(new Work() {
@Override
public void execute(Connection con) throws SQLException {
try (PreparedStatement stmt = con.prepareStatement(
"SELECT u.username, u.name, u.email, 'blabla' as passe, login_type as loginType FROM users u")) {
ResultSet rs = stmt.executeQuery();
ResultSetMetaData rsmd = rs.getMetaData();
for (int i = 1; i <= rsmd.getColumnCount(); i++) {
System.out.print(rsmd.getColumnName(i) + " (" + rsmd.getColumnTypeName(i) + ") / ");
}
System.out.println("");
while (rs.next()) {
System.out.println("Found username " + rs.getString("USERNAME") + " name " + rs.getString("NAME") + " email " + rs.getString("EMAIL") + " passe " + rs.getString("PASSE") + " email " + rs.getInt("LOGIN_TYPE"));
}
}
}
});
}
Here's something I did to change the headers on a tab-delimited file. I'm omitting the part where I only edited the first line of the file. You could adapt it to Python pretty easily with the re library. This also includes separating out numbers (but keeps the digits together). I did it in two steps because that was easier than telling it not to put an underscore at the start of a line or tab.
Step One...find uppercase letters or integers preceded by lowercase letters, and precede them with an underscore:
Search:
([a-z]+)([A-Z]|[0-9]+)
Replacement:
\1_\l\2/
Step Two...take the above and run it again to convert all caps to lowercase:
Search:
([A-Z])
Replacement (that's backslash, lowercase L, backslash, one):
\l\1
if anyone has a problem on Mac, can try this
sudo pip install --upgrade matplotlib --ignore-installed six
I needed to show the string in UI as well as save that to an xml configuration file. The above specified format is good for string in c++, I would add we can have the xml compatible string for the special character by replacing "\u" by "&#x" and adding a ";" at the end.
For example :
C++ : "\u0444" --> XML : "ф"
If you want to make it clear what each initializer value is, just split it up on multiple lines, with a comment on each:
address temp_addres = {
0, // street_no
nullptr, // street_name
"Hamilton", // city
"Ontario", // prov
nullptr, // postal_code
};
