In short, services set to Automatic will start during the boot process, while services set to start as Delayed will start shortly after boot.
Starting your service Delayed improves the boot performance of your server and has security benefits which are outlined in the article Adriano linked to in the comments.
Update: "shortly after boot" is actually 2 minutes after the last "automatic" service has started, by default. This can be configured by a registry key, according to Windows Internals and other sources (3,4).
The registry keys of interest (At least in some versions of windows) are:
HKLM\SYSTEM\CurrentControlSet\services\<service name>\DelayedAutostart
will have the value 1
if delayed, 0
if not.HKLM\SYSTEM\CurrentControlSet\services\AutoStartDelay
or HKLM\SYSTEM\CurrentControlSet\Control\AutoStartDelay
(on Windows 10): decimal number of seconds to wait, may need to create this one. Applies globally to all Delayed services.Powershell handles tasks like this fairly handily:
$productCode = (gwmi win32_product | `
? { $_.Name -Like "<PRODUCT NAME HERE>*" } | `
% { $_.IdentifyingNumber } | `
Select-Object -First 1)
You can then use it to get the uninstall information as well:
$wow = ""
$is32BitInstaller = $True # or $False
if($is32BitInstaller -and [System.Environment]::Is64BitOperatingSystem)
{
$wow = "\Wow6432Node"
}
$regPath = "HKEY_LOCAL_MACHINE\SOFTWARE$wow\Microsoft\Windows\CurrentVersion\Uninstall"
dir "HKLM:\SOFTWARE$wow\Microsoft\Windows\CurrentVersion\Uninstall" | `
? { $_.Name -Like "$regPath\$productCode" }
Launch the installer, but don't press the Install > button. Then
cd "%AppData%\..\LocalLow\Sun\Java"
and find your MSI file in one of sub-directories (e.g., jre1.7.0_25
).
Note that Data1.cab
from that sub-directory will be required as well.
I've solved this issue by directly editing the byte array. Collect the UTF8 preamble and remove directly the header. Afterward you can transform the byte[]to a string with GetString method, see below. The \r and \t I've removed as well, just as precaution.
XmlDocument configurationXML = new XmlDocument();
List<byte> byteArray = new List<byte>(webRequest.downloadHandler.data);
foreach(byte singleByte in Encoding.UTF8.GetPreamble())
{
byteArray.RemoveAt(byteArray.IndexOf(singleByte));
}
string xml = System.Text.Encoding.UTF8.GetString(byteArray.ToArray());
xml = xml.Replace("\\r", "");
xml = xml.Replace("\\t", "");
The proper way to install an MSI silently is via the msiexec.exe command line
as follows:
msiexec.exe /i c:\setup.msi /QN /L*V "C:\Temp\msilog.log"
Quick explanation:
/L*V "C:\Temp\msilog.log"= verbose logging
/QN = run completely silently
/i = run install sequence
There is a much more comprehensive answer here: Batch script to install MSI. This answer provides details on the msiexec.exe command line options and a description of how to find the "public properties" that you can set on the command line at install time. These properties are generally different for each MSI.
Below worked for me.
<Product Id="*" Name="XXXInstaller" Language="1033" Version="1.0.0.0"
Manufacturer="XXXX" UpgradeCode="YOUR_GUID_HERE">
<Package InstallerVersion="xxx" Compressed="yes"/>
<Upgrade Id="YOUR_GUID_HERE">
<UpgradeVersion Property="REMOVINGTHEOLDVERSION" Minimum="1.0.0.0"
RemoveFeatures="ALL" />
</Upgrade>
<InstallExecuteSequence>
<RemoveExistingProducts After="InstallInitialize" />
</InstallExecuteSequence>
Please make sure that the UpgradeCode in Product is matching to Id in Upgrade.
There is also a very helpful GUI tool called Product Browser which appears to be made by Microsoft or at least an employee of Microsoft.
It can be found on Github here Product Browser
I personally had a very easy time locating the GUID I needed with this.
There are multiple problems with yaluna's answer, also property names are case sensitive, Installed
is the correct spelling (INSTALLED
will not work).
The table above should've been this:
Also assuming a full repair & uninstall the actual values of properties could be:
The WiX Expression Syntax documentation says:
In these expressions, you can use property names (remember that they are case sensitive).
The properties are documented at the Windows Installer Guide (e.g. Installed)
EDIT: Small correction to the first table; evidently "Uninstall" can also happen with just REMOVE
being True
.
Set the DISABLEADVTSHORTCUTS
property to force all advertised shortcuts in your installer to become regular shortcuts, and you don't need to include a dummy reg key to be used as the keypath.
<Property Id="DISABLEADVTSHORTCUTS" Value="1"/>
I think Windows Installer 4.0 or higher is a requirement.
you need /q at the end
MsiExec.exe /x {2F808931-D235-4FC7-90CD-F8A890C97B2F} /q
You need to enclose multiple conditions in braces due to operator precedence and use the bitwise and (&
) and or (|
) operators:
foo = df[(df['column1']==value) | (df['columns2'] == 'b') | (df['column3'] == 'c')]
If you use and
or or
, then pandas is likely to moan that the comparison is ambiguous. In that case, it is unclear whether we are comparing every value in a series in the condition, and what does it mean if only 1 or all but 1 match the condition. That is why you should use the bitwise operators or the numpy np.all
or np.any
to specify the matching criteria.
There is also the query method: http://pandas.pydata.org/pandas-docs/dev/generated/pandas.DataFrame.query.html
but there are some limitations mainly to do with issues where there could be ambiguity between column names and index values.
Using java.nio.Files along with java.nio.file.StandardOpenOption
PrintWriter out = null;
BufferedWriter bufWriter;
try{
bufWriter =
Files.newBufferedWriter(
Paths.get("log.txt"),
Charset.forName("UTF8"),
StandardOpenOption.WRITE,
StandardOpenOption.APPEND,
StandardOpenOption.CREATE);
out = new PrintWriter(bufWriter, true);
}catch(IOException e){
//Oh, no! Failed to create PrintWriter
}
//After successful creation of PrintWriter
out.println("Text to be appended");
//After done writing, remember to close!
out.close();
This creates a BufferedWriter
using Files, which accepts StandardOpenOption
parameters, and an auto-flushing PrintWriter
from the resultant BufferedWriter
. PrintWriter
's println()
method, can then be called to write to the file.
The StandardOpenOption
parameters used in this code: opens the file for writing, only appends to the file, and creates the file if it does not exist.
Paths.get("path here")
can be replaced with new File("path here").toPath()
.
And Charset.forName("charset name")
can be modified to accommodate the desired Charset
.
You can handle it in different ways,
Objective is to check if the div exist then execute the code. Simple.
Condition:
$('#myDiv').length
Note:
#myDiv -> < div id='myDiv' > <br>
.myDiv -> < div class='myDiv' >
This will return a number every time it is executed so if there is no div it will give a Zero [0], and as we no 0 can be represented as false in binary so you can use it in if statement. And you can you use it as a comparison with a none number. while any there are three statement given below
// Statement 0
// jQuery/Ajax has replace [ document.getElementById with $ sign ] and etc
// if you don't want to use jQuery/ajax
if (document.getElementById(name)) {
$("div#page-content div#chatbar").append("<div class='labels'>" + name + "</div><div id='" + name + "'></div>");
}
// Statement 1
if ($('#'+ name).length){ // if 0 then false ; if not 0 then true
$("div#page-content div#chatbar").append("<div class='labels'>" + name + "</div><div id='" + name + "'></div>");
}
// Statement 2
if(!$('#'+ name).length){ // ! Means Not. So if it 0 not then [0 not is 1]
$("div#page-content div#chatbar").append("<div class='labels'>" + name + "</div><div id='" + name + "'></div>");
}
// Statement 3
if ($('#'+ name).length > 0 ) {
$("div#page-content div#chatbar").append("<div class='labels'>" + name + "</div><div id='" + name + "'></div>");
}
// Statement 4
if ($('#'+ name).length !== 0 ) { // length not equal to 0 which mean exist.
$("div#page-content div#chatbar").append("<div class='labels'>" + name + "</div><div id='" + name + "'></div>");
}
With Visual Studio Code 1.27.2:
When I go to File > Preference > Settings, I get the following tab
I type rulers in Search settings and I get the following list of settings
Clicking on the first Edit in settings.json, I can edit the user settings
Clicking on the pen icon that appears to the left of the setting in Default user settings I can copy it on the user settings and edit it
With Visual Studio Code 1.38.1, the screenshot shown on the third point changes to the following one.
The panel for selecting the default user setting values isn't shown anymore.
I think the following offers a slightly different approach... compare fn_fast_fail()
with fn_slow_fail()
... though the latter doesn't fail as such... you can check if one or both of a
and b
is an instance of Error
and throw
that Error
if you want it to reach the catch
block (e.g. if (b instanceof Error) { throw b; }
) . See the jsfiddle.
var p1 = new Promise((resolve, reject) => {
setTimeout(() => resolve('p1_delayed_resolvement'), 2000);
});
var p2 = new Promise((resolve, reject) => {
reject(new Error('p2_immediate_rejection'));
});
var fn_fast_fail = async function () {
try {
var [a, b] = await Promise.all([p1, p2]);
console.log(a); // "p1_delayed_resolvement"
console.log(b); // "Error: p2_immediate_rejection"
} catch (err) {
console.log('ERROR:', err);
}
}
var fn_slow_fail = async function () {
try {
var [a, b] = await Promise.all([
p1.catch(error => { return error }),
p2.catch(error => { return error })
]);
console.log(a); // "p1_delayed_resolvement"
console.log(b); // "Error: p2_immediate_rejection"
} catch (err) {
// we don't reach here unless you throw the error from the `try` block
console.log('ERROR:', err);
}
}
fn_fast_fail(); // fails immediately
fn_slow_fail(); // waits for delayed promise to resolve
This is an improvement over @Mottie's answer because as of jQuery 1.5.2 :text
selects input
elements that have no specified type
attribute (in which case type="text"
is implied):
$('form').find(':text,textarea,select').filter(':visible:first')
diff --color
option was added to GNU diffutils 3.4 (2016-08-08)
This is the default diff
implementation on most distros, which will soon be getting it.
Ubuntu 18.04 has diffutils
3.6 and therefore has it.
On 3.5 it looks like this:
Tested with:
diff --color -u \
<(seq 6 | sed 's/$/ a/') \
<(seq 8 | grep -Ev '^(2|3)$' | sed 's/$/ a/')
Apparently added in commit c0fa19fe92da71404f809aafb5f51cfd99b1bee2 (Mar 2015).

Git integration
ydiff
integrates with Git without any configuration required.
From inside a git repository, instead of git diff
, you can do just:
ydiff -s
and instead of git log
:
ydiff -ls
See also: How can I get a side-by-side diff when I do "git diff"?
Tested on Ubuntu 16.04, git 2.18.0, ydiff 1.1.
Per batch, 65536 * Network Packet Size which is 4k so 256 MB
However, IN will stop way before that but it's not precise.
You end up with memory errors but I can't recall the exact error. A huge IN will be inefficient anyway.
Edit: Remus reminded me: the error is about "stack size"
A good place to start your investigation into any failed binding is to use the "fuslogvw.exe" utility. This may give you the information you need related to the binding failure so that you don't have to go messing around with any registry values to turn binding logging on.
The utility should be in your Microsoft SDKs folder, which would be something like this, depending on your operating system: "C:\Program Files (x86)\Microsoft SDKs\Windows\v{SDK version}A\Bin\FUSLOGVW.exe"
Run this utility as Administrator, from Developer Command Prompt (as Admin) type FUSLOGVW
a new screen appears
Go to Settings to and select Enable all binds to disk also select Enable custom log path and select the path of the folder of your choice to store the binding log.
Restart IIS.
From the FUSLOGVW window click Delete all to clear the list of any previous bind failures
Reproduce the binding failure in your application
In the utility, click Refresh. You should then see the bind failure logged in the list.
You can view information about the bind failure by selecting it in the list and clicking View Log
The first thing I look for is the path in which the application is looking for the assembly. You should also make sure the version number of the assembly in question is what you expect.
Assuming your json object from your GET request looks like the one you posted above simply do:
let list: string[] = [];
json.Results.forEach(element => {
list.push(element.Id);
});
Or am I missing something that prevents you from doing it this way?
you might want to look at the online version of xsv
Note: this is JQuery. See Sébastien answer for Javascript
$(function() {
var temp="a";
$("#MySelect").val(temp);
});
<select name="MySelect" id="MySelect">
<option value="a">a</option>
<option value="b">b</option>
<option value="c">c</option>
</select>
It is possible to use the host_name() function
select HOST_NAME()
Here's another solution that's in the spirit of the one given by @naught101, but simpler and also does not throw a warning on the latest version of ggplot2.
Basically, you first create a named character vector
hospital_names <- c(
`Hospital#1` = "Some Hospital",
`Hospital#2` = "Another Hospital",
`Hospital#3` = "Hospital Number 3",
`Hospital#4` = "The Other Hospital"
)
And then you use it as a labeller, just by modifying the last line of the code given by @naught101 to
... + facet_grid(hospital ~ ., labeller = as_labeller(hospital_names))
Hope this helps.
For sorting by multiple criteria, namely for instance by the second and third elements in a tuple, let
data = [(1,2,3),(1,2,1),(1,1,4)]
and so define a lambda that returns a tuple that describes priority, for instance
sorted(data, key=lambda tup: (tup[1],tup[2]) )
[(1, 1, 4), (1, 2, 1), (1, 2, 3)]
GUID is Microsoft's implementation of the UUID standard.
Per Wikipedia:
The term GUID usually refers to Microsoft's implementation of the Universally Unique Identifier (UUID) standard.
An updated quote from that same Wikipedia article:
RFC 4122 itself states that UUIDs "are also known as GUIDs". All this suggests that "GUID", while originally referring to a variant of UUID used by Microsoft, has become simply an alternative name for UUID…
For me the following work-around worked:
Here the code:
def split_up_resize(arr, res):
"""
function which resizes large array (direct resize yields error (addedtypo))
"""
# compute destination resolution for subarrays
res_1 = (res[0], res[1]/2)
res_2 = (res[0], res[1] - res[1]/2)
# get sub-arrays
arr_1 = arr[0 : len(arr)/2]
arr_2 = arr[len(arr)/2 :]
# resize sub arrays
arr_1 = cv2.resize(arr_1, res_1, interpolation = cv2.INTER_LINEAR)
arr_2 = cv2.resize(arr_2, res_2, interpolation = cv2.INTER_LINEAR)
# init resized array
arr = np.zeros((res[1], res[0]))
# merge resized sub arrays
arr[0 : len(arr)/2] = arr_1
arr[len(arr)/2 :] = arr_2
return arr
public static ArrayList<Integer> duplicate(final int[] zipcodelist) {
HashSet<Integer> hs = new HashSet<>();
ArrayList<Integer> al = new ArrayList<>();
for(int element: zipcodelist) {
if(hs.add(element)==false) {
al.add(element);
}
}
return al;
}
I know this is a little late, nevertheless i'm answering this for anyone still experiencing this issue on windows (USING XAMPP).
Step 1. Verify that there is a mismatch in your PHP version. To do this, open routes/web.php and create a simple route to return the php information like so:
Route::get('/', function() {
return response()->json([
'stuff' => phpinfo()
]);
})
and compare this with output from your command line
As we can see, in my case there is a mismatch, this usually happens if you have multiple versions of php installed.
Step 2. Add the php version being used by your xampp to your system path
Step 3. Verify that you have the extension enabled in your php.ini file. NB. Make sure you are editing the php.ini file that is shown under the 'loaded configuration file' entry in the results of phpinfo() command.
[
and subset are not substitutable:
[
does return a vector if only one column is selected.
df = data.frame(a="a",b="b")
identical(
df[,c("a")],
subset(df,select="a")
)
identical(
df[,c("a","b")],
subset(df,select=c("a","b"))
)
You have to use the Print to a New PDF option using the PDF printer. Once in the dialog box, set the page scaling to 100% and set your page size. Once you do that, your new PDF will be uniform in page sizes.
there are some mistakes in your code - the first: you havn't closed you p
-tag:
<a href="http//www.google.com"><p style="text-align:center">Search</p></a>
next: p
stands for 'paragraph' and is a block-element (so it's causing a line-break). what you wanted to use there is a span
, wich is just an inline-element for formatting:
<a href="http//www.google.com"><span style="text-align:center">Search</span></a>
but if you just want to add a style to your link, why don't you set the style for that link directly:
<a href="http//www.google.com" style="text-align:center">Search</a>
in the end, this would at least be correct html, but still not exactly what you want, because text-align:center
centers the text in that element, so you would have to set that for the element that contains this links (this piece of html isn't posted, so i can't correct you, but i hope you understand) - to show this, i'll use a simple div
:
<div style="text-align:center">
<a href="http//www.google.com">Search</a>
<!-- more links here -->
</div>
EDIT: some more additions to your question:
p
is not a 'function', but you're right, this is causing the problem (because it's a block-element)I understand that the Q does not want to use a library, but I will offer this for others coming from Google searches. @EricRowell mentioned a good plugin, but, there is also another plugin you can try, html2canvas.
In our case we are using layered transparent PNG's with z-index
as a "product builder" widget. Html2canvas worked brilliantly to boil the stack down without pushing images, nor using complexities, workarounds, and the "non-responsive" canvas itself. We were not able to do this smoothly/sane with the vanilla canvas+JS.
First use z-index
on absolute divs to generate layered content within a relative positioned wrapper. Then pipe the wrapper through html2canvas to get a rendered canvas, which you may leave as-is, or output as an image so that a client may save it.
I'm not sure what happened in your case that fixed the issue, but your issue was on this line:
Caused by: java.lang.NoClassDefFoundError: javax/xml/rpc/handler/soap/SOAPMessageContext
You need to add jaxrpc-api.jar
to your /lib
s or add
<dependency>
<groupId>javax.xml</groupId>
<artifactId>jaxrpc-api</artifactId>
<version>x.x.x</version>
</dependency>
to your maven dependencies.
Never mind, I found the answer.
This will do the trick.
Dim colIndex As Long
colIndex = Application.Match(colName, Range(Cells(rowIndex, 1), Cells(rowIndex, 100)), 0)
PROBLEM RESOLVED
In my case the problem was that I do the ajax call (with $.ajax, $.get or $.getJSON methods from jQuery) with full path in the url param:
But the correct way is to pass the value of url as:
url: "site/cgi-bin/serverApp.php"
Some browser don't conflict and make no distiction between one text or another, but in Firefox 3.6 for Mac OS take this full path as "cross site scripting"... another thing, in the same browser there is a distinction between:
http://mydomain.com/site/index.html
And put
http://www.mydomain.com/site/index.html
In fact it is the correct point view, but most implementations make no distinction, so the solution was to remove all the text that specify the full path to the script in the methods that do the ajax request AND.... remove any BASE tag in the index.html file
base href="http://mydomain.com/" <--- bad idea, remove it!
If you don't remove it, this version of browser for this system may take your ajax request like if it is a cross site request!
I have the same problem but only on the Mac OS machine. The problem is that Firefox treat the ajax response as an "cross site" call, in any other machine/browser it works fine. I didn't found any help about this (I think that is a firefox implementation issue), but I'm going to prove the next code at the server side:
header('Content-type: application/json');
to ensure that browser get the data as "json data" ...
Not for the questioner, but for all others, which are interested: See: How to define Typescript Map of key value pair. where key is a number and value is an array of objects
The solution is therefore:
let yourVar: Map<YourKeyType, YourValueType>;
// now you can use it:
yourVar = new Map<YourKeyType, YourValueType>();
yourVar[YourKeyType] = <YourValueType> yourValue;
Cheers!
There is another working example with some my comments :
List<MimePart> mimeParts = new List<MimePart>();
try
{
foreach (string key in form.AllKeys)
{
StringMimePart part = new StringMimePart();
part.Headers["Content-Disposition"] = "form-data; name=\"" + key + "\"";
part.StringData = form[key];
mimeParts.Add(part);
}
int nameIndex = 0;
foreach (UploadFile file in files)
{
StreamMimePart part = new StreamMimePart();
if (string.IsNullOrEmpty(file.FieldName))
file.FieldName = "file" + nameIndex++;
part.Headers["Content-Disposition"] = "form-data; name=\"" + file.FieldName + "\"; filename=\"" + file.FileName + "\"";
part.Headers["Content-Type"] = file.ContentType;
part.SetStream(file.Data);
mimeParts.Add(part);
}
string boundary = "----------" + DateTime.Now.Ticks.ToString("x");
req.ContentType = "multipart/form-data; boundary=" + boundary;
req.Method = "POST";
long contentLength = 0;
byte[] _footer = Encoding.UTF8.GetBytes("--" + boundary + "--\r\n");
foreach (MimePart part in mimeParts)
{
contentLength += part.GenerateHeaderFooterData(boundary);
}
req.ContentLength = contentLength + _footer.Length;
byte[] buffer = new byte[8192];
byte[] afterFile = Encoding.UTF8.GetBytes("\r\n");
int read;
using (Stream s = req.GetRequestStream())
{
foreach (MimePart part in mimeParts)
{
s.Write(part.Header, 0, part.Header.Length);
while ((read = part.Data.Read(buffer, 0, buffer.Length)) > 0)
s.Write(buffer, 0, read);
part.Data.Dispose();
s.Write(afterFile, 0, afterFile.Length);
}
s.Write(_footer, 0, _footer.Length);
}
return (HttpWebResponse)req.GetResponse();
}
catch
{
foreach (MimePart part in mimeParts)
if (part.Data != null)
part.Data.Dispose();
throw;
}
And there is example of using :
UploadFile[] files = new UploadFile[]
{
new UploadFile(@"C:\2.jpg","new_file","image/jpeg") //new_file is id of upload field
};
NameValueCollection form = new NameValueCollection();
form["id_hidden_input"] = "value_hidden_inpu"; //there is additional param (hidden fields on page)
HttpWebRequest req = (HttpWebRequest)WebRequest.Create(full URL of action);
// set credentials/cookies etc.
req.CookieContainer = hrm.CookieContainer; //hrm is my class. i copied all cookies from last request to current (for auth)
HttpWebResponse resp = HttpUploadHelper.Upload(req, files, form);
using (Stream s = resp.GetResponseStream())
using (StreamReader sr = new StreamReader(s))
{
string response = sr.ReadToEnd();
}
//profit!

If you're on Linux, or have cygwin available on Windows, you can run the input XML through a simple sed script that will replace <Active>True</Active>
with <Active>true</Active>
, like so:
cat <your XML file> | sed 'sX<Active>True</Active>X<Active>true</Active>X' | xmllint --schema -
If you're not, you can still use a non-validating xslt pocessor (xalan, saxon etc.) to run a simple xslt transformation on the input, and only then pipe it to xmllint.
What the xsl should contain something like below, for the example you listed above (the xslt processor should be 2.0 capable):
<?xml version="1.0"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="2.0">
<xsl:output method="xml" indent="yes"/>
<xsl:template match="/">
<xsl:for-each select="XML">
<xsl:for-each select="Active">
<xsl:value-of select=" replace(current(), 'True','true')"/>
</xsl:for-each>
</xsl:for-each>
</xsl:template>
</xsl:stylesheet>
A Bash function can't return a string directly like you want it to. You can do three things:

A solution that works:
Wrap the part of the document that needs this modified behavior with the code provided below. In my case the portion to wrap is a \part{} and some text following it.
\makeatletter\@openrightfalse
\part{Whatever}
Some text
\chapter{Foo}
\@openrighttrue\makeatother
The wrapped portion should also include the chapter at the beginning of which this behavior needs to stop. Otherwise LaTeX may generate an empty page before this chapter.

Eclipse has limit of 32000 characters per line. If you have, for example JSONObject, which you want to log into console, you won't succeed. You can't handle this with the checkbox. Tested
There's obviously more than one way to do it, but I would suggest using the more standard:
ErrorDocument 404 /index.php?page=404
Just if someone is having this issue and hadn't done list[index, sub-index]
, you could be having the problem because you're missing a comma between two arrays in an array of arrays (It happened to me).
String
objects in Java use the UTF-16 encoding that can't be modified.
The only thing that can have a different encoding is a byte[]
. So if you need UTF-8 data, then you need a byte[]
. If you have a String
that contains unexpected data, then the problem is at some earlier place that incorrectly converted some binary data to a String
(i.e. it was using the wrong encoding).
Does the --lock-tables=false
option work?
According to the man page, if you are dumping InnoDB tables you can use the --single-transaction
option:
--lock-tables, -l
Lock all tables before dumping them. The tables are locked with READ
LOCAL to allow concurrent inserts in the case of MyISAM tables. For
transactional tables such as InnoDB and BDB, --single-transaction is
a much better option, because it does not need to lock the tables at
all.
For innodb DB:
mysqldump --single-transaction=TRUE -u username -p DB
This is an adaptation from my code for you. I was inspired from developpez.com (Look in the page for : "Pour insérer des données, vaut-il mieux passer par un RecordSet ou par une requête de type INSERT ?"). They explain (with a little French). This way is much faster than the one upper. In the example, this way was 37 times faster. Try it.
Const tableName As String = "InvoiceNumbers"
Const columnIdName As String = "??"
Const columnDateName As String = "date"
Dim rsTable As DAO.recordSet
Dim recordId as long
Set rsTable = CurrentDb.OpenRecordset(tableName)
Call rsTable .AddNew
recordId = CLng(rsTable (columnIdName)) ' Save your Id in a variable
rsTable (columnDateName) = Now() ' Store your data
rsTable .Update
recordSet.Close

use \\:
instead of \:
.. the \
has special meaning in java strings.
return filename.replace(/\.([a-zA-Z0-9]+)$/, "$1");
edit: Strangely (or maybe it's not) the $1
in the second argument of the replace method doesn't seem to work... Sorry.
Saish's answer using REGEXP_LIKE
is the right idea but does not support floating numbers. This one will ...
Return values that are numeric
SELECT foo
FROM bar
WHERE REGEXP_LIKE (foo,'^-?\d+(\.\d+)?$');
Return values not numeric
SELECT foo
FROM bar
WHERE NOT REGEXP_LIKE (foo,'^-?\d+(\.\d+)?$');
You can test your regular expressions themselves till your heart is content at http://regexpal.com/ (but make sure you select the checkbox match at line breaks for this one).
Two options:
for (let item in MotifIntervention) {
if (isNaN(Number(item))) {
console.log(item);
}
}
Or
Object.keys(MotifIntervention).filter(key => !isNaN(Number(MotifIntervention[key])));
String enums look different than regular ones, for example:
enum MyEnum {
A = "a",
B = "b",
C = "c"
}
Compiles into:
var MyEnum;
(function (MyEnum) {
MyEnum["A"] = "a";
MyEnum["B"] = "b";
MyEnum["C"] = "c";
})(MyEnum || (MyEnum = {}));
Which just gives you this object:
{
A: "a",
B: "b",
C: "c"
}
You can get all the keys (["A", "B", "C"]
) like this:
Object.keys(MyEnum);
And the values (["a", "b", "c"]
):
Object.keys(MyEnum).map(key => MyEnum[key])
Or using Object.values():
Object.values(MyEnum)
%d
is for integers use %f
instead, it works for both float
and double
types:
double d = 1.2;
float f = 1.2f;
System.out.printf("%f %f",d,f); // prints 1.200000 1.200000

javap
to read the bytecodeThe javap
command takes class-names without the .class
extension. Try
javap -c ClassName
javap
will however not give you the implementations of the methods in java-syntax. It will at most give it to you in JVM bytecode format.
To actually decompile (i.e., do the reverse of javac
) you will have to use proper decompiler. See for instance the following related question:
I know some things have changed in AC 2010. However, the old-fashioned ADODB is, as far as I know, the best way to go in VBA. An Example:
Dim cn As ADODB.Connection
Dim cmd As ADODB.Command
Dim prm As ADODB.Parameter
Dim rs As ADODB.Recordset
Dim colReturn As New Collection
Dim SQL As String
SQL = _
"SELECT c.ClientID, c.LastName, c.FirstName, c.MI, c.DOB, c.SSN, " & _
"c.RaceID, c.EthnicityID, c.GenderID, c.Deleted, c.RecordDate " & _
"FROM tblClient AS c " & _
"WHERE c.ClientID = @ClientID"
Set cn = New ADODB.Connection
Set cmd = New ADODB.Command
With cn
.Provider = DataConnection.MyADOProvider
.ConnectionString = DataConnection.MyADOConnectionString
.Open
End With
With cmd
.CommandText = SQL
.ActiveConnection = cn
Set prm = .CreateParameter("@ClientID", adInteger, adParamInput, , mlngClientID)
.Parameters.Append prm
End With
Set rs = cmd.Execute
With rs
If Not .EOF Then
Do Until .EOF
mstrLastName = Nz(!LastName, "")
mstrFirstName = Nz(!FirstName, "")
mstrMI = Nz(!MI, "")
mdDOB = !DOB
mstrSSN = Nz(!SSN, "")
mlngRaceID = Nz(!RaceID, -1)
mlngEthnicityID = Nz(!EthnicityID, -1)
mlngGenderID = Nz(!GenderID, -1)
mbooDeleted = Deleted
mdRecordDate = Nz(!RecordDate, "")
.MoveNext
Loop
End If
.Close
End With
cn.Close
Set rs = Nothing
Set cn = Nothing
The -m
option is probably what you're looking for:
grep -m 10 PATTERN [FILE]
From man grep
:
-m NUM, --max-count=NUM
Stop reading a file after NUM matching lines. If the input is
standard input from a regular file, and NUM matching lines are
output, grep ensures that the standard input is positioned to
just after the last matching line before exiting, regardless of
the presence of trailing context lines. This enables a calling
process to resume a search.
Note: grep stops reading the file once the specified number of matches have been found!
From .Net 3.5 you can use LINQ extension method that (sometimes) makes code flow a bit better.
Usage looks like this:
using System.Linq;
// ...
public void My()
{
var myArray = new[] { "abc", "123", "zyx" };
List<string> myList = myArray.ToList();
}
PS. There's also ToArray()
method that works in other way.

Shortest way (lodash v4):

Usage depends on whether the component's parent has a layout manager or not.
setSize()
-- use when a parent layout manager does not exist;setPreferredSize()
(also its related setMinimumSize
and setMaximumSize
) -- use when a parent layout manager exists.The setSize()
method probably won't do anything if the component's parent is using a layout manager; the places this will typically have an effect would be on top-level components (JFrame
s and JWindow
s) and things that are inside of scrolled panes. You also must call setSize()
if you've got components inside a parent without a layout manager.
Generally, setPreferredSize()
will lay out the components as expected if a layout manager is present; most layout managers work by getting the preferred (as well as minimum and maximum) sizes of their components, then using setSize()
and setLocation()
to position those components according to the layout's rules.
For example, a BorderLayout
tries to make the bounds of its "north" region equal to the preferred size of its north component---they may end up larger or smaller than that, depending on the size of the JFrame
, the size of the other components in the layout, and so on.
I'm using angular2-moment, but usage must be similar.
import { MomentModule } from "angular2-moment";
import moment = require("moment");
export class AppModule {
constructor() {
moment.locale('ru');

You can try
#include <iostream>
#include <conio.h>
int main() {

You basically have 3 options to prevent the PowerShell Console window from closing, that I describe in more detail on my blog post.
PowerShell -NoExit "C:\SomeFolder\SomeScript.ps1"
Read-Host -Prompt "Press Enter to exit"
Global Fix: Change your registry key to always leave the PowerShell Console window open after the script finishes running. Here's the 2 registry keys that would need to be changed:
? Open With ? Windows PowerShell
When you right-click a .ps1 file and choose Open With
Registry Key: HKEY_CLASSES_ROOT\Applications\powershell.exe\shell\open\command
Default Value:
"C:\Windows\System32\WindowsPowerShell\v1.0\powershell.exe" "%1"
Desired Value:
"C:\Windows\System32\WindowsPowerShell\v1.0\powershell.exe" "& \"%1\""
? Run with PowerShell
When you right-click a .ps1 file and choose Run with PowerShell (shows up depending on which Windows OS and Updates you have installed).
Registry Key: HKEY_CLASSES_ROOT\Microsoft.PowerShellScript.1\Shell\0\Command
Default Value:
"C:\Windows\System32\WindowsPowerShell\v1.0\powershell.exe" "-Command" "if((Get-ExecutionPolicy ) -ne 'AllSigned') { Set-ExecutionPolicy -Scope Process Bypass }; & '%1'"
Desired Value:
"C:\Windows\System32\WindowsPowerShell\v1.0\powershell.exe" -NoExit "-Command" "if((Get-ExecutionPolicy ) -ne 'AllSigned') { Set-ExecutionPolicy -Scope Process Bypass }; & \"%1\""
You can download a .reg file from my blog to modify the registry keys for you if you don't want to do it manually.
It sounds like you likely want to use option #2. You could even wrap your whole script in a try block, and only prompt for input if an error occurred, like so:
try
{
# Do your script's stuff
}
catch
{
Write-Error $_.Exception.ToString()
Read-Host -Prompt "The above error occurred. Press Enter to exit."
}
Try the code below:
>>> a = 0.99334
>>> a = int((a * 100) + 0.5) / 100.0 # Adding 0.5 rounds it up
>>> print a
0.99
Here is a basic implementation of a graph. Note: I use vertex which is chained to next vertex. And each vertex has a list pointing to adjacent nodes.
#include <iostream>
using namespace std;
// 1 ->2
// 1->4
// 2 ->3
// 4->3
// 4 -> 5
// Adjacency list
// 1->2->3-null
// 2->3->null
//4->5->null;
// Structure of a vertex
struct vertex {
int i;
struct node *list;
struct vertex *next;
};
typedef struct vertex * VPTR;
// Struct of adjacency list
struct node {
struct vertex * n;
struct node *next;
};
typedef struct node * NODEPTR;
class Graph {
public:
// list of nodes chained together
VPTR V;
Graph() {
V = NULL;
}
void addEdge(int, int);
VPTR addVertex(int);
VPTR existVertex(int i);
void listVertex();
};
// If vertex exist, it returns its pointer else returns NULL
VPTR Graph::existVertex(int i) {
VPTR temp = V;
while(temp != NULL) {
if(temp->i == i) {
return temp;
}
temp = temp->next;
}
return NULL;
}
// Add a new vertex to the end of the vertex list
VPTR Graph::addVertex(int i) {
VPTR temp = new(struct vertex);
temp->list = NULL;
temp->i = i;
temp->next = NULL;
VPTR *curr = &V;
while(*curr) {
curr = &(*curr)->next;
}
*curr = temp;
return temp;
}
// Add a node from vertex i to j.
// first check if i and j exists. If not first add the vertex
// and then add entry of j into adjacency list of i
void Graph::addEdge(int i, int j) {
VPTR v_i = existVertex(i);
VPTR v_j = existVertex(j);
if(v_i == NULL) {
v_i = addVertex(i);
}
if(v_j == NULL) {
v_j = addVertex(j);
}
NODEPTR *temp = &(v_i->list);
while(*temp) {
temp = &(*temp)->next;
}
*temp = new(struct node);
(*temp)->n = v_j;
(*temp)->next = NULL;
}
// List all the vertex.
void Graph::listVertex() {
VPTR temp = V;
while(temp) {
cout <<temp->i <<" ";
temp = temp->next;
}
cout <<"\n";
}
// Client program
int main() {
Graph G;
G.addEdge(1, 2);
G.listVertex();
}
With the above code, you can expand to do DFS/BFS etc.
The Selenium
client bindings will try to locate the geckodriver
executable from the system PATH
. You will need to add the directory containing the executable to the system path.
On Unix systems you can do the following to append it to your system’s search path, if you’re using a bash-compatible shell:
export PATH=$PATH:/path/to/geckodriver
On Windows you need to update the Path system variable to add the full directory path to the executable. The principle is the same as on Unix.
All below configuration for launching latest firefox using any programming language binding is applicable for Selenium2
to enable Marionette explicitly. With Selenium 3.0 and later, you shouldn't need to do anything to use Marionette, as it's enabled by default.
To use Marionette in your tests you will need to update your desired capabilities to use it.
Java :
As exception is clearly saying you need to download latest geckodriver.exe
from here and set downloaded geckodriver.exe
path where it's exists in your computer as system property with with variable webdriver.gecko.driver
before initiating marionette driver and launching firefox as below :-
//if you didn't update the Path system variable to add the full directory path to the executable as above mentioned then doing this directly through code
System.setProperty("webdriver.gecko.driver", "path/to/geckodriver.exe");
//Now you can Initialize marionette driver to launch firefox
DesiredCapabilities capabilities = DesiredCapabilities.firefox();
capabilities.setCapability("marionette", true);
WebDriver driver = new MarionetteDriver(capabilities);
And for Selenium3
use as :-
WebDriver driver = new FirefoxDriver();
If you're still in trouble follow this link as well which would help you to solving your problem
.NET :
var driver = new FirefoxDriver(new FirefoxOptions());
Python :
from selenium import webdriver
from selenium.webdriver.common.desired_capabilities import DesiredCapabilities
caps = DesiredCapabilities.FIREFOX
# Tell the Python bindings to use Marionette.
# This will not be necessary in the future,
# when Selenium will auto-detect what remote end
# it is talking to.
caps["marionette"] = True
# Path to Firefox DevEdition or Nightly.
# Firefox 47 (stable) is currently not supported,
# and may give you a suboptimal experience.
#
# On Mac OS you must point to the binary executable
# inside the application package, such as
# /Applications/FirefoxNightly.app/Contents/MacOS/firefox-bin
caps["binary"] = "/usr/bin/firefox"
driver = webdriver.Firefox(capabilities=caps)
Ruby :
# Selenium 3 uses Marionette by default when firefox is specified
# Set Marionette in Selenium 2 by directly passing marionette: true
# You might need to specify an alternate path for the desired version of Firefox
Selenium::WebDriver::Firefox::Binary.path = "/path/to/firefox"
driver = Selenium::WebDriver.for :firefox, marionette: true
JavaScript (Node.js) :
const webdriver = require('selenium-webdriver');
const Capabilities = require('selenium-webdriver/lib/capabilities').Capabilities;
var capabilities = Capabilities.firefox();
// Tell the Node.js bindings to use Marionette.
// This will not be necessary in the future,
// when Selenium will auto-detect what remote end
// it is talking to.
capabilities.set('marionette', true);
var driver = new webdriver.Builder().withCapabilities(capabilities).build();
Using RemoteWebDriver
If you want to use RemoteWebDriver
in any language, this will allow you to use Marionette
in Selenium
Grid.
Python:
caps = DesiredCapabilities.FIREFOX
# Tell the Python bindings to use Marionette.
# This will not be necessary in the future,
# when Selenium will auto-detect what remote end
# it is talking to.
caps["marionette"] = True
driver = webdriver.Firefox(capabilities=caps)
Ruby :
# Selenium 3 uses Marionette by default when firefox is specified
# Set Marionette in Selenium 2 by using the Capabilities class
# You might need to specify an alternate path for the desired version of Firefox
caps = Selenium::WebDriver::Remote::Capabilities.firefox marionette: true, firefox_binary: "/path/to/firefox"
driver = Selenium::WebDriver.for :remote, desired_capabilities: caps
Java :
DesiredCapabilities capabilities = DesiredCapabilities.firefox();
// Tell the Java bindings to use Marionette.
// This will not be necessary in the future,
// when Selenium will auto-detect what remote end
// it is talking to.
capabilities.setCapability("marionette", true);
WebDriver driver = new RemoteWebDriver(capabilities);
.NET
DesiredCapabilities capabilities = DesiredCapabilities.Firefox();
// Tell the .NET bindings to use Marionette.
// This will not be necessary in the future,
// when Selenium will auto-detect what remote end
// it is talking to.
capabilities.SetCapability("marionette", true);
var driver = new RemoteWebDriver(capabilities);
Note : Just like the other drivers available to Selenium from other browser vendors, Mozilla has released now an executable that will run alongside the browser. Follow this for more details.
You can download latest geckodriver executable to support latest firefox from here
There is a small problem missed in top-voted answers. Namely, character array may contain 0. If we will use constructor with single parameter as pointed above we will lose some data. The possible solution is:
cout << string("123\0 123") << endl;
cout << string("123\0 123", 8) << endl;
Output is:
123
123 123

@marc_s's answer is very great and I've been using it for few years. However, I noticed that the script misses data in some columnstore indexes and doesn't show complete picture. E.g. when you do SUM(TotalSpace)
against the script and compare it with total space database property in Management Studio the numbers don't match in my case (Management Studio shows larger numbers). I modified the script to overcome this issue and extended it a little bit:
select
tables.[name] as table_name,
schemas.[name] as schema_name,
isnull(db_name(dm_db_index_usage_stats.database_id), 'Unknown') as database_name,
sum(allocation_units.total_pages) * 8 as total_space_kb,
cast(round(((sum(allocation_units.total_pages) * 8) / 1024.00), 2) as numeric(36, 2)) as total_space_mb,
sum(allocation_units.used_pages) * 8 as used_space_kb,
cast(round(((sum(allocation_units.used_pages) * 8) / 1024.00), 2) as numeric(36, 2)) as used_space_mb,
(sum(allocation_units.total_pages) - sum(allocation_units.used_pages)) * 8 as unused_space_kb,
cast(round(((sum(allocation_units.total_pages) - sum(allocation_units.used_pages)) * 8) / 1024.00, 2) as numeric(36, 2)) as unused_space_mb,
count(distinct indexes.index_id) as indexes_count,
max(dm_db_partition_stats.row_count) as row_count,
iif(max(isnull(user_seeks, 0)) = 0 and max(isnull(user_scans, 0)) = 0 and max(isnull(user_lookups, 0)) = 0, 1, 0) as no_reads,
iif(max(isnull(user_updates, 0)) = 0, 1, 0) as no_writes,
max(isnull(user_seeks, 0)) as user_seeks,
max(isnull(user_scans, 0)) as user_scans,
max(isnull(user_lookups, 0)) as user_lookups,
max(isnull(user_updates, 0)) as user_updates,
max(last_user_seek) as last_user_seek,
max(last_user_scan) as last_user_scan,

Hope it will be helpful for someone. This script was tested against large TB-wide databases with hundreds of different tables, indexes and schemas.
Try this
if (ModelState.IsValid)
{
//go on as normal
}
else
{
var errors = ModelState.Select(x => x.Value.Errors)
.Where(y=>y.Count>0)
.ToList();
}
errors will be a list of all the errors.
If you want to display the errors to the user, all you have to do is return the model to the view and if you haven't removed the Razor @Html.ValidationFor()
expressions, it will show up.
if (ModelState.IsValid)
{
//go on as normal
}
else
{
return View(model);
}
The view will show any validation errors next to each field and/or in the ValidationSummary if it's present.

In C#, per MSDN library, we have the "const" keyword that does the work of the "#define" keyword in other languages.
"...when the compiler encounters a constant identifier in C# source code (for example, months), it substitutes the literal value directly into the intermediate language (IL) code that it produces." ( https://msdn.microsoft.com/en-us/library/ms173119.aspx )
Initialize constants at time of declaration since there is no changing them.
public const int cMonths = 12;
You will also get this if git doesn't have permissions to read the config files. It will just go up in the hierarchy tree until it needs to cross file systems.
For vector graphics, ImageMagick has both a render resolution and an output size that are independent of each other.
Try something like
convert -density 300 image.eps -resize 1024x1024 image.jpg
Which will render your eps at 300dpi. If 300 * width > 1024, then it will be sharp. If you render it too high though, you waste a lot of memory drawing a really high-res graphic only to down sample it again. I don't currently know of a good way to render it at the "right" resolution in one IM command.
The order of the arguments matters! The -density X
argument needs to go before image.eps
because you want to affect the resolution that the input file is rendered at.
This is not super obvious in the manpage for convert
, but is hinted at:

Here is my function for import database from device storage into android application
private void importDB(){
String dir=Environment.getExternalStorageDirectory().getAbsolutePath();
File sd = new File(dir);
File data = Environment.getDataDirectory();
FileChannel source = null;
FileChannel destination = null;
String backupDBPath = "/data/com.synnlabz.sycryptr/databases/Sycrypter.db";
String currentDBPath = "Sycrypter.db";
File currentDB = new File(sd, currentDBPath);
File backupDB = new File(data, backupDBPath);
try {
source = new FileInputStream(currentDB).getChannel();
destination = new FileOutputStream(backupDB).getChannel();
destination.transferFrom(source, 0, source.size());
source.close();
destination.close();
Toast.makeText(this, "Your Database is Imported !!", Toast.LENGTH_SHORT).show();
} catch (IOException e) {
e.printStackTrace();
}
}
Also for eg. you can use IPC::Run:
use IPC::Run qw(run);
my $pid = 5892;
run [qw(top -H -n 1 -p), $pid],
'|', sub { print grep { /myprocess/ } <STDIN> },
'|', [qw(wc -l)],
'>', \my $out;
print $out;
As of 2017, it seems there's no reliable way to detect an app is installed, and the redirection trick won't work everywhere.
For those like me who needs to deep link directly from emails (quite common), it is worth noting the following:
Sending emails with appScheme:// won't work fine because the links will be filtered in Gmail
Redirecting automatically to appScheme:// is blocked by Chrome: I suspect Chrome requires the redirection to be synchronous to an user interaction (like a click)
You can now deep link without appScheme:// and it's better but it requires a modern platform and additional setup. Android iOS
It is worth noting that other people already thought about this in depth. If you look at how Slack implements his "magic link" feature, you can notice that:
That is most likely jQuery code (more precisely, JavaScript using the jQuery library).
The $
represents the jQuery Function, and is actually a shorthand alias for jQuery
. (Unlike in most languages, the $
symbol is not reserved, and may be used as a variable name.) It is typically used as a selector (i.e. a function that returns a set of elements found in the DOM).
this worked for me....
I added the following line to properties in pom.xml
<properties>
<maven-jar-plugin.version>3.1.1</maven-jar-plugin.version>
</properties>
This is current accepted way to link to a specific lat lon (rather than search for the nearest object).
http://maps.google.com/maps?z=12&t=m&q=loc:38.9419+-78.3020
z
is the zoom level (1-20)t
is the map type ("m" map, "k" satellite, "h" hybrid, "p" terrain, "e" GoogleEarth)q
is the search query, if it is prefixed by loc:
then google assumes it is a lat lon separated by a +
If you want to prevent all caching (e.g. force a reload when using the back button) you need:
no-cache for IE
no-store for Firefox
There's my information about this here:

You can refer to following link for which features are supported in particular version of compiler. It has an exhaustive list of feature support in compiler. Looks GCC follows standard closely and implements before any other compiler.
Regarding your question you can compile using
g++ -std=c++11
for C++11 g++ -std=c++14
for C++14g++ -std=c++17
for C++17g++ -std=c++2a
for C++20, although all features of C++20 are not yet supported refer this link for feature support list in GCC.The list changes pretty fast, keep an eye on the list, if you are waiting for particular feature to be supported.

Here is a easy method.
First parse the JSON from url -
public String readJSONFeed(String URL) {
StringBuilder stringBuilder = new StringBuilder();
HttpClient httpClient = new DefaultHttpClient();
HttpGet httpGet = new HttpGet(URL);
try {
HttpResponse response = httpClient.execute(httpGet);
StatusLine statusLine = response.getStatusLine();
int statusCode = statusLine.getStatusCode();
if (statusCode == 200) {
HttpEntity entity = response.getEntity();
InputStream inputStream = entity.getContent();
BufferedReader reader = new BufferedReader(
new InputStreamReader(inputStream));
String line;
while ((line = reader.readLine()) != null) {
stringBuilder.append(line);
}
inputStream.close();
} else {
Log.d("JSON", "Failed to download file");
}
} catch (Exception e) {
Log.d("readJSONFeed", e.getLocalizedMessage());
}
return stringBuilder.toString();
}
Then place a task and then read the desired value from JSON -
private class ReadPlacesFeedTask extends AsyncTask<String, Void, String> {
protected String doInBackground(String... urls) {
return readJSONFeed(urls[0]);
}
protected void onPostExecute(String result) {
JSONObject json;
try {
json = new JSONObject(result);
////CREATE A JSON OBJECT////
JSONObject data = json.getJSONObject("JSON OBJECT NAME");
////GET A STRING////
String title = data.getString("");
//Similarly you can get other types of data
//Replace String to the desired data type like int or boolean etc.
} catch (JSONException e1) {
e1.printStackTrace();
}
//GETTINGS DATA FROM JSON ARRAY//
try {
JSONObject jsonObject = new JSONObject(result);
JSONArray postalCodesItems = new JSONArray(
jsonObject.getString("postalCodes"));
JSONObject postalCodesItem = postalCodesItems
.getJSONObject(1);
} catch (Exception e) {
Log.d("ReadPlacesFeedTask", e.getLocalizedMessage());
}
}
}
You can then place a task like this -
new ReadPlacesFeedTask()
.execute("JSON URL");
For the question
How can i run a jar file in command prompt but with arguments
.
To pass arguments to the jar file at the time of execution
java -jar myjar.jar arg1 arg2
In the main() method of "Main-Class" [mentioned in the manifest.mft file]of your JAR file. you can retrieve them like this:
String arg1 = args[0];
String arg2 = args[1];
As mentioned by Tom, background-color: rgba(229,229,229, 0.85)
can do the trick.
Place that on the style of the parent element and child wont be affected.
Send XML requests with the raw
data type, then set the Content-Type to text/xml
.
After creating a request, use the dropdown to change the request type to POST.
Open the Body tab and check the data type for raw.
Open the Content-Type selection box that appears to the right and select either XML (application/xml) or XML (text/xml)
Enter your raw XML data into the input field below
Click Send to submit your XML Request to the specified server.
Check the javadocs for java.text.SimpleDateFormat
It describes everything you need.
A trait
is essentially PHP's implementation of a mixin
, and is effectively a set of extension methods which can be added to any class through the addition of the trait
. The methods then become part of that class' implementation, but without using inheritance.
From the PHP Manual (emphasis mine):
Traits are a mechanism for code reuse in single inheritance languages such as PHP. ... It is an addition to traditional inheritance and enables horizontal composition of behavior; that is, the application of class members without requiring inheritance.
An example:
trait myTrait {
function foo() { return "Foo!"; }
function bar() { return "Bar!"; }
}
With the above trait defined, I can now do the following:
class MyClass extends SomeBaseClass {
use myTrait; // Inclusion of the trait myTrait
}
At this point, when I create an instance of class MyClass
, it has two methods, called foo()
and bar()
- which come from myTrait
. And - notice that the trait
-defined methods already have a method body - which an Interface
-defined method can't.
Additionally - PHP, like many other languages, uses a single inheritance model - meaning that a class can derive from multiple interfaces, but not multiple classes. However, a PHP class can have multiple trait
inclusions - which allows the programmer to include reusable pieces - as they might if including multiple base classes.
A few things to note:
-----------------------------------------------
| Interface | Base Class | Trait |
===============================================
> 1 per class | Yes | No | Yes |
---------------------------------------------------------------------
Define Method Body | No | Yes | Yes |
---------------------------------------------------------------------
Polymorphism | Yes | Yes | No |
---------------------------------------------------------------------
Polymorphism:
In the earlier example, where MyClass
extends SomeBaseClass
, MyClass
is an instance of SomeBaseClass
. In other words, an array such as SomeBaseClass[] bases
can contain instances of MyClass
. Similarly, if MyClass
extended IBaseInterface
, an array of IBaseInterface[] bases
could contain instances of MyClass
. There is no such polymorphic construct available with a trait
- because a trait
is essentially just code which is copied for the programmer's convenience into each class which uses it.
Precedence:
As described in the Manual:
An inherited member from a base class is overridden by a member inserted by a Trait. The precedence order is that members from the current class override Trait methods, which in return override inherited methods.
So - consider the following scenario:
class BaseClass {
function SomeMethod() { /* Do stuff here */ }
}
interface IBase {
function SomeMethod();
}
trait myTrait {
function SomeMethod() { /* Do different stuff here */ }
}
class MyClass extends BaseClass implements IBase {
use myTrait;
function SomeMethod() { /* Do a third thing */ }
}
When creating an instance of MyClass, above, the following occurs:
Interface
IBase
requires a parameterless function called SomeMethod()
to be provided.BaseClass
provides an implementation of this method - satisfying the need.trait
myTrait
provides a parameterless function called SomeMethod()
as well, which takes precedence over the BaseClass
-versionclass
MyClass
provides its own version of SomeMethod()
- which takes precedence over the trait
-version.Conclusion
Interface
can not provide a default implementation of a method body, while a trait
can.Interface
is a polymorphic, inherited construct - while a trait
is not.Interface
s can be used in the same class, and so can multiple trait
s.var str = "This-is-a-news-item-";
while (str.contains("-")) {
str = str.replace("-", ' ');
}
alert(str);
I found that one use of str.replace() would only replace the first hyphen, so I looped thru while the input string still contained any hyphens, and replaced them all.
I know this is old, but none of these answers solved the root problem of numpy not saving the array row-wise. I found that this one liner did the trick for me:
b = np.matrix(a)
np.savetxt("file", b)
If all else fails, recompile.
I was recently able to get rid of an unresolved external error in Visual Studio 2012 just by recompiling the offending file. When I re-built, the error went away.
This usually happens when two (or more) libraries have a cyclic dependency. Library A attempts to use symbols in B.lib and library B attempts to use symbols from A.lib. Neither exist to start off with. When you attempt to compile A, the link step will fail because it can't find B.lib. A.lib will be generated, but no dll. You then compile B, which will succeed and generate B.lib. Re-compiling A will now work because B.lib is now found.
You could use g++ --version
in combination with the GCC ABI docs to find out.
HTTP HEAD requests must be treated slightly differently because response.getEntity() is null. Instead, you must capture the HttpContext passed into HttpClient.execute() and retrieve the connection parameter to close it (in HttpComponents 4.1.X anyway).
HttpRequest httpRqst = new HttpHead( uri );
HttpContext httpContext = httpFactory.createContext();
HttpResponse httpResp = httpClient.execute( httpRqst, httpContext );
...
// Close when finished
HttpEntity entity = httpResp.getEntity();
if( null != entity )
// Handles standard 'GET' case
EntityUtils.consume( entity );
else {
ConnectionReleaseTrigger conn =
(ConnectionReleaseTrigger) httpContext.getAttribute( ExecutionContext.HTTP_CONNECTION );
// Handles 'HEAD' where entity is not returned
if( null != conn )
conn.releaseConnection();
}
HttpComponents 4.2.X added a releaseConnection() to HttpRequestBase to make this easier.
I solved this problem with a custom Angular filter as well, but mine takes advantage of regex capturing groups and so the code is really short. I pair it with a separate stripNonNumeric
filter to sanitize the input:
app.filter('stripNonNumeric', function() {
return function(input) {
return (input == null) ? null : input.toString().replace(/\D/g, '');
}
});
The phoneFormat
filter properly formats a phone number with or without the area code. (I did not need international number support.)
app.filter('phoneFormat', function() {
//this establishes 3 capture groups: the first has 3 digits, the second has 3 digits, the third has 4 digits. Strings which are not 7 or 10 digits numeric will fail.
var phoneFormat = /^(\d{3})?(\d{3})(\d{4})$/;
return function(input) {
var parsed = phoneFormat.exec(input);
//if input isn't either 7 or 10 characters numeric, just return input
return (!parsed) ? input : ((parsed[1]) ? '(' + parsed[1] + ') ' : '') + parsed[2] + '-' + parsed[3];
}
});
Use them simply:
<p>{{customer.phone | stripNonNumeric | phoneFormat}}</p>
The regex for the stripNonNumeric
filter came from here.
[Django HTML template doesn't support index as of now], but you can achieve the goal:
If you use Dictionary inside Dictionary in views.py then iteration is possible using key as index. example:
{% for key, value in DictionartResult.items %} <!-- dictionartResult is a dictionary having key value pair-->
<tr align="center">
<td bgcolor="Blue"><a href={{value.ProjectName}}><b>{{value.ProjectName}}</b></a></td>
<td> {{ value.atIndex0 }} </td> <!-- atIndex0 is a key which will have its value , you can treat this key as index to resolve-->
<td> {{ value.atIndex4 }} </td>
<td> {{ value.atIndex2 }} </td>
</tr>
{% endfor %}
Elseif you use List inside dictionary then not only first and last iteration can be controlled, but all index can be controlled. example:
{% for key, value in DictionaryResult.items %}
<tr align="center">
{% for project_data in value %}
{% if forloop.counter <= 13 %} <!-- Here you can control the iteration-->
{% if forloop.first %}
<td bgcolor="Blue"><a href={{project_data}}><b> {{ project_data }} </b></a></td> <!-- it will always refer to project_data[0]-->
{% else %}
<td> {{ project_data }} </td> <!-- it will refer to all items in project_data[] except at index [0]-->
{% endif %}
{% endif %}
{% endfor %}
</tr>
{% endfor %}
End If ;)
// Hope have covered the solution with Dictionary, List, HTML template, For Loop, Inner loop, If Else. Django HTML Documentaion for more methods: https://docs.djangoproject.com/en/2.2/ref/templates/builtins/
Lapack is a Linear Algebra package which is used by R (actually it's used everywhere) underneath solve()
, dgesv spits this kind of error when the matrix you passed as a parameter is singular.
As an addendum: dgesv performs LU decomposition, which, when using your matrix, forces a division by 0, since this is ill-defined, it throws this error. This only happens when matrix is singular or when it's singular on your machine (due to approximation you can have a really small number be considered 0)
I'd suggest you check its determinant if the matrix you're using contains mostly integers and is not big. If it's big, then take a look at this link.
Disclaimer: I am the author of Jsonix, a powerful open-source XML<->JSON JavaScript mapping library.
Today I've released the new version of the Jsonix Schema Compiler, with the new JSON Schema generation feature.
Let's take the Purchase Order schema for example. Here's a fragment:
<xsd:element name="purchaseOrder" type="PurchaseOrderType"/>
<xsd:complexType name="PurchaseOrderType">
<xsd:sequence>
<xsd:element name="shipTo" type="USAddress"/>
<xsd:element name="billTo" type="USAddress"/>
<xsd:element ref="comment" minOccurs="0"/>
<xsd:element name="items" type="Items"/>
</xsd:sequence>
<xsd:attribute name="orderDate" type="xsd:date"/>
</xsd:complexType>
You can compile this schema using the provided command-line tool:
java -jar jsonix-schema-compiler-full.jar
-generateJsonSchema
-p PO
schemas/purchaseorder.xsd
The compiler generates Jsonix mappings as well the matching JSON Schema.
Here's what the result looks like (edited for brevity):
{
"id":"PurchaseOrder.jsonschema#",
"definitions":{
"PurchaseOrderType":{
"type":"object",
"title":"PurchaseOrderType",
"properties":{
"shipTo":{
"title":"shipTo",
"allOf":[
{
"$ref":"#/definitions/USAddress"
}
]
},
"billTo":{
"title":"billTo",
"allOf":[
{
"$ref":"#/definitions/USAddress"
}
]
}, ...
}
},
"USAddress":{ ... }, ...
},
"anyOf":[
{
"type":"object",
"properties":{
"name":{
"$ref":"http://www.jsonix.org/jsonschemas/w3c/2001/XMLSchema.jsonschema#/definitions/QName"
},
"value":{
"$ref":"#/definitions/PurchaseOrderType"
}
},
"elementName":{
"localPart":"purchaseOrder",
"namespaceURI":""
}
}
]
}
Now this JSON Schema is derived from the original XML Schema. It is not exactly 1:1 transformation, but very very close.
The generated JSON Schema matches the generatd Jsonix mappings. So if you use Jsonix for XML<->JSON conversion, you should be able to validate JSON with the generated JSON Schema. It also contains all the required metadata from the originating XML Schema (like element, attribute and type names).
Disclaimer: At the moment this is a new and experimental feature. There are certain known limitations and missing functionality. But I'm expecting this to manifest and mature very fast.
Links:
npm install
function checkArray(array){_x000D_
return array.join("") == array[0].repeat(array.length); _x000D_

None of the above answers helped me, but I just found the solution.
For those who couldn't benefit from any of the above answers;
The issue was that I tried to build project with another Team.
I have 2 different teams as you see
I noticed that I did debug before with second team and xCode automatically created an App ID in second team's developer account.
I opened https://developer.apple.com/ for second account and removed auto-created APP ID
Then worked fine
If the formula already exists in a cell you can fill it down as follows:
On Mac, use CMD instead of CTRL.
An alternative if the formula is in the first cell of a column:
I use Ctrl-b + q which makes it flash number for each pane, redrawing them on the way.
Type :h recording to learn more.
*q* *recording* q{0-9a-zA-Z"} Record typed characters into register {0-9a-zA-Z"} (uppercase to append). The 'q' command is disabled while executing a register, and it doesn't work inside a mapping. {Vi: no recording} q Stops recording. (Implementation note: The 'q' that stops recording is not stored in the register, unless it was the result of a mapping) {Vi: no recording} *@* @{0-9a-z".=*} Execute the contents of register {0-9a-z".=*} [count] times. Note that register '%' (name of the current file) and '#' (name of the alternate file) cannot be used. For "@=" you are prompted to enter an expression. The result of the expression is then executed. See also |@:|. {Vi: only named registers}

Default values are only used if the arguments are not specified. In your case you did specify the arguments - both were supplied, with a value of NULL. (Yes, in this case NULL is considered a real value :-). Try:
EXEC TEST()
Share and enjoy.
Addendum: The default values for procedure parameters are certainly buried in a system table somewhere (see the SYS.ALL_ARGUMENTS
view), but getting the default value out of the view involves extracting text from a LONG field, and is probably going to prove to be more painful than it's worth. The easy way is to add some code to the procedure:
CREATE OR REPLACE PROCEDURE TEST(X IN VARCHAR2 DEFAULT 'P',
Y IN NUMBER DEFAULT 1)
AS
varX VARCHAR2(32767) := NVL(X, 'P');
varY NUMBER := NVL(Y, 1);
BEGIN
DBMS_OUTPUT.PUT_LINE('X=' || varX || ' -- ' || 'Y=' || varY);
END TEST;
you can verify it in android ddms logcat where process id will be same but thread id will be different.
You don't need to change the delimiter to display the right part of the string with cut
.
The -f
switch of the cut
command is the n-TH element separated by your delimiter : :
, so you can just type :
grep puddle2_1557936 | cut -d ":" -f2
Another solutions (adapt it a bit) if you want fun :
Using grep :
grep -oP 'puddle2_1557936:\K.*' <<< 'puddle2_1557936:/home/rogers.williams/folderz/puddle2'
/home/rogers.williams/folderz/puddle2
or still with look around regex
grep -oP '(?<=puddle2_1557936:).*' <<< 'puddle2_1557936:/home/rogers.williams/folderz/puddle2'
/home/rogers.williams/folderz/puddle2
or with perl :
perl -lne '/puddle2_1557936:(.*)/ and print $1' <<< 'puddle2_1557936:/home/rogers.williams/folderz/puddle2'
/home/rogers.williams/folderz/puddle2
or using ruby (thanks to glenn jackman)
ruby -F: -ane '/puddle2_1557936/ and puts $F[1]' <<< 'puddle2_1557936:/home/rogers.williams/folderz/puddle2'
/home/rogers.williams/folderz/puddle2
or with awk :
awk -F'puddle2_1557936:' '{print $2}' <<< 'puddle2_1557936:/home/rogers.williams/folderz/puddle2'
/home/rogers.williams/folderz/puddle2
or with python :
python -c 'import sys; print(sys.argv[1].split("puddle2_1557936:")[1])' 'puddle2_1557936:/home/rogers.williams/folderz/puddle2'
/home/rogers.williams/folderz/puddle2
or using only bash :
IFS=: read _ a <<< "puddle2_1557936:/home/rogers.williams/folderz/puddle2"
echo "$a"
/home/rogers.williams/folderz/puddle2
js<<EOF
var x = 'puddle2_1557936:/home/rogers.williams/folderz/puddle2'
print(x.substr(x.indexOf(":")+1))

If the extra entries in the log bother you but an extra second of start-up time doesn't, just add this to your logging.properties
and forget about it:
org.apache.jasper.servlet.TldScanner.level = WARNING
Another way to turn off CSRF that won't render a null session is to add:
skip_before_action :verify_authenticity_token
in your Rails Controller. This will ensure you still have access to session info.
Again, make sure you only do this in API controllers or in other places where CSRF protection doesn't quite apply.
I follow Kelsey's first set of steps to add the installer classes to my service project, but instead of creating an MSI or setup.exe installer I make the service self installing/uninstalling. Here's a bit of sample code from one of my services you can use as a starting point.
public static int Main(string[] args)
{
if (System.Environment.UserInteractive)
{
// we only care about the first two characters
string arg = args[0].ToLowerInvariant().Substring(0, 2);
switch (arg)
{
case "/i": // install
return InstallService();
case "/u": // uninstall
return UninstallService();
default: // unknown option
Console.WriteLine("Argument not recognized: {0}", args[0]);
Console.WriteLine(string.Empty);
DisplayUsage();
return 1;
}
}
else
{
// run as a standard service as we weren't started by a user
ServiceBase.Run(new CSMessageQueueService());
}
return 0;
}
private static int InstallService()
{
var service = new MyService();
try
{
// perform specific install steps for our queue service.
service.InstallService();
// install the service with the Windows Service Control Manager (SCM)
ManagedInstallerClass.InstallHelper(new string[] { Assembly.GetExecutingAssembly().Location });
}
catch (Exception ex)
{
if (ex.InnerException != null && ex.InnerException.GetType() == typeof(Win32Exception))
{
Win32Exception wex = (Win32Exception)ex.InnerException;
Console.WriteLine("Error(0x{0:X}): Service already installed!", wex.ErrorCode);
return wex.ErrorCode;
}
else
{
Console.WriteLine(ex.ToString());
return -1;
}
}
return 0;
}
private static int UninstallService()
{
var service = new MyQueueService();
try
{
// perform specific uninstall steps for our queue service
service.UninstallService();
// uninstall the service from the Windows Service Control Manager (SCM)

}

{
if (ex.InnerException.GetType() == typeof(Win32Exception))
{
Win32Exception wex = (Win32Exception)ex.InnerException;
Console.WriteLine("Error(0x{0:X}): Service not installed!", wex.ErrorCode);
return wex.ErrorCode;
}
else
{
Console.WriteLine(ex.ToString());
return -1;
}
}
return 0;
}
You are prematurely optimizing. Also, you should really put some thought into whether GET should be used for stuff you're POST-ing, for security reasons.
Path testPath = Paths.get("C:\");
Stream<Path> stream =
Files.find(testPath, 1,
(path, basicFileAttributes) -> {
File file = path.toFile();
return file.getName().endsWith(".java");
});
// Print all files found
stream.forEach(System.out::println);
Open the CSV file with a decent text editor like Notepad++ and add the following text in the first line:
sep=,
Now open it with excel again.
This will set the separator as a comma, or you can change it to whatever you need.

SortExpression="DealCRMID"/>
<asp:BoundField DataField="DealCustomerName" HeaderText="Customer"

SortExpression="SLCode"/>
Code:
private string ConvertSortDirectionToSql(String sortExpression,SortDirection sortDireciton)
{
switch (sortExpression)
{
case "DealCRMID":
ViewState["DealCRMID"]=ChangeSortDirection(ViewState["DealCRMID"].ToString());

A more memory efficient way to iterate over a slice of a list would be to use islice()
from the itertools
module:
from itertools import islice
listOfStuff = (['a','b'], ['c','d'], ['e','f'], ['g','h'])
for item in islice(listOfStuff, 1, 3):
print item
# ['c', 'd']
# ['e', 'f']
However, this can be relatively inefficient in terms of performance if the start value of the range is a large value sinceislice
would have to iterate over the first start value-1 items before returning items.
If your error event handler takes the three arguments (xmlhttprequest, textstatus, and message) when a timeout happens, the status arg will be 'timeout'.
Per the jQuery documentation:
Possible values for the second argument (besides null) are "timeout", "error", "notmodified" and "parsererror".
You can handle your error accordingly then.
I created this fiddle that demonstrates this.
$.ajax({
url: "/ajax_json_echo/",
type: "GET",
dataType: "json",
timeout: 1000,
success: function(response) { alert(response); },
error: function(xmlhttprequest, textstatus, message) {
if(textstatus==="timeout") {
alert("got timeout");
} else {
alert(textstatus);
}
}
});?
With jsFiddle, you can test ajax calls -- it will wait 2 seconds before responding. I put the timeout setting at 1 second, so it should error out and pass back a textstatus of 'timeout' to the error handler.
Hope this helps!
Yes, its possible to have array of objects in PHP.
class MyObject {
private $property;
public function __construct($property) {
$this->Property = $property;
}
}
$ListOfObjects[] = new myObject(1);
$ListOfObjects[] = new myObject(2);
$ListOfObjects[] = new myObject(3);
$ListOfObjects[] = new myObject(4);
print "<pre>";
print_r($ListOfObjects);
print "</pre>";
The answer that was mentioned in this post already several times I have adopted a little bit because I needed to search in only one table too:
(and also made input for the table name a bit more simpler)
ALTER PROC dbo.db_compare_SearchAllTables_sp
(
@SearchStr nvarchar(100),
@TableName nvarchar(256) = ''
)
AS
BEGIN
if PARSENAME(@TableName, 2) is null
set @TableName = 'dbo.' + QUOTENAME(@TableName, '"')
declare @results TABLE(ColumnName nvarchar(370), ColumnValue nvarchar(3630))
SET NOCOUNT ON
DECLARE @ColumnName nvarchar(128) = '', @SearchStr2 nvarchar(110)
SET @SearchStr2 = QUOTENAME('%' + @SearchStr + '%','''')
IF @TableName <> ''
WHILE (@TableName IS NOT NULL) AND (@ColumnName IS NOT NULL)
BEGIN
SET @ColumnName =
(
SELECT MIN(QUOTENAME(COLUMN_NAME))
FROM INFORMATION_SCHEMA.COLUMNS
WHERE TABLE_SCHEMA = PARSENAME(@TableName, 2)
AND TABLE_NAME = PARSENAME(@TableName, 1)
AND DATA_TYPE IN ('char', 'varchar', 'nchar', 'nvarchar')
AND QUOTENAME(COLUMN_NAME) > @ColumnName
)
IF @ColumnName IS NOT NULL
BEGIN
INSERT INTO @results
EXEC
(
'SELECT ''' + @TableName + '.' + @ColumnName + ''', LEFT(' + @ColumnName + ', 3630)
FROM ' + @TableName + ' WITH (NOLOCK) ' +
' WHERE ' + @ColumnName + ' LIKE ' + @SearchStr2
)
END
END
ELSE
WHILE @TableName IS NOT NULL
BEGIN
SET @ColumnName = ''
SET @TableName =
(
SELECT MIN(QUOTENAME(TABLE_SCHEMA) + '.' + QUOTENAME(TABLE_NAME))
FROM INFORMATION_SCHEMA.TABLES
WHERE TABLE_TYPE = 'BASE TABLE'
AND QUOTENAME(TABLE_SCHEMA) + '.' + QUOTENAME(TABLE_NAME) > @TableName
AND OBJECTPROPERTY(
OBJECT_ID(
QUOTENAME(TABLE_SCHEMA) + '.' + QUOTENAME(TABLE_NAME)
), 'IsMSShipped'
) = 0
)
WHILE (@TableName IS NOT NULL) AND (@ColumnName IS NOT NULL)
BEGIN
SET @ColumnName =
(
SELECT MIN(QUOTENAME(COLUMN_NAME))
FROM INFORMATION_SCHEMA.COLUMNS
WHERE TABLE_SCHEMA = PARSENAME(@TableName, 2)
AND TABLE_NAME = PARSENAME(@TableName, 1)
AND DATA_TYPE IN ('char', 'varchar', 'nchar', 'nvarchar')
AND QUOTENAME(COLUMN_NAME) > @ColumnName
)
IF @ColumnName IS NOT NULL
BEGIN
INSERT INTO @results
EXEC
(
'SELECT ''' + @TableName + '.' + @ColumnName + ''', LEFT(' + @ColumnName + ', 3630)
FROM ' + @TableName + ' WITH (NOLOCK) ' +
' WHERE ' + @ColumnName + ' LIKE ' + @SearchStr2
)
END
END
END
SELECT ColumnName, ColumnValue FROM @results
END
You can check like this:
int x;
cin >> x;
if (cin.fail()) {
//Not an int.
}
Furthermore, you can continue to get input until you get an int via:
#include <iostream>
int main() {
int x;
std::cin >> x;
while(std::cin.fail()) {
std::cout << "Error" << std::endl;
std::cin.clear();
std::cin.ignore(256,'\n');
std::cin >> x;
}
std::cout << x << std::endl;
return 0;
}
EDIT: To address the comment below regarding input like 10abc, one could modify the loop to accept a string as an input. Then check the string for any character not a number and handle that situation accordingly. One needs not clear/ignore the input stream in that situation. Verifying the string is just numbers, convert the string back to an integer. I mean, this was just off the cuff. There might be a better way. This won't work if you're accepting floats/doubles (would have to add '.' in the search string).
#include <iostream>
#include <string>
int main() {
std::string theInput;
int inputAsInt;
std::getline(std::cin, theInput);
while(std::cin.fail() || std::cin.eof() || theInput.find_first_not_of("0123456789") != std::string::npos) {
std::cout << "Error" << std::endl;
if( theInput.find_first_not_of("0123456789") == std::string::npos) {
std::cin.clear();
std::cin.ignore(256,'\n');
}
std::getline(std::cin, theInput);
}
std::string::size_type st;
inputAsInt = std::stoi(theInput,&st);
std::cout << inputAsInt << std::endl;
return 0;
}
You can use the following:
<style type="text/css">
table { page-break-inside:auto }
tr { page-break-inside:avoid; page-break-after:auto }
</style>
Refer the W3C's CSS Print Profile specification for details.
And also refer the Salesforce developer forums.
Use ffmpeglib to connect to the stream.
These functions may be useful. But take a look in the docs
av_open_input_stream(...);
av_find_stream_info(...);
avcodec_find_decoder(...);
avcodec_open(...);
avcodec_alloc_frame(...);
You would need a little algo to get a complete frame, which is available here
http://www.dranger.com/ffmpeg/tutorial01.html
Once you get a frame you could copy the video data (for each plane if needed) into a IplImage which is an OpenCV image object.
You can create an IplImage using something like...
IplImage *p_gray_image = cvCreateImage(size, IPL_DEPTH_8U, 1);
Once you have an IplImage, you could perform all sorts of image operations available in the OpenCV lib
A one-liner for object configs:
new Date(new Date().setHours(0,0,0,0));
When creating an element:
dateFieldConfig = {
name: "mydate",
value: new Date(new Date().setHours(0, 0, 0, 0)),
}

In order to ensure there is no compilation error, place the file on your classpath when compiling (-cp command-line option, or check your IDE documentation).
You can port-forward with another ssh
command that need not be tied to how you are connecting to the server (as an alternative to the other answer). Thus, the ordering of the below steps is arbitrary.
from your local machine, run
ssh -N -f -L localhost:16006:localhost:6006 <user@remote>
on the remote machine, run:
tensorboard --logdir <path> --port 6006
Then, navigate to (in this example) http://localhost:16006 on your local machine.
(explanation of ssh command:
-N
: no remote commands
-f
: put ssh in the background
-L <machine1>:<portA>:<machine2>:<portB>
:
forward <machine1>:<portA>
(local scope) to <machine2>:<portB>
(remote scope)
According to Google documentation they said that this is the best way to do it. First create this function to find out how many markers there are/
function setMapOnAll(map1) {
for (var i = 0; i < markers.length; i++) {
markers[i].setMap(map1);
}
}
Next create another function to take away all these markers
function clearMarker(){
setMapOnAll(null);
}
Then create this final function to erase all the markers when ever this function is called upon.
function delateMarkers(){
clearMarker()
markers = []
//console.log(markers) This is just if you want to
}
Hope that helped good luck
When the propagation setting is PROPAGATION_REQUIRED, a logical transaction scope is created for each method upon which the setting is applied. Each such logical transaction scope can determine rollback-only status individually, with an outer transaction scope being logically independent from the inner transaction scope. Of course, in case of standard PROPAGATION_REQUIRED behavior, all these scopes will be mapped to the same physical transaction. So a rollback-only marker set in the inner transaction scope does affect the outer transaction's chance to actually commit (as you would expect it to).
http://static.springsource.org/spring/docs/3.1.x/spring-framework-reference/html/transaction.html
You have two options for displaying the Map
For showing local POIs around a Lat, Long use Places APIs
Let's call keys
the list/iterator of keys that you are given to remove. I'd do this:
keys_to_remove = set(keys).intersection(set(mydict.keys()))
for key in keys_to_remove:
del mydict[key]
You calculate up front all the affected items and operate on them.
I prefer to create a new dictionary over mutating an existing one, so I would probably also consider this:
keys_to_keep = set(mydict.keys()) - set(keys)
new_dict = {k: v for k, v in mydict.iteritems() if k in keys_to_keep}
or:
keys_to_keep = set(mydict.keys()) - set(keys)
new_dict = {k: mydict[k] for k in keys_to_keep}
You could register to the KeyDown-Event of the Textbox, look if the pressed key is Enter and then execute the EventHandler of the button:
private void buttonTest_Click(object sender, EventArgs e)
{
MessageBox.Show("Hello World");
}
private void textBoxTest_KeyDown(object sender, KeyEventArgs e)
{
if (e.KeyCode == Keys.Enter)
{
buttonTest_Click(this, new EventArgs());
}
}
Here's another way:
>>> L = range (11)
>>> map(lambda x: x if x%2 else None, L)
[None, 1, None, 3, None, 5, None, 7, None, 9, None]
Modern CPUs provide a lot of low-level instructions, besides the usual arithmetic and logic, known as extensions, e.g. SSE2, SSE4, AVX, etc. From the Wikipedia:
Advanced Vector Extensions (AVX) are extensions to the x86 instruction set architecture for microprocessors from Intel and AMD proposed by Intel in March 2008 and first supported by Intel with the Sandy Bridge processor shipping in Q1 2011 and later on by AMD with the Bulldozer processor shipping in Q3 2011. AVX provides new features, new instructions and a new coding scheme.
In particular, AVX introduces fused multiply-accumulate (FMA) operations, which speed up linear algebra computation, namely dot-product, matrix multiply, convolution, etc. Almost every machine-learning training involves a great deal of these operations, hence will be faster on a CPU that supports AVX and FMA (up to 300%). The warning states that your CPU does support AVX (hooray!).
I'd like to stress here: it's all about CPU only.
Because tensorflow default distribution is built without CPU extensions, such as SSE4.1, SSE4.2, AVX, AVX2, FMA, etc. The default builds (ones from pip install tensorflow
) are intended to be compatible with as many CPUs as possible. Another argument is that even with these extensions CPU is a lot slower than a GPU, and it's expected for medium- and large-scale machine-learning training to be performed on a GPU.
If you have a GPU, you shouldn't care about AVX support, because most expensive ops will be dispatched on a GPU device (unless explicitly set not to). In this case, you can simply ignore this warning by
# Just disables the warning, doesn't take advantage of AVX/FMA to run faster
import os
os.environ['TF_CPP_MIN_LOG_LEVEL'] = '2'
... or by setting export TF_CPP_MIN_LOG_LEVEL=2
if you're on Unix. Tensorflow is working fine anyway, but you won't see these annoying warnings.
If you don't have a GPU and want to utilize CPU as much as possible, you should build tensorflow from the source optimized for your CPU with AVX, AVX2, and FMA enabled if your CPU supports them. It's been discussed in this question and also this GitHub issue. Tensorflow uses an ad-hoc build system called bazel and building it is not that trivial, but is certainly doable. After this, not only will the warning disappear, tensorflow performance should also improve.
Swift 4+:
textField.clearButtonMode = UITextField.ViewMode.whileEditing
or even shorter:
textField.clearButtonMode = .whileEditing
This will do the job:
<div style="position:absolute; right:0;">Hello world</div>

If you are running python 3 then you need to change the print statements to print functions, i.e. put things in brackets () after print statements.
The only thing that you will see the above do is the prints unless you have something listening on 127.0.0.1 port 5005
as you are sending a packet not receiving it - so you need to implement and start the other part of the example in another console window first so it is waiting for the message.

I think your tensorflow is not installed for local environment.The best way of installing tensorflow is to create virtualenv as describe in the tensorflow installation guide Tensorflow Installation .After installing you can activate the invironment and can run anypython script under that environment.
use Javascript sort() function
var $tbody = $('table tbody');
$tbody.find('tr').sort(function(a,b){
var tda = $(a).find('td:eq(1)').text(); // can replace 1 with the column you want to sort on
var tdb = $(b).find('td:eq(1)').text(); // this will sort on the second column
// if a < b return 1
return tda < tdb ? 1
// else if a > b return -1
: tda > tdb ? -1
// else they are equal - return 0
: 0;
}).appendTo($tbody);
If you want ascending you just have to reverse the > and <
Change the logic accordingly for you.

Copying file to host:
scp SourceFile remoteuser@remotehost:/directory/TargetFile
Copying file from host:
scp user@host:/directory/SourceFile TargetFile
Copying directory recursively from host:
scp -r user@host:/directory/SourceFolder TargetFolder
NOTE: If the host is using a port other than port 22, you can specify it with the -P option:
scp -P 2222 user@host:/directory/SourceFile TargetFile
No, an architect has a different job than a programmer. The architect is more concerned with nonfunctional ("ility") requirements. Like reliability, maintainability, security, and so on. (If you don't agree, consider this thought experiment: compare a CGI program written in C that does a complicated website, versus a Ruby on Rails implementation. They both have the same functional behavior; choosing an RoR architecture has what advantages.)
Generally, a "solution architect" is about the whole system -- hardware, software, and all -- which an "application architect" is working within a fixed platform, but the terms aren't that rigorous or well standardized.
I am just wondering why to use some libraries for JWT token decoding and verification at all.
Encoded JWT token can be created using following pseudocode
var headers = base64URLencode(myHeaders);
var claims = base64URLencode(myClaims);
var payload = header + "." + claims;
var signature = base64URLencode(HMACSHA256(payload, secret));
var encodedJWT = payload + "." + signature;
It is very easy to do without any specific library. Using following code:
using System;
using System.Text;
using System.Security.Cryptography;
public class Program
{
// More info: https://stormpath.com/blog/jwt-the-right-way/
public static void Main()
{
var header = "{\"typ\":\"JWT\",\"alg\":\"HS256\"}";
var claims = "{\"sub\":\"1047986\",\"email\":\"[email protected]\",\"given_name\":\"John\",\"family_name\":\"Doe\",\"primarysid\":\"b521a2af99bfdc65e04010ac1d046ff5\",\"iss\":\"http://example.com\",\"aud\":\"myapp\",\"exp\":1460555281,\"nbf\":1457963281}";
var b64header = Convert.ToBase64String(Encoding.UTF8.GetBytes(header))
.Replace('+', '-')
.Replace('/', '_')
.Replace("=", "");
var b64claims = Convert.ToBase64String(Encoding.UTF8.GetBytes(claims))
.Replace('+', '-')
.Replace('/', '_')
.Replace("=", "");
var payload = b64header + "." + b64claims;
Console.WriteLine("JWT without sig: " + payload);
byte[] key = Convert.FromBase64String("mPorwQB8kMDNQeeYO35KOrMMFn6rFVmbIohBphJPnp4=");
byte[] message = Encoding.UTF8.GetBytes(payload);
string sig = Convert.ToBase64String(HashHMAC(key, message))
.Replace('+', '-')
.Replace('/', '_')
.Replace("=", "");
Console.WriteLine("JWT with signature: " + payload + "." + sig);
}
private static byte[] HashHMAC(byte[] key, byte[] message)
{
var hash = new HMACSHA256(key);
return hash.ComputeHash(message);
}
}
The token decoding is reversed version of the code above.To verify the signature you will need to the same and compare signature part with calculated signature.
UPDATE: For those how are struggling how to do base64 urlsafe encoding/decoding please see another SO question, and also wiki and RFCs
The fastest way is to do a*a
or a**2
or np.square(a)
whereas np.power(a, 2)
showed to be considerably slower.
np.power()
allows you to use different exponents for each element if instead of 2
you pass another array of exponents. From the comments of @GarethRees I just learned that this function will give you different results than a**2
or a*a
, which become important in cases where you have small tolerances.
I've timed some examples using NumPy 1.9.0 MKL 64 bit, and the results are shown below:
In [29]: a = np.random.random((1000, 1000))
In [30]: timeit a*a
100 loops, best of 3: 2.78 ms per loop
In [31]: timeit a**2
100 loops, best of 3: 2.77 ms per loop
In [32]: timeit np.power(a, 2)
10 loops, best of 3: 71.3 ms per loop
Textarea resize control is available via the CSS3 resize property:
textarea { resize: both; } /* none|horizontal|vertical|both */
textarea.resize-vertical{ resize: vertical; }
textarea.resize-none { resize: none; }
Allowable values self-explanatory: none
(disables textarea resizing), both
, vertical
and horizontal
.
Notice that in Chrome, Firefox and Safari the default is both
.
If you want to constrain the width and height of the textarea element, that's not a problem: these browsers also respect max-height
, max-width
, min-height
, and min-width
CSS properties to provide resizing within certain proportions.
Code example:
#textarea-wrapper {_x000D_
padding: 10px;_x000D_
background-color: #f4f4f4;_x000D_
width: 300px;_x000D_
}_x000D_
_x000D_
#textarea-wrapper textarea {_x000D_
min-height:50px;_x000D_
max-height:120px;_x000D_
width: 290px;_x000D_
}_x000D_
_x000D_
#textarea-wrapper textarea.vertical { _x000D_
resize: vertical;_x000D_
}
_x000D_
<div id="textarea-wrapper">_x000D_
<label for="resize-default">Textarea (default):</label>_x000D_
<textarea name="resize-default" id="resize-default"></textarea>_x000D_
_x000D_
<label for="resize-vertical">Textarea (vertical):</label>_x000D_
<textarea name="resize-vertical" id="resize-vertical" class="vertical">Notice this allows only vertical resize!</textarea>_x000D_
</div>

For some reason the solution mentioned for httpClient above didn't worked for me. At the end I was able to make it work by correctly overriding the method when implementing the custom SSLSocketFactory class.
@Override
public Socket createSocket(Socket socket, String host, int port, boolean autoClose)
throws IOException, UnknownHostException
{
return sslFactory.createSocket(socket, host, port, autoClose);
}
@Override
public Socket createSocket() throws IOException {
return sslFactory.createSocket();
}
This is how it worked perfectly for me. You can see the full custom class and implementing on the following thread: http://blog.syedgakbar.com/2012/07/21/android-https-and-not-trusted-server-certificate-error/
You cannot use percentages to define the dimensions of a View inside a RelativeLayout. The best ways to do it is to use LinearLayout and weights, or a custom Layout.
With Python 2, this doesn't work for non-English words in UTF-8. In this case decode('utf-8')
can help:
>>> s='????????'
>>> print s.lower()
????????
>>> print s.decode('utf-8').lower()
????????
This is a trick,
function OpenInNewTab(url) {
var win = window.open(url, '_blank');
win.focus();
}
In most cases, this should happen directly in the onclick handler for the link to prevent pop-up blockers, and the default "new window" behavior. You could do it this way, or by adding an event listener to your DOM object.
<div onclick="OpenInNewTab();">Something To Click On</div>
I had the same issue after upgrading my system.
In my case, the problem was caused by the order of loading configuration files.
In the /etc/httpd/httpd.conf
initally it was defined as follows:
IncludeOptional conf.d/*.conf
IncludeOptional sites-enabled/*.conf
After some hours of attempts, I tried the following order:
IncludeOptional sites-enabled/*.conf
IncludeOptional conf.d/*.conf
And it works fine now.
For linux users, and to sum up and add to what others have said here, you should know the following:
Global variables are not evil. $CLASSPATH is specifically what Java uses to look through multiple directories to find all the different classes it needs for your script (unless you explicitly tell it otherwise with the -cp override).
The colon (":") character separates the different directories. There is only one $CLASSPATH and it has all the directories in it. So, when you run "export CLASSPATH=...." you want to include the current value "$CLASSPATH" in order to append to it. For example:
export CLASSPATH=.
export CLASSPATH=$CLASSPATH:/usr/share/java/mysql-connector-java-5.1.12.jar
In the first line above, you start CLASSPATH out with just a simple 'dot' which is the path to your current working directory. With that, whenever you run java it will look in the current working directory (the one you're in) for classes. In the second line above, $CLASSPATH grabs the value that you previously entered (.) and appends the path to a mysql dirver. Now, java will look for the driver AND for your classes.
echo $CLASSPATH
is super handy, and what it returns should read like a colon-separated list of all the directories you want java looking in for what it needs to run your script.
Tomcat does not use CLASSPATH. Read what to do about that here: https://tomcat.apache.org/tomcat-8.0-doc/class-loader-howto.html
Here is how I do this.
Dim TAV() As Variant
Dim ArrayToPreserve() as Variant
TAV = ArrayToPreserve
ReDim ArrayToPreserve(nDim1, nDim2)
For i = 0 To UBound(TAV, 1)
For j = 0 To UBound(TAV, 2)
ArrayToPreserve(i, j) = TAV(i, j)
Next j
Next i
The filesystem size can be different from the patition size. To repair you need to do this
df -h
see what is the name of the partition say /dev/sda3
resize2fs /dev/sda3
I was getting this same error, but for me this was due to a method in a base class (in Project A) having the output type changed from a non-void type to void. A child class existed in Project B (which I didn't want used and had marked obsolete) that I missed when performing this update and hence started throwing this error.

tail -f logfile | grep org.springframework | cut -c 900-

Hope this works.
Building on and updating a number of earlier responses (thanks: SilentGhost, nosklo, Ramkumar) a simple portable timer would use timeit
's default_timer()
:
>>> import timeit
>>> tic=timeit.default_timer()
>>> # Do Stuff
>>> toc=timeit.default_timer()
>>> toc - tic #elapsed time in seconds
This will return the elapsed wall clock (real) time, not CPU time. And as described in the timeit
documentation chooses the most precise available real-world timer depending on the platform.
ALso, beginning with Python 3.3 this same functionality is available with the time.perf_counter
performance counter. Under 3.3+ timeit.default_timer() refers to this new counter.
For more precise/complex performance calculations, timeit
includes more sophisticated calls for automatically timing small code snippets including averaging run time over a defined set of repetitions.
Your question answers itself ;) If og_date
contains the date, it's probably a string, so og_date.value
is undefined.
Simply use og_date.split('-')
instead of og_date.value.split('-')
For rows, try this, where Name
is the joint index column (can be a list for multiple common columns, or specify left_on
and right_on
):
m = df1.merge(df2, on='Name', how='outer', suffixes=['', '_'], indicator=True)
The indicator=True
setting is useful as it adds a column called _merge
, with all changes between df1
and df2
, categorized into 3 possible kinds: "left_only", "right_only" or "both".
For columns, try this:
set(df1.columns).symmetric_difference(df2.columns)
SELECT CONCAT (zipcode, ' - ', city, ', ', state) AS COMBINED FROM TABLE
You might want to use jQuery's .addClass and .removeClass commands, and create two different classes for the states. This, to me, would be the best practice way of doing it.
PHP_EOL is a predefined constant in PHP since PHP 4.3.10 and PHP 5.0.2. See the manual posting:
Using this will save you extra coding on cross platform developments.
IE.
$data = 'some data'.PHP_EOL;
$fp = fopen('somefile', 'a');
fwrite($fp, $data);
If you looped through this twice you would see in 'somefile':
some data
some data

The first thing that you have to know, is that the concept of NaN is implemented directly on the CPU hardware.
All major modern CPUs seem to follow IEEE 754 which specifies floating point formats, and NaNs, which are just special float values, are part of that standard.
Therefore, the concept will be the very similar across any language, including Java which just emits floating point code directly to the CPU.
Before proceeding, you might want to first read up the following answers I've written:
Now for some Java action. Most of the functions of interest that are not in the core language live inside java.lang.Float
.

}
}
Run with:
javac Nan.java && java -ea Nan
Output:
nan 0x7fc00000 NaN
zero_div_zero 0x7fc00000 NaN
sqrt_negative 0xffc00000 NaN
log_negative 0xffc00000 NaN
inf_minus_inf 0x7fc00000 NaN
inf_times_zero 0x7fc00000 NaN
quiet_nan1 0x7fc00001 NaN
quiet_nan2 0x7fc00002 NaN
signaling_nan1 0x7fa00001 NaN
signaling_nan2 0x7fa00002 NaN
nan_minus 0xffc00000 NaN
positive_inf 0x7f800000 Infinity
negative_inf 0xff800000 -Infinity
one_div_zero 0x7f800000 Infinity
log_zero 0xff800000 -Infinity
So from this we learn a few things:
weird floating operations that don't have any sensible result give NaN:
0.0f / 0.0f
sqrt(-1.0f)
log(-1.0f)
generate a NaN
.
In C, it is actually possible to request signals to be raised on such operations with feenableexcept
to detect them, but I don't think it is exposed in Java: Why does integer division by zero 1/0 give error but floating point 1/0.0 returns "Inf"?
weird operations that are on the limit of either plus or minus infinity however do give +- infinity instead of NaN
1.0f / 0.0f
log(0.0f)
0.0
almost falls in this category, but likely the problem is that it could either go to plus or minus infinity, so it was left as NaN.
if NaN is the input of a floating operation, the output also tends to be NaN
there are several possible values for NaN 0x7fc00000
, 0x7fc00001
, 0x7fc00002
, although x86_64 seems to generate only 0x7fc00000
.
NaN and infinity have similar binary representation.
Let's break down a few of them:
nan = 0x7fc00000 = 0 11111111 10000000000000000000000
positive_inf = 0x7f800000 = 0 11111111 00000000000000000000000
negative_inf = 0xff800000 = 1 11111111 00000000000000000000000
| | |
| | mantissa
| exponent
|
sign
From this we confirm what IEEE754 specifies:
NaNs can be either positive or negative (top bit), although it this has no effect on normal operations

One more solution...
var strg= 'This is my string';
for(indx in strg){
alert(strg[indx]);
}
Use it by this Method:
str.encode().decode()
Feel free to use this how ever you like.
/*
* The extendStrArray() method will takes a number "n" and
* a String Array "strArray" and will return a new array
* containing 'n' new positions. This new returned array
* can then be assigned to a new array, or the existing
* one to "extend" it, it contain the old value in the
* new array with the addition n empty positions.
*/
private String[] extendStrArray(int n, String[] strArray){
String[] old_str_array = strArray;
String[] new_str_array = new String[(old_str_array.length + n)];
for(int i = 0; i < old_str_array.length; i++ ){
new_str_array[i] = old_str_array[i];
}//end for loop
return new_str_array;
}//end extendStrArray()
Basically I would use it like this:
String[] students = {"Tom", "Jeff", "Ashley", "Mary"};
// 4 new students enter the class so we need to extend the string array
students = extendStrArray(4, students); //this will effectively add 4 new empty positions to the "students" array.
Just enable parsing of the autoexec.bat in the registry, using these instructions.

I had a similar issue for setting proxy server on a container.
The solution I'm using is an entrypoint script, and another script for environment variables configuration. Using RUN, you assure the configuration script runs on build, and ENTRYPOINT when you run the container.
--build-arg is used on command line to set proxy user and password.
As I need the same environment variables on container startup, I used a file to "persist" it from build to run.
The entrypoint script looks like:
#!/bin/bash
# Load the script of environment variables
. /root/configproxy.sh
# Run the main container command
exec "$@"
configproxy.sh
#!/bin/bash
function start_config {
read u p < /root/proxy_credentials
export HTTP_PROXY=http://$u:[email protected]:8080
export HTTPS_PROXY=https://$u:[email protected]:8080
/bin/cat <<EOF > /etc/apt/apt.conf
Acquire::http::proxy "http://$u:[email protected]:8080";
Acquire::https::proxy "https://$u:[email protected]:8080";
EOF
}
if [ -s "/root/proxy_credentials" ]
then
start_config
fi
And in the Dockerfile, configure:
# Base Image
FROM ubuntu:18.04
ARG user
ARG pass
USER root
# -z the length of STRING is zero
# [] are an alias for test command
# if $user is not empty, write credentials file
RUN if [ ! -z "$user" ]; then echo "${user} ${pass}">/root/proxy_credentials ; fi
#copy bash scripts
COPY configproxy.sh /root
COPY startup.sh .
RUN ["/bin/bash", "-c", ". /root/configproxy.sh"]
# Install dependencies and tools
#RUN apt-get update -y && \
# apt-get install -yqq --no-install-recommends \
# vim iputils-ping
ENTRYPOINT ["./startup.sh"]
CMD ["sh", "-c", "bash"]
Build without proxy settings
docker build -t img01 -f Dockerfile .
Build with proxy settings
docker build -t img01 --build-arg user=<USER> --build-arg pass=<PASS> -f Dockerfile .
Take a look here.
Replacing the border-color with outline-color should work.
From this article on web.archive.org :
The trick is to use the OnClientClick and UseSubmitBehavior properties of the button control. There are other methods, involving code on the server side to add attributes, but I think the simplicity of doing it this way is much more attractive:
<asp:Button runat="server" ID="BtnSubmit" OnClientClick="this.disabled = true; this.value = 'Submitting...';" UseSubmitBehavior="false" OnClick="BtnSubmit_Click" Text="Submit Me!" />
OnClientClick allows you to add client side OnClick script. In this case, the JavaScript will disable the button element and change its text value to a progress message. When the postback completes, the newly rendered page will revert the button back its initial state without any additional work.
The one pitfall that comes with disabling a submit button on the client side is that it will cancel the browser’s submit, and thus the postback. Setting the UseSubmitBehavior property to false tells .NET to inject the necessary client script to fire the postback anyway, instead of relying on the browser’s form submission behavior. In this case, the code it injects would be:
__doPostBack('BtnSubmit','')
This is added to the end of our OnClientClick code, giving us this rendered HTML:
<input type="button" name="BtnSubmit" onclick="this.disabled = true; this.value ='Submitting...';__doPostBack('BtnSubmit','')" value="Submit Me!" id="BtnSubmit" />
This gives a nice button disable effect and processing text, while the postback completes.
public int getPopularElement(int[] a)
{
int count = 1, tempCount;
int popular = a[0];
int temp = 0;
for (int i = 0; i < (a.length - 1); i++)
{
temp = a[i];
tempCount = 0;
for (int j = 1; j < a.length; j++)
{
if (temp == a[j])
tempCount++;
}
if (tempCount > count)
{
popular = temp;
count = tempCount;
}
}
return popular;
}
If you want to use all stylesheet in your app just adds this line in application.html.erb. Insert it inside <head>
tag
<%= stylesheet_link_tag controller.controller_name , media: 'all', 'data-turbolinks-track': 'reload' %>
Also, to specify the same class CSS on a different controller
Add this line in the body
of application.html.erb
<body class="<%= controller.controller_name %>-<%= controller.action_name %>">
So, now for example I would like to change the p
tag in 'home' controller and 'index' action.
Inside index.scss
file adds.
.nameOfController-nameOfAction <tag> { }
.home-index p {
color:red !important;
}
The Expires entity-header field gives the date/time after which the response is considered stale.The Cache-control:maxage field gives the age value (in seconds) bigger than which response is consider stale.
Althought above header field give a mechanism to client to decide whether to send request to the server. In some condition, the client send a request to sever and the age value of response is bigger then the maxage value ,dose it means server needs to send the resource to client? Maybe the resource never changed.
In order to resolve this problem, HTTP1.1 gives last-modifided head. The server gives the last modified date of the response to client. When the client need this resource, it will send If-Modified-Since head field to server. If this date is before the modified date of the resouce, the server will sends the resource to client and gives 200 code.Otherwise,it will returns 304 code to client and this means client can use the resource it cached.
If you like to keep it fixed width, for example 10 digits, do it like this
Key = i.ToString("0000000000");
Replace with as many digits as you like.
i = 123
will then result in Key = "0000000123"
.
Netcat is your friend:
nc -z localhost 6000 || echo "no tunnel open"
Here is how to do it if you are using a SimpleCursorAdapter
(where columnName
is the name of the db column that you used to populate your spinner
):
private int getIndex(Spinner spinner, String columnName, String searchString) {
//Log.d(LOG_TAG, "getIndex(" + searchString + ")");
if (searchString == null || spinner.getCount() == 0) {
return -1; // Not found
}
else {
Cursor cursor = (Cursor)spinner.getItemAtPosition(0);
int initialCursorPos = cursor.getPosition(); // Remember for later
int index = -1; // Not found
for (int i = 0; i < spinner.getCount(); i++) {
cursor.moveToPosition(i);
String itemText = cursor.getString(cursor.getColumnIndex(columnName));
if (itemText.equals(searchString)) {
index = i; // Found!
break;
}
}
cursor.moveToPosition(initialCursorPos); // Leave cursor as we found it.
return index;
}
}
Also (a refinement of Akhil's answer) this is the corresponding way to do it if you are filling your Spinner from an array:
private int getIndex(Spinner spinner, String searchString) {
if (searchString == null || spinner.getCount() == 0) {
return -1; // Not found
}
else {
for (int i = 0; i < spinner.getCount(); i++) {
if (spinner.getItemAtPosition(i).toString().equals(searchString)) {
return i; // Found!
}
}
return -1; // Not found
}
};
Simple solution:
<iframe onload="this.style.height=this.contentWindow.document.body.scrollHeight + 'px';" ...></iframe>
This works when the iframe and parent window are in the same domain. It does not work when the two are in different domains.
You can use the step attribute to the input type number:
<input type="number" id="totalAmt" step="0.1"></input>
step="any"
will allow any decimal.
step="1"
will allow no decimal.
step="0.5"
will allow 0.5; 1; 1.5; ...
step="0.1"
will allow 0.1; 0.2; 0.3; 0.4; ...
This should work:
[ int(x) for x in "40 1".split(" ") ]
I am facing a strange behavior.
SELECT INTO and SET Both works for some variables and not for others. Event syntaxes are the same
SET @Invoice_UserId := (SELECT UserId FROM invoice WHERE InvoiceId = @Invoice_Id LIMIT 1); -- Working
SET @myamount := (SELECT amount FROM invoice WHERE InvoiceId = @Invoice_Id LIMIT 1); - Not working
SELECT Amount INTO @myamount FROM invoice WHERE InvoiceId = 29 LIMIT 1; - Not working
If I run these queries directly then works, but not working in stored procedure.
The toString()
implementation of java.util.Date
does not depend on the way the class is imported. It always returns a nice formatted date.
The toString()
you see comes from another class.
Specific import have precedence over wildcard imports.
in this case
import other.Date
import java.util.*
new Date();
refers to other.Date
and not java.util.Date
.
The odd thing is that
import other.*
import java.util.*
Should give you a compiler error stating that the reference to Date is ambiguous because both other.Date
and java.util.Date
matches.
If you are still recieving the InvalidKeyException when running my AES encryption program with 256 bit keys, but not with 128 bit keys, it is because you have not installed the new policy JAR files correctly, and has nothing to do with BouncyCastle (which is also restrained by those policy files). Try uninstalling, then re-installing java and then replaceing the old jar's with the new unlimited strength ones. Other than that, I'm out of ideas, best of luck.
You can see the policy files themselves if you open up the lib/security/local_policy.jar and US_export_policy.jar files in winzip and look at the conatined *.policy files in notepad and make sure they look like this:
default_local.policy:
// Country-specific policy file for countries with no limits on crypto strength.
grant {
// There is no restriction to any algorithms.
permission javax.crypto.CryptoAllPermission;
};
default_US_export.policy:
// Manufacturing policy file.
grant {
// There is no restriction to any algorithms.
permission javax.crypto.CryptoAllPermission;
};

p = subprocess.run("echo 'hello world!'", capture_output=True, shell=True, encoding="utf8")
assert p.stdout == 'hello world!\n'
First up, this has got nothing to do with String
, it is about arrays.. and that too specifically about declarative initialization of arrays.
As discussed by everyone in almost every answer here, you can, while declaring a variable, use:
String names[] = {"x","y","z"};
However, post declaration, if you want to assign an instance of an Array:
names = new String[] {"a","b","c"};
AFAIK, the declaration syntax is just a syntactic sugar and it is not applicable anymore when assigning values to variables because when values are assigned you need to create an instance properly.
However, if you ask us why it is so? Well... good luck getting an answer to that. Unless someone from the Java committee answers that or there is explicit documentation citing the said syntactic sugar.
Should it be necessary to manually remove a service:
You will have to reboot before the list gets updated in services
I had this problem when moving my .edmx
database first model from one project to another.
I simply did the following:
app.config
or web.config
SyntaxError: missing ) after argument list.
the issue also may occur if you pass string directly without a single or double quote.
$('#contentData').append("<div class='media'><div class='media-body'><a class='btn' href='" + type + "' onclick=\"(canLaunch(' + v.LibraryItemName + '))\">View »</a></div></div>").
so always keep the habit to pass in a quote like
onclick=\"(canLaunch(\'' + v.LibraryItemName + '\'))"\
If you want using Internet in your app as well as check the network state i.e. Is app is connected to the internet then you have to use below code outside of the application
tag.
For Internet Permission:
<uses-permission android:name="android.permission.INTERNET" />
For Access network state:
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
Complete Code:
<uses-sdk
android:minSdkVersion="9"
android:targetSdkVersion="16" />
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
<application
android:allowBackup="true"
android:icon="@drawable/ic_launcher"
android:label="@string/app_name"
android:theme="@style/AppTheme" >
<activity
android:name=".MainActivity"
android:label="@string/app_name" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
</application>

Use a library like LumenWorks to do your CSV reading. It'll handle fields with quotes in them and will likely overall be more robust than your custom solution by virtue of having been around for a long time.
Swift 3.0 makes this a bit more verbose:
let string = "Hello.World"
let needle: Character = "."
if let idx = string.characters.index(of: needle) {
let pos = string.characters.distance(from: string.startIndex, to: idx)
print("Found \(needle) at position \(pos)")
}
else {
print("Not found")
}
Extension:
extension String {
public func index(of char: Character) -> Int? {
if let idx = characters.index(of: char) {
return characters.distance(from: startIndex, to: idx)
}
return nil
}
}
In Swift 2.0 this has become easier:
let string = "Hello.World"
let needle: Character = "."
if let idx = string.characters.indexOf(needle) {
let pos = string.startIndex.distanceTo(idx)
print("Found \(needle) at position \(pos)")
}
else {
print("Not found")
}
Extension:
extension String {
public func indexOfCharacter(char: Character) -> Int? {
if let idx = self.characters.indexOf(char) {
return self.startIndex.distanceTo(idx)
}
return nil
}
}
Swift 1.x implementation:
For a pure Swift solution one can use:
let string = "Hello.World"
let needle: Character = "."
if let idx = find(string, needle) {
let pos = distance(string.startIndex, idx)
println("Found \(needle) at position \(pos)")
}
else {
println("Not found")
}
As an extension to String
:
extension String {
public func indexOfCharacter(char: Character) -> Int? {
if let idx = find(self, char) {
return distance(self.startIndex, idx)
}
return nil
}
}
If you are trying to use AngularJs 1.6.6 as of 21/10/2017 the following parameter works as .success and has been depleted. The .then() method takes two arguments: a response and an error callback which will be called with a response object.
$scope.login = function () {
$scope.btntext = "Please wait...!";
$http({
method: "POST",
url: '/Home/userlogin', // link UserLogin with HomeController
data: $scope.user
}).then(function (response) {
console.log("Result value is : " + parseInt(response));
data = response.data;
$scope.btntext = 'Login';
if (data == 1) {
window.location.href = '/Home/dashboard';
}
else {
alert(data);
}
}, function (error) {
alert("Failed Login");
});
The above snipit works for a login page.
In asp.net core this works differerently:
public class SomeOtherClass
{
private readonly IHttpContextAccessor _httpContextAccessor;
private ISession _session => _httpContextAccessor.HttpContext.Session;
public SomeOtherClass(IHttpContextAccessor httpContextAccessor)
{
_httpContextAccessor = httpContextAccessor;
}
public void TestSet()
{
_session.SetString("Test", "Ben Rules!");
}
public void TestGet()
{
var message = _session.GetString("Test");
}
}

You should add { static: false }
as a second option for @ViewChild
. This causes the query results to be resolved after change detection runs, allowing your @ViewChild
to be updated after the value changes.
Example:
export class AppComponent {
@ViewChild('contentPlaceholder', { static: false }) contentPlaceholder: ElementRef;
display = false;
constructor(private changeDetectorRef: ChangeDetectorRef) {
}
show() {
this.display = true;
this.changeDetectorRef.detectChanges(); // not required
console.log(this.contentPlaceholder);
}
}

In general, it is considered best-practice to use relative URLs, so that your website will not be bound to the base URL of where it is currently deployed. For example, it will be able to work on localhost, as well as on your public domain, without modifications.
For Laravel 5.4 and if you are using mix helper, use
<link href="{{ mix('/css/app.css') }}" rel="stylesheet">
<script src="{{ mix('/js/app.js') }}"></script>
Using filter()
and lambda
would provide a neat and terse method of removing unwanted values:
newEmails = list(filter(lambda x : x != '[email protected]', emails))
This does not modify emails. It creates the new list newEmails containing only elements for which the anonymous function returned True.
