This will work with "org.bouncycastle.util.encoders.Hex" following package
return new String(Hex.encode(digest));
Its in bouncycastle jar.
I use this SFTP API which has SCP called Zehon, it's great, so easy to use with a lot of sample code. Here is the site http://www.zehon.com
Unfortunately, the tool mentioned above is blocked by several antivirus vendors. If this is the case for you then take a look at the following.
Open the non-exportable cert in the cert store and locate the Thumbprint value.
Next, open regedit to the path below and locate the registry key matching the thumbprint value.
An export of the registry key will contain the complete certificate including the private key. Once exported, copy the export to the other server and import it into the registry.
The cert will appear in the certificate manager with the private key included.
Machine Store: HKLM\SOFTWARE\Microsoft\SystemCertificates\MY\Certificates User Store: HKCU\SOFTWARE\Microsoft\SystemCertificates\MY\Certificates
In a pinch, you could save the export as a backup of the certificate.
The answer by Steve Jessop explains well, why you can't use std::map::operator[]
on a const std::map
. Gabe Rainbow's answer suggests a nice alternative. I'd just like to provide some example code on how to use map::at()
. So, here is an enhanced example of your function()
:
void function(const MAP &map, const std::string &findMe) {
try {
const std::string& value = map.at(findMe);
std::cout << "Value of key \"" << findMe.c_str() << "\": " << value.c_str() << std::endl;
// TODO: Handle the element found.
}
catch (const std::out_of_range&) {
std::cout << "Key \"" << findMe.c_str() << "\" not found" << std::endl;
// TODO: Deal with the missing element.
}
}
And here is an example main()
function:
int main() {
MAP valueMap;
valueMap["string"] = "abc";
function(valueMap, "string");
function(valueMap, "strong");
return 0;
}
Output:
Value of key "string": abc
Key "strong" not found

Use:
#include <iostream>
...
std::cout << std::hex << a;
There are many other options to control the exact formatting of the output number, such as leading zeros and upper/lower case.
A covering index is one which can satisfy all requested columns in a query without performing a further lookup into the clustered index.
There is no such thing as a covering query.
Have a look at this Simple-Talk article: Using Covering Indexes to Improve Query Performance.
or you can do like
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
new Thread( SampleFunction ).Start();
}
void SampleFunction()
{
// Gets executed on a seperate thread and
// doesn't block the UI while sleeping
for ( int i = 0; i < 5; i++ )
{
this.Invoke( ( MethodInvoker )delegate()
{
textBox1.Text += "hi";
} );
Thread.Sleep( 1000 );
}
}
}
From a question I asked not long ago:
Conditional operator cannot cast implicitly?
Given:
Bool aBoolValue;
Where aBoolValue
is assigned either True or False;
The following will not compile:
Byte aByteValue = aBoolValue ? 1 : 0;
But this would:
Int anIntValue = aBoolValue ? 1 : 0;
The answer provided is pretty good too.
Much simpler actually:
Method 1:
Invoke-Expression $scriptPath $argumentList
Method 2:
& $scriptPath $argumentList
Method 3:
$scriptPath $argumentList
If you have spaces in your scriptPath
, don't forget to escape them `"$scriptPath`"
You were on the right track, but there were some problems with the code you posted. First of all, there was no closing bracket for the while loop. Secondly, $line_of_text would be overwritten with every loop iteration, which is fixed by changing the = to a .= in the loop. Third, you're exploding the literal characters '\n' and not an actual newline; in PHP, single quotes will denote literal characters, but double quotes will actually interpret escaped characters and variables.
<?php
$file = fopen("members.txt", "r");
$i = 0;
while (!feof($file)) {
$line_of_text .= fgets($file);
}
$members = explode("\n", $line_of_text);
fclose($file);
print_r($members);
?>
If you want to reindent the block you're in without having to type any chords, you can do:
[[=]]
Try the following in your view to check the output from each. The first one updates when the view is called a second time. My controller uses the key ShowCreateButton and has the optional parameter _createAction with a default value - you can change this to your key/parameter
@Html.TextBox("_createAction", null, new { Value = (string)ViewBag.ShowCreateButton })
@Html.TextBox("_createAction", ViewBag.ShowCreateButton )
@ViewBag.ShowCreateButton
What I do is something just a little bit different from @Chase answer:
var employees = {};
// ...and then:
employees.accounting = new Array();
for (var i = 0; i < someArray.length; i++) {
var temp_item = someArray[i];
// Maybe, here make something like:
// temp_item.name = 'some value'
employees.accounting.push({
"firstName" : temp_item.firstName,
"lastName" : temp_item.lastName,
"age" : temp_item.age
});
}
And that work form me!
I hope it could be useful for some body else!
Similarities:
DTDs and Schemas both perform the same basic functions:
Differences:
DTDs are better for text-intensive applications, while schemas have several advantages for data-intensive workflows.
Schemas are written in XML and thusly follow the same rules, while DTDs are written in a completely different language.
Examples:
DTD:
<?xml version="1.0" encoding="UTF-8"?>
<!ELEMENT employees (Efirstname, Elastname, Etitle, Ephone, Eemail)>
<!ELEMENT Efirstname (#PCDATA)>
<!ELEMENT Elastname (#PCDATA)>

Almost the same as Audrius cooked up some months ago, but you might find it a bit more readable with the defaults in the function head - the way you are used to with python:
@app.route('/<user_id>')
@app.route('/<user_id>/<username>')
def show(user_id, username='Anonymous'):
return user_id + ':' + username
I know It's been a while since this question was asked but I just run into the same issue of inconsistency with onMouseLeave() What I did is to use onMouseOut() for the drop-list and on mouse leave for the whole menu, it is reliable and works every time I've tested it. I saw the events here in the docs: https://facebook.github.io/react/docs/events.html#mouse-events here is an example using https://www.w3schools.com/bootstrap/bootstrap_dropdowns.asp:
handleHoverOff(event){
//do what ever, for example I use it to collapse the dropdown
let collapsing = true;
this.setState({dropDownCollapsed : collapsing });
}
render{
return(
<div class="dropdown" onMouseLeave={this.handleHoverOff.bind(this)}>
<button class="btn btn-primary dropdown-toggle" type="button" data-toggle="dropdown">Dropdown Example
<span class="caret"></span></button>
<ul class="dropdown-menu" onMouseOut={this.handleHoverOff.bind(this)}>
<li><a href="#">bla bla 1</a></li>
<li><a href="#">bla bla 2</a></li>
<li><a href="#">bla bla 3</a></li>
</ul>
</div>
)
}
You can loop through the cells of any column in a table by knowing just its name and not its position. If the table is in sheet1 of the workbook:
Dim rngCol as Range
Dim cl as Range
Set rngCol = Sheet1.Range("TableName[ColumnName]")
For Each cl in rngCol
cl.Value = "PHEV"
Next cl
The code above will loop through the data values only, excluding the header row and the totals row. It is not necessary to specify the number of rows in the table.
Use this to find the location of any column in a table by its column name:
Dim colNum as Long
colNum = Range("TableName[Column name to search for]").Column
This returns the numeric position of a column in the table.
This is a great place to use regular expressions.
By using a regular expression, you can replace all that code with just one line.
You can use the following regex to validate your requirements:
[0-9]*\.?[0-9]*
In other words: zero or more numeric characters, followed by zero or one period(s), followed by zero or more numeric characters.
You can replace your code with this:
function validate(s) {
var rgx = /^[0-9]*\.?[0-9]*$/;
return s.match(rgx);
}
That code can replace your entire function!
Note that you have to escape the period with a backslash (otherwise it stands for 'any character').
For more reading on using regular expressions with javascript, check this out:
You can also test the above regex here:
Explanation of the regex used above:
The brackets mean "any character inside these brackets." You can use a hyphen (like above) to indicate a range of chars.
The *
means "zero or more of the previous expression."
[0-9]*
means "zero or more numbers"
The backslash is used as an escape character for the period, because period usually stands for "any character."
The ?
means "zero or one of the previous character."
The ^
represents the beginning of a string.
The $
represents the end of a string.
Starting the regex with ^
and ending it with $
ensures that the entire string adheres to the regex pattern.
Hope this helps!
Try using System.getProperty("line.separator")
to get a new line.
What helped me with that error was Juan's answer - https://stackoverflow.com/a/20204635/4433222 But wasn't enough - after struggling I found out that an XML file needs to be saved with UTF-8 without BOM encoding.
The solution wasn't working for "normal" UTF-8.
To be able to connect with your user from any IP address, do the following:
Allow mysql server to accept remote connections. For this open mysqld.conf file:
sudo gedit /etc/mysql/mysql.conf.d/mysqld.cnf
Search for the line starting with "bind-address" and set it's value to 0.0.0.0
bind-address = 0.0.0.0
and finally save the file.
Note: If you’re running MySQL 8+, the bind-address
directive will not be in the mysqld.cnf
file by default. In this case, add the directive to the bottom of the file /etc/mysql/mysql.conf.d/mysqld.cnf
.
Now restart the mysql server, either with systemd
or use the older service
command. This depends on your operating system:
sudo systemctl restart mysql # for ubuntu
sudo systemctl restart mysqld.service # for debian
Finally, mysql server is now able to accept remote connections.
Now we need to create a user and grant it permission, so we can be able to login with this user remotely.
Connect to MySQL database as root, or any other user with root privilege.
mysql -u root -p
now create desired user in both localhost and '%' wildcard and grant permissions on all DB's as such .
CREATE USER 'myuser'@'localhost' IDENTIFIED BY 'mypass';
CREATE USER 'myuser'@'%' IDENTIFIED BY 'mypass';
Then,
GRANT ALL ON *.* TO 'myuser'@'localhost';
GRANT ALL ON *.* TO 'myuser'@'%';
And finally don't forget to flush privileges
FLUSH PRIVILEGES;
Note: If you’ve configured a firewall on your database server, you will also need to open port 3306
MySQL’s default port to allow traffic to MySQL.
Hope this helps ;)
"If your content is really interesting, then there is little you can ultimately do to protect it"
That's true, but most copying, in my experience, has nothing to do with "ultimately" or geeks or determined plagiarists or anything like that. It's usually casual copying by clueless people, and even a simple, easily defeated protection (easily defeated by folks like us, that is) works quite well to stop them. They don't know anything about "view source" or caches or anything else... heck, they don't even know what a web browser is or that they're using one.
it's android:button="@drawable/selector_checkbox"
to make it work
Use @Input
to pass your data to child components and then use ngOnChanges
(https://angular.io/api/core/OnChanges) to see if that @Input

(2012 answer, may be out of date) If you want to support pre Honeycomb, you will need to put in backward compatibility prior to API 13. Something like:
int measuredWidth = 0;
int measuredHeight = 0;
WindowManager w = getWindowManager();
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.HONEYCOMB_MR2) {
Point size = new Point();
w.getDefaultDisplay().getSize(size);
measuredWidth = size.x;
measuredHeight = size.y;
} else {
Display d = w.getDefaultDisplay();
measuredWidth = d.getWidth();
measuredHeight = d.getHeight();
}
Of course the deprecated methods will eventually be taken out of the the most recent SDKs, but while we still rely on most of our users having Android 2.1, 2.2 and 2.3, this is what we are left with.
These are all a matter of convenience.
Basically, if the question were 'Do we need to use body-parser
?' The answer is 'No'. We can come up with the same information from the client-post-request using a more circuitous route that will generally be less flexible and will increase the amount of code we have to write to get the same information.
This is kind of the same as asking 'Do we need to use express
to begin with?' Again, the answer there is no, and again, really it all comes down to saving us the hassle of writing more code to do the basic things that express comes with 'built-in'.
On the surface - body-parser
makes it easier to get at the information contained in client requests in a variety of formats instead of making you capture the raw data streams and figuring out what format the information is in, much less manually parsing that information into useable data.

You can use the ThenBy and ThenByDescending extension methods:
foobarList.OrderBy(x => x.Foo).ThenBy( x => x.Bar)
Another solution that uses jQuery and JSON, so you can access the parameter values through an object.
var loc = window.location.href;
var param = {};
if(loc.indexOf('?') > -1)
{
var params = loc.substr(loc.indexOf('?')+1, loc.length).split("&");
var stringJson = "{";
for(var i=0;i<params.length;i++)
{
var propVal = params[i].split("=");
var paramName = propVal[0];
var value = propVal[1];
stringJson += "\""+paramName+"\": \""+value+"\"";
if(i != params.length-1) stringJson += ",";
}
stringJson += "}";
// parse string with jQuery parseJSON
param = $.parseJSON(stringJson);
}
Assuming your URL is http://example.com/?search=hello+world&language=en&page=3
After that it's only a matter of using the parameters like this:
param.language
to return
en
The most useful usage of this is to run it at page load and make use of a global variable to use the parameters anywhere you might need them.
If your parameter contains numeric values then just parse the value.
parseInt(param.page)
If there are no parameters param
will just be an empty object.
You can create a countdown timer using applet, below is the code,

import java.net.*;
/**
* An applet that counts down from a specified time. When it reaches 00:00,
* it optionally plays a sound and optionally moves the browser to a new page.
* Place the mouse over the applet to pause the count; move it off to resume.
* This class demonstrates most applet methods and features.

This works for me:

html{overflow:scroll!important;}
</style>
Note: if you need scrollbar in any other element, also add css {overflow:scroll!important;}
to that element
Had a directory by the same name as the file i was trying to write, so people can look out for that as well.
Inner join and natural join are almost same but there is a slight difference between them. The difference is in natural join no need to specify condition but in inner join condition is obligatory. If we do specify the condition in inner join , it resultant tables is like a cartesian product.
Try this:
$("#textbox").bind('paste',function() {alert("Change detected!");});
See demo on JSFiddle.

This issue mainly happened for old dependencies.
There have 2 solution:
First one:
Update all old dependencies
and ClassPaths from Project level gradle
files.
classpath 'com.android.tools.build:gradle:3.3.1'
classpath 'com.google.gms:google-services:4.2.0'
Second one:
Your project Migrate to AndroidX
From Android Studio Menu -> Refanctor -> Migrate to AndroidX

The code you have is a white with low opacity.
If something white with a low opacity is above something black, you end up with a lighter shade of gray. Above red? Lighter red, etc. That is how opacity works.
Here is a simple demo.
If you want it to look 'more white', make it less opaque:
background:rgba(255,255,255, 0.9);
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 +
A TortoiseSVN equivalent solution of the accepted answer (I had written this in an internal document for my company as we are newly adopting SVN) follows. I thought it would be helpful to share here as well:
Checking out a single file: Subversion does not support checkout of a single file, it only supports checkout of directory structures. (Reference: http://subversion.tigris.org/faq.html#single-file-checkout). This is because with every directory that is checked out as a working copy, the metadata regarding modifications/file revisions is stored as an internal hidden folder (.svn/_svn). This is not supported currently (v1.6) for single files.
Alternate recommended strategy: You will have to do the checkout directory part only once, following that you can directly go and checkout your single files. Do a sparse checkout of the parent folder and directory structure. A sparse checkout is basically checking out only the folder structure without populating the content files. So you checkout only the directory structures and need not checkout ALL the files as was the concern. Reference: http://tortoisesvn.net/docs/release/TortoiseSVN_en/tsvn-dug-checkout.html
Step 1: Proceed to repository browser
Step 2: Right click the parent folder within the repository containing all the files that you wish to work on and Select Checkout.
Step 3: Within new popup window, ensure that the checkout directory points to the correct location on your local PC. There will also be a dropdown menu labeled “checkout depth”. Choose “Only this item” or “Immediate children, including folders” depending on your requirement. Second option is recommended as, if you want to work on nested folder, you can directly proceed the next time otherwise you will have to follow this whole procedure again for the nested folder.
Step 4: The parent folder(s) should now be available within your locally chosen folder and is now being monitored with SVN (a hidden folder “.svn” or “_svn” should now be present). Within the repository now, right click the single file that you wish to have checked out alone and select the “Update Item to revision” option. The single file can now be worked on and checked back into the repository.
I hope this helps.
Use this:
$root = 'REST_SERVICE_URL'
$user = "user"
$pass= "password"
$secpasswd = ConvertTo-SecureString $pass -AsPlainText -Force
$credential = New-Object System.Management.Automation.PSCredential($user, $secpasswd)
$result = Invoke-RestMethod $root -Credential $credential
When running this command:
ALTER TABLE MYTABLENAME MODIFY CONSTRAINT MYCONSTRAINTNAME_FK ENABLE;
I got this error:
ORA-02270: no matching unique or primary key for this column-list
02270. 00000 - "no matching unique or primary key for this column-list"
*Cause: A REFERENCES clause in a CREATE/ALTER TABLE statement
gives a column-list for which there is no matching unique or primary
key constraint in the referenced table.
*Action: Find the correct column names using the ALL_CONS_COLUMNS
The referenced table has a primary key constraint with matching type. The root cause of this error, in my case, was that the primary key constraint was disabled.

You can use template facility in C++ to do this. I did something like this :
template<typename T, size_t col>
T process(T a[][col], size_t row) {
...
}
the problem with this approach is that for every value of col which you provide, the a new function definition is instantiated using the template. so,
int some_mat[3][3], another_mat[4,5];
process(some_mat, 3);
process(another_mat, 4);
instantiates the template twice to produce 2 function definitions (one where col = 3 and one where col = 5).
You might try Upsert
:
require 'upsert' # add this to your Gemfile
require 'csv'
u = Upsert.new Moulding.connection, Moulding.table_name
CSV.foreach(file, headers: true) do |row|
selector = { name: row['name'] } # this treats "name" as the primary key and prevents the creation of duplicates by name
setter = row.to_hash
u.row selector, setter
end
If this is what you want, you might also consider getting rid of the auto-increment primary key from the table and setting the primary key to name
. Alternatively, if there is some combination of attributes that form a primary key, use that as the selector. No index is necessary, it will just make it faster.
import shutil

shutil.which(command) is not None
As a one-liner of Jan-Philip Gehrcke Answer:
cmd_exists = lambda x: shutil.which(x) is not None
As a def:
def cmd_exists(cmd):
return shutil.which(cmd) is not None
my_command = 'ls'
any(
(
os.access(os.path.join(path, my_command), os.X_OK)
and os.path.isfile(os.path.join(path, my_command)
)
for path in os.environ["PATH"].split(os.pathsep)
)
This is a one-liner of Jay's Answer, Also here as a lambda func:
cmd_exists = lambda x: any((os.access(os.path.join(path, x), os.X_OK) and os.path.isfile(os.path.join(path, x))) for path in os.environ["PATH"].split(os.pathsep))
cmd_exists('ls')
Or lastly, indented as a function:
def cmd_exists(cmd, path=None):
""" test if path contains an executable file with name
"""
if path is None:
path = os.environ["PATH"].split(os.pathsep)
for prefix in path:
filename = os.path.join(prefix, cmd)
executable = os.access(filename, os.X_OK)
is_not_directory = os.path.isfile(filename)
if executable and is_not_directory:

You need to use the matplotlib API directly rather than going through the pylab interface. There's a good example here:
http://www.dalkescientific.com/writings/diary/archive/2005/04/23/matplotlib_without_gui.html
You are almost there, all you need is start anchor (^
) and end anchor ($
):
^[0-9]{1,45}$
\d
is short for the character class [0-9]
. You can use that as:
^\d{1,45}$
The anchors force the pattern to match entire input, not just a part of it.
Your regex [0-9]{1,45}
looks for 1 to 45 digits, so string like foo1
also get matched as it contains 1
.
^[0-9]{1,45}
looks for 1 to 45 digits but these digits must be at the beginning of the input. It matches 123
but also 123foo
[0-9]{1,45}$
looks for 1 to 45 digits but these digits must be at the end of the input. It matches 123
but also foo123
^[0-9]{1,45}$
looks for 1 to 45 digits but these digits must be both at the start and at the end of the input, effectively it should be entire input.
A BLOB is a Binary Large OBject. It is used to store large quantities of binary data in a database.
You can use it to store any kind of binary data that you want, includes images, video, or any other kind of binary data that you wish to store.
Different DBMSes treat BLOBs in different ways; you should read the documentation of the databases you are interested in to see how (and if) they handle BLOBs.
If it is the sum of all the numbers you want, I made a little snippet for you that can handle both + and - using a regex (I left some print-calls in there to help visualise what happens):
final String string = " " + 5 + "\n" + "-" + " " + 9+"\n"+"+"+" "+5; //Or get the value from a TextView
final Pattern pattern = Pattern.compile("(-?).?(\\d+)");
Matcher matcher = pattern.matcher(string);
System.out.print(string);
System.out.print('\n');
int sum = 0;
while( matcher.find() ){
System.out.print(matcher.group(1));
System.out.print(matcher.group(2));
System.out.print('\n');
sum += Integer.parseInt(matcher.group(1)+matcher.group(2));
}
System.out.print("\nSum: "+sum);
This code prints the following:
5
- 9
+ 5
5
-9
5
Sum: 1
Edit: sorry if I misunderstood your question, it was a little bit unclear what you wanted to do. I assumed you wanted to get the sum of the numbers as an integer rather than a string.
Edit2: to get the numbers separate from each other, do something like this instead:
final String string = " " + 5 + "\n" + "-" + " " + 9+"\n"+"+"+" "+5; //Or get the value from a TextView
final Pattern pattern = Pattern.compile("(-?).?(\\d+)");
Matcher matcher = pattern.matcher(string);
ArrayList<Integer> numbers = new ArrayList<Integer>();
while( matcher.find() ){
numbers.add(Integer.parseInt(matcher.group(1)+matcher.group(2)));
}

You could always use Replace()
since you're performing this on the workbook's Name, which will almost certainly end with .xlsm
by virtue of using VBA.
Using ActiveWorkbook per your example:
Replace(Application.ActiveWorkbook.Name, ".xlsm", "")
Using ThisWorkbook:
Replace(Application.ThisWorkbook.Name, ".xlsm", "")

I had this error message with boot2docker on windows with the docker-oracle-xe-11g image (https://registry.hub.docker.com/u/wnameless/oracle-xe-11g/).
The reason was that the virtual box disk was full (check with boot2docker.exe ssh df
). Deleting old images and restarting the container solved the problem.
The same way -- e.g. if you have an 8-bit char, 7 bits can be used for magnitude and 1 for sign. So an unsigned char might range from 0 to 255, whilst a signed char might range from -128 to 127 (for example).
If you are asking about cache where eclipse stores your project and workspace information right click on your project(s) and choose refresh. Then go to project in the menu on top of the window and click "clean".
This typically does what you need.
If it does not try to remove project from the workspace (just press "delete" on the project and then say that you DO NOT want to remove the sources). Then open project again.
If this does not work too, do the same with the workspace. If this still does not work, perform fresh checkout of your project from source control and create new workspace.
Well, this should work.
In your controller, render the new
action from your create action if validation fails, with an instance variable, @car
populated from the user input (i.e., the params
hash). Then, in your view, add a logic check (either an if block around the form
or a ternary on the helpers, your choice) that automatically sets the value of the form fields to the params
values passed in to @car if car exists. That way, the form will be blank on first visit and in theory only be populated on re-render in the case of error. In any case, they will not be populated unless @car
is set.
You need to create a service to be able to share data between controllers.
app.factory('myService', function() {
var savedData = {}
function set(data) {
savedData = data;
}
function get() {
return savedData;
}
return {
set: set,
get: get
}
});
In your controller A:
myService.set(yourSharedData);
In your controller B:
$scope.desiredLocation = myService.get();
Remember to inject myService in the controllers by passing it as a parameter.
In ascending order you can use:
sorted_data= sorted(non_sorted_data, key=lambda k: (k[1],k[0]))
or in descending order you can use:
sorted_data= sorted(non_sorted_data, key=lambda k: (k[1],k[0]),reverse=True)

None of the above solutions worked for me. The following however works like a charm:-

because it is auto generate on the DB, and continue with persist command.
I had to write code for a similar problem. One way that I was able to solve it used a recursive method of coding.
static String removeChar(String word, char charToRemove)
{
for(int i = 0; i < word.lenght(); i++)
{
if(word.charAt(i) == charToRemove)
{
String newWord = word.substring(0, i) + word.substring(i + 1);
return removeChar(newWord, charToRemove);
}
}
return word;
}
Most of the code I've seen on this topic doesn't use recursion so hopefully I can help you or someone who has the same problem.

"testCases" :
{
"case.1" :
{
"scenario" : "this the case 1.",
"result" : "this is a very long line which is not easily readble. \
so i would like to write it in multiple lines. \
but, i do NOT require any new lines in the output."
}
}
}
I just have the same situation as you and I have just fixed this problem.
It is the reason that you have configured even number of zookeepers which directly result in this problem,try to change your number of zookeeper node to a odd one.
for example the original status of my zookeeper cluster is consisted of 4 nodes,then just remove one of them which result in the number of node to be 3 well ,now its ok to startup zookeeper cluster
below is the output of successfully connect to zookeeper server

Detecting sheet of paper is kinda old school. If you want to tackle skew detection then it is better if you straightaway aim for text line detection. With this you will get the extremas left, right, top and bottom. Discard any graphics in the image if you dont want and then do some statistics on the text line segments to find the most occurring angle range or rather angle. This is how you will narrow down to a good skew angle. Now after this you put these parameters the skew angle and the extremas to deskew and chop the image to what is required.
As for the current image requirement, it is better if you try CV_RETR_EXTERNAL instead of CV_RETR_LIST.
Another method of detecting edges is to train a random forests classifier on the paper edges and then use the classifier to get the edge Map. This is by far a robust method but requires training and time.
Random forests will work with low contrast difference scenarios for example white paper on roughly white background.
I like simple javascript, and I usually have jQuery around. Here's what I came up with, based off mparkuk's:
function typeInTextarea(el, newText) {
var start = el.prop("selectionStart")
var end = el.prop("selectionEnd")
var text = el.val()
var before = text.substring(0, start)
var after = text.substring(end, text.length)
el.val(before + newText + after)
el[0].selectionStart = el[0].selectionEnd = start + newText.length
el.focus()
}
$("button").on("click", function() {
typeInTextarea($("textarea"), "some text")
return false
})
Here's a demo: http://codepen.io/erikpukinskis/pen/EjaaMY?editors=101
It's not January 1, 1753 but select cast('' as datetime) wich reveals: 1900-01-01 00:00:00.000 gives the default value by SQL server. (Looks more uninitialized to me anyway)
select 1 from table
will return a column of 1's for every row in the table. You could use it with a where statement to check whether you have an entry for a given key, as in:
if exists(select 1 from table where some_column = 'some_value')
What your friend was probably saying is instead of making bulk selects with select * from table, you should specify the columns that you need precisely, for two reasons:
1) performance & you might retrieve more data than you actually need.
2) the query's user may rely on the order of columns. If your table gets updated, the client will receive columns in a different order than expected.
In your app/config/parameters.yml
# This file is auto-generated during the composer install
parameters:
database_driver: pdo_mysql
database_host: 127.0.0.1
database_port: 3306
database_name: symfony
database_user: root
database_password: "your_password"
mailer_transport: smtp
mailer_host: 127.0.0.1
mailer_user: null
mailer_password: null
locale: en
secret: ThisTokenIsNotSoSecretChangeIt
The value of database_password
should be within double or single quotes as in: "your_password"
or 'your_password'
.
I have seen most of users experiencing this error because they are using password with leading zero or numeric values.
The best security practice is not to store the password at all (not even encrypted), but to store the salted hash (with a unique salt per password) of the encrypted password.
That way it is (practically) impossible to retrieve a plaintext password.
You can use a Union.
This will return the results of the queries in separate rows.
First you must make sure that both queries return identical columns.
Then you can do :
SELECT tableA.Id, tableA.Name, [tableB].Username AS Owner, [tableB].ImageUrl, [tableB].CompanyImageUrl, COUNT(tableD.UserId) AS Number
FROM tableD
RIGHT OUTER JOIN [tableB]
INNER JOIN tableA ON [tableB].Id = tableA.Owner ON tableD.tableAId = tableA.Id
GROUP BY tableA.Name, [tableB].Username, [tableB].ImageUrl, [tableB].CompanyImageUrl
UNION
SELECT tableA.Id, tableA.Name, '' AS Owner, '' AS ImageUrl, '' AS CompanyImageUrl, COUNT([tableC].Id) AS Number
FROM
[tableC]
RIGHT OUTER JOIN tableA ON [tableC].tableAId = tableA.Id GROUP BY tableA.Id, tableA.Name
As has been mentioned, both queries return quite different data. You would probably only want to do this if both queries return data that could be considered similar.
SO
You can use a Join
If there is some data that is shared between the two queries. This will put the results of both queries into a single row joined by the id, which is probably more what you want to be doing here...
You could do :
SELECT tableA.Id, tableA.Name, [tableB].Username AS Owner, [tableB].ImageUrl, [tableB].CompanyImageUrl, COUNT(tableD.UserId) AS NumberOfUsers, query2.NumberOfPlans
FROM tableD
RIGHT OUTER JOIN [tableB]
INNER JOIN tableA ON [tableB].Id = tableA.Owner ON tableD.tableAId = tableA.Id
INNER JOIN
(SELECT tableA.Id, COUNT([tableC].Id) AS NumberOfPlans
FROM [tableC]
RIGHT OUTER JOIN tableA ON [tableC].tableAId = tableA.Id
GROUP BY tableA.Id, tableA.Name) AS query2
ON query2.Id = tableA.Id
GROUP BY tableA.Name, [tableB].Username, [tableB].ImageUrl, [tableB].CompanyImageUrl
You could also use negative margins:

Tomcat usually does not add classes in src/test/java
to the classpath. They are missing if you run tomcat in scope test. To order tomcat to respect classes in test, use -Dmaven.tomcat.useTestClasspath=true
or add
<properties>
<maven.tomcat.useTestClasspath>true</maven.tomcat.useTestClasspath>
</properties>
To your pom.xml
.
You can declare columns/variables as varchar2(n CHAR) and varchar2(n byte).
n CHAR means the variable will hold n characters. In multi byte character sets you don't always know how many bytes you want to store, but you do want to garantee the storage of a certain amount of characters.
n bytes means simply the number of bytes you want to store.
varchar is deprecated. Do not use it. What is the difference between varchar and varchar2?
If, like me, you would just prefer people didn't click out to youtube using the logo, one option is to use a player like jwplayer. Using jwplayer the logo is still there just unclickable.
My issue was, i am unable to create a view with my "scott" user in oracle 11g edition. So here is my solution for this
Error in my case
SQL>create view v1 as select * from books where id=10;
insufficient privileges.
Solution
1)open your cmd and change your directory to where you install your oracle database. in my case i was downloaded in E drive so my location is E:\app\B_Amar\product\11.2.0\dbhome_1\BIN> after reaching in the position you have to type sqlplus sys as sysdba
E:\app\B_Amar\product\11.2.0\dbhome_1\BIN>sqlplus sys as sysdba
2) Enter password: here you have to type that password that you give at the time of installation of oracle software.
3) Here in this step if you want create a new user then you can create otherwise give all the privileges to existing user.
for creating new user
SQL> create user abc identified by xyz;
here abc is user and xyz is password.
giving all the privileges to abc user
SQL> grant all privileges to abc;
grant succeeded.
if you are seen this message then all the privileges are giving to the abc user.
4) Now exit from cmd, go to your SQL PLUS and connect to the user i.e enter your username & password.Now you can happily create view.
In My case
in cmd E:\app\B_Amar\product\11.2.0\dbhome_1\BIN>sqlplus sys as sysdba
SQL> grant all privileges to SCOTT;
grant succeeded.
Now I can create views.
git reset --hard 1258f0d0aae
But be careful, if the descendant commits between 1258f0d0aae
and HEAD
are not referenced in other branches it'll be tedious (but not impossible) to recover them, so you'd better to create a "backup" branch at current HEAD
, checkout master
, and reset to the commit you want.
Also, be sure that you don't have uncommitted changes before a reset --hard
, they will be truly lost (no way to recover).
As mentioned by tripleee in the question comments , use moreutils ifne
(if input not empty).
In this case we want ifne -n
which negates the test:
ls -A /tmp/empty | ifne -n command-to-run-if-empty-input
The advantage of this over many of the another answers when the output of the initial command is non-empty. ifne
will start writing it to STDOUT straight away, rather than buffering the entire output then writing it later, which is important if the initial output is slowly generated or extremely long and would overflow the maximum length of a shell variable.
There are a few utils in moreutils that arguably should be in coreutils -- they're worth checking out if you spend a lot of time living in a shell.
In particular interest to the OP may be dirempty/exists
tool which at the time of writing is still under consideration, and has been for some time (it could probably use a bump).
The fetchSize
parameter is a hint to the JDBC driver as to many rows to fetch in one go from the database. But the driver is free to ignore this and do what it sees fit. Some drivers, like the Oracle one, fetch rows in chunks, so you can read very large result sets without needing lots of memory. Other drivers just read in the whole result set in one go, and I'm guessing that's what your driver is doing.
You can try upgrading your driver to the SQL Server 2008 version (which might be better), or the open-source jTDS driver.
For setting up path in Mac two methods can be followed.
Export path variable in ~/.profile_bashrc
as
export VARIABLE_NAME = $(PATH_VALUE)
AND source the the path. Its simple and stable.
You can set any path variable
by Mac terminal
or in linux
also.

Thank you Konstantin, it worked like a charm with few nuances. For some reason, specifying main class as part of jar manifest did not quite work and it wanted the mainClassName attribute instead. Here is a snippet from build.gradle that includes everything to make it work:
plugins {
id 'java'
id 'com.github.johnrengelman.shadow' version '1.2.2'
}
...
...
apply plugin: 'application'
apply plugin: 'com.github.johnrengelman.shadow'
...
...
mainClassName = 'com.acme.myapp.MyClassMain'
...
...
...
shadowJar {
baseName = 'myapp'
}
After running gradle shadowJar you get myapp-{version}-all.jar in your build folder which can be run as java -jar myapp-{version}-all.jar.
This may not be the answer you are looking for, but may help others whose jquery is not working properly, or working sometimes and not at other times.
This could be because your jquery has not yet loaded and you have started to interact with the page. Either put jquery on top in head (probably not a very great idea) or use a loader or spinner to stop the user from interacting with the page until the entire jquery has loaded.
In my case, I replaced the src taq using:
$('#gmap_canvas').attr('src', newSrc);
_x000D_
Private Sub cmdInsertRow_Click()
Dim lRow As Long
Dim lRsp As Long
On Error Resume Next
lRow = Selection.Row()
lRsp = MsgBox("Insert New row above " & lRow & "?", _
vbQuestion + vbYesNo)
If lRsp <> vbYes Then Exit Sub
Rows(lRow).Select
Selection.Copy
Rows(lRow + 1).Select
Selection.Insert Shift:=xlDown
Application.CutCopyMode = False
'Paste formulas and conditional formatting in new row created
Rows(lRow).PasteSpecial Paste:=xlPasteFormulas, Operation:=xlNone
End Sub
This is what I use. Tested and working,
Thanks,
If you want them on separate lines do what Balon said. If you want them on the same lines, do:
<td>
<div style="float:left;width:50%;">this is left</div>
<div style="float:right;width:50%;">this is right</div>
</td>
Use the find command,
find . -type f -name "*John*"
fill_parent
(deprecated) = match_parent
The border of the child view expands to match the border of the parent view.
wrap_content
The border of the child view wraps snugly around its own content.
Here are some images to make things more clear. The green and red are TextViews
. The white is a LinearLayout
showing through.
Every View
(a TextView
, an ImageView
, a Button
, etc.) needs to set the width
and the height
of the view. In the xml layout file, that might look like this:
android:layout_width="wrap_content"
android:layout_height="match_parent"
Besides setting the width and height to match_parent
or wrap_content
, you could also set them to some absolute value:
android:layout_width="100dp"
android:layout_height="200dp"
Generally that is not as good, though, because it is not as flexible for different sized devices. After you have understood wrap_content
and match_parent
, the next thing to learn is layout_weight
.

The explanation in this answer assumes there is no margin or padding. But even if there is, the basic concept is still the same. The view border/spacing is just adjusted by the value of the margin or padding.
Build lists of matched lines - several flavors:
def lines_that_equal(line_to_match, fp):
return [line for line in fp if line == line_to_match]
def lines_that_contain(string, fp):
return [line for line in fp if string in line]
def lines_that_start_with(string, fp):
return [line for line in fp if line.startswith(string)]
def lines_that_end_with(string, fp):
return [line for line in fp if line.endswith(string)]
Build generator of matched lines (memory efficient):
def generate_lines_that_equal(string, fp):
for line in fp:
if line == string:
yield line
Print all matching lines (find all matches first, then print them):
with open("file.txt", "r") as fp:
for line in lines_that_equal("my_string", fp):
print line
Print all matching lines (print them lazily, as we find them)
with open("file.txt", "r") as fp:
for line in generate_lines_that_equal("my_string", fp):
print line
Generators (produced by yield) are your friends, especially with large files that don't fit into memory.
Obviously there's a lot of different causes and thus a lot of solutions for this problem. To throw mine into the mix, we upgraded an assembly (System.Net.Http) that was previously directly referenced in our Web project to a version managed by NuGet. This removed the direct reference within that project, but our Test project still contained the direct reference. Upgrading both projects to use the NuGet-managed assembly resolved the issue.
If you want to guard against non-terminated strings, which can cause all sorts of problems, copy your string like this:
char array1[18] = {"abcdefg"};
char array2[18];
size_t destination_size = sizeof (array2);
strncpy(array2, array1, destination_size);
array2[destination_size - 1] = '\0';
That last line is actually important, because strncpy()
does not always null terminate strings. (If the destination buffer is too small to contain the whole source string, sntrcpy() will not null terminate the destination string.)
The manpage for strncpy() even states "Warning: If there is no null byte among the first n bytes of src, the string placed in dest will not be null-terminated."
The reason strncpy() behaves this somewhat odd way, is because it was not actually originally intended as a safe way to copy strings.
Another way is to use snprintf() as a safe replacement for strcpy():
snprintf(array2, destination_size, "%s", array1);
(Thanks jxh for the tip.)
You just change your application version like 4.0 to 4.6 and publish those code.
Also add below code lines:
httpRequest.ProtocolVersion = HttpVersion.Version10;
ServicePointManager.Expect100Continue = true;
ServicePointManager.SecurityProtocol = SecurityProtocolType.Ssl3 | SecurityProtocolType.Tls12 | SecurityProtocolType.Tls11 | SecurityProtocolType.Tls;

Usually, if you have big python objects it's quite hard to format them. I personally prefer using some tools for that.
Here is python-beautifier - www.cleancss.com/python-beautify that instantly turns your data into customizable style.
<?php
$first = reset($arr_nav); // Get the first element
$last = end($arr_nav); // Get the last element
// Ensure that we have a first element and that it's an array
if(is_array($first)) {
$first['class'] = 'first';
}
// Ensure we have a last element and that it differs from the first
if(is_array($last) && $last !== $first) {
$last['class'] = 'last';
}
Now you could just echo the class inside you html-generator. Would probably need some kind of check to ensure that the class is set, or provide a default empty class to the array.

It's an extension of twitter bootstrap popover and will solve the problem very simply.
From a programmatic standpoint, for the client it's packaging up parameters and appending them onto the url and conducting a POST vs. a GET. On the server-side, it's evaluating inbound parameters from the querystring instead of the posted bytes. Basically, it's a wash.
Where there could be advantages/disadvantages might be in how specific client platforms work with POST and GET routines in their networking stack, as well as how the web server deals with those requests. Depending on your implementation, one approach may be more efficient than the other. Knowing that would guide your decision here.
Nonetheless, from a programmer's perspective, I prefer allowing either a POST with all parameters in the body, or a GET with all params on the url, and explicitly ignoring url parameters with any POST request. It avoids confusion.

Analogous to @Resh32, but without the need to use the USE
statement:
SELECT TABLE_NAME,
COLUMN_NAME,
CONSTRAINT_NAME,
REFERENCED_TABLE_NAME,
REFERENCED_COLUMN_NAME
FROM INFORMATION_SCHEMA.KEY_COLUMN_USAGE
WHERE TABLE_SCHEMA = "database_name"
AND TABLE_NAME = "table_name"
AND REFERENCED_COLUMN_NAME IS NOT NULL;
Useful, e.g. using the ORM.
onclick = "setTimeout(function() { document.getElementById('div1').style.display='none';document.getElementById('div2').style.display='none'}, 1000)"
Change 1000 to the number of milliseconds you want to delay.
"Add a reference to MySql.Data.dll" means you need to add a library reference to the downloaded connector. The IDE will link the database connection library with your application when it compiles.
I downloaded the binary (no installer) zip package from the MySQL web site, extracted onto the desktop, and did the following:
using MySql.Data.MySqlClient;
. If you've added the reference correctly, IntelliSense should offer to complete this for you.I love this answer. However, since next()
raise a StopIteration
exception when there are no items,
i would use the following snippet to avoid an exception:
a = []
item = next((x for x in a), None)
For example,
a = []
item = next(x for x in a)
Will raise a StopIteration
exception;
Traceback (most recent call last):
File "<stdin>", line 1, in <module>

You could use the bootstrap grid system :
<div class="col-md-6 form-group">
<label for="textbox1">Label1</label>
<input class="form-control" id="textbox1" type="text"/>
</div>
<div class="col-md-6 form-group">
<label for="textbox2">Label2</label>
<input class="form-control" id="textbox2" type="text"/>
</div>
<span class="clearfix">
http://getbootstrap.com/css/#grid
Is that what you want to achieve?
I don't understand why you're using FirstOrDefault(x=> x.ID == key)
when this could retrieve results much faster if you use Find(key)
. If you are querying with the Primary key of the table, the rule of thumb is to always use Find(key)
. FirstOrDefault
should be used for predicate stuff like (x=> x.Username == username)
etc.
this did not deserve a downvote as the heading of the question was not specific to linq on DB or Linq to List/IEnumerable etc.
Here is the BESTEST way to send emails using PHPmailer library, this is the only method that works for me.
require_once 'mailer/class.phpmailer.php';
$mail = new PHPMailer(); // create a new object
$mail->IsSMTP(); // enable SMTP
$mail->SMTPDebug = 1; // debugging: 1 = errors and messages, 2 = messages only
$mail->SMTPAuth = true; // authentication enabled
$mail->SMTPSecure = 'ssl'; // secure transfer enabled REQUIRED for GMail
$mail->Host = "smtp.gmail.com";
$mail->Port = 465; // or 587
$mail->IsHTML(true);
$mail->Username = "[email protected]";
$mail->Password = "xxxxxxx";
$mail->SetFrom("[email protected]");
$mail->AddAddress($to);
$logfile = dirname(dirname(__FILE__)) . '/mail.log';
try {
$mail->Body = $message;
$mail->Subject = $subject;
file_put_contents($logfile, "Content: \n", FILE_APPEND);
file_put_contents($logfile, $message . "\n\n", FILE_APPEND);
if(!$mail->Send()) {
echo "Mailer Error: " . $mail->ErrorInfo;
} else {
echo "Email has been sent";
}
} catch (Exception $e) {
#print_r($e->getMessage());
file_put_contents($logfile, "Error: \n", FILE_APPEND);
file_put_contents($logfile, $e->getMessage() . "\n", FILE_APPEND);
file_put_contents($logfile, $e->getTraceAsString() . "\n\n", FILE_APPEND);
}
I know this is old, but I would like to suggest using a linear-gradient to achieve the same effect instead of margin offset. This is will maintain any content at its original place.

Take a look at this for more detail. It refers to how Apache handles multiple requests. Preforking, which is the default, starts a number of Apache processes (2 by default here, though I believe one can configure this through httpd.conf). Worker MPM will start a new thread per request, which I would guess, is more memory efficient. Historically, Apache has used prefork, so it's a better-tested model. Threading was only added in 2.0.
Only this worked for me:
#container:hover .cube { background-color: yellow; }
Where .cube
is CssClass of the #cube
.
Tested in Firefox, Chrome and Edge.
This is to make the variable of Optional type. Otherwise declared variables shows "undefined" if this variable is not used.
export interface ISearchResult {
title: string;
listTitle:string;
entityName?: string,
lookupName?:string,
lookupId?:string
}
I think the good practice may be something like this;
import subprocess
cmd = 'python script.py'
p = subprocess.Popen(cmd, stdout=subprocess.PIPE, shell=True)
out, err = p.communicate()
result = out.split('\n')
for lin in result:
if not lin.startswith('#'):
print(lin)
according to documentation The subprocess module allows you to spawn new processes, connect to their input/output/error pipes, and obtain their return codes. This module intends to replace several older modules and functions:
os.system
os.spawn*
os.popen*
popen2.*
commands.*
Use communicate() rather than .stdin.write, .stdout.read or .stderr.read to avoid deadlocks due to any of the other OS pipe buffers filling up and blocking the child process. Read Here
Doug answered my question... But I'll explain what my problem was exactly, and how Doug helped me solve my problem which you could be encountering.
I call jquery $.post
and am replacing my div with my partial view, like so.
function AddNewAddress (paramvalue) {
$.post(url, { param: paramvalue}, function(d) {
$('#myDiv').replaceWith(d);
});
}
When doing so, for some reason when stepping into my model my selected value affiliated property was never set, only until I stepped into the view it came into scope.
So, What I had before
@Html.DropDownListUnobtrusiveFor(model => model.CustomerAddresses[i].YearsAtAddress, Model.CustomerAddresses[i].YearsAtAddressSelectList, new {onchange = "return Address.AddNewAddress(this,'" + @Url.Action("AddNewAddress", "Address") + "'," + i + ")"})
however even though Model.CustomerAddresses[i].YearsAtAddressSelectList, was set... it didn't set the selected value.
So after....
@Html.DropDownListUnobtrusiveFor(model => model.CustomerAddresses[i].YearsAtAddress, new SelectList(Model.CustomerAddresses[i].YearsAtAddressSelectList, "Value", "Text", Model.CustomerAddresses[i].YearsAtAddress), new { onchange = "return Address.AddNewAddress(this,'" + @Url.Action("AddNewAddress", "Address") + "'," + i + ")" })
and it worked!
I decided not to use DropDownListFor
as it has problem when using unobtrusive validation, which is why i reference the following if your curious in a class classed

I coudn't get any gain from transactions until I raised cache_size to a higher value i.e. PRAGMA cache_size=10000;
Same thing is happening for me. And yes, as @Joao Leme said, it seems it is related to a user bookmarking a site to their device homescreen.
However, I noticed that even though there is an error in the log, it's happening behind the scenes and the user never sees the error. I assume the device makes a request for the touch-icon specific to its resolution (which isn't there) until defaulting to the general apple-touch-icon
or apple-touch-icon-precomposed
, if present, or else generates a small screenshot of the current page.
FWIW, put the icons in the /public directory.
Use this..
$res_arr_values = array();
while ($row = mysql_fetch_array($result, MYSQL_ASSOC))
{
$res_arr_values[] = $row;
}
I posted this answer for similar question.
Don't reinvent the wheel. I've used a number of libraries and the fastest and most flexible I have come across is: C++ String Toolkit Library.
Here is an example of how to use it that I've posted else where on the stackoverflow.
#include <iostream>
#include <vector>
#include <string>
#include <strtk.hpp>
const char *whitespace = " \t\r\n\f";
const char *whitespace_and_punctuation = " \t\r\n\f;,=";
int main()
{
{ // normal parsing of a string into a vector of strings
std::string s("Somewhere down the road");
std::vector<std::string> result;
if( strtk::parse( s, whitespace, result ) )
{
for(size_t i = 0; i < result.size(); ++i )
std::cout << result[i] << std::endl;
}
}
{ // parsing a string into a vector of floats with other separators
// besides spaces
std::string s("3.0, 3.14; 4.0");
std::vector<float> values;
if( strtk::parse( s, whitespace_and_punctuation, values ) )
{
for(size_t i = 0; i < values.size(); ++i )
std::cout << values[i] << std::endl;
}
}
{ // parsing a string into specific variables
std::string s("angle = 45; radius = 9.9");
std::string w1, w2;
float v1, v2;
if( strtk::parse( s, whitespace_and_punctuation, w1, v1, w2, v2) )
{
std::cout << "word " << w1 << ", value " << v1 << std::endl;
std::cout << "word " << w2 << ", value " << v2 << std::endl;
}
}
return 0;
}
So, in an ideal world you'd have a spec for all pages in your site. You would also have a test infrastructure that could hit all your pages to test them.
You're presumably not in an ideal world. Why not do this...?
Create a mapping between the well known old URLs and the new ones. Redirect when you see an old URL. I'd possibly consider presenting a "this page has moved, it's new url is XXX, you'll be redirected shortly".
If you have no mapping, present a "sorry - this page has moved. Here's a link to the home page" message and redirect them if you like.
Log all redirects - especially the ones with no mapping. Over time, add mappings for pages that are important.
The following CSS changes in bold (plus a bunch of content in the columns to test scrolling) will work. See the result in this Pen.
.content { flex: 1; display: flex; height: 1px; }
.column { padding: 20px; border-right: 1px solid #999; overflow: auto; }
The trick seems to be that a scrollable panel needs to have a height
literally set somewhere (in this case, via its parent), not just determined by flexbox. So even height: 1px
works. The flex-grow:1
will still size the panel to fit properly.
Just dot is working. The doctype makes a difference however as sometimes the ./ is fine as well.
<a href=".">Link to this folder</a>
Use the CAST
to the new DATE
data type in SQL Server 2008 to compare just the date portion:
IF CAST(DateField1 AS DATE) = CAST(DateField2 AS DATE)
I had a similar Problem as @CraigWalker on debian: My database was in a state where a DROP TABLE
failed because it couldn't find the table, but a CREATE TABLE
also failed because MySQL thought the table still existed. So the broken table still existed somewhere although it wasn't there when I looked in phpmyadmin.
I created this state by just copying the whole folder that contained a database with some MyISAM
and some InnoDB
tables
cp -a /var/lib/mysql/sometable /var/lib/mysql/test
(this is not recommended!)
All InnoDB tables where not visible in the new database test
in phpmyadmin.
sudo mysqladmin flush-tables
didn't help either.
My solution: I had to delete the new test database with drop database test
and copy it with mysqldump
instead:
mysqldump somedatabase -u username -p -r export.sql
mysql test -u username -p < export.sql
This is what I needed to disable scrollbars while preserving scroll in Firefox, Chrome and Edge in :
@-moz-document url-prefix() { /* Disable scrollbar Firefox */
html{
scrollbar-width: none;
}
}
body {
margin: 0; /* remove default margin */
scrollbar-width: none; /* Also needed to disable scrollbar Firefox */
-ms-overflow-style: none; /* Disable scrollbar IE 10+ */
overflow-y: scroll;
}
body::-webkit-scrollbar {
width: 0px;
background: transparent; /* Disable scrollbar Chrome/Safari/Webkit */
}
The order of items in the PATH matters. If there are multiple entries for various java installations, the first one in your PATH will be used.
I have had similar issues after installing a product, like Oracle, that puts it's JRE at the beginning of the PATH.
Ensure that the JDK you want to be loaded is the first entry in your PATH (or at least that it appears before C:\Program Files\Java\jre6\bin
appears).
You could also use the php native funcion get_browser()
IMPORTANT NOTE: You should have a browscap.ini file.
The overall dimensions of a range are in its Width
and Height
properties.
Dim r As Range
Set r = ActiveSheet.Range("A4:H12")
Debug.Print r.Width
Debug.Print r.Height

*any colour you wish *object being declared earlier
I think it makes clear with the namespace, as we can create our own attributes and if the user specified attribute is the same as the Android one it avoid the conflict of the namespace.
What about having a live validation on the textbox, and once it goes over 2000 (or whatever the maximum threshold is) then display 'This email is too long to be completed in the browser, please <span class="launchEmailClientLink">launch what you have in your email client</span>
'
To which I'd have
.launchEmailClientLink {
cursor: pointer;
color: #00F;
}
and jQuery this into your onDomReady
$('.launchEmailClientLink').bind('click',sendMail);
just add 'staticmethod' decorator to function and problem is fixed
class foo(object):
@staticmethod
def foodo(thing=None, thong='not underwear'):
print thing if thing else "nothing"
print 'a thong is',thong
This solution assumes that you want to draw the image in a picture box and that the image orientation will follow the mouse movements over this picture box. No image is assigned to the picture box. Instead I'm getting the image from a project resource.
private float _angle;
public Form1()
{
InitializeComponent();
}
private void PictureBox_MouseMove(object sender, MouseEventArgs e)
{
(float centerX, float centerY) = GetCenter(pictureBox1.ClientRectangle);
_angle = (float)(Math.Atan2(e.Y - centerY, e.X - centerX) * 180.0 / Math.PI);
pictureBox1.Invalidate(); // Triggers redrawing
}
private void PictureBox_Paint(object sender, PaintEventArgs e)
{
Bitmap image = Properties.Resources.ExampleImage;
float scale = (float)pictureBox1.Width / image.Width;
(float centerX, float centerY) = GetCenter(e.ClipRectangle);
e.Graphics.TranslateTransform(centerX, centerY);
e.Graphics.RotateTransform(_angle);
e.Graphics.TranslateTransform(-centerX, -centerY);
e.Graphics.ScaleTransform(scale, scale);
e.Graphics.DrawImage(image, 0, 0);
}
// Uses C# 7.0 value tuples / .NET Framework 4.7.
// For previous versions, return a PointF instead.
private static (float, float) GetCenter(Rectangle rect)
{
float centerX = (rect.Left + rect.Right) * 0.5f;
float centerY = (rect.Top + rect.Bottom) * 0.5f;
return (centerX, centerY);
}
Make sure to to select the mouse event handlers PictureBox_MouseMove
and PictureBox_Paint
in properties window of the picture box for these events, after you copy/pasted this code into the form.
Note: You could also use a simple Panel
or any other control, like a label; however, the PictureBox
has the advantage to use double buffering by default, which eliminates flickering.
You need to include jQueryUI for the extended easing options.
I think there may be an option to only include the easing in the download, or at least just the base library plus easing.
It's the '+' operator at the beginning of the line that trips things up (not just that you are using two '+' operators consecutively). The '+' operator can be used at the end of lines, but not at the beginning.
This works:
ggplot(combined.data, aes(x = region, y = expression, fill = species)) +
geom_boxplot()
The does not:
ggplot(combined.data, aes(x = region, y = expression, fill = species))
+ geom_boxplot()
*Error in + geom_boxplot():
invalid argument to unary operator*
You also can't use two '+' operators, which in this case you've done. But to fix this, you'll have to selectively remove those at the beginning of lines.
For me this works to counter the difference between zoom and scale transform, adjust for the intended origin desired:
zoom: 0.5;
-ms-zoom: 0.5;
-webkit-zoom: 0.5;
-moz-transform: scale(0.5,0.5);
-moz-transform-origin: left center;

When filtering a DataFrame with string values, I find that the pyspark.sql.functions
lower
and upper
come in handy, if your data could have column entries like "foo" and "Foo":
import pyspark.sql.functions as sql_fun
result = source_df.filter(sql_fun.lower(source_df.col_name).contains("foo"))
The plugin that @DarinDimitrov posted, jquery-mousewheel
, is broken with jQuery 3+. It would be more advisable to use jquery-wheel
which works with jQuery 3+.
If you don't want to go the jQuery route, MDN highly cautions using the mousewheel
event as it's nonstandard and unsupported in many places. It instead says that you should use the wheel
event as you get much more specificity over exactly what the values you're getting mean. It's supported by most major browsers.
I thought that my first answer gives the correct day of week as a number between 0 and 6. However, because you had not indicated why this answer does not give the result you want, I can only guess the reason.
The Batch file below create a log file each day with a digit in the name, 0=Sunday, 1=Monday, etc... The program assume that echo %date%
show the date in MM/DD/YYYY format; if this is not the case, just change the position of mm and dd variables in the for
command.
@echo off
for /F "tokens=1-3 delims=/" %%a in ("%date%") do set /A mm=10%%a %% 100, dd=10%%b %% 100, yy=%%c
if %mm% lss 3 set /A mm+=12, yy-=1
set /A a=yy/100, b=a/4, c=2-a+b, e=36525*(yy+4716)/100, f=306*(mm+1)/10, dow=(c+dd+e+f-1523)%%7
echo Today log data > Day-%dow%.txt
If this is not what you want, please indicate the problem so I can fix it.
EDIT: The version below get date parts independent of locale settings:
@echo off
for /F "skip=1 tokens=2-4 delims=(-/)" %%A in ('date ^< NUL') do (
for /F "tokens=1-3 delims=/" %%a in ("%date%") do (
set %%A=%%a
set %%B=%%b
set %%C=%%c
)
)
set /A mm=10%mm% %% 100, dd=10%dd% %% 100
if %mm% lss 3 set /A mm+=12, yy-=1
set /A a=yy/100, b=a/4, c=2-a+b, e=36525*(yy+4716)/100, f=306*(mm+1)/10,
dow=(c+dd+e+f-1523)%%7
echo Today log data > Day-%dow%.txt
EDIT: The version below insert day of week as 3-letter short name:
@echo off
for /F "skip=1 tokens=2-4 delims=(-/)" %%A in ('date ^< NUL') do (
for /F "tokens=1-3 delims=/" %%a in ("%date%") do (
set %%A=%%a
set %%B=%%b
set %%C=%%c
)
)
set /A mm=10%mm% %% 100, dd=10%dd% %% 100
if %mm% lss 3 set /A mm+=12, yy-=1
set /A a=yy/100, b=a/4, c=2-a+b, e=36525*(yy+4716)/100, f=306*(mm+1)/10,
dow=(c+dd+e+f-1523)%%7 + 1
for /F "tokens=%dow%" %%a in ("Sun Mon Tue Wed Thu Fri Sat") do set dow=%%a

I'm just starting some string manipulations and found this question. I was probably trying to do something like the OP, "usual me". The previous answers did not clear up my confusion, but after thinking a little about it I finally "got it".
As long as a
, b
, c
, d
, and e
have the same value, they reference to the same place. Memory is saved. As soon as the variable start to have different values, they get start to have different references. My learning experience came from this code:
import copy
a = 'hello'
b = str(a)
c = a[:]
d = a + ''
e = copy.copy(a)
print map( id, [ a,b,c,d,e ] )
print a, b, c, d, e
e = a + 'something'
a = 'goodbye'
print map( id, [ a,b,c,d,e ] )
print a, b, c, d, e
The printed output is:
[4538504992, 4538504992, 4538504992, 4538504992, 4538504992]
hello hello hello hello hello
[6113502048, 4538504992, 4538504992, 4538504992, 5570935808]
goodbye hello hello hello hello something

It looks like you are using the HttpClient API, which I know nothing about, but you could write something similar to this using core Java.
try {
HttpURLConnection con = (HttpURLConnection) new URL(url).openConnection();
con.setRequestMethod("HEAD");
con.setConnectTimeout(5000); //set timeout to 5 seconds
return (con.getResponseCode() == HttpURLConnection.HTTP_OK);
} catch (java.net.SocketTimeoutException e) {
return false;
} catch (java.io.IOException e) {
return false;
}
So imagine everyone is trying to go to the bathroom and there's only a certain number of keys to the bathroom. Now if there's not enough keys left, that person needs to wait. So think of semaphore as representing those set of keys available for bathrooms (the system resources) that different processes (bathroom goers) can request access to.
Now imagine two processes trying to go to the bathroom at the same time. That's not a good situation and semaphores are used to prevent this. Unfortunately, the semaphore is a voluntary mechanism and processes (our bathroom goers) can ignore it (i.e. even if there are keys, someone can still just kick the door open).
There are also differences between binary/mutex & counting semaphores.
Check out the lecture notes at http://www.cs.columbia.edu/~jae/4118/lect/L05-ipc.html.
another solution that works fine is to create empty list as a reference empty list.
empt_list = []
for example you have a list as a_list = [1,2,3]
. To clear it just make the following:
a_list = list(empt_list)
this will make a_list
an empty list just like the empt_list
.
You should avoid using pool.getConnection()
if you can. If you call pool.getConnection()
, you must call connection.release()
when you are done using the connection. Otherwise, your application will get stuck waiting forever for connections to be returned to the pool once you hit the connection limit.
For simple queries, you can use pool.query()
. This shorthand will automatically call connection.release()
for you—even in error conditions.
function doSomething(cb) {
pool.query('SELECT 2*2 "value"', (ex, rows) => {
if (ex) {
cb(ex);
} else {
cb(null, rows[0].value);
}
});
}
However, in some cases you must use pool.getConnection()
. These cases include:
If you must use pool.getConnection()
, ensure you call connection.release()
using a pattern similar to below:
function doSomething(cb) {
pool.getConnection((ex, connection) => {
if (ex) {
cb(ex);
} else {
// Ensure that any call to cb releases the connection
// by wrapping it.
cb = (cb => {
return function () {
connection.release();
cb.apply(this, arguments);
};
})(cb);
connection.beginTransaction(ex => {
if (ex) {
cb(ex);
} else {
connection.query('INSERT INTO table1 ("value") VALUES (\'my value\');', ex => {
if (ex) {
cb(ex);
} else {
connection.query('INSERT INTO table2 ("value") VALUES (\'my other value\')', ex => {
if (ex) {
cb(ex);
} else {
connection.commit(ex => {
cb(ex);
});
}
});
}
});
}
});
}
});
}
I personally prefer to use Promise
s and the useAsync()
pattern. This pattern combined with async
/await
makes it a lot harder to accidentally forget to release()
the connection because it turns your lexical scoping into an automatic call to .release()
:
async function usePooledConnectionAsync(actionAsync) {
const connection = await new Promise((resolve, reject) => {
pool.getConnection((ex, connection) => {
if (ex) {
reject(ex);
} else {
resolve(connection);
}
});
});
try {
return await actionAsync(connection);
} finally {
connection.release();
}
}
async function doSomethingElse() {
// Usage example:
const result = await usePooledConnectionAsync(async connection => {
const rows = await new Promise((resolve, reject) => {
connection.query('SELECT 2*4 "value"', (ex, rows) => {
if (ex) {
reject(ex);
} else {
resolve(rows);
}
});
});
return rows[0].value;
});
console.log(`result=${result}`);
}
From How to tell if path is file or directory:
// get the file attributes for file or directory
FileAttributes attr = File.GetAttributes(@"c:\Temp");
//detect whether its a directory or file
if ((attr & FileAttributes.Directory) == FileAttributes.Directory)
MessageBox.Show("Its a directory");
else
MessageBox.Show("Its a file");
Per the comments below, if you are on .NET 4.0 or later (and maximum performance is not critical) you can write the code in a cleaner way:
// get the file attributes for file or directory
FileAttributes attr = File.GetAttributes(@"c:\Temp");
if (attr.HasFlag(FileAttributes.Directory))
MessageBox.Show("Its a directory");
else
MessageBox.Show("Its a file");
This question is probably best answered by taking a look at historical practice.
In the past, I've seen gaming console emulators on PC for the PlayStation & SEGA.
Simulators are commonplace when referring to software that tries to mimic real life actions, such as driving or flying. Gran Turismo and Microsoft Flight Simulator spring to mind as classic examples of simulators.
As for the linguistic difference, emulation usually refers to the action of copying someone's (or something's) praiseworthy characteristics or behaviors. Emulation is distinct from imitation, in which a person is copied for the purpose of mockery.
The linguistic meaning of the verb 'simulation' is essentially to pretend or mimic someone or something.

If you want to force the factory function usage, name your struct (your class) with the first character in lowercase. Then, it won't be possible to instantiate directly the struct, the factory method will be required.
This visibility based on first character lower/upper case work also for struct field and for the function/method. If you don't want to allow external access, use lower case.
If you want to start with a file you can do this
[xml]$cn = Get-Content config.xml
$cn.xml.Section.BEName
There is also a shorthand of doing this:
NSArray *persons = @[person1, person2, person3];
It's equivalent to
NSArray *persons = [NSArray arrayWithObjects:person1, person2, person3, nil];
As iiFreeman said, you still need to do proper memory management if you're not using ARC.
Just throwing another solution in the mix...
Try jq
, a lightweight and flexible command-line JSON processor:
jq length /tmp/test.json
Prints the length of the array of objects.
HTML
create div with id='dvFile'
;
create a button
;
onclick
of that button calling function add_more()
JavaScript
function add_more() {
var txt = "<br><input type=\"file\" name=\"item_file[]\">";
document.getElementById("dvFile").innerHTML += txt;
}
PHP
if(count($_FILES["item_file"]['name'])>0)
{
//check if any file uploaded
$GLOBALS['msg'] = ""; //initiate the global message
for($j=0; $j < count($_FILES["item_file"]['name']); $j++)
{ //loop the uploaded file array
$filen = $_FILES["item_file"]['name']["$j"]; //file name
$path = 'uploads/'.$filen; //generate the destination path
if(move_uploaded_file($_FILES["item_file"]['tmp_name']["$j"],$path))
{
//upload the file
$GLOBALS['msg'] .= "File# ".($j+1)." ($filen) uploaded successfully<br>";
//Success message
}
}
}
else {
$GLOBALS['msg'] = "No files found to upload"; //No file upload message
}
In this way you can add file/images, as many as required, and handle them through php script.
Just change your default port 8080 to something else like below example
SQL> begin
2 dbms_xdb.sethttpport('9090');
3 end;

Try using fetchone
:
cursor.execute("SELECT COUNT(*) from result where server_state='2' AND name LIKE '"+digest+"_"+charset+"_%'")
result=cursor.fetchone()
result
will hold a tuple with one element, the value of COUNT(*)
.
So to find the number of rows:
number_of_rows=result[0]
Or, if you'd rather do it in one fell swoop:
cursor.execute("SELECT COUNT(*) from result where server_state='2' AND name LIKE '"+digest+"_"+charset+"_%'")
(number_of_rows,)=cursor.fetchone()
PS. It's also good practice to use parametrized arguments whenever possible, because it can automatically quote arguments for you when needed, and protect against sql injection.
The correct syntax for parametrized arguments depends on your python/database adapter (e.g. mysqldb, psycopg2 or sqlite3). It would look something like
cursor.execute("SELECT COUNT(*) from result where server_state= %s AND name LIKE %s",[2,digest+"_"+charset+"_%"])
(number_of_rows,)=cursor.fetchone()
I think it's impossible to understand the other answers without covering the pitfalls and reasoning behind it.
You cannot directly cast an Integer
to a Double
object. Also Double
and Integer
are immutable objects, so you cannot modify them in any way.
Each numeric class has a primitive alternative (Double
vs double
, Integer
vs int
, ...). Note that these primitives start with a lowercase character (e.g. int
). That tells us that they aren't classes/objects. Which also means that they don't have methods. By contrast, the classes (e.g. Integer
) act like boxes/wrappers around these primitives, which makes it possible to use them like objects.
To convert a Double
to an Integer
you would need to follow this strategy:
Double
object to a primitive double
. (= "unboxing")double
to a primitive int
. (= "casting")int
back to an Integer
object. (= "boxing")// starting point
Double myDouble = Double.valueOf(10.0);
// step 1: unboxing
double dbl = myDouble.doubleValue();
// step 2: casting
int intgr = (int) dbl;
// step 3: boxing
Integer val = Integer.valueOf(intgr);
Actually there is a shortcut. You can unbox immediately from a Double
straight to a primitive int
. That way, you can skip step 2 entirely.
Double myDouble = Double.valueOf(10.0);
Integer val = Integer.valueOf(myDouble.intValue()); // the simple way
However, there are a lot of things that are not covered in the code above. The code-above is not null-safe.
Double myDouble = null;
Integer val = Integer.valueOf(myDouble.intValue()); // will throw a NullPointerException
// a null-safe solution:
Integer val = (myDouble == null)? null : Integer.valueOf(myDouble.intValue());
Now it works fine for most values. However integers have a very small range (min/max value) compared to a Double
. On top of that, doubles can also hold "special values", that integers cannot:
So, depending on the application, you may want to add some filtering to avoid nasty Exceptions.
Then, the next shortcoming is the rounding strategy. By default Java will always round down. Rounding down makes perfect sense in all programming languages. Basically Java is just throwing away some of the bytes. In financial applications you will surely want to use half-up rounding (e.g.: round(0.5) = 1
and round(0.4) = 0
).
// null-safe and with better rounding
long rounded = (myDouble == null)? 0L: Math.round(myDouble.doubleValue());
Integer val = Integer.valueOf(rounded);
You could be tempted to use auto-(un)boxing in this, but I wouldn't. If you're already stuck now, then the next examples will not be that obvious neither. If you don't understand the inner workings of auto-(un)boxing then please don't use it.
Integer val1 = 10; // works
Integer val2 = 10.0; // doesn't work
Double val3 = 10; // doesn't work
Double val4 = 10.0; // works
Double val5 = null;
double val6 = val5; // doesn't work (throws a NullPointerException)
I guess the following shouldn't be a surprise. But if it is, then you may want to read some article about casting in Java.
double val7 = (double) 10; // works
Double val8 = (Double) Integer.valueOf(10); // doesn't work
Integer val9 = (Integer) 9; // pure nonsense
Also, don't be tempted to use new Integer()
constructor (as some other answers propose). The valueOf()
methods are better because they use caching. It's a good habit to use these methods, because from time to time they will save you some memory.
long rounded = (myDouble == null)? 0L: Math.round(myDouble.doubleValue());
Integer val = new Integer(rounded); // waste of memory
I used a global action filter to remove Accept: application/xml
when the User-Agent
header contains "Chrome":
internal class RemoveXmlForGoogleChromeFilter : IActionFilter
{
public bool AllowMultiple
{
get { return false; }
}
public async Task<HttpResponseMessage> ExecuteActionFilterAsync(
HttpActionContext actionContext,
CancellationToken cancellationToken,
Func<Task<HttpResponseMessage>> continuation)
{
var userAgent = actionContext.Request.Headers.UserAgent.ToString();
if (userAgent.Contains("Chrome"))
{
var acceptHeaders = actionContext.Request.Headers.Accept;
var header =
acceptHeaders.SingleOrDefault(
x => x.MediaType.Contains("application/xml"));
acceptHeaders.Remove(header);
}
return await continuation();
}
}
Seems to work.
You can use the row_number()
function for this.
INSERT INTO PM_Ingrediants_Arrangements_Temp(AdminID, ArrangementID, IngrediantID, Sequence)
SELECT @AdminID, @ArrangementID, PM_Ingrediants.ID,
row_number() over (order by (select NULL))
FROM PM_Ingrediants
WHERE PM_Ingrediants.ID IN (SELECT ID FROM GetIDsTableFromIDsList(@IngrediantsIDs)
)
If you want to start with the maximum already in the table then do:
INSERT INTO PM_Ingrediants_Arrangements_Temp(AdminID, ArrangementID, IngrediantID, Sequence)
SELECT @AdminID, @ArrangementID, PM_Ingrediants.ID,
coalesce(const.maxs, 0) + row_number() over (order by (select NULL))
FROM PM_Ingrediants cross join
(select max(sequence) as maxs from PM_Ingrediants_Arrangement_Temp) const
WHERE PM_Ingrediants.ID IN (SELECT ID FROM GetIDsTableFromIDsList(@IngrediantsIDs)
)
Finally, you can just make the sequence
column an auto-incrementing identity column. This saves the need to increment it each time:
create table PM_Ingrediants_Arrangement_Temp ( . . .
sequence int identity(1, 1) -- and might consider making this a primary key too
. . .
)
You can loop the array with a for loop and the object properties with for-in loops.
for (var i=0; i<result.length; i++)
for (var name in result[i]) {
console.log("Item name: "+name);
console.log("Source: "+result[i][name].sourceUuid);
console.log("Target: "+result[i][name].targetUuid);
}
You should use hasOwnProperty
. For example:
myObj.hasOwnProperty('myKey');
Note: If you are using ESLint, the above may give you an error for violating the no-prototype-builtins rule, in that case the workaround is as below:
Object.prototype.hasOwnProperty.call(myObj, 'myKey');
The accepted answer is invalid with the double EXEC (only need the first EXEC):
DECLARE @returnvalue int;
EXEC @returnvalue = SP_SomeProc
PRINT @returnvalue
And you still need to call PRINT (at least in Visual Studio).
By default, it does not. However, you can use the MVCHtml5Toolkit NuGet package that has HTML helpers that can output HTML5. For your example, after installing the toolkit you can then use the following HTML helper call:
@Html.Html5TextBoxFor(m => m.Email, InputTypes.InputType.Email)
This will output the following HTML:
<input id="Email" name="Email" placeholder="E-Mail" type="Email" value="">
As can be seen, the placeholder is now correctly rendered.
Extending @oopbase's answer with return;
statement.
Let's consider a use case of traditional authentication system where we store login information into the session. On each page we check for active session like,
/* Some Import Statements here. */
if(null == session || !session.getAttribute("is_login").equals("1")) {
response.sendRedirect("http://domain.com/login");
}
// ....
session.getAttribute("user_id");
// ....
/* Some More JSP+Java+HTML code here */
It looks fine at first glance however; It has one issue. If your server has expired session due to time limit and user is trying to access the page he might get error if you have not written your code in try..catch
block or handled if(null != session.getAttribute("attr_name"))
everytime.
So by putting a return;
statement I stopped further execution and forced to redirect page to certain location.
if(null == session || !session.getAttribute("is_login").equals("1")) {
response.sendRedirect("http://domain.com/login");
return;
}
Note that Use of redirection may vary based on the requirements. Nowadays people don't use such authentication system. (Modern approach - Token Based Authentication) It's just an simple example to understand where and how to place redirection(s).
Not sure if this is more concise, but this function will also find and allow replacement of NAs (or any value you like) in selected columns of a data.table:
update.mat <- function(dt, cols, criteria) {
require(data.table)
x <- as.data.frame(which(criteria==TRUE, arr.ind = TRUE))
y <- as.matrix(subset(x, x$col %in% which((names(dt) %in% cols), arr.ind = TRUE)))
y
}
To apply it:
y[update.mat(y, c("a", "b"), is.na(y))] <- 0
The function creates a matrix of the selected columns and rows (cell coordinates) that meet the input criteria (in this case is.na == TRUE).
I tried several solutions and here is the simplest I personally found.
Dan pointed out in the comments that the original post belongs to Oleg Sych—thanks, Oleg!
Here are the instructions:
1. Add an XML file for each configuration to the project.
Typically you will have Debug
and Release
configurations so name your files App.Debug.config
and App.Release.config
. In my project, I created a configuration for each kind of environment, so you might want to experiment with that.
2. Unload project and open .csproj file for editing
Visual Studio allows you to edit .csproj files right in the editor—you just need to unload the project first. Then right-click on it and select Edit <ProjectName>.csproj.
3. Bind App.*.config files to main App.config
Find the project file section that contains all App.config
and App.*.config
references. You'll notice their build actions are set to None
:
<None Include="App.config" />
<None Include="App.Debug.config" />
<None Include="App.Release.config" />
First, set build action for all of them to Content
.
Next, make all configuration-specific files dependant on the main App.config
so Visual Studio groups them like it does designer and code-behind files.
Replace XML above with the one below:
<Content Include="App.config" />
<Content Include="App.Debug.config" >
<DependentUpon>App.config</DependentUpon>
</Content>
<Content Include="App.Release.config" >
<DependentUpon>App.config</DependentUpon>
</Content>
4. Activate transformations magic (only necessary for Visual Studio versions pre VS2017)
In the end of file after
<Import Project="$(MSBuildToolsPath)\Microsoft.CSharp.targets" />
and before final
</Project>
insert the following XML:
<UsingTask TaskName="TransformXml" AssemblyFile="$(MSBuildExtensionsPath)\Microsoft\VisualStudio\v$(VisualStudioVersion)\Web\Microsoft.Web.Publishing.Tasks.dll" />
<Target Name="CoreCompile" Condition="exists('app.$(Configuration).config')">
<!-- Generate transformed app config in the intermediate directory -->
<TransformXml Source="app.config" Destination="$(IntermediateOutputPath)$(TargetFileName).config" Transform="app.$(Configuration).config" />
<!-- Force build process to use the transformed configuration file from now on. -->
<ItemGroup>
<AppConfigWithTargetPath Remove="app.config" />
<AppConfigWithTargetPath Include="$(IntermediateOutputPath)$(TargetFileName).config">
<TargetPath>$(TargetFileName).config</TargetPath>
</AppConfigWithTargetPath>
</ItemGroup>
</Target>
Now you can reload the project, build it and enjoy App.config
transformations!
FYI
Make sure that your App.*.config
files have the right setup like this:
<?xml version="1.0" encoding="utf-8"?>
<configuration xmlns:xdt="http://schemas.microsoft.com/XML-Document-Transform">
<!--magic transformations here-->
</configuration>
There could be many reason why document.getElementById
doesn't work
You have an invalid ID
ID and NAME tokens must begin with a letter ([A-Za-z]) and may be followed by any number of letters, digits ([0-9]), hyphens ("-"), underscores ("_"), colons (":"), and periods ("."). (resource: What are valid values for the id attribute in HTML?)
you used some id that you already used as <meta>
name in your header (e.g. copyright, author... ) it looks weird but happened to me: if your 're using IE take a look at
(resource: http://www.phpied.com/getelementbyid-description-in-ie/)
you're targeting an element inside a frame or iframe. In this case if the iframe loads a page within the same domain of the parent you should target the contentdocument
before looking for the element
(resource: Calling a specific id inside a frame)
you're simply looking to an element when the node is not effectively loaded in the DOM, or maybe it's a simple misspelling
I doubt you used same ID twice or more: in that case document.getElementById
should return at least the first element
You can use:
$ jq 'keys' file.json
$ cat file.json:
{ "Archiver-Version" : "Plexus Archiver", "Build-Id" : "", "Build-Jdk" : "1.7.0_07", "Build-Number" : "", "Build-Tag" : "", "Built-By" : "cporter", "Created-By" : "Apache Maven", "Implementation-Title" : "northstar", "Implementation-Vendor-Id" : "com.test.testPack", "Implementation-Version" : "testBox", "Manifest-Version" : "1.0", "appname" : "testApp", "build-date" : "02-03-2014-13:41", "version" : "testBox" }
$ jq 'keys' file.json
[
"Archiver-Version",
"Build-Id",
"Build-Jdk",
"Build-Number",
"Build-Tag",
"Built-By",
"Created-By",
"Implementation-Title",
"Implementation-Vendor-Id",
"Implementation-Version",
"Manifest-Version",
"appname",
"build-date",
"version"
]
UPDATE: To create a BASH array using these keys:
Using BASH 4+:
mapfile -t arr < <(jq -r 'keys[]' ms.json)
On older BASH you can do:
arr=()
while IFS='' read -r line; do
arr+=("$line")
done < <(jq 'keys[]' ms.json)
Then print it:
printf "%s\n" ${arr[@]}
"Archiver-Version"
"Build-Id"
"Build-Jdk"
"Build-Number"
"Build-Tag"
"Built-By"
"Created-By"
"Implementation-Title"
"Implementation-Vendor-Id"
"Implementation-Version"
"Manifest-Version"
"appname"
"build-date"
"version"
Try to use
for today:
SELECT * FROM `tbl_name` where DATE(column_name) = CURDATE()
for selected date:
SELECT * FROM `tbl_name` where DATE(column_name) = DATE('2016-01-14')
Whilst not a description of the differences, below are a couple of things to think about when choosing the correct method.
All the example I've seen aren't reusable for different "yes/no" type questions. I was looking for something that would allow me to specify a callback so I could call for any situation.
The following is working well for me:
$.extend({ confirm: function (title, message, yesText, yesCallback) {
$("<div></div>").dialog( {
buttons: [{
text: yesText,
click: function() {
yesCallback();
$( this ).remove();
}
},
{
text: "Cancel",
click: function() {
$( this ).remove();
}
}
],
close: function (event, ui) { $(this).remove(); },
resizable: false,
title: title,
modal: true
}).text(message).parent().addClass("alert");
}
});
I then call it like this:
var deleteOk = function() {
uploadFile.del(fileid, function() {alert("Deleted")})
};
$.confirm(
"CONFIRM", //title
"Delete " + filename + "?", //message
"Delete", //button text
deleteOk //"yes" callback
);
Try mydatagrid.Items.Refresh()
When initializing an array, C allows you to fill it with values. So
char s[100] = "abcd";
is basically the same as
int s[3] = { 1, 2, 3 };
but it doesn't allow you to do the assignment since s
is an array and not a free pointer. The meaning of
s = "abcd"
is to assign the pointer value of abcd
to s
but you can't change s
since then nothing will be pointing to the array.
This can and does work if s
is a char*
- a pointer that can point to anything.
If you want to copy the string simple use strcpy
.
Function marr(arr1 As Variant, arr2 As Variant) As Variant
Dim item As Variant
For Each item In arr1
i = i + 1
Next item
For Each item In arr2
i = i + 1
Next item
ReDim MergeData(0 To i)
i = 1
For Each item In arr1
MergeData(i) = item
i = i + 1
Next item
For Each item In arr2
MergeData(i) = item
i = i + 1
Next item
marr = MergeData
End Function
$.fn.selectText = function () {
return $(this).each(function (index, el) {
if (document.selection) {
var range = document.body.createTextRange();
range.moveToElementText(el);
range.select();
} else if (window.getSelection) {
var range = document.createRange();
range.selectNode(el);
window.getSelection().addRange(range);
}
});
}
Above answer is not working in Chrome because addRange remove previous added range. I didnt find any solution for this beside fake selection with css.
blak3r / Rushyo's solution works fine for everything except Windows 8. Running AT
on Windows 8 results in:
The AT command has been deprecated. Please use schtasks.exe instead.
The request is not supported.
(see screenshot #1) and will return %errorLevel%
1
.
So, I went searching for other commands that require elevated permissions. rationallyparanoid.com had a list of a few, so I ran each command on the two opposite extremes of current Windows OSs (XP and 8) in the hopes of finding a command that would be denied access on both OSs when run with standard permissions.
Eventually, I did find one - NET SESSION
. A true, clean, universal solution that doesn't involve:
FOR
loopsAT
(Windows 8 incompatible) or WHOAMI
(Windows XP incompatible). Each of which have their own security, usability, and portability issues.
I've independently confirmed that this works on:
(see screenshot #2)
So, to use this solution, simply do something like this:
@echo off
goto check_Permissions
:check_Permissions
echo Administrative permissions required. Detecting permissions...
net session >nul 2>&1
if %errorLevel% == 0 (
echo Success: Administrative permissions confirmed.
) else (
echo Failure: Current permissions inadequate.
)
pause >nul
Available here, if you're lazy: https://dl.dropbox.com/u/27573003/Distribution/Binaries/check_Permissions.bat
NET SESSION
is a standard command used to "manage server computer connections. Used without parameters, [it] displays information about all sessions with the local computer."
So, here's the basic process of my given implementation:
@echo off
goto check_Permissions
:check_Permissions
code blocknet session >nul 2>&1
STDOUT
) stream to nul
STDERR
) to the same destination as numeric handle 1if %errorLevel% == 0
%errorLevel%
) is 0
then this means that no errors have occurred and, therefore, the immediate previous command ran successfullyelse
%errorLevel%

then this means that errors have occurred and, therefore, the immediate previous command ran unsuccessfully

You can create an extension function similar to java.util.Random.nextInt(int)
but one that takes an IntRange
instead of an Int
for its bound:
fun Random.nextInt(range: IntRange): Int {
return range.start + nextInt(range.last - range.start)
}
You can now use this with any Random
instance:
val random = Random()
println(random.nextInt(5..9)) // prints 5, 6, 7, 8, or 9
If you don't want to have to manage your own Random
instance then you can define a convenience method using, for example, ThreadLocalRandom.current()
:
fun rand(range: IntRange): Int {
return ThreadLocalRandom.current().nextInt(range)
}
Now you can get a random integer as you would in Ruby without having to first declare a Random
instance yourself:
rand(5..9) // returns 5, 6, 7, 8, or 9
Have a same problem. My solution is after you handle with parsing arguments using argparse or other way, remove arguments from sys.argv
sys.argv = sys.argv[:1]
If you need you can filter unittest arguments from main.parseArgs()
FQDN means the resolved name over DNS. It should be like "server-name.search-domain".
The warning you get just provides a notice that httpd can not find a FQDN, so it might not work right to handle a name-based virtual host. So make sure the expected FQDN is registered in your DNS server, or manually add the entry in /etc/hosts
which is prior to hitting DNS.

I've been looking for an answer for this question in SO and some other sites, but one gave an answer was very complex to me and some others answers simply doesn't work correctly, so after a lot code testing I solved this puzzle.
Note: I'm using Windows 8 and my taskbar isn't on auto-hide mode.
I discovered that setting the WindowState to Normal before performing any modifications will stop the error with the not covered taskbar.
I created this class that have two methods, the first enters in the "full screen mode" and the second leaves the "full screen mode". So you just need to create an object of this class and pass the Form you want to set full screen as an argument to the EnterFullScreenMode method or to the LeaveFullScreenMode method:
class FullScreen
{
public void EnterFullScreenMode(Form targetForm)
{
targetForm.WindowState = FormWindowState.Normal;
targetForm.FormBorderStyle = FormBorderStyle.None;
targetForm.WindowState = FormWindowState.Maximized;
}
public void LeaveFullScreenMode(Form targetForm)
{
targetForm.FormBorderStyle = System.Windows.Forms.FormBorderStyle.Sizable;
targetForm.WindowState = FormWindowState.Normal;
}
}
private void fullScreenToolStripMenuItem_Click(object sender, EventArgs e)
{
FullScreen fullScreen = new FullScreen();
if (fullScreenMode == FullScreenMode.No) // FullScreenMode is an enum
{
fullScreen.EnterFullScreenMode(this);
fullScreenMode = FullScreenMode.Yes;
}
else
{
fullScreen.LeaveFullScreenMode(this);
fullScreenMode = FullScreenMode.No;
}
}
I have placed this same answer on another question that I'm not sure if is a duplicate or not of this one. (Link to the other question: How do I make a WinForms app go Full Screen)
Math.sqrt returns a double so you'll have to cast it to int as well
distance = (int)Math.sqrt((x1-x2)*(x1-x2) + (y1-y2)*(y1-y2));
