Since this result is the first that Google returns for this error, I'll just add that if anyone looks for way do change java security settings without changing the global file java.security (for example you need to run some tests), you can just provide an overriding security file by JVM parameter -Djava.security.properties=your/file/path in which you can enable the necessary algorithms by overriding the disablements.
Because you need to enter in Java Preferences pane and flag only the JVM 7 in this way :
To easily and quickly open the Java Preferences pane in Mac OS X you can simply call spotlight with ?+SPACE and type System Preferences it will show up in the last row of the window.
I just modified hhafez's test to include StringBuilder. StringBuilder is 33 times faster than String.format using jdk 1.6.0_10 client on XP. Using the -server switch lowers the factor to 20.
public class StringTest {
public static void main( String[] args ) {
test();
test();
}
private static void test() {
int i = 0;
long prev_time = System.currentTimeMillis();
long time;
for ( i = 0; i < 1000000; i++ ) {
String s = "Blah" + i + "Blah";
}
time = System.currentTimeMillis() - prev_time;
System.out.println("Time after for loop " + time);
prev_time = System.currentTimeMillis();
for ( i = 0; i < 1000000; i++ ) {
String s = String.format("Blah %d Blah", i);
}
time = System.currentTimeMillis() - prev_time;
System.out.println("Time after for loop " + time);
prev_time = System.currentTimeMillis();
for ( i = 0; i < 1000000; i++ ) {
new StringBuilder("Blah").append(i).append("Blah");
}
time = System.currentTimeMillis() - prev_time;
System.out.println("Time after for loop " + time);
}
}
While this might sound drastic, I consider it to be relevant only in rare cases, because the absolute numbers are pretty low: 4 s for 1 million simple String.format calls is sort of ok - as long as I use them for logging or the like.
Update: As pointed out by sjbotha in the comments, the StringBuilder test is invalid, since it is missing a final .toString().
The correct speed-up factor from String.format(.) to StringBuilder is 23 on my machine (16 with the -server switch).
To be safe you don't break stuff (for example when these strings are changed in your code or further up), or crash you program (in case the returned string was literal for example like "hello I'm a literal string" and you start to edit it), make a copy of the returned string.
You could use strdup() for this, but read the small print. Or you can of course create your own version if it's not there on your platform.
If the current page was loaded by a POST request, you may want to use
window.location = window.location.pathname;
instead of
window.location.reload();
because window.location.reload() will prompt for confirmation if called on a page that was loaded by a POST request.
Logo is always a terrific starting point.
Brian Harvey's UCBLogo page has this short example:
Here is a short but complete program in Berkeley Logo:
to choices :menu [:sofar []] if emptyp :menu [print :sofar stop] foreach first :menu [(choices butfirst :menu sentence :sofar ?)] endAnd here's how you use it. You type
choices [[small medium large] [vanilla [ultra chocolate] lychee [rum raisin] ginger] [cone cup]]and Logo replies
small vanilla cone small vanilla cup small ultra chocolate cone small ultra chocolate cup small lychee cone small lychee cup small rum raisin cone small rum raisin cup small ginger cone small ginger cup medium vanilla cone medium vanilla cup medium ultra chocolate cone medium ultra chocolate cup medium lychee cone medium lychee cup medium rum raisin cone medium rum raisin cup medium ginger cone medium ginger cup large vanilla cone large vanilla cup large ultra chocolate cone large ultra chocolate cup large lychee cone large lychee cup large rum raisin cone large rum raisin cup large ginger cone large ginger cupThe program doesn't have anything about the size of the menu built in. You can use any number of categories, and any number of possibilities in each category. Let's see you do that in four lines of Java!
i'm using arrayadpter ,using this follwed code i'm able to get items
String value = (String)adapter.getItemAtPosition(position);
listView.setOnItemClickListener(new OnItemClickListener() {
@Override
public void onItemClick(AdapterView<?> parent, View view,
int position, long id) {
String string=adapter.getItem(position);
Log.d("**********", string);
}
});
For production environments you should use Forever.js
It's so util for start and stop node process, you can list apps running too.
Just install the necessary types for react and it should solve the error.
if you are using yarn:
yarn add @types/react @types/react-dom @types/react-router-dom -D
if you are using npm:
npm install @types/react @types/react-dom @types/react-router-dom --save-dev
I've always considered throwing checked exceptions in the constructor to be bad practice, or at least something that should be avoided.
The reason for this is that you cannot do this :
private SomeObject foo = new SomeObject();
Instead you must do this :
private SomeObject foo;
public MyObject() {
try {
foo = new SomeObject()
} Catch(PointlessCheckedException e) {
throw new RuntimeException("ahhg",e);
}
}
At the point when I'm constructing SomeObject I know what it's parameters are so why should I be expected to wrap it in a try catch? Ahh you say but if I'm constructing an object from dynamic parameters I don't know if they're valid or not. Well, you could... validate the parameters before passing them to the constructor. That would be good practice. And if all you're concerned about is whether the parameters are valid then you can use IllegalArgumentException.
So instead of throwing checked exceptions just do
public SomeObject(final String param) {
if (param==null) throw new NullPointerException("please stop");
if (param.length()==0) throw new IllegalArgumentException("no really, please stop");
}
Of course there are cases where it might just be reasonable to throw a checked exception
public SomeObject() {
if (todayIsWednesday) throw new YouKnowYouCannotDoThisOnAWednesday();
}
But how often is that likely?
Some simple cases can be handled by defining a default in the database schema but that doesn't handle a number of trickier cases including calculated values and keys of other models. For these cases I do this:
after_initialize :defaults
def defaults
unless persisted?
self.extras||={}
self.other_stuff||="This stuff"
self.assoc = [OtherModel.find_by_name('special')]
end
end
I've decided to use the after_initialize but I don't want it to be applied to objects that are found only those new or created. I think it is almost shocking that an after_new callback isn't provided for this obvious use case but I've made do by confirming whether the object is already persisted indicating that it isn't new.
Having seen Brad Murray's answer this is even cleaner if the condition is moved to callback request:
after_initialize :defaults, unless: :persisted?
# ":if => :new_record?" is equivalent in this context
def defaults
self.extras||={}
self.other_stuff||="This stuff"
self.assoc = [OtherModel.find_by_name('special')]
end
That's correct, initially the ResultSet's cursor is pointing to before the first row, if the first call to next() returns false then there was no data in the ResultSet.
If you use this method, you may have to call beforeFirst() immediately after to reset it, since it has positioned itself past the first row now.
It should be noted however, that Seifer's answer below is a more elegant solution to this question.
ShellEd
Solutions below how to install ShellEd don't work for me. A lot of error on dependencies. Found solution that works for me.
System:
Linux Lubuntu 12.04
IDE:
Eclipse Kepler
In Eclipse, go to Help > Install New Software
Click Add...
Add the following Location, http://download.eclipse.org/releases/kepler, and name it "Eclipse Kepler".
Click OK.
Select the newly-created Eclipse Kepler site.
Expand the Web, XML, Java EE and OSGi Enterprise Development section at the bottom. Select WST Server Adaptors.
Click Next, and install like usual.
Restart Eclipse
Then add ShellEd repo likewise as listed above: http://sourceforge.net/projects/shelled/files/shelled/update/
And install it.
Restart Eclipse.
Also worked in Eclipse Indigo as said here: http://docs.wraithmonster.com/install-shelled

The default value of error_reporting flag is E_ALL & ~E_NOTICE if not set in php.ini. But in some installation (particularly installations targeting development environments) has E_ALL | E_STRICT set as value of this flag (this is the recommended value during development). In some cases, specially when you'll want to run some open source projects, that was developed prior to PHP 5.3 era and not yet updated with best practices defined by PHP 5.3, in your development environment, you'll probably run into getting some messages like you are getting. The best way to cope up on this situation, is to set only E_ALL as the value of error_reporting flag, either in php.ini or in code (probably in a front-controller like index.php in web-root as follows:
if(defined('E_STRICT')){
error_reporting(E_ALL);
}

asarray(x) is like array(x, copy=False)
Use asarray(x) when you want to ensure that x will be an array before any other operations are done. If x is already an array then no copy would be done. It would not cause a redundant performance hit.
Here is an example of a function that ensure x is converted into an array first.
def mysum(x):
return np.asarray(x).sum()
If you just have included a layout file at the beginning of onCreate() inside setContentView and want to get this layout to add new elements programmatically try this:
ViewGroup linearLayout = (ViewGroup) findViewById(R.id.linearLayoutID);
then you can create a new Button for example and just add it:
Button bt = new Button(this);
bt.setText("A Button");
bt.setLayoutParams(new LayoutParams(LayoutParams.FILL_PARENT,
LayoutParams.WRAP_CONTENT));
linerLayout.addView(bt);
You need to use the public properties from Main, and not try to directly change the internal variables.
Bill's answer is very good, but you may want to do some things with the request like compression or user-agents. The following code shows how you can various types of compression to your requests.
URL url = new URL(urlStr);
HttpURLConnection conn = (HttpURLConnection) url.openConnection(); // Cast shouldn't fail
HttpURLConnection.setFollowRedirects(true);
// allow both GZip and Deflate (ZLib) encodings
conn.setRequestProperty("Accept-Encoding", "gzip, deflate");
String encoding = conn.getContentEncoding();
InputStream inStr = null;
// create the appropriate stream wrapper based on
// the encoding type
if (encoding != null && encoding.equalsIgnoreCase("gzip")) {
inStr = new GZIPInputStream(conn.getInputStream());
} else if (encoding != null && encoding.equalsIgnoreCase("deflate")) {
inStr = new InflaterInputStream(conn.getInputStream(),
new Inflater(true));
} else {
inStr = conn.getInputStream();
}
To also set the user-agent add the following code:
conn.setRequestProperty ( "User-agent", "my agent name");
If someone wants like this. I think this is the closest to the requirements asked for in question
Here is how I have implemented this one
Add accessory view for each text field for which you want the setup, using
func setAccessoryViewFor(textField : UITextField) {
let toolBar = UIToolbar()
toolBar.barStyle = .default
toolBar.isTranslucent = true
toolBar.sizeToFit()
// Adds the buttons
// Add previousButton
let prevButton = UIBarButtonItem(title: "<", style: .plain, target: self, action: #selector(previousPressed(sender:)))
prevButton.tag = textField.tag
if getPreviousResponderFor(tag: textField.tag) == nil {
prevButton.isEnabled = false
}
// Add nextButton
let nextButton = UIBarButtonItem(title: ">", style: .plain, target: self, action: #selector(nextPressed(sender:)))
nextButton.tag = textField.tag
if getNextResponderFor(tag: textField.tag) == nil {
nextButton.title = "Done"
}
let spaceButton = UIBarButtonItem(barButtonSystemItem: .flexibleSpace, target: nil, action: nil)
toolBar.setItems([prevButton,spaceButton,nextButton], animated: false)
toolBar.isUserInteractionEnabled = true
textField.inputAccessoryView = toolBar
}
Use following functions to handle taps
func nextPressed(sender : UIBarButtonItem) {
if let nextResponder = getNextResponderFor(tag: sender.tag) {
nextResponder.becomeFirstResponder()
} else {
self.view.endEditing(true)
}
}
func previousPressed(sender : UIBarButtonItem) {
if let previousResponder = getPreviousResponderFor(tag : sender.tag) {
previousResponder.becomeFirstResponder()
}
}
func getNextResponderFor(tag : Int) -> UITextField? {
return self.view.viewWithTag(tag + 1) as? UITextField
}
func getPreviousResponderFor(tag : Int) -> UITextField? {
return self.view.viewWithTag(tag - 1) as? UITextField
}
You will need to give the textFields tags in sequence in which you want the next/prev button to respond.

Want to put out there that there is not much to worry about if someone provides an answer as an extension method because an extension method is just a cool way to call an instance method. I understand that you want the answer without using an extension method. Regardless if the method is defined as static, instance or extension - the result is the same.
The code below uses the code from the accepted answer to define an extension method and an instance method and creates a unit test to show the output is the same.
public static class Extensions
{
public static void Each<T>(this IEnumerable<T> items, Action<T> action)
{
foreach (var item in items)
{
action(item);
}
}
}
[TestFixture]
public class ForEachTests
{
public void Each<T>(IEnumerable<T> items, Action<T> action)
{
foreach (var item in items)
{
action(item);
}
}
private string _extensionOutput;
private void SaveExtensionOutput(string value)
{
_extensionOutput += value;
}
private string _instanceOutput;
private void SaveInstanceOutput(string value)
{
_instanceOutput += value;
}
[Test]
public void Test1()
{
string[] teams = new string[] {"cowboys", "falcons", "browns", "chargers", "rams", "seahawks", "lions", "heat", "blackhawks", "penguins", "pirates"};
Each(teams, SaveInstanceOutput);
teams.Each(SaveExtensionOutput);
Assert.AreEqual(_extensionOutput, _instanceOutput);
}
}
Quite literally, the only thing you need to do to convert an extension method to an instance method is remove the static modifier and the first parameter of the method.
This method
public static void Each<T>(this IEnumerable<T> items, Action<T> action)
{
foreach (var item in items)
{
action(item);
}
}
becomes
public void Each<T>(Action<T> action)
{
foreach (var item in items)
{
action(item);
}
}
This works better for me:

You can do smth like this for 1D arrays. Here we use int*& because we want our pointer to be changeable.
#include<algorithm> // for copy
void resize(int*& a, size_t& n)
{
size_t new_n = 2 * n;
int* new_a = new int[new_n];
copy(a, a + n, new_a);
delete[] a;
a = new_a;
n = new_n;
}
For 2D arrays:
#include<algorithm> // for copy
void resize(int**& a, size_t& n)
{
size_t new_n = 2 * n, i = 0;
int** new_a = new int* [new_n];
for (i = 0; i != new_n; ++i)
new_a[i] = new int[100];
for (i = 0; i != n; ++i)
{
copy(a[i], a[i] + 100, new_a[i]);
delete[] a[i];
}
delete[] a;
a = new_a;
n = new_n;
}
Invoking of 1D array:
void myfn(int*& a, size_t& n)
{
// do smth
resize(a, n);
}
Invoking of 2D array:
void myfn(int**& a, size_t& n)
{
// do smth
resize(a, n);
}
git push -f is a bit destructive because it resets any remote changes that had been made by anyone else on the team. A safer option is {git push --force-with-lease}.
What {--force-with-lease} does is refuse to update a branch unless it is the state that we expect; i.e. nobody has updated the branch upstream. In practice this works by checking that the upstream ref is what we expect, because refs are hashes, and implicitly encode the chain of parents into their value. You can tell {--force-with-lease} exactly what to check for, but by default will check the current remote ref. What this means in practice is that when Alice updates her branch and pushes it up to the remote repository, the ref pointing head of the branch will be updated. Now, unless Bob does a pull from the remote, his local reference to the remote will be out of date. When he goes to push using {--force-with-lease}, git will check the local ref against the new remote and refuse to force the push. {--force-with-lease} effectively only allows you to force-push if no-one else has pushed changes up to the remote in the interim. It's {--force} with the seatbelt on.
You can compare hashes directly for equality:
hash1 = {'a' => 1, 'b' => 2}
hash2 = {'a' => 1, 'b' => 2}
hash3 = {'a' => 1, 'b' => 2, 'c' => 3}
hash1 == hash2 # => true
hash1 == hash3 # => false
hash1.to_a == hash2.to_a # => true
hash1.to_a == hash3.to_a # => false
You can convert the hashes to arrays, then get their difference:
hash3.to_a - hash1.to_a # => [["c", 3]]
if (hash3.size > hash1.size)
difference = hash3.to_a - hash1.to_a
else
difference = hash1.to_a - hash3.to_a
end
Hash[*difference.flatten] # => {"c"=>3}
Simplifying further:
Assigning difference via a ternary structure:
difference = (hash3.size > hash1.size) \
? hash3.to_a - hash1.to_a \
: hash1.to_a - hash3.to_a
=> [["c", 3]]
Hash[*difference.flatten]
=> {"c"=>3}
Doing it all in one operation and getting rid of the difference variable:
Hash[*(
(hash3.size > hash1.size) \
? hash3.to_a - hash1.to_a \
: hash1.to_a - hash3.to_a
).flatten]
=> {"c"=>3}
You can use the following function to find the biggest [number] in any string.
It returns the value of the biggest [number] as an Integer.
var biggestNumber = function(str) {
var pattern = /\[([0-9]+)\]/g, match, biggest = 0;
while ((match = pattern.exec(str)) !== null) {
if (match.index === pattern.lastIndex) {
pattern.lastIndex++;
}
match[1] = parseInt(match[1]);
if(biggest < match[1]) {
biggest = match[1];
}
}
return biggest;
}
The following demo calculates the biggest number in your textarea every time you click the button.
It allows you to play around with the textarea and re-test the function with a different text.
var biggestNumber = function(str) {_x000D_
var pattern = /\[([0-9]+)\]/g, match, biggest = 0;_x000D_
_x000D_
while ((match = pattern.exec(str)) !== null) {_x000D_
if (match.index === pattern.lastIndex) {_x000D_
pattern.lastIndex++;_x000D_
}_x000D_
match[1] = parseInt(match[1]);_x000D_
if(biggest < match[1]) {_x000D_
biggest = match[1];_x000D_
}_x000D_
}_x000D_
return biggest;_x000D_
}_x000D_

I encountered the same issue on Mac OSX, using a ZSH shell: in this case there is no -t option for mv, so I had to find another solution.
However the following command succeeded:
find .* * -maxdepth 0 -not -path '.git' -not -path '.backup' -exec mv '{}' .backup \;
The secret was to quote the braces. No need for the braces to be at the end of the exec command.
I tested under Ubuntu 14.04 (with BASH and ZSH shells), it works the same.
However, when using the + sign, it seems indeed that it has to be at the end of the exec command.
static means "associated with the class"; without it, the variable is associated with each instance of the class. If it's static, that means you'll have only one in memory; if not, you'll have one for each instance you create. static means the variable will remain in memory for as long as the class is loaded; without it, the variable can be gc'd when its instance is.
You may write your "main.py" like this:

somevar=""
def do_something():
pass #blahblah
if __name__=="__main__":
do_something()
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.
Working from VaLo's answer:
cd %directory to browser%
%browser's name to main executable (firefox, chrome, opera, etc.)% https://www.google.com
start https://www.google.com doesn't seem to work (at least in my environment)
Try this instead:
=SUM(IF(MONTH($A$2:$A$6)=1,$B$2:$B$6,0))
It's an array formula, so you will need to enter it with the Control-Shift-Enter key combination.
Here's how the formula works.
{1, 1, 1, 2, 2}.{1, 1, 1, 2, 2}= 1 produces the array {TRUE, TRUE, TRUE, FALSE, FALSE}, which comprises the condition for the IF statement.{430, 96, 400.. for the values of the sum ranges where the month value equals 1 and ..0,0} where the month value does not equal 1.{430, 96, 400, 0, 0} is then summed to get the answer you are looking for.This is essentially equivalent to what the SUMIF and SUMIFs functions do. However, neither of those functions support the kind of calculation you tried to include in the conditional.
It's also possible to drop the IF completely. Since TRUE and FALSE can also be treated as 1 and 0, this formula--=SUM((MONTH($A$2:$A$6)=1)*$B$2:$B$6)--also works.
Heads up: This does not work in Google Spreadsheets
FragmentTabHost is also an option.
This code is from Android developer's site:
/**

private FragmentTabHost mTabHost;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.fragment_tabs);
mTabHost = (FragmentTabHost)findViewById(android.R.id.tabhost);
mTabHost.setup(this, getSupportFragmentManager(), R.id.realtabcontent);
mTabHost.addTab(mTabHost.newTabSpec("simple").setIndicator("Simple"),
FragmentStackSupport.CountingFragment.class, null);
mTabHost.addTab(mTabHost.newTabSpec("contacts").setIndicator("Contacts"),
LoaderCursorSupport.CursorLoaderListFragment.class, null);
mTabHost.addTab(mTabHost.newTabSpec("custom").setIndicator("Custom"),
LoaderCustomSupport.AppListFragment.class, null);
mTabHost.addTab(mTabHost.newTabSpec("throttle").setIndicator("Throttle"),
LoaderThrottleSupport.ThrottledLoaderListFragment.class, null);
}
}

You can use OPTION(MAXRECURSION n) to control recursion depth.
Actually, rebase saves your starting point to ORIG_HEAD so this is usually as simple as:
git reset --hard ORIG_HEAD
However, the reset, rebase and merge all save your original HEAD pointer into ORIG_HEAD so, if you've done any of those commands since the rebase you're trying to undo then you'll have to use the reflog.
your server should enable the cross origin requests, not the client. To do this, you can check this nice page with implementations and configurations for multiple platforms
var sibling = node.nextSibling;
This will return the sibling immediately after it, or null no more siblings are available. Likewise, you can use previousSibling.
[Edit] On second thought, this will not give the next div tag, but the whitespace after the node. Better seems to be
var sibling = node.nextElementSibling;
There also exists a previousElementSibling.
It's possible using the \A escape sequence in the psuedo-element generated content. Read more in the CSS2 spec.

p.s. Another treatment to be
:before { content: ' '; display: block; }
Below is the code for pass unique notification id:
//"CommonUtilities.getValudeFromOreference" is the method created by me to get value from savedPreferences.
String notificationId = CommonUtilities.getValueFromPreference(context, Global.NOTIFICATION_ID, "0");
int notificationIdinInt = Integer.parseInt(notificationId);
notificationManager.notify(notificationIdinInt, notification);
// will increment notification id for uniqueness
notificationIdinInt = notificationIdinInt + 1;
CommonUtilities.saveValueToPreference(context, Global.NOTIFICATION_ID, notificationIdinInt + "");
//Above "CommonUtilities.saveValueToPreference" is the method created by me to save new value in savePreferences.
Reset notificationId in savedPreferences at specific range like I have did it at 1000. So it will not create any issues in future.
Let me know if you need more detail information or any query. :)
I had the same problem using VS2010. I know this isn't really an answer. I just thought it might help someone. I resolved it by using the fully qualified name for DBContext.
Instead of
public class MachineDbContext : DbContext
I used
public class MachineDbContext : System.Data.Entity.DbContext
and rebuilt the project. Suddenly VS was happy, and I was even able to remove the fully qualified name, and just use DBContext.
//It is working
#include<iostream>
using namespace std;
void main()
{
int a[5];
int temp=0;
cout<<"Enter Values"<<endl;
for(int i=0;i<5;i++)
{
cin>>a[i];
}
for(int i=0;i<5;i++)
{
for(int j=0;j<5;j++)
{
if(a[i]>a[j])
{
temp=a[i];
a[i]=a[j];
a[j]=temp;
}
}
}
cout<<"Asending Series"<<endl;
for(int i=0;i<5;i++)
{
cout<<endl;
cout<<a[i]<<endl;
}
for(int i=0;i<5;i++)
{
for(int j=0;j<5;j++)
{
if(a[i]<a[j])
{
temp=a[i];
a[i]=a[j];
a[j]=temp;
}
}
}
cout<<"Desnding Series"<<endl;
for(int i=0;i<5;i++)
{
cout<<endl;
cout<<a[i]<<endl;
}
}
I was also looking for a way to do it and figured it out like this using forms and the formaction attribute:
<input type="submit" name="del_something" formaction="<addresstothispage>" value="delete" />
<?php if(isset($_POST['del_something'])) print '<div>Are you sure? <input type="submit" name="del_confirm" value="yes!" formaction="action.php" />
<input type="submit" name="del_no" value="no!" formaction="<addresstothispage>" />';?>
action.php would check for isset($_POST['del_confirm']) and call the corresponding php script (for database actions or whatever). Voilà, no javascript needed. Using the formaction attribute, the delete button can be part of any form and still call a different form action (such as refer back to the same page, but with the button set).
If the button was pressed, the confirm buttons will show.
You have to define your TASK_CAT column first and then set foreign key on it.
private static final String TASK_TABLE_CREATE = "create table "
+ TASK_TABLE + " ("
+ TASK_ID + " integer primary key autoincrement, "
+ TASK_TITLE + " text not null, "
+ TASK_NOTES + " text not null, "
+ TASK_DATE_TIME + " text not null,"
+ TASK_CAT + " integer,"
+ " FOREIGN KEY ("+TASK_CAT+") REFERENCES "+CAT_TABLE+"("+CAT_ID+"));";
More information you can find on sqlite foreign keys doc.
As a complement to the answers given above; do not forget about Form MinimumSize Property, in case you require to create smaller Forms.
Example Bellow:
private void SetDefaultWindowSize()
{
int sizeW, sizeH;
sizeW = 180;
sizeH = 100;
var size = new Size(sizeW, sizeH);
Size = size;
MinimumSize = size;
}
private void SetNewSize()
{
Size = new Size(Width, 10);
}
I was getting the same error message but had a different issue. Posting for others that are stuck on same.
I ported the get, post, put, delete functions to new router file while refactoring, and forgot to edit the paths. Example:
Incorrect:
//server.js
app.use('/blog-posts', blogPostsRouter);
//routers/blogPostsRouter.js
router.get('/blog-posts', (req, res) => {
res.json(BlogPosts.get());
});
Correct:
//server.js
app.use('/blog-posts', blogPostsRouter);
//routers/blogPostsRouter.js
router.get('/', (req, res) => {
res.json(BlogPosts.get());
});
Took a while to spot, as the error had me checking syntax where I might have been wrapping an argument in an object or where I missed the module.exports = router;
You shall proceed with ent.delete(0,"end") instead of using 'END', use 'end' inside quotation.
secret = randrange(1,100)
print(secret)
def res(real, secret):
if secret==eval(real):
showinfo(message='that is right!')
real.delete(0, END)
def guess():
ge = Tk()
ge.title('guessing game')
Label(ge, text="what is your guess:").pack(side=TOP)
ent = Entry(ge)
ent.pack(side=TOP)
btn=Button(ge, text="Enter", command=lambda: res(ent.get(),secret))
btn.pack(side=LEFT)
ge.mainloop()
This shall solve your problem
Check you are including all the source files within your solution that you are referencing.
If you are not including the source file (and thus the implementation) for the class Field in your project it won't be built and you will be unable to link during compilation.
Alternatively, perhaps you are using a static or dynamic library and have forgotten to tell the linker about the .libs?
I did this:
import re
def requirements(filename):
with open(filename) as f:
ll = f.read().splitlines()
d = {}
for l in ll:
k, v = re.split(r'==|>=', l)
d[k] = v
return d
def packageInfo():
try:
from pip._internal.operations import freeze
except ImportError:
from pip.operations import freeze
d = {}
for kv in freeze.freeze():
k, v = re.split(r'==|>=', kv)
d[k] = v
return d
req = getpackver('requirements.txt')
pkginfo = packageInfo()
for k, v in req.items():
print(f'{k:<16}: {v:<6} -> {pkginfo[k]}')
For a Windows console app, you want to use SetConsoleCtrlHandler to handle CTRL+C and CTRL+BREAK.
See here for an example.
As of Python 3.2 2.7, there is now argparse for processing command line arguments.
I'd express the format as:
"1-3 dot-separated components, each numeric except that the last one may be *"
As a regexp, that's:
^(\d+\.)?(\d+\.)?(\*|\d+)$
[Edit to add: this solution is a concise way to validate, but it has been pointed out that extracting the values requires extra work. It's a matter of taste whether to deal with this by complicating the regexp, or by processing the matched groups.
In my solution, the groups capture the "." characters. This can be dealt with using non-capturing groups as in ajborley's answer.
Also, the rightmost group will capture the last component, even if there are fewer than three components, and so for example a two-component input results in the first and last groups capturing and the middle one undefined. I think this can be dealt with by non-greedy groups where supported.
Perl code to deal with both issues after the regexp could be something like this:
@version = ();
@groups = ($1, $2, $3);
foreach (@groups) {
next if !defined;
s/\.//;
push @version, $_;
}
($major, $minor, $mod) = (@version, "*", "*");
Which isn't really any shorter than splitting on "."

A simpler way to do this is to add a post-receive script which runs the chmod command after every push to the 'hub' repo on the server. Add the following line to hooks/post-receive inside your git folder on the server:
chmod -Rf u+w /path/to/git/repo/objects
best and simple
requestWindowFeature(Window.FEATURE_NO_TITLE);
getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
WindowManager.LayoutParams.FLAG_FULLSCREEN);
Perhaps not the best options but just another way is to read the Windows Registry in the host machine, on elevated PowerShell prompt you can do something like this:
#Get SQL instance's Port number using Windows Registry:
$instName = (Get-ItemProperty 'HKLM:\SOFTWARE\Microsoft\Microsoft SQL Server').InstalledInstances[0]
$tcpPort = (Get-ItemProperty "HKLM:\SOFTWARE\Microsoft\Microsoft SQL Server\$instName\MSSQLServer\SuperSocketNetLib\Tcp").TcpPort
Write-Host The SQL Instance: `"$instName`" is listening on `"$tcpPort`" "TcpPort."
Ensure to run this PowerShell script in the Host Server (that hosts your SQL instance / SQL Server installation), which means you have to first RDP into the SQL Server/Box/VM, then run this code.

The object you're saving should have a correct Id after propagating changes into database.
This is an issue relating JRE.In my case (eclipse Luna with Maven plugin, JDK 7) I solved this by making following change in pom.xml and then Maven Update Project.
from:
<configuration>
<source>1.8</source>
<target>1.8</target>
</configuration>
to:
<configuration>
<source>1.7</source>
<target>1.7</target>

Removing some unnecessary SQL and then COUNT(*) will be faster than SQL_CALC_FOUND_ROWS. Example:
SELECT Person.Id, Person.Name, Job.Description, Card.Number
FROM Person
JOIN Job ON Job.Id = Person.Job_Id
LEFT JOIN Card ON Card.Person_Id = Person.Id
WHERE Job.Name = 'WEB Developer'
ORDER BY Person.Name
Then count without unnecessary part:
SELECT COUNT(*)
FROM Person
JOIN Job ON Job.Id = Person.Job_Id
WHERE Job.Name = 'WEB Developer'
Before you start, go to the directory "phpMyAdmin" preferably the one in your localhost, clear all of your cookies, and have your sql running by entering:
sudo /usr/local/mysql/support-files/mysql.server start
To fix the error , you will have to run the following commands in your terminal:
export PATH=$PATH:/usr/local/mysql/bin/
then:
mysql -u root
after which, you'll need to change your permissions inside the mySQL shell:
UPDATE user SET Password=PASSWORD('YOURNEWPASSWORD') WHERE User='root'; FLUSH PRIVILEGES; exit;
Refresh your phpMyAdmin window, re-enter the "root" username (or whichever is applicable), and your password and you should be good to go. Check http://machiine.com/2013/how-to-setup-phpmyadmin-on-a-mac-with-osx-10-8-mamp-part-3/ if you are willing to set up from scratch.
ind_list = [1, 3]
df.ix[ind_list]
should do the trick! When I index with data frames I always use the .ix() method. Its so much easier and more flexible...
UPDATE
This is no longer the accepted method for indexing. The ix method is deprecated. Use .iloc for integer based indexing and .loc for label based indexing.
try this
Object.keys(data).length
If IE < 9, you can loop through the object yourself with a for loop
var len = 0;
var i;
for (i in data) {
if (data.hasOwnProperty(i)) {
len++;
}
}
No, there is no difference. But I prefer using int[] array as it is more readable.
Setting the style.zIndex property has no effect on non-positioned elements, that is, the element must be either absolutely positioned, relatively positioned, or fixed.
So I would try:
$(this).parent().css('position', 'relative');
$(this).parent().css('z-index', 3000);
It's all in the tutorial how to do that:
ContentValues args = new ContentValues();
args.put(columnName, newValue);
db.update(DATABASE_TABLE, args, KEY_ROWID + "=" + rowId, null);
Use ContentValues to set the updated columns and than the update() method in which you have to specifiy, the table and a criteria to only update the rows you want to update.
Getting the Text of ComboBox when the item is changed
self.ui.comboBox.activated.connect(self.pass_Net_Adap)
def pass_Net_Adap(self):
print str(self.ui.comboBox.currentText())
Before pasting into the terminal, try :set paste and then :set nopaste after you're done. This will turn off the auto-indent, line-wrap and other features that are messing up your paste.
edit: Also, I should point out that a much better result than = indenting can usually be obtained by using an external program. For example, I run :%!perltidy all the time. astyle, cindent, etc. can also be used. And, of course, you can map those to a key stroke, and map different ones to the same keystroke depending on file type.
As an addition to the Gerold Broser's answer, here an example of mocking a static method with arguments:
class Buddy {
static String addHello(String name) {
return "Hello " + name;
}
}
...
@Test
void testMockStaticMethods() {
assertThat(Buddy.addHello("John")).isEqualTo("Hello John");
try (MockedStatic<Buddy> theMock = Mockito.mockStatic(Buddy.class)) {
theMock.when(() -> Buddy.addHello("John")).thenReturn("Guten Tag John");
assertThat(Buddy.addHello("John")).isEqualTo("Guten Tag John");
}
assertThat(Buddy.addHello("John")).isEqualTo("Hello John");
}
useEffect can hook on a certain prop or state. so, the thing you need to do to avoid infinite loop hook is binding some variable or state to effect
For Example:
useEffect(myeffectCallback, [])
above effect will fire only once the component has rendered. this is similar to componentDidMount lifecycle
const [something, setSomething] = withState(0)
const [myState, setMyState] = withState(0)
useEffect(() => {
setSomething(0)
}, myState)
above effect will fire only my state has changed this is similar to componentDidUpdate except not every changing state will fire it.

Using Accept header is really easy to get the format json or xml from the REST service.
This is my Controller, take a look produces section.
@RequestMapping(value = "properties", produces = {MediaType.APPLICATION_JSON_VALUE, MediaType.APPLICATION_XML_VALUE}, method = RequestMethod.GET)
public UIProperty getProperties() {
return uiProperty;
}
In order to consume the REST service we can use the code below where header can be MediaType.APPLICATION_JSON_VALUE or MediaType.APPLICATION_XML_VALUE
HttpHeaders headers = new HttpHeaders();
headers.add("Accept", header);
HttpEntity entity = new HttpEntity(headers);
RestTemplate restTemplate = new RestTemplate();
ResponseEntity<String> response = restTemplate.exchange("http://localhost:8080/properties", HttpMethod.GET, entity,String.class);
return response.getBody();
Edit 01:
In order to work with application/xml, add this dependency
<dependency>
<groupId>com.fasterxml.jackson.dataformat</groupId>
<artifactId>jackson-dataformat-xml</artifactId>
</dependency>
To change only the second column of a table use the following:
General Case:
table td + td{ /* this will go to the 2nd column of a table directly */
background:red
}
Your case:
.countTable table table td + td{
background: red
}
Note: this works for all browsers (Modern and old ones) that's why I added my answer to an old question
I tried several solutions, nothing seemed to work. Setting my system JDK to match Android Studio's solved the problem.
Ensure your system java
java -version
Is the same as Androids
File > Project Structure > JDK Location
Best guess is you are on windows and your line ending settings are set for windows. See this topic: How to change line-ending settings
or use:
tr '\r\n' ' '
Actually all of the solutions were pretty complex, and I found a really simple solution (I'm not sure if it is available for all sdk versions). It will open the pdf document in a preview window where the user is able to view and save/share the document:
webView.setDownloadListener(DownloadListener { url, userAgent, contentDisposition, mimetype, contentLength ->
val i = Intent(Intent.ACTION_QUICK_VIEW)
i.data = Uri.parse(url)
if (i.resolveActivity(getPackageManager()) != null) {
startActivity(i)
} else {
val i2 = Intent(Intent.ACTION_VIEW)
i2.data = Uri.parse(url)
startActivity(i2)
}
})

It is not possible to export an Android library as a jar file. It is possible, however, to export it as aar file. Aar files being the new binary format for Android libraries. There's info about them in Google I/O, the New Build System video.
First, build the library in Android Studio or from command line issuing gradle build from your library's root directory.
This will result in <yourlibroot>/libs/build/yourlib.aar file.
This aar file is a binary representation of your library and can be added to your project instead of the library as a dependency project.
To add aar file as a dependency you have to publish it to the maven central or to your local maven repository, and then refer the aar file in your project's gradle.build file.
However, this step is a bit convoluted. I've found a good explanation how to do so here:
http://www.flexlabs.org/2013/06/using-local-aar-android-library-packages-in-gradle-builds
You can do this using Input.setSelectionRange, part of the Range API for interacting with text selections and the text cursor:
var searchInput = $('#Search');
// Multiply by 2 to ensure the cursor always ends up at the end;
// Opera sometimes sees a carriage return as 2 characters.
var strLength = searchInput.val().length * 2;
searchInput.focus();
searchInput[0].setSelectionRange(strLength, strLength);
Demo: Fiddle
public V[] getV(DataTable dtCloned)
{
V[] objV = new V[dtCloned.Rows.Count];
MyClasses mc = new MyClasses();
int i = 0;
int intError = 0;
foreach (DataRow dr in dtCloned.Rows)
{
try
{
V vs = new V();
vs.R = int.Parse(mc.ReplaceChar(dr["r"].ToString()).Trim());
vs.S = Int64.Parse(mc.ReplaceChar(dr["s"].ToString()).Trim());
objV[i] = vs;
i++;
}
catch (Exception ex)
{
//
DataRow row = dtError.NewRow();
row["r"] = dr["r"].ToString();
row["s"] = dr["s"].ToString();
dtError.Rows.Add(row);
intError++;
}
}
return vs;
}
The documentation has the complete answer. Anyway this is how it is done:
<input type="text" ng-model="filterValue">
<li ng-repeat="i in data | filter:{age:filterValue}:true"> {{i | json }}</li>
will filter only age in data array and true is for exact match.
For deep filtering,
<li ng-repeat="i in data | filter:{$:filterValue}:true"> {{i}}</li>
The $ is a special property for deep filter and the true is for exact match like above.
The href value inside the base tag will become your reference point for all your relative paths and thus override your current directory path value otherwise - the '~' is the root of your site
<head>
<base href="~/" />
</head>
Sorry to jump on this question late in the game but I have an answer for irregular (non-rectangular) shapes. I solved it using SVGs to generate masks of where I want to have the event attached.
The idea is to attach events to inlined SVGs, super cheap and even user friendly because there are plenty of programs for generating SVGs. The SVG can have a layer of the image as a background.

Mysql documentation says : CREATE SCHEMA is a synonym for CREATE DATABASE as of MySQL 5.0.2.
this all goes back to an ANSI standard for SQL in the mid-80s.
That standard had a "CREATE SCHEMA" command, and it served to introduce multiple name spaces for table and view names. All tables and views were created within a "schema". I do not know whether that version defined some cross-schema access to tables and views, but I assume it did. AFAIR, no product (at least back then) really implemented it, that whole concept was more theory than practice.
OTOH, ISTR this version of the standard did not have the concept of a "user" or a "CREATE USER" command, so there were products that used the concept of a "user" (who then had his own name space for tables and views) to implement their equivalent of "schema".
This is an area where systems differ.
As far as administration is concerned, this should not matter too much, because here you have differences anyway.
As far as you look at application code, you "only" have to care about cases where one application accesses tables from multiple name spaces. AFAIK, all systems support a syntax ".", and for this it should not matter whether the name space is that of a user, a "schema", or a "database".
ClassPath is affected depending on what you provide. There are a couple of ways to set something on the classpath:
spark.driver.extraClassPath or it's alias --driver-class-path to set extra classpaths on the node running the driver.spark.executor.extraClassPath to set extra class path on the Worker nodes.If you want a certain JAR to be effected on both the Master and the Worker, you have to specify these separately in BOTH flags.
Following the same rules as the JVM:
:
--conf "spark.driver.extraClassPath=/opt/prog/hadoop-aws-2.7.1.jar:/opt/prog/aws-java-sdk-1.10.50.jar";
--conf "spark.driver.extraClassPath=/opt/prog/hadoop-aws-2.7.1.jar;/opt/prog/aws-java-sdk-1.10.50.jar"This depends on the mode which you're running your job under:
Client mode - Spark fires up a Netty HTTP server which distributes the files on start up for each of the worker nodes. You can see that when you start your Spark job:
16/05/08 17:29:12 INFO HttpFileServer: HTTP File server directory is /tmp/spark-48911afa-db63-4ffc-a298-015e8b96bc55/httpd-84ae312b-5863-4f4c-a1ea-537bfca2bc2b
16/05/08 17:29:12 INFO HttpServer: Starting HTTP Server
16/05/08 17:29:12 INFO Utils: Successfully started service 'HTTP file server' on port 58922.
16/05/08 17:29:12 INFO SparkContext: Added JAR /opt/foo.jar at http://***:58922/jars/com.mycode.jar with timestamp 1462728552732
16/05/08 17:29:12 INFO SparkContext: Added JAR /opt/aws-java-sdk-1.10.50.jar at http://***:58922/jars/aws-java-sdk-1.10.50.jar with timestamp 1462728552767
Cluster mode - In cluster mode spark selected a leader Worker node to execute the Driver process on. This means the job isn't running directly from the Master node. Here, Spark will not set an HTTP server. You have to manually make your JARS available to all the worker node via HDFS/S3/Other sources which are available to all nodes.
In "Submitting Applications", the Spark documentation does a good job of explaining the accepted prefixes for files:
When using spark-submit, the application jar along with any jars included with the --jars option will be automatically transferred to the cluster. Spark uses the following URL scheme to allow different strategies for disseminating jars:
- file: - Absolute paths and file:/ URIs are served by the driver’s HTTP file server, and every executor pulls the file from the driver HTTP server.
- hdfs:, http:, https:, ftp: - these pull down files and JARs from the URI as expected
- local: - a URI starting with local:/ is expected to exist as a local file on each worker node. This means that no network IO will be incurred, and works well for large files/JARs that are pushed to each worker, or shared via NFS, GlusterFS, etc.
Note that JARs and files are copied to the working directory for each SparkContext on the executor nodes.
As noted, JARs are copied to the working directory for each Worker node. Where exactly is that? It is usually under /var/run/spark/work, you'll see them like this:
drwxr-xr-x 3 spark spark 4096 May 15 06:16 app-20160515061614-0027
drwxr-xr-x 3 spark spark 4096 May 15 07:04 app-20160515070442-0028
drwxr-xr-x 3 spark spark 4096 May 15 07:18 app-20160515071819-0029
drwxr-xr-x 3 spark spark 4096 May 15 07:38 app-20160515073852-0030

drwxr-xr-x 3 spark spark 4096 May 18 17:20 app-20160518172045-0033
And when you look inside, you'll see all the JARs you deployed along:
[*@*]$ cd /var/run/spark/work/app-20160508173423-0014/1/
[*@*]$ ll

The most important thing to understand is priority. If you pass any property via code, it will take precedence over any option you specify via spark-submit. This is mentioned in the Spark documentation:
Any values specified as flags or in the properties file will be passed on to the application and merged with those specified through SparkConf. Properties set directly on the SparkConf take highest precedence, then flags passed to spark-submit or spark-shell, then options in the spark-defaults.conf file
So make sure you set those values in the proper places, so you won't be surprised when one takes priority over the other.
Lets analyze each option in question:
--jars vs SparkContext.addJar: These are identical, only one is set through spark submit and one via code. Choose the one which suites you better. One important thing to note is that using either of these options does not add the JAR to your driver/executor classpath, you'll need to explicitly add them using the extraClassPath config on both.SparkContext.addJar vs SparkContext.addFile: Use the former when you have a dependency that needs to be used with your code. Use the latter when you simply want to pass an arbitrary file around to your worker nodes, which isn't a run-time dependency in your code.--conf spark.driver.extraClassPath=... or --driver-class-path: These are aliases, doesn't matter which one you choose--conf spark.driver.extraLibraryPath=..., or --driver-library-path ... Same as above, aliases.--conf spark.executor.extraClassPath=...: Use this when you have a dependency which can't be included in an uber JAR (for example, because there are compile time conflicts between library versions) and which you need to load at runtime.--conf spark.executor.extraLibraryPath=... This is passed as the java.library.path option for the JVM. Use this when you need a library path visible to the JVM.Would it be safe to assume that for simplicity, I can add additional application jar files using the 3 main options at the same time:
You can safely assume this only for Client mode, not Cluster mode. As I've previously said. Also, the example you gave has some redundant arguments. For example, passing JARs to --driver-library-path is useless, you need to pass them to extraClassPath if you want them to be on your classpath. Ultimately, what you want to do when you deploy external JARs on both the driver and the worker is:
spark-submit --jars additional1.jar,additional2.jar \
--driver-class-path additional1.jar:additional2.jar \
--conf spark.executor.extraClassPath=additional1.jar:additional2.jar \
--class MyClass main-application.jar
As @Ming mentioned:
pip install -r file.txt
Here's a simple line to force update all dependencies:
while read -r package; do pip install --upgrade --force-reinstall $package;done < pipfreeze.txt
TCP is like this.
Imagine you have a pen-pal on Mars (we communicated with written letters back in the good ol' days before the internet).
You need to send your pen pal the seven habits of highly effective people. So you decide to send it in seven separate letters:
etc.
etc..Letter 7 - Sharpen the Saw
You want to make sure that your pen pal receives all your letters - in order and that they arrive perfectly. If your pen pay receives letter 7 before letter 1 - that's no good. if your pen pal receives all letters except letter 3 - that also is no good.
Here's how we ensure that our requirements are met:
This answer is widely oriented around Git Flow. The tables have been generated with the nice ASCII Table Generator, and the history trees with this wonderful command (aliased as git lg):
git log --graph --abbrev-commit --decorate --date=format:'%Y-%m-%d %H:%M:%S' --format=format:'%C(bold blue)%h%C(reset) - %C(bold cyan)%ad%C(reset) %C(bold green)(%ar)%C(reset)%C(bold yellow)%d%C(reset)%n'' %C(white)%s%C(reset) %C(dim white)- %an%C(reset)'

git merge vs git rebaseFirst point: always merge features into develop, never rebase develop from features. This is a consequence of the Golden Rule of Rebasing:
The golden rule of
git rebaseis to never use it on public branches.
Never rebase anything you've pushed somewhere.
I would personally add: unless it's a feature branch AND you and your team are aware of the consequences.
So the question of git merge vs git rebase applies almost only to the feature branches (in the following examples, --no-ff has always been used when merging). Note that since I'm not sure there's one better solution (a debate exists), I'll only provide how both commands behave. In my case, I prefer using git rebase as it produces a nicer history tree :)

git cherry-pickWhen you just need one specific commit, git cherry-pick is a nice solution (the -x option appends a line that says "(cherry picked from commit...)" to the original commit message body, so it's usually a good idea to use it - git log <commit_sha1> to see it):

git pull --rebaseI am not sure I can explain it better than Derek Gourlay... Basically, use git pull --rebase instead of git pull :) What's missing in the article though, is that you can enable it by default:
git config --global pull.rebase true
git rerereAgain, nicely explained here. But put simply, if you enable it, you won't have to resolve the same conflict multiple times anymore.
It means that you have a memory error. You may be trying to free a pointer that wasn't allocated by malloc (or delete an object that wasn't created by new) or you may be trying to free/delete such an object more than once. You may be overflowing a buffer or otherwise writing to memory to which you shouldn't be writing, causing heap corruption.
Any number of programming errors can cause this problem. You need to use a debugger, get a backtrace, and see what your program is doing when the error occurs. If that fails and you determine you have corrupted the heap at some previous point in time, you may be in for some painful debugging (it may not be too painful if the project is small enough that you can tackle it piece by piece).
The problem here is the line 292 (Using Python 3.4.3 here) in $python_install_prefix/Lib/distutils/msvc9compiler.py which says:
VERSION = get_build_version()
This only checks for the MSVC version that your python was built with. Just replacing this line with your actual Visual Studio version, eg. 12.0 for MSVC2013
VERSION = 12.0
will fix the issue.
UPDATE: Turns out that there is a good reason why this version is hardcoded. MSVC C runtime is not required to be compatible between major versions. Hence when you use a different VS version you might run into runtime problems. So I advise to use VS 2008 (for Python 2.6 up to 3.2) and VS2010 for (Python 3.3 and later) until this issue is sorted out.
Binary compatibility will arrive with VS 2015 (see here) along with Python 3.5 .
For Python 2.7 users Microsoft released a special Microsoft Visual C++ Compiler for Python 2.7 which can be used without installing the whole VS 2008.
Sounds like you're just trying to do a classic two-column lookup. http://www.dailydoseofexcel.com/archives/2009/04/21/vlookup-on-two-columns/
Tons of solutions for this, most simple is probably the following (which doesn't require an array formula):
=SUMPRODUCT((Lookup!A:A=Param!A1)*(Lookup!B:B=Param!B1)*(Lookup!C:C))
To translate your specific example, you would use:
=SUMPRODUCT((A1:A3=A2)*(B1:B3="B")*(C1:C3))
I would like to add a solution, that have helpt me to solve this problem in entity framework:
var eventsCustom = eventCustomRepository.FindAllEventsCustomByUniqueStudentReference(userDevice.UniqueStudentReference)
.Where(x => x.DateTimeStart.Year == currentDateTime.Year &&
x.DateTimeStart.Month== currentDateTime.Month &&
x.DateTimeStart.Day == currentDateTime.Day
);
I hope that it helps.
Converting a string to an int is more complicated than just converting a number. You have think about the following issues:
You can always apply CCS class with rotate property - http://css-tricks.com/snippets/css/text-rotation/
To keep rotated image within your div dimensions you need to adjust CSS as well, there is no needs to use JavaScript except of adding class.
adb logcat -c
Logcat options are documented here: http://developer.android.com/tools/help/logcat.html
If you'd like to initialize the array to values other than 0, with gcc you can do:
int array[1024] = { [ 0 ... 1023 ] = -1 };
This is a GNU extension of C99 Designated Initializers. In older GCC, you may need to use -std=gnu99 to compile your code.
Don't.
Use a regex for a quick sanity check, something like .@.., but almost all langauges / frameworks have better methods for checking an e-mail address. Use that.
It is possible to validate an e-mail address with a regex, but it is a long regex. Very long.
And in the end you will be none the wiser. You'll only know that the format is valid, but you still don't know if it's an active e-mail address. The only way to find out, is by sending a confirmation e-mail.
There is a VSCode extension called "Python Auto Venv" that automatically detects and uses your virtual environment if there is one.
For me this error was simply because boost wasn't installed so on ubuntu:
sudo apt install build-essential libboost-system-dev libboost-thread-dev libboost-program-options-dev libboost-test-dev
For the latest (Juno) eclipse cdt the following worked for me, no need to declare __GXX_EXPERIMENTAL_CXX0X__ on myself. This works for the the CDT indexer and as parameter for the compiler:
"your project name" -> right click -> properties:
C/C++ General -> Preprocessor Include Paths, Macros etc. -> switch to the tab named "Providers":
for "Configuration" select "Release" (and afterwards "debug")
switch off all providers and just select "CDT GCC Built-in Compiler Settings"
uncheck "Share setting entries between projects (global provider)"
in the "Command to get compiler specs:" add "-std=c++11" without the quotes (may work with quotes too)
hit apply and close the options
rebuild the index
Now all the c++11 related stuff should be resolved correctly by the indexer.

It is not possible to return an array from a C++ function. 8.3.5[dcl.fct]/6:
Functions shall not have a return type of type array or function[...]
Most commonly chosen alternatives are to return a value of class type where that class contains an array, e.g.
struct ArrayHolder
{
int array[10];
};
ArrayHolder test();
Or to return a pointer to the first element of a statically or dynamically allocated array, the documentation must indicate to the user whether he needs to (and if so how he should) deallocate the array that the returned pointer points to.
E.g.
int* test2()
{
return new int[10];
}
int* test3()
{
static int array[10];
return array;
}
While it is possible to return a reference or a pointer to an array, it's exceedingly rare as it is a more complex syntax with no practical advantage over any of the above methods.
int (&test4())[10]
{
static int array[10];
return array;
}
int (*test5())[10]
{
static int array[10];
return &array;
}
Ubuntu 12.04's Eclipse was so broken for me I couldn't get M2E to install. The only way to fixed it was by using the official tar archive from the eclipse download page after purging all the ubuntu eclipse packages. - Cheers
you should use regular expressions to find all you need:
import re
p = re.compile(r'(\d+)') # a pattern for a number
for line in file :
if num in p.findall(line) :
print line
regular expression will return you all numbers in a line as a list, for example:
>>> re.compile(r'(\d+)').findall('123kh234hi56h9234hj29kjh290')
['123', '234', '56', '9234', '29', '290']
so you don't match '200' or '220' for '20'.
Just to add to answers by Mr. Dimitrov and Jason, if you are using a specific profile and you have put your region setting there,then for all the requests you need to add
"--profile" option.
For example:
Lets say you have AWS Playground profile, and the ~/.aws/config has [profile playground] which further has something like,
[profile playground]
region=us-east-1
then, use something like below
aws ecs list-container-instances --cluster default --profile playground
When you generate a JAXB model from an XML Schema, global elements that correspond to named complex types will have that metadata captured as an @XmlElementDecl annotation on a create method in the ObjectFactory class. Since you are creating the JAXBContext on just the DocumentType class this metadata isn't being processed. If you generated your JAXB model from an XML Schema then you should create the JAXBContext on the generated package name or ObjectFactory class to ensure all the necessary metadata is processed.
Example solution:
JAXBContext jaxbContext = JAXBContext.newInstance(my.generatedschema.dir.ObjectFactory.class);
DocumentType documentType = ((JAXBElement<DocumentType>) jaxbContext.createUnmarshaller().unmarshal(inputStream)).getValue();

If none of these worked, close android studio and then go to
C:\Users\User.AndroidStudio(ANDROID_STUDIO_VERSION)\system and delete the caches folder
Restart your project now, it should work.
An even more efficient way is streaming by asking the operating system’s kernel to open a file, then read bytes from it bit by bit. When reading a file per line in Ruby, data is taken from the file 512 bytes at a time and split up in “lines” after that.
By buffering the file’s content, the number of I/O calls is reduced while dividing the file in logical chunks.
Example:
Add this class to your app as a service object:
class MyIO
def initialize(filename)
fd = IO.sysopen(filename)
@io = IO.new(fd)
@buffer = ""
end
def each(&block)
@buffer << @io.sysread(512) until @buffer.include?($/)
line, @buffer = @buffer.split($/, 2)
block.call(line)
each(&block)
rescue EOFError
@io.close
end
end
Call it and pass the :each method a block:
filename = './somewhere/large-file-4gb.txt'
MyIO.new(filename).each{|x| puts x }
Read about it here in this detailed post:
More things can be done with keyboard module.
You can install this module using pip install keyboard
Here are some of the methods:
Using the function read_key():
import keyboard
while True:
if keyboard.read_key() == "p":
print("You pressed p")
break
This is gonna break the loop as the key p is pressed.
Using function wait:
import keyboard
keyboard.wait("p")
print("You pressed p")
It will wait for you to press p and continue the code as it is pressed.
Using the function on_press_key:
import keyboard
keyboard.on_press_key("p", lambda _:print("You pressed p"))
It needs a callback function. I used _ because the keyboard function returns the keyboard event to that function.
Once executed, it will run the function when the key is pressed. You can stop all hooks by running this line:
keyboard.unhook_all()
This method is sort of already answered by user8167727 but I disagree with the code they made. It will be using the function is_pressed but in an other way:
import keyboard
while True:
if keyboard.is_pressed("p"):
print("You pressed p")
break
It will break the loop as p is pressed.
Notes:
keyboard will read keypresses from the whole OS.keyboard requires root on linuxUsing the command line:
Enter ls -al ~/.ssh to see if existing SSH keys are present.
In the terminal is shows: No directory exist
Then generate a new SSH key
Step 1.
ssh-keygen -t rsa -b 4096 -C "[email protected]"
step 2.
Enter a file in which to save the key (/Users/you/.ssh/id_rsa): <here is file name and enter the key>
step 3.
Enter passphrase (empty for no passphrase): [Type a password]
Enter same passphrase again: [Type password again]
Mandatory: Have the first value empty - required works on empty values
Prerequisites: correct html5 DOCTYPE and a named input field
<select name="somename" required>
<option value="">Please select</option>
<option value="one">One</option>
</select>
As per the documentation (the listing and bold is mine)
The required attribute is a boolean attribute.
When specified, the user will be required to select a value before submitting the form.If a select element
- has a required attribute specified,
- does not have a multiple attribute specified,
- and has a display size of 1 (do not have SIZE=2 or more - omit it if not needed);
- and if the value of the first option element in the select element's list of options (if any) is the empty string (i.e. present as
value=""),- and that option element's parent node is the select element (and not an optgroup element),
then that option is the select element's placeholder label option.
You can also convert that attribute as case sensitive using this syntax :
ALTER TABLE Table1
ALTER COLUMN Column1 VARCHAR(200)
COLLATE SQL_Latin1_General_CP1_CS_AS
Now your search will be case sensitive.
If you want to make that column case insensitive again, then use
ALTER TABLE Table1
ALTER COLUMN Column1 VARCHAR(200)
COLLATE SQL_Latin1_General_CP1_CI_AS
Rotating the labels is certainly possible. Note though that doing so reduces the readability of the text. One alternative is to alternate label positions using a code like this:
import numpy as np
n=5
x = np.arange(n)
y = np.sin(np.linspace(-3,3,n))
xlabels = ['Long ticklabel %i' % i for i in range(n)]
fig, ax = plt.subplots()
ax.plot(x,y, 'o-')
ax.set_xticks(x)
labels = ax.set_xticklabels(xlabels)
for i, label in enumerate(labels):
label.set_y(label.get_position()[1] - (i % 2) * 0.075)
For more background and alternatives, see this post on my blog

Like @Ardee said you sharer.php uses data from the meta tags, the Dialog API accepts parameters. Facebook have removed the ability to use the message parameter but you can use the quote parameter which can be useful in a lot of cases e.g.
https://www.facebook.com/dialog/share?
app_id=[your-app-id]
&display=popup
&title=This+is+the+title+parameter
&description=This+is+the+description+parameter
"e=This+is+the+quote+parameter

&href=https%3A%2F%2Fdevelopers.facebook.com%2Fdocs%2F
&redirect_uri=https%3A%2F%2Fwww.[url-in-your-accepted-list].com
Just have to create an app id:
https://developers.facebook.com/docs/apps/register
Then make sure the redirect url domain is listed in the accepted domains for that app.

It's old question but just in case someone bump on this tread...
var input = document.getElementById("your_input");
var file = input.value.split("\\");
var fileName = file[file.length-1];
No need for regex, jQuery....
I think clang could be an alternative.
GCC and clang have some differences on expressions like a+++++a, and I've got many different answers with my peer who use clang on Mac while I use gcc.
GCC has become the standard, and clang could be an alternative. Because GCC is very stable and clang is still under developing.
This is a quick hacky way: ls -lart | grep -v ^total.
Basically, remove any lines that start with "total", which in ls output should only be the first line.
A more general way (for anything):
ls -lart | sed "1 d"
sed "1 d" means only print everything but first line.
The accepted answer works but leaves an empty style attribute on the DOM in my tests. No big deal, but this removes it all:
removeAttr( 'style' );
This assumes you want to remove all dynamic styling and return back to the stylesheet styling.
Come on guys, there is no need to loop, just use simple math to solve this equation system:
a*b = i;
a+b = j;
a = j/b;
a = i-b;
j/b = i-b; so:
b + j/b + i = 0
b^2 + i*b + j = 0
From here, its a quadratic equation, and it's trivial to find b (just implement the quadratic equation formula) and from there get the value for a.
EDIT:
There you go:
function finder($add,$product)
{
$inside_root = $add*$add - 4*$product;
if($inside_root >=0)
{
$b = ($add + sqrt($inside_root))/2;
$a = $add - $b;
echo "$a+$b = $add and $a*$b=$product\n";
}else
{
echo "No real solution\n";
}
}

I'm having this problem myself - my page breaks work in every browser but Chrome - and was able to isolate it down to the page-break-after element being inside a table cell. (Old, inherited templates in the CMS.)
Apparently Chrome doesn't honor the page-break-before or page-break-after properties inside table cells, so this modified version of Phil's example puts the second and third headline on the same page:
<!DOCTYPE html>
<html>
<head>
<meta http-equiv="content-type" content="text/html;charset=UTF-8" />
<title>Paginated HTML</title>
<style type="text/css" media="print">
div.page
{
page-break-after: always;
page-break-inside: avoid;
}
</style>
</head>
<body>
<div class="page">
<h1>This is Page 1</h1>
</div>
<table>
<tr>
<td>
<div class="page">
<h1>This is Page 2</h1>
</div>
<div class="page">
<h1>This is, sadly, still Page 2</h1>
</div>
</td>
</tr>
</table>
</body>
</html>
Chrome's implementation is (dubiously) allowed given the CSS specification - you can see more here: http://www.google.com/support/forum/p/Chrome/thread?tid=32f9d9629d6f6789&hl=en
Let arrList be the ArrayList and newValue the new String, then just do:
arrList.set(5, newValue);
This can be found in the java api reference here.
require_relative is a convenient subset of require
require_relative('path')
equals:
require(File.expand_path('path', File.dirname(__FILE__)))
if __FILE__ is defined, or it raises LoadError otherwise.
This implies that:
require_relative 'a' and require_relative './a' require relative to the current file (__FILE__).
This is what you want to use when requiring inside your library, since you don't want the result to depend on the current directory of the caller.
eval('require_relative("a.rb")') raises LoadError because __FILE__ is not defined inside eval.
This is why you can't use require_relative in RSpec tests, which get evaled.
The following operations are only possible with require:
require './a.rb' requires relative to the current directory
require 'a.rb' uses the search path ($LOAD_PATH) to require. It does not find files relative to current directory or path.
This is not possible with require_relative because the docs say that path search only happens when "the filename does not resolve to an absolute path" (i.e. starts with / or ./ or ../), which is always the case for File.expand_path.
The following operation is possible with both, but you will want to use require as it is shorter and more efficient:
require '/a.rb' and require_relative '/a.rb' both require the absolute path.Reading the source
When the docs are not clear, I recommend that you take a look at the sources (toggle source in the docs). In some cases, it helps to understand what is going on.
require:
VALUE rb_f_require(VALUE obj, VALUE fname) {
return rb_require_safe(fname, rb_safe_level());
}
require_relative:
VALUE rb_f_require_relative(VALUE obj, VALUE fname) {
VALUE base = rb_current_realfilepath();
if (NIL_P(base)) {
rb_loaderror("cannot infer basepath");
}
base = rb_file_dirname(base);
return rb_require_safe(rb_file_absolute_path(fname, base), rb_safe_level());
}
This allows us to conclude that
require_relative('path')
is the same as:
require(File.expand_path('path', File.dirname(__FILE__)))
because:
rb_file_absolute_path =~ File.expand_path
rb_file_dirname1 =~ File.dirname
rb_current_realfilepath =~ __FILE__
Have you looked into ControlsFx Popover control.
import org.controlsfx.control.PopOver;
import org.controlsfx.control.PopOver.ArrowLocation;
private PopOver item;
final Scene scene = addItemButton.getScene();
final Point2D windowCoord = new Point2D(scene.getWindow()
.getX(), scene.getWindow().getY());
final Point2D sceneCoord = new Point2D(scene.getX(), scene.
getY());
final Point2D nodeCoord = addItemButton.localToScene(0.0,
0.0);
final double clickX = Math.round(windowCoord.getX()
+ sceneCoord.getY() + nodeCoord.getX());
final double clickY = Math.round(windowCoord.getY()
+ sceneCoord.getY() + nodeCoord.getY());
item.setContentNode(addItemScreen);
item.setArrowLocation(ArrowLocation.BOTTOM_LEFT);
item.setCornerRadius(4);
item.setDetachedTitle("Add New Item");
item.show(addItemButton.getParent(), clickX, clickY);
This is only an example but a PopOver sounds like it could accomplish what you want. Check out the documentation for more info.
Important note: ControlsFX will only work on JavaFX 8.0 b118 or later.

Simple assigning to window.location or window.location.href should be fine:
window.location = newUrl;
However, your new URL will cause the browser to load the new page, but it sounds like you'd like to modify the URL without leaving the current page. You have two options for this:
Use the URL hash. For example, you can go from example.com to example.com#foo without loading a new page. You can simply set window.location.hash to make this easy. Then, you should listen to the HTML5 hashchange event, which will be fired when the user presses the back button. This is not supported in older versions of IE, but check out jQuery BBQ, which makes this work in all browsers.
You could use HTML5 History to modify the path without reloading the page. This will allow you to change from example.com/foo to example.com/bar. Using this is easy:
window.history.pushState("example.com/foo");
When the user presses "back", you'll receive the window's popstate event, which you can easily listen to (jQuery):
$(window).bind("popstate", function(e) { alert("location changed"); });
Unfortunately, this is only supported in very modern browsers, like Chrome, Safari, and the Firefox 4 beta.
I had to create an array of a predefined type, and I successfully did as follows:

Solution I use for years with no issues at all. First of all I extend UIWindow to find it's visibleViewController. NOTE: if you using custom collection* classes (such as side menu) you should add handler for this case in following extension. After getting top most view controller it's easy to present UIAlertController just like UIAlertView.
extension UIAlertController {
func show(animated: Bool = true, completion: (() -> Void)? = nil) {
if let visibleViewController = UIApplication.shared.keyWindow?.visibleViewController {
visibleViewController.present(self, animated: animated, completion: completion)
}
}
}
extension UIWindow {
var visibleViewController: UIViewController? {
guard let rootViewController = rootViewController else {
return nil
}
return visibleViewController(for: rootViewController)
}
private func visibleViewController(for controller: UIViewController) -> UIViewController {
var nextOnStackViewController: UIViewController? = nil
if let presented = controller.presentedViewController {
nextOnStackViewController = presented
} else if let navigationController = controller as? UINavigationController,
let visible = navigationController.visibleViewController {
nextOnStackViewController = visible
} else if let tabBarController = controller as? UITabBarController,
let visible = (tabBarController.selectedViewController ??
tabBarController.presentedViewController) {
nextOnStackViewController = visible
}
if let nextOnStackViewController = nextOnStackViewController {
return visibleViewController(for: nextOnStackViewController)
} else {
return controller
}
}
}
This is a recursive way that removes multiple occurrences of "endchar":
function TrimEnd(str, endchar) {_x000D_
while (str.endsWith(endchar) && str !== "" && endchar !== "") {_x000D_
str = str.slice(0, -1);_x000D_
}_x000D_
return str;_x000D_
}_x000D_
_x000D_
var res = TrimEnd("Look at me. I'm a string without dots at the end...", ".");_x000D_
console.log(res)For me the issue was that I had two Visual Studio windows opened, my project was running in debug in one window, and I tried to build it in another.
I had to stop debugging and then it let me build successfully.
If the current directory is empty, you can do that with:
git clone git@github:me/name.git .
(Note the . at the end to specify the current directory.) Of course, this also creates the .git directory in your current folder, not just the source code from your project.
This optional [directory] parameter is documented in the git clone manual page, which points out that cloning into an existing directory is only allowed if that directory is empty.
Try getting Spring to inject it, assuming you're using Spring as a dependency-injection framework.
In your class, do something like this:
public void setSqlResource(Resource sqlResource) {
this.sqlResource = sqlResource;
}
And then in your application context file, in the bean definition, just set a property:
<bean id="someBean" class="...">
<property name="sqlResource" value="classpath:com/somecompany/sql/sql.txt" />
</bean>
And Spring should be clever enough to load up the file from the classpath and give it to your bean as a resource.
You could also look into PropertyPlaceholderConfigurer, and store all your SQL in property files and just inject each one separately where needed. There are lots of options.
Recursion is not necessary, here is good information about this solution.
var values1 = new[] { 1, 2, 3, 4, 5 };
foreach (var permutation in values1.GetPermutations())
{
Console.WriteLine(string.Join(", ", permutation));

var values2 = new[] { 'a', 'b', 'c', 'd', 'e' };
foreach (var permutation in values2.GetPermutations())

I think my solution to this might be the simplest. On my development machine, I added a fake domain in my hosts file similar to http://myfakedomain.notarealtld and set it to 127.0.0.1. Then I changed my server's CORS configuration (in my case an S3 bucket) to allow that domain. That way I can use Chrome on localhost and it works great.
Make sure your CORS configuration takes into account the entire hostname with port, ie. http://myfakedomain.notarealtld:3000
You can modify your hosts file easily on Linux, Mac, and Windows.
I am now running OS Big Sur. xcode-select --install, and sudo xcode-select --reset did not resolve my issue, neither did the recommended subsequent softwareupdate --install -a command. For good measure, I tried the recommended download from Apple Downloads, but the Command Line Tools downloads available there are not compatible with my OS.
I upvoted the fix that resolved for me, sudo xcode-select --switch /Library/Developer/CommandLineTools/ and added this post for environment context.
If number is int use
"" + parseInt(str)
If the number is float use
"" + parseFloat(str)
To detect Internet Explorer 10|11 you can use this little script immediatelly after body tag:
In my case i use jQuery library loaded in head.

</head>
<body>
<script>if (navigator.appVersion.indexOf('Trident/') != -1) $("body").addClass("ie10");</script>

Linq.Min() / Linq.Max() approach:
DateTime date1 = new DateTime(2000,1,1);
DateTime date2 = new DateTime(2001,1,1);
DateTime minresult = new[] { date1,date2 }.Min();
DateTime maxresult = new[] { date1,date2 }.Max();
This is not an answer to the question but as I found this page while looking to an answer to a problem that I had, I want to mention the solution that I found as it cost me a lot of time. In the hope this will be useful to others:
The problem was that text in a <p> tag would not fold in the div. Eventually, I opened the inspector and noticed a 'no breaking space entity' between all the words. My editor, vi, was just showing normal blank spaces (some invisible chr, I don't know what) but I had copied pasted the text from a PDF document. The solution was to copy a blank space from within vi and replace it with a blank space. ie. :%s/ / /g where the blank to be replaced was copied from the offending text. Problem solved.
firstSet.equals(secondSet)
It really depends on what you want to do in the comparison logic... ie what happens if you find an element in one set not in the other? Your method has a void return type so I assume you'll do the necessary work in this method.
More fine-grained control if you need it:
if (!firstSet.containsAll(secondSet)) {
// do something if needs be
}
if (!secondSet.containsAll(firstSet)) {
// do something if needs be
}
If you need to get the elements that are in one set and not the other.
EDIT: set.removeAll(otherSet) returns a boolean, not a set. To use removeAll(), you'll have to copy the set then use it.
Set one = new HashSet<>(firstSet);
Set two = new HashSet<>(secondSet);
one.removeAll(secondSet);
two.removeAll(firstSet);
If the contents of one and two are both empty, then you know that the two sets were equal. If not, then you've got the elements that made the sets unequal.
You mentioned that the number of records might be high. If the underlying implementation is a HashSet then the fetching of each record is done in O(1) time, so you can't really get much better than that. TreeSet is O(log n).
Another alternative is
dtColumns[index].visible = false/true;
To show or hide any column.
Hello I realize this post is old, but here is my opinion anyway. This error arises when you close the console output window using the close icon instead of pressing "any key to continue"
If you pass the -v flag to the ansible-playbook command, then ansible will show the output on your terminal.
For your use case, you may want to try using the fetch module to copy the public key from the server to your local machine. That way, it will only show a "changed" status when the file changes.

You can use fireEvent on IE 8 or lower, and W3C's dispatchEvent on most other browsers. To create the event you want to fire, you can use either createEvent or createEventObject depending on the browser.
Here is a self-explanatory piece of code (from prototype) that fires an event dataavailable on an element:
var event; // The custom event that will be created
if(document.createEvent){
event = document.createEvent("HTMLEvents");
event.initEvent("dataavailable", true, true);
event.eventName = "dataavailable";
element.dispatchEvent(event);
} else {
event = document.createEventObject();
event.eventName = "dataavailable";
event.eventType = "dataavailable";
element.fireEvent("on" + event.eventType, event);
}
To say what others have in a different way: yes, it is a decorator.
In Python, it's like:
This can be used for all kinds of useful things, made possible because functions are objects and just necessary just instructions.

I'm thinking something like, just give an idea, to convert the column to string, and work with string is easier. however this does not work with strings containing numbers, like bad123. and ~ is taking the complement of selection.
df['a'] = df['a'].astype(str)
df[~df['a'].str.contains('0|1|2|3|4|5|6|7|8|9')]
df['a'] = df['a'].astype(object)
and using '|'.join([str(i) for i in range(10)]) to generate '0|1|...|8|9'
or using np.isreal() function, just like the most voted answer
df[~df['a'].apply(lambda x: np.isreal(x))]
The following worked for me:
Registry Editor (press windows key, type regedit and hit Enter) .HKEY_CURRENT_USER\Software\Microsoft\Command Processor\AutoRun and clear the values.HKEY_LOCAL_MACHINE\Software\Microsoft\Command Processor\AutoRun.Using appendEncodePath() could save you multiple lines than appendPath(), the following code snippet builds up this url: http://api.openweathermap.org/data/2.5/forecast/daily?zip=94043

If you specify image as well as build, then Compose names the built image with the webapp and optional tag specified in image:
build: ./dir
image: webapp:tag
This results in an image named webapp and tagged tag, built from ./dir.
Based on csharptest.net's great answer, I have written a Class for this:

}
Usage:
// Hash
var hash = SecurePasswordHasher.Hash("mypassword");
// Verify
var result = SecurePasswordHasher.Verify("mypassword", hash);
A sample hash could be this:
$MYHASH$V1$10000$Qhxzi6GNu/Lpy3iUqkeqR/J1hh8y/h5KPDjrv89KzfCVrubn
As you can see, I also have included the iterations in the hash for easy usage and the possibility to upgrade this, if we need to upgrade.

For setting row height there is separate method:
For Swift 3
func tableView(_ tableView: UITableView, heightForRowAt indexPath: IndexPath) -> CGFloat {
return 100.0;//Choose your custom row height
}
Older Swift uses
func tableView(tableView: UITableView, heightForRowAtIndexPath indexPath: NSIndexPath) -> CGFloat {
return 100.0;//Choose your custom row height
}
Otherwise you can set row height using:
self.tableView.rowHeight = 44.0

val editText = findViewById(R.id.edittext_id) as EditText
editText.setSelection(editText.text.length)
Below Code is to place the cursor after the second character:
val editText = findViewById(R.id.edittext_id) as EditText
editText.setSelection(2)
JAVA:
set the cursor to the starting position:
EditText editText = (EditText)findViewById(R.id.edittext_id);
editText.setSelection(0);
set the cursor to the end of the EditText:
EditText editText = (EditText)findViewById(R.id.edittext_id);
editText.setSelection(editText.getText().length());
Below Code is to place the cursor after the second character:
EditText editText = (EditText)findViewById(R.id.edittext_id);
editText.setSelection(2);
On thing to remember here is that the default param must be the last param in the function definition.
Following code will not compile:
void fun(int first, int second = 10, int third);
Following code will compile:
void fun(int first, int second, int third = 10);
You can use step-down as I describe in the links you refer to but you appear to use them in a wrong way.
Step down is not needed to scale images to ratios above 1:2 (typically, but not limited to). It is where you need to do a drastic down-scaling you need to split it up in two (and rarely, more) steps depending on content of the image (in particular where high-frequencies such as thin lines occur).
Every time you down-sample an image you will loose details and information. You cannot expect the resulting image to be as clear as the original.
If you are then scaling down the images in many steps you will loose a lot of information in total and the result will be poor as you already noticed.
Try with just one extra step, or at tops two.
In case of Photoshop notice that it applies a convolution after the image has been re-sampled, such as sharpen. It's not just bi-cubic interpolation that takes place so in order to fully emulate Photoshop we need to also add the steps Photoshop is doing (with the default setup).
For this example I will use my original answer that you refer to in your post, but I have added a sharpen convolution to it to improve quality as a post process (see demo at bottom).
Here is code for adding sharpen filter (it's based on a generic convolution filter - I put the weight matrix for sharpen inside it as well as a mix factor to adjust the pronunciation of the effect):
Usage:
sharpen(context, width, height, mixFactor);
The mixFactor is a value between [0.0, 1.0] and allow you do downplay the sharpen effect - rule-of-thumb: the less size the less of the effect is needed.
Function (based on this snippet):
function sharpen(ctx, w, h, mix) {
var weights = [0, -1, 0, -1, 5, -1, 0, -1, 0],
katet = Math.round(Math.sqrt(weights.length)),
half = (katet * 0.5) |0,
dstData = ctx.createImageData(w, h),
dstBuff = dstData.data,
srcBuff = ctx.getImageData(0, 0, w, h).data,
y = h;
while(y--) {
x = w;
while(x--) {
var sy = y,
sx = x,
dstOff = (y * w + x) * 4,
r = 0, g = 0, b = 0, a = 0;
for (var cy = 0; cy < katet; cy++) {
for (var cx = 0; cx < katet; cx++) {
var scy = sy + cy - half;
var scx = sx + cx - half;
if (scy >= 0 && scy < h && scx >= 0 && scx < w) {
var srcOff = (scy * w + scx) * 4;
var wt = weights[cy * katet + cx];
r += srcBuff[srcOff] * wt;
g += srcBuff[srcOff + 1] * wt;
b += srcBuff[srcOff + 2] * wt;
a += srcBuff[srcOff + 3] * wt;
}
}
}
dstBuff[dstOff] = r * mix + srcBuff[dstOff] * (1 - mix);
dstBuff[dstOff + 1] = g * mix + srcBuff[dstOff + 1] * (1 - mix);
dstBuff[dstOff + 2] = b * mix + srcBuff[dstOff + 2] * (1 - mix)
dstBuff[dstOff + 3] = srcBuff[dstOff + 3];
}
}
ctx.putImageData(dstData, 0, 0);
}
The result of using this combination will be:
Depending on how much of the sharpening you want to add to the blend you can get result from default "blurry" to very sharp:
If you want to get the best result quality-wise you'll need to go low-level and consider to implement for example this brand new algorithm to do this.
See Interpolation-Dependent Image Downsampling (2011) from IEEE.
Here is a link to the paper in full (PDF).
There are no implementations of this algorithm in JavaScript AFAIK of at this time so you're in for a hand-full if you want to throw yourself at this task.
The essence is (excerpts from the paper):
Abstract
An interpolation oriented adaptive down-sampling algorithm is proposed for low bit-rate image coding in this paper. Given an image, the proposed algorithm is able to obtain a low resolution image, from which a high quality image with the same resolution as the input image can be interpolated. Different from the traditional down-sampling algorithms, which are independent from the interpolation process, the proposed down-sampling algorithm hinges the down-sampling to the interpolation process. Consequently, the proposed down-sampling algorithm is able to maintain the original information of the input image to the largest extent. The down-sampled image is then fed into JPEG. A total variation (TV) based post processing is then applied to the decompressed low resolution image. Ultimately, the processed image is interpolated to maintain the original resolution of the input image. Experimental results verify that utilizing the downsampled image by the proposed algorithm, an interpolated image with much higher quality can be achieved. Besides, the proposed algorithm is able to achieve superior performance than JPEG for low bit rate image coding.

You may probably do this way
var currentMonth = new Date().getMonth();
var monthNames = ["January", "February", "March", "April", "May", "June",
"July", "August", "September", "October", "November", "December"
];
for(var i = currentMonth-1 ; i<= 4; i++){
console.log(monthNames[i])// make it as an array of objects here
}
you have missed the Fingerprint Certificate Authorization dialog in your phone when you connected it, try to change the USB mode to Media, or another different than the one you have in and then reconnect your device, or go to Developer Options -> Revoke USB Debugging and reconnect, watch for the dialog and click on accept, that should solve your problems.
If that doesn't work, set your ANDROID_SDK_HOME again, and then:
Run:
adb kill-server
adb start-server

The functionality, you described, can be easily achieved using the Bootstrap tooltip.
<button id="example1" data-toggle="tooltip">Tooltip on left</button>
Then call tooltip() function for the element.
$('#example1').tooltip();
If new does the job for you, then it will make your code modestly smaller as well. If you would otherwise call [[SomeClass alloc] init] in many different places in your code, you will create a Hot Spot in new's implementation - that is, in the objc runtime - that will reduce the number of your cache misses.
In my understanding, if you need to use a custom initializer use [[SomeClass alloc] initCustom].
If you don't, use [SomeClass new].
A browser will only open a tab/popup without the popup blocker warning if the command to open the tab/popup comes from a trusted event. That means the user has to actively click somewhere to open a popup.
In your case, the user performs a click so you have the trusted event. You do lose that trusted context, however, by performing the Ajax request. Your success handler does not have that event anymore. The only way to circumvent this is to perform a synchronous Ajax request which will block your browser while it runs, but will preserve the event context.
In jQuery this should do the trick:
$.ajax({
url: 'http://yourserver/',
data: 'your image',
success: function(){window.open(someUrl);},
async: false
});
Here is your answer: Open new tab without popup blocker after ajax call on user click
Go to the MinGW http sourceforge.net tree. Under Home/MinGW/Base/gcc/Version4(or whatever version use are using)/gcc-4(version)/ you'll find a file like gcc-core-4.8.1-4-mingw32-dll.tar.lzma. Extract it and go into the bin folder where you'll find your libgcc_s_dw2-1.dll and other dll's. Copy and paste what you need into your bin directory.
In my case I was having an issue where the table was not being displayed right after the paragraph I inserted it, so I simply changed
\begin{table}[]
to
\begin{table}[ht]
Your class doesn't have a __init__(), so by the time it's instantiated, the attribute atoms is not present. You'd have to do C.setdata('something') so C.atoms becomes available.
>>> C = Residues()
>>> C.atoms.append('thing')
Traceback (most recent call last):
File "<pyshell#84>", line 1, in <module>
B.atoms.append('thing')
AttributeError: Residues instance has no attribute 'atoms'
>>> C.setdata('something')
>>> C.atoms.append('thing') # now it works
>>>
Unlike in languages like Java, where you know at compile time what attributes/member variables an object will have, in Python you can dynamically add attributes at runtime. This also implies instances of the same class can have different attributes.
To ensure you'll always have (unless you mess with it down the line, then it's your own fault) an atoms list you could add a constructor:
def __init__(self):
self.atoms = []
Update: In EF 6.2 there is a like operator
Where(obj => DbFunctions.Like(obj.Column , "%expression%")
As Ric already mentioned in his post you can set the render mode in code, you can also do this directly in the image catalog, see attached image below. Just set the Render As to Template Image
Caveat I have had problems with iOS 7 and this approach. So if you use iOS 7 as well you might want to do it in code as well to be sure, as described here.
You can invoke MySQL show status command
show status like 'Conn%';

The class attribute can be used with multiple HTML elements/tags and all will take the effect. Where as the id is meant for a single element/tag and is considered unique.
Moreoever the id has a higher specificity value than the class.
Something like...
Minutes.minutesBetween(getStart(), getEnd()).getMinutes();
I made a generic component where I need a reference to the parent using it. Here's what I came up with:
In my component I made an @Input :
@Input()
parent: any;
Then In the parent using this component:
<app-super-component [parent]="this"> </app-super-component>
In the super component I can use any public thing coming from the parent:
Attributes:
parent.anyAttribute
Functions :
parent[myFunction](anyParameter)
and of course private stuff won't be accessible.
I have a .Net Core 3.1 MSTest project with similar issue. This post provided clues to fix it.
Breaking this down to a simple answer for .Net core 3.1:
If it is a MSTest project:
rename file in project to testhost.dll.config
OR
Use post-build command provided by DeepSpace101
In my case, sometimes when i tests my MVC project by a localhost https url (E.g. https://localhost:44373/), the Chrome raise this error: net::ERR_INSECURE_RESPONSE for the website resources (such as JS files).
So i resolve it by Clear Cache. Then i refresh the page and Chrome show me a special page about insecure url and i just allow it by click on Proceed to localhost (unsafe).
If you use GitHub Desktop, you can do it easily in just 6 steps (actually only 5).
Once you open Github Desktop and choose your repository,
master / branch-name, based on your active branch.Checkout the GIF below as an example:
Try following code:
File file = new File("infilename");
// Get the number of bytes in the file
long sizeInBytes = file.length();
//transform in MB
long sizeInMb = sizeInBytes / (1024 * 1024);
additional info:
http://maps.google.com/maps?q=loc: put in latitude and longitude after, example:
http://maps.google.com/maps?q=loc:51.03841,-114.01679
this will show pointer on map, but will suppress geocoding of the address, best for a location without an address, or for a location where google maps shows the incorrect address.
As said earlier, your code will work unless you have the same classes loaded on two different class loaders. This might happen in case you need multiple versions of the same class in memory at the same time, or you are doing some weird on the fly compilation stuff (as I am).
In this case, if you want to consider these as the same class (which might be reasonable depending on the case), you can match their names to compare them.
public static boolean areClassesQuiteTheSame(Class<?> c1, Class<?> c2) {
// TODO handle nulls maybe?
return c1.getCanonicalName().equals(c2.getCanonicalName());
}
Keep in mind that this comparison will do just what it does: compare class names; I don't think you will be able to cast from one version of a class to the other, and before looking into reflection, you might want to make sure there's a good reason for your classloader mess.
Ahh... nevermind. It's always the search after the question is posed that yields the answer. My object that is being serialized is obj and has already been defined. Adding an XMLSerializerNamespace with a single empty namespace to the collection does the trick.
In VB like this:
Dim xs As New XmlSerializer(GetType(cEmploymentDetail))
Dim ns As New XmlSerializerNamespaces()
ns.Add("", "")
Dim settings As New XmlWriterSettings()
settings.OmitXmlDeclaration = True
Using ms As New MemoryStream(), _
sw As XmlWriter = XmlWriter.Create(ms, settings), _
sr As New StreamReader(ms)
xs.Serialize(sw, obj, ns)
ms.Position = 0
Console.WriteLine(sr.ReadToEnd())
End Using
in C# like this:
//Create our own namespaces for the output
XmlSerializerNamespaces ns = new XmlSerializerNamespaces();
//Add an empty namespace and empty value
ns.Add("", "");
//Create the serializer
XmlSerializer slz = new XmlSerializer(someType);
//Serialize the object with our own namespaces (notice the overload)
slz.Serialize(myXmlTextWriter, someObject, ns);
If by version you mean a tag or a release, then github provides download links for those. For example, if I want to install fetch version 0.3.2 (it is not available on npm), then I add to my package.json under dependencies:
"fetch": "https://github.com/github/fetch/archive/v0.3.2.tar.gz",
The only disadvantage when compared with the commit hash approach is that a hash is guaranteed not to represent changed code, whereas a tag could be replaced. Thankfully this rarely happens.
Update:
These days the approach I use is the compact notation for a GitHub served dependency:
"dependencies": {
"package": "github:username/package#commit"
}
Where commit can be anything commitish, like a tag. In the case of GitHub you can even drop the initial github: since it's the default.
The problem is in your playerMovement method. You are creating the string name of your room variables (ID1, ID2, ID3):
letsago = "ID" + str(self.dirDesc.values())
However, what you create is just a str. It is not the variable. Plus, I do not think it is doing what you think its doing:
>>>str({'a':1}.values())
'dict_values([1])'
If you REALLY needed to find the variable this way, you could use the eval function:
>>>foo = 'Hello World!'
>>>eval('foo')
'Hello World!'
or the globals function:
class Foo(object):
def __init__(self):
super(Foo, self).__init__()
def test(self, name):
print(globals()[name])
foo = Foo()
bar = 'Hello World!'
foo.text('bar')
However, instead I would strongly recommend you rethink you class(es). Your userInterface class is essentially a Room. It shouldn't handle player movement. This should be within another class, maybe GameManager or something like that.
This is totally OK.
m.group(0)) always captures the whole area that is covered by your regular expression. In this case, it's the whole string.(.*)(\\d+) (the first part of your regex) covers the ...QT300 int the first group and the 0 in the second.(.*) to (.*?).For more info on greedy vs. lazy, check this site.
Use
__DIR__
to get the current path of the script and this should fix your problem.
So:
require_once(__DIR__.'/../class/user.php');
This will prevent cases where you can run a PHP script from a different folder and therefore the relatives paths will not work.
Edit: slash problem fixed
This problem take with me more than 3 hours finally , I just tried the problem was in removing dot from the end just .
problem was
docker run -p 3000:80 --rm --name test-con test-app .
/usr/local/bin/docker-entrypoint.sh: 8: exec: .: Permission denied
just remove dot from the end of your command line :
docker run -p 3000:80 --rm --name test-con test-app
Please see below typescript for re-applying css class again to an element to override parent container (usually a framework component) css styles and force your custom styles. Your app framework (be it angular/react, probably does this so the parent container css was re-applied and none of your expected effects in css-class-name is showing up for your child element. Call this.overrideParentCssRule(childElement, 'css-class-name'); to do what the framework just did (call this in document.ready or end of event handler):
overrideParentCssRule(elem: HTMLElement, className: string) {
let cssRules = this.getCSSStyle(className);
for (let r: number = 0; r < cssRules.length; r++) {
let rule: CSSStyleRule = cssRules[r];
Object.keys(rule.style).forEach(s => {
if (isNaN(Number(s)) && rule.style[s]) {
elem.style[s] = rule.style[s];
}
});
}
}
You can also use common table expressions to store temporary datasets. They are more elegant and adhoc friendly:
WITH userData (name, oldlocation)
AS
(
SELECT name, location
FROM myTable INNER JOIN
otherTable ON ...
WHERE age>30
)
SELECT *
FROM userData -- you can also reuse the recordset in subqueries and joins
To complement ruslik's answer, in C++14 you can use this construction:
delete std::exchange(heapObject, nullptr);
Here I want to pad my number with 4 digit. For instance, if it is 1 then it should show as 0001, if it 11 it should show as 0011.
Below is the code that accomplishes this:
reciptno=1; // Pass only integer.
string formatted = string.Format("{0:0000}", reciptno);
TxtRecNo.Text = formatted; // Output=0001
I implemented this code to generate money receipt number for a PDF file.
Either use window.onload this way
<script>
window.onload = function() {
// ...
}
</script>
or alternatively
<script>
window.onload = functionName;
</script>
(yes, without the parentheses)
Or just put the script at the very bottom of page, right before </body>. At that point, all HTML DOM elements are ready to be accessed by document functions.
<body>
...
<script>
functionName();
</script>
</body>
