I know this may be kicking a dead horse, but maybe this can help someone. I have looked all over the place for a way to find my local IP address, but everywhere I find it says to use:
Dns.GetHostEntry(Dns.GetHostName());
I don't like this at all because it just gets all the addresses assigned to your computer. If you have multiple network interfaces (which pretty much all computers do now-a-days) you have no idea which address goes with which network interface. After doing a bunch of research I created a function to use the NetworkInterface class and yank the information out of it. This way I can tell what type of interface it is (Ethernet, wireless, loopback, tunnel, etc.), whether it is active or not, and SOOO much more.
public string GetLocalIPv4(NetworkInterfaceType _type)
{
string output = "";
foreach (NetworkInterface item in NetworkInterface.GetAllNetworkInterfaces())
{
if (item.NetworkInterfaceType == _type && item.OperationalStatus == OperationalStatus.Up)
{
foreach (UnicastIPAddressInformation ip in item.GetIPProperties().UnicastAddresses)
{
if (ip.Address.AddressFamily == AddressFamily.InterNetwork)
{
output = ip.Address.ToString();
}
}
}
}
return output;
}
Now to get the IPv4 address of your Ethernet network interface call:
GetLocalIPv4(NetworkInterfaceType.Ethernet);
Or your Wireless interface:
GetLocalIPv4(NetworkInterfaceType.Wireless80211);
If you try to get an IPv4 address for a wireless interface, but your computer doesn't have a wireless card installed it will just return an empty string. Same thing with the Ethernet interface.
Hope this helps someone! :-)
EDIT:
It was pointed out (thanks @NasBanov) that even though this function goes about extracting the IP address in a much better way than using Dns.GetHostEntry(Dns.GetHostName())
it doesn't do very well at supporting multiple interfaces of the same type or multiple IP addresses on a single interface. It will only return a single IP address when there may be multiple addresses assigned. To return ALL of these assigned addresses you could simply manipulate the original function to always return an array instead of a single string. For example:
public static string[] GetAllLocalIPv4(NetworkInterfaceType _type)
{
List<string> ipAddrList = new List<string>();
foreach (NetworkInterface item in NetworkInterface.GetAllNetworkInterfaces())
{
if (item.NetworkInterfaceType == _type && item.OperationalStatus == OperationalStatus.Up)
{
foreach (UnicastIPAddressInformation ip in item.GetIPProperties().UnicastAddresses)
{
if (ip.Address.AddressFamily == AddressFamily.InterNetwork)
{
ipAddrList.Add(ip.Address.ToString());
}
}
}
}
return ipAddrList.ToArray();
}
Now this function will return ALL assigned addresses for a specific interface type. Now to get just a single string, you could use the .FirstOrDefault()
extension to return the first item in the array or, if it's empty, return an empty string.
GetLocalIPv4(NetworkInterfaceType.Ethernet).FirstOrDefault();
I wouldn't use just FILENAME_H but
#ifndef FILENAME_H_AF06570D_B36E_4B82_8F97_C456AF4A38FD
#define FILENAME_H_AF06570D_B36E_4B82_8F97_C456AF4A38FD
//code stuff
#endif // FILENAME_H_AF06570D_B36E_4B82_8F97_C456AF4A38FD
I have always used a postfix guid. I came across a very poor code base some years ago that had different header files with the same file name and include guard. The files in question had defined a class with the same name. If only namespaces were used. Some projects compiled some didn't. Using unique guards was a part of the solution in differentiating headers and their contents.
On Windows with Visual Studio use guidgen.exe, on Linux uuidgen -t.
If you want to avoid using DNS:
List<IPAddress> ipList = new List<IPAddress>();
foreach (var netInterface in NetworkInterface.GetAllNetworkInterfaces())
{
foreach (var address in netInterface.GetIPProperties().UnicastAddresses)
{
if (address.Address.AddressFamily == AddressFamily.InterNetwork)
{
Console.WriteLine("found IP " + address.Address.ToString());
ipList.Add(address.Address);
}
}
}
To find all local IPv4 addresses:
IPAddress[] ipv4Addresses = Array.FindAll(
Dns.GetHostEntry(string.Empty).AddressList,
a => a.AddressFamily == AddressFamily.InterNetwork);
or use Array.Find
or Array.FindLast
if you just want one.
Since the inputs are empty and therefore invalid when instantiated, Angular correctly adds the ng-invalid
class.
A CSS rule you might try:
input.ng-dirty.ng-invalid {
color: red
}
Which basically states when the field has had something entered into it at some point since the page loaded and wasn't reset to pristine by $scope.formName.setPristine(true)
and something wasn't yet entered and it's invalid then the text turns red
.
Other useful classes for Angular forms (see input for future reference )
ng-valid-maxlength
- when ng-maxlength
passes
ng-valid-minlength
- when ng-minlength
passes
ng-valid-pattern
- when ng-pattern
passes
ng-dirty
- when the form has had something entered since the form loaded
ng-pristine
- when the form input has had nothing inserted since loaded (or it was reset via setPristine(true)
on the form)
ng-invalid
- when any validation fails (required
, minlength
, custom ones, etc)
Likewise there is also ng-invalid-<name>
for all these patterns and any custom ones created.
This answer missed one aspect: the OP asked for ALL combinations... not just combinations of length "r".
So you'd either have to loop through all lengths "L":
import itertools
stuff = [1, 2, 3]
for L in range(0, len(stuff)+1):
for subset in itertools.combinations(stuff, L):
print(subset)
Or -- if you want to get snazzy (or bend the brain of whoever reads your code after you) -- you can generate the chain of "combinations()" generators, and iterate through that:
from itertools import chain, combinations
def all_subsets(ss):
return chain(*map(lambda x: combinations(ss, x), range(0, len(ss)+1)))
for subset in all_subsets(stuff):
print(subset)
I had a similar issue and based on above suggestions I first added "super.setIntegerProperty("loadUrlTimeoutValue", 70000);" but that did not help. So I tried Project -> Clean, that worked and I can launch the app now !

If the date is given in a fixed form, you can simply use a regular expression to extract the date and "datetime.datetime.strptime" to parse the date:
import re
from datetime import datetime
match = re.search(r'\d{4}-\d{2}-\d{2}', text)
date = datetime.strptime(match.group(), '%Y-%m-%d').date()
Otherwise, if the date is given in an arbitrary form, you can't extract it easily.
UPDATE Feb. 2021
As in Activity v1.2.0 and Fragment v1.3.0, the new Activity Result APIs
have been introduced.
The Activity Result APIs provide components for registering for a result, launching the result, and handling the result once it is dispatched by the system.
So there is no need of using startActivityForResult
and onActivityResult
anymore.
In order to use the new API, you need to create an ActivityResultLauncher in your origin Activity, specifying the callback that will be run when the destination Activity finishes and returns the desired data:
private val intentLauncher =
registerForActivityResult(ActivityResultContracts.StartActivityForResult()) { result ->
if (result.resultCode == Activity.RESULT_OK) {
result.data?.getStringExtra("streetkey")
result.data?.getStringExtra("citykey")
result.data?.getStringExtra("homekey")
}
}
and then, launching your intent whenever you need to:
intentLauncher.launch(Intent(this, YourActivity::class.java))
And to return data from the destination Activity, you just have to add an intent with the values to return to the setResult()
method:
val data = Intent()
data.putExtra("streetkey", "streetname")
data.putExtra("citykey", "cityname")
data.putExtra("homekey", "homename")
setResult(Activity.RESULT_OK, data)
finish()

I had the same issue on a Windows 10 PC. I copied the project from my old computer to the new one, both 64 bits, and I installed the Oracle Client 64 bit on the new machine. I got the same error message, but after trying many solutions to no effect, what actually worked for me was this: In your Visual Studio (mine is 2017) go to Tools > Options > Projects and Solutions > Web Projects
On that page, check the option that says: Use the 64 bit version of IIS Express for Websites and Projects
I got the color range to be asymmetric simply by changing the symkey argument to FALSE
symm=F,symkey=F,symbreaks=T, scale="none"
Solved the color issue with colorRampPalette with the breaks argument to specify the range of each color, e.g.
colors = c(seq(-3,-2,length=100),seq(-2,0.5,length=100),seq(0.5,6,length=100))
my_palette <- colorRampPalette(c("red", "black", "green"))(n = 299)
Altogether
heatmap.2(as.matrix(SeqCountTable), col=my_palette,
breaks=colors, density.info="none", trace="none",
dendrogram=c("row"), symm=F,symkey=F,symbreaks=T, scale="none")
By default Chrome extensions do not run in Incognito mode. You have to explicitly enable the extension to run in Incognito.
It changes the rules for override priority of css cascades. See the CSS2 spec.
I've got one more additional option to get value by id
:
var idElement = document.getElementById("idName");
var selectedValue = idElement.options[idElement.selectedIndex].value;
It's a simple JavaScript
solution.
There are already answers which describes about window.location.href property and window.open() method.
I will go by Objective use:
Use window.location.href. Set href property to the href of another page.
Use window.open(). Pass parameters as per your goal.
Use window.location.href. Get value of window.location.href property. You can also get specific protocol, hostname, hashstring from window.location object.
See Location Object for more information.
You should just use something like:
YourModel.update_all(
ActiveRecord::Base.send(:sanitize_sql_for_assignment, {:value => "'wow'"})
)
That would do the trick. Using the ActiveRecord::Base#send method to invoke the sanitize_sql_for_assignment makes the Ruby (at least the 1.8.7 version) skip the fact that the sanitize_sql_for_assignment is actually a protected method.
You can get that error if you have an object with the same name as the schema. For example:
create sequence s2;
begin
s2.a;
end;
/
ORA-06550: line 2, column 6:
PLS-00302: component 'A' must be declared
ORA-06550: line 2, column 3:
PL/SQL: Statement ignored
When you refer to S2.MY_FUNC2
the object name is being resolved so it doesn't try to evaluate S2 as a schema name. When you just call it as MY_FUNC2
there is no confusion, so it works.
The documentation explains name resolution. The first piece of the qualified object name - S2 here - is evaluated as an object on the current schema before it is evaluated as a different schema.
It might not be a sequence; other objects can cause the same error. You can check for the existence of objects with the same name by querying the data dictionary.
select owner, object_type, object_name
from all_objects
where object_name = 'S2';
While some of the other answers have covered the simple cases using setjmp
and longjmp
, in a real application there's two concerns that really matter.
jmp_buf
will make these not work.jmp_buf
will cause all kinds of pain in this situation.The solution to these is to maintain a thread-local stack of jmp_buf
that get updated as you go. (I think this is what lua uses internally).
So instead of this (from JaredPar's awesome answer)
static jmp_buf s_jumpBuffer;
void Example() {
if (setjmp(s_jumpBuffer)) {
// The longjmp was executed and returned control here
printf("Exception happened\n");
} else {
// Normal code execution starts here
Test();
}
}
void Test() {
// Rough equivalent of `throw`
longjump(s_jumpBuffer, 42);
}
You'd use something like:
#define MAX_EXCEPTION_DEPTH 10;
struct exception_state {
jmp_buf s_jumpBuffer[MAX_EXCEPTION_DEPTH];
int current_depth;
};
int try_point(struct exception_state * state) {
if(current_depth==MAX_EXCEPTION_DEPTH) {
abort();
}
int ok = setjmp(state->jumpBuffer[state->current_depth]);
if(ok) {
state->current_depth++;
} else {
//We've had an exception update the stack.
state->current_depth--;
}
return ok;
}
void throw_exception(struct exception_state * state) {
longjump(state->current_depth-1,1);
}
void catch_point(struct exception_state * state) {
state->current_depth--;
}
void end_try_point(struct exception_state * state) {
state->current_depth--;
}
__thread struct exception_state g_exception_state;
void Example() {
if (try_point(&g_exception_state)) {
catch_point(&g_exception_state);
printf("Exception happened\n");
} else {
// Normal code execution starts here
Test();
end_try_point(&g_exception_state);
}
}
void Test() {
// Rough equivalent of `throw`
throw_exception(g_exception_state);
}
Again a more realistic version of this would include some way to store error information into the exception_state
, better handling of MAX_EXCEPTION_DEPTH
(maybe using realloc to grow the buffer, or something like that).
DISCLAIMER: The above code was written without any testing whatsoever. It is purely so you get an idea of how to structure things. Different systems and different compilers will need to implement the thread local storage differently. The code probably contains both compile errors and logic errors - so while you're free to use it as you choose, TEST it before using it ;)

I would suggest doing this in a more functional style :P
function CreateMessageboard(BoardMessages) {
var htmlMessageboardString = BoardMessages
.map(function(BoardMessage) {
return MessageToHTMLString(BoardMessage);
})
.join('');
}
Try this
This can be achieved as follows:
this.itemArr = this.itemArr.filter( h => h.id !== ID);
The behavior of host objects <object>
is due to ECMA262 implementation dependent and set attribute by setAttribute()
method may fail.
I see two solutions:
soft: element.data = "http://www.google.com";
hard: remove object from DOM tree and create new one with changed data attribute.
You either need to use first()
or get()
to fetch the results :
$userRecord = $this->where('email', $email)->where('password', $password)->first();
You most likely need to use first()
as you want only one result returned.
If the record isn't found null
will be returned. If you are building this query from inside an Eloquent class you could use self
.
for example :
$userRecord = self::where('email', $email)->where('password', $password)->first();
More info here
Correct answer is:
select table_record_id,
group_concat(if(value_name='note', value_text, NULL)) as note
,group_concat(if(value_name='hire_date', value_text, NULL)) as hire_date
,group_concat(if(value_name='termination_date', value_text, NULL)) as termination_date
,group_concat(if(value_name='department', value_text, NULL)) as department
,group_concat(if(value_name='reporting_to', value_text, NULL)) as reporting_to
,group_concat(if(value_name='shift_start_time', value_text, NULL)) as shift_start_time
,group_concat(if(value_name='shift_end_time', value_text, NULL)) as shift_end_time
from other_value
where table_name = 'employee'
and is_active = 'y'
and is_deleted = 'n'
GROUP BY table_record_id
Not sure what you are really after but if you want to print exactly what you have you can do:
Option 1
print(df['Item'].to_csv(index=False))
Sweet
Candy
Chocolate
Option 2
for v in df['Item']:
print(v)
Sweet
Candy
Chocolate
if you'd like to avoid numeric indices, you can use
a <- setdiff(names(a),c("name1", ..., "namen"))
to delete names namea...namen
from a. this works for lists
> l <- list(a=1,b=2)
> l[setdiff(names(l),"a")]
$b
[1] 2
as well as for vectors
> v <- c(a=1,b=2)
> v[setdiff(names(v),"a")]
b
2
you can also use VSCommands 2010 to run as different user:
template <typename C>
struct reverse_wrapper {
C & c_;
reverse_wrapper(C & c) : c_(c) {}
typename C::reverse_iterator begin() {return c_.rbegin();}
typename C::reverse_iterator end() {return c_.rend(); }
};
template <typename C, size_t N>
struct reverse_wrapper< C[N] >{
C (&c_)[N];
reverse_wrapper( C(&c)[N] ) : c_(c) {}
typename std::reverse_iterator<const C *> begin() { return std::rbegin(c_); }
typename std::reverse_iterator<const C *> end() { return std::rend(c_); }
};
template <typename C>
reverse_wrapper<C> r_wrap(C & c) {
return reverse_wrapper<C>(c);
}
eg:
int main(int argc, const char * argv[]) {
std::vector<int> arr{1, 2, 3, 4, 5};
int arr1[] = {1, 2, 3, 4, 5};
for (auto i : r_wrap(arr)) {
printf("%d ", i);
}
printf("\n");
for (auto i : r_wrap(arr1)) {
printf("%d ", i);
}
printf("\n");
return 0;
}
Best way to create SharedPreference
and for global usage you need to create a class like below:
public class PreferenceHelperDemo {
private final SharedPreferences mPrefs;
public PreferenceHelperDemo(Context context) {
mPrefs = PreferenceManager.getDefaultSharedPreferences(context);
}
private String PREF_Key= "Key";
public String getKey() {
String str = mPrefs.getString(PREF_Key, "");
return str;
}
public void setKey(String pREF_Key) {
Editor mEditor = mPrefs.edit();
mEditor.putString(PREF_Key, pREF_Key);
mEditor.apply();
}
}
The previous answers all state that you can do the following:
var d = eval(net_datetime.slice(1, -1));
However, this doesn't work in either Chrome or FF because what's getting evaluated literally is:
// returns the current timestamp instead of the specified epoch timestamp
var d = Date([epoch timestamp]);
The correct way to do this is:
var d = eval("new " + net_datetime.slice(1, -1)); // which parses to
var d = new Date([epoch timestamp]);
paint.setStrokeWidth(3);
paint.setColor(BLACK);
and either one of your drawRect
should work.

Note that usage of a SerialPort.DataReceived
event is optional. You can set proper timeout using SerialPort.ReadTimeout
and continuously call SerialPort.Read()
after you wrote something to a port until you get a full response.
Moreover you can use SerialPort.BaseStream
property to extract an underlying Stream
instance. The benefit of using a Stream
is that you can easily utilize various decorators with it:
var port = new SerialPort();
// LoggingStream inherits Stream, implements IDisposable, needen abstract methods and
// overrides needen virtual methods.
Stream portStream = new LoggingStream(port.BaseStream);
portStream.Write(...); // Logs write buffer.
portStream.Read(...); // Logs read buffer.

You want to put code in the master page code behind that inserts HTML into the contents of a page that is using that master page?
I would not search for the control via FindControl as this is a fragile solution that could easily be broken if the name of the control changed.
Your best bet is to declare an event in the master page that any child page could handle. The event could pass the HTML as an EventArg.
You have to do it inline. But you really don't need that swap in Java.
Example code:
class inside:
def __init__(self):
self.l = []
def insert(self, element):
self.l.append(element)
class outside:
l = [] # static variable - the same for all instances
def insert(self, element):
self.l.append(element)
def main():
x = inside()
x.insert(8)
print(x.l) # [8]
y = inside()
print(y.l) # []
# ----------------------------
x = outside()
x.insert(8)
print(x.l) # [8]
y = outside()
print(y.l) # [8] # here is the difference
if __name__ == '__main__':
main()
you can reduce the legend size setting:
plt.legend(labelspacing=y, handletextpad=x,fontsize)
labelspacing is the vertical space between each label.
handletextpad is the distance between the actual legend and your label.
And fontsize is self-explanatory
Just like leonbloy suggested, using two schemas in a database is the way to go. Suppose a source schema (old DB) and a target schema (new DB), you can try something like this (you should consider column names, types, etc.):
INSERT INTO target.Awards SELECT * FROM source.Nominations;
Here's a nice function that allows this:
public static void animateBetweenColors(final @NonNull View viewToAnimateItsBackground, final int colorFrom,
final int colorTo, final int durationInMs) {
final ColorDrawable colorDrawable = new ColorDrawable(durationInMs > 0 ? colorFrom : colorTo);
ViewCompat.setBackground(viewToAnimateItsBackground, colorDrawable);
if (durationInMs > 0) {
final ValueAnimator colorAnimation = ValueAnimator.ofObject(new ArgbEvaluator(), colorFrom, colorTo);
colorAnimation.addUpdateListener(animator -> {
colorDrawable.setColor((Integer) animator.getAnimatedValue());
ViewCompat.setBackground(viewToAnimateItsBackground, colorDrawable);
});
colorAnimation.setDuration(durationInMs);
colorAnimation.start();
}
}
And in Kotlin:
@JvmStatic
fun animateBetweenColors(viewToAnimateItsBackground: View, colorFrom: Int, colorTo: Int, durationInMs: Int) {
val colorDrawable = ColorDrawable(if (durationInMs > 0) colorFrom else colorTo)
ViewCompat.setBackground(viewToAnimateItsBackground, colorDrawable)
if (durationInMs > 0) {
val colorAnimation = ValueAnimator.ofObject(ArgbEvaluator(), colorFrom, colorTo)
colorAnimation.addUpdateListener { animator: ValueAnimator ->
colorDrawable.color = (animator.animatedValue as Int)
ViewCompat.setBackground(viewToAnimateItsBackground, colorDrawable)
}
colorAnimation.duration = durationInMs.toLong()
colorAnimation.start()
}
}
Try this, replacing .myClassName
with the actual name of the class (but keep the period at the beginning).
$('.myClassName').each(function() {
alert( this.id );
});
So if the class is "test", you'd do $('.test').each(func...
.
This is the specific form of .each()
that iterates over a jQuery object.
The form you were using iterates over any type of collection. So you were essentially iterating over an array of characters t,e,s,t
.
Using that form of $.each()
, you would need to do it like this:
$.each($('.myClassName'), function() {
alert( this.id );
});
...which will have the same result as the example above.
Colin's example for me clashed with the like button. So I adapted it to only target the Like Box.
.fb-like-box, .fb-like-box span, .fb-like-box span iframe[style] { width: 100% !important; }
Tested in most modern browsers.
Here's an example:
I'm writing a C# program that interfaces with a high-speed camera. The camera has its own driver that acquires images and loads them into the computer's memory for me automatically.
So when I'm ready to bring the latest image into my program to work with, the camera driver provides me with an IntPtr to where the image is ALREADY stored in physical memory, so I don't have to waste time/resources creating another block of memory to store an image that's in memory already. The IntPtr just shows me where the image already is.
If each file only has one sequence of aminoacids, I wouldn't use regular expressions at all. Just something like this:
def read_amino_acid_sequence(path):
with open(path) as sequence_file:
title = sequence_file.readline() # read 1st line
aminoacid_sequence = sequence_file.read() # read the rest
# some cleanup, if necessary
title = title.strip() # remove trailing white spaces and newline
aminoacid_sequence = aminoacid_sequence.replace(" ","").replace("\n","")
return title, aminoacid_sequence
int value = 1;
string description = Enumerations.GetEnumDescription((MyEnum)value);
The default underlying data type for an enum
in C# is an int
, you can just cast it.
Not directly answering your question but something to remember:
When using includes with allow_url_include on in your ini beware that, when accessing sessions from included files, if from a script you include one file using an absolute file reference and then include a second file from on your local server using a url file reference that they have different variable scope and the same session will not be seen from both included files. The original session won't be seen from the url included file.

In line 2, there's a std::string
involved (name
). There are operations defined for char[] + std::string
, std::string + char[]
, etc. "Hello " + name
gives a std::string
, which is added to " you are "
, giving another string, etc.
In line 3, you're saying
char[] + char[] + char[]
and you can't just add arrays to each other.
I've also noticed that the question was "answered" some time ago but I don't understand the stories that say you can't open a utf8-encoded csv file successfully in Excel without using the text wizard.
My reproducible experience:
Type Old MacDonald had a farm,ÈÌÉÍØ
into Notepad, hit Enter, then Save As (using the UTF-8 option).
Using Python to show what's actually in there:
>>> open('oldmac.csv', 'rb').read()
'\xef\xbb\xbfOld MacDonald had a farm,\xc3\x88\xc3\x8c\xc3\x89\xc3\x8d\xc3\x98\r\n'
>>> ^Z
Good. Notepad has put a BOM at the front.
Now go into Windows Explorer, double click on the file name, or right click and use "Open with ...", and up pops Excel (2003) with display as expected.
In bash version 3 you can use the '=~' operator:
if [[ "$date" =~ ^[0-9]{8}$ ]]; then
echo "Valid date"
else
echo "Invalid date"

Just use cd /d %root%
to switch driver letters and change directories.
Alternatively, use pushd %root%
to switch drive letters when changing directories as well as storing the previous directory on a stack so you can use popd
to switch back.
Note that pushd
will also allow you to change directories to a network share. It will actually map a network drive for you, then unmap it when you execute the popd
for that directory.
If your CString is Unicode, you'll need to do a conversion to multi-byte characters. Fortunately there is a version of CString which will do this automatically.
CString unicodestr = _T("Testing");
CStringA charstr(unicodestr);
DoMyStuff((const char *) charstr);
Comparision of Agile to Scrum is similar to comparision of organism to one organ.
Scrum suggests the way of management while it doesn't prescribe everything what is necessary to do to be able to react fast on changes. Only by adding other agile techniques like continuous integration, extreme programming, test driven development your teams will be able to deliver products not just fast, but also product that customer wants with great quality.
The first way is "more correct", what intention could there be to express? If the code ends, it ends. That's pretty clear, in my opinion.
I don't understand what could possibly be confusing and need clarification. If there's no looping construct being used, then what could possibly happen other than that the function stops executing?
I would be severly annoyed by such a pointless extra return
statement at the end of a void
function, since it clearly serves no purpose and just makes me feel the original programmer said "I was confused about this, and now you can be too!" which is not very nice.
If you want to see the array as an array, you can say
alert(JSON.stringify(aCustomers));
instead of all those document.write
s.
However, if you want to display them cleanly, one per line, in your popup, do this:
alert(aCustomers.join("\n"));
2014 and above at least you can set a default and it will take that and NOT error when you do not pass that parameter. Partial Example: the 3rd parameter is added as optional. exec of the actual procedure with only the first two parameters worked fine
exec getlist 47,1,0
create procedure getlist
@convId int,
@SortOrder int,
@contestantsOnly bit = 0

Make sure the process (account) that the site is running under has privileges to write to the output directory.
In IIS 7 and above this is configured on the application pool and is normally the AppPool Identity, which will not normally have permission to write to all directories.
Check your event logs (application and security) to see if any exceptions were thrown.
The full example explaining the syntax referenced by Robin... brought it home for me:
Something like the following works fine:
function foo<T>(x: T): T { return x; }
However using an arrow generic function will not:
const foo = <T>(x: T) => x; // ERROR : unclosed `T` tag
Workaround: Use extends on the generic parameter to hint the compiler that it's a generic, e.g.:
const foo = <T extends unknown>(x: T) => x;
string clearText = txtPassword.Text;
string EncryptionKey = "MAKV2SPBNI99212";
byte[] clearBytes = Encoding.Unicode.GetBytes(clearText);
using (Aes encryptor = Aes.Create())
{
Rfc2898DeriveBytes pdb = new Rfc2898DeriveBytes(EncryptionKey, new byte[] { 0x49, 0x76, 0x61, 0x6e, 0x20, 0x4d, 0x65, 0x64, 0x76, 0x65, 0x64, 0x65, 0x76 });
encryptor.Key = pdb.GetBytes(32);
encryptor.IV = pdb.GetBytes(16);
using (MemoryStream ms = new MemoryStream())
{
using (CryptoStream cs = new CryptoStream(ms, encryptor.CreateEncryptor(), CryptoStreamMode.Write))
{
cs.Write(clearBytes, 0, clearBytes.Length);
cs.Close();
}
clearText = Convert.ToBase64String(ms.ToArray());
}
}
Console.WriteLine(decimal.Round(pay,2));
For external url you have to use "http://www.yahoo.com" as the redirect url.
This is explained in the redirect: prefix of Spring reference documentation.
redirect:/myapp/some/resource
will redirect relative to the current Servlet context, while a name such as
will redirect to an absolute URL
Here is a script to show differences between files in two folders. It works recursively. Change dir1 and dir2.
(search() { for i in $1/*; do [ -f "$i" ] && (diff "$1/${i##*/}" "$2/${i##*/}" || echo "files: $1/${i##*/} $2/${i##*/}"); [ -d "$i" ] && search "$1/${i##*/}" "$2/${i##*/}"; done }; search "dir1" "dir2" )
With JUnit 4.12 the following didn't work for me:
java -cp .:/usr/share/java/junit.jar org.junit.runner.JUnitCore [test class name]
Apparently, from JUnit 4.11 onwards you should also include hamcrest-core.jar
in your classpath:
java -cp .:/usr/share/java/junit.jar:/usr/share/java/hamcrest-core.jar org.junit.runner.JUnitCore [test class name]
Try using this tool,which is just a simple js script https://github.com/shashwatsahai/CSSExtractor/ This tool helps in getting the CSS from a specific page listing all sources for active styles and save it to a JSON with source as key and rules as value. It loads all the CSS from the href links and tells all the styles applied from them You can modify the code to save all css into a .css file. Thereby combining all your css.
there is no way to specifically target an element with php, you can either embed the php code between a div tag or use jquery which would be longer.
You can use "group by" + "orderby". See LINQ 101 for details
var list = new List<string> {"a", "b", "a", "c", "a", "b"};
var q = from x in list
group x by x into g
let count = g.Count()
orderby count descending
select new {Value = g.Key, Count = count};
foreach (var x in q)
{
Console.WriteLine("Value: " + x.Value + " Count: " + x.Count);
}
In response to this post (now deleted):
If you have a list of some custom objects then you need to use custom comparer or group by specific property.
Also query can't display result. Show us complete code to get a better help.
Based on your latest update:
You have this line of code:
group xx by xx into g
Since xx is a custom object system doesn't know how to compare one item against another. As I already wrote, you need to guide compiler and provide some property that will be used in objects comparison or provide custom comparer. Here is an example:
Note that I use Foo.Name as a key - i.e. objects will be grouped based on value of Name property.
There is one catch - you treat 2 objects to be duplicate based on their names, but what about Id ? In my example I just take Id of the first object in a group. If your objects have different Ids it can be a problem.
//Using extension methods
var q = list.GroupBy(x => x.Name)
.Select(x => new {Count = x.Count(),
Name = x.Key,
ID = x.First().ID})
.OrderByDescending(x => x.Count);
//Using LINQ
var q = from x in list
group x by x.Name into g
let count = g.Count()
orderby count descending
select new {Name = g.Key, Count = count, ID = g.First().ID};
foreach (var x in q)
{
Console.WriteLine("Count: " + x.Count + " Name: " + x.Name + " ID: " + x.ID);
}

Should do it. Assuming you don't need it to flow.
If you're creating a program that doesn't require user input you could always just create it as a service. A service won't show any kind of UI.
The return false is saying not to take the default action, which in the case of an <a href>
is to follow the link. When you return false to the onclick, then the href will be ignored.
If your latest commit is on the master branch, you can simply use
git checkout master
Non bare repository allows you to (into your working tree) capture changes by creating new commits.
Bare repositories are only changed by transporting changes from other repositories.
use <meta http-equiv="X-Frame-Options" content="allow">
in the one to show in the iframe to allow it.
try it it is working fine
<%:Html.ActionLink("Details","Details","Product", new {id=item.dateID },null)%>
It's not fully cross-browsers solution, but must work well in most modern browser.

NOTES
RESOURCES:
sysexits.h has a list of standard exit codes. It seems to date back to at least 1993 and some big projects like Postfix use it, so I imagine it's the way to go.
From the OpenBSD man page:
According to style(9), it is not good practice to call exit(3) with arbi- trary values to indicate a failure condition when ending a program. In- stead, the pre-defined exit codes from sysexits should be used, so the caller of the process can get a rough estimation about the failure class without looking up the source code.
I'm assuming cross-domain iFrame since presumably the risk would be lower if you controlled it yourself.
You might want to use helper library like http://momentjs.com/ which wraps the native javascript date object for easier manipulations
Then you can do things like:
var day = moment("12-25-1995", "MM-DD-YYYY");
or
var day = moment("25/12/1995", "DD/MM/YYYY");
then operate on the date
day.add('days', 7)
and to get the native javascript date
day.toDate();
I also had the same problem, I tried many different command lines, this one worked for me:
Try:
conda install py-xgboost

Here's an example that shows how table(.)
(or, more closely matching your desired output, data.frame(table(.))
does what it sounds like you are asking for.
Note also how to share reproducible sample data in a way that others can copy and paste into their session.
Here's the (reproducible) sample data:
mydf <- structure(list(ID = c(110L, 111L, 121L, 131L, 141L),
MONTH.YEAR = c("JAN. 2012", "JAN. 2012",
"FEB. 2012", "FEB. 2012",
"MAR. 2012"),
VALUE = c(1000L, 2000L, 3000L, 4000L, 5000L)),
.Names = c("ID", "MONTH.YEAR", "VALUE"),
class = "data.frame", row.names = c(NA, -5L))
mydf
# ID MONTH.YEAR VALUE
# 1 110 JAN. 2012 1000
# 2 111 JAN. 2012 2000
# 3 121 FEB. 2012 3000
# 4 131 FEB. 2012 4000
# 5 141 MAR. 2012 5000
Here's the calculation of the number of rows per group, in two output display formats:
table(mydf$MONTH.YEAR)
#
# FEB. 2012 JAN. 2012 MAR. 2012
# 2 2 1
data.frame(table(mydf$MONTH.YEAR))
# Var1 Freq
# 1 FEB. 2012 2
# 2 JAN. 2012 2
# 3 MAR. 2012 1
var demoArray = ['A','B','C','D'];
var ArrayIndexValue = 2;
if(ArrayIndexValue in demoArray){
//Array index exists
}else{
//Array Index does not Exists
}
Also, you can use -o
or --offline
in the mvn command line which will put maven in "offline mode" so it won't check for updates. You'll get some warning about not being able to get dependencies not already in your local repo, but no big deal.

Step #2
Add -

Info on MySQL's full text search. This is restricted to MyISAM tables, so may not be suitable if you wantto use a different table type.
http://dev.mysql.com/doc/refman/5.0/en/fulltext-search.html
Even if WHERE textcolumn LIKE "%SUBSTRING%"
is going to be slow, I think it is probably better to let the Database handle it rather than have PHP handle it. If it is possible to restrict searches by some other criteria (date range, user, etc) then you may find the substring search is OK (ish).
If you are searching for whole words, you could pull out all the individual words into a separate table and use that to restrict the substring search. (So when searching for "my search string" you look for the the longest word "search" only do the substring search on records containing the word "search")

just to add some clarity, you need to stage changes with git add
, then amend last commit:
git add /path/to/modified/files
git commit --amend --no-edit
This is especially useful for if you forgot to add some changes in last commit or when you want to add more changes without creating new commits by reusing the last commit.
in my case it was the path lenght (incl. file name).
..\..\..\..\..\..\..\SWX\Binary\VS2008\Output\Win32\Debug\boost_unit_test_framework-vc90-mt-gd-1_57.lib;
as for the release the path was (this has worked correctly):
..\..\..\..\..\..\..\SWX\Binary\VS2008\Output\Win32\Release\boost_unit_test_framework-vc90-mt-1_57.lib;
==> one char shorter.
Linker -> input -> additoinal dependencies
so the problem for me was the total size of the path + filename string was too long!

and then activated using source venv/bin/actiave
. which python

both pointed towards the correct binaries in the virtualenv, however I was not able to install to the virtualenv, even when using the full path of the binaries. Turned out that when I uninstalled the python-pip package with sudo pacman -R python-pip python-reportlab
(had to include reportlab to satisfy dependencies) everything started to work as expected. Not sure why, but this is probably due to a double install where the system package is taking precedence.

using a table variable which contains passed in namesThe main reason why you see that error is nltk couldn't find punkt
package. Due to the size of nltk
suite, all available packages are not downloaded by default when one installs it.
You can download punkt
package like this.

@media only screen and (min-width: 200px) and (max-width: 767px) and (orientation : portrait) {
//Put your CSS here for 200px to 767px width devices (cover all mobile portrait width //
}
When using Windows.Web.Http namespace, for POST instead of FormUrlEncodedContent we write HttpFormUrlEncodedContent. Also the response is type of HttpResponseMessage. The rest is as Evan Mulawski wrote down.
The issue here is that ng-repeat
creates its own scope, so when you do selected=$index
it creates a new a selected
property in that scope rather than altering the existing one. To fix this you have two options:
Change the selected property to a non-primitive (ie object or array, which makes javascript look up the prototype chain) then set a value on that:
$scope.selected = {value: 0};
<a ng-click="selected.value = $index">A{{$index}}</a>
or
Use the $parent
variable to access the correct property. Though less recommended as it increases coupling between scopes
<a ng-click="$parent.selected = $index">A{{$index}}</a>
I would use
def example(arg1, arg2, arg3):
if arg1 == 1 and arg2 == 2 and arg3 == 3:
print("Example Text")
The and
operator is identical to the logic gate with the same name; it will return 1 if and only if all of the inputs are 1. You can also use or
operator if you want that logic gate.
EDIT: Actually, the code provided in your post works fine with me. I don't see any problems with that. I think that this might be a problem with your Python, not the actual language.
Generally if you are not sure of what value you will end up returning, you should consider using return-type as super-class of all the return values. In this case, where you need to return String or int, consider returning Object class(which is the base class of all the classes defined in java).
But be careful to have instanceof checks where you are calling this method. Or else you may end up getting ClassCastException.
public static void main(String args[]) {
Object obj = myMethod(); // i am calling static method from main() which return Object
if(obj instanceof String){
// Do something
}else(obj instance of Integer) {
//do something else
}
I'm using Rails 4.2.4 and couldn't work out why I was getting:
Can't verify CSRF token authenticity
I have in the layout:
<%= csrf_meta_tags %>
In the controller:
protect_from_forgery with: :exception
Invoking tcpdump -A -s 999 -i lo port 3000
was showing the header being set ( despite not needing to set the headers with ajaxSetup
- it was done already):
X-CSRF-Token: XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX
Content-Type: application/x-www-form-urlencoded; charset=UTF-8
X-Requested-With: XMLHttpRequest
DNT: 1
Content-Length: 125
authenticity_token=XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX
In the end it was failing because I had cookies switched off. CSRF doesn't work without cookies being enabled, so this is another possible cause if you're seeing this error.
These variables are constants, i.e. private static final
whether they're named in all caps or not. The all-caps convention simply makes it more obvious that these variables are meant to be constants, but it isn't required. I've seen
private static final Logger log = Logger.getLogger(MyClass.class);
in lowercase before, and I'm fine with it because I know to only use the logger to log messages, but it does violate the convention. You could argue that naming it log
is a sub-convention, I suppose. But in general, naming constants in uppercase isn't the One Right Way, but it is The Best Way.
The problem was caused by not setting the CUDA_VISIBLE_DEVICES
variable within the shell correctly.
To specify CUDA device 1
for example, you would set the CUDA_VISIBLE_DEVICES
using
export CUDA_VISIBLE_DEVICES=1
or
CUDA_VISIBLE_DEVICES=1 ./cuda_executable
The former sets the variable for the life of the current shell, the latter only for the lifespan of that particular executable invocation.
If you want to specify more than one device, use
export CUDA_VISIBLE_DEVICES=0,1
or
CUDA_VISIBLE_DEVICES=0,1 ./cuda_executable

Just to complete the answer (using the KeyEvent is the way to go) but up arrow is 38 and down arrow is 40 so:

Use boost::filesystem, that will give you a portable way of doing those kinds of things and abstract away all ugly details for you.
It'll have the same behavior as the underlying recv libc call see the man page for an official description of behavior (or read a more general description of the sockets api).
Here is what I do to avoid the issues of making the remote server accept your local external IP:
-L
to transfer the port 6006
of the remote server into the port 16006
of my machine (for instance):
ssh -L 16006:127.0.0.1:6006 olivier@my_server_ip
What it does is that everything on the port 6006
of the server (in 127.0.0.1:6006
) will be forwarded to my machine on the port 16006
.
tensorboard --logdir log
with the default 6006
portYou should avoid having two checkboxes with the same name if you plan to reference them like document.FC.c1
. If you have multiple checkboxes named c1
how will the browser know which you are referring to?
Here's a non-jQuery solution to check if any checkboxes on the page are checked.
var checkboxes = document.querySelectorAll('input[type="checkbox"]');
var checkedOne = Array.prototype.slice.call(checkboxes).some(x => x.checked);
You need the Array.prototype.slice.call
part to convert the NodeList
returned by document.querySelectorAll
into an array that you can call some
on.
dt.Rows[1].ItemArray
gives you a copy of item arrays. When you modify it, you're not modifying the original.
You can simply do this:
dt.Rows[1][3] = "Value";
ItemArray property is used when you want to modify all row values.
ex.:
dt.Rows[1].ItemArray = newItemArray;
What about using idate()? idate()
$integer = idate('w', $timestamp);
It is mostly syntactic sugar, but a couple differences are noteworthy:
ON is the more general of the two. One can join tables ON a column, a set of columns and even a condition. For example:
SELECT * FROM world.City JOIN world.Country ON (City.CountryCode = Country.Code) WHERE ...
USING is useful when both tables share a column of the exact same name on which they join. In this case, one may say:
SELECT ... FROM film JOIN film_actor USING (film_id) WHERE ...
An additional nice treat is that one does not need to fully qualify the joining columns:
SELECT film.title, film_id -- film_id is not prefixed
FROM film
JOIN film_actor USING (film_id)
WHERE ...
To illustrate, to do the above with ON, we would have to write:
SELECT film.title, film.film_id -- film.film_id is required here
FROM film
JOIN film_actor ON (film.film_id = film_actor.film_id)
WHERE ...
Notice the film.film_id
qualification in the SELECT
clause. It would be invalid to just say film_id
since that would make for an ambiguity:
ERROR 1052 (23000): Column 'film_id' in field list is ambiguous
As for select *
, the joining column appears in the result set twice with ON
while it appears only once with USING

I ran into the same problem with an "update"-statement. My solution was simply to run through the operations available in phpMyAdmin for the table. I optimized, flushed and defragmented the table (not in that order). No need to drop the table and restore it from backup for me. :)
This is an updated version for .NET 4.5 and newer using async/await and IEnumerables:
public static class CompressionExtensions
{
public static async Task<IEnumerable<byte>> Zip(this object obj)
{
byte[] bytes = obj.Serialize();
using (MemoryStream msi = new MemoryStream(bytes))
using (MemoryStream mso = new MemoryStream())
{
using (var gs = new GZipStream(mso, CompressionMode.Compress))
await msi.CopyToAsync(gs);
return mso.ToArray().AsEnumerable();
}
}
public static async Task<object> Unzip(this byte[] bytes)
{
using (MemoryStream msi = new MemoryStream(bytes))
using (MemoryStream mso = new MemoryStream())
{
using (var gs = new GZipStream(msi, CompressionMode.Decompress))
{
// Sync example:
//gs.CopyTo(mso);
// Async way (take care of using async keyword on the method definition)
await gs.CopyToAsync(mso);
}
return mso.ToArray().Deserialize();
}
}
}
public static class SerializerExtensions
{
public static byte[] Serialize<T>(this T objectToWrite)
{
using (MemoryStream stream = new MemoryStream())
{
BinaryFormatter binaryFormatter = new BinaryFormatter();
binaryFormatter.Serialize(stream, objectToWrite);
return stream.GetBuffer();
}
}
public static async Task<T> _Deserialize<T>(this byte[] arr)
{
using (MemoryStream stream = new MemoryStream())
{
BinaryFormatter binaryFormatter = new BinaryFormatter();
await stream.WriteAsync(arr, 0, arr.Length);
stream.Position = 0;
return (T)binaryFormatter.Deserialize(stream);
}
}
public static async Task<object> Deserialize(this byte[] arr)
{
object obj = await arr._Deserialize<object>();
return obj;
}
}
With this you can serialize everything BinaryFormatter
supports, instead only of strings.
Edit:
In case, you need take care of Encoding
, you could just use Convert.ToBase64String(byte[])...
Adding the actual code here for future reference
So, there are 3 steps, and therefore 3 SQL statements:
Step 1: Move the non duplicates (unique tuples) into a temporary table
CREATE TABLE new_table as
SELECT * FROM old_table WHERE 1 GROUP BY [column to remove duplicates by];
Step 2: delete the old table (or rename it) We no longer need the table with all the duplicate entries, so drop it!
DROP TABLE old_table;
Step 3: rename the new_table to the name of the old_table
RENAME TABLE new_table TO old_table;
And of course, don't forget to fix your buggy code to stop inserting duplicates!
using Apache IO could be another option for copy the Stream
@RequestMapping(path = "/file/{fileId}", method = RequestMethod.GET, produces = MediaType.APPLICATION_JSON_VALUE)
public ResponseEntity<?> downloadFile(@PathVariable(value="fileId") String fileId,HttpServletResponse response) throws Exception {
InputStream yourInputStream = ...
IOUtils.copy(yourInputStream, response.getOutputStream());
response.flushBuffer();
return ResponseEntity.ok().build();
}

The easiest way i tired in xcode 4.52 was to create an additional view and connect them by using segue modal(control drag the button from view one to the second view, chose Modal). Then drag in a button to second view or the modal view that you created. Control and drag this button to the header file and use action connection. This will create an IBaction in your controller.m file. Find your button action type in the code.

I don't think IE supports the use of auto for setting height / width, so you could try giving this a numeric value (like Jarett suggests).
Also, it doesn't look like you are clearing your floats properly. Try adding this to your CSS for #container:
#container {
height:100%;
width:100%;
overflow:hidden;
/* for IE */
zoom:1;
}
Using jQuery:
parent.html
<body>
<script type="text/javascript" src="https://code.jquery.com/jquery-2.1.4.min.js"></script>
<style>
iframe {
width: 100%;
border: 1px solid black;
}
</style>
<script>
function foo(w, h) {
$("iframe").css({width: w, height: h});
return true; // for debug purposes
}
</script>
<iframe src="child.html"></iframe>
</body>
child.html
<body>
<script type="text/javascript" src="https://code.jquery.com/jquery-2.1.4.min.js"></script>
<script>
$(function() {
var w = $("#container").css("width");
var h = $("#container").css("height");
var req = parent.foo(w, h);
console.log(req); // for debug purposes
});
</script>
<style>
body, html {
margin: 0;
}
#container {
width: 500px;
height: 500px;
background-color: red;
}
</style>
<div id="container"></div>
</body>
If you wanted to accomplish this with pure HTML alone, this solution will work across all major browsers:
Description Lists
Simply using the following HTML:

<dt>List Item 1</dt>
<dd>Sub-Item 1.1</dd>
<dt>List Item 2</dt>
<dd>Sub-Item 2.1</dd>
<dd>Sub-Item 2.2</dd>
<dd>Sub-Item 2.3</dd>
<dt>List Item 3</dt>
<dd>Sub-Item 3.1</dd>
</dl>

i have seen your running code .There is one line correction in your code.
Write:
$("#wrapper").rotate(angle);
instead of:
$("#image").rotate(angle);
and you will get your desired output,hope this is what you want.
A few of the above expressions and extended expressions did not work for me, but the regular expression "$\n$" did.
There is one fatal flaw in this otherwise great and helpful test: As memset is the first instruction, there seems to be some "memory overhead" or so which makes it extremely slow. Moving the timing of memset to second place and something else to first place or simply timing memset twice makes memset the fastest with all compile switches!!!
I saw jheriko's comment above and was initially agreeing that I couldn't find a way to avoid using DoEvents if you end up spinning your main UI thread waiting for a long running asynchronous piece of code on another thread to complete. But from Matthias's answer a simple Refresh of a small panel on my UI can replace the DoEvents (and avoid a nasty side effect).
More detail on my case ...
I was doing the following (as suggested here) to ensure that a progress bar type splash screen (How to display a "loading" overlay...) updated during a long running SQL command:
IAsyncResult asyncResult = sqlCmd.BeginExecuteNonQuery();
while (!asyncResult.IsCompleted) //UI thread needs to Wait for Async SQL command to return
{
System.Threading.Thread.Sleep(10);
Application.DoEvents(); //to make the UI responsive
}
The bad: For me calling DoEvents meant that mouse clicks were sometimes firing on forms behind my splash screen, even if I made it TopMost.
The good/answer: Replace the DoEvents line with a simple Refresh call to a small panel in the centre of my splash screen, FormSplash.Panel1.Refresh()
. The UI updates nicely and the DoEvents weirdness others have warned of was gone.
Simply write one line in the constructor:
setResizable(false);
This will make it impossible to resize the frame.
If you use jQuery then you can write the following code:
$("#selectId option:selected").html();
Could you use FILE*
instead, and the measure the performance you've gained?
A couple of options is to use fwrite/write
instead of fstream
:
#include <stdio.h>
int main ()
{
FILE * pFile;
char buffer[] = { 'x' , 'y' , 'z' };
pFile = fopen ( "myfile.bin" , "w+b" );
fwrite (buffer , 1 , sizeof(buffer) , pFile );
fclose (pFile);
return 0;
}
If you decide to use write
, try something similar:
#include <unistd.h>
#include <fcntl.h>
int main(void)
{
int filedesc = open("testfile.txt", O_WRONLY | O_APPEND);
if (filedesc < 0) {
return -1;
}
if (write(filedesc, "This will be output to testfile.txt\n", 36) != 36) {
write(2, "There was an error writing to testfile.txt\n", 43);
return -1;
}
return 0;
}
I would also advice you to look into memory map
. That may be your answer. Once I had to process a 20GB file in other to store it in the database, and the file as not even opening. So the solution as to utilize moemory map. I did that in Python
though.
If you have python installed you could try:
python -c 'import sys;f=open(sys.argv[1]);print len(f.readline().split("|"))' \
stores.dat
Following on from chimeric's answer above:
To get ALL the column indices in the df, so i used:
which(!names(df)%in%c())
or store in a list:
indexLst<-which(!names(df)%in%c())
The slickest method woud be to use LINQ:
var fileCount = (from file in Directory.EnumerateFiles(@"H:\iPod_Control\Music", "*.mp3", SearchOption.AllDirectories)
select file).Count();
In order to assign a variable safely you have to use the SET-SELECT statement:
SET @PrimaryContactKey = (SELECT c.PrimaryCntctKey
FROM tarcustomer c, tarinvoice i
WHERE i.custkey = c.custkey
AND i.invckey = @tmp_key)
Make sure you have both a starting and an ending parenthesis!
The reason the SET-SELECT version is the safest way to set a variable is twofold.
1. The SELECT returns several posts
What happens if the following select results in several posts?
SELECT @PrimaryContactKey = c.PrimaryCntctKey
FROM tarcustomer c, tarinvoice i
WHERE i.custkey = c.custkey
AND i.invckey = @tmp_key
@PrimaryContactKey
will be assigned the value from the last post in the result.
In fact @PrimaryContactKey
will be assigned one value per post in the result, so it will consequently contain the value of the last post the SELECT-command was processing.
Which post is "last" is determined by any clustered indexes or, if no clustered index is used or the primary key is clustered, the "last" post will be the most recently added post. This behavior could, in a worst case scenario, be altered every time the indexing of the table is changed.
With a SET-SELECT statement your variable will be set to null
.
2. The SELECT returns no posts
What happens, when using the second version of the code, if your select does not return a result at all?
In a contrary to what you may believe the value of the variable will not be null - it will retain it's previous value!
This is because, as stated above, SQL will assign a value to the variable once per post - meaning it won't do anything with the variable if the result contains no posts. So, the variable will still have the value it had before you ran the statement.
With the SET-SELECT statement the value will be null
.
You could just use VideoLAN. VideoLAN will work as a server (or you can wrap your own C# application around it for more control). There are also .NET wrappers for the viewer that you can use and thus embed in your C# client.
I checked all the answers and the best one seemed to be (which isn't):
<img src="image.png?cache=none">
at first.
However, if you add cache=none parameter (which is static "none" word), it doesn't effect anything, browser still loads from cache.
Solution to this problem was:
<img src="image.png?nocache=<?php echo time(); ?>">
where you basically add unix timestamp to make the parameter dynamic and no cache, it worked.
However, my problem was a little different: I was loading on the fly generated php chart image, and controlling the page with $_GET parameters. I wanted the image to be read from cache when the URL GET parameter stays the same, and do not cache when the GET parameters change.
To solve this problem, I needed to hash $_GET but since it is array here is the solution:
$chart_hash = md5(implode('-', $_GET));
echo "<img src='/images/mychart.png?hash=$chart_hash'>";
Edit:
Although the above solution works just fine, sometimes you want to serve the cached version UNTIL the file is changed. (with the above solution, it disables the cache for that image completely) So, to serve cached image from browser UNTIL there is a change in the image file use:
echo "<img src='/images/mychart.png?hash=" . filemtime('mychart.png') . "'>";
filemtime() gets file modification time.
This will do it:
/[A-Za-z\u00C0-\u00FF ]+/.exec('hipopótamo maçã pólen ñ poção água língüa')
It explicitly selects a range of unicode characters. It will work for latin characters, but other strange characters may be out of this range.
I had to say:
sudo /etc/init.d/mysqld start
You can use inline css :
<td style = "text-align: center;">
If you use jQuery you can write:
$( _checkbox ).click( function( e ){ /*process event here*/ } )
Sadly I found the vim plugin mentioned not to be working with iTerm2 3.0.15 (to be fair I don't know if this broke on older versions) - but I found this hack instead.
Map command-p to do the paste and using iTerm2 vim keys. Obviously this only works for iTerm2.
How it works. I use "jk" to enter escape mode so you will also need:
:inoremap jk
in your .vimrc.
Then it just invokes P to enter paste mode, "+p to paste from the clipboard and then P to disable paste mode. hth.

I wasn't able to get some of the other answers to work on Chrome, Firefox, IE11, and Edge with the same code. I came up with the below and it appears to work for those browsers listed above.

Although @Remus Rusanu's is already an excelent answer, in case one is looking forward a better insight on SQL Server's Deadlock causes and trace strategies, I would suggest you to read Brad McGehee's How to Track Down Deadlocks Using SQL Server 2005 Profiler
You should change your code to make use of SqlParameters and adapt your insert statement to the following
string connetionString = "Data Source=UMAIR;Initial Catalog=Air; Trusted_Connection=True;" ;
// [ ] required as your fields contain spaces!!
string insStmt = "insert into Main ([First Name], [Last Name]) values (@firstName,@lastName)";
using (SqlConnection cnn = new SqlConnection(connetionString))
{
cnn.Open();
SqlCommand insCmd = new SqlCommand(insStmt, cnn);
// use sqlParameters to prevent sql injection!
insCmd.Parameters.AddWithValue("@firstName", textbox2.Text);
insCmd.Parameters.AddWithValue("@lastName", textbox3.Text);
int affectedRows = insCmd.ExecuteNonQuery();
MessageBox.Show (affectedRows + " rows inserted!");
}
Why not use: CopyOnWriteArraySet from java.util.concurrent?
I had the same problem, but nothing above worked...try a really simple solution...
Back up your .htaccess file. Delete it from your root directory. Then try accessing those directories. Its likely that whatever rewrite conditions you had in your file were causing those access issues. The index page should be picked up automatically on most hosts. :P
The prefix "Local" in JSR-310 (aka java.time-package in Java-8) does not indicate that there is a timezone information in internal state of that class (here: LocalDateTime
). Despite the often misleading name such classes like LocalDateTime
or LocalTime
have NO timezone information or offset.
You tried to format such a temporal type (which does not contain any offset) with offset information (indicated by pattern symbol Z). So the formatter tries to access an unavailable information and has to throw the exception you observed.
Solution:
Use a type which has such an offset or timezone information. In JSR-310 this is either OffsetDateTime
(which contains an offset but not a timezone including DST-rules) or ZonedDateTime
. You can watch out all supported fields of such a type by look-up on the method isSupported(TemporalField).. The field OffsetSeconds
is supported in OffsetDateTime
and ZonedDateTime
, but not in LocalDateTime
.
DateTimeFormatter formatter = DateTimeFormatter.ofPattern("yyyyMMdd HH:mm:ss.SSSSSS Z");
String s = ZonedDateTime.now().format(formatter);
UPDATE table1
SET column1 = (SELECT expression1
FROM table2
WHERE conditions)
[WHERE conditions];
You can use display:inline-block
.
This property allows a DOM element to have all the attributes of a block element, but keeping it inline. There's some drawbacks, but most of the time it's good enough. Why it's good and why it may not work for you.
EDIT: The only modern browser that has some problems with it is IE7. See Quirksmode.org
I was facing problem with Ngx
line chart xAxisTickFormatting
function which was called from HTML like this: [xAxisTickFormatting]="xFormat"
. I was unable to access my component's variable from the function declared. This solution helped me to resolve the issue to find the correct this. Hope this helps the Ngx
line chart, users.
instead of using the function like this:
xFormat (value): string {
return value.toString() + this.oneComponentVariable; //gives wrong result
}
Use this:
xFormat = (value) => {
// console.log(this);
// now you have access to your component variables
return value + this.oneComponentVariable

An API incompatibility I found, with Python 2.7 vs simplejson 3.3.1 is in whether output produces str or unicode objects. e.g.
>>> from json import JSONDecoder
>>> jd = JSONDecoder()
>>> jd.decode("""{ "a":"b" }""")
{u'a': u'b'}
vs
>>> from simplejson import JSONDecoder
>>> jd = JSONDecoder()
>>> jd.decode("""{ "a":"b" }""")
{'a': 'b'}
If the preference is to use simplejson, then this can be addressed by coercing the argument string to unicode, as in:
>>> from simplejson import JSONDecoder
>>> jd = JSONDecoder()
>>> jd.decode(unicode("""{ "a":"b" }""", "utf-8"))
{u'a': u'b'}
The coercion does require knowing the original charset, for example:
>>> jd.decode(unicode("""{ "a": "?????ßß?f?e?" }"""))
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
UnicodeDecodeError: 'ascii' codec can't decode byte 0xce in position 8: ordinal not in range(128)

git-meld-index -- quoting from the website:
git-meld-index runs meld -- or any other git difftool (kdiff3, diffuse, etc.) -- to allow you to interactively stage changes to the git index (also known as the git staging area).
This is similar to the functionality of git add -p, and git add --interactive. In some cases meld is easier / quicker to use than git add -p. That's because meld allows you, for example, to:
Usage
In a git repository, run:
git meld-index
You'll see meld (or your configured git difftool) pop up with:
LEFT: temporary directory contining files copied from your working tree
RIGHT: temporary directory with the contents of the index. This also includes files that are not yet in the index but are modified or untracked in the working copy -- in this case you'll see the file contents from HEAD.
Edit the index (right hand side) until happy. Remember to save when needed.
When you're done, close meld, and git-meld-index will update the index to match the contents of the temporary directory on the right hand side of meld that you just edited.
All,
Here a little bit twist with mysql-community-server 5.7 I share some steps, how to reset mysql5.7 root password or set password. it will work centos7 and RHEL7 as well.
step1. 1st stop your databases
service mysqld stop
step2. 2nd modify /etc/my.cnf file add "skip-grant-tables"
vi /etc/my.cnf
[mysqld] skip-grant-tables
step3. 3rd start mysql
service mysqld start
step4. select mysql default database
mysql -u root
mysql>use mysql;
step4. set a new password
mysql> update user set authentication_string=PASSWORD("yourpassword") where User='root'
;
step5 restart mysql database
service mysqld restart
mysql -u root -p
enjoy :)
I've been fighting with this all day: I have a Perl script that builds a set of tables by first doing a DROP IF EXISTS ...
on them and then CREATE
ing them. The DROP
succeeded, but on CREATE
I got this error message: table already exists
I finally got to the bottom of it: The new version of MySQL that I'm using has a default engine of InnoDB ("show engine \G;") I changed it in the my.cnf file to default to MyISAM, re-started MySQL, and now I no longer get the "table already exists" error.
I suggest using a custom Adapter, first create a Xml-file, for example layout/customlistview.xml
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="fill_parent" android:layout_height="wrap_content" >
<ImageView
android:id="@+id/image"
android:layout_alignParentRight="true"
android:paddingRight="4dp" />
<TextView
android:id="@+id/title"
android:layout_toLeftOf="@id/image"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textSize="23sp"
android:maxLines="1" />
<TextView
android:id="@+id/subtitle"
android:layout_toLeftOf="@id/image" android:layout_below="@id/title"
android:layout_width="wrap_content"
android:layout_height="wrap_content" />
</RelativeLayout>
Assuming you have a custom class like this
public class CustomClass {
private long id;
private String title, subtitle, picture;
public CustomClass () {
}
public CustomClass (long id, String title, String subtitle, String picture) {
this.id = id;
this.title= title;
this.subtitle= subtitle;
this.picture= picture;
}
//add getters and setters
}
And a CustomAdapter.java
uses the xml-layout
public class CustomAdapter extends ArrayAdapter {
private Context context;
private int resource;
private LayoutInflater inflater;
public CustomAdapter (Context context, List<CustomClass> values) { // or String[][] or whatever
super(context, R.layout.customlistviewitem, values);
this.context = context;
this.resource = R.layout.customlistview;
this.inflater = LayoutInflater.from(context);
}
@Override
public View getView(int position, View convertView, ViewGroup parent) {
convertView = (RelativeLayout) inflater.inflate(resource, null);
CustomClass item = (CustomClass) getItem(position);
TextView textviewTitle = (TextView) convertView.findViewById(R.id.title);
TextView textviewSubtitle = (TextView) convertView.findViewById(R.id.subtitle);
ImageView imageview = (ImageView) convertView.findViewById(R.id.image);
//fill the textviews and imageview with the values
textviewTitle = item.getTtile();
textviewSubtitle = item.getSubtitle();
if (item.getAfbeelding() != null) {
int imageResource = context.getResources().getIdentifier("drawable/" + item.getImage(), null, context.getPackageName());
Drawable image = context.getResources().getDrawable(imageResource);
}
imageview.setImageDrawable(image);
return convertView;
}
}
Did you manage to do it? Feel free to ask if you want more info on something :)
EDIT: Changed the adapter to suit a List instead of just a List
If you already know the indices:
list1 = ['x','y','z','a','b','c','d','e','f','g']
indices = [(0, 4), (5, 9)]
print [list1[s:e+1] for s,e in indices]
Note that we're adding +1 to the end to make the range inclusive...
>>> a = 'ZENOVW'
>>> b = sorted(a)
>>> print b
['E', 'N', 'O', 'V', 'W', 'Z']
sorted
returns a list, so you can make it a string again using join
:
>>> c = ''.join(b)
which joins the items of b
together with an empty string ''
in between each item.
>>> print c
'ENOVWZ'
ElementFormDefault has nothing to do with namespace of the types in the schema, it's about the namespaces of the elements in XML documents which comply with the schema.
Here's the relevent section of the spec:
Element Declaration Schema Component Property {target namespace} Representation If form is present and its ·actual value· is qualified, or if form is absent and the ·actual value· of elementFormDefault on the <schema> ancestor is qualified, then the ·actual value· of the targetNamespace [attribute] of the parent <schema> element information item, or ·absent· if there is none, otherwise ·absent·.
What that means is that the targetNamespace you've declared at the top of the schema only applies to elements in the schema compliant XML document if either elementFormDefault is "qualified" or the element is declared explicitly in the schema as having form="qualified".
For example: If elementFormDefault is unqualified -
<element name="name" type="string" form="qualified"></element>
<element name="page" type="target:TypePage"></element>
will expect "name" elements to be in the targetNamespace and "page" elements to be in the null namespace.
To save you having to put form="qualified" on every element declaration, stating elementFormDefault="qualified" means that the targetNamespace applies to each element unless overridden by putting form="unqualified" on the element declaration.
For string concatenation in C++, you should use the +
operator.
nametext = "Your name is" + name;
If using @Rule, the exception set is applied to all the test methods in the Test class.
This works for anonymous types, ExpandoObject
, Nancy.DynamicDictionary
or anything else that can be cast to IDictionary<string, object>
.
public static bool PropertyExists(dynamic obj, string name) {
if (obj == null) return false;
if (obj is IDictionary<string, object> dict) {
return dict.ContainsKey(name);
}
return obj.GetType().GetProperty(name) != null;
}
I'm not allowed to comment, so regarding Shane's answer, keep in mind that
wp_localize_scripts()
must be hooked to wp or admin enqueue scripts. So a good example would be as follows:
function local() {
wp_localize_script( 'js-file-handle', 'ajax', array(
'url' => admin_url( 'admin-ajax.php' )
) );
}
add_action('admin_enqueue_scripts', 'local');

Here's the better answer:
You can't implement a button clicked event for button cells in a DataGridViewButtonColumn. Instead, you use the DataGridView's CellClicked event and determine if the event fired for a cell in your DataGridViewButtonColumn. Use the event's DataGridViewCellEventArgs.RowIndex property to find out which row was clicked.
private void dataGridView1_CellClick(object sender, DataGridViewCellEventArgs e) {
// Ignore clicks that are not in our
if (e.ColumnIndex == dataGridView1.Columns["MyButtonColumn"].Index && e.RowIndex >= 0) {
Console.WriteLine("Button on row {0} clicked", e.RowIndex);
}
}

If fptr
is NULL
, then you don't have an open file. Therefore, you can't freopen
it, you should just fopen
it.
FILE *fptr;
fptr = fopen("scores.dat", "rb+");
if(fptr == NULL) //if file does not exist, create it
{
fptr = fopen("scores.dat", "wb");
}
note: Since the behavior of your program varies depending on whether the file is opened in read or write modes, you most probably also need to keep a variable indicating which is the case.
int main()
{
FILE *fptr;
char there_was_error = 0;
char opened_in_read = 1;
fptr = fopen("scores.dat", "rb+");
if(fptr == NULL) //if file does not exist, create it
{
opened_in_read = 0;
fptr = fopen("scores.dat", "wb");
if (fptr == NULL)
there_was_error = 1;
}
if (there_was_error)
{
printf("Disc full or no permission\n");
return EXIT_FAILURE;
}
if (opened_in_read)
printf("The file is opened in read mode."
" Let's read some cached data\n");
else
printf("The file is opened in write mode."
" Let's do some processing and cache the results\n");
return EXIT_SUCCESS;
}
NULL == NULL -> false (at least in DBMSs)
So you wouldn't be able to retrieve any relationships using a NULL value even with additional columns with real values.
The answer of philfreo is great, it works perfectly (cross-browser, with IE 7+). Just add my exp for the anchor tag inside li.
#footer ul li { display: inline; }
#footer ul li a { padding: 2px 4px; } /* no display: block here */
#footer ul li { position: relative; float: left; display: block; right: 50%; }
#footer ul li a {display: block; left: 0; }
You can override setMenuVisibility like this:
@Override
public void setMenuVisibility(final boolean visible) {
if (visible) {
//Do your stuff here
}
super.setMenuVisibility(visible);
}
def closest(list, Number):
aux = []
for valor in list:
aux.append(abs(Number-valor))
return aux.index(min(aux))
This code will give you the index of the closest number of Number in the list.
The solution given by KennyTM is the best overall, but in the cases you cannot use it (like brython), this function will do the work
I guess you're coming from a windows background. So i'll contrast them (i'm kind of new to linux too). I found user's reply to my comment, to be useful in figuring things out.
In Windows, a variable can be permanent or not. The term Environment variable includes a variable set in the cmd shell with the SET command, as well as when the variable is set within the windows GUI, thus set in the registry, and becoming viewable in new cmd windows. e.g. documentation for the set command in windows https://technet.microsoft.com/en-us/library/bb490998.aspx "Displays, sets, or removes environment variables. Used without parameters, set displays the current environment settings." In Linux, set does not display environment variables, it displays shell variables which it doesn't call/refer to as environment variables. Also, Linux doesn't use set to set variables(apart from positional parameters and shell options, which I explain as a note at the end), only to display them and even then only to display shell variables. Windows uses set for setting and displaying e.g. set a=5, linux doesn't.
In Linux, I guess you could make a script that sets variables on bootup, e.g. /etc/profile
or /etc/.bashrc
but otherwise, they're not permanent. They're stored in RAM.
There is a distinction in Linux between shell variables, and environment variables. In Linux, shell variables are only in the current shell, and Environment variables, are in that shell and all child shells.
You can view shell variables with the set
command (though note that unlike windows, variables are not set in linux with the set command).
set -o posix; set
(doing that set -o posix once first, helps not display too much unnecessary stuff). So set
displays shell variables.
You can view environment variables with the env
command
shell variables are set with e.g. just a = 5
environment variables are set with export, export also sets the shell variable
Here you see shell variable zzz set with zzz = 5, and see it shows when running set
but doesn't show as an environment variable.
Here we see yyy set with export, so it's an environment variable. And see it shows under both shell variables and environment variables
$ zzz=5
$ set | grep zzz
zzz=5
$ env | grep zzz
$ export yyy=5
$ set | grep yyy
yyy=5
$ env | grep yyy
yyy=5
$
other useful threads
https://unix.stackexchange.com/questions/176001/how-can-i-list-all-shell-variables
https://askubuntu.com/questions/26318/environment-variable-vs-shell-variable-whats-the-difference
Note- one point which elaborates a bit and is somewhat corrective to what i've written, is that, in linux bash, 'set' can be used to set "positional parameters" and "shell options/attributes", and technically both of those are variables, though the man pages might not describe them as such. But still, as mentioned, set won't set shell variables or environment variables). If you do set asdf
then it sets $1 to asdf, and if you do echo $1
you see asdf. If you do set a=5
it won't set the variable a, equal to 5. It will set the positional parameter $1 equal to the string of "a=5". So if you ever saw set a=5 in linux it's probably a mistake unless somebody actually wanted that string a=5, in $1. The other thing that linux's set can set, is shell options/attributes. If you do set -o you see a list of them. And you can do for example set -o verbose
, off, to turn verbose on(btw the default happens to be off but that makes no difference to this). Or you can do set +o verbose
to turn verbose off. Windows has no such usage for its set command.
Best way to do this is to use a function:
<div ng-repeat="product in products | filter: myFilter">
$scope.myFilter = function (item) {
return item === 'red' || item === 'blue';
};
Alternatively, you can use ngHide or ngShow to dynamically show and hide elements based on a certain criteria.
This worked for me. Add this to image css:
img
{
display: block;
margin: auto;
}
because it is autoincrement, here's my take:
Select * from tbl
where certainconditionshere
and autoincfield >= (select max(autoincfield) from tbl) - $n
If you save the excel file as a CSV file then you can import it into a mysql database using tools such as PHPMyAdmin
Im not sure if this would help in your situation, but a csv file either manually or programatically would be a lot easier to parse into a database than an excel file I would have thought.
EDIT: I would however suggest looking at the other answers rather than mine since @diEcho answer seems more appropriate.
Restart intelliJ and import project as maven if it is a maven project
Above answers did not work for me.
Adding the attribute preserveAspectRatio="xMidYMin"
to the <svg>

Update 2018-07-23
As was just pointed out in the comments, this question was about getting a screenshot from the command line. Sorry, I just read over that. So here is the correct answer:
As of Firefox 57 you can create a screenshot in headless mode like this:
firefox -screenshot https://developer.mozilla.com
Read more in the documentation.
Update 2017-06-15
As of Firefox 55 there is Firefox Screenshots as a more flexible alternative. As of Firefox 57 Screenshots can capture a full page, too.
Original answer
Since Firefox 32 there is also a full page screenshot button in the developer tools (F12). If it is not enabled go to the developer tools settings (gear button) and choose "Take a fullpage screenshot" at the "Available Toolbox Buttons" section.
source: developer.mozilla.org
By default the screenshots are saved in the download directory. This works similar to screenshot --fullpage
in the toolbar.
Highlight the cells, format cells, select Custom then select zero.
Supplement to Mario Knezovic 's answer:
class IA
{
public:
virtual int getNum() const = 0;
};
class BaseA : public IA
{
public:
inline virtual int getNum() const final {return ...};
};
class ImplA : public BaseA {...};
IA* pa = ...;
...
ImplA* impla = static_cast<ImplA*>(pa);
//the following line should cause compiler to use the inlined function BaseA::getNum(),
//instead of dynamic binding (via vtable or something).
//any class/subclass of BaseA will benefit from it
int n = impla->getNum();
The above code shows the theory, but not actually tested on real compilers. Much appreciated if anyone paste a disassembled output.
I have encountered similar mistakes, and later found that my password is wrong.
Make sure you specify pass header=None
and add usecols=[3,6]
for the 4th and 7th columns.
You have an error in your syntax here:
this._possessions = new Thing[100]();
This doesn't create an "array of things". To create an array of things, you can simply use the array literal expression:
this._possessions = [];
Of the array constructor if you want to set the length:
this._possessions = new Array(100);
I have created a brief working example you can try in the playground.
module Entities {
class Thing {
}
export class Person {
private _name: string;
private _possessions: Thing[];
private _mostPrecious: Thing;
constructor (name: string) {
this._name = name;
this._possessions = [];
this._possessions.push(new Thing())
this._possessions[100] = new Thing();
}
}
}
Here's a more flexible version, which allows you to create reusable sort functions, and sort by any field.
const sort_by = (field, reverse, primer) => {_x000D_
_x000D_
const key = primer ?_x000D_
function(x) {_x000D_
return primer(x[field])_x000D_
} :_x000D_
function(x) {_x000D_
return x[field]_x000D_
};_x000D_
_x000D_
reverse = !reverse ? 1 : -1;_x000D_
_x000D_
return function(a, b) {_x000D_
return a = key(a), b = key(b), reverse * ((a > b) - (b > a));_x000D_
}_x000D_
}_x000D_
_x000D_
_x000D_
//Now you can sort by any field at will..._x000D_
_x000D_
const homes=[{h_id:"3",city:"Dallas",state:"TX",zip:"75201",price:"162500"},{h_id:"4",city:"Bevery Hills",state:"CA",zip:"90210",price:"319250"},{h_id:"5",city:"New York",state:"NY",zip:"00010",price:"962500"}];_x000D_

You can see all routes via rake:routes (this might help you).
Make sure overflow is set to "scroll" not "auto." With that said, in OS X Lion, overflow set to "scroll" behaves more like auto in that scrollbars will still only show when being used. So if any the solutions above don't appear to be working that might be why.
This is what you'll need to fix it:
::-webkit-scrollbar {
-webkit-appearance: none;
width: 7px;
}
::-webkit-scrollbar-thumb {
border-radius: 4px;
background-color: rgba(0, 0, 0, .5);
-webkit-box-shadow: 0 0 1px rgba(255, 255, 255, .5);
}
You can style it accordingly if you don't like the default.
You can download the Wikipedia database directly and parse all pages to XML with Wiki Parser, which is a standalone application. The first paragraph is a separate node in the resulting XML.
Alternatively, you can extract the first paragraph from its plain-text output.
if wants to convert UTC date to milliseconds
syntax : Date.UTC(year, month, ?day, ?hours, ?min, ?sec, ?milisec);
e.g :
date_in_mili = Date.UTC(2020, 07, 03, 03, 40, 40, 40);
console.log('miliseconds', date_in_mili);
I had this same problem. The session ID is sent in a cookie, but since the request is cross-domain, the browser's security settings will block the cookie from being sent.
Solution: Generate the session ID on the client (in the browser), use Javascript sessionStorage to store the session ID then send the session ID with each request to the server.
I struggled a lot with this issue, and there weren't many good answers around. Here's an article detailing the solution: Javascript Cross-Domain Request With Session
Using this code might help. It solved my problem!
mb_convert_encoding($post["post"],'UTF-8','UTF-8');
or like that
mb_convert_encoding($string,'UTF-8','UTF-8');
I am facing same problem, I was fixed it by generating gradle project and then adding lib project to android studio
First, See build.gradle file is present in project root directory
if not then, Create gradle project,
For what its worth, in Pycharm it is: Right click on the root folder->Mark Directory as-> Sources Root
Your problem is most likely with the video file, not the code. Your video is most likely not "safe for streaming". See where to place videos to stream android for more.
You can do a post/get using a library which allows you to use HttpClient with strongly-typed callbacks.
The data and the error are available directly via these callbacks.
The library is called angular-extended-http-client.

Very easy to use.
In the traditional approach you return Observable<HttpResponse<
T>
> from Service API. This is tied to HttpResponse.
With this approach you have to use .subscribe(x => ...) in the rest of your code.
This creates a tight coupling between the http layer and the rest of your code.
You only deal with your Models in these strongly-typed callbacks.
Hence, The rest of your code only knows about your Models.
The strongly-typed callbacks are
Success:
T
>T
>Failure:
TError
>TError
>import { HttpClientExtModule } from 'angular-extended-http-client';
and in the @NgModule imports
imports: [
.
.
.
HttpClientExtModule
],
export class SearchModel {
code: string;
}
//Normal response returned by the API.
export class RacingResponse {
result: RacingItem[];
}
//Custom exception thrown by the API.
export class APIException {
className: string;
}
In your Service, you just create params with these callback types.
Then, pass them on to the HttpClientExt's get method.
import { Injectable, Inject } from '@angular/core'
import { SearchModel, RacingResponse, APIException } from '../models/models'
import { HttpClientExt, IObservable, IObservableError, ResponseType, ErrorType } from 'angular-extended-http-client';
.
.
@Injectable()
export class RacingService {
//Inject HttpClientExt component.
constructor(private client: HttpClientExt, @Inject(APP_CONFIG) private config: AppConfig) {
}
//Declare params of type IObservable<T> and IObservableError<TError>.
//These are the success and failure callbacks.
//The success callback will return the response objects returned by the underlying HttpClient call.
//The failure callback will return the error objects returned by the underlying HttpClient call.
searchRaceInfo(model: SearchModel, success: IObservable<RacingResponse>, failure?: IObservableError<APIException>) {
let url = this.config.apiEndpoint;
this.client.post<SearchModel, RacingResponse>(url, model,
ResponseType.IObservable, success,
ErrorType.IObservableError, failure);
}
}
In your Component, your Service is injected and the searchRaceInfo API called as shown below.
search() {
this.service.searchRaceInfo(this.searchModel, response => this.result = response.result,
error => this.errorMsg = error.className);
}
Both, response and error returned in the callbacks are strongly typed. Eg. response is type RacingResponse and error is APIException.

This VBA code will refresh all pivot tables/charts in the workbook.
Sub RefreshAllPivotTables()
Dim PT As PivotTable
Dim WS As Worksheet
For Each WS In ThisWorkbook.Worksheets
For Each PT In WS.PivotTables
PT.RefreshTable
Next PT
Next WS
End Sub
Another non-programatic option is:
This will refresh the pivot table each time the workbook is opened.
