In order to make
http://localhost:8080
work, tomcat has to be started first. You can check server.xml file in conf folder for the port information. You can search if tomcat is installed on your machine. Just go to start and then type tomcat. If it is installed it will give you the directory where it is installed. Then you can select that path and run it from command prompt. Example if tomcat is installed in C:\Programfile\tomcat. You need to set this path in command prompt,go to bin folder and startup. Example: C:\Programfile\tomcat\bin\startup. Else you can also run it by directly going to the path and run startup batch file.
It is not clear why you want to do this. If you want to get the correct numerical value, you could use unary +
[docs]:
value = +value;
If you just want to format the text, then regex could be better. It depends on the values you are dealing with I'd say. If you only have integers, then
input.value = +input.value;
is fine as well. Of course it also works for float values, but depending on how many digits you have after the point, converting it to a number and back to a string could (at least for displaying) remove some.
It sounds like you're not instantiating your class. That's the primary reason I get the "an object reference is required" error.
MyClass myClass = new MyClass();
once you've added that line you can then call your method
myClass.myMethod();
Also, are all of your classes in the same namespace? When I was first learning c# this was a common tripping point for me.
This happens when you declared the JSF Managed Bean as
@RequestScoped;
when you should declare as
@SessionScoped;

Thanks Jason Rogers's answer first.
In Android && cpp should be this:
const char *nativeString = env->GetStringUTFChars(javaString, nullptr);
// use your string
env->ReleaseStringUTFChars(javaString, nativeString);
Can fix this errors:
1.error: base operand of '->' has non-pointer type 'JNIEnv {aka _JNIEnv}'
2.error: no matching function for call to '_JNIEnv::GetStringUTFChars(JNIEnv*&, _jstring*&, bool)'
3.error: no matching function for call to '_JNIEnv::ReleaseStringUTFChars(JNIEnv*&, _jstring*&, char const*&)'
4.add "env->DeleteLocalRef(nativeString);" at end.
For Android 6.0+ the game has changed so i suggest you use this;
The best way to go is during runtime else you get permission errors.

Follow the below simple steps you will able to get the result
Step 1- Create one internal function getDetailFromExternal in your back end. step 2- In that function call the external url by using cUrl like below function
function getDetailFromExternal($p1,$p2) {
$url = "http://request url with parameters";
$ch = curl_init();
curl_setopt_array($ch, array(
CURLOPT_URL => $url,
CURLOPT_RETURNTRANSFER => true
));
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 0);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0);
$output = curl_exec($ch);
curl_close($ch);
echo $output;
exit;
}
Step 3- Call that internal function from your front end by using javascript/jquery Ajax.
Through a combination of the suggestions I got, I came up with this:
private void DrawLetter()
{
Graphics g = this.CreateGraphics();
float width = ((float)this.ClientRectangle.Width);
float height = ((float)this.ClientRectangle.Width);
float emSize = height;
Font font = new Font(FontFamily.GenericSansSerif, emSize, FontStyle.Regular);
font = FindBestFitFont(g, letter.ToString(), font, this.ClientRectangle.Size);
SizeF size = g.MeasureString(letter.ToString(), font);
g.DrawString(letter, font, new SolidBrush(Color.Black), (width-size.Width)/2, 0);
}
private Font FindBestFitFont(Graphics g, String text, Font font, Size proposedSize)
{
// Compute actual size, shrink if needed
while (true)
{
SizeF size = g.MeasureString(text, font);
// It fits, back out
if (size.Height <= proposedSize.Height &&
size.Width <= proposedSize.Width) { return font; }
// Try a smaller font (90% of old size)
Font oldFont = font;
font = new Font(font.Name, (float)(font.Size * .9), font.Style);
oldFont.Dispose();
}
}
So far, this works flawlessly.
The only thing I would change is to move the FindBestFitFont() call to the OnResize() event so that I'm not calling it every time I draw a letter. It only needs to be called when the control size changes. I just included it in the function for completeness.
I recently had to find out why this didn't work too.
The javascript you want to call from the child iframe needs to be in the head of the parent. If it is in the body, the script is not available in the global scope.
<head>
<script>
function abc() {
alert("sss");
}
</script>
</head>
<body>
<iframe id="myFrame">
<a onclick="parent.abc();" href="#">Click Me</a>
</iframe>
</body>
Hope this helps anyone that stumbles upon this issue again.
You may consider using ex
(which is a standard Unix command-based editor):
ex +g/match/d -cwq file
where:
+
executes given Ex command (man ex
), same as -c
which executes wq
(write and quit)g/match/d
- Ex command to delete lines with given match
, see: Power of gThe above example is a POSIX-compliant method for in-place editing a file as per this post at Unix.SE and POSIX specifications for ex
.
The difference with sed
is that:
sed
is a Stream EDitor, not a file editor.BashFAQ
Unless you enjoy unportable code, I/O overhead and some other bad side effects. So basically some parameters (such as in-place/-i
) are non-standard FreeBSD extensions and may not be available on other operating systems.
It's not recommended to update the server configuration like server.xml or ROOT.xml.
You can put a context.xml configuration file under your web-application META-INF directory, with the context path setting included. This will override the default server setting?
i.e.:
<Context docBase="yourAppName" path="/yourAppPath" reloadable="true">
LIKE
and the equality operator have different purposes, they don't do the same thing:
=
is much faster, whereas LIKE
can interpret wildcards. Use =
wherever you can and LIKE
wherever you must.
SELECT * FROM user WHERE login LIKE 'Test%';
Sample matches:
TestUser1
TestUser2
TestU
Test
:-) Once I found myself in the same situation, there was no jQuery plugin matching my requeriments, so I spend some time developing my own one: colResizable
colResizable is a free jQuery plugin to resize table columns dragging them manually. It is compatible with both mouse and touch devices and has some nice features such as layout persistence after page refresh or postback. It works with both percentage and pixel-based table layouts.
It is tiny in size (colResizable 1.0 is only 2kb) and it is fully compatible with all major browsers (IE7+, Firefox, Chrome and Opera).
colResizable was developed since no other similar plugin with the below listed features was found:
colResizable is the most polished plugin to resize table columns out there. It has plenty of customization possibilities and it is also compatible with touch devices. But probably the most interesting feature which is making colResizable the greatest choice is that it is compatible with both pixel-based and fluid percentage table layouts. But, what does it mean?
If the width of a table is set to, lets say 90%, and the column widths are modified using colResizable, when the browser is resized columns widths are resized proportionally. While other plugins does behave odd, colResizable does its job just as expected.
colResizable is also compatible with table max-width attribute: if the sum of all columns exceed the table's max-width, they are automatically fixed and updated.
Another great advantage compared with other plugins is that it is compatible with page refresh, postbacks and even partial postbacks if the table is located inside of an updatePanel. It is compatible with all major browsers (IE7+, Firefox, Chrome and Opera), while other plugins fail with old IE versions.
$("#sample").colResizable({
liveDrag:true
});
This lifecycle method is invoked as soon as the updating happens. The most common use case for the componentDidUpdate() method is updating the DOM in response to prop or state changes.
You can call setState() in this lifecycle, but keep in mind that you will need to wrap it in a condition to check for state or prop changes from previous state. Incorrect usage of setState() can lead to an infinite loop. Take a look at the example below that shows a typical usage example of this lifecycle method.
componentDidUpdate(prevProps) {
//Typical usage, don't forget to compare the props
if (this.props.userName !== prevProps.userName) {
this.fetchData(this.props.userName);
}
}
Notice in the above example that we are comparing the current props to the previous props. This is to check if there has been a change in props from what it currently is. In this case, there won’t be a need to make the API call if the props did not change.

If the server accessible with RPC (basically, if you can access a shared folder on it), you could free some memory and thus let the RDP service work properly. The following windows native commands can be used:
To get the list of memory consuming tasks:
tasklist /S <remote_server> /V /FI "MEMUSAGE gt 10000"
To kill a task by its name:
taskkill /S <remote_server> /IM <process_image_name> /F
To show the list of desktop sessions:
qwinsta.exe /SERVER:<remote_server>
To close an old abandoned desktop session:
logoff <session_id> /SERVER:<remote_server>
After some memory is freed, the RDP should start working.
The cex
parameter will do that for you.
a <- c(3, 2, 2, 2, 1, 2 )
barplot(a, beside = T,
col = 1:6, space = c(0, 2))
legend("topright",
legend = c("a", "b", "c", "d", "e", "f"),
fill = 1:6, ncol = 2,
cex = 0.75)
Another common technique is to place the function name in the first column. This allows the definition to be found with a simple search.
int
main(int argc, char *argv[])
{
...
}
The above function could then be found with /^main
inside the file or with :grep -r '^main' *.c
in a directory. As long as code is properly indented the only time the identifier will occur at the beginning of a line is at the function definition.
Of course, if you aren't using ctags from this point on you should be ashamed of yourself! However, I find this coding standard a helpful addition as well.
Use the ampersand &
to glue variables together:
$url = "http://localhost/main.php?email=$email_address&event_id=$event_id";
// ^ start of vars ^next var
You should be able to put them in your ~/matlab on unix.
I'm not sure which directory matlab looks in for windows, but you should be able to figure it out by executing userpath
from the matlab command line.
Several of the examples here create a new Random
instance, but this is unnecessary. There is also no reason to use synchronized
as one solution does. Instead, take advantage of the methods on the ThreadLocalRandom
class:
double randomGenerator() {
return ThreadLocalRandom.current().nextDouble(0.5);
}
"... that are independent of their timezone"
var timezone = d.getTimezoneOffset() // difference in minutes from GMT
If the values are not unique, the safe way to inverse the map is by using java 8's groupingBy function
Map<String, Integer> map = new HashMap<>();
map.put("a",1);
map.put("b",2);
Map<Integer, List<String>> mapInversed =
map.entrySet()
.stream()
.collect(Collectors.groupingBy(Map.Entry::getValue, Collectors.mapping(Map.Entry::getKey, Collectors.toList())))
# To sort the list in place...
ut.sort(key=lambda x: x.count, reverse=True)
# To return a new list, use the sorted() built-in function...
newlist = sorted(ut, key=lambda x: x.count, reverse=True)
More on sorting by keys.
Use:
public void onClick(View v) {
switch(v.getId()){
case R.id.Button_MyCards: /** Start a new Activity MyCards.java */
Intent intent = new Intent(this, MyCards.class);
this.startActivity(intent);
break;
case R.id.Button_Exit: /** AlerDialog when click on Exit */
MyAlertDialog();
break;
}
}
Note that this will not work in Android library projects (due to http://tools.android.com/tips/non-constant-fields) where you will need to use something like:
int id = view.getId();
if (id == R.id.Button_MyCards) {
action1();
} else if (id == R.id.Button_Exit) {
action2();
}
You can do this programmatically using a VBA macro. You can make the sheet hidden or very hidden:
Sub HideSheet()
Dim sheet As Worksheet
Set sheet = ActiveSheet
' this hides the sheet but users will be able
' to unhide it using the Excel UI
sheet.Visible = xlSheetHidden
' this hides the sheet so that it can only be made visible using VBA
sheet.Visible = xlSheetVeryHidden
End Sub
For ones that looking this solution in React, If you want to use the spread operator inside style, you should use: babel-plugin-transform-object-rest-spread.
Install it by npm module and configure your .babelrc as such:
{
"presets": ["env", "react"],
"plugins": ["transform-object-rest-spread"]
}
Then you can use like...
const sizing = { width: 200, height: 200 }
<div
className="dragon-avatar-image-background"
style={{ backgroundColor: blue, ...sizing }}
/>
More info: https://babeljs.io/docs/en/babel-plugin-transform-object-rest-spread/
I had the same problem with Xcode. I followed steps you gave and it didn't work. I became crazy because in every forum I saw, all clues for this problem are the one you gave. I finally saw I put a space after the malloc_error_break, I suppressed it and now it works. A dumb problem but if the solution doesn't work, be sure you haven't put any space before and after the malloc_error_break.
Hope this message will help..
If you'd like to know the value of the default selected radio button before a click event, try this:

These are the shift operators
x << y Returns x with the bits shifted to the left by y places (and new bits on the right-hand-side are zeros). This is the same as multiplying x by 2**y.
x >> y Returns x with the bits shifted to the right by y places. This is the same as //'ing x by 2**y.
NSString *string = /* Assume this exists. */;
int value = [string intValue];
You need to set index=False
in to_excel
in order for it to not write the index column out, this semantic is followed in other Pandas IO tools, see http://pandas.pydata.org/pandas-docs/stable/generated/pandas.DataFrame.to_excel.html and http://pandas.pydata.org/pandas-docs/stable/io.html
As an alternative approach to trying to parse the string and catching NumberFormatException
, you could use a regex; e.g.
if (Pattern.compile("-?[0-9]+").matches(str)) {
// its an integer
}
This is likely to be faster, especially if you precompile and reuse the regex.
However, the problem with this approach is that Integer.parseInt(str)
will also fail if str
represents a number that is outside range of legal int
values. While it is possible to craft a regex that only matches integers in the range Integer.MIN_INT
to Integer.MAX_INT
, it is not a pretty sight. (And I am not going to try it ...)
On the other hand ... it may be acceptable to treat "not an integer" and "integer too large" separately for validation purposes.

WebDriver driver = new FirefoxDriver();

Just wanted to note that the following implementation is wrong when value
is not a primitive type:
public class Thing
{
public Object value;
public Thing (Object x)
{
this.value = x;
}
@Override
public boolean equals(Object object)
{
boolean sameSame = false;
if (object != null && object instanceof Thing)
{
sameSame = this.value == ((Thing) object).value;
}
return sameSame;
}
}
In that case I propose the following:
public class Thing {
public Object value;
public Thing (Object x) {
value = x;
}
@Override
public boolean equals(Object object) {
if (object != null && object instanceof Thing) {
Thing thing = (Thing) object;
if (value == null) {
return (thing.value == null);
}
else {
return value.equals(thing.value);
}
}
return false;
}
}
Add Unique Index on your table:

is work very well
Had this issue after a reinstall today. Make sure the Application Experience service is started and not set to disabled. If its set to manual, I believe VS will start it.
You can use all
> all(1:6 %in% 0:36)
[1] TRUE
> all(1:60 %in% 0:36)
[1] FALSE
On a similar note, if you want to check whether any of the elements is TRUE you can use any
> any(1:6 %in% 0:36)
[1] TRUE
> any(1:60 %in% 0:36)
[1] TRUE
> any(50:60 %in% 0:36)
[1] FALSE
I experienced a similar problem, I was getting ERR_HTTP2_PROTOCOL_ERROR on one of the HTTP GET requests.
I noticed that the Chrome update was pending, so I updated the Chrome browser to the latest version and the error was gone next time when I relaunched the browser.
You have to give a valid username. For example, to run query with user root
you have to type the following command and then enter password when prompted:
mysql -u root -p
Once you are connected, prompt will be something like:
mysql>
Here you can write your query, after database selection, for example:
mysql> USE your_database;
mysql> SELECT * FROM your_table;
To disable the "Show Entries" label, add the code dom: 'Bfrtip' or you can add "bInfo": false
$('#example').DataTable({
dom: 'Bfrtip'
})
The cleanest method would be to add a class with pointer-events:none when you want to disable a click. It would function like a normal label.
.disableClick{
pointer-events: none;
}
Other way to center one line text is:
.parent{
position: relative;
}
.child{
position: absolute;
top: 50%;
line-height: 0;
}
or just
.parent{
overflow: hidden; /* if this ins't here the parent will adopt the 50% margin of the child */
}
.child{
margin-top: 50%;
line-height: 0;
}
I resolve this is by changing the version no of recyleview to recyclerview-v7:24.2.1. Please check your dependencies and use the proper version number.
Just use IDA PRO (https://www.hex-rays.com/products/ida/index.shtml) to disassemble the file, and search for some known command line option (using Search...Text) - in that section you will then typically see all the command line options - for the program (LIB2NIST.exe) in the screenshot below, for example, it shows a documented command line option (/COM2TAG) but also some undocumented ones, like /L. Hope this helps?
I used James Nelli answer and added onpaste="return false;" (Håvard Geithus) to ensure only integer is entered into the input. Even if you tried to paste, it will not allow it.
Change the "package source" in nuget to All
Details:
None of the above helped in my case.
My problem was that I restricted to only one private feed. Once I changed the "package source" to All
, my problem was solved. I believe the crux of the matter is that my private pkg has a dependency on other pkgs from nuget.org.
I hope this can help someone
For no InnoDB solution: you can use a procedure
don't forgot to set the delimiter for storing the procedure with ;
CREATE PROCEDURE myproc(OUT id INT, IN otherid INT, IN title VARCHAR(255))
BEGIN
LOCK TABLES `table1` WRITE;
INSERT INTO `table1` ( `title` ) VALUES ( @title );
SET @id = LAST_INSERT_ID();
UNLOCK TABLES;
INSERT INTO `table2` ( `parentid`, `otherid`, `userid` ) VALUES (@id, @otherid, 1);
END
And you can use it...
SET @myid;
CALL myproc( @myid, 1, "my title" );
SELECT @myid;
The issue is that you're not saving the mysqli connection. Change your connect to:
$aVar = mysqli_connect('localhost','tdoylex1_dork','dorkk','tdoylex1_dork');
And then include it in your query:
$query1 = mysqli_query($aVar, "SELECT name1 FROM users
ORDER BY RAND()
LIMIT 1");
$aName1 = mysqli_fetch_assoc($query1);
$name1 = $aName1['name1'];
Also don't forget to enclose your connections variables as strings as I have above. This is what's causing the error but you're using the function wrong, mysqli_query returns a query object but to get the data out of this you need to use something like mysqli_fetch_assoc http://php.net/manual/en/mysqli-result.fetch-assoc.php to actually get the data out into a variable as I have above.

.click(function (event) {
event.preventDefault();
});
$("#tabs").tabs();

np.max
is just an alias for np.amax
. This function only works on a single input array and finds the value of maximum element in that entire array (returning a scalar). Alternatively, it takes an axis
argument and will find the maximum value along an axis of the input array (returning a new array).
>>> a = np.array([[0, 1, 6],
[2, 4, 1]])
>>> np.max(a)
6
>>> np.max(a, axis=0) # max of each column
array([2, 4, 6])
The default behaviour of np.maximum
is to take two arrays and compute their element-wise maximum. Here, 'compatible' means that one array can be broadcast to the other. For example:
>>> b = np.array([3, 6, 1])
>>> c = np.array([4, 2, 9])
>>> np.maximum(b, c)
array([4, 6, 9])
But np.maximum
is also a universal function which means that it has other features and methods which come in useful when working with multidimensional arrays. For example you can compute the cumulative maximum over an array (or a particular axis of the array):
>>> d = np.array([2, 0, 3, -4, -2, 7, 9])
>>> np.maximum.accumulate(d)
array([2, 2, 3, 3, 3, 7, 9])
This is not possible with np.max
.
You can make np.maximum
imitate np.max
to a certain extent when using np.maximum.reduce
:
>>> np.maximum.reduce(d)
9
>>> np.max(d)
9
Basic testing suggests the two approaches are comparable in performance; and they should be, as np.max()
actually calls np.maximum.reduce
to do the computation.
You know, there might be an easier way but the first thing that pops to mind is:
Declare @SumVal int;
Select @SumVal=Sum(Amount) From Expense;
Print @SumVal;
You can, of course, print any number of fields from the table in this way. Of course, if you want to print all of the results from a query that returns multiple rows, you'd just direct your output appropriately (e.g. to Text).
Since PikkuKatja and glallen asked for a more general solution and I cannot comment yet, I'll write an answer. You can combine statements as in:
> df[df=="" | df==12] <- NA
> df
A B
1 <NA> <NA>
2 xyz <NA>
3 jkl 100
For factors, zxzak's code already yields factors:
> df <- data.frame(list(A=c("","xyz","jkl"), B=c(12,"",100)))
> str(df)
'data.frame': 3 obs. of 2 variables:
$ A: Factor w/ 3 levels "","jkl","xyz": 1 3 2
$ B: Factor w/ 3 levels "","100","12": 3 1 2
If in trouble, I'd suggest to temporarily drop the factors.
df[] <- lapply(df, as.character)
You're missing a close paren in this line:
fi2=0.460*scipy.sqrt(1-(Tr-0.566)**2/(0.434**2)+0.494
There are three ( and only two ).
I hope This will help you.

You don't need to assign names
to list
or []
or anything else until you wish to use it.
It's neater to use a list comprehension to make the list of names.
shuffle
modifies the list you pass to it. It always returns None
If you are using a context manager (with ...
) you don't need to close the file explicitly
from random import shuffle
with open('names') as f:
names = [name.rstrip() for name in f if not name.isspace()]
shuffle(names)
assert len(names) > 100
Apart from the accepted answer, you can also initialise your rows in the following manner -
matrix[i] = [0]*n
Therefore, the following piece of code will work -
m = int(input('number of rows, m = '))
n = int(input('number of columns, n = '))
matrix = []
# initialize the number of rows
for i in range(0,m):
matrix += [0]
# initialize the matrix
for i in range (0,m):
matrix[i] = [0]*n
for i in range (0,m):
for j in range (0,n):
print ('entry in row: ',i+1,' column: ',j+1)
matrix[i][j] = int(input())
print (matrix)
Even better, try an OrderedDict (assuming you want something like a list). Closer to a list than a regular dict since the keys have an order just like list elements have an order. With a regular dict, the keys have an arbitrary order.
Note that this is available in Python 3 and 2.7. If you want to use with an earlier version of Python you can find installable modules to do that.
We have used the combination of:
Cobian Backup for scheduling/maintenance
ExpressMaint for backup
Both of these are free. The process is to script ExpressMaint to take a backup as a Cobian "before Backup" event. I usually let this overwrite the previous backup file. Cobian then takes a zip/7zip out of this and archives these to the backup folder. In Cobian you can specify the number of full copies to keep, make multiple backup cycles etc.
ExpressMaint command syntax example:
expressmaint -S HOST\SQLEXPRESS -D ALL_USER -T DB -R logpath -RU WEEKS -RV 1 -B backuppath -BU HOURS -BV 3
this was available in php 5.6 in php 7+ you should declare the array first
$users = array(); // not $users = ";
$users[] = "762";
If you are using zsh do the following.
Open .zshrc file nano $HOME/.zshrc
You will see the commented $PATH variable here
# If you come from bash you might have to change your $PATH.
# export PATH=$HOME/bin:/usr/local/...
Remove the comment symbol(#) and append your new path using a separator(:) like this.
export PATH=$HOME/bin:/usr/local/bin:/Users/ebin/Documents/Softwares/mongoDB/bin:$PATH
source $HOME/.zshrc
You're done !!!
I played a bit with it and the syntax seems to get quite strange when a constructor takes no arguments. Let me give an example:
#include <iostream>
using namespace std;
class Thing
{
public:
Thing();
};
Thing::Thing()
{
cout << "Hi" << endl;
}
int main()
{
//Thing myThing(); // Does not work
Thing myThing; // Works
}
so just writing Thing myThing w/o brackets actually calls the constructor, while Thing myThing() makes the compiler thing you want to create a function pointer or something ??!!
If this is the only application where you're going to use this variable, Felix's approach is excellent. However, if you're writing a jQuery plugin, consider "namespacing" (details on the quotes later...) variables and functions needed under the jQuery object. For example, I'm currently working on a jQuery popup menu that I've called miniMenu. Thus, I've defined a "namespace" miniMenu
under jQuery, and I place everything there.
The reason I use quotes when I talk about JavaScript namespaces is that they aren't really namespaces in the normal sense. Instead, I just use a JavaScript object and place all my functions and variables as properties of this object.
Also, for convenience, I usually sub-space the plugin namespace with an i
namespace for stuff that should only be used internally within the plugin, so as to hide it from users of the plugin.
This is how it works:
// An object to define utility functions and global variables on:
$.miniMenu = new Object();
// An object to define internal stuff for the plugin:
$.miniMenu.i = new Object();
Now I can just do $.miniMenu.i.globalVar = 3
or $.miniMenu.i.parseSomeStuff = function(...) {...}
whenever I need to save something globally, and I still keep it out of the global namespace.
One other cause to this problem is if you open a project from a mapped drive - Visual Studio handles such projects properly, but apparently Nunit doesn't support them.
Copying the project to a physical fixed the issue.
I think no one has given the correct answer to the question. My working solution is : 1. Just declare another class along with container-fluid class example(.maxx):
<div class="container-fluid maxx">_x000D_
<div class="row">_x000D_
<div class="col-sm-12">_x000D_
<p>Hello</p>_x000D_
</div>_x000D_
</div>_x000D_
</div>
_x000D_
.container-fluid.maxx {_x000D_
padding-left: 0px;_x000D_
padding-right: 0px; }
_x000D_
This will work 100% and will remove the padding from left and right. I hope this helps.
I had the same problem, my database log file size was about 39 gigabyte, and after shrinking (both database and files) it reduced to 37 gigabyte that was not enough, so I did this solution: (I did not need the ldf file (log file) anymore)
(**Important) : Get a full backup of your database before the process.
Run "checkpoint" on that database.
Detach that database (right click on the database and chose tasks >> Detach...) {if you see an error, do the steps in the end of this text}
Move MyDatabase.ldf to another folder, you can find it in your hard disk in the same folder as your database (Just in case you need it in the future for some reason such as what user did some task).
Attach the database (right click on Databases and chose Attach...)
On attach dialog remove the .ldf file (which shows 'file not found' comment) and click Ok. (don`t worry the ldf file will be created after the attachment process.)
After that, a new log file create with a size of 504 KB!!!.
In step 2, if you faced an error that database is used by another user, you can:
1.run this command on master database "sp_who2" and see what process using your database.
2.read the process number, for example it is 52 and type "kill 52", now your database is free and ready to detach.
If the number of processes using your database is too much:
1.Open services (type services in windows start) find SQL Server ... process and reset it (right click and chose reset).
This was enough for me:
sudo apt-get install build-essential
Here is the simplest thing i could think of. Note that this program uses second command line argument (argv[1])
as a line to delete whitespaces from.
#include <string.h>
#include <stdio.h>
#include <stdlib.h>
/*The function itself with debug printing to help you trace through it.*/
char* trim(const char* str)
{
char* res = malloc(sizeof(str) + 1);
char* copy = malloc(sizeof(str) + 1);
copy = strncpy(copy, str, strlen(str) + 1);
int index = 0;
for (int i = 0; i < strlen(copy) + 1; i++) {
if (copy[i] != ' ')
{
res[index] = copy[i];
index++;
}
printf("End of iteration %d\n", i);
printf("Here is the initial line: %s\n", copy);
printf("Here is the resulting line: %s\n", res);
printf("\n");
}
return res;
}
int main(int argc, char* argv[])
{
//trim function test
const char* line = argv[1];
printf("Here is the line: %s\n", line);
char* res = malloc(sizeof(line) + 1);
res = trim(line);
printf("\nAnd here is the formatted line: %s\n", res);
return 0;
}

All the other answers here explain how to program your proxy settings into Firefox which is what WPAD was invented to do. If you have WPAD configured then just tell Firefox to use it to auto-detect its settings, as you would in the GUI.
To do this from a cmd file or command line:
pushd "%APPDATA%\Mozilla\Firefox\Profiles\*.default"
echo user_pref("network.proxy.type", 4);>>prefs.js
popd
This of course requires you to have WPAD configured and working correctly. Also I believe prefs.js
won't exist until you've run Firefox once.
In my own case I have the following error
Illegal mix of collations (utf8_general_ci,IMPLICIT) and (utf8_unicode_ci,IMPLICIT) for operation '='
$this->db->select("users.username as matric_no, CONCAT(users.surname, ' ', users.first_name, ' ', users.last_name) as fullname") ->join('users', 'users.username=classroom_students.matric_no', 'left') ->where('classroom_students.session_id', $session) ->where('classroom_students.level_id', $level) ->where('classroom_students.dept_id', $dept);
After weeks of google searching I noticed that the two fields I am comparing consists of different collation name. The first one i.e username is of utf8_general_ci while the second one is of utf8_unicode_ci so I went back to the structure of the second table and changed the second field (matric_no) to utf8_general_ci and it worked like a charm.
I know this is old, but none of these answers solved the root problem of numpy not saving the array row-wise. I found that this one liner did the trick for me:
b = np.matrix(a)
np.savetxt("file", b)
You can use store
object that is returned from createStore
function (which should be already used in your code in app initialization). Than you can use this object to get current state with store.getState()
method or store.subscribe(listener)
to subscribe to store updates.
You can even save this object to window
property to access it from any part of application if you really want it (window.store = store
)
More info can be found in the Redux documentation .
Here is how you can do it in Swift:

I'm using @fefe's excellent answer here to show how to fix this problem within some minutes when using docker (via docker-compose). It's quite easy as you don't have to touch MySQL's configuration files, but it requires you to export and import your entire data:
The default situation of your MySQL setup probably looks like this. Your data is saved inside the data-mysql
volume.
mysql:
image: mysql:5.7.25
container_name: mysql
restart: always
volumes:
- data-mysql:/var/lib/mysql
environment:
- "MYSQL_DATABASE=XXX"
- "MYSQL_USER=XXX"
- "MYSQL_PASSWORD=XXX"
- "MYSQL_ROOT_PASSWORD=XXX"
expose:
- 3306
Make a backup of your entire data/database via SQL export, so you have a .sql.gz or something. I'm using Adminer for this.
To fix (and as explained in @fefe's answer) we have to setup the MySQL instance from zero, meaning we have to delete the mysql docker container and the mysql volume docker container. Do a docker container ls
and a docker volume ls
to see all your containers and volumes, and pick the two names that are your mysql instance and your mysql volume, for me it's mysql
(container) and docker_data-mysql
(volume).
Stop your running instances via docker-compose down
(or however you usually stop your docker stuff).
To delete them, I do docker container rm mysql
and docker volume rm docker_data-mysql
(note that there is an underscore AND a dash in the name).
Add these settings to your mysql block in your docker setup:
mysql:
image: mysql:5.7.25
command: ['--innodb_page_size=64k', '--innodb_log_buffer_size=32M', '--innodb_buffer_pool_size=512M']
container_name: mysql
# ...
Restart your instances, the mysql and mysql volume should be build automatically, now with the new settings.
Import your database dump file, maybe with:
gzip -dc < database.sql.gz | docker exec -i mysql mysql -uroot -pYOURPASSWORD
Voila! Worked very fine for me!
I agree with the sentiment in "don't use magic values". But I would like to point out that there are times when it's legit to resort to such solutions.
There is a price to pay for setting columns nullable: NULLs are not indexable. A query like "get all records that haven't been modified since the start of 2010" includes those that have never been modified. If we use a nullable column we're thus forced to use [modified] < @cutoffDate OR [modified] IS NULL, and this in turn forces the database engine to perform a table scan, since the nulls are not indexed. And this last can be a problem.
In practice, one should go with NULL if this does not introduce a practical, real-world performance penalty. But it can be difficult to know, unless you have some idea what realistic data volumes are today and will be in the so-called forseeable future. You also need to know if there will be a large proportion of the records that have the special value - if so, there's no point in indexing it anyway.
In short, by deafult/rule of thumb one should go for NULL. But if there's a huge number of records, the data is frequently queried, and only a small proportion of the records have the NULL/special value, there could be significant performance gain for locating records based on this information (provided of course one creates the index!) and IMHO this can at times justify the use of "magic" values.
{% for days in days_list %}
<h2># Day {{ forloop.counter }} - From {{ days.from_location }} to {{ days.to_location }}</h2>
{% endfor %}
or if you want to start from 0
{% for days in days_list %}
<h2># Day {{ forloop.counter0 }} - From {{ days.from_location }} to {{ days.to_location }}</h2>
{% endfor %}
I don't know if this has changed. But from my experience. nested elements have a maximum opacity equal to the fathers.
Which mean:
<div id="a">
<div id="b">
</div></div>
Div#a has 0.6 opacity
div#b has 1 opacity
Has #b is within #a then it's maximum opacity is always 0.6
If #b would have 0.5 opacity. In reallity it would be 0.6*0.5 == 0.3 opacity
I had the same problem and i fixed it by checking what version pip (pip3 --version
) is, then realizing I'm typing python<uncorrect version> filename.py
instead of python<correct version> filename.py
You can set the line-height
in pixels instead of percentage. Is that what you mean?
It seems that you have forgotten to add your state server address in the config file.
<sessionstate mode="StateServer" timeout="20" server="127.0.0.1" port="42424" />
You can simply use the zoom property:
#myContainer{
zoom: 0.5;
-moz-transform: scale(0.5);
}
Where myContainer contains all the elements you're editing. This is supported in all major browsers.
I agree with @Mahomedalid's answer, but I didn't want to do something like a prepared statement and I didn't want to type all the fields, so what I had was a silly solution.
Go to the table in phpmyadmin->sql->select, it dumps the query: copy, replace and done! :)
An anonymous class is an inner class and the strict rule applies to inner classes (JLS 8.1.3):
Any local variable, formal method parameter or exception handler parameter used but not declared in an inner class must be declared final. Any local variable, used but not declared in an inner class must be definitely assigned before the body of the inner class.
I haven't found a reason or an explanation on the jls or jvms yet, but we do know, that the compiler creates a separate class file for each inner class and it has to make sure, that the methods declared on this class file (on byte code level) at least have access to the values of local variables.
(Jon has the complete answer - I keep this one undeleted because one might interested in the JLS rule)
Here is a rough explanation of the concepts.
[ACK]
is the acknowledgement that the previously sent data packet was received.
[FIN]
is sent by a host when it wants to terminate the connection; the TCP protocol requires both endpoints to send the termination request (i.e. FIN
).
So, suppose
[FIN,ACK]
indicating that it received the sent packet and wants to close the session.[FIN,ACK]
indicating that it received the termination request (the ACK
part) and that it too will close the connection (the FIN
part).However, if host A wants to close the session after sending the packet, it would only send a [FIN]
packet (nothing to acknowledge) but host B would respond with [FIN,ACK]
(acknowledges the request and responds with FIN
).
Finally, some TCP stacks perform half-duplex termination, meaning that they can send [RST]
instead of the usual [FIN,ACK]
. This happens when the host actively closes the session without processing all the data that was sent to it. Linux is one operating system which does just this.
You can find a more detailed and comprehensive explanation here.
You should use something like this:
<div style="text-align:center">
<input type="submit" />
</div>
Or you could use something like this. By giving the element a width and specifying auto
for the left and right margins the element will center itself in its parent.
<input type="submit" style="width: 300px; margin: 0 auto;" />
If you want to completely destroy the target, you have a couple of options. First you can remove the object from the DOM as described above...
console.log($target); // jQuery object
$target.remove(); // remove target from the DOM
console.log($target); // $target still exists
Option 1 - Then replace target with an empty jQuery object (jQuery 1.4+)
$target = $();
console.log($target); // empty jQuery object
Option 2 - Or delete the property entirely (will cause an error if you reference it elsewhere)
delete $target;
console.log($target); // error: $target is not defined

I think you need to use the notifications that are provided about the keyboard:
Keyboard Notifications
When the system shows or hides the keyboard, it posts several keyboard notifications. These notifications contain information about the keyboard, including its size, which you can use for calculations that involve moving views. Registering for these notifications is the only way to get some types of information about the keyboard. The system delivers the following notifications for keyboard-related events:
* UIKeyboardWillShowNotification * UIKeyboardDidShowNotification * UIKeyboardWillHideNotification * UIKeyboardDidHideNotification
For more information about these notifications, see their descriptions in UIWindow Class Reference. For information about how to show and hide the keyboard, see Text and Web.
Three simple choices.
Obvious
x, _ = func()
x, junk = func()
Hideous
x = func()[0]
And there are ways to do this with a decorator.
def val0( aFunc ):
def pick0( *args, **kw ):
return aFunc(*args,**kw)[0]
return pick0
func0= val0(func)
The simplest and most fun way (imo) is glob
foreach (glob("*.*") as $filename) {
echo $filename."<br />";
}
But the standard way is to use the directory functions.
if (is_dir($dir)) {
if ($dh = opendir($dir)) {
while (($file = readdir($dh)) !== false) {
echo "filename: .".$file."<br />";
}
closedir($dh);
}
}
There are also the SPL DirectoryIterator methods. If you are interested

I faced a similar kind of issue where my task was to push a message to SQS within a particular timeout. I used the trivial logic of executing it via another thread and waiting on its future object by specifying the timeout. This would give me a TIMEOUT exception in case of timeouts.
final Future<ISendMessageResult> future =
timeoutHelperThreadPool.getExecutor().submit(() -> {
return getQueueStore().sendMessage(request).get();
});
try {
sendMessageResult = future.get(200, TimeUnit.MILLISECONDS);
logger.info("SQS_PUSH_SUCCESSFUL");
return true;
} catch (final TimeoutException e) {
logger.error("SQS_PUSH_TIMEOUT_EXCEPTION");
}
But there are cases where you can't stop the code being executed by another thread and you get true negatives in that case.
For example - In my case, my request reached SQS and while the message was being pushed, my code logic encountered the specified timeout. Now in reality my message was pushed into the Queue but my main thread assumed it to be failed because of the TIMEOUT exception. This is a type of problem which can be avoided rather than being solved. Like in my case I avoided it by providing a timeout which would suffice in nearly all of the cases.
If the code you want to interrupt is within you application and is not something like an API call then you can simply use
future.cancel(true)
However do remember that java docs says that it does guarantee that the execution will be blocked.
"Attempts to cancel execution of this task. This attempt will fail if the task has already completed, has already been cancelled,or could not be cancelled for some other reason. If successful,and this task has not started when cancel is called,this task should never run. If the task has already started,then the mayInterruptIfRunning parameter determines whether the thread executing this task should be interrupted inan attempt to stop the task."

This might be too late to share, but I have something to contribute which might help someone, I was trying to sub-class the UINavigationBar and wanted to make it look like ios 6 with black status bar and status bar text in white.
Here is what I found working for that
self.navigationController?.navigationBar.clipsToBounds = true
self.navigationController?.navigationBar.translucent = false
self.navigationController?.navigationBar.barStyle = .Black
self.navigationController?.navigationBar.barTintColor = UIColor.whiteColor()
It made my status bar background black, status bar text white and navigation bar's color white.

Converting an int to a byte in Python 3:
n = 5
bytes( [n] )
>>> b'\x05'
;) guess that'll be better than messing around with strings
source: http://docs.python.org/3/library/stdtypes.html#binaryseq
Try this in the console:
var div = document.createElement('div');
div.setAttribute('onclick', 'alert(event)');
div.onclick
In Chrome, it shows this:
function onclick(event) {
alert(event)
}
...and the non-standard name
property of div.onclick
is "onclick"
.
So, whether or not this is anonymous depends your definition of "anonymous." Compare with something like var foo = new Function()
, where foo.name
is an empty string, and foo.toString()
will produce something like
function anonymous() {
}
For the benefit of Linux users who find themselves here: I found /etc/sysconfig/jenkins has a JENKINS_PORT="8080", which you should probably change too.
First click once on your package and then click setting icon on Android Studio.
Close/Unselect Compact Empty Middle Packages
Then, right click your package and rename it.
Thats all.
You should execute the next query:
GRANT ALL ON TABLE mytable TO myuser;
Or if your error is in a view then maybe the table does not have permission, so you should execute the next query:
GRANT ALL ON TABLE tbm_grupo TO myuser;
If somebody, who is looking for a solution in Swift, landed here, it would be:
myButton.isEnabled = false // disables
myButton.setTitle("myTitle", for: .normal) // sets text
Documentation: isEnabled, setTitle.
Older code:
myButton.enabled = false // disables
myButton.setTitle("myTitle", forState: UIControlState.Normal) // sets text
Public Function getWholeNumber(number As Decimal) As Integer
Dim round = Math.Round(number, 0)
If round > number Then
Return round - 1
Else
Return round
End If
End Function
In my case, nginx was not able to open the log file which is located here /var/log/nginx/error.log
This was because I had deleted the log directory to free up space in root (which turned out to be stupid)
I then created a log folder in var and an nginx folder in log.
Then simply run sudo service nginx start
Do you want an 'int' that looks like 20110425171213? In which case you'd be better off ToString with the appropriate format (something like 'yyyyMMddHHmmss') and then casting the string to an integer (or a long, unsigned int as it will be way more than 32 bits).
If you want an actual numeric value (the number of seconds since the year 0) then that's a very different calculation, e.g.
result = second
result += minute * 60
result += hour * 60 * 60
result += day * 60 * 60 * 24
etc.
But you'd be better off using Ticks.
I wrote a JavaScript analogue of a PHP function number_format on a base of Abe Miessler addCommas function. Could be usefull.
number_format = function (number, decimals, dec_point, thousands_sep) {
number = number.toFixed(decimals);
var nstr = number.toString();
nstr += '';
x = nstr.split('.');
x1 = x[0];
x2 = x.length > 1 ? dec_point + x[1] : '';
var rgx = /(\d+)(\d{3})/;
while (rgx.test(x1))
x1 = x1.replace(rgx, '$1' + thousands_sep + '$2');
return x1 + x2;
}
For example:
var some_number = number_format(42661.55556, 2, ',', ' '); //gives 42 661,56
With Bootstrap 4, there is a css class specifically for this. The below will center row content:
<div class="row justify-content-center">
...inner divs and content...
</div>
See: https://v4-alpha.getbootstrap.com/layout/grid/#horizontal-alignment, for more information.
You got half of the answer! Now that you created the event handler, you need to hook it to the form so that it actually gets called when the form is loading. You can achieve that by doing the following:
public class ProgramViwer : Form{
public ProgramViwer()
{
InitializeComponent();
Load += new EventHandler(ProgramViwer_Load);
}
private void ProgramViwer_Load(object sender, System.EventArgs e)
{
formPanel.Controls.Clear();
formPanel.Controls.Add(wel);
}
}
Use these lines in the code, because the textEntryView is the parent of username edittext and password edittext.
final EditText input1 = (EditText) textEntryView .findViewById(R.id.username);
final EditText input2 = (EditText) textEntryView .findViewById(R.id.password);
Maybe you can try this: though please note - This pulls the column count, not the row count
using (SqlDataReader reader = command.ExecuteReader())
{
while (reader.Read())
{
int count = reader.VisibleFieldCount;
Console.WriteLine(count);
}
}
After gone throug the various post, this worked fine for me doing on IntelliJ Idea
:
java -cp "./lib/*;Path to your test.class" org.testng.TestNG testng.xml
Here is my directory structure:
/lib
-- all jar including testng.jar
/out
--/production/Example1/test.class
/src
-- test.java
testing.xml
So execute by this command:
java -cp "./lib/*;C:\Users\xyz\IdeaProjects\Example1\out\production\Example1" org.testng.TestNG testng.xml
My project directory Example1
is in the path:
C:\Users\xyz\IdeaProjects\
This is because your Page2
class doesn't have a companion object which is similar to static
in Java so to use your class. To pass your class as an argument to Intent
, you will have to do something like this
val changePage = Intent(this, Page2::class.java)
The following requires you to list the keys on your own, but at least TypeScript will enforce IUserProfile
and IUserProfileKeys
have the exact same keys (Required<T>
was added in TypeScript 2.8):
export interface IUserProfile {
id: string;
name: string;
};
type KeysEnum<T> = { [P in keyof Required<T>]: true };
const IUserProfileKeys: KeysEnum<IUserProfile> = {
id: true,
name: true,
};
The following worked really well for me. I needed to redraw the datatable with a different subset of the data based on a parameter.
table.ajax.url('NewDataUrl?parameter=' + param).load();
If your data is static, then use this:
table.ajax.url('NewDataUrl').load();
Check the link Regular Expression Demo
use the below reg exp
[a-z] + [^0-9\s.]+|.(?!\d)
I had the same problem in iOS, using the onChangeText event to update the value of the text typed by the user I was not being able to update the value of the TextInput, so the user would still see the non numeric characters that he typed.
This was because, when a non numeric character was pressed the state would not change since this.setState would be using the same number (the number that remained after removing the non numeric characters) and then the TextInput would not re render.
The only way I found to solve this was to use the keyPress event which happens before the onChangeText event, and in it, use setState to change the value of the state to another, completely different, forcing the re render when the onChangeText event was called. Not very happy with this but it worked.

dataGridView1.Rows[dataGridView1.CurrentCell.RowIndex].Selected = true;
break;
}
}
}

css
has variables as well. You can use them like this:
--primaryColor: #ffffff;
--width: 800px;
body {
width: var(--width);
color: var(--primaryColor);
}
.content{
width: var(--width);
background: var(--primaryColor);
}
When you are manipulating the DOM with jquery the methods you use depend on the result you want and a frequent use is to replace content.
In replacing content you want to .remove()
the content and replace it with new content. If you .remove()
the existing tag and then try to use .append()
it won't work because the tag itself has been removed, whereas if you use .after()
, the new content is added 'outside' the (now removed) tag and isn't affected by the previous .remove()
.
Bill Horst's - Converting SQL to LINQ is a very good resource for this task (as well as LINQPad).
LINQ Tools has a decent list of tools as well but I do not believe there is anything else out there that can do what Linqer did.
Generally speaking, LINQ is a higher-level querying language than SQL which can cause translation loss when trying to convert SQL to LINQ. For one, LINQ emits shaped results and SQL flat result sets. The issue here is that an automatic translation from SQL to LINQ will often have to perform more transliteration than translation - generating examples of how NOT to write LINQ queries. For this reason, there are few (if any) tools that will be able to reliably convert SQL to LINQ. Analogous to learning C# 4 by first converting VB6 to C# 4 and then studying the resulting conversion.
Don't forget: to get HTTPS contents, your OPENSSL extension should be enabled in your php.ini. (how to get contents of site use HTTPS)

As Inian suggested, you should alias python to point to python 3. It is very easy to do, and very easy to switchback, personally i have an alias setup for p2=python2 and p3=python3 as well to save on keystrokes. Read here for more information: How do I create a Bash alias?
Here is an example of doing so for python:
alias python=python3
Like so:
$ python --version
Python 2.7.6
$ python3 --version
Python 3.4.3
$ alias python=python3
$ python --version
Python 3.4.3

The two calls have different meanings that have nothing to do with performance; the fact that it speeds up the execution time is (or might be) just a side effect. You should understand what each of them does and not blindly include them in every program because they look like an optimization.
ios_base::sync_with_stdio(false);
This disables the synchronization between the C and C++ standard streams. By default, all standard streams are synchronized, which in practice allows you to mix C- and C++-style I/O and get sensible and expected results. If you disable the synchronization, then C++ streams are allowed to have their own independent buffers, which makes mixing C- and C++-style I/O an adventure.
Also keep in mind that synchronized C++ streams are thread-safe (output from different threads may interleave, but you get no data races).
cin.tie(NULL);
This unties cin
from cout
. Tied streams ensure that one stream is flushed automatically before each I/O operation on the other stream.
By default cin
is tied to cout
to ensure a sensible user interaction. For example:
std::cout << "Enter name:";
std::cin >> name;
If cin
and cout
are tied, you can expect the output to be flushed (i.e., visible on the console) before the program prompts input from the user. If you untie the streams, the program might block waiting for the user to enter their name but the "Enter name" message is not yet visible (because cout
is buffered by default, output is flushed/displayed on the console only on demand or when the buffer is full).
So if you untie cin
from cout
, you must make sure to flush cout
manually every time you want to display something before expecting input on cin
.
In conclusion, know what each of them does, understand the consequences, and then decide if you really want or need the possible side effect of speed improvement.
Use flush when you need to write, for example to get a primary key ID from an autoincrementing counter.
john=Person(name='John Smith', parent=None)
session.add(john)
session.flush()
son=Person(name='Bill Smith', parent=john.id)
Without flushing, john would never get an ID from the DB and so couldn't represent the parent/child relationship in code.
Like others have said, without commit()
none of this will be permanently persisted to DB.
In case if you are not aware of the number and name of columns in dataframe then this method can be handy:
column_list = []
df_column = pd.read_excel(file_name, 'Sheet1').columns
for i in df_column:
column_list.append(i)
converter = {col: str for col in column_list}
df_actual = pd.read_excel(file_name, converters=converter)
where column_list is the list of your column names.

imho there are two cases for branches that were forgot to close
Case 1: branch was not merged into default
in this case I update to the branch and do another commit with --close-branch, unfortunatly this elects the branch to become the new tip and hence before pushing it to other clones I make sure that the real tip receives some more changes and others don't get confused about that strange tip.
hg up myBranch
hg commit --close-branch
Case 2: branch was merged into default
This case is not that much different from case 1 and it can be solved by reproducing the steps for case 1 and two additional ones.
in this case I update to the branch changeset, do another commit with --close-branch and merge the new changeset that became the tip into default. the last operation creates a new tip that is in the default branch - HOORAY!
hg up myBranch
hg commit --close-branch
hg up default
hg merge myBranch
Hope this helps future readers.
While this is one of the most voted feature requests, there is one plugin available, by Victor Kropp, that adds support to makefiles:

There are at least three different ways to run:
It opens a pane named Run target with the output.
Use -S option in the sudo command which tells to read the password from 'stdin' instead of the terminal device.
Tell Popen to read stdin from PIPE.
Send the Password to the stdin PIPE of the process by using it as an argument to communicate method. Do not forget to add a new line character, '\n', at the end of the password.
sp = Popen(cmd , shell=True, stdin=PIPE)
out, err = sp.communicate(_user_pass+'\n')
I had the exact same issue where jquery ajax only gave me cors issues on post requests where get requests worked fine - I tired everything above with no results. I had the correct headers in my server etc. Changing over to use XMLHTTPRequest instead of jquery fixed my issue immediately. No matter which version of jquery I used it didn't fix it. Fetch also works without issues if you don't need backward browser compatibility.
var xhr = new XMLHttpRequest()
xhr.open('POST', 'https://mywebsite.com', true)
xhr.withCredentials = true
xhr.onreadystatechange = function() {
if (xhr.readyState === 2) {// do something}
}
xhr.setRequestHeader('Content-Type', 'application/json')
xhr.send(json)
Hopefully this helps anyone else with the same issues.
I think there is no fixed way to solve this problem since it might be caused by different reason. I also had this problem last week, I don't know when and exactly what cause this problem, only when I run it on simulator with Xcode or try to install it onto the phone, then it reports such kind of error, But when I run it with react-native run-ios with terminal, there is no problem.
I checked all the ways posted on the internet, like renew certificate, change settings in Xcode (all of ways mentions above), actually all of settings in Xcode were already set as it requested before, none of ways works for me. Until this morning when I delete the pods and reinstall, the error finally gonna after a week. If you are also using cocoapod and then error was just show up without any specific reason, maybe you can try my way.
Underscore and Lodash have the _.last(Array)
method, that returns the last element in an Array. They both work about the same
_.last([5, 4, 3, 2, 1]);
=> 1
Ramda also has a _.last
function
R.last(['fi', 'fo', 'fum']); //=> 'fum'
The primary flag seems to only work for vagrant ssh
for me.
In the past I have used the following method to hack around the issue.
# stage box intended for configuration closely matching production if ARGV[1] == 'stage' config.vm.define "stage" do |stage| box_setup stage, \ "10.9.8.31", "deploy/playbook_full_stack.yml", "deploy/hosts/vagrant_stage.yml" end end
Change return false;
to return true;
in longClickListener
You long click the button, if it returns true then it does the work. If it returns false then it does it's work and also calls the short click and then the onClick also works.
If you're using JQuery you can do:
$('#elementid').click();
You might want to look at the RouteLink()
method.That one lets you specify everything (except the link text and route name) via a dictionary.
try this it worked for me in ie 7 and ie 8
$(this).click(function (j) {
var href = ($(this).attr('href'));

I tried other answers on this question, and there are mistakes with the different browser APIs, particularly Fullscreen

let doc=document,elm=doc.documentElement;
if (elm.requestFullscreen ) { (!doc.fullscreenElement ? elm.requestFullscreen() : doc.exitFullscreen() ) }
else if (elm.mozRequestFullScreen ) { (!doc.mozFullScreen ? elm.mozRequestFullScreen() : doc.mozCancelFullScreen() ) }

With SQL Server 2012 and onward you can use the FORMAT
function
SELECT FORMAT(GETDATE(), 'dddd')
char c = '5'
A char
(1 byte) is allocated on stack at address 0x12345678
.
char *d = &c;
You obtain the address of c
and store it in d
, so d = 0x12345678
.
int *e = (int*)d;
You force the compiler to assume that 0x12345678
points to an int
, but an int is not just one byte (sizeof(char) != sizeof(int)
). It may be 4 or 8 bytes according to the architecture or even other values.
So when you print the value of the pointer, the integer is considered by taking the first byte (that was c
) and other consecutive bytes which are on stack and that are just garbage for your intent.

Remenber to add the using libs!
You can use the util library that comes with nodejs to get a promise from the exec command and can use that output as you need. Use restructuring to store the stdout and stderr in variables.
const util = require('util');
const exec = util.promisify(require('child_process').exec);
async function lsExample() {
const {
stdout,
stderr
} = await exec('ls');
console.log('stdout:', stdout);
console.error('stderr:', stderr);
}

Fist of all:
I believe that you are mixing up the MVC pattern and n-tier-based design principles.
Using an MVC approach does not mean that you shouldn't layer your application.
It might help if you see MVC more like an extension of the presentation layer.
If you put non-presentation code inside the MVC pattern you might very soon end up in a complicated design.
Therefore I would suggest that you put your business logic into a separate business layer.
Just have a look at this: Wikipedia article about multitier architecture
It says:
Today, MVC and similar model-view-presenter (MVP) are Separation of Concerns design patterns that apply exclusively to the presentation layer of a larger system.
Anyway ... when talking about an enterprise web application the calls from the UI to the business logic layer should be placed inside the (presentation) controller.
That is because the controller actually handles the calls to a specific resource, queries the data by making calls to the business logic and links the data (model) to the appropriate view.
Mud told you that the business rules go into the model.
That is also true, but he mixed up the (presentation) model (the 'M' in MVC) and the data layer model of a tier-based application design.
So it is valid to place your database related business rules in the model (data layer) of your application.
But you should not place them in the model of your MVC-structured presentation layer as this only applies to a specific UI.
This technique is independent of whether you use a domain driven design or a transaction script based approach.
Let me visualize that for you:
Presentation layer: Model - View - Controller
Business layer: Domain logic - Application logic
Data layer: Data repositories - Data access layer
The model that you see above means that you have an application that uses MVC, DDD and a database-independed data layer.
This is a common approach to design a larger enterprise web application.
But you can also shrink it down to use a simple non-DDD business layer (a business layer without domain logic) and a simple data layer that writes directly to a specific database.
You could even drop the whole data-layer and access the database directly from the business layer, though I do not recommend it.
Thats' the trick...I hope this helps...
[Note:] You should also be aware of the fact that nowadays there is more than just one "model" in an application. Commonly, each layer of an application has it's own model. The model of the presentation layer is view specific but often independent of the used controls. The business layer can also have a model, called the "domain-model". This is typically the case when you decide to take a domain-driven approach. This "domain-model" contains of data as well as business logic (the main logic of your program) and is usually independent of the presentation layer. The presentation layer usually calls the business layer on a certain "event" (button pressed etc.) to read data from or write data to the data layer. The data layer might also have it's own model, which is typically database related. It often contains a set of entity classes as well as data-access-objects (DAOs).
The question is: how does this fit into the MVC concept?
Answer -> It doesn't!
Well - it kinda does, but not completely.
This is because MVC is an approach that was developed in the late 1970's for the Smalltalk-80 programming language. At that time GUIs and personal computers were quite uncommon and the world wide web was not even invented!
Most of today's programming languages and IDEs were developed in the 1990s.
At that time computers and user interfaces were completely different from those in the 1970s.
You should keep that in mind when you talk about MVC.
Martin Fowler has written a very good article about MVC, MVP and today's GUIs.
As Brad Wilson states in his answer here:
ModelState.IsValid tells you if any model errors have been added to ModelState.
The default model binder will add some errors for basic type conversion issues (for example, passing a non-number for something which is an "int"). You can populate ModelState more fully based on whatever validation system you're using.
Try using :-
if (!ModelState.IsValid)
{
var errors = ModelState.SelectMany(x => x.Value.Errors.Select(z => z.Exception));
// Breakpoint, Log or examine the list with Exceptions.
}
If it helps catching you the error. Courtesy this and this
You should use Handler
's postDelayed
function for this purpose. It will run your code with specified delay on the main UI thread, so you will be able to update UI controls.
private int mInterval = 5000; // 5 seconds by default, can be changed later
private Handler mHandler;
@Override
protected void onCreate(Bundle bundle) {
// your code here
mHandler = new Handler();
startRepeatingTask();
}
@Override
public void onDestroy() {
super.onDestroy();
stopRepeatingTask();
}
Runnable mStatusChecker = new Runnable() {
@Override
public void run() {
try {
updateStatus(); //this function can change value of mInterval.
} finally {
// 100% guarantee that this always happens, even if
// your update method throws an exception
mHandler.postDelayed(mStatusChecker, mInterval);
}
}
};
void startRepeatingTask() {
mStatusChecker.run();
}
void stopRepeatingTask() {
mHandler.removeCallbacks(mStatusChecker);
}
As mentioned by @PSIXO in a comment, this might be the problem with the dependency version of google-services. For me changing,
buildscript {
// ...
dependencies {
// ...
classpath 'com.google.gms:google-services:4.1.0'
}
}
to
buildscript {
// ...
dependencies {
// ...
classpath 'com.google.gms:google-services:4.0.1'
}
}
worked.There might be some problem with 4.1.0 version. Because I wasted many hours on this, I thought to write this as an answer.
Try this one with array_reverse()
.
$arr = array(
'first' => 01,
'second' => 10,
'third' => 20,
);
$key = key(array_reverse($arr));
var_dump($key);
Try moving the lapsList
function out of your class and into your render function:
render() {
const lapsList = this.state.laps.map((data) => {
return (
<View><Text>{data.time}</Text></View>
)
})
return (
<View style={styles.container}>
<View style={styles.footer}>
<View><Text>coucou test</Text></View>
{lapsList}
</View>
</View>
)
}

The Keystore itself is encrypted using the user’s own lockscreen pin/password, hence, when the device screen is locked the Keystore is unavailable. Keep this in mind if you have a background service that could need to access your application secrets.

The File
class represents the "idea" of a file, not an actual handle to use for I/O. This is why the File
class has a .exists()
method, to tell you if the file exists or not. (How can you have a File
object that doesn't exist?)
By contrast, constructing a new FileInputStream(new File("/my/file"))
gives you an actual stream to read bytes from.
int arr[] = { 12, 13, 54, 16, 25, 8, 78 };
for (int i = 0; i < arr.length; i++) {
Arrays.sort(arr);
System.out.println(arr[i]);
}
I just created this and it looks easier. You get these 2 functions:
=GetColorIndex(E5) <- returns color number for the cell
from (cell)
=CountColorIndexInRange(C7:C24,14) <- returns count of cells C7:C24 with color 14
from (range of cells, color number you want to count)
example shows percent of cells with color 14
=ROUND(CountColorIndexInRange(C7:C24,14)/18, 4 )
Create these 2 VBA functions in a Module (hit Alt-F11)
open + folders. double-click on Module1
Just paste this text below in, then close the module window (it must save it then):
Function GetColorIndex(Cell As Range)
GetColorIndex = Cell.Interior.ColorIndex
End Function
Function CountColorIndexInRange(Rng As Range, TestColor As Long)
Dim cnt
Dim cl As Range
cnt = 0
For Each cl In Rng
If GetColorIndex(cl) = TestColor Then
Rem Debug.Print ">" & TestColor & "<"
cnt = cnt + 1
End If
Next
CountColorIndexInRange = cnt
End Function
Beware of recipes like this
target:
MY_ID=$(GENERATE_ID);
echo $MY_ID;
It does two things wrong. The first line in the recipe is executed in a separate shell instance from the second line. The variable is lost in the meantime. Second thing wrong is that the $
is not escaped.
target:
MY_ID=$(GENERATE_ID); \
echo $$MY_ID;
Both problems have been fixed and the variable is useable. The backslash combines both lines to run in one single shell, hence the setting of the variable and the reading of the variable afterwords, works.
I realize the original post said how to get the results of a shell command into a MAKE variable, and this answer shows how to get it into a shell variable. But other readers may benefit.
One final improvement, if the consumer expects an "environment variable" to be set, then you have to export it.
my_shell_script
echo $MY_ID
would need this in the makefile
target:
export MY_ID=$(GENERATE_ID); \
./my_shell_script;
Hope that helps someone. In general, one should avoid doing any real work outside of recipes, because if someone use the makefile with '--dry-run' option, to only SEE what it will do, it won't have any undesirable side effects. Every $(shell)
call is evaluated at compile time and some real work could accidentally be done. Better to leave the real work, like generating ids, to the inside of the recipes when possible.
I had the same problem. I solve it when I convert string to factor. In your case, check the class of variable and check if they are numeric and 'train and test' should be factor.
.project
When a project is created in the workspace, a project description file is automatically generated that describes the project. The sole purpose of this file is to make the project self-describing, so that a project that is zipped up or released to a server can be correctly recreated in another workspace.
.classpath
Classpath specifies which Java source files and resource files in a project are considered by the Java builder and specifies how to find types outside of the project. The Java builder compiles the Java source files into the output folder and also copies the resources into it.

Check the sorce code (HTML) of YouTube, you'll get the link like this (http%253A%252F%252Fo-o.preferred.telemar-cnf1.v18.lscache6.c.youtube.com%252Fvideoplayback ...);
Decode the url (remove the codes %2B,%25 etc), create a decoder with the codes: http://www.w3schools.com/tags/ref_urlencode.asp and use the function Uri.decode(url) to replace invalid escaped octets;
Use the code to download stream:
URL u = null;
InputStream is = null;
try {
u = new URL(url);
is = u.openStream();
HttpURLConnection huc = (HttpURLConnection)u.openConnection(); //to know the size of video
int size = huc.getContentLength();
if(huc != null) {
String fileName = "FILE.mp4";
String storagePath = Environment.getExternalStorageDirectory().toString();
File f = new File(storagePath,fileName);
FileOutputStream fos = new FileOutputStream(f);
byte[] buffer = new byte[1024];
int len1 = 0;
if(is != null) {
while ((len1 = is.read(buffer)) > 0) {
fos.write(buffer,0, len1);
}
}
if(fos != null) {
fos.close();
}
}
} catch (MalformedURLException mue) {
mue.printStackTrace();

After use codevar json = @Html.Raw(Json.Encode(@Model.CollegeInformationlist));
You need use JSON.parse(JSON.stringify(json))

None of the above examples worked for my personal needs. The below is what I ended up doing.
public class ContainsConstraint : IHttpRouteConstraint
{
public string[] array { get; set; }
public bool match { get; set; }
/// <summary>
/// Check if param contains any of values listed in array.
/// </summary>
/// <param name="param">The param to test.</param>
/// <param name="array">The items to compare against.</param>
/// <param name="match">Whether we are matching or NOT matching.</param>
public ContainsConstraint(string[] array, bool match)
{
this.array = array;
this.match = match;
}
public bool Match(System.Net.Http.HttpRequestMessage request, IHttpRoute route, string parameterName, IDictionary<string, object> values, HttpRouteDirection routeDirection)
{
if (values == null) // shouldn't ever hit this.
return true;
if (!values.ContainsKey(parameterName)) // make sure the parameter is there.
return true;
if (string.IsNullOrEmpty(values[parameterName].ToString())) // if the param key is empty in this case "action" add the method so it doesn't hit other methods like "GetStatus"
values[parameterName] = request.Method.ToString();
bool contains = array.Contains(values[parameterName]); // this is an extension but all we are doing here is check if string array contains value you can create exten like this or use LINQ or whatever u like.
if (contains == match) // checking if we want it to match or we don't want it to match
return true;
return false;
}
To use the above in your route use:
config.Routes.MapHttpRoute("Default", "{controller}/{action}/{id}", new { action = RouteParameter.Optional, id = RouteParameter.Optional}, new { action = new ContainsConstraint( new string[] { "GET", "PUT", "DELETE", "POST" }, true) });
What happens is the constraint kind of fakes in the method so that this route will only match the default GET, POST, PUT and DELETE methods. The "true" there says we want to check for a match of the items in array. If it were false you'd be saying exclude those in the strYou can then use routes above this default method like:
config.Routes.MapHttpRoute("GetStatus", "{controller}/status/{status}", new { action = "GetStatus" });
In the above it is essentially looking for the following URL => http://www.domain.com/Account/Status/Active
or something like that.
Beyond the above I'm not sure I'd get too crazy. At the end of the day it should be per resource. But I do see a need to map friendly urls for various reasons. I'm feeling pretty certain as Web Api evolves there will be some sort of provision. If time I'll build a more permanent solution and post.
Instead of thinking of it as 'extracting', I like to think of it as 'isolating'. Once the desired bits are isolated, you can do what you will with them.
To isolate any set of bits, apply an AND mask.
If you want the last X bits of a value, there is a simple trick that can be used.
unsigned mask;
mask = (1 << X) - 1;
lastXbits = value & mask;
If you want to isolate a run of X bits in the middle of 'value' starting at 'startBit' ...
unsigned mask;
mask = ((1 << X) - 1) << startBit;
isolatedXbits = value & mask;
Hope this helps.
Expanding on what Mark Elliot said earlier, the easiest way to get the size of a 2D array given that each array in the array of arrays is of the same size is:
array.length * array[0].length
This works for my Mac since High Sierra update.
Remove the group write access:
sudo chmod g-w /usr/local/share/zsh/site-functions
sudo chmod g-w /usr/local/share/zsh
It’s best to keep the change limited to zsh directories.
At last! I got the answer to this, the size to edit it in photoshop is: 379x674

If Linux is your concern, the easiest way to append two strings:
char * append(char * string1, char * string2)
{
char * result = NULL;
asprintf(&result, "%s%s", string1, string2);
return result;
}
This won't work with MS Visual C.
Note: you have to free()
the memory returned by asprintf()
I recommend using python-dateutil. Its parser has been able to parse every date format I've thrown at it so far.
>>> from dateutil import parser
>>> parser.parse("Tue Jun 22 07:46:22 EST 2010")
datetime.datetime(2010, 6, 22, 7, 46, 22, tzinfo=tzlocal())
>>> parser.parse("Fri, 11 Nov 2011 03:18:09 -0400")
datetime.datetime(2011, 11, 11, 3, 18, 9, tzinfo=tzoffset(None, -14400))
>>> parser.parse("Sun")
datetime.datetime(2011, 12, 18, 0, 0)
>>> parser.parse("10-11-08")
datetime.datetime(2008, 10, 11, 0, 0)
and so on. No dealing with strptime()
format nonsense... just throw a date at it and it Does The Right Thing.
Update: Oops. I missed in your original question that you mentioned that you used dateutil
, sorry about that. But I hope this answer is still useful to other people who stumble across this question when they have date parsing questions and see the utility of that module.
I had a similar warning/error/failure when I was simply trying to make an executable from two different object files (main.o and add.o). I was using the command:
gcc -o exec main.o add.o
But my program is a C++ program. Using the g++
compiler solved my issue:
g++ -o exec main.o add.o
I was always under the impression that gcc
could figure these things out on its own. Apparently not. I hope this helps someone else searching for this error.
If it's jQuery...

Given
std::vector<Rule>& topPriorityRules;
The correct way to remove the first element of the referenced vector is
topPriorityRules.erase(topPriorityRules.begin());
which is exactly what you suggested.
Looks like i need to do iterator overloading.
There is no need to overload an iterator in order to erase first element of std::vector
.
P.S. Vector (dynamic array) is probably a wrong choice of data structure if you intend to erase from the front.
I think TrungTN and anon's answer is okay, but MartinStettner's way of implementing the hex() function is not really simple, and too dark, considering hex << (int)mychar is already a workaround.
here is my solution to make "<<" operator easier:
#include <sstream>
#include <iomanip>
string uchar2hex(unsigned char inchar)
{
ostringstream oss (ostringstream::out);
oss << setw(2) << setfill('0') << hex << (int)(inchar);
return oss.str();
}
int main()
{
unsigned char a = 131;
std::cout << uchar2hex(a) << std::endl;
}
It's just not worthy implementing a stream operator :-)
Here's a quicker way than multi-layer menus without resorting to plug-ins:
Use the Quick Access tool at the upper left corner.
Type in "font", then, from the list that drops down, click on the link for "Preferences->Colors and Fonts->General->Appearance".
One click replaces the 4 needed to get there through menus. I do it so often, my Quick Access tool pulls it up as a previous choice right at the top of the list so I can just type "font" with a tap on the enter key and Boom!, I'm there.
If you want a keyboard shortcut, Ctrl+3 sets the focus to the Quick Access tool. Better yet, this even automatically brings up a list with your previous choices. The last one you chose will be on top, in which case a simple Ctrl+3 followed by enter would bring you straight there! I use this all the time to make it bigger during long typing or reading sessions to ease eye strain, or to make it smaller if I need more text on the screen at one time to make it easier to find something.
It's not quite as nice as zooming with the scroll wheel or with a simple Ctrl+ or Ctrl-, but it's a lot better than navigating through the menus every time!
I would wrap your rows in labels
<form action="doit" id="doit" method="post">
<label>
Name
<input id="name" name="name" type="text" />
</label>
<label>
Phone number
<input id="phone" name="phone" type="text" />
</label>
<label>
Year
<input id="year" name="year" type="text" />
</label>
</form>
And use
label, input {
display: block;
}
label {
margin-bottom: 20px;
}
Don't use br
s for spacing!
This works for basic expressions
const nameof = exp => exp.toString().match(/[.](\w+)/)[1];
Example
nameof(() => options.displaySize);
Snippet:
var nameof = function (exp) { return exp.toString().match(/[.](\w+)/)[1]; };_x000D_
var myFirstName = 'Chuck';_x000D_
var varname = nameof(function () { return window.myFirstName; });_x000D_
console.log(varname);
_x000D_
const path = require('path');
if (path.sep === "\\") {
console.log("Windows");
} else {
console.log("Not Windows");
}
Use str.replace
.
>>> papa.replace('papa', '')
' is a good man'
>>> app.replace('papa', '')
'app is important'
Alternatively use re
and use regular expressions. This will allow the removal of leading/trailing spaces.
>>> import re
>>> papa = 'papa is a good man'
>>> app = 'app is important'
>>> papa3 = 'papa is a papa, and papa'
>>>
>>> patt = re.compile('(\s*)papa(\s*)')
>>> patt.sub('\\1mama\\2', papa)
'mama is a good man'
>>> patt.sub('\\1mama\\2', papa3)
'mama is a mama, and mama'
>>> patt.sub('', papa3)
'is a, and'
You can save the struct into a map by matching the struct Key
and Value
components to their fictive key and value parts on the map:
mapConfig := map[string]string{}
for _, v := range myconfig {
mapConfig[v.Key] = v.Value
}
Then using the golang comma ok idiom you can test for the key presence:
if v, ok := mapConfig["key1"]; ok {
fmt.Printf("%s exists", v)
}
In standard C lua, no. You will have to settle for seconds, unless you are willing to modify the lua interpreter yourself to have os.time use the resolution you want. That may be unacceptable, however, if you are writing code for other people to run on their own and not something like a web application where you have full control of the environment.
Edit: another option is to write your own small DLL in C that extends lua with a new function that would give you the values you want, and require that dll be distributed with your code to whomever is going to be using it.
Changing the address's port number (localhost:) worked for me :)
If you want to apply some condition on form submit then you can use this method
<form onsubmit="return checkEmpData();" method="post" action="process.html">
<input type="text" border="0" name="submit" />
<button value="submit">submit</button>
</form>
One thing always keep in mind that method and action attribute write after onsubmit attributes
javascript code
function checkEmpData()
{
var a = 0;
if(a != 0)
{
return confirm("Do you want to generate attendance?");
}
else
{
alert('Please Select Employee First');
return false;
}
}
Add reference to Microsoft.VisualBasic
and use this function:
string response = Microsoft.VisualBasic.Interaction.InputBox("What's 1+1?", "Title", "2", 0, 0);
The last 2 number is an X/Y position to display the input dialog.
is
is generally preferred when comparing arbitrary objects to singletons like None
because it is faster and more predictable. is
always compares by object identity, whereas what ==
will do depends on the exact type of the operands and even on their ordering.
This recommendation is supported by PEP 8, which explicitly states that "comparisons to singletons like None should always be done with is
or is not
, never the equality operators."

When you call a class member, Python automatically uses a reference to the object as the first parameter. The variable self
actually means nothing, it's just a coding convention. You could call it gargaloo
if you wanted. That said, the call to method_two
would raise a TypeError
, because Python is automatically trying to pass a parameter (the reference to its parent object) to a method that was defined as having no parameters.
To actually make it work, you could append this to your class definition:
method_two = staticmethod(method_two)
or you could use the @staticmethod
function decorator.
You are wasting your time:
P1
name anyway.Just put all your functions in the .py
file:
# my_module.py
def f1():
pass
def f2():
pass
def f3():
pass
And use them like this:
import my_module
my_module.f1()
my_module.f2()
my_module.f3()
or:
from my_module import f1
from my_module import f2
from my_module import f3
f1()
f2()
f3()
This should be enough for starters.

If you don't want to install the cors library and instead want to fix your original code, the other step you are missing is that Access-Control-Allow-Origin:* is wrong. When passing Authentication tokens (e.g. JWT) then you must explicitly state every url that is calling your server. You can't use "*" when doing authentication tokens.
