Frames have been deprecated because they caused trouble for url navigation and hyperlinking, because the url would just take to you the index page (with the frameset) and there was no way to specify what was in each of the frame windows. Today, webpages are often generated by server-side technologies such as PHP, ASP.NET, Ruby etc. So instead of using frames, pages can simply be generated by merging a template with content like this:
Template File
<html>
<head>
<title>{insert script variable for title}</title>
</head>
<body>
<div class="menu">
{menu items inserted here by server-side scripting}
</div>
<div class="main-content">
{main content inserted here by server-side scripting}
</div>
</body>
</html>
If you don't have full support for a server-side scripting language, you could also use server-side includes (SSI). This will allow you to do the same thing--i.e. generate a single web page from multiple source documents.
But if you really just want to have a section of your webpage be a separate "window" into which you can load other webpages that are not necessarily located on your own server, you will have to use an iframe.
You could emulate your example like this:
Frames Example
<html>
<head>
<title>Frames Test</title>
<style>
.menu {
float:left;
width:20%;
height:80%;
}
.mainContent {
float:left;
width:75%;
height:80%;
}
</style>
</head>
<body>
<iframe class="menu" src="menu.html"></iframe>
<iframe class="mainContent" src="events.html"></iframe>
</body>
</html>
There are probably better ways to achieve the layout. I've used the CSS float attribute, but you could use tables or other methods as well.
You need to make sure the frame is fully loaded the best way to do it is to use onload:
<iframe id="nesgt" src="" onload="custom()"></iframe>
function custom(){
document.getElementById("nesgt").contentWindow.document;
}
this function will run automatically when the iframe is fully loaded.
it could be done with setTimeout but we can't get the exact time of the frame load.
hope this helps someone.
You can try also this:
pathinfo(basename($_FILES["fileToUpload"]["name"]), PATHINFO_EXTENSION)
Rather than using the jQuery .parents
function (as suggested in the accepted answer), it's better to use .closest
for this purpose. As explained in the jQuery api docs, .closest
checks the element passed and all its parents, whereas .parents
just checks the parents.
Consequently, this works:
$(function() {
$("body").click(function(e) {
if ($(e.target).closest("#myDiv").length) {
alert("Clicked inside #myDiv");
} else {
alert("Clicked outside #myDiv");
}
});
})
execCommand('SaveAs', false, filename);
functionalityEdit: No longer works. This Javascript function used to work across all browsers, but now only on IE, due to browser security considerations. It presented a "Save As" Dialog to the user who runs this function through their browser, the user presses OK and the file is saved by javascript on the server side.
Now this code is an rare antique zero day collectible.
// content is the data (a string) you'll write to file.
// filename is a string filename to write to on server side.
// This function uses iFrame as a buffer, it fills it up with your content
// and prompts the user to save it out.
function save_content_to_file(content, filename){
var dlg = false;
with(document){
ir=createElement('iframe');
ir.id='ifr';
ir.location='about.blank';
ir.style.display='none';
body.appendChild(ir);
with(getElementById('ifr').contentWindow.document){
open("text/plain", "replace");
charset = "utf-8";
write(content);
close();
document.charset = "utf-8";
dlg = execCommand('SaveAs', false, filename);
}
body.removeChild(ir);
}
return dlg;
}
Invoke the function like this:
msg = "I am the president of tautology club.";
save_content_to_file(msg, "C:\\test");
array_search
is the way to do it.
array_search ( mixed $needle , array $haystack [, bool $strict = FALSE ] ) : mixed
From the docs:
$array = array(0 => 'blue', 1 => 'red', 2 => 'green', 3 => 'red');
$key = array_search('green', $array); // $key = 2;
$key = array_search('red', $array); // $key = 1;
You could loop over the array manually and find the index but why do it when there's a function for that. This function always returns a key and it will work well with associative and normal arrays.
You can set the draggable
attribute to false
in either the markup or JavaScript code.
// As a jQuery method: $('#myImage').attr('draggable', false);_x000D_
document.getElementById('myImage').setAttribute('draggable', false);
_x000D_
<img id="myImage" src="http://placehold.it/150x150">
_x000D_
Note that if the problem is being caused by appearing scrollbars, putting
body {
overflow: hidden;
}
in your CSS might be an easy fix (if you don't need the page to scroll).
here is another solution I started using after being fed up with the copy and paste issue:
vmrun start D:\VM\MySuperVM1\vm1.vmx nogui vmrun start D:\VM\MySuperVM2\vm2.vmx nogui
save the file to startmyvms.cmd
create another batch file and add your vms
vmrun stop D:\VM\MySuperVM1\vm1.vmx nogui vmrun stop D:\VM\MySuperVM2\vm2.vmx nogui
save the file to stopmyvms.cmd
Open Mremote go to tools => External tools Add external tool => filename will be the startmyvms.cmd file Add external tool => filename will be the stopmyvms.cmd file So to start working with your vms:
Create you connections to your VMs in mremote
Now to work with your vm 1. You open mremote 2. You go to tools => external tools 3. You click the startmyvms tool when you're done 1. You go to tools => external tools 2. You click the stopmyvms external tool
you could add the vmrun start on the connection setting => external tool before connection and add the vmrun stop in the connection settings => external tool after
Voilà !
I was trying to install fancyimpute package for imputation but there was not luck. But when i tried below commands, it got installed: Commands:
conda update conda
conda update anaconda
pip install fancyimpute
(here i was trying to give command conda install fancyimpute which did't work)
Use sprintf.
int sprintf ( char * str, const char * format, ... );
Write formatted data to string Composes a string with the same text that would be printed if format was used on printf, but instead of being printed, the content is stored as a C string in the buffer pointed by str.
The size of the buffer should be large enough to contain the entire resulting string (see snprintf for a safer version).
A terminating null character is automatically appended after the content.
After the format parameter, the function expects at least as many additional arguments as needed for format.
str
Pointer to a buffer where the resulting C-string is stored. The buffer should be large enough to contain the resulting string.
format
C string that contains a format string that follows the same specifications as format in printf (see printf for details).
... (additional arguments)
Depending on the format string, the function may expect a sequence of additional arguments, each containing a value to be used to replace a format specifier in the format string (or a pointer to a storage location, for n). There should be at least as many of these arguments as the number of values specified in the format specifiers. Additional arguments are ignored by the function.
// Allocates storage
char *hello_world = (char*)malloc(13 * sizeof(char));
// Prints "Hello world!" on hello_world
sprintf(hello_world, "%s %s!", "Hello", "world");
This doesn't have the regex overhead
double myNum = 0;
String testVar = "Not A Number";
if (Double.TryParse(testVar, out myNum)) {
// it is a number
} else {
// it is not a number
}
Incidentally, all of the standard data types, with the glaring exception of GUIDs, support TryParse.
update
secretwep brought up that the value "2345," will pass the above test as a number. However, if you need to ensure that all of the characters within the string are digits, then another approach should be taken.
example 1:
public Boolean IsNumber(String s) {
Boolean value = true;
foreach(Char c in s.ToCharArray()) {
value = value && Char.IsDigit(c);
}
return value;
}
or if you want to be a little more fancy
public Boolean IsNumber(String value) {
return value.All(Char.IsDigit);
}
update 2 ( from @stackonfire to deal with null or empty strings)
public Boolean IsNumber(String s) {
Boolean value = true;
if (s == String.Empty || s == null) {
value=false;
} else {
foreach(Char c in s.ToCharArray()) {
value = value && Char.IsDigit(c);
}
} return value;
}
Here is my solution. Worked with script, which was ran by third party program with no WScript declared and no import allowed.
Function MySleep(milliseconds)
set WScriptShell = CreateObject("WScript.Shell")
WScriptShell.Run "Sleep -m " & milliseconds, 0, true
end Function
Update
Looks like Microsoft removed Sleep.exe from win 8, so this doesn't work in win 8 unless you put Sleep.exe in folder defined in %path%.
If you can re-create or parse your input data, you can specify an escape character for the CREATE TABLE:
ROW FORMAT DELIMITED FIELDS TERMINATED BY "," ESCAPED BY '\\';
Will accept this line as 4 fields
1,some text\, with comma in it,123,more text
PIL pixels are tuples, and tuples are immutable. You need to construct a new tuple. So, instead of the for loop, do:
pixels = [(pixel[0] + 20, pixel[1], pixel[2]) for pixel in pixels]
image.putdata(pixels)
Also, if the pixel is already too red, adding 20 will overflow the value. You probably want something like min(pixel[0] + 20, 255)
or int(255 * (pixel[0] / 255.) ** 0.9)
instead of pixel[0] + 20
.
And, to be able to handle images in lots of different formats, do image = image.convert("RGB")
after opening the image. The convert method will ensure that the pixels are always (r, g, b) tuples.
3 things you have to do, if you are doing it locally:
in php.ini
or php.cfg
of your php installation
post_max_size=500M
upload_max_filesize=500M
memory_limit=900M
or set other values. Restart Apache.
OR
Use php big dump tool its best ever i have seen. its free and opensource
Go to Gradle
file (module app), add below code block
android {
...
lintOptions {
disable 'ContentDescription'
}
...
}
No more warning! happy coding
Maybe You should try scrollIntoView.
document.getElementById('id').scrollIntoView();
This will scroll to your Element.
Use head
:
dnow <- data.frame(x=rnorm(100), y=runif(100))
head(dnow,4) ## default is 6
Note if you are using typings
do the following:
rm -r typings
typings install
If your doing the angular 2 tutorial use this:
rm -r typings
npm run postinstall
npm start
if the postinstall
command dosen't work, try installing typings globally like so:
npm install -g typings
you can also try the following as opposed to postinstall:
typings install
and you should have this issue fixed!
Your guess is right: the code is trying to evaluate x**3+2*x-4
immediately. Unfortunately you can't really prevent it from doing so. The good news is that in Python, functions are first-class objects, by which I mean that you can treat them like any other variable. So to fix your function, we could do:
import numpy as np
import matplotlib.pyplot as plt
def graph(formula, x_range):
x = np.array(x_range)
y = formula(x) # <- note now we're calling the function 'formula' with x
plt.plot(x, y)
plt.show()
def my_formula(x):
return x**3+2*x-4
graph(my_formula, range(-10, 11))
If you wanted to do it all in one line, you could use what's called a lambda
function, which is just a short function without a name where you don't use def
or return
:
graph(lambda x: x**3+2*x-4, range(-10, 11))
And instead of range
, you can look at np.arange
(which allows for non-integer increments), and np.linspace
, which allows you to specify the start, stop, and the number of points to use.
The correct way of building client/server Microsoft Access applications where the data is stored in a RDBMS is to use the Linked Table method. This ensures Data Isolation and Concurrency is maintained between the Microsoft Access client application and the RDBMS data with no additional and unnecessary programming logic and code which makes maintenance more difficult, and adds to development time.

1) git rebase -i HEAD~4
To elaborate: It works on the current branch; the HEAD~4 means squashing the latest four commits; interactive mode (-i)
2) At this point, the editor opened, with the list of commits, to change the second and following commits, replacing pick with squash then save it.
output: Successfully rebased and updated refs/heads/branch-name.
3) git push origin refs/heads/branch-name --force
output:

you need to take 2 (hex) chars at the same time... then calculate the int value and after that make the char conversion like...
char d = (char)intValue;
do this for every 2chars in the hex string
this works if the string chars are only 0-9A-F:
#include <stdio.h>
#include <string.h>
int hex_to_int(char c){
int first = c / 16 - 3;
int second = c % 16;
int result = first*10 + second;
if(result > 9) result--;
return result;
}
int hex_to_ascii(char c, char d){
int high = hex_to_int(c) * 16;
int low = hex_to_int(d);
return high+low;
}
int main(){
const char* st = "48656C6C6F3B";
int length = strlen(st);
int i;
char buf = 0;
for(i = 0; i < length; i++){
if(i % 2 != 0){
printf("%c", hex_to_ascii(buf, st[i]));
}else{
buf = st[i];
}
}
}
The voted up answer is missing a step.
Per aws s3 help:
Currently, there is no support for the use of UNIX style wildcards in a command's path arguments. However, most commands have
--exclude "<value>"
and--include "<value>"
parameters that can achieve the desired result......... When there are multiple filters, the rule is the filters that appear later in the command take precedence over filters that appear earlier in the command. For example, if the filter parameters passed to the command were--exclude "*"
--include "*.txt"
All files will be excluded from the command except for files ending with .txt
aws s3 rm --recursive s3://bucket/ --exclude="*" --include="/folder_path/*"
When I saw the same error, I tried to resolve it like:
__block CGFloat docHeight = 0.0;
[self evaluateJavaScript:@"document.height" completionHandler:^(id height, NSError *error) {
//height
NSLog(@"=========>document.height:@%@",height);
docHeight = [height floatValue];
}];
and its working fine
Just add "__block" before Variable.
With respect to the answer "getconf LONG_BIT".
I wrote a simple function to do it in 'C':
/*
* check_os_64bit
*
* Returns integer:
* 1 = it is a 64-bit OS
* 0 = it is NOT a 64-bit OS (probably 32-bit)
* < 0 = failure
* -1 = popen failed
* -2 = fgets failed
*
* **WARNING**
* Be CAREFUL! Just testing for a boolean return may not cut it
* with this (trivial) implementation! (Think of when it fails,
* returning -ve; this could be seen as non-zero & therefore true!)
* Suggestions?
*/
static int check_os_64bit(void)
{
FILE *fp=NULL;
char cb64[3];
fp = popen ("getconf LONG_BIT", "r");
if (!fp)
return -1;
if (!fgets(cb64, 3, fp))
return -2;
if (!strncmp (cb64, "64", 3)) {
return 1;
}
else {
return 0;
}
}
Good idea, the 'getconf'!
jQuery Validation Unobtrusive Native is a collection of ASP.Net MVC HTML helper extensions. These make use of jQuery Validation's native support for validation driven by HTML 5 data attributes. Microsoft shipped jquery.validate.unobtrusive.js back with MVC 3. It provided a way to apply data model validations to the client side using a combination of jQuery Validation and HTML 5 data attributes (that's the "unobtrusive" part).
First of all getting users mobile number is against the Ethical policy, earlier it was possible but now as per my research there no solid solution available for this, By using some code it is possible to get mobile number but no guarantee may be it will work only in few device. After lot of research i found only three solution but they are not working in all device.
There is the following reason why we are not getting.
1.Android device and new Sim Card not storing mobile number if mobile number is not available in device and in sim then how it is possible to get number, if any old sim card having mobile number then using Telephony manager we can get the number other wise it will return the “null” or “” or “??????”
<uses-permission android:name="android.permission.READ_PHONE_STATE"/>
TelephonyManager tel= (TelephonyManager)this.getSystemService(Context.
TELEPHONY_SERVICE);
String PhoneNumber = tel.getLine1Number();
Note:- I have tested this solution in following device Moto x, Samsung Tab 4, Samsung S4, Nexus 5 and Redmi 2 prime but it doesn’t work every time it return empty string so conclusion is it's useless
Note:- This is also not the guaranteed and efficient solution, I have tested this solution in many device but it worked only in Redmi 2 prime which is dual sim device it gives me two mobile number first one is correct but the second one is not belong to my second sim it belong to my some old sim card which i am not using.
String main_data[] = {"data1", "is_primary", "data3", "data2", "data1",
"is_primary", "photo_uri", "mimetype"};
Object object = getContentResolver().
query(Uri.withAppendedPath(android.provider.ContactsContract.Profile.CONTENT_URI, "data"),
main_data, "mimetype=?",
new String[]{"vnd.android.cursor.item/phone_v2"},
"is_primary DESC");
String s1="";
if (object != null) {
do {
if (!((Cursor) (object)).moveToNext())
break;
// This is the phoneNumber
s1 =s1+"---"+ ((Cursor) (object)).getString(4);
} while (true);
((Cursor) (object)).close();
}
Conclusion:- Android doesn’t have any guaranteed solution to get user's mobile number programmatically.
Suggestion:- 1. If you want to verify user’s mobile number then ask to user to provide his number, using otp you can can verify that.
- If you want to identify the user’s device, for this you can easily get device IMEI number.
It's better, if you use two div containers in HTML .
As Shown Below:
HTML:
<div id="container1">
<div id="container2">
// Content here
</div>
</div>
CSS:
#container1{
height: 100%;
width: 100%;
overflow: hidden;
}
#container2{
height: 100%;
width: 100%;
overflow: auto;
padding-right: 20px;
}
When you use the parameter "--save" your dependency will go inside the #1 below in package.json. When you use the parameter "--save-dev" your dependency will go inside the #2 below in package.json.
#1. "dependencies": these packages are required by your application in production.
#2. "devDependencies": these packages are only needed for development and testing
Your makefile should ideally be named makefile
, not make
. Note that you can call your makefile anything you like, but as you found, you then need the -f
option with make
to specify the name of the makefile. Using the default name of makefile
just makes life easier.
Sort the unsorted hashmap in ascending order.
// Sorting the list based on values
Collections.sort(list, new Comparator<Entry<String, Integer>>() {
public int compare(Entry<String, Integer> o1, Entry<String, Integer> o2)
{
return o2.getValue().compareTo(o1.getValue());
}
});
// Maintaining insertion order with the help of LinkedList
Map<String, Integer> sortedMap = new LinkedHashMap<String, Integer>();
for (Entry<String, Integer> entry : list) {
sortedMap.put(entry.getKey(), entry.getValue());
}
It does work in Firefox (including 2.0.0.20
). See http://jsbin.com/akili (add /edit
to the url to edit):
<p id="one">One</p>
<a href="#" onclick="document.getElementById('one').id = 'two'; return false">Link2</a>
The first click changes the id
to "two"
, the second click errors because the element with id="one"
now can't be found!
Perhaps you have another element already with id="two"
(FYI you can't have more than one element with the same id
).
Try this:
CASE WHEN table3.col3 IS NULL THEN table2.col3 ELSE table3.col3 END as col4
The as col4
should go at the end of the CASE the statement. Also note that you're missing the END
too.
Another probably more simple option would be:
IIf([table3.col3] Is Null,[table2.col3],[table3.col3])
Just to clarify, MS Access does not support COALESCE. If it would that would be the best way to go.
Edit after radical question change:
To turn the query into SQL Server then you can use COALESCE (so it was technically answered before too):
SELECT dbo.AdminID.CountryID, dbo.AdminID.CountryName, dbo.AdminID.RegionID,
dbo.AdminID.[Region name], dbo.AdminID.DistrictID, dbo.AdminID.DistrictName,
dbo.AdminID.ADMIN3_ID, dbo.AdminID.ADMIN3,
COALESCE(dbo.EU_Admin3.EUID, dbo.EU_Admin2.EUID)
FROM dbo.AdminID
BTW, your CASE statement was missing a ,
before the field. That's why it didn't work.
So with the code you have provided.
var bytes = Convert.FromBase64String(resizeImage.Content);
using (var imageFile = new FileStream(filePath, FileMode.Create))
{
imageFile.Write(bytes ,0, bytes.Length);
imageFile.Flush();
}
The syntax of Array.splice
is:
yourArray.splice(index, howmany, element1, /*.....,*/ elementX);
Where:
This means that splice()
can be used to remove elements, add elements, or replace elements in an array, depending on the arguments you pass.
Note that it returns an array of the removed elements.
Something nice and generic would be:
Array.prototype.move = function (from, to) {
this.splice(to, 0, this.splice(from, 1)[0]);
};
Then just use:
var ar = [1,2,3,4,5];
ar.move(0,3);
alert(ar) // 2,3,4,1,5

To start the process with parameters, you can use following code:
string filename = Path.Combine(cPath,"HHTCtrlp.exe");
var proc = System.Diagnostics.Process.Start(filename, cParams);
To kill/exit the program again, you can use following code:
proc.CloseMainWindow();
proc.Close();
the line below shows you haven't set an DataAttribute like required on AgreementNumber
<input id="AgreementNumber" name="AgreementNumber" size="30" type="text" value="387893" />
you need
[Required]
public String AgreementNumber{get;set;}
It looks like the only way to achieve this is by setting
browser.display.focus_ring_width = 0
in about:config on a per browser basis.
If response is in json and not a string then
alert(response.id);
or
alert(response['id']);
otherwise
var response = JSON.parse('{"id":"2231f87c-a62c-4c2c-8f5d-b76d11942301"}');
response.id ; //# => 2231f87c-a62c-4c2c-8f5d-b76d11942301
I am using entity framework with LINQ. Following code was helpful for me;
1- For multiple records
using (var dbContext = new Chat_ServerEntities())
{
var allRec= dbContext.myEntities;
dbContext.myEntities.RemoveRange(allRec);
dbContext.SaveChanges();
}
2- For Single record
using (var dbContext = new Chat_ServerEntities())
{
var singleRec = dbContext.ChatUserConnections.FirstOrDefault( x => x.ID ==1);// object your want to delete
dbContext.ChatUserConnections.Remove(singleRec);
dbContext.SaveChanges();
}
<script>
var myVar = <?php echo json_encode($myVarValue); ?>;
</script>
or
<script>
var myVar = <?= json_encode($myVarValue) ?>;
</script>
try
<div style='overflow:auto; width:400px;height:400px;'>here is some text</div>
For me, align="center"
was enough to center FOO
vertically:
<v-row align="center">
<v-col>FOO</v-col>
</row>
Besides using one of the default formats you can specify any size you want in the unit you specify.
For example:
// Document of 210mm wide and 297mm high
new jsPDF('p', 'mm', [297, 210]);
// Document of 297mm wide and 210mm high
new jsPDF('l', 'mm', [297, 210]);
// Document of 5 inch width and 3 inch high
new jsPDF('l', 'in', [3, 5]);
The 3rd parameter of the constructor can take an array of the dimensions. However they do not correspond to width and height, instead they are long side and short side (or flipped around).
Your 1st parameter (landscape
or portrait
) determines what becomes the width and the height.
In the sourcecode on GitHub you can see the supported units (relative proportions to pt
), and you can also see the default page formats (with their sizes in pt
).
Simply pass the sorted items from the dictionary to the plot()
function. concentration.items()
returns a list of tuples where each tuple contains a key from the dictionary and its corresponding value.
You can take advantage of list unpacking (with *
) to pass the sorted data directly to zip, and then again to pass it into plot()
:
import matplotlib.pyplot as plt
concentration = {
0: 0.19849878712984576,
5000: 0.093917341754771386,
10000: 0.075060643507712022,
20000: 0.06673074282575861,
30000: 0.057119318961966224,
50000: 0.046134834546203485,
100000: 0.032495766396631424,
200000: 0.018536317451599615,
500000: 0.0059499290585381479}
plt.plot(*zip(*sorted(concentration.items())))
plt.show()
sorted()
sorts tuples in the order of the tuple's items so you don't need to specify a key
function because the tuples returned by dict.item()
already begin with the key value.
I've created Xcode 4 templates to simplify the steps provided by Tyler.
The result is Python Project Template for Xcode 4.
Now what you need to do is download the templates, move it to /Developer/Library/Xcode/Templates/Project Templates/Mac/Others/
and then new a Python project with Xcode 4.
It still needs manual Scheme setup (you can refer to steps 12–20 provided by Tyler.)
Just run the command:
php artisan migrate:refresh --seed
Here's a simple css only solution, that creates a consistent target area, and lets you style your faux elements however you like.
The basic idea is this:
Here's the jsfiddle: http://jsfiddle.net/gwwar/nFLKU/
<form>
<input id="faux" type="text" placeholder="Upload a file from your computer" />
<a href="#" id="browse">Browse </a>
<div id="wrapper">
<input id="input" size="100" type="file" />

You could just create an array of the correct size up-front and fill it:
frames = np.empty((480, 640, 3, 100))
for k in xrange(nframes):
frames[:,:,:,k] = cv2.imread('frame_{}.jpg'.format(k))
if the frames were individual jpg file that were named in some particular way (in the example, frame_0.jpg, frame_1.jpg, etc).
Just a note, you might consider using a (nframes, 480,640,3)
shaped array, instead.
Yahoo! This is really possible. I found it.
For Bottom Border:
div {box-shadow: 0px -3px 0px red inset; }
For Top Border:
div {box-shadow: 0px 3px 0px red inset; }
You can use Schedule
inline fun Timer.schedule(
delay: Long,
crossinline action: TimerTask.() -> Unit
): TimerTask (source)
example (thanks @Nguyen Minh Binh - found it here: http://jamie.mccrindle.org/2013/02/exploring-kotlin-standard-library-part-3.html)
import java.util.Timer
import kotlin.concurrent.schedule
Timer("SettingUp", false).schedule(500) {
doSomething()
}
Indeed SET TEST_VARIABLE=value works for current process only, so SETX
is required. A quick example for permanently storing an environment variable at user level.
SETX TEST_VARIABLE etc
. Not applied yet (echo %TEST_VARIABLE%
shows %TEST_VARIABLE%
,echo %TEST_VARIABLE%
shows etc
.etc
.If you mean what ports are listening, you can open a command prompt and write:
netstat
You can write:
netstat /?
for an explanation of all options.
.focus()
and then .blur()
something else arbitrary on your page. Since only one element can have the focus, it is transferred to that element and then removed.
You can use -O-
(uppercase o) to redirect content to the stdout (standard output) or to a file (even special files like /dev/null
/dev/stderr
/dev/stdout
)
wget -O- http://yourdomain.com
Or:
wget -O- http://yourdomain.com > /dev/null
Or: (same result as last command)
wget -O/dev/null http://yourdomain.com
I was getting the same error while connecting my "hr" user of ORCLPDB which is a pluggable database.
First, get hostname and port number by typing a command lsnrctl status
on windows command prompt. In my case, it was 127.0.0.1 with port number as 1521
Second, enter the below command with your hostname and port number:
sqlplus username/password@HostName:Port Number/PluggableDatabaseName.
For example:
sqlplus hr/[email protected]:1521/ORCLPDB.
You can use Include Directives
<%
if(request.getParameter("p")!=null)
{
String p = request.getParameter("p");
%>
<%@include file="<%="includes/" + p +".jsp"%>"%>
<%
}
%>
or JSP Include Action
<%
if(request.getParameter("p")!=null)
{
String p = request.getParameter("p");
%>
<jsp:include page="<%="includes/"+p+".jsp"%>"/>
<%
}
%>
the different is include directive includes a file during the translation phase. while JSP Include Action includes a file at the time the page is requested
I recommend Spring MVC Framework as your controller to manipulate things. use url pattern instead of parameter.
example:
www.yourwebsite.com/products
instead of
www.yourwebsite.com/?p=products
Watch this video Spring MVC Framework
Your code works when run in an script because Python encodes the output to whatever encoding your terminal application is using. If you are piping you must encode it yourself.
A rule of thumb is: Always use Unicode internally. Decode what you receive, and encode what you send.
# -*- coding: utf-8 -*-
print u"åäö".encode('utf-8')
Another didactic example is a Python program to convert between ISO-8859-1 and UTF-8, making everything uppercase in between.
import sys
for line in sys.stdin:
# Decode what you receive:
line = line.decode('iso8859-1')
# Work with Unicode internally:
line = line.upper()
# Encode what you send:
line = line.encode('utf-8')
sys.stdout.write(line)
Setting the system default encoding is a bad idea, because some modules and libraries you use can rely on the fact it is ASCII. Don't do it.
public class Test1 {
/**
* @param args
*/
public static void main(String[] args) {
// TODO Auto-generated method stub
System.out.println("helow");
String where="where task in ";
where+="(";
// where+="'task1'";
int num[]={1,2,3,4};
for (int i=0;i<num.length+1;i++) {
if(i==1){
where +="'"+i+"'";
}
if(i>1 && i<num.length)
where+=", '"+i+"'";
if(i==num.length){
System.out.println("This is last number"+i);
where+=", '"+i+"')";
}
}
System.out.println(where);
}
}
You can create your <script>
element with an "onload" handler, and that will be called when the script has been loaded and evaluated by the browser.
var script = document.createElement('script');
script.onload = function() {
alert("Script loaded and ready");
};
script.src = "http://whatever.com/the/script.js";
document.getElementsByTagName('head')[0].appendChild(script);
You can't do it synchronously.
edit — it's been pointed out that, true to form, IE doesn't fire a "load" event on <script>
tags being loaded/evaluated. Thus I suppose the next thing to do would be to fetch the script with an XMLHttpRequest and then eval()
it yourself. (Or, I suppose, stuff the text into a <script>
tag you add; the execution environment of eval()
is affected by the local scope, so it won't necessarily do what you want it to do.)
edit — As of early 2013, I'd strongly advise looking into a more robust script loading tool like Requirejs. There are a lot of special cases to worry about. For really simple situations, there's yepnope, which is now built into Modernizr.
String
objects in Java use the UTF-16 encoding that can't be modified.
The only thing that can have a different encoding is a byte[]
. So if you need UTF-8 data, then you need a byte[]
. If you have a String
that contains unexpected data, then the problem is at some earlier place that incorrectly converted some binary data to a String
(i.e. it was using the wrong encoding).
Here is some code that show how it works.
class Test
{
public static void main(String args[])
{
System.out.println(Test.test());
}
public static String test()
{
try {
System.out.println("try");
throw new Exception();
} catch(Exception e) {
System.out.println("catch");
return "return";
} finally {
System.out.println("finally");
return "return in finally";
}
}
}
The results is:
try
catch
finally
return in finally
Try this using list comprehension:
import pandas as pd
df = pd.DataFrame(
[p, p.team, p.passing_att, p.passer_rating()] for p in game.players.passing()
)
It’s easy; just do the following:
rvm implode
or
rm -rf ~/.rvm
And don’t forget to remove the script calls in the following files:
~/.bashrc
~/.bash_profile
~/.profile
And maybe others depending on whatever shell you’re using.
I'm using it from this site, also it looks good. Have a look at it Inner shadow
I ran into this issue on a corporate development VM which wasn't running OpenVPN. Checking out etc/docker/daemon.json
, I found
...
"default-address-pools": [
{
"base": "192.168.11.0/24",
"size": 24
}
],
...
Strangely, removing the default-address-pools
field and then restarting docker with sudo systemctl restart docker
fixed the issue for me. I'm assuming this let docker choose a more suitable default, but I don't know what the problem was with the chosen default.
You need to use : "$@"
(WITH the quotes) or "${@}"
(same, but also telling the shell where the variable name starts and ends).
(and do NOT use : $@
, or "$*"
, or $*
).
ex:
#testscript1:
echo "TestScript1 Arguments:"
for an_arg in "$@" ; do
echo "${an_arg}"
done
echo "nb of args: $#"
./testscript2 "$@" #invokes testscript2 with the same arguments we received
I'm not sure I understood your other requirement ( you want to invoke './testscript2' in single quotes?) so here are 2 wild guesses (changing the last line above) :
'./testscript2' "$@" #only makes sense if "/path/to/testscript2" containes spaces?
./testscript2 '"some thing" "another"' "$var" "$var2" #3 args to testscript2
Please give me the exact thing you are trying to do
edit: after his comment saying he attempts tesscript1 "$1" "$2" "$3" "$4" "$5" "$6" to run : salt 'remote host' cmd.run './testscript2 $1 $2 $3 $4 $5 $6'
You have many levels of intermediate: testscript1 on host 1, needs to run "salt", and give it a string launching "testscrit2" with arguments in quotes...
You could maybe "simplify" by having:
#testscript1
#we receive args, we generate a custom script simulating 'testscript2 "$@"'
theargs="'$1'"
shift
for i in "$@" ; do
theargs="${theargs} '$i'"
done
salt 'remote host' cmd.run "./testscript2 ${theargs}"
if THAt doesn't work, then instead of running "testscript2 ${theargs}", replace THE LAST LINE above by
echo "./testscript2 ${theargs}" >/tmp/runtestscript2.$$ #generate custom script locally ($$ is current pid in bash/sh/...)
scp /tmp/runtestscript2.$$ user@remotehost:/tmp/runtestscript2.$$ #copy it to remotehost
salt 'remotehost' cmd.run "./runtestscript2.$$" #the args are inside the custom script!
ssh user@remotehost "rm /tmp/runtestscript2.$$" #delete the remote one
rm /tmp/runtestscript2.$$ #and the local one
Here is my cover fill solution (similar to background-size: cover, but it supports old IE browser)
<div class="imgContainer" style="height:100px; width:500px; overflow:hidden; background-color: black">
<img src="http://dev.isaacsonwebdevelopment.com/sites/development/files/views-slideshow-settings-jquery-cycle-custom-options-message.png" id="imgCat">
</div>
<script src="http://ajax.aspnetcdn.com/ajax/jQuery/jquery-1.11.3.min.js"></script>
<script>
$(window).load(function() {
var heightRate =$("#imgCat").height() / $("#imgCat").parent(".imgContainer").height();
var widthRate = $("#imgCat").width() / $("#imgCat").parent(".imgContainer").width();
if (window.console) {
console.log($("#imgCat").height());
console.log(heightRate);
console.log(widthRate);
console.log(heightRate > widthRate);
}
if (heightRate <= widthRate) {
$("#imgCat").height($("#imgCat").parent(".imgContainer").height());
} else {
$("#imgCat").width($("#imgCat").parent(".imgContainer").width());
}
});
</script>
An INT
will always be 4 bytes no matter what length is specified.
TINYINT
= 1 byte (8 bit)SMALLINT
= 2 bytes (16 bit)MEDIUMINT
= 3 bytes (24 bit)INT
= 4 bytes (32 bit)BIGINT
= 8 bytes (64 bit).The length just specifies how many characters to pad when selecting data with the mysql command line client. 12345 stored as int(3)
will still show as 12345, but if it was stored as int(10)
it would still display as 12345, but you would have the option to pad the first five digits. For example, if you added ZEROFILL
it would display as 0000012345.
... and the maximum value will be 2147483647 (Signed) or 4294967295 (Unsigned)
Example:
import React from 'react';
import PropTypes from 'prop-types';
class MenuItem extends React.Component {
render() {
return (
<li>
<a href={this.props.href}>{this.props.children}</a>
</li>
);
}
}
MenuItem.defaultProps = {
href: "/",
children: "Main page"
};
MenuItem.propTypes = {
href: PropTypes.string.isRequired,
children: PropTypes.string.isRequired
};
export default MenuItem;
Picture: Shows you error in console if the expected type is different
Well in my case I just opened services.msc using run and restarted 2 of the services related to mysql and it worked!
Moment js solution to this is
var d = new Date(new Date().setHours(0,0,0,0));
m.add(m.utcOffset(), 'm')
m.toDate().toISOString()
// output "2019-07-18T00:00:00.000Z"
Ask the user for the exact URL they're using in their browser. If they're entering https://your.site:80, they may receive the ssl_error_rx_record_too_long error.
The answer above is correct. Please be sure that you have a string data in base64 in the data variable without any prefix or stuff like that just raw data.
Here's what I did on the server side (asp.net mvc core):
string path = Path.Combine(folder, fileName);
Byte[] bytes = System.IO.File.ReadAllBytes(path);
string base64 = Convert.ToBase64String(bytes);
On the client side, I did the following code:
const xhr = new XMLHttpRequest();
xhr.open("GET", url);
xhr.setRequestHeader("Content-Type", "text/plain");
xhr.onload = () => {
var bin = atob(xhr.response);
var ab = s2ab(bin); // from example above
var blob = new Blob([ab], { type: 'application/vnd.openxmlformats-officedocument.spreadsheetml.sheet;' });
var link = document.createElement('a');
link.href = window.URL.createObjectURL(blob);
link.download = 'demo.xlsx';
document.body.appendChild(link);
link.click();
document.body.removeChild(link);
};
xhr.send();
And it works perfectly for me.
Oracle
stores numbers in the following way: 1 byte
for power, 1 byte
for the first significand digit (that is one before the separator), the rest for the other digits.
By digits
here Oracle
means centesimal digits
(i. e. base 100
)

This is default database :
$db['default'] = array(
'dsn' => '',
'hostname' => 'localhost',
'username' => 'root',
'password' => '',
'database' => 'mydatabase',
'dbdriver' => 'mysqli',
'dbprefix' => '',
'pconnect' => TRUE,
'db_debug' => (ENVIRONMENT !== 'production'),
'cache_on' => FALSE,
'cachedir' => '',
'char_set' => 'utf8',
'dbcollat' => 'utf8_general_ci',
'swap_pre' => '',
'encrypt' => FALSE,
'compress' => FALSE,
'stricton' => FALSE,
'failover' => array(),
'save_queries' => TRUE
);
Add another database at the bottom of database.php file
$db['second'] = array(
'dsn' => '',
'hostname' => 'localhost',
'username' => 'root',
'password' => '',
'database' => 'mysecond',
'dbdriver' => 'mysqli',
'dbprefix' => '',
'pconnect' => TRUE,
'db_debug' => (ENVIRONMENT !== 'production'),
'cache_on' => FALSE,

'swap_pre' => '',
'encrypt' => FALSE,
'compress' => FALSE,
'stricton' => FALSE,
'failover' => array(),
'save_queries' => TRUE
);
In autoload.php config file
$autoload['libraries'] = array('database', 'email', 'session');
The default database is worked fine by autoload the database library but second database load and connect by using constructor in model and controller...
<?php
class Seconddb_model extends CI_Model {
function __construct(){
parent::__construct();
//load our second db and put in $db2
$this->db2 = $this->load->database('second', TRUE);
}
public function getsecondUsers(){
$query = $this->db2->get('members');
return $query->result();
}
}
?>

^ - .NET 5.0 is not a newer version of .NET framework but .NET Core 3. Starting from .NET 5.0, there are no newer versions of .NET full framework.
^^ - There are no separate CLR (CoreCLR) versions for .NET Core. Whatever is the .NET Core version is the CoreCLR version. So not mentioning it.
Note: .NET development is pretty much independent of VS these days, there is no correlation between versions of each.

The code described offers many of the advantages of C# delegates. Methods, either static or dynamic, can be treated in a uniform manner. The complexity in calling methods through reflection is reduced and the code is reusable, in the sense of requiring no additional classes in the user code. Note we are calling an alternate convenience version of invoke, where a method with one parameter can be called without creating an object array.Java code below:
class Class1 {
public void show(String s) { System.out.println(s); }
}
class Class2 {
public void display(String s) { System.out.println(s); }
}
// allows static method as well
class Class3 {
public static void staticDisplay(String s) { System.out.println(s); }
}
public class TestDelegate {
public static final Class[] OUTPUT_ARGS = { String.class };
public final Delegator DO_SHOW = new Delegator(OUTPUT_ARGS,Void.TYPE);
public void main(String[] args) {
Delegate[] items = new Delegate[3];
items[0] = DO_SHOW .build(new Class1(),"show,);
items[1] = DO_SHOW.build (new Class2(),"display");
items[2] = DO_SHOW.build(Class3.class, "staticDisplay");
for(int i = 0; i < items.length; i++) {
items[i].invoke("Hello World");
}
}
}
Use find
with a wildcard:
find . -name 'mystring*'
I had the same problem and found out that you have to escape spaces in the extra:
adb shell am broadcast -a com.whereismywifeserver.intent.TEST --es sms_body "test\ from\ adb"
So instead of "test from adb" it should be "test\ from\ adb"
Your program will continue with the second if
statement in the case of y == x
, causing a ZeroDivisionError
. You need to make the statements mutually exclusive; the way to do that is to use elif
("else if") instead of if
:
import math
x = int(input("Enter a value for x: "))
y = int(input("Enter a value for y: "))
if y == x:
print(1)
elif y == 1: # see georg's comment
print(x)
elif y > x: # will be executed only if y != 1 and y != x
print(0)
else: # will be executed only if y != 1 and y != x and x <= y
a = math.factorial(x)
b = math.factorial(y)
c = math.factorial(x-y) # that appears to be useful to get the correct result
div = a // (b * c)
print(div)
Without the need to install the grep variant pcregrep, you can do multiline search with grep.
$ grep -Pzo "(?s)^(\s*)\N*main.*?{.*?^\1}" *.c
Explanation:
-P
activate perl-regexp for grep (a powerful extension of regular expressions)
-z
suppress newline at the end of line, substituting it for null character. That is, grep knows where end of line is, but sees the input as one big line.
-o
print only matching. Because we're using -z
, the whole file is like a single big line, so if there is a match, the entire file would be printed; this way it won't do that.
In regexp:
(?s)
activate PCRE_DOTALL
, which means that .
finds any character or newline
\N
find anything except newline, even with PCRE_DOTALL
activated
.*?
find .
in non-greedy mode, that is, stops as soon as possible.
^
find start of line
\1
backreference to the first group (\s*
). This is a try to find the same indentation of method.
As you can imagine, this search prints the main method in a C (*.c
) source file.
In my case,I was getting error while refreshing gradle ('View'->Tool Windows->Gradle) tab and hit "refresh" and getting this error no such property gradleversion for class jetgradleplugin.

You can install other builds but not Appstore build.
From Xcode 8.2,drag and drop the build to simulator for the installation.
A simpler option: just uncomment the following part of the configuration (which is originally commented out) in the /etc/vim/vimrc file:
if has("autocmd")
filetype plugin indent on
endif
If you specify the option 'openany' in the \documentclass declaration each chapter in the book (I'm guessing you're using the book class as chapters open on the next page in reports and articles don't have chapters) will open on a new page, not necessarily the next odd-numbered page.
Of course, that's not quite what you want. I think you want to set openany for chapters in the appendix. 'fraid I don't know how to do that, I suspect that you need to roll up your sleeves and wrestle with TeX itself
One option would be to use the onResume of your first activity.
@Override
public void onResume()
{ // After a pause OR at startup
super.onResume();
//Refresh your stuff here
}
Or you can start Activity for Result:
Intent i = new Intent(this, SecondActivity.class);
startActivityForResult(i, 1);
In secondActivity if you want to send back data:
Intent returnIntent = new Intent();
returnIntent.putExtra("result",result);
setResult(RESULT_OK,returnIntent);
finish();
if you don't want to return data:
Intent returnIntent = new Intent();
setResult(RESULT_CANCELED, returnIntent);
finish();
Now in your FirstActivity class write following code for onActivityResult()
method
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode == 1) {
if(resultCode == RESULT_OK){
//Update List
}
if (resultCode == RESULT_CANCELED) {
//Do nothing?
}
}
}//onActivityResult
So I have faced the same problem when trying to start apache service and I would like to share my solutions with you. Here is some notes about services or programs that may use port 80:
These options work great with me and I can start apache service without errors.
The other option is to change apache listen port from httpd.conf and set another port number.
Hope this solution helps anyone who face the same problem again.
I found this article enlightening : Javascript Madness: Query String Parsing
I found it when I was trying to undersand why decodeURIComponent was not decoding '+' correctly. Here is an extract:
String: "A + B"
Expected Query String Encoding: "A+%2B+B"
escape("A + B") = "A%20+%20B" Wrong!
encodeURI("A + B") = "A%20+%20B" Wrong!
encodeURIComponent("A + B") = "A%20%2B%20B" Acceptable, but strange
Encoded String: "A+%2B+B"
Expected Decoding: "A + B"
unescape("A+%2B+B") = "A+++B" Wrong!
decodeURI("A+%2B+B") = "A+++B" Wrong!
decodeURIComponent("A+%2B+B") = "A+++B" Wrong!
(Please read warning below)
Really simple way to do this in Windows (works with git bash, possibly others) is to create an environmental variable called HOME that points to your desired home directory.
NOTE: This may change the way other things work. For example, for me it changes where my .ssh config files live. In my case, I wanted my home to be U:\, because that's my main place that I put project work and application settings (i.e. it really is my "home" directory).
EDIT June 23, 2017: This answer continues to get occasional upvotes, and I want to warn people that although this may "work", I agree with @AnthonyRaymond that it's not recommended. This is more of a temporary fix or a fix if you don't care if other things break. Changing your home won't cause active damage (like deleting your hard drive) but it's likely to cause insidious annoyances later. When you do start to have annoying problems down the road, you probably won't remember this change... so you're likely to be scratching your head later on!
private function sendHttpRequest($host, $path, $query, $port=80){
header("POST $path HTTP/1.1\r\n" );

header("Content-length: " . strlen($query) . "\r\n" );
header("Connection: close\r\n\r\n" );
header($query);
}
This will get you right away

Sometimes if you are making a target via make files double check that all c files are named correctly with correct file structure.
I assume you are executing all of the above code each time you write something to the file. Each time the stream for the file is opened, its seek pointer is positioned at the beginning so all writes end up overwriting what was there before.
You can solve the problem in two ways: either with the convenient
file2 = new StreamWriter("c:/file.txt", true);
or by explicitly repositioning the stream pointer yourself:
file2 = new StreamWriter("c:/file.txt");
file2.BaseStream.Seek(0, SeekOrigin.End);
I came here because I had the same problem.
What was the problem for me was that the procedure was defined in the package body, but not in the package header.
I was executing my function with a lose BEGIN END statement.
Rule #1 of security for programmers: Don't roll your own
Unless you are yourself a security expert and/or cryptographer, always use a well-designed, well-tested, and mature security platform, framework, or library to do the work for you. These things have spent years being thought out, patched, updated, and examined by experts and hackers alike. You want to gain those advantages, not dismiss them by trying to reinvent the wheel.
Now, that's not to say you don't need to learn anything about security. You certainly need to know enough to understand what you're doing and make sure you're using the tools correctly. However, if you ever find yourself about to start writing your own cryptography algorithm, authentication system, input sanitizer, etc, stop, take a step back, and remember rule #1.

I think the answer for your question is here
To have Chrome send Access-Control-Allow-Origin in the header, just alias your localhost in your /etc/hosts file to some other domain, like:
127.0.0.1 localhost yourdomain.com
$('div').css({
position: 'relative',
top: '-15px'
});
Hold on...
From my experience, you SHOULD make sure that the DocumCompleted
belongs to YOUR URL and not to a frame sub-page, script, image, CSS, etc. And that is regardless of the IsBusy
or the ReadyState
is finished or not, which both are often inaccurate when page is slightly complex.
Well, that is my own personal experience, on a working program of VB.2013 and IE11. Let me also mention that you should take into account also the compatibility mode IE7 which is ON by default at the webBrowser1
.
' Page, sub-frame or resource was totally loaded.
Private Sub webBrowser1_DocumentCompleted(sender As Object, _
e As WebBrowserDocumentCompletedEventArgs) _
Handles webBrowser1.DocumentCompleted
' Check if finally the full page was loaded (inc. sub-frames, javascripts, etc)
If e.Url.ToString = webBrowser1.Url.ToString Then
' Only now you are sure!
fullyLoaded = True
End If
End Sub

To determine the brightness of a color with R, I convert the RGB system color in HSV system color.
In my script, I use the HEX system code before for other reason, but you can start also with RGB system code with rgb2hsv {grDevices}
. The documentation is here.
Here is this part of my code:
sample <- c("#010101", "#303030", "#A6A4A4", "#020202", "#010100")
hsvc <-rgb2hsv(col2rgb(sample)) # convert HEX to HSV
value <- as.data.frame(hsvc) # create data.frame
value <- value[3,] # extract the information of brightness
order(value) # ordrer the color by brightness
Please try the following:
import re
name = ["A1B1", "djdd", "B2C4", "C2H2", "jdoi","1A4V"]
# Match names.
for element in name:
m = re.match("(^[A-Z]\d[A-Z]\d)", element)
if m:
print(m.groups())
Capture the KeyboardInterrupt

exit()
For me it was enough to reinstall whitelist plugin:
cordova plugin remove cordova-plugin-whitelist
and then
cordova plugin add cordova-plugin-whitelist
It looks like updating from previous versions of Cordova was not succesful.
I have implemented CardView for react-native with elevation, that support android(All version) and iOS. Let me know is it help you or not. https://github.com/Kishanjvaghela/react-native-cardview

System.out.println("prior cond" + value);
if (value.equals("two")) {
System.out.println(value);
yes.set(false);
}

All this peace of code put into *.bat file and run all at once:

create file import.bat and put this lines in it:
SQLPLUS SYSTEM/systempassword@ORA_alias @"crate_drop_user.SQL"
IMP SYSTEM/systempassword@ORA_alias FILE=user.DMP FROMUSER=user TOUSER=user GRANTS=Y log =user.log
Be carefull if you will import from one user to another. For example if you have user named user1 and you will import to user2 you may lost all grants , so you have to recreate it.
Good luck, Ivan
If you're having problems with phpize not found on CentOS7.x after you have installed the relevant devel tools for your version/s of PHP, this path finally worked for me:
For PHP 7.2.x
/opt/cpanel/ea-php72/root/usr/bin/phpize
For PHP 7.3.x
/opt/cpanel/ea-php73/root/usr/bin/phpize
For PHP 7.4.x
/opt/cpanel/ea-php74/root/usr/bin/phpize
Run this in your folder containing the downloaded PHP extension, for example in line 3 below:
git clone --recursive --depth=1 https://github.com/kjdev/php-ext-brotli.git
cd /php-ext-brotli
/opt/cpanel/ea-php73/root/usr/bin/phpize
./configure --with-php-config=/opt/cpanel/ea-php73/root/usr/bin/php-config
make
make test
I've used another practice for this problem with multer dependancie.
Example:
multer = require('multer');
var uploading = multer({
limits: {fileSize: 1000000, files:1},
});
exports.uploadpictureone = function(req, res) {
cloudinary.uploader.upload(req.body.url, function(result) {
res.send(result);
});
};
module.exports = function(app) {
app.route('/api/upload', uploading).all(uploadPolicy.isAllowed)
.post(upload.uploadpictureone);
};
In addition to @Bikesh M Annur's answer, be sure to update your support libraries. Previously I was using 23.1.1 and nothing happened. Updating it to 23.3.0 did the trick.
I used to set this CSS to remove the reset :
ul {
list-style-type: disc;
list-style-position: inside;
}
ol {
list-style-type: decimal;
list-style-position: inside;
}
ul ul, ol ul {
list-style-type: circle;
list-style-position: inside;
margin-left: 15px;
}
ol ol, ul ol {
list-style-type: lower-latin;
list-style-position: inside;
margin-left: 15px;
}
EDIT : with a specific class of course...
Try Logic Friday 1
It includes tools from the Univerity of California (Espresso and misII) and makes them usable with a GUI. You can enter boolean equations and truth tables as desired. It also features a graphical gate diagram input and output.
The minimization can be carried out two-level or multi-level. The two-level form yields a minimized sum of products. The multi-level form creates a circuit composed out of logical gates. The types of gates can be restricted by the user.
Your expression simplifies to C
.
So , just make sure that you are on the right environment i.e 32 bit SWT LIBRARIES should match 32 bit JVM , vice versa.
I solved this problem by installing 64-bit jdk ,64-bit jre and finally by adding setting the jdk path in environment variables adn adding jre to the eclipse.
Git detects renames rather than persisting the operation with the commit, so whether you use git mv
or mv
doesn't matter.
The log
command takes a --follow
argument that continues history before a rename operation, i.e., it searches for similar content using the heuristics:
http://git-scm.com/docs/git-log
To lookup the full history, use the following command:
git log --follow ./path/to/file
Did you call your function properly? Ie. is the thing you pass as as a parameter really a string?
Otherwise, I don't see a problem with your code - the example below works as expected
function trim(str) {
return str.replace(/^\s+|\s+$/g,'');
}
trim(' hello '); // --> 'hello'
However, if you call your functoin with something non-string, you will indeed get the error above:
trim({}); // --> TypeError: str.replace is not a function
Array has no indexOf()
method.
Maybe this Apache Commons Lang ArrayUtils
method is what you are looking for
import org.apache.commons.lang3.ArrayUtils;
String[] colours = { "Red", "Orange", "Yellow", "Green" };
int indexOfYellow = ArrayUtils.indexOf(colours, "Yellow");
Assuming your sequence alternates increments between 1 and 3
numbers = [1]
while numbers[-1] < 100:
numbers.append(numbers[-1] + 1)
numbers.append(numbers[-1] + 3)
print ', '.join(map(str, numbers))
This could be easier to modify if your sequence is different but I think poke or BlaXpirit are nicer answers than mine.
Before you set your routes, add the code:
app.all('*', function(req, res, next) {
setTimeout(function() {
next();
}, 120000); // 120 seconds
});
Generally, it is never guaranteed that a system will only have one IP address, for example, you can have both an ethernet and wlan connections, and if you have an active VPN connection then you'll have yet another IP address.
On Linux, hostname -I
will list the current IP address(es). Relying on it always returning just one IP address will most likely not work as expected under some scenarios (i.e. a VPN link is up, multiple ethernet adapters, etc), so a more reliable way would be converting the result to an array and then loop over the elements:
ips=($(hostname -I))
for ip in "${ips[@]}"
do
echo $ip
done
Note: If
hostname -I
returns the IP both in IPv4 and IPv6 formats then you can use insteadhostname -I | cut -f1 -d' '
to only show the IPv4 IP.
On OSX, if you know the interface, you could use:
~$ ipconfig getifaddr en0
192.168.1.123
which will return just the IP address.
Or you could loop over possible interface names, starting with a suffix, i.e. en
:
for NUMBER in $(seq 0 5); do
ip=`ipconfig getifaddr en$NUMBER`
if [ -n "$ip" ]; then
myip="$ip"
break
fi
done
echo $myip
Also, getting the IP address becomes non-deterministic in case both a cable and wifi connections are established, when a machine has more than one ethernet interfaces, or when VPN tunnels are up.
If you need the external IP, then you can query a text-mode service, for example curl https://ipecho.net/plain
would return a plain text external IP.
A faster alternative is to query a known DNS server, e.g.:
dig @ns1-1.akamaitech.net ANY whoami.akamai.net +short
Just saying, this is also the value (kind of...) that is returned from php upon:
<?php var_dump(urlencode(PHP_EOL)); ?>
// Prints: string '%0D%0A' (length=6)-- used in 5.4.24 at least
Let's quote one of the spec's - http://tools.ietf.org/html/rfc7159#section-12
The The JavaScript Object Notation (JSON) Data Interchange Format Specification states:
JSON is a subset of JavaScript but excludes assignment and invocation.
Since JSON's syntax is borrowed from JavaScript, it is possible to use that language's "eval()" function to parse JSON texts. This generally constitutes an unacceptable security risk, since the text
could contain executable code along with data declarations. The same consideration applies to the use of eval()-like functions in any other programming language in which JSON texts conform to that
language's syntax.
So all answers which state, that functions are not part of the JSON standard are correct.
The official answer is: No, it is not valid to define functions in JSON results!
The answer could be yes, because "code is data" and "data is code". Even if JSON is used as a language independent data serialization format, a tunneling of "code" through other types will work.
A JSON string might be used to pass a JS function to the client-side browser for execution.
[{"data":[["1","2"],["3","4"]],"aFunction":"function(){return \"foo bar\";}"}]
This leads to question's like: How to "Execute JavaScript code stored as a string".
Be prepared, to raise your "eval() is evil" flag and stick your "do not tunnel functions through JSON" flag next to it.
Storm's answer is not correct. No hard feelings Storm, and apologies to the OP as I'm a bit late to the party here (wish I could have helped sooner, but I didn't run into the problem until today, or this stack overflow answer until I was figuring out a solution.)
The Visual C++ 2003 runtime was not available as a seperate download because it was included with the .NET 1.1 runtime.
If you install the .NET 1.1 runtime you will get msvcr71.dll installed, and in addition added to C:\WINDOWS\Microsoft.NET\Framework\v1.1.4322.
The .NET 1.1 runtime is available here: http://www.microsoft.com/downloads/en/details.aspx?familyid=262d25e3-f589-4842-8157-034d1e7cf3a3&displaylang=en (23.1 MB)
If you are looking for a file that ends with a "P" such as msvcp71.dll, this indicates that your file was compiled against a C++ runtime (as opposed to a C runtime), in some situations I noticed these files were only installed when I installed the full SDK. If you need one of these files, you may need to install the full .NET 1.1 SDK as well, which is available here: http://www.microsoft.com/downloads/en/details.aspx?FamilyID=9b3a2ca6-3647-4070-9f41-a333c6b9181d (106.2 MB)
After installing the SDK I now have both msvcr71.dll and msvcp71.dll in my System32 folder, and the application I'm trying to run (boomerang c++ decompiler) works fine without any missing DLL errors.
Also on a side note: be VERY aware of the difference between a Hotfix Update and a Regular Update. As noted in the linked KB932298 download (linked below by Storm): "Please be aware this Hotfix has not gone through full Microsoft product regression testing nor has it been tested in combination with other Hotfixes."
Hotfixes are NOT meant for general users, but rather users who are facing a very specific problem. As described in the article only install that Hotfix if you are have having specific daylight savings time issues with the rules that changed in 2007. -- Likely this was a pre-release for customers who "just couldn't wait" for the official update (probably for some business critical application) -- for regular users Windows Update should be all you need.
Thanks, and I hope this helps others who run into this issue!
I have made a PHP script which is designed to import large database dumps which have been generated by phpmyadmin or mysql dump (from cpanel) . It's called PETMI and you can download it here [project page] [gitlab page].
It works by splitting an. sql file into smaller files called a split and processing each split one at a time. Splits which fail to process can be processed manually by the user in phpmyadmin. This can be easily programmed as in sql dumps, each command is on a new line. Some things in sql dumps work in phpmyadmin imports but not in mysqli_query so those lines have been stripped from the splits.
It has been tested with a 1GB database. It has to be uploaded to an existing website. PETMI is open source and the sample code can be seen on Gitlab.
A moderator asked me to provide some sample code. I'm on a phone so excuse the formatting.
Here is the code that creates the splits.
//gets the config page
if (isset($_POST['register']) && $_POST['register'])
{
echo " <img src=\"loading.gif\">";
$folder = "split/";
include ("config.php");
$fh = fopen("importme.sql", 'a') or die("can't open file");
$stringData = "-- --------------------------------------------------------";
fwrite($fh, $stringData);
fclose($fh);
$file2 = fopen("importme.sql","r");
//echo "<br><textarea class=\"mediumtext\" style=\"width: 500px; height: 200px;\">";
$danumber = "1";
while(! feof($file2)){
//echo fgets($file2)."<!-- <br /><hr color=\"red\" size=\"15\"> -->";
$oneline = fgets($file2); //this is fgets($file2) but formatted nicely
//echo "<br>$oneline";
$findme1 = '-- --------------------------------------------------------';
$pos1 = strpos($oneline, $findme1);
$findme2 = '-- Table structure for';
$pos2 = strpos($oneline, $findme2);
$findme3 = '-- Dumping data for';
$pos3 = strpos($oneline, $findme3);
$findme4 = '-- Indexes for dumped tables';
$pos4 = strpos($oneline, $findme4);
$findme5 = '-- AUTO_INCREMENT for dumped tables';
$pos5 = strpos($oneline, $findme5);
if ($pos1 === false && $pos2 === false && $pos3 === false && $pos4 === false && $pos5 === false) {
// setcookie("filenumber",$i);
// if ($danumber2 == ""){$danumber2 = "0";} else { $danumber2 = $danumber2 +1;}
$ourFileName = "split/sql-split-$danumber.sql";
// echo "writing danumber is $danumber";
$ourFileHandle = fopen($ourFileName, 'a') or die("can't edit file. chmod directory to 777");
$stringData = $oneline;
$stringData = preg_replace("/\/[*][!\d\sA-Za-z@_='+:,]*[*][\/][;]/", "", $stringData);
$stringData = preg_replace("/\/[*][!]*[\d A-Za-z`]*[*]\/[;]/", "", $stringData);
$stringData = preg_replace("/DROP TABLE IF EXISTS `[a-zA-Z]*`;/", "", $stringData);
$stringData = preg_replace("/LOCK TABLES `[a-zA-Z` ;]*/", "", $stringData);
$stringData = preg_replace("/UNLOCK TABLES;/", "", $stringData);
fwrite($ourFileHandle, $stringData);
fclose($ourFileHandle);
} else {
//write new file;
if ($danumber == ""){$danumber = "1";} else { $danumber = $danumber +1;}
$ourFileName = "split/sql-split-$danumber.sql";
//echo "$ourFileName has been written with the contents above.\n";
$ourFileName = "split/sql-split-$danumber.sql";
$ourFileHandle = fopen($ourFileName, 'a') or die("can't edit file. chmod directory to 777");
$stringData = "$oneline";
fwrite($ourFileHandle, $stringData);
fclose($ourFileHandle);
}
}
//echo "</textarea>";
fclose($file2);
Here is the code that imports the split
<?php
ob_start();
// allows you to use cookies
include ("config.php");
//gets the config page
if (isset($_POST['register']))
{
echo "<div id**strong text**=\"sel1\"><img src=\"loading.gif\"></div>";

$dbname = $accesshost;
$dbhost = $username;
$dbuser = $password;
$dbpasswd = $database;
$table_prefix = $dbprefix;
//the above lines set variables with the user submitted information
//none were left blank! We continue...
//echo "$importme";
echo "<hr>";
$importme = "$_GET[file]";
$importme = file_get_contents($importme);
//echo "<b>$importme</b><br><br>";
$sql = $importme;
$findme1 = '-- Indexes for dumped tables';
$pos1 = strpos($importme, $findme1);

$pos2 = strpos($importme, $findme2);
$dbhost = '';
@set_time_limit(0);
if($pos1 !== false){
$splitted = explode("-- Indexes for table", $importme);
// print_r($splitted);
for($i=0;$i<count($splitted);$i++){

// echo "<b>$sql</b><hr>";
if($table_prefix !== 'phpbb_') $sql = preg_replace('/phpbb_/', $table_prefix, $sql);
$res = mysql_query($sql);
}
if(!$res) { echo '<b>error in query </b>', mysql_error(), '<br /><br>Try importing the split .sql file in phpmyadmin under the SQL tab.'; /* $i = $i +1; */ } else {
echo ("<meta http-equiv=\"Refresh\" content=\"0; URL=restore.php?page=done&file=$filename\"/>Thank You! You will be redirected");
}
} elseif($pos2 !== false){
$splitted = explode("-- AUTO_INCREMENT for table", $importme);
// print_r($splitted);
for($i=0;$i<count($splitted);$i++){
$sql = $splitted[$i];

// echo "<b>$sql</b><hr>";
if($table_prefix !== 'phpbb_') $sql = preg_replace('/phpbb_/', $table_prefix, $sql);

}
}
//echo 'done (', count($sql), ' queries).';
}

Credits: I combined multiple answers to get this one.
Read this https://docs.djangoproject.com/en/dev/howto/static-files/:
For local development, if you are using runserver or adding staticfiles_urlpatterns to your URLconf, you’re done with the setup – your static files will automatically be served at the default (for newly created projects) STATIC_URL of /static/.
And try:
~/tmp$ django-admin.py startproject myprj
~/tmp$ cd myprj/
~/tmp/myprj$ chmod a+x manage.py
~/tmp/myprj$ ./manage.py startapp myapp
Then add 'myapp'
to INSTALLED_APPS
(myprj/settings.py
).
~/tmp/myprj$ cd myapp/
~/tmp/myprj/myapp$ mkdir static
~/tmp/myprj/myapp$ echo 'alert("hello!");' > static/hello.js
~/tmp/myprj/myapp$ mkdir templates
~/tmp/myprj/myapp$ echo '<script src="{{ STATIC_URL }}hello.js"></script>' > templates/hello.html
Edit myprj/urls.py
:
from django.conf.urls import patterns, include, url
from django.views.generic import TemplateView
class HelloView(TemplateView):
template_name = "hello.html"
urlpatterns = patterns('',
url(r'^$', HelloView.as_view(), name='hello'),
)
And run it:
~/tmp/myprj/myapp$ cd ..
~/tmp/myprj$ ./manage.py runserver
It works!
You can also do what the "Service Reference" generated code does
public class ServiceXClient : ClientBase<IServiceX>, IServiceX
{
public ServiceXClient() { }
public ServiceXClient(string endpointConfigurationName) :
base(endpointConfigurationName) { }
public ServiceXClient(string endpointConfigurationName, string remoteAddress) :
base(endpointConfigurationName, remoteAddress) { }
public ServiceXClient(string endpointConfigurationName, EndpointAddress remoteAddress) :
base(endpointConfigurationName, remoteAddress) { }
public ServiceXClient(Binding binding, EndpointAddress remoteAddress) :
base(binding, remoteAddress) { }
public bool ServiceXWork(string data, string otherParam)
{
return base.Channel.ServiceXWork(data, otherParam);
}
}
Where IServiceX is your WCF Service Contract
Then your client code:
var client = new ServiceXClient(new WSHttpBinding(SecurityMode.None), new EndpointAddress("http://localhost:911"));
client.ServiceXWork("data param", "otherParam param");
I can't believe nobody suggested this:
int i = 9;
i.ToString("D2"); // Will give you the string "09"
or
i.ToString("D8"); // Will give you the string "00000009"
If you want hexadecimal:
byte b = 255;
b.ToString("X2"); // Will give you the string "FF"
You can even use just "C" to display as currency if you locale currency symbol. See here: https://docs.microsoft.com/en-us/dotnet/api/system.int32.tostring?view=netframework-4.7.2#System_Int32_ToString_System_String_
Here's a simple function that serves to explain the usage:
def print_wrap(arg1, *args, **kwargs):

print(args)
print(kwargs)
print(arg1, *args, **kwargs)
Any arguments that are not specified in the function definition will be put in the args
list, or the kwargs
list, depending on whether they are keyword arguments or not:
>>> print_wrap('one', 'two', 'three', end='blah', sep='--')
one
('two', 'three')
{'end': 'blah', 'sep': '--'}
one--two--threeblah
If you add a keyword argument that never gets passed to a function, an error will be raised:
>>> print_wrap('blah', dead_arg='anything')
TypeError: 'dead_arg' is an invalid keyword argument for this function
The answer to this question in 2020 is IT DOESN'T WORK AT ALL NOW.
This should help,
String s = "This is a sample sentence";
String[] words = s.split(" ");
this will make an array with elements as the string separated by " ".
Line by line
int [] v = Stream.of(line.split(",\\s+"))
.mapToInt(Integer::parseInt)
.toArray();
(A==B).all()
test if all values of array (A==B) are True.
Note: maybe you also want to test A and B shape, such as A.shape == B.shape
Special cases and alternatives (from dbaupp's answer and yoavram's comment)
It should be noted that:
A
or B
is empty and the other one contains a single element, then it return True
. For some reason, the comparison A==B
returns an empty array, for which the all
operator returns True
.A
and B
don't have the same shape and aren't broadcastable, then this approach will raise an error.In conclusion, if you have a doubt about A
and B
shape or simply want to be safe: use one of the specialized functions:
np.array_equal(A,B) # test if same shape, same elements values
np.array_equiv(A,B) # test if broadcastable shape, same elements values
np.allclose(A,B,...) # test if same shape, elements have close enough values
The current state of a socket is determined by 'keep-alive' activity. In your case, this is possible that when you are issuing the send
call, the keep-alive
activity tells that the socket is active and so the send
call will write the required data (40 bytes) in to the buffer and returns without giving any error.
When you are sending a bigger chunk, the send call goes in to blocking state.
The send man page also confirms this:
When the message does not fit into the send buffer of the socket, send() normally blocks, unless the socket has been placed in non-blocking I/O mode. In non-blocking mode it would return EAGAIN in this case
So, while blocking for the free available buffer, if the caller is notified (by keep-alive mechanism) that the other end is no more present, the send call will fail.
Predicting the exact scenario is difficult with the mentioned info, but I believe, this should be the reason for you problem.
I've had success with using white-space: nowrap; on the outer container, display: inline-block; on the inner containers, and then (in my case since I wanted the second one to word-wrap) white-space: normal; on the inner ones.
Assertions are a development-phase tool to catch bugs in your code. They're designed to be easily removed, so they won't exist in production code. So assertions are not part of the "solution" that you deliver to the customer. They're internal checks to make sure that the assumptions you're making are correct. The most common example is to test for null. Many methods are written like this:
void doSomething(Widget widget) {
if (widget != null) {
widget.someMethod(); // ...
... // do more stuff with this widget
}
}
Very often in a method like this, the widget should simply never be null. So if it's null, there's a bug in your code somewhere that you need to track down. But the code above will never tell you this. So in a well-intentioned effort to write "safe" code, you're also hiding a bug. It's much better to write code like this:
/**
* @param Widget widget Should never be null
*/
void doSomething(Widget widget) {
assert widget != null;
widget.someMethod(); // ...
... // do more stuff with this widget
}
This way, you will be sure to catch this bug early. (It's also useful to specify in the contract that this parameter should never be null.) Be sure to turn assertions on when you test your code during development. (And persuading your colleagues to do this, too is often difficult, which I find very annoying.)
Now, some of your colleagues will object to this code, arguing that you should still put in the null check to prevent an exception in production. In that case, the assertion is still useful. You can write it like this:
void doSomething(Widget widget) {
assert widget != null;
if (widget != null) {
widget.someMethod(); // ...
... // do more stuff with this widget
}
}
This way, your colleagues will be happy that the null check is there for production code, but during development, you're no longer hiding the bug when widget is null.
Here's a real-world example: I once wrote a method that compared two arbitrary values for equality, where either value could be null:
/**
* Compare two values using equals(), after checking for null.
* @param thisValue (may be null)
* @param otherValue (may be null)
* @return True if they are both null or if equals() returns true
*/
public static boolean compare(final Object thisValue, final Object otherValue) {
boolean result;
if (thisValue == null) {
result = otherValue == null;
} else {
result = thisValue.equals(otherValue);
}
return result;
}
This code delegates the work of the equals()
method in the case where thisValue is not null. But it assumes the equals()
method correctly fulfills the contract of equals()
by properly handling a null parameter.
A colleague objected to my code, telling me that many of our classes have buggy equals()
methods that don't test for null, so I should put that check into this method. It's debatable if this is wise, or if we should force the error, so we can spot it and fix it, but I deferred to my colleague and put in a null check, which I've marked with a comment:
public static boolean compare(final Object thisValue, final Object otherValue) {
boolean result;
if (thisValue == null) {
result = otherValue == null;
} else {
result = otherValue != null && thisValue.equals(otherValue); // questionable null check
}
return result;
}
The additional check here, other != null
, is only necessary if the equals()
method fails to check for null as required by its contract.
Rather than engage in a fruitless debate with my colleague about the wisdom of letting the buggy code stay in our code base, I simply put two assertions in the code. These assertions will let me know, during the development phase, if one of our classes fails to implement equals()
properly, so I can fix it:
public static boolean compare(final Object thisValue, final Object otherValue) {
boolean result;
if (thisValue == null) {
result = otherValue == null;
assert otherValue == null || otherValue.equals(null) == false;
} else {
result = otherValue != null && thisValue.equals(otherValue);
assert thisValue.equals(null) == false;
}
return result;
}
The important points to keep in mind are these:
Assertions are development-phase tools only.
The point of an assertion is to let you know if there's a bug, not just in your code, but in your code base. (The assertions here will actually flag bugs in other classes.)
Even if my colleague was confident that our classes were properly written, the assertions here would still be useful. New classes will be added that might fail to test for null, and this method can flag those bugs for us.
In development, you should always turn assertions on, even if the code you've written doesn't use assertions. My IDE is set to always do this by default for any new executable.
The assertions don't change the behavior of the code in production, so my colleague is happy that the null check is there, and that this method will execute properly even if the equals()
method is buggy. I'm happy because I will catch any buggy equals()
method in development.
Also, you should test your assertion policy by putting in a temporary assertion that will fail, so you can be certain that you are notified, either through the log file or a stack trace in the output stream.
This code help me in Attachment sending....
$mail->AddAttachment($_FILES['file']['tmp_name'], $_FILES['file']['name']);
Replace your AddAttachment(...) Code with above code
There are several ways to do it This is the better way
res.download('/report-12345.pdf')
or in your case this might be
app.get('/download', function(req, res){
const file = `${__dirname}/upload-folder/dramaticpenguin.MOV`;
res.download(file); // Set disposition and send it.
});
If the children have FKs linking them to the parent, then you can use DELETE CASCADE on the parent.
e.g.
CREATE TABLE supplier
( supplier_id numeric(10) not null,
supplier_name varchar2(50) not null,
contact_name varchar2(50),
CONSTRAINT supplier_pk PRIMARY KEY (supplier_id)
);
CREATE TABLE products
( product_id numeric(10) not null,
supplier_id numeric(10) not null,
CONSTRAINT fk_supplier
FOREIGN KEY (supplier_id)
REFERENCES supplier(supplier_id)
ON DELETE CASCADE
);
Delete the supplier, and it will delate all products for that supplier
Basically, you should include the class' header file in the code where you want to use the class in the shared library. Then, when you link, use the '-l' flag to link your code with the shared library. Of course, this requires the .so to be where the OS can find it. See 3.5. Installing and Using a Shared Library
Using dlsym is for when you don't know at compile time which library you want to use. That doesn't sound like it's the case here. Maybe the confusion is that Windows calls the dynamically loaded libraries whether you do the linking at compile or run-time (with analogous methods)? If so, then you can think of dlsym as the equivalent of LoadLibrary.
If you really do need to dynamically load the libraries (i.e., they're plug-ins), then this FAQ should help.
I was using this two lines in the url and the template from the admin what i was changing to my need
url(r'^change-password/$', 'django.contrib.auth.views.password_change', {
'template_name': 'password_change_form.html'}, name="password-change"),

For the best measure of elapsed time (since Python 3.3), use time.perf_counter()
.
Return the value (in fractional seconds) of a performance counter, i.e. a clock with the highest available resolution to measure a short duration. It does include time elapsed during sleep and is system-wide. The reference point of the returned value is undefined, so that only the difference between the results of consecutive calls is valid.
For measurements on the order of hours/days, you don't care about sub-second resolution so use time.monotonic()
instead.
Return the value (in fractional seconds) of a monotonic clock, i.e. a clock that cannot go backwards. The clock is not affected by system clock updates. The reference point of the returned value is undefined, so that only the difference between the results of consecutive calls is valid.
In many implementations, these may actually be the same thing.
Before 3.3, you're stuck with time.clock()
.
On Unix, return the current processor time as a floating point number expressed in seconds. The precision, and in fact the very definition of the meaning of “processor time”, depends on that of the C function of the same name.
On Windows, this function returns wall-clock seconds elapsed since the first call to this function, as a floating point number, based on the Win32 function QueryPerformanceCounter(). The resolution is typically better than one microsecond.
New in Python 3.7 is PEP 564 -- Add new time functions with nanosecond resolution.
Use of these can further eliminate rounding and floating-point errors, especially if you're measuring very short periods, or your application (or Windows machine) is long-running.
Resolution starts breaking down on perf_counter()
after around 100 days. So for example after a year of uptime, the shortest interval (greater than 0) it can measure will be bigger than when it started.
time.clock
is now gone.
When I tried sharing a resource.resx file from one C# project with another C# project, I got this problem. The suggestion on moving the Form class to the beginning of its file wasn't appropriate. This is how I solved it. You essentially use a link from the second project to the first, then enable regeneration of the resource.designer.cs
file.
Properties/Resources.resx
fileProperties/Resources.resx
file as a LINK to the Properties folder in the second project. Don't add it to the root level of the project.Properties/Resources.designer.cs
!Resources.resx
, add ResXFileCodeGenerator
as the CustomToolResources.resx
and select "Run Custom Tool". This will generate a new designer.cs file.Note: I would avoid editing the resource.designer.cs file, as this is autogenerated.
I was looking for something similar and came across this. It looks like in the first option you mentioned
r = requests.get('<MY_URI>', auth=('<MY_TOKEN>'))
"auth" takes two parameters: username and password, so the actual statement should be
r=requests.get('<MY_URI>', auth=('<YOUR_USERNAME>', '<YOUR_PASSWORD>'))
In my case, there was no password, so I left the second parameter in auth field empty as shown below:
r=requests.get('<MY_URI', auth=('MY_USERNAME', ''))
Hope this helps somebody :)
For those stuck with "The requested resource is not available" in Java EE 7 and dynamic web module 3.x, maybe this could help: the "Create Servlet" wizard in Eclipse (tested in Mars) doesn't create the @Path annotation for the servlet class, but I had to include it to access successfuly to the public methods exposed.
Restarting SQL server will disconnect users. Easiest way I've found - good also if you want to take the server offline.
But for some very wierd reason the 'Take Offline' option doesn't do this reliably and can hang or confuse the management console. Restarting then taking offline works
Sometimes this is an option - if for instance you've stopped a webserver that is the source of the connections.
The android studio and Gradle version looks like very bad managed. And there's tons of version in-capability issues. And the error message is mostly clueless. For this particular issue. The closest answer is from "Jitendra Singh". Change the version to:
classpath 'com.android.tools.build:gradle:2.0.0'
But in my case: Android studio 2.2 RC, I still get another error:
Could not find matching constructor for: com.android.build.gradle.internal.LibraryTaskManager(org.gradle.api.internal.project.DefaultProject_Decorated, com.android.builder.core.AndroidBuilder, android.databinding.tool.DataBindingBuilder, com.android.build.gradle.LibraryExtension_Decorated, com.android.build.gradle.internal.SdkHandler, com.android.build.gradle.internal.DependencyManager, org.gradle.tooling.provider.model.internal.DefaultToolingModelBuilderRegistry)
So I went to the maven central to find the latest com.android.tools.build:gradle version which is 2.1.3 for now. So after change to
buildscript {
repositories {
mavenCentral()
}
dependencies {
classpath 'com.android.tools.build:gradle:2.1.3'
}
}
Solved my problem eventually.
One simple way to check your changes to that file in Tomcat 8 + is to open a browser to: http://localhost:8080/manager/text/list
<context:property-placeholder location="file:/apps/tomcat/ath/ath_conf/pcr.application.properties" />
This works for me. Local development machine path is C:\apps\tomcat\ath\ath_conf and in server /apps/tomcat/ath/ath_conf
Both works for me
I deleted file inside svn.simple
directory at below path on windows machine (Windows 7):
C:\Users\[user_name]\AppData\Roaming\Subversion\auth
Problem solved.
You can use this code
using (WebClient client = new WebClient()) {
Stream stream = client.OpenRead(imgUrl);
if (stream != null) {

ImageFormat imageFormat = ImageFormat.Jpeg;
if (bitmap.RawFormat.Equals(ImageFormat.Png)) {
imageFormat = ImageFormat.Png;
}
else if (bitmap.RawFormat.Equals(ImageFormat.Bmp)) {
imageFormat = ImageFormat.Bmp;
}
else if (bitmap.RawFormat.Equals(ImageFormat.Gif)) {
imageFormat = ImageFormat.Gif;
}
else if (bitmap.RawFormat.Equals(ImageFormat.Tiff)) {
imageFormat = ImageFormat.Tiff;
}
bitmap.Save(fileName, imageFormat);
stream.Flush();
stream.Close();
client.Dispose();
}
}

You should use double instead of float for precise calculations, and float instead of double when using less accurate calculations. Float contains only decimal numbers, but double contains an IEEE754 double-precision floating point number, making it easier to contain and computate numbers more accurately. Hope this helps.
Thanks to everyone that posted solutions, I combined multiple approaches to provide some more advanced disabled
functionality. Here is a gist, and the code is below.
This provides for multiple levels of defense so that Anchors marked as disable actually behave as such.
Using this approach, you get an anchor that you cannot:
- click
- tab to and hit return
- tabbing to it will move focus to the next focusable element
- it is aware if the anchor is subsequently enabled
1. Include this css, as it is the first line of defense. This assumes the selector you use is 'a.disabled'
a.disabled {
pointer-events: none;
cursor: default;
}
2. Next, instantiate this class such as (with optional selector):
$ ->
new AnchorDisabler()
Here is the coffescript class:
class AnchorDisabler
constructor: (selector = 'a.disabled') ->
$(selector).click(@onClick).keyup(@onKeyup).focus(@onFocus)
isStillDisabled: (ev) =>
### since disabled can be a class or an attribute, and it can be dynamically removed, always recheck on a watched event ###
target = $(ev.target)
return true if target.hasClass('disabled')
return true if target.attr('disabled') is 'disabled'
return false
onFocus: (ev) =>
### if an attempt is made to focus on a disabled element, just move it along to the next focusable one. ###
return unless @isStillDisabled(ev)
focusables = $(':focusable')
return unless focusables
current = focusables.index(ev.target)
next = (if focusables.eq(current + 1).length then focusables.eq(current + 1) else focusables.eq(0))
next.focus() if next
onClick: (ev) =>
# disabled could be dynamically removed
return unless @isStillDisabled(ev)
ev.preventDefault()
return false
onKeyup: (ev) =>
# 13 is the js key code for Enter, we are only interested in disabling that so get out fast
code = ev.keyCode or ev.which
return unless code is 13
# disabled could be dynamically removed
return unless @isStillDisabled(ev)
ev.preventDefault()
return false
No, Not at all.
Callbacks are simply Functions In JavaScript which are to be called and then executed after the execution of another function has finished. So how it happens?
Actually, In JavaScript, functions are itself considered as objects and hence as all other objects, even functions can be sent as arguments to other functions. The most common and generic use case one can think of is setTimeout() function in JavaScript.
Promises are nothing but a much more improvised approach of handling and structuring asynchronous code in comparison to doing the same with callbacks.
The Promise receives two Callbacks in constructor function: resolve and reject. These callbacks inside promises provide us with fine-grained control over error handling and success cases. The resolve callback is used when the execution of promise performed successfully and the reject callback is used to handle the error cases.
Two suggestions:
std::deque
instead of std::vector
for better performance in your specific case and use the method std::deque::pop_front()
.&
in std::vector<ScanRule>& topPriorityRules;
I am running eclipse from Ubuntu. Had this same problem and was able run the program through terminal. So I just moved the existing public static void main(String[] args) {
just below the class declaration (it got automatically formatted by eclipse) and the next launch was successful. Then moved the main method back to where it was before and it worked fine this time.
class Frame1 extends javax.swing.JFrame {
remove(previouspanel); //or getContentPane().removeAll();
add(newpanel); //or setContentPane(newpanel);
invalidate(); validate(); // or ((JComponent) getContentPane()).revalidate();
repaint(); //DO NOT FORGET REPAINT
}
Sometimes you can do the work without using the revalidation and sometimes without using the repaint.My advise use both.
Add a style with the attribute text-decoration:none;
:
There are a number of different ways of doing this.
Inline style:
<a href="xxx.html" style="text-decoration:none;">goto this link</a>
Inline stylesheet:
<html>
<head>
<style type="text/css">
a {
text-decoration:none;
}
</style>
</head>
<body>
<a href="xxx.html">goto this link</a>
</body>
</html>
External stylesheet:
<html>
<head>
<link rel="Stylesheet" href="stylesheet.css" />
</head>
<body>
<a href="xxx.html">goto this link</a>
</body>
</html>
stylesheet.css:

For me maven was downloading the dependency but was unable to add it to the classpath. I saw my .classpath of the project,it didnt have any maven-related entry. When I added
<classpathentry kind="con" path="org.eclipse.m2e.MAVEN2_CLASSPATH_CONTAINER"/>
the issue got resolved for me.
Lightweight Directory Access Protocol or LDAP, is a standards based specification for interacting with directory data. Directory Services can implement support of LDAP to provide interoperability among 3rd party applications.
Active Directory is Microsoft's implementation of a directory service that, among other protocols, supports LDAP to query it's data.
While it supports LDAP, Active Directory provides a host of extensions and conveniences, such as password expiration and account lockout.
Move all of your state and your handleClick
function from Header
to your MainWrapper
component.
Then pass values as props to all components that need to share this functionality.
class MainWrapper extends React.Component {
constructor() {
super();
this.state = {
sidbarPushCollapsed: false,
profileCollapsed: false
};
this.handleClick = this.handleClick.bind(this);
}
handleClick() {
this.setState({
sidbarPushCollapsed: !this.state.sidbarPushCollapsed,
profileCollapsed: !this.state.profileCollapsed
});
}
render() {
return (
//...
<Header
handleClick={this.handleClick}
sidbarPushCollapsed={this.state.sidbarPushCollapsed}
profileCollapsed={this.state.profileCollapsed} />
);
Then in your Header's render() method, you'd use this.props
:
<button type="button" id="sidbarPush" onClick={this.props.handleClick} profile={this.props.profileCollapsed}>
void main(){
var x = "4";
int number = int.parse(x);//STRING to INT
var y = "4.6";
double doubleNum = double.parse(y);//STRING to DOUBLE
var z = 55;
String myStr = z.toString();//INT to STRING
}
int.parse() and double.parse() can throw an error when it couldn't parse the String
Simple use native editBarButton like this
self.navigationItem.rightBarButtonItem = self.editButtonItem;
[self.navigationItem.rightBarButtonItem setAction:@selector(editBarBtnPressed)];
and then
- (void)editBarBtnPressed {
if ([infoTable isEditing]) {
[self.editButtonItem setTitle:@"Edit"];
[infoTable setEditing:NO animated:YES];
}
else {
[self.editButtonItem setTitle:@"Done"];
[infoTable setEditing:YES animated:YES];
}
}
Have fun...!!!
For example :
<div style="height:100px; width:100px; background:#000000"></div>
_x000D_
here.
you give css to div of height and width having 100px and background as black.
PS : try to avoid inline-css you can make external CSS and import in your html file.
you can refer here for CSS
hope this helps.
Thanks for the above codes! - I tried several options and this was the ticket. I had problems in that preventDefault was preventing scrolling on the ipad - I am now testing for draggable items and it works great so far.
if (event.target.id == 'draggable_item' ) {
event.preventDefault();
}
In my case, the patch was generated perfectly fine by IDEA, however, I edited the patch and saved it which changed CRLF to LF and then the patch stopped working. Curiously, converting it back to CRLF did not work. I noticed in VI editor, that even after setting to DOS format, the '^M' were not added to the end of lines. This forced me to only make changes in VI, so that the EOLs were preserved.
This may apply to you, if you make changes in a non-Windows environment to a patch covering changes between two versions both coming from Windows environment. You want to be careful how you edit such files.
BTW ignore-whitespace
did not help.
Here's some reusable css that will preserve the height of each element without using position: absolute
:
.stack {
display: grid;
}
.stack > * {
grid-row: 1;
grid-column: 1;
}
The first element in your stack
is the background, and the second is the foreground.
With MoQ, you can mock concrete classes:
var mocked = new Mock<MyConcreteClass>();
but this allows you to override virtual
code (methods and properties).
I found that most answers are incomplete here. In case anyone else is still looking for this:
A much computationally simpler method, if you already know a point inside the polygon:
Choose any line segment from the original polygon, points and their coordinates in that order.
Add a known "inside" point, and form a triangle.
Calculate CW or CCW as suggested here with those three points.
SQL Server 2012 above, I prefer use format() function, more simplify.
SELECT format(date,'MM.yyyy') AS Mjesec, SUM(marketingExpense) AS SumaMarketing, SUM(revenue) AS SumaZarada
FROM [Order]
WHERE (idCustomer = 1) AND (date BETWEEN '2001-11-3' AND '2011-11-3')
GROUP BY format(date,'MM.yyyy')
To remove the scrollbar add the following CSS:
select[multiple] {
overflow-y: auto;
}
Here's a snippet:
select[multiple] {_x000D_
overflow-y: auto;_x000D_
}
_x000D_
<select>_x000D_
<option value="1">One</option>_x000D_
<option value="2">Two</option>_x000D_
<option value="3">Three</option>_x000D_
</select>_x000D_
_x000D_
<select multiple size="3">_x000D_
<option value="1">One</option>_x000D_
<option value="2">Two</option>_x000D_
<option value="3">Three</option>_x000D_
</select>
_x000D_
To create icon you can use Glyphicon in Bootstrap:
<a href="#" class="btn btn-info btn-sm">
<span class="glyphicon glyphicon-menu-hamburger"></span>
</a>
And then control size of icon in css:
.glyphicon-menu-hamburger {
font-size: npx;
}
Since you are using Mi phone which has MIUI
try this
go to Developer options, scroll down to find 'Turn on MIUI optimization' & disable it. Your Phone will be rebooted
check now
If you are using any other android phone, which has a custom skin/UI on top of android OS, then try disabling the optimization provided by that UI and check.
(usually you can find that in 'Developer options')
You can create the PDF document using PdfSharp. It is an open source .NET library.
When trying to print the document it get worse. I have looked allover for a open source way of doing it. There are some ways do do it using AcroRd32.exe but it all depends on the version, and it cannot be done without acrobat reader staying open.
I finally ended up using VintaSoftImaging.NET SDK. It costs some money but is much cheaper than the alternative and it solves the problem really easy.
var doc = new Vintasoft.Imaging.Print.ImagePrintDocument { DocumentName = @"C:\Test.pdf" };
doc.Print();
That just prints to the default printer without showing. There are several alternatives and options.
I was in need of copying the data from one workbook to another using VBA. The requirement was as mentioned below 1. On pressing an Active X button open the dialogue to select the file from which the data needs to be copied. 2. On clicking OK the value should get copied from a cell / range to currently working workbook.
I did not want to use the open function because it opens the workbook which will be annoying

Update Bootstrap 4
Bootstrap 4 has utility classes that make it easier to create a full screen carousel. For example, use the min-vh-100
class on the carousel-item
content...
<div class="carousel slide" data-ride="carousel">
<div class="carousel-inner bg-info" role="listbox">
<div class="carousel-item active">
<div class="d-flex align-items-center justify-content-center min-vh-100">
<h1 class="display-1">ONE</h1>
</div>
</div>
</div>
</div>
This works to make the carousel items full screen, but carousel items that contain images or videos that have a specific size & aspect ratio require further consideration.
Since the viewport h/w ratio is likely to be different than the image or video h/w ratio, usually background images or object-fit
are commonly used to size images and videos to "full screen". For videos, use the Bootstrap responsive embed classes as needed for the video ratio (21:9, 19:9, etc...).

Original answer (Bootstrap 3)
Make sure the img inside the carousel item is set to height and width 100%. You also have to make sure the carousel and any of the .item containers (html,body) are 100%...
html,body{height:100%;}
.carousel,.item,.active{height:100%;}
.carousel-inner{height:100%;}

Here's an example for Bootstrap 3.x: http://www.codeply.com/go/2tVXo3mAtV
Which specific index? If you want 'Add New' to be first on the dropdownlist you can add it though the code like this:
<asp:DropDownList ID="DropDownList1" AppendDataBoundItems="true" runat="server">
<asp:ListItem Text="Add New" Value="0" />
</asp:DropDownList>
If you want to add it at a different index, maybe the last then try:
ListItem lst = new ListItem ( "Add New" , "0" );
DropDownList1.Items.Insert( DropDownList1.Items.Count-1 ,lst);
The ist and 2nd answer are good but if anybody is looking for having a script or If you want dynamic i.e (db/username/password in variable) then here:
#!/bin/bash
DB="mydb"
USER="user1"
PASS="pass_bla"
mysql -uroot -prootpassword -e "CREATE DATABASE $DB CHARACTER SET utf8 COLLATE utf8_general_ci";
mysql -uroot -prootpassword -e "CREATE USER $USER@'127.0.0.1' IDENTIFIED BY '$PASS'";
mysql -uroot -prootpassword -e "GRANT SELECT, INSERT, UPDATE ON $DB.* TO '$USER'@'127.0.0.1'";
Why it can be good to store pictures in the database an not in a catalog on the web server.
You have made an application with lots of pictures stored in a folder on the server, that the client has used for years.
Now they come to you. They server has been destroyed and they need to restore it on a new server. They have no access to the old server anymore. The only backup they have is the database backup.
You have of course the source and can simple deploy it to the new server, install SqlServer and restore the database. But now all the pictures are gone.
If you have saved the pictures in SqlServer everything will work as before.
Just my 2 cents.
Make the script executable by the user "Kev" and then remove the try it running through the command
sh kev@server1 /test/foo.sh
test.split("\\|",999);
Specifing a limit or max will be accurate for examples like: "boo|||a" or "||boo|" or " |||"
But test.split("\\|");
will return different length strings arrays for the same examples.

With the upcoming release of iOS 7 you will notice that the "standard" icon radius has been increased. So try to do what Apple and I suggested with this answer.
It appears that for a 120px icon the formula that best represents its shape on iOS 7 is the following superellipse:
|x/120|^5 + |y/120|^5 = 1
Obviously you can change the 120
number with the desired icon size to get the corresponding function.

You should provide an image that has 90° corners (it’s important to avoid cropping the corners of your icon—iOS does that for you when it applies the corner-rounding mask) (Apple Documentation)
The best approach is not rounding the corners of your icons at all. If you set your icon as a square icon, iOS will automatically overlay the icon with a predefined mask that will set the appropriate rounded corners.
If you manually set rounded corners for your icons, they will probably look broken in this or that device, because the rounding mask happens to slightly change from an iOS version to another. Sometimes your icons will be slightly larger, sometimes (sigh) slightly smaller. Using a square icon will free you from this burden, and you will be sure to have an always up-to-date and good looking icon for your app.
This approach is valid for each icon size (iPhone/iPod/iPad/retina), and also for the iTunes artwork. I followed this approach a couple of times, and if you want I can post you a link to an app that uses native square icons.
Edit
To better understand this answer, please refer to the official Apple documentation about iOS icons. In this page it is clearly stated that a square icon will automatically get these things when displayed on an iOS device:
So, you can achieve whatever effect you want just drawing a plain square icon and filling content in it. The final corner radius will be something similar to what the other answers here are saying, but this will never be guaranteed, since those numbers are not part of the official Apple documentation on iOS. They ask you to draw square icons, so ... why not?
If you want to take advantage of the 60FPS smoothness that the "transform" property offers, you can combine the two:
@keyframes changewidth {
from {
transform: scaleX(1);
}
to {
transform: scaleX(2);
}
}
div {
animation-duration: 0.1s;
animation-name: changewidth;
animation-iteration-count: infinite;
animation-direction: alternate;
}
More explanation on why transform offers smoother transitions here: https://medium.com/outsystems-experts/how-to-achieve-60-fps-animations-with-css3-db7b98610108
If you need to find the max/min of a hash, you can use #max_by
or #min_by
people = {'joe' => 21, 'bill' => 35, 'sally' => 24}
people.min_by { |name, age| age } #=> ["joe", 21]
people.max_by { |name, age| age } #=> ["bill", 35]
IF CHARINDEX('TextToSearch',@TextWhereISearch, 0) > 0 => TEXT EXISTS
IF PATINDEX('TextToSearch', @TextWhereISearch) > 0 => TEXT EXISTS
Additionally we can also use LIKE but I usually don't use LIKE.
This can be done using HTML5, but will only work in browsers that support it. Here's an example.
Bear in mind you'll need an alternative method for browsers that don't support this. I've had a lot of success with this plugin, which takes a lot of the work out of your hands.
For Unescape You can simply use this functions:
System.Text.RegularExpressions.Regex.Unescape(string)
System.Uri.UnescapeDataString(string)
I suggest using this method (It works better with UTF-8):
UnescapeDataString(string)
If you host the server yourself, in the php.ini file remove the semicolon in front of the extension extension=php_mysqli.dll
Sometimes it is very convenient to use stringstream to convert between strings and other numerical types. The usage of stringstream
is similar to the usage of iostream
, so it is not a burden to learn.
Stringstreams can be used to both read strings and write data into strings. It mainly functions with a string buffer, but without a real I/O channel.
The basic member functions of stringstream class are
str()
, which returns the contents of its buffer in string type.
str(string)
, which set the contents of the buffer to the string argument.
Here is an example of how to use string streams.
ostringstream os;
os << "dec: " << 15 << " hex: " << std::hex << 15 << endl;
cout << os.str() << endl;
The result is dec: 15 hex: f
.
istringstream
is of more or less the same usage.
To summarize, stringstream is a convenient way to manipulate strings like an independent I/O device.
FYI, the inheritance relationships between the classes are:
Very old question but providing some additional information which may help someone else. I also encountered same error and I was using ojdbc14.jar with 12.1.0.2 Oracle Database. On Oracle official web page this information is listed that which version supports which database drivers. Here is the link and it appears that with Oracle 12c and Java 7 or 8 the correct version is ojdbc7.jar.
In the ojdbc6.jar is for 11.2.0.4.
See ?boxplot
for all the help you need.
outline: if ‘outline’ is not true, the outliers are not drawn (as
points whereas S+ uses lines).
boxplot(x,horizontal=TRUE,axes=FALSE,outline=FALSE)
And for extending the range of the whiskers and suppressing the outliers inside this range:
range: this determines how far the plot whiskers extend out from the
box. If ‘range’ is positive, the whiskers extend to the most
extreme data point which is no more than ‘range’ times the
interquartile range from the box. A value of zero causes the
whiskers to extend to the data extremes.
# change the value of range to change the whisker length
boxplot(x,horizontal=TRUE,axes=FALSE,range=2)
