you also coud try this:
<select ng-model="selectedItem" ng-change="update()">
<option ng-repeat="item in items"
ng-selected="selectedItem == item.Id" value="{{item.Id}}">
{{item.Name}}
</option>
</select>
Actually, there are some situations which the throw
statment will not preserve the StackTrace information. For example, in the code below:
try
{
int i = 0;
int j = 12 / i; // Line 47
int k = j + 1;
}
catch
{
// do something
// ...
throw; // Line 54
}
The StackTrace will indicate that line 54 raised the exception, although it was raised at line 47.
Unhandled Exception: System.DivideByZeroException: Attempted to divide by zero.
at Program.WithThrowIncomplete() in Program.cs:line 54
at Program.Main(String[] args) in Program.cs:line 106
In situations like the one described above, there are two options to preseve the original StackTrace:
Calling the Exception.InternalPreserveStackTrace
As it is a private method, it has to be invoked by using reflection:
private static void PreserveStackTrace(Exception exception)
{
MethodInfo preserveStackTrace = typeof(Exception).GetMethod("InternalPreserveStackTrace",
BindingFlags.Instance | BindingFlags.NonPublic);
preserveStackTrace.Invoke(exception, null);
}
I has a disadvantage of relying on a private method to preserve the StackTrace information. It can be changed in future versions of .NET Framework. The code example above and proposed solution below was extracted from Fabrice MARGUERIE weblog.
Calling Exception.SetObjectData
The technique below was suggested by Anton Tykhyy as answer to In C#, how can I rethrow InnerException without losing stack trace question.
static void PreserveStackTrace (Exception e)
{
var ctx = new StreamingContext (StreamingContextStates.CrossAppDomain) ;
var mgr = new ObjectManager (null, ctx) ;
var si = new SerializationInfo (e.GetType (), new FormatterConverter ()) ;
e.GetObjectData (si, ctx) ;
mgr.RegisterObject (e, 1, si) ; // prepare for SetObjectData
mgr.DoFixups () ; // ObjectManager calls SetObjectData
// voila, e is unmodified save for _remoteStackTraceString
}
Although, it has the advantage of relying in public methods only it also depends on the following exception constructor (which some exceptions developed by 3rd parties do not implement):
protected Exception(
SerializationInfo info,
StreamingContext context
)
In my situation, I had to choose the first approach, because the exceptions raised by a 3rd-party library I was using didn't implement this constructor.
Since you are using bootstrap and you want alternating row colors for every screen sizes you need to write separate style rules for all the screen sizes.
/* For small screen */
.row :nth-child(even){
background-color: #dcdcdc;
}
.row :nth-child(odd){
background-color: #aaaaaa;
}
/* For medium screen */
@media (min-width: 768px) {
.row :nth-child(4n), .row :nth-child(4n-1) {
background: #dcdcdc;
}
.row :nth-child(4n-2), .row :nth-child(4n-3) {
background: #aaaaaa;
}
}
/* For large screen */
@media (min-width: 992px) {
.row :nth-child(6n), .row :nth-child(6n-1), .row :nth-child(6n-2) {
background: #dcdcdc;
}
.row :nth-child(6n-3), .row :nth-child(6n-4), .row :nth-child(6n-5) {
background: #aaaaaa;
}
}
Working FIDDLE
I have also included the bootstrap CSS here.
Maybe:
crimefile = open(fileName, 'r')
yourResult = [line.split(',') for line in crimefile.readlines()]
$(document).ready(function(){
$('.lbOn').click();
});
Suppose this would work too.
There's a kind of hack-tastic way to do it if you have php enabled on your server. Change this line:
url: 'http://www.ecb.europa.eu/stats/eurofxref/eurofxref-daily.xml',
to this line:
url: '/path/to/phpscript.php',
and then in the php script (if you have permission to use the file_get_contents() function):
<?php
header('Content-type: application/xml');
echo file_get_contents("http://www.ecb.europa.eu/stats/eurofxref/eurofxref-daily.xml");
?>
Php doesn't seem to mind if that url is from a different origin. Like I said, this is a hacky answer, and I'm sure there's something wrong with it, but it works for me.
Edit: If you want to cache the result in php, here's the php file you would use:
<?php
$cacheName = 'somefile.xml.cache';
// generate the cache version if it doesn't exist or it's too old!
$ageInSeconds = 3600; // one hour
if(!file_exists($cacheName) || filemtime($cacheName) > time() + $ageInSeconds) {
$contents = file_get_contents('http://www.ecb.europa.eu/stats/eurofxref/eurofxref-daily.xml');
file_put_contents($cacheName, $contents);
}
$xml = simplexml_load_file($cacheName);
header('Content-type: application/xml');
echo $xml;
?>
Caching code take from here.
If you want to load the partial view directly inside the main view you could use the Html.Action
helper:
@Html.Action("Load", "Home")
or if you don't want to go through the Load action use the HtmlPartialAsync helper:
@await Html.PartialAsync("_LoadView")
If you want to use Ajax.ActionLink
, replace your Html.ActionLink
with:
@Ajax.ActionLink(
"load partial view",
"Load",
"Home",
new AjaxOptions { UpdateTargetId = "result" }
)
and of course you need to include a holder in your page where the partial will be displayed:
<div id="result"></div>
Also don't forget to include:
<script src="@Url.Content("~/Scripts/jquery.unobtrusive-ajax.js")" type="text/javascript"></script>
in your main view in order to enable Ajax.*
helpers. And make sure that unobtrusive javascript is enabled in your web.config (it should be by default):
<add key="UnobtrusiveJavaScriptEnabled" value="true" />
If you have installed using Homebrew, the below command should be enough.
brew services restart postgresql
This sometimes might not work. In that case, the below two commands should definitely work:
rm /usr/local/var/postgres/postmaster.pid
pg_ctl -D /usr/local/var/postgres start
You can not sort TreeMap on values.
A Red-Black tree based NavigableMap implementation. The map is sorted according to the natural ordering of its keys, or by a Comparator provided at map creation time, depending on which constructor is used You will need to provide
comparator
forComparator<? super K>
so your comparator should compare on keys.
To provide sort on values you will need SortedSet. Use
SortedSet<Map.Entry<String, Double>> sortedset = new TreeSet<Map.Entry<String, Double>>(
new Comparator<Map.Entry<String, Double>>() {
@Override
public int compare(Map.Entry<String, Double> e1,
Map.Entry<String, Double> e2) {
return e1.getValue().compareTo(e2.getValue());
}
});
sortedset.addAll(myMap.entrySet());
To give you an example
SortedMap<String, Double> myMap = new TreeMap<String, Double>();
myMap.put("a", 10.0);
myMap.put("b", 9.0);
myMap.put("c", 11.0);
myMap.put("d", 2.0);
sortedset.addAll(myMap.entrySet());
System.out.println(sortedset);
Output:
[d=2.0, b=9.0, a=10.0, c=11.0]
def chunker(seq, size):
return (seq[pos:pos + size] for pos in range(0, len(seq), size))
# (in python 2 use xrange() instead of range() to avoid allocating a list)
Works with any sequence:
text = "I am a very, very helpful text"
for group in chunker(text, 7):
print(repr(group),)
# 'I am a ' 'very, v' 'ery hel' 'pful te' 'xt'
print '|'.join(chunker(text, 10))
# I am a ver|y, very he|lpful text
animals = ['cat', 'dog', 'rabbit', 'duck', 'bird', 'cow', 'gnu', 'fish']
for group in chunker(animals, 3):
print(group)
# ['cat', 'dog', 'rabbit']
# ['duck', 'bird', 'cow']
# ['gnu', 'fish']
I believe fcntl()
is a POSIX function. Where as ioctl()
is a standard UNIX thing. Here is a list of POSIX io. ioctl()
is a very kernel/driver/OS specific thing, but i am sure what you use works on most flavors of Unix. some other ioctl()
stuff might only work on certain OS or even certain revs of it's kernel.
i think it's just the debugger making it simple. Note that a case and "if list" are not ultimately the same. There is is a reason why case blocks normally end with "break". The case stmt actually looks something like this when broken down in assembly.
if myObject.GetType() == type of Car
GOTO START_CAR
else if myObject.GetType() == type of Bike
GOTO START_BIKE
LABEL START_CAR
//do something car
GOTO END
LABEL START_BIKE
//do something bike
GOTO END
LABEL END
If you don't have the break, then the case blocks would be missing the "GOTO END" stmts, and in fact if you landed in the "car" case you'd actually run both sections
//do something car
//do something bike
GOTO END

To send json to the server, you first have to create json
function sendData() {
$.ajax({
url: '/helloworld',
type: 'POST',
contentType: 'application/json',
data: JSON.stringify({
name:"Bob",
...
}),
dataType: 'json'
});
}
This is how you would structure the ajax request to send the json as a post var.
function sendData() {
$.ajax({
url: '/helloworld',
type: 'POST',
data: { json: JSON.stringify({
name:"Bob",
...
})},
dataType: 'json'
});
}
The json will now be in the json
post var.
I assumed openjdk8 would work with tomcat8 but I had to remove it and keep openjdk7 only, this fixed the issue in my case. I really don't know why or if there is something else I could have done.
The problem here is that the length of your array is undefined, and this confuses VBA if the array is explicitly defined as a string. Variants, however, seem to be able to resize as needed (because they hog a bunch of memory, and people generally avoid them for a bunch of reasons).
The following code works just fine, but it's a bit manual compared to some of the other languages out there:
Dim SomeArray(3) As String
SomeArray(0) = "Zero"
SomeArray(1) = "One"
SomeArray(2) = "Two"
SomeArray(3) = "Three"
Enter super user mode, and cd into the directory that you are not permissioned to go into. Sudo requires administrator password.
sudo su
cd directory
You can use the non-standard FROM clause.
UPDATE b
SET column1 = a.column1,
column2 = a.column2,
column3 = a.column3
FROM a
WHERE a.id = b.id
AND b.id = 1

If anyone is still wondering, on the newer versions of windows you can use powershell:
powershell.exe -command "& {$pshost = Get-Host;$pswindow = $pshost.UI.RawUI;$newsize = $pswindow.BufferSize;$newsize.height = 150;$pswindow.buffersize = $newsize;}"
The version I'm using I think is the good one, since is the exact same as the Android Developer Docs, except for the name of the string, they used "view" and I used "webview", for the rest is the same
No, it is not.
The one that is new to the N Developer Preview has this method signature:
public boolean shouldOverrideUrlLoading(WebView view, WebResourceRequest request)
The one that is supported by all Android versions, including N, has this method signature:
public boolean shouldOverrideUrlLoading(WebView view, String url)
So why should I do to make it work on all versions?
Override the deprecated one, the one that takes a String
as the second parameter.
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");
Install file loader first:
$ npm install file-loader --save-dev
And add this rule in webpack.config.js
{
test: /\.(png|jpg|gif)$/,
use: [{
loader: 'file-loader',
options: {}
}]
}
It's going to be locale-dependent. Different locale, different default encoding.
Got the same error when tried to export a large Excel file (~150.000 rows) Fixed with the following code
Application xlApp = new Application();
xlApp.DefaultSaveFormat = XlFileFormat.xlOpenXMLWorkbook;
I know his is super old but it blows my mind no one recommended just passing cookies from one domain to the other. As you are using subdomains you can share cookies from a base domain to all subdomains just by setting cookies to the url .basedomain.com
Then you can share whatever data you need through the cookies.
The easiest way i found was to create a tiny javascript function tied to your form :
function enablePath() {
document.getElementById('select_name').disabled= "";
}
and you call it in your form here :
<form action="act.php" method="POST" name="form_name" onSubmit="enablePath();">
Or you can call it in the function you use to check your form :)
The easiest way is to just interrupt it with the usual Ctrl-C
(SIGINT).
try:
while True:
do_something()
except KeyboardInterrupt:
pass
Since Ctrl-C
causes KeyboardInterrupt
to be raised, just catch it outside the loop and ignore it.
[Updated to adapt to modern pandas
, which has isnull
as a method of DataFrame
s..]
You can use isnull
and any
to build a boolean Series and use that to index into your frame:
>>> df = pd.DataFrame([range(3), [0, np.NaN, 0], [0, 0, np.NaN], range(3), range(3)])
>>> df.isnull()
0 1 2
0 False False False
1 False True False
2 False False True
3 False False False
4 False False False
>>> df.isnull().any(axis=1)
0 False
1 True
2 True
3 False
4 False
dtype: bool
>>> df[df.isnull().any(axis=1)]
0 1 2
1 0 NaN 0
2 0 0 NaN
[For older pandas
:]
You could use the function isnull
instead of the method:
In [56]: df = pd.DataFrame([range(3), [0, np.NaN, 0], [0, 0, np.NaN], range(3), range(3)])
In [57]: df
Out[57]:
0 1 2
0 0 1 2
1 0 NaN 0
2 0 0 NaN
3 0 1 2
4 0 1 2
In [58]: pd.isnull(df)
Out[58]:
0 1 2
0 False False False
1 False True False
2 False False True
3 False False False
4 False False False
In [59]: pd.isnull(df).any(axis=1)
Out[59]:
0 False
1 True
2 True
3 False
4 False
leading to the rather compact:
In [60]: df[pd.isnull(df).any(axis=1)]
Out[60]:
0 1 2
1 0 NaN 0
2 0 0 NaN
If you have created a tag called release01
in a Git repository you would remove it from your repository by doing the following:
git tag -d release01
git push origin :refs/tags/release01
To remove one from a Mercurial repository:
hg tag --remove featurefoo
Please reference https://confluence.atlassian.com/pages/viewpage.action?pageId=282175551
I can't get it to work on $.get()
because it has no complete
event.
I suggest to use $.ajax()
like this,
$.ajax({
url: 'http://www.example.org',
data: {'a':1,'b':2,'c':3},
dataType: 'xml',
complete : function(){
alert(this.url)
},
success: function(xml){
}
});
Sets behave different than dicts, you need to use set operations like issubset():
>>> k
{'ip': '123.123.123.123', 'pw': 'test1234', 'port': 1234, 'debug': True}
>>> set('ip,port,pw'.split(',')).issubset(set(k.keys()))
True
>>> set('ip,port,pw'.split(',')) in set(k.keys())
False
My issue was that I called nltk.download('all')
as the root user, but the process that eventually used nltk was another user who didn't have access to /root/nltk_data where the content was downloaded.
So I simply recursively copied everything from the download location to one of the paths where NLTK was looking to find it like this:
cp -R /root/nltk_data/ /home/ubuntu/nltk_data
While this question was asked a while ago and I don't know the state of the libraries at that point, it is worth mentioning for searchers that GitPython does a good job of abstracting the command line tools so that you don't need to use subprocess. There are some useful built in abstractions that you can use, but for everything else you can do things like:
import git
repo = git.Repo( '/home/me/repodir' )
print repo.git.status()
# checkout and track a remote branch
print repo.git.checkout( 'origin/somebranch', b='somebranch' )
# add a file
print repo.git.add( 'somefile' )
# commit
print repo.git.commit( m='my commit message' )
# now we are one commit ahead
print repo.git.status()
Everything else in GitPython just makes it easier to navigate. I'm fairly well satisfied with this library and appreciate that it is a wrapper on the underlying git tools.
UPDATE: I've switched to using the sh module for not just git but most commandline utilities I need in python. To replicate the above I would do this instead:
import sh
git = sh.git.bake(_cwd='/home/me/repodir')
print git.status()
# checkout and track a remote branch
print git.checkout('-b', 'somebranch')
# add a file
print git.add('somefile')
# commit
print git.commit(m='my commit message')
# now we are one commit ahead
print git.status()
Rather give names of the column on which you want to merge:
exporttab <- merge(x=dwd_nogap, y=dwd_gap, by.x='x1', by.y='x2', fill=-9999)
You must use the following:
NSCalendar *gregorian = [[NSCalendar alloc] initWithCalendarIdentifier:NSGregorianCalendar];
NSDateComponents *dateComponents = [gregorian components:(NSHourCalendarUnit | NSMinuteCalendarUnit | NSSecondCalendarUnit) fromDate:yourDateHere];
NSInteger hour = [dateComponents hour];
NSInteger minute = [dateComponents minute];
NSInteger second = [dateComponents second];
[gregorian release];
There is no difference between NSDate* now and NSDate *now, it's just a matter of preference. From the compiler perspective, nothing changes.
I had the exact same problem with version 7.0.0.0, and the lib causing my problem was Microsoft.Rest.ClientRuntime which somehow was referring to the wrong version (6.0.0.0) of Newtonsoft.json, despite the right dependency management in nugget (the right version of newtonsoft.json (7.0.0.0) was installed).
I solved this by applying the redirection above from 6.0.0.0 to 7.0.0.0 (from Kadir Can) in the config file:
<bindingRedirect oldVersion="0.0.0.0-6.0.0.0" newVersion="7.0.0.0" />
----> After a few days without changing anything it came up again with the same error. I installed version 6.0.0.0 n updated it to 7.0.0.0 it works fine now.
I'm using VS2013 for Winforms, the below solution worked for me.
Download : http://www.microsoft.com/en-us/download/details.aspx?displaylang=en&id=23734
Then Set VS Target Platform to x86.
I've found a workaround for this.
NuGet will restore only the packages used in your solution. You end up with a nice, streamlined set of packages.
I too struggled with something similar. My guess is your actual problem is connecting to a SQL Express instance running on a different machine. The steps to do this can be summarized as follows:
At this point you should be able to connect remotely, using SQL Authentication, user "sqlUser" password "sql" to the SQL Express instance configured as above. A final tip and easy way to check this out is to create an empty text file with the .UDL extension, say "Test.UDL" on your desktop. Double-clicking to edit this file invokes the Microsoft Data Link Properties dialog with which you can quickly test your remote SQL connection
In addition to existing answers:
RUN apt-get update && apt-get install -y gnupg
-y flag agrees to terms during installation process. It is important not to break the build
webElement = driver.findElement(By.xpath("bla-bla-bla"));
((JavascriptExecutor)driver).executeScript("arguments[0].scrollIntoView();", webElement);
For more examples, go here. All in Russian, but Java code is cross-cultural :)
The answers and the documentation provided by MSDN is the best, but I would like to add one typical case that I use a lot which requires the use of #pragma comment
to send a command to the linker at link time for example
#pragma comment(linker,"/ENTRY:Entry")
tell the linker to change the entry point form WinMain()
to Entry()
after that the CRTStartup
going to transfer controll to Entry()

http://docs.oracle.com/javase/1.5.0/docs/api/java/util/Scanner.html
Thus scan.close()
closes System.in
.
To fix it you can make
Scanner scan
static
and do not close it in PromptCustomerQty. Code below works.
public static void main (String[] args) {
// Create a customer
// Future proofing the possabiltiies of multiple customers
Customer customer = new Customer("Will");
// Create object for each Product
// (Name,Code,Description,Price)
// Initalize Qty at 0
Product Computer = new Product("Computer","PC1003","Basic Computer",399.99);
Product Monitor = new Product("Monitor","MN1003","LCD Monitor",99.99);
Product Printer = new Product("Printer","PR1003x","Inkjet Printer",54.23);
// Define internal variables
// ## DONT CHANGE
ArrayList<Product> ProductList = new ArrayList<Product>(); // List to store Products
String formatString = "%-15s %-10s %-20s %-10s %-10s %n"; // Default format for output
// Add objects to list
ProductList.add(Computer);
ProductList.add(Monitor);
ProductList.add(Printer);
// Ask users for quantities
PromptCustomerQty(customer, ProductList);
// Ask user for payment method
PromptCustomerPayment(customer);
// Create the header
PrintHeader(customer, formatString);
// Create Body
PrintBody(ProductList, formatString);
}
static Scanner scan;
public static void PromptCustomerQty(Customer customer, ArrayList<Product> ProductList) {
// Initiate a Scanner
scan = new Scanner(System.in);
// **** VARIABLES ****
int qty = 0;
// Greet Customer
System.out.println("Hello " + customer.getName());
// Loop through each item and ask for qty desired
for (Product p : ProductList) {
do {
// Ask user for qty
System.out.println("How many would you like for product: " + p.name);
System.out.print("> ");
// Get input and set qty for the object
qty = scan.nextInt();
}
while (qty < 0); // Validation
p.setQty(qty); // Set qty for object
qty = 0; // Reset count
}
// Cleanup
}
public static void PromptCustomerPayment (Customer customer) {
// Variables
String payment = "";
// Prompt User
do {
System.out.println("Would you like to pay in full? [Yes/No]");
System.out.print("> ");
payment = scan.next();
} while ((!payment.toLowerCase().equals("yes")) && (!payment.toLowerCase().equals("no")));
// Check/set result
if (payment.toLowerCase() == "yes") {
customer.setPaidInFull(true);
}
else {
customer.setPaidInFull(false);
}
}
On a side note, you shouldn't use ==
for String comparision, use .equals
instead.
I recently created tuna for visualizing Python runtime and import profiles; this may be helpful here.
Install with
pip install tuna
Create a runtime profile
python3 -m cProfile -o program.prof yourfile.py
or an import profile (Python 3.7+ required)
python3 -X importprofile yourfile.py 2> import.log
Then just run tuna on the file
tuna program.prof
Node.js
itself offers an HTTP module, whose createServer method returns an object that you can use to respond to HTTP requests. That object inherits the http.Server
prototype.
The reason you are getting the the IOException is because you are not catching the IOException of your countLines method. You'll want to do something like this:
public static void main(String[] args) {
int lines = 0;
// TODO - Need to get the filename to populate sFileName. Could
// come from the command line arguments.
try {
lines = LineCounter.countLines(sFileName);
}
catch(IOException ex){
System.out.println (ex.toString());
System.out.println("Could not find file " + sFileName);
}
if(lines > 0) {
// Do rest of program.
}
}
It can be better if you set the a element in this way
display:block;
and then by css sprites set your over background
Edit: check this example out http://jsfiddle.net/steweb/dTwtk/
I had a similar problem, and it was because one of my beans had been moved to another directory recently. I needed to do a "build clean" by deleting the build/classes/java
directory and the problem went away. (The error message had the two different file paths conflicting with each other, although I knew one should not actually exist anymore.)
Try from your code socket.socket.sessionid ie.
var socket = io.connect('http://localhost');
alert(socket.socket.sessionid);
var sendBtn= document.getElementById('btnSend');
sendBtn.onclick= function(){
var userId=document.getElementById('txt1').value;
var userMsg = document.getElementById('txt2').value;
socket.emit('sendto',{username: userId, message: userMsg});
};
socket.on('news', function (data) {
console.log(data);
socket.emit('my other event', { my: 'data' });
});
socket.on('message',function(data){ console.log(data);});
There is no need to use any tool !! We can follow the simple way.
I do not know which tool built your self-extracting Setup program and so, I will have to provide a general response.
Most programs of this nature extract the package file (.msi) into the TEMP directory. This behavior is the default behavior of InstallShield Developer.
Without additional information, I would recommend that you simply launch the setup and once the first MSI dialog is displayed, you can examine your TEMP directory for a newly created sub-directory or MSI file. Before cancelling/stopping an installer just copy that MSI file from TEMP folder. After that you can cancel the installation.
I found the answer here:
https://web.archive.org/web/20160421163524/http://vijayt.com/Post/Set-RadioButton-value-using-jQuery
Basically, if you want to check one radio button, you MUST pass the value as an array:
$('input:radio[name=cols]').val(['Site']);
$('input:radio[name=rows]').val(['Site']);
I resolved this by adding a new source folder and putting my java file inside that folder. "source folder" is not just any folder i believe. its some special folder type for java/eclipse and can be added in eclipse by right-click on project -> properties -> Java buld path -> Source and add a folder
In case you want to see the local variables of a calling function use select-frame
before info locals
E.g.:
(gdb) bt
#0 0xfec3c0b5 in _lwp_kill () from /lib/libc.so.1
#1 0xfec36f39 in thr_kill () from /lib/libc.so.1
#2 0xfebe3603 in raise () from /lib/libc.so.1
#3 0xfebc2961 in abort () from /lib/libc.so.1
#4 0xfebc2bef in _assert_c99 () from /lib/libc.so.1
#5 0x08053260 in main (argc=1, argv=0x8047958) at ber.c:480
(gdb) info locals
No symbol table info available.
(gdb) select-frame 5
(gdb) info locals
i = 28
(gdb)
(T)Activator.CreateInstance(typeof(T), param1, param2);
Using name on a select option is not valid.
Other have suggested the data- attribute, an alternative is a lookup table
Here the "this" refers to the select so no need to "find" the option

I would say that the arguments in favor of omitting the tag look stronger (helps to avoid big headache with header() + it's PHP/Zend "recommendation"). I admit that this isn't the most "beautiful" solution I've ever seen in terms of syntax consistency, but what could be better ?
# docker exec -d container_id command
Ex:
# docker exec -d xcdefrdtt service jira stop
The key point was "HARD TAB" 1. Check whether you used TAB instead of whitespace 2. Check your .vimrc for "set tabstop=X"
You can explicitly export it to the global scope with global.FOO = 5
. Then you simply need to require the file, and not even save your return value.
But really, you shouldn't do that. Keeping things properly encapsulated is a good thing. You have the right idea already, so keep doing what you're doing.
As per this the default is 2 MB for your <Connector>
.
maxPostSize = The maximum size in bytes of the POST which will be handled by the container FORM URL parameter parsing. The limit can be disabled by setting this attribute to a value less than or equal to 0. If not specified, this attribute is set to 2097152 (2 megabytes).
Edit Tomcat's server.xml. In the <Connector>
element, add an attribute maxPostSize
and set a larger value (in bytes) to increase the limit.
Having said that, if this is the issue, you should have got an exception on the lines of
Post data too big
in tomcat
a=[[1,2] , [3,4] , [0,5,4]]
print(a.__contains__([0,5,4]))
It provides true output.
a=[[1,2] , [3,4] , [0,5,4]]
print(a.__contains__([1,3]))
It provides false output.
Got the solution and it's working fine. Set the environment variables as:
CATALINA_HOME=C:\Program Files\Java\apache-tomcat-7.0.59\apache-tomcat-7.0.59
(path where your Apache Tomcat is)JAVA_HOME=C:\Program Files\Java\jdk1.8.0_25;
(path where your JDK is)JRE_Home=C:\Program Files\Java\jre1.8.0_25;
(path where your JRE is)CLASSPATH=%JAVA_HOME%\bin;%JRE_HOME%\bin;%CATALINA_HOME%\lib
From my experience, you don't need to do anything particular about file fields, you just tell it to make use of the file field:
from rest_framework import routers, serializers, viewsets
class Photo(django.db.models.Model):
file = django.db.models.ImageField()
def __str__(self):
return self.file.name
class PhotoSerializer(serializers.ModelSerializer):
class Meta:
model = models.Photo
fields = ('id', 'file') # <-- HERE
class PhotoViewSet(viewsets.ModelViewSet):
queryset = models.Photo.objects.all()
serializer_class = PhotoSerializer
router = routers.DefaultRouter()
router.register(r'photos', PhotoViewSet)
api_urlpatterns = ([
url('', include(router.urls)),
], 'api')
urlpatterns += [
url(r'^api/', include(api_urlpatterns)),
]
and you're ready to upload files:
curl -sS http://example.com/api/photos/ -F 'file=@/path/to/file'
Add -F field=value
for each extra field your model has. And don't forget to add authentication.
If strMyString.Contains("Something") or strMyString.Contains("Something2") Then
End if
The error indicates that the compiler thinks you want to do a bitwise OR
on a Boolean and a string. Which of course won't work.
I also faced a similar issue, in my case I had to set titles dynamically on each activity depending on the content.
So this worked for me.
actionBar.setTitle(" " + yourActivityTitle);
If all you want is the spacing, this is the easiest solution I could think of.
For example, say you were creating a web application to list and display recipes. You might want your customers to be able to sort the list, display features of the recipes, and so on before they choose the recipe to open. In order to do this, you need to associate things like cooking time, primary ingredient, meal position, and so on right inside the list elements for the recipes.
<li><a href="recipe1.html">Borscht</a></li>
<li><a href="recipe2.html">Chocolate Mousse</a></li>
<li><a href="recipe3.html">Almond Radiccio Salad</a></li>
<li><a href="recipe4.html">Deviled Eggs</a></li>
In order to get that information into the page, you could do many different things. You could add comments to each LI element, you could add rel attributes to the list items, you could place all the recipes in separate folders based on time, meal, and ingredient (i.e. ). The solution that most developers took was to use class attributes to store information about the current element. This has several advantages:
But there are some major drawbacks to this method:
All the other methods I suggested had these problems as well as others. But since it was the only way to quickly and easily include data, that’s what we did. HTML5 Data Attributes to the Rescue
HTML5 added a new type of attribute to any element—the custom data element (data-*). These are custom (denoted by the *) attributes that you can add to your HTML elements to define any type of data you want. They consist of two parts:
Attribute Name This is the name of the attribute. It must be at least one lowercase character and have the prefix data-. For example: data-main-ingredient, data-cooking-time, data-meal. This is the name of your data.
Attribute Vaule Like any other HTML attribute, you include the data itself in quotes separated by an equal sign. This data can be any string that is valid on a web page. For example: data-main-ingredient="chocolate".
You can then apply these data attributes to any HTML element you want. For example, you could define the information in the example list above:
<li data-main-ingredient="beets" data-cooking-time="1 hour" data-meal="dinner"><a href="recipe1.html">Borscht</a></li>
<li data-main-ingredient="chocolate" data-cooking-time="30 minutes" data-meal="dessert"><a href="recipe2.html">Chocolate Mousse</a></li>
<li data-main-ingredient="radiccio" data-cooking-time="20 minutes" data-meal="dinner"><a href="recipe1.html">Almond Radiccio Salad</a></li>
<li data-main-ingredient="eggs" data-cooking-time="15 minutes" data-meal="appetizer"><a href="recipe1.html">Deviled Eggs</a></li>
Once you have that information in your HTML, you will be able to access it with JavaScript and manipulate the page based on that data.
This is quite difficult to do with pure regex because URLs have many 'inconveniences'.
For example domain names have complicated restrictions on hyphens:
a. It is allowed to have many consecutive hyphens in the middle.
b. but the first character and last character of the domain name cannot be a hyphen
c. The 3rd and 4th character cannot be both hyphen
Similarly port number can only be in the range 1-65535. This is easy to check if you extract the port part and convert to int
but quite difficult to check with a regular expression.
There is also no easy way to check valid domain extensions. Some countries have second-level domains(such as 'co.uk'), or the extension can be a long word such as '.international'. And new TLDs are added regularly. This type of things can only be checked against a hard-coded list. (see https://en.wikipedia.org/wiki/Top-level_domain)
Then there are magnet urls, ftp addresses etc. These all have different requirements.
Nevertheless, here is a function that handles pretty much everything except:

There are only 4 kinds:
NULL
for each value in the table on the right. This means that every row from the table on the left will appear at least once in the output. A "cross join" or "cartesian join" is simply an inner join for which no join conditions have been specified, resulting in all pairs of rows being output.
Thanks to RusselH for pointing out FULL joins, which I'd omitted.

You can remove unwanted commits with git rebase
.
Say you included some commits from a coworker's topic branch into your topic branch, but later decide you don't want those commits.
git checkout -b tmp-branch my-topic-branch # Use a temporary branch to be safe.
git rebase -i master # Interactively rebase against master branch.
At this point your text editor will open the interactive rebase view. For example
If the rebase wasn't successful, delete the temporary branch and try another strategy. Otherwise continue with the following instructions.
git checkout my-topic-branch
git reset --hard tmp-branch # Overwrite your topic branch with the temp branch.
git branch -d tmp-branch # Delete the temporary branch.
If you're pushing your topic branch to a remote, you may need to force push since the commit history has changed. If others are working on the same branch, give them a heads up.
When you install anaconda on windows now, it doesn't automatically add Python or Conda to your path.
While during the installation process you can check this box, you can also add python and/or python to your path manually (as you can see below the image)
If you don’t know where your conda and/or python is, you type the following commands into your anaconda prompt
where python
where conda
Next, you can add Python and Conda to your path by using the setx command in your command prompt (replace C:\Users\mgalarnyk\Anaconda2
with the results you got when running where python
and where conda
).
SETX PATH "%PATH%;C:\Users\mgalarnyk\Anaconda2\Scripts;C:\Users\mgalarnyk\Anaconda2"
Next close that command prompt and open a new one. Congrats you can now use conda and python

Short answer:
There is no difference in semantic.
Specifically, @GetMapping is a composed annotation that acts as a shortcut for @RequestMapping(method = RequestMethod.GET).
Further reading:
RequestMapping
can be used at class level:
This annotation can be used both at the class and at the method level. In most cases, at the method level applications will prefer to use one of the HTTP method specific variants @GetMapping, @PostMapping, @PutMapping, @DeleteMapping, or @PatchMapping.
while GetMapping
only applies to method:
Annotation for mapping HTTP GET requests onto specific handler methods.
You can try something like this:
List<Book> books = new ArrayList<Book>();
Collections.sort(books, new Comparator<Book>(){
public int compare(Book o1, Book o2)
{
return o1.name.compareTo(o2.name);
}
});
If you set the implicit wait of the driver, then call the findElement
method on an element you expect to be on the loaded page, the WebDriver will poll for that element until it finds the element or reaches the time out value.
driver.manage().timeouts().implicitlyWait(10, TimeUnit.SECONDS);

There are a many ways to create your objects in JavaScript. Using a constructer function to create an object or object literal notation is using alot in JavaScript. Also creating an instance of Object and then adding properties and methods to it, there are three common ways to do create objects in JavaScript.
Constructer functions
There are built-in constructer functions that we all may use them time to time, like Date(), Number(), Boolean() etc, all constructer functions start with Capital letter, in the meantime we can create custom constructor function in JavaScript like this:
function Box (Width, Height, fill) {
this.width = Width; // The width of the box
this.height = Height; // The height of the box
this.fill = true; // Is it filled or not?
}
and you can invoke it, simply using new(), to create a new instance of the constructor, create something like below and call the constructor function with filled parameters:
var newBox = new Box(8, 12, true);
Object literals
Using object literals are very used case creating object in JavaScript, this an example of creating a simple object, you can assign anything to your object properties as long as they are defined:
var person = {
name: "Alireza",
surname: "Dezfoolian"
nose: 1,
feet: 2,
hands: 2,
cash: null
};
Prototyping
After creating an Object, you can prototype more members to that, for example adding colour to our Box, we can do this:
Box.prototype.colour = 'red';
A bit late to the party but I decided to create my own one after looking at @Alex Macmillan answers and that was by passing two extra parameters; the position in which to place the scripts such as or and setting up the async to true/false, here it is:
import { useEffect } from 'react';
const useScript = (url, position, async) => {
useEffect(() => {
const placement = document.querySelector(position);
const script = document.createElement('script');
script.src = url;
script.async = typeof async === 'undefined' ? true : async;
placement.appendChild(script);
return () => {
placement.removeChild(script);
};
}, [url]);
};
export default useScript;
The way to call it is exactly the same as shown in the accepted answer of this post but with two extra(again) parameters:
// First string is your URL
// Second string can be head or body
// Third parameter is true or false.

From there, use vim for everything. "hjkl", "y", and "p" will get you a long way, even if it's not the most efficient way. When you come up against a task for which you don't know the magic key to do it efficiently (or at all), and you find yourself doing it more than a few times, go look it up. Little by little it will become second nature.
I found vim daunting many moons ago (back when it didn't have the "m" on the end), but it only took about a week of steady use to get efficient. I still find it the quickest editor in which to get stuff done.
You have a string representing a JSON serialized JavaScript object. You need to deserialize it back to a JavaScript object before being able to loop through its properties. Otherwise you will be looping through each individual character of this string.
var resultJSON = '{"FirstName":"John","LastName":"Doe","Email":"[email protected]","Phone":"123 dead drive"}';
var result = $.parseJSON(resultJSON);
$.each(result, function(k, v) {
//display the key and value pair
alert(k + ' is ' + v);
});
In asp.net for giving new line character in string you should use <br>
.
For window base application Environment.NewLine
will work fine.
It worked for me:
General -> Encryption -> Only use plain FTP
Transfer settings -> Transfer Mode -> Active
Consider that it is very insecure, and must be used only for testing.
I solved this with this commands:
1- Run the container
# docker run -d <image-name>
2- List containers
# docker ps -a
3- Use the container ID
# docker exec -it <container-id> /bin/sh
The excellent book "Algorithm Design Manual" by Skienna contains a huge repository of Algorithms and Data structure.
For tons of problems, data structures and algorithm are described, compared, and discusses the practical usage. The author also provides references to implementations and the original research papers.
The book is great to have it on your desk if you search the best data structure for your problem to solve. It is also very helpful for interview preparation.
Another great resource is the NIST Dictionary of Data structures and algorithms.
Try this:
retVal = Shell("python.exe <full path to your python script>", vbNormalFocus)
replace <full path to your python script>
with the full path
I believe this is what you're looking for:
Convert Decimal Numbers to Text showing only the non-zero decimals
Especially this line might be helpful:
StringVar text := Totext ( {Your.NumberField} , 6 , "" ) ;
The first parameter is the decimal to be converted, the second parameter is the number of decimal places and the third parameter is the separator for thousands/millions etc.
This is my first crack at a query, based on Andomar's suggestions. This query is intended to provide a list of permissions that a user has either applied directly to the user account, or through roles that the user has.
/*
Security Audit Report
1) List all access provisioned to a sql user or windows user/group directly
2) List all access provisioned to a sql user or windows user/group through a database or application role
3) List all access provisioned to the public role
Columns Returned:
UserName : SQL or Windows/Active Directory user account. This could also be an Active Directory group.
UserType : Value will be either 'SQL User' or 'Windows User'. This reflects the type of user defined for the
SQL Server user account.
DatabaseUserName: Name of the associated user as defined in the database user account. The database user may not be the
same as the server user.
Role : The role name. This will be null if the associated permissions to the object are defined at directly
on the user account, otherwise this will be the name of the role that the user is a member of.
PermissionType : Type of permissions the user/role has on an object. Examples could include CONNECT, EXECUTE, SELECT
DELETE, INSERT, ALTER, CONTROL, TAKE OWNERSHIP, VIEW DEFINITION, etc.
This value may not be populated for all roles. Some built in roles have implicit permission
definitions.
PermissionState : Reflects the state of the permission type, examples could include GRANT, DENY, etc.
This value may not be populated for all roles. Some built in roles have implicit permission
definitions.
ObjectType : Type of object the user/role is assigned permissions on. Examples could include USER_TABLE,
SQL_SCALAR_FUNCTION, SQL_INLINE_TABLE_VALUED_FUNCTION, SQL_STORED_PROCEDURE, VIEW, etc.
This value may not be populated for all roles. Some built in roles have implicit permission
definitions.
ObjectName : Name of the object that the user/role is assigned permissions on.
This value may not be populated for all roles. Some built in roles have implicit permission
definitions.
ColumnName : Name of the column of the object that the user/role is assigned permissions on. This value
is only populated if the object is a table, view or a table value function.

HTML doesn't have a built-in editable dropdown list or combobox, but I implemented a mostly-CSS solution in an article.
You can see a full demo here but in summary, write HTML like this:
<span class="combobox withtextlist">
<input value="Fruit">
<span tabindex="-1" class="downarrow"></span>
<select size="10" class="sticky">
<option>Apple</option>
<option>Banana</option>
<option>Cherry</option>
<option>Dewberry</option>
</select>
</span>
And use CSS like this to style it (this is designed for both comboboxes, which have a down-arrow ? button, and dropdown menus which open when clicked and may be styled differently):
/* ------------------------------------------ */
/* ----- combobox / dropdown list styling */
/* ------------------------------------------ */
.combobox {
/* Border slightly darker than Chrome's <select>, slightly lighter than FireFox's */
border: 1px solid #999;
padding-right: 1.25em; /* leave room for ? */
}
.dropdown, .combobox {
/* "relative" and "inline-block" (or just "block") are needed
here so that "absolute" works correctly in children */
position: relative;
display: inline-block;
}
.combobox > .downarrow, .dropdown > .downarrow {
/* ? Outside normal flow, relative to container */

(1) Accessibility: it lets input widgets in the dropdown to

(2) It lets the opacity transition work.
But it also makes the contents visible, which is undesirable
before the list drops down. To compensate, use `opacity: 0`
and disable mouse pointer events. Another side effect is that
the user can select and copy the contents of the hidden list,
but don't worry, the selected content is invisible. */

You also need some JavaScript to synchronize the list with the textbox:
function parentComboBox(el) {
for (el = el.parentNode; el != null && Array.prototype.indexOf.call(el.classList, "combobox") <= -1;)
el = el.parentNode;
return el;
}
// Uses jQuery
$(".combobox.withtextlist > select").change(function() {
var textbox = parentComboBox(this).firstElementChild;
textbox.value = this[this.selectedIndex].text;
});
$(".combobox.withtextlist > select").keypress(function(e) {
if (e.keyCode == 13) // Enter pressed
parentComboBox(this).firstElementChild.focus(); // Closes the popup
});
A connection timeout is the maximum amount of time that the program is willing to wait to setup a connection to another process. You aren't getting or posting any application data at this point, just establishing the connection, itself.
A socket timeout is the timeout when waiting for individual packets. It's a common misconception that a socket timeout is the timeout to receive the full response. So if you have a socket timeout of 1 second, and a response comprised of 3 IP packets, where each response packet takes 0.9 seconds to arrive, for a total response time of 2.7 seconds, then there will be no timeout.
In this instance, your div
elements have been changed from block
level elements to inline
elements. A typical characteristic of inline
elements is that they respect the whitespace in the markup. This explains why a gap of space is generated between the elements. (example)
There are a few solutions that can be used to solve this.
Example 1 - Comment the whitespace out: (example)
<div>text</div><!--
--><div>text</div><!--
--><div>text</div><!--
--><div>text</div><!--
--><div>text</div>
Example 2 - Remove the line breaks: (example)
<div>text</div><div>text</div><div>text</div><div>text</div><div>text</div>
Example 3 - Close part of the tag on the next line (example)
<div>text</div
><div>text</div
><div>text</div
><div>text</div
><div>text</div>
Example 4 - Close the entire tag on the next line: (example)
<div>text
</div><div>text
</div><div>text
</div><div>text
</div><div>text
</div>
font-size
Since the whitespace between the inline
elements is determined by the font-size
, you could simply reset the font-size
to 0
, and thus remove the space between the elements.
Just set font-size: 0
on the parent elements, and then declare a new font-size
for the children elements. This works, as demonstrated here (example)
#parent {
font-size: 0;
}
#child {
font-size: 16px;
}
This method works pretty well, as it doesn't require a change in the markup; however, it doesn't work if the child element's font-size
is declared using em
units. I would therefore recommend removing the whitespace from the markup, or alternatively floating the elements and thus avoiding the space generated by inline
elements.
display: flex
In some cases, you can also set the display
of the parent element to flex
. (example)
This effectively removes the spaces between the elements in supported browsers. Don't forget to add appropriate vendor prefixes for additional support.
.parent {
display: flex;
}
.parent > div {
display: inline-block;
padding: 1em;
border: 2px solid #f00;
}
.parent {_x000D_
display: flex;_x000D_
}_x000D_
.parent > div {_x000D_
display: inline-block;_x000D_
padding: 1em;_x000D_
border: 2px solid #f00;_x000D_
}
_x000D_
<div class="parent">_x000D_
<div>text</div>_x000D_
<div>text</div>_x000D_
<div>text</div>_x000D_
<div>text</div>_x000D_
<div>text</div>_x000D_
</div>
_x000D_
It is incredibly unreliable to use negative margins to remove the space between inline
elements. Please don't use negative margins if there are other, more optimal, solutions.
Constructor is special function used to initialise the data member, where the methods are functions to perform specific task.
Constructor name is the same name as the class name, where the method name may or may not or be class name.
Constructor does not allow any return type, where methods allow return type.
for just debugging purpose, use one line code -
msg.writeTo(System.out);
you can simply prevent adding non-numerical chars by this simple code
if (long.TryParse(TextBox.Text,out long isparsable))
{
// your code to handle numbers
}
else
{
TextBox.Text="Only Numbers Allowed";
TextBox.Focus();
TextBox.SelectAll();
}
you can use the context of the view that did the calling. Example:
Button orderButton = (Button)findViewById(R.id.order);
orderButton.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
Intent intent = new Intent(/*FirstActivity.this*/ view.getContext(), OrderScreen.class);
startActivity(intent);
}
});
R doesn't have a concept of increment operator
(as for example ++ in C). However, it is not difficult to implement one yourself, for example:
inc <- function(x)
{
eval.parent(substitute(x <- x + 1))
}
In that case you would call
x <- 10
inc(x)
However, it introduces function call overhead, so it's slower than typing x <- x + 1
yourself. If I'm not mistaken increment operator
was introduced to make job for compiler easier, as it could convert the code to those machine language instructions directly.
What even is ‘children’?
The React docs say that you can use
props.children
on components that represent ‘generic boxes’ and that don’t know their children ahead of time. For me, that didn’t really clear things up. I’m sure for some, that definition makes perfect sense but it didn’t for me.My simple explanation of what
this.props.children
does is that it is used to display whatever you include between the opening and closing tags when invoking a component.A simple example:
Here’s an example of a stateless function that is used to create a component. Again, since this is a function, there is no
this
keyword so just useprops.children
const Picture = (props) => {
return (
<div>
<img src={props.src}/>
{props.children}
</div>
)
}
This component contains an
<img>
that is receiving someprops
and then it is displaying{props.children}
.Whenever this component is invoked
{props.children}
will also be displayed and this is just a reference to what is between the opening and closing tags of the component.
//App.js
render () {
return (
<div className='container'>
<Picture key={picture.id} src={picture.src}>
//what is placed here is passed as props.children
</Picture>
</div>
)
}
Instead of invoking the component with a self-closing tag
<Picture />
if you invoke it will full opening and closing tags<Picture> </Picture>
you can then place more code between it.This de-couples the
<Picture>
component from its content and makes it more reusable.
Reference: A quick intro to React’s props.children
Very simple solution. Just rename your database and configure your new database name in your project.
The problem is the when you import your database, you got any errors and then the database will be corrupted. The log files will have the corrupted database name. You can rename your database easily using phpmyadmin for mysql.

It has been fun reading the answers to this question. Once you've achieved the 'wow' factor from the students, illustrate the daisy-chaining affect of the results of one becoming the input of another. Learning how input and output works will illustrate the idea of building blocks and how software grows from lots of little things solving specific problems to larger applications solving bigger problems. If a few 10 line programs can be cool, how cool would it be to then put a bunch of them together? That is non-linear cool.
There are some more actions you should consider:
Remove Registry Entries for MS Distributed Transaction Coordinator (MSDTC)
Note: on the Internet I found this step only at a single (private) page. I don't know if it is required/working or if it breaks anything on your PC.
HKEY_LOCAL_MACHINE\Software\Microsoft\MSDTC\MTxOCI
OracleOciLib
, OracleSqlLib
, and OracleXaLib
HKEY_LOCAL_MACHINE\Software\Wow6432Node\Microsoft\MSDTC\MTxOCI
OracleOciLib
, OracleSqlLib
, and OracleXaLib
Otherwise these files, if they exist, will still be in use next time you reboot, and unable to be deleted.
Remove environment variable ORACLE_HOME
, ORACLE_BASE
, TNS_ADMIN
, NLS_LANG
if exist
Check also Oracle doc to find all Oracle related environment variables, however apart from variables listed above they are very rarely used on Windows Client: Oracle Environment Variables
Unregister oci.dll
Enter regsvr32 /u oci.dll
, resp. %windir%\SysWOW64\regsvr32 /u oci.dll
In some cases the file %ORACLE_HOME%\bin\oci.dll
is locked and you cannot delete it. In such case rename the file (e.g. to oci.dll.x) and reboot the PC, afterwards you can delete it.
Remove Oracle .NET assemblies from Global Assembly Cache (GAC). You do this typically with the gacutil utility, if available on your system. Would be like this:
gacutil /u Policy.10.1.Oracle.DataAccess
gacutil /u Policy.10.2.Oracle.DataAccess
gacutil /u Policy.1.102.Oracle.DataAccess
gacutil /u Policy.1.111.Oracle.DataAccess

you can also use OraProvCfg /action:ungac /providerpath:...
if OraProvCfg is still available on your system. You may find it at %ORACLE_HOME%\odp.net\managed\x64\OraProvCfg.exe
.
With a text editor, open XML Config file %SYSTEMROOT%\Microsoft.NET\Framework64\v4.0.30319\Config\machine.config
and delete branch <oracle.manageddataaccess.client>
, if existing.
Do the same with:
%SYSTEMROOT%\Microsoft.NET\Framework64\v4.0.30319\Config\machine.config
%SYSTEMROOT%\Microsoft.NET\Framework\v4.0.30319\Config\machine.config
%SYSTEMROOT%\Microsoft.NET\Framework64\v4.0.30319\Config\web.config
%SYSTEMROOT%\Microsoft.NET\Framework\v4.0.30319\Config\web.config
Instead of editing the XML Config file manually you can also run (if OraProvCfg.exe is still available on your system):
%ORACLE_HOME%\odp.net\managed\x64\OraProvCfg.exe /action:unconfig /product:odpm /frameworkversion:v4.0.30319
%ORACLE_HOME%\odp.net\managed\x86\OraProvCfg.exe /action:unconfig /product:odpm /frameworkversion:v4.0.30319

This error "Unsupported major.minor version 52.0" refers to the java compiler, although the string "major.minor" looks very similar to the Android SDK version format.

For Swift 3.X Latest Working Code, Easily usage;
let deviceID = UIDevice.current.identifierForVendor!.uuidString
print(deviceID)
Converting is simple:
let float = Float(1.1) // 1.1
let int = Int(float) // 1
But it is not safe:
let float = Float(Int.max) + 1
let int = Int(float)
Will due to a nice crash:
fatal error: floating point value can not be converted to Int because it is greater than Int.max
So I've created an extension that handles overflow:
extension Double {
// If you don't want your code crash on each overflow, use this function that operates on optionals
// E.g.: Int(Double(Int.max) + 1) will crash:
// fatal error: floating point value can not be converted to Int because it is greater than Int.max
func toInt() -> Int? {
if self > Double(Int.min) && self < Double(Int.max) {
return Int(self)
} else {
return nil
}
}
}
extension Float {
func toInt() -> Int? {
if self > Float(Int.min) && self < Float(Int.max) {
return Int(self)
} else {
return nil
}
}
}
I hope this can help someone

In your app's basic settings (https://developers.facebook.com/apps) under Settings->Basic->Select how your app integrates with Facebook...
Use "Site URL:" and "Mobile Site URL:" to hold your production and development URLs. Both sites will be allowed to authenticate. I'm just using Facebook for authentication so I don't need any of the mobile site redirection features. I usually change the "Mobile Site URL:" to my "localhost:12345" site while I'm testing the authentication, and then set it back to normal when I'm done.
When the Resolve Conflicts->Content Menu are disabled, one may be on the Pending files list. We need to select the Conflicted files option from the drop down (top)

I have utilize c# Uri class and it works, well with IP Address, localhost
public static bool CheckURLIsValid(string url)
{
Uri returnURL;
return (Uri.TryCreate(url, UriKind.Absolute, out returnURL)
&& (returnURL.Scheme == Uri.UriSchemeHttp || returnURL.Scheme == Uri.UriSchemeHttps));
}
This one works for me. You can see this code on AccountController -> Register
var user = new JobUser { UserName = model.Email, Email = model.Email };
var result = await UserManager.CreateAsync(user, model.Password);
if (result.Succeeded)
{
//add this to add role to user
await UserManager.AddToRoleAsync(user.Id, "Name of your role");
}
but the role name must exist in your AspNetRoles table.

Use the following method.
self.imageView_VedioContainer
is the container view of your AVPlayer
.
- (void)playMedia:(UITapGestureRecognizer *)tapGesture
{
playerViewController = [[AVPlayerViewController alloc] init];
playerViewController.player = [AVPlayer playerWithURL:[[NSBundle mainBundle]
URLForResource:@"VID"
withExtension:@"3gp"]];
[playerViewController.player play];
playerViewController.showsPlaybackControls =YES;
playerViewController.view.frame=self.imageView_VedioContainer.bounds;
[playerViewController.view setAutoresizingMask:UIViewAutoresizingNone];// you can comment this line
[self.imageView_VedioContainer addSubview: playerViewController.view];
}
Here ya go:
viewNoteDateMonth.text = [[displayDate objectAtIndex:2] uppercaseString];
Btw:
"april"
is lowercase
? [NSString lowercaseString]
"APRIL"
is UPPERCASE
? [NSString uppercaseString]
"April May"
is Capitalized/Word Caps
? [NSString capitalizedString]
"April may"
is Sentence caps
? (method missing; see workaround below)
Hence what you want is called "uppercase", not "capitalized". ;)
As for "Sentence Caps" one has to keep in mind that usually "Sentence" means "entire string". If you wish for real sentences use the second method, below, otherwise the first:
@interface NSString ()
- (NSString *)sentenceCapitalizedString; // sentence == entire string
- (NSString *)realSentenceCapitalizedString; // sentence == real sentences
@end
@implementation NSString
- (NSString *)sentenceCapitalizedString {
if (![self length]) {
return [NSString string];
}
NSString *uppercase = [[self substringToIndex:1] uppercaseString];
NSString *lowercase = [[self substringFromIndex:1] lowercaseString];
return [uppercase stringByAppendingString:lowercase];
}
- (NSString *)realSentenceCapitalizedString {
__block NSMutableString *mutableSelf = [NSMutableString stringWithString:self];
[self enumerateSubstringsInRange:NSMakeRange(0, [self length])
options:NSStringEnumerationBySentences
usingBlock:^(NSString *sentence, NSRange sentenceRange, NSRange enclosingRange, BOOL *stop) {
[mutableSelf replaceCharactersInRange:sentenceRange withString:[sentence sentenceCapitalizedString]];
}];
return [NSString stringWithString:mutableSelf]; // or just return mutableSelf.
}
@end
Talking is more than simply exchanging information. A Protocol is actually designed so that no talking has to occur. Each party knows what their particular job is because it is specified in the protocol. Protocols allow for pure information exchange at the expense of having any changes in the possible actions. Talking, on the other hand, allows for one party to ask what further actions can be taken from the other party. They can even ask the same question twice and get two different answers, since the State of the other party may have changed in the interim. Talking is RESTful architecture. Fielding's thesis specifies the architecture that one would have to follow if one wanted to allow machines to talk to one another rather than simply communicate.
It sounds like you're looking for applicationHost.config
, which is located in C:\Windows\System32\inetsrv\config
.
Yes, it's an XML file, and yes, editing the file by hand will affect the IIS config after a restart. You can think of IIS Manager as a GUI front-end for editing applicationHost.config
and web.config
.
this error is also caused by null pointer reference. if you are using a pointer who is not initialized then it causes this error.
to check either a pointer is initialized or not you can try something like
Class *pointer = new Class();
if(pointer!=nullptr){
pointer->myFunction();
}

Yes! You can Debug Android Application While you are developing them follow these steps.. Make sure that you have PC suite of the mobile manufacturer. For Example:if you are using samsung you should have samsung kies
1.Enable USB debugging on your device:Settings > Applications > Development > USB debugging
2.Enable Unknownresources:Settings>Unknowresoures
3.Connect your device to PC
4.Select your Application Right click it: RunAS>Run configurations>Choose Device>Target Select your device Run.
You can also without using debugging cable.For that you need to install Airdroid in your device.After installing enter the link in your browser and Drag and Drop .apk file.
Happy Coding!
The size_t type is the type returned by the sizeof operator. It is an unsigned integer capable of expressing the size in bytes of any memory range supported on the host machine. It is (typically) related to ptrdiff_t in that ptrdiff_t is a signed integer value such that sizeof(ptrdiff_t) and sizeof(size_t) are equal.
When writing C code you should always use size_t whenever dealing with memory ranges.
The int type on the other hand is basically defined as the size of the (signed) integer value that the host machine can use to most efficiently perform integer arithmetic. For example, on many older PC type computers the value sizeof(size_t) would be 4 (bytes) but sizeof(int) would be 2 (byte). 16 bit arithmetic was faster than 32 bit arithmetic, though the CPU could handle a (logical) memory space of up to 4 GiB.
Use the int type only when you care about efficiency as its actual precision depends strongly on both compiler options and machine architecture. In particular the C standard specifies the following invariants: sizeof(char) <= sizeof(short) <= sizeof(int) <= sizeof(long) placing no other limitations on the actual representation of the precision available to the programmer for each of these primitive types.
Note: This is NOT the same as in Java (which actually specifies the bit precision for each of the types 'char', 'byte', 'short', 'int' and 'long').
If you declared different variables then use following simple method:
Int salary=2000;
String abc="I Love Pakistan";
Double pi=3.14;
Console.Writeline=salary+"/n"+abc+"/n"+pi;
Console.readkey();
If array is static allocated:
size_t size = sizeof(arr) / sizeof(int);
if array is dynamic allocated(heap):
int *arr = malloc(sizeof(int) * size);
where variable size is a dimension of the arr.
Like thousands of people, I'm looking for this question:
Can run multiple queries simultaneously, and if there was one error, none would run
I went to this page everywhere
But although the friends here gave good answers, these answers were not good for my problem
So I wrote a function that works well and has almost no problem with sql Injection.
It might be helpful for those who are looking for similar questions so I put them here to use
function arrayOfQuerys($arrayQuery)
{
$mx = true;
$conn->beginTransaction();
try {
foreach ($arrayQuery AS $item) {
$stmt = $conn->prepare($item["query"]);
$stmt->execute($item["params"]);
$result = $stmt->rowCount();
if($result == 0)
$mx = false;
}
if($mx == true)
$conn->commit();
else
$conn->rollBack();
} catch (Exception $e) {
$conn->rollBack();
echo "Failed: " . $e->getMessage();
}
return $mx;
}
for use(example):
$arrayQuery = Array(
Array(
"query" => "UPDATE test SET title = ? WHERE test.id = ?",
"params" => Array("aa1", 1)
),
Array(
"query" => "UPDATE test SET title = ? WHERE test.id = ?",
"params" => Array("bb1", 2)
)
);
arrayOfQuerys($arrayQuery);
and my connection:
try {
$options = array(
//For updates where newvalue = oldvalue PDOStatement::rowCount() returns zero. You can use this:
PDO::MYSQL_ATTR_FOUND_ROWS => true
);
$conn = new PDO("mysql:host=$servername;dbname=$database", $username, $password, $options);
$conn->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
} catch (PDOException $e) {
echo "Error connecting to SQL Server: " . $e->getMessage();
}
Note:
This solution helps you to run multiple statement together,
If an incorrect a statement occurs, it does not execute any other statement
One way to solve this problem is to get the starting points from the values themselves:
var minLen, maxLen uint
if len(sliceOfThings) > 0 {
minLen = sliceOfThings[0].minLen
maxLen = sliceOfThings[0].maxLen
for _, thing := range sliceOfThings[1:] {
if minLen > thing.minLen { minLen = thing.minLen }
if maxLen < thing.maxLen { maxLen = thing.maxLen }
}
}
I have written a jquery plugin to solve this problem.. it's free..
JQuery Directory:
In order to make examples from here work with Python 3.5.2, you can rewrite as follows :
import io
data =io.BytesIO(b"1, 2, 3\n4, 5, 6")
import numpy
numpy.genfromtxt(data, delimiter=",")
The reason for the change may be that the content of a file is in data (bytes) which do not make text until being decoded somehow. genfrombytes
may be a better name than genfromtxt
.
I don't know is there any method in Python API.But you can use this simple code to add Salt-and-Pepper noise to an image.
import numpy as np
import random
import cv2
def sp_noise(image,prob):
'''
Add salt and pepper noise to image
prob: Probability of the noise
'''
output = np.zeros(image.shape,np.uint8)
thres = 1 - prob
for i in range(image.shape[0]):
for j in range(image.shape[1]):
rdn = random.random()
if rdn < prob:
output[i][j] = 0
elif rdn > thres:
output[i][j] = 255
else:
output[i][j] = image[i][j]
return output
image = cv2.imread('image.jpg',0) # Only for grayscale image
noise_img = sp_noise(image,0.05)
cv2.imwrite('sp_noise.jpg', noise_img)
Method 1 : Using jQuery Ajax Get call (partial page update).
Suitable for when you need to retrieve jSon data from database.
Controller's Action Method
[HttpGet]
public ActionResult Foo(string id)
{
var person = Something.GetPersonByID(id);
return Json(person, JsonRequestBehavior.AllowGet);
}
Jquery GET
function getPerson(id) {
$.ajax({
url: '@Url.Action("Foo", "SomeController")',
type: 'GET',
dataType: 'json',
// we set cache: false because GET requests are often cached by browsers
// IE is particularly aggressive in that respect
cache: false,
data: { id: id },
success: function(person) {
$('#FirstName').val(person.FirstName);
$('#LastName').val(person.LastName);
}
});
}
Person class
public class Person
{
public string FirstName { get; set; }
public string LastName { get; set; }
}
Method 2 : Using jQuery Ajax Post call (partial page update).
Suitable for when you need to do partial page post data into database.
Post method is also same like above just replace [HttpPost]
on Action method and type as post
for jquery method.
For more information check Posting JSON Data to MVC Controllers Here
Method 3 : As a Form post scenario (full page update).
Suitable for when you need to save or update data into database.
View
@using (Html.BeginForm("SaveData","ControllerName", FormMethod.Post))
{
@Html.TextBoxFor(model => m.Text)
<input type="submit" value="Save" />
}
Action Method
[HttpPost]
public ActionResult SaveData(FormCollection form)
{
// Get movie to update
return View();
}
Method 4 : As a Form Get scenario (full page update).
Suitable for when you need to Get data from database
Get method also same like above just replace [HttpGet]
on Action method and FormMethod.Get
for View's form method.
I hope this will help to you.
git-pull - Fetch from and integrate with another repository or a local branch GIT PULL
Basically you are pulling remote branch to your local, example:
git pull origin master
Will pull master branch into your local repository
git-rebase - Forward-port local commits to the updated upstream head GIT REBASE
This one is putting your local changes on top of changes done remotely by other users. For example:
SOME-FEATURE
Now you want to see his and your changes on your local branch.
So then you checkout master
branch:
git checkout master
then you can pull:
git pull origin master
and then you go to your branch:
git checkout SOME-FEATURE
and you can do rebase master
to get lastest changes from it and put your branch commits on top:
git rebase master
I hope now it's a bit more clear for you.

You can use makefiles in VS, but when you do it bypasses all the built-in functionality in MSVC's IDE. Makefiles are basically the reinterpret_cast of the builder. IMO the simplest thing is just to use Solutions.
If you read JavaScript The Good Parts, you'll see that Crockford's replacement for i++ in a for loop is i+=1 (not i=i+1). That's pretty clean and readable, and is less likely to morph into something "tricky."
Crockford made disallowing autoincrement and autodecrement an option in jsLint. You choose whether to follow the advice or not.
My own personal rule is to not do anything combined with autoincrement or autodecrement.
I've learned from years of experience in C that I don't get buffer overruns (or array index out of bounds) if I keep use of it simple. But I've discovered that I do get buffer overruns if I fall into the "excessively tricky" practice of doing other things in the same statement.
So, for my own rules, the use of i++ as the increment in a for loop is fine.

To check if a string does not contain any whitespaces, you can use
string.matches("^\\S*$")
Example:
"name" -> true
" " -> false
"name xxname" -> false

You can make use of bitwise AND operator &
.
Let's see below:
x = [1, 2, 3, 4, 5, 6, 7]
y = [i for i in x if i&1]
>>>
[1, 3, 5, 7]
Bitwise AND operator is used with 1, and the reason it works because, odd number when written in binary must have its first digit as 1. Let's check
23 = 1 * (2**4) + 0 * (2**3) + 1 * (2**2) + 1 * (2**1) + 1 * (2**0) = 10111
14 = 1 * (2**3) + 1 * (2**2) + 1 * (2**1) + 0 * (2**0) = 1110
AND operation with 1 will only return 1 (1 in binary will also have last digit 1), iff the value is odd.
Check the Python Bitwise Operator page for more.
P.S: You can tactically use this method if you want to select odd and even columns in a dataframe. Let's say x and y coordinates of facial key-points are given as columns x1, y1, x2, etc... To normalize the x and y coordinates with width and height values of each image you can simply perform
for i in range(df.shape[1]):
if i&1:
df.iloc[:, i] /= heights
else:
df.iloc[:, i] /= widths
This is not exactly related to the question but for data scientists and computer vision engineers this method could be useful.
Cheers!
The message from Linus Torvalds may answer your question:
Modify/edit old commit messages
Short answer: you can not (if pushed).
extract (Linus refers to BitKeeper as BK):
Side note, just out of historical interest: in BK you could.
And if you're used to it (like I was) it was really quite practical. I would apply a patch-bomb from Andrew, notice something was wrong, and just edit it before pushing it out.
I could have done the same with git. It would have been easy enough to make just the commit message not be part of the name, and still guarantee that the history was untouched, and allow the "fix up comments later" thing.
But I didn't.
Part of it is purely "internal consistency". Git is simply a cleaner system thanks to everything being SHA1-protected, and all objects being treated the same, regardless of object type. Yeah, there are four different kinds of objects, and they are all really different, and they can't be used in the same way, but at the same time, even if their encoding might be different on disk, conceptually they all work exactly the same.
But internal consistency isn't really an excuse for being inflexible, and clearly it would be very flexible if we could just fix up mistakes after they happen. So that's not a really strong argument.
The real reason git doesn't allow you to change the commit message ends up being very simple: that way, you can trust the messages. If you allowed people to change them afterwards, the messages are inherently not very trustworthy.
To be complete, you could rewrite your local commit history in order to reflect what you want, as suggested by sykora (with some rebase and reset --hard, gasp!)
However, once you publish your revised history again (with a git push origin +master:master
, the +
sign forcing the push to occur, even if it doesn't result in a "fast-forward" commit)... you might get into some trouble.
Extract from this other SO question:
I actually once pushed with --force to git.git repository and got scolded by Linus BIG TIME. It will create a lot of problems for other people. A simple answer is "don't do it".
Some operations are quicker than java heap space manager. Delaying operations for some time can free memory space. You can use this method to escape heap size error:
waitForGarbageCollector(new Runnable() {
@Override
public void run() {
// Your operations.
}
});
/**
* Measure used memory and give garbage collector time to free up some
* of the space.
*
* @param callback Callback operations to be done when memory is free.
*/
public static void waitForGarbageCollector(final Runnable callback) {
Runtime runtime;
long maxMemory;
long usedMemory;
double availableMemoryPercentage = 1.0;
final double MIN_AVAILABLE_MEMORY_PERCENTAGE = 0.1;
final int DELAY_TIME = 5 * 1000;
runtime =
Runtime.getRuntime();
maxMemory =
runtime.maxMemory();
usedMemory =
runtime.totalMemory() -
runtime.freeMemory();
availableMemoryPercentage =
1 -
(double) usedMemory /
maxMemory;
if (availableMemoryPercentage < MIN_AVAILABLE_MEMORY_PERCENTAGE) {
try {
Thread.sleep(DELAY_TIME);
} catch (InterruptedException e) {
e.printStackTrace();
}
waitForGarbageCollector(
callback);
} else {
// Memory resources are available, go to next operation:
callback.run();
}
}
Had the same problem, but solved it in a different way. It might not be the best solution, but its a solution.
in app.config:
<add key="errorMailFirst" value="[email protected]"/>
<add key="errorMailSeond" value="[email protected]"/>
Then in my configuration wrapper class, I add a method to search keys.
public List<string> SearchKeys(string searchTerm)
{
var keys = ConfigurationManager.AppSettings.Keys;
return keys.Cast<object>()
.Where(key => key.ToString().ToLower()
.Contains(searchTerm.ToLower()))
.Select(key => ConfigurationManager.AppSettings.Get(key.ToString())).ToList();
}
For anyone reading this, i agree that creating your own custom configuration section is cleaner, and more secure, but for small projects, where you need something quick, this might solve it.
Works with modification
You need to set the text view size like this because otherwise setTextSize assumes the value is in SP units:
setTextSize(TypedValue.COMPLEX_UNIT_PX, trySize);
And you needed to explicitly add this code.
@Override
protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec)
{
super.onMeasure(widthMeasureSpec, heightMeasureSpec);
int parentWidth = MeasureSpec.getSize(widthMeasureSpec);
int parentHeight = MeasureSpec.getSize(heightMeasureSpec);
refitText(this.getText().toString(), parentWidth);
}
DateTime _expiryDate = DateTime.Now + TimeSpan.FromDays(30);
In the nav go View => Layout => Columns:2
(alt+shift+2
) and open your file again in the other pane (i.e. click the other pane and use ctrl+p filename.py
)
It appears you can also reopen the file using the command File -> New View into File
which will open the current file in a new tab
Same question as @Dan - why not StringReader ?
If it has to be InputStreamReader, then:
String charset = ...; // your charset
byte[] bytes = string.getBytes(charset);
ByteArrayInputStream bais = new ByteArrayInputStream(bytes);
InputStreamReader isr = new InputStreamReader(bais);
There is a commercial tool FlexTracer which can be used to trace Oracle SQL queries
If you are embracing the type hints in Python 3.6, you can do it like this:
def from_json(data, cls):
annotations: dict = cls.__annotations__ if hasattr(cls, '__annotations__') else None
if issubclass(cls, List):
list_type = cls.__args__[0]
instance: list = list()
for value in data:
instance.append(from_json(value, list_type))
return instance
elif issubclass(cls, Dict):
key_type = cls.__args__[0]
val_type = cls.__args__[1]
instance: dict = dict()
for key, value in data.items():
instance.update(from_json(key, key_type), from_json(value, val_type))
return instance
else:
instance : cls = cls()
for name, value in data.items():
field_type = annotations.get(name)
if inspect.isclass(field_type) and isinstance(value, (dict, tuple, list, set, frozenset)):
setattr(instance, name, from_json(value, field_type))
else:
setattr(instance, name, value)
return instance
Which then allows you do instantiate typed objects like this:
class Bar:
value : int
class Foo:
x : int
bar : List[Bar]
obj : Foo = from_json(json.loads('{"x": 123, "bar":[{"value": 3}, {"value": 2}, {"value": 1}]}'), Foo)
print(obj.x)
print(obj.bar[2].value)
This syntax requires Python 3.6 though and does not cover all cases - for example, support for typing.Any... But at least it does not pollute the classes that need to be deserialized with extra init/tojson methods.
OCR which stands for Optical Character Recognition is a computer vision technique used to identify the different types of handwritten digits that are used in common mathematics. To perform OCR in OpenCV we will use the KNN algorithm which detects the nearest k neighbors of a particular data point and then classifies that data point based on the class type detected for n neighbors.
Data Used
This data contains 5000 handwritten digits where there are 500 digits for every type of digit. Each digit is of 20×20 pixel dimensions. We will split the data such that 250 digits are for training and 250 digits are for testing for every class.
Below is the implementation.
import numpy as np import cv2 # Read the image image = cv2.imread( 'digits.png' ) # gray scale conversion gray_img = cv2.cvtColor(image, cv2.COLOR_BGR2GRAY) # We will divide the image # into 5000 small dimensions # of size 20x20 divisions = list (np.hsplit(i, 100 ) for i in np.vsplit(gray_img, 50 )) # Convert into Numpy array # of size (50,100,20,20) NP_array = np.array(divisions) # Preparing train_data # and test_data. # Size will be (2500,20x20) train_data = NP_array[:,: 50 ].reshape( - 1 , 400 ).astype(np.float32) # Size will be (2500,20x20) test_data = NP_array[:, 50 : 100 ].reshape( - 1 , 400 ).astype(np.float32) # Create 10 different labels # for each type of digit k = np.arange( 10 ) train_labels = np.repeat(k, 250 )[:,np.newaxis] test_labels = np.repeat(k, 250 )[:,np.newaxis] # Initiate kNN classifier knn = cv2.ml.KNearest_create() # perform training of data knn.train(train_data, cv2.ml.ROW_SAMPLE, train_labels) # obtain the output from the # classifier by specifying the # number of neighbors. ret, output ,neighbours, distance = knn.findNearest(test_data, k = 3 ) # Check the performance and # accuracy of the classifier. # Compare the output with test_labels # to find out how many are wrong. matched = output = = test_labels correct_OP = np.count_nonzero(matched) #Calculate the accuracy. accuracy = (correct_OP * 100.0 ) / (output.size) # Display accuracy. print (accuracy) |

Well, I decided to workout myself on my question to solve the above problem. What I wanted is to implement a simple OCR using KNearest or SVM features in OpenCV. And below is what I did and how. (it is just for learning how to use KNearest for simple OCR purposes).
1) My first question was about letter_recognition.data
file that comes with OpenCV samples. I wanted to know what is inside that file.
It contains a letter, along with 16 features of that letter.
And this SOF
helped me to find it. These 16 features are explained in the paper Letter Recognition Using Holland-Style Adaptive Classifiers
.
(Although I didn't understand some of the features at the end)
2) Since I knew, without understanding all those features, it is difficult to do that method. I tried some other papers, but all were a little difficult for a beginner.
So I just decided to take all the pixel values as my features. (I was not worried about accuracy or performance, I just wanted it to work, at least with the least accuracy)
I took the below image for my training data:
(I know the amount of training data is less. But, since all letters are of the same font and size, I decided to try on this).
To prepare the data for training, I made a small code in OpenCV. It does the following things:
key press manually
. This time we press the digit key ourselves corresponding to the letter in the box..txt
files.At the end of the manual classification of digits, all the digits in the training data (train.png
) are labeled manually by ourselves, image will look like below:
Below is the code I used for the above purpose (of course, not so clean):
import sys
import numpy as np
import cv2
im = cv2.imread('pitrain.png')
im3 = im.copy()
gray = cv2.cvtColor(im,cv2.COLOR_BGR2GRAY)
blur = cv2.GaussianBlur(gray,(5,5),0)
thresh = cv2.adaptiveThreshold(blur,255,1,1,11,2)
################# Now finding Contours ###################
contours,hierarchy = cv2.findContours(thresh,cv2.RETR_LIST,cv2.CHAIN_APPROX_SIMPLE)
samples = np.empty((0,100))
responses = []
keys = [i for i in range(48,58)]
for cnt in contours:
if cv2.contourArea(cnt)>50:
[x,y,w,h] = cv2.boundingRect(cnt)
if h>28:
cv2.rectangle(im,(x,y),(x+w,y+h),(0,0,255),2)
roi = thresh[y:y+h,x:x+w]
roismall = cv2.resize(roi,(10,10))
cv2.imshow('norm',im)
key = cv2.waitKey(0)
if key == 27: # (escape to quit)
sys.exit()
elif key in keys:
responses.append(int(chr(key)))
sample = roismall.reshape((1,100))
samples = np.append(samples,sample,0)
responses = np.array(responses,np.float32)
responses = responses.reshape((responses.size,1))
print "training complete"
np.savetxt('generalsamples.data',samples)
np.savetxt('generalresponses.data',responses)
Now we enter in to training and testing part.
For the testing part, I used the below image, which has the same type of letters I used for the training phase.
For training we do as follows:
.txt
files we already saved earlierFor testing purposes, we do as follows:
I included last two steps (training and testing) in single code below:
import cv2
import numpy as np
####### training part ###############
samples = np.loadtxt('generalsamples.data',np.float32)
responses = np.loadtxt('generalresponses.data',np.float32)
responses = responses.reshape((responses.size,1))
model = cv2.KNearest()
model.train(samples,responses)
############################# testing part #########################
im = cv2.imread('pi.png')
out = np.zeros(im.shape,np.uint8)
gray = cv2.cvtColor(im,cv2.COLOR_BGR2GRAY)
thresh = cv2.adaptiveThreshold(gray,255,1,1,11,2)
contours,hierarchy = cv2.findContours(thresh,cv2.RETR_LIST,cv2.CHAIN_APPROX_SIMPLE)
for cnt in contours:
if cv2.contourArea(cnt)>50:
[x,y,w,h] = cv2.boundingRect(cnt)
if h>28:
cv2.rectangle(im,(x,y),(x+w,y+h),(0,255,0),2)
roi = thresh[y:y+h,x:x+w]
roismall = cv2.resize(roi,(10,10))
roismall = roismall.reshape((1,100))
roismall = np.float32(roismall)
retval, results, neigh_resp, dists = model.find_nearest(roismall, k = 1)
string = str(int((results[0][0])))
cv2.putText(out,string,(x,y+h),0,1,(0,255,0))
cv2.imshow('im',im)
cv2.imshow('out',out)
cv2.waitKey(0)
And it worked, below is the result I got:
Here it worked with 100% accuracy. I assume this is because all the digits are of the same kind and the same size.
But anyway, this is a good start to go for beginners (I hope so).
JavaScript only has a Number type that stores floating point values.
There is no int.
Edit:
If you want to format the number as a string with two digits after the decimal point use:
(4).toFixed(2)
Simplest way is to Check the Output - Build tab: It would display the location of war file.
It will have something like:
Installing D:\Project\target\Tool.war to C:\Users\myname.m2\repository\com\tool\1.0\Tool-1.0.war
A lot of problems can be avoided by only creating a branch
to work on & not working on master
:
git checkout -b mybranch
The following works for remote
commits already pushed & a mixture of remote
pushed commits / local
only commits:
# example merging 4 commits
git checkout mybranch
git rebase -i mybranch~4 mybranch
# at the interactive screen
# choose fixup for commit: 2 / 3 / 4
git push -u origin +mybranch
I also have some pull request notes which may be helpful.
I believe that, if you need to use the %20
variant, you could perhaps use rawurlencode()
.
You could use KBKeyboardObserver library. It contains some examples and provides simple interface.
You have to make the UL
inside the div
behave like a block. Try adding
.navigation ul {
display: inline-block;
}
If you have named datasets in the hdf file then you can use the following code to read and convert these datasets in numpy arrays:
import h5py
file = h5py.File('filename.h5', 'r')
xdata = file.get('xdata')
xdata= np.array(xdata)
If your file is in a different directory you can add the path in front of'filename.h5'
.
It turns out that OpenSSL is compiled and enabled in php 5.3 of XAMPP 1.7.2 and so no longer requires a separate extension dll.
However, you STILL need to enable it in your PHP.ini file the line extension=php_openssl.dll
Instead of using Html.ActionLink you can render a url via Url.Action
<a href="<%= Url.Action("Index", "Home") %>"><span>Text</span></a>
<a href="@Url.Action("Index", "Home")"><span>Text</span></a>
And to do a blank url you could have
<a href="<%= Url.Action("Index", "Home") %>"></a>
<a href="@Url.Action("Index", "Home")"></a>
It is most likely that you got your repo's SSH URL wrong.
To confirm, go to your repository on Github and click the clone or download button
. Then click the use SSH
link.
Now copy your official repo's SSH link. Mine looked like this - [email protected]:borenho/que-ay.git
You can now do git remote add origin [email protected]:borenho/que-ay.git
if you didn't have origin
yet.
If you had set origin
before, change it by using git remote set-url origin [email protected]:borenho/que-ay.git
Now push with git push -u origin master
Just assuming this is for a regular expression, use re.escape
.
You can create helper generic, static method to create list:
internal static class List
{
public static List<T> Of<T>(params T[] args)
{
return new List<T>(args);
}
}
And then usage is very compact:
List.Of("test1", "test2", "test3")
Update 2021, Bootstrap 5
In bootstrap 5 these classes have been renamed to .float-end
and .float-start
.
Docs: https://getbootstrap.com/docs/5.0/utilities/float/
Example:
<div class="row">
<div class="col-12">
<button class="btn btn-primary float-end">Login</div>
</div>
</div>
The Taylor series is one way to approximate pi. As noted it converges slowly.
The partial sums of the Taylor series can be shown to be within some multiplier of the next term away from the true value of pi.
Other means of approximating pi have similar ways to calculate the max error.
We know this because we can prove it mathematically.
You could add a method to String to make it more semantic:
String.metaClass.getNotBlank = { !delegate.allWhitespace }
which let's you do:
groovy:000> foo = ''
===>
groovy:000> foo.notBlank
===> false
groovy:000> foo = 'foo'
===> foo
groovy:000> foo.notBlank
===> true
I feel like this is the simplest way. (Feel free to change the width and height values).
<a href="http://www.google.com"
target="popup"
onclick="window.open('http://www.google.com','popup','width=600,height=600'); return false;">

I found a solution: use :hover
with cursor: pointer
if nothing else helps.
Yes, basically what you done is right, except you forget that JavaScript is sync in many cases, so you running the code before your DOM gets loaded, there are few ways to solve this:
1) Check to see if DOM fully loaded, then do whatever you want, you can listen to DOMContentLoaded for example:
<script>
document.addEventListener("DOMContentLoaded", function(event) {
console.log("DOM fully loaded and parsed");
});
</script>
2) Very common way is adding the script tag to the bottom of your document
(after body tag):
<html>
<head>
</head>
<body>
</body>
<script src="/bundle.js"></script>
</html>
3) Using window.onload
, which gets fired when the entire page loaded(img, etc)
window.addEventListener("load", function() {
console.log("Everything is loaded");
});
4) Using document.onload
, which gets fired when the DOM is ready:
document.addEventListener("load", function() {
console.log("DOM is ready");
});
There are even more options to check if DOM is ready, but the short answer is DO NOT run any script before you make sure your DOM is ready in every cases...
JavaScript is working along with DOM elements and if they are not available, will return null, could break the whole application... so always make sure you are fully ready to run your JavaScript before you do...
When you create an App, a file called styles.xml will be created in your res/values folder. If you change the styles, you can change the background, text color, etc for all your layouts. That way you don’t have to go into each individual layout and change the it manually.
styles.xml:
<resources xmlns:android="http://schemas.android.com/apk/res/android">
<style name="Theme.AppBaseTheme" parent="@android:style/Theme.Light">
<item name="android:editTextColor">#295055</item>
<item name="android:textColorPrimary">#295055</item>
<item name="android:textColorSecondary">#295055</item>
<item name="android:textColorTertiary">#295055</item>
<item name="android:textColorPrimaryInverse">#295055</item>
<item name="android:textColorSecondaryInverse">#295055</item>
<item name="android:textColorTertiaryInverse">#295055</item>
<item name="android:windowBackground">@drawable/custom_background</item>
</style>
<!-- Application theme. -->
<style name="AppTheme" parent="AppBaseTheme">
<!-- All customizations that are NOT specific to a particular API-level can go here. -->
</style>
parent="@android:style/Theme.Light"
is Google’s native colors. Here is a reference of what the native styles are:
https://android.googlesource.com/platform/frameworks/base/+/refs/heads/master/core/res/res/values/themes.xml
The default Android style is also called “Theme”. So you calling it Theme probably confused the program.
name="Theme.AppBaseTheme"
means that you are creating a style that inherits all the styles from parent="@android:style/Theme.Light"
.
This part you can ignore unless you want to inherit from AppBaseTheme again. = <style name="AppTheme" parent="AppBaseTheme">
@drawable/custom_background is a custom image I put in the drawable’s folder. It is a 300x300 png image.
#295055 is a dark blue color.
My code changes the background and text color. For Button text, please look through Google’s native stlyes (the link I gave u above).
Then in Android Manifest, remember to include the code:
<application
android:theme="@style/Theme.AppBaseTheme">
You could use a temporary swap variable or XOR.
a = a ^ b
b = a ^ b
a = a ^ b
This is just a basic logical concept and works in every language that supports XOR operation.
edit: see the Comments. Forgot to tell that this works for sure only with integer. Assumed the integer variables from question's thread
You want the (standard) POSIXt
type from base R that can be had in 'compact form' as a POSIXct
(which is essentially a double representing fractional seconds since the epoch) or as long form in POSIXlt
(which contains sub-elements). The cool thing is that arithmetic etc are defined on this -- see help(DateTimeClasses)
Quick example:
R> now <- Sys.time()
R> now
[1] "2009-12-25 18:39:11 CST"
R> as.numeric(now)
[1] 1.262e+09
R> now + 10 # adds 10 seconds
[1] "2009-12-25 18:39:21 CST"
R> as.POSIXlt(now)
[1] "2009-12-25 18:39:11 CST"
R> str(as.POSIXlt(now))
POSIXlt[1:9], format: "2009-12-25 18:39:11"
R> unclass(as.POSIXlt(now))

As for reading them in, see help(strptime)
As for difference, easy too:
R> Jan1 <- strptime("2009-01-01 00:00:00", "%Y-%m-%d %H:%M:%S")
R> difftime(now, Jan1, unit="week")

Lastly, the zoo package is an extremely versatile and well-documented container for matrix with associated date/time indices.
The alternative for explode in php is split.
The first parameter is the delimiter, the second parameter the maximum number splits. The parts are returned without the delimiter present (except possibly the last part). When the delimiter is None, all whitespace is matched. This is the default.
>>> "Rajasekar SP".split()
['Rajasekar', 'SP']
>>> "Rajasekar SP".split('a',2)
['R','j','sekar SP']
@Morwenn is right.
You need to config the openssl DIR.
Before that you may need to make sure you have it.
you should check whether you have it.
first run openssl version
,then if you have it you can win + r
run openssl
and you win find the core dir since it may not name as openssl in your system.
If you are trying to install it in an Emulator but have another phone connected to the computer via USB, detach the USB cable or disable USB debugging in the physical device. (Wasted 30min on it myself.)
I needed a more flexible solution for working on multiple git repositories so I wrote the following sh code based on 1 and 2. You can use your server address instead of gitlab.com and your port in replace of 22.
SERVER=gitlab.com
PORT=22
nc -z -v -w5 $SERVER $PORT
result1=$?
#Do whatever you want
if [ "$result1" != 0 ]; then
echo 'port 22 is closed'
else
echo 'port 22 is open'

Get rid from your <Button>
wrap div using display:block
and float:left
in both <Button>
and <h1>
and specifying their width
with a position:relative
to your Section
. This approach has the advantage of not needing another div
only to position your <Button>
html
<section>
<h1>some long long long long header, a whole line, 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6</h1>
<button>button</button>
</section>

section {
position: relative;
width: 50%;

From the perspective of managing complexity, a primary software engineering objective, we want to avoid propagating unnecessary cyclomatic complexity to the clients of an API. Returning a null to the client is like returning them the cyclomatic complexity cost of another code branch.
(This corresponds to a unit testing burden. You would need to write a test for the null return case, in addition to the empty collection return case.)
If your column is of type DATE (as you say), then you don't need to convert it into a string first (in fact you would convert it implicitly to a string first, then explicitly to a date and again explicitly to a string):
SELECT TO_CHAR(COL1, 'mm/dd/yyyy') FROM TABLE1
The date format your seeing for your column is an artifact of the tool your using (TOAD, SQL Developer etc.) and it's language settings.
Due to the mixed comments about BuildConfig.DEBUG
, I used the following to disable crashlytics (and analytics) in debug mode :
update /app/build.gradle
android {
compileSdkVersion 25
buildToolsVersion "25.0.1"
defaultConfig {
applicationId "your.awesome.app"
minSdkVersion 16
targetSdkVersion 25
versionCode 100
versionName "1.0.0"
buildConfigField 'boolean', 'ENABLE_CRASHLYTICS', 'true'
}
buildTypes {
debug {
debuggable true
minifyEnabled false
buildConfigField 'boolean', 'ENABLE_CRASHLYTICS', 'false'
}
release {
debuggable false
minifyEnabled true
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
}
}
}
then, in your code you detect the ENABLE_CRASHLYTICS
flag as follows:
if (BuildConfig.ENABLE_CRASHLYTICS)
{
// enable crashlytics and answers (Crashlytics by default includes Answers)
Fabric.with(this, new Crashlytics());
}
use the same concept in your app and rename ENABLE_CRASHLYTICS
to anything you want. I like this approach because I can see the flag in the configuration and I can control the flag.
i had the same problem and i found that Microsoft has a systable that shows dependencies.
SELECT
referenced_id
, referenced_entity_name AS table_name
, referenced_minor_name as column_name
, is_all_columns_found
FROM sys.dm_sql_referenced_entities ('dbo.Proc1', 'OBJECT');
And this works with both Views
and Triggers
.
I have 2 servers setup on docker, reverse proxy & web server. This error started happening for all my websites all of a sudden after 1 year. When setting up earlier, I generated a self signed certificate on the web server.
So, I had to generate the SSL certificate again and it started working...

It is txtName.BackColor = System.Drawing.Color.Red;
one can also use txtName.BackColor = Color.Aqua;
which is the same as txtName.BackColor = System.Color.Aqua;
Only Problem with System.color is that it does not contain a definition for some basic colors especially white, which is important cause usually textboxes are white;
Go to http://nodejs.org and download and run the installer. It works now - for me at least.
Chr(10)
is the Line Feed character and Chr(13)
is the Carriage Return character.
You probably won't notice a difference if you use only one or the other, but you might find yourself in a situation where the output doesn't show properly with only one or the other. So it's safer to include both.
Historically, Line Feed would move down a line but not return to column 1:
This
is
a
test.
Similarly Carriage Return would return to column 1 but not move down a line:
This
is
a
test.
Paste this into a text editor and then choose to "show all characters", and you'll see both characters present at the end of each line. Better safe than sorry.
simply in your css use '.ui-datepicker{ z-index: 9999 !important;}
' Here 9999 can be replaced to whatever layer value you want your datepicker available. Neither any code is to be commented nor adding 'position:relative;
' css on input elements. Because increasing the z-index of input elements will have effect on all input type buttons, which may not be needed for some cases.

I resolved this problem by navigating to C:\Python27\Scripts folder and then run file.py file instead of C:\Python27 folder
I had a similar problem running SciPy on my computer. There are two ways to fix this problem: 1. Yes you do need to cd into your python directory. 2. Sometimes you have to tell the computer explicitly what path to go through, you have to find the program you're using, open up the properties, and reroute the path it takes to run. 3. consult the manual: http://matplotlib.org/users/installing.html or http://www.scipy.org/install.html
the Scipy package is very finicky, and needs things spelled out in obnoxious detail.
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!
I needed something similar, the ability to click on a set of icons to indicate a choice, or a text-based choice and have that update the model (2-way-binding) with the represented value and to also a way to indicate which was selected visually. I created an AngularJS directive for it, since it needed to be flexible enough to handle any HTML element being clicked on to indicate a choice.
<ul ng-repeat="vote in votes" ...>
<li data-choice="selected" data-value="vote.id">...</li>
</ul>
NPM is a package manager, you can install node.js packages using NPM
NPX is a tool to execute node.js packages.
It doesn't matter whether you installed that package globally or locally. NPX will temporarily install it and run it. NPM also can run packages if you configure a package.json file and include it in the script section.
So remember this, if you want to check/run a node package quickly without installing locally or globally use NPX.
npM - Manager
npX - Execute - easy to remember
You need to use ECHO
. Also, put the quotes around the entire file path if it contains spaces.
One other note, use >
to overwrite a file if it exists or create if it does not exist. Use >>
to append to an existing file or create if it does not exist.
Overwrite the file with a blank line:
ECHO.>"C:\My folder\Myfile.log"
Append a blank line to a file:
ECHO.>>"C:\My folder\Myfile.log"
Append text to a file:
ECHO Some text>>"C:\My folder\Myfile.log"
Append a variable to a file:
ECHO %MY_VARIABLE%>>"C:\My folder\Myfile.log"
Can also be done like this:
var textContents = $(document.getElementById("ElementId").childNodes).filter(function(){
return this.nodeType == 3;
});
The above code filters the textNodes from direct children child nodes of a given element.
Here is my take:
cmake_minimum_required(VERSION 3.15)
project(TryOuts LANGUAGES CXX)
find_package(Boost QUIET REQUIRED COMPONENTS program_options)
if(NOT Boost_FOUND)
message(FATAL_ERROR "Boost Not found")
endif()
add_executable(helloworld main.cpp)
target_link_libraries(helloworld PUBLIC Boost::program_options)
min(df['some_property'])
max(df['some_property'])
The built-in functions work well with Pandas Dataframes.
You could set the corresponding value in the ViewData/ViewBag
:
ViewData["hdnFlag"] = "some value";
But a much better approach is to of course use a view model:
model.hdnFlag = "some value";
return View(model);
and use a strongly typed helper in your view:
@Html.HiddenFor(x => x.hdnFlag, new { id = "hdnFlag" })
